DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] Before the present features and working principle of a power management system for a battery-operated vehicle is described, it is to be understood that this subject matter is not limited to the particular system as described, since it may vary within the specification indicated. Various features of a power management system for a battery-operated vehicle might be provided by introducing variations within the components/subcomponents disclosed herein. It is also to be understood that the terminology used in the description is for the purpose of describing the particular versions or embodiments only, and is not intended to limit the scope of the present subject matter, which will be limited only by the appended claims.

[0033] It should be understood that the present subject matter describes a power management system for battery-operated vehicle. The power management system includes an electric motor. The electric motor connects to a drive shaft of the vehicle. The vehicle moves resulting in movement of moving parts in the vehicle. The power management system includes kinetic energy devices for capturing kinetic friction energy produced by the moving parts. A central direct current (DC) supercharge component (CDCSC) converts the kinetic friction energy into an electric current. The CDCSC connects to a current toggle that directs the electric current to battery packs i.e., a first battery pack and a second battery pack for powering the electric motor. The current toggle directs the electric current to the battery packs to recharge or store power. The power management system governs power output from the battery packs, manages depletion and efficiency of the battery packs. The power management system includes a parallel port that directs outgoing power feeds from the battery packs to the electric motor. The electric motor connects to a drive shaft of the vehicle. The power management system includes an additional battery pack that stores excess kinetic friction energy captured for external transfer.

[0034] Various features and embodiments of the power management system for a battery-operated vehicle are explained in conjunction with the description of FIGS. 1-8.

[0035] The present subject matter discloses a power management system for a battery-operated vehicle. FIG. 1 shows environment 10 in which power management system 12 implements in vehicle 14, in accordance with one embodiment of the present subject matter. The term “vehicle” as used herein refers to either an all-electric vehicle, also referred to as an EV, or a battery-operated vehicle, plug-in hybrid vehicles, also referred to as a PHEV, or a hybrid vehicle (HEV), a hybrid vehicle utilizing multiple propulsion sources one of which is an electric drive system. Here, vehicle 14 includes a motor cycle, car, truck, boat, train or any other vehicle that operates on energy stored in a battery.

[0036] The present description is explained considering that vehicle 14 is a car. However, a person skilled in the art understands other vehicles 12 as presented above may also implement the presently disclosed power management system 12 for operating vehicle 14. Vehicle 14 encompasses axle 16 connecting wheels 18, say at the front and rear of vehicle 14. Axle 16 connects to drive shaft or power train 20 that controls movement of vehicle 14. In accordance with one embodiment of the present subject matter, power management system 12 includes one or more kinetic capture devices such as first kinetic capture device 22a, second kinetic capture device 22b and third kinetic capture device 22c, collectively referred as kinetic capture devices 22. FIG. 1 shows first kinetic capture device 22a and second kinetic capture device 22b connecting to axle 16, and third kinetic capture device 22c to drive shaft 20. However, a person skilled in the art understands kinetic capture devices 22 connect in any number depending on the moving parts present in vehicle 14. A person skilled in the art understands FIG. 2 illustrates axle 16 containing multiple smaller kinetic capture devices 22 of smaller configuration. Further, FIGS. 3 and 4 illustrate a single elongated kinetic capture device 22 that extends substantial or entire length of axle 16. FIGS. 2, 3 and 4 show one or more kinetic capture devices 22 connect over the length of axle 16. A person skilled in the art understands that one or more kinetic capture devices 22 connect over the length of drive shaft 20 without departing from the scope of the present subject matter.

[0037] Now referring to FIGS. 1 and 5, working of power management system 12 in vehicle 14 is explained. As specified above, FIG. 1 shows environment 10 in which power management system 12 implements in vehicle 14. FIG. 5 shows a block diagram of power management system 12, in accordance with one embodiment of the present subject matter. As specified above, power management system 12 includes kinetic capture devices 22. Kinetic capture devices 22 connect to axle 16 and/or drive shaft 20. Kinetic capture devices 22 connect on, near, and/or around axle 16 and/or drive shaft 20 in a variety of patterns. Each of kinetic capture devices 22 captures kinetic friction energy from movement of moving parts in vehicle 14. In one example, kinetic capture devices 22 captures kinetic friction energy from axle 16, drive shaft 20, braking, sensors, axle friction recharge, wheel rotation friction recharge, brake pad friction, exterior vehicle/mechanism friction capture, wind/water (hull friction, wake, etc.), solar surface on vehicle 14, etc. Each of kinetic capture devices 22 captures the kinetic friction energy produced by movement of moving parts in vehicle 14, and transfers the kinetic friction energy via flow transfer cable(s) 23 to central direct current (DC) supercharge component 24, hereinafter referred as CDCSC 24. In one implementation, one or more kinetic capture devices 22 attach to axle 16 and/or drive shaft 20, each kinetic capture device 22 delivering a single or multiple distinct electric charge(s) to CDCSC 24 via flow transfer cable 23, as shown in FIG. 2, for example. FIG. 2 shows an exemplary embodiment in which axle 16 including seven kinetic capture devices 22 i.e., first kinetic capture device 22a, second kinetic capture device 22b, third kinetic capture device 22c, fourth kinetic capture device 22d, fifth kinetic capture device 22e, sixth kinetic capture device 22f and seventh kinetic capture device 22g. A person skilled in the art understands that the number of flow transfer cables 23 used for transferring the kinetic friction energy produced by kinetic capture devices 22 to CDCSC 24 changes depending on the need and/or pattern of kinetic capture devices 22 placed over axle 16 and/or drive shaft 20.

[0038] In another implementation, axle 16 and/or drive shaft 20 surrounds or contains entirely or substantially by a single kinetic capture device 22a. FIG. 3 shows an exemplary embodiment in which a single kinetic capture device 22 connecting along the substantial length of axle 16. Additionally, kinetic capture device 22 connect along the substantial length of drive shaft 20. Here, kinetic capture device 22a engages axle 16 and/or drive shaft 20 directly or fully. Kinetic capture device 22a employs a single or multiple distinct reporting and delivering electric charge(s) to CDCSC 24 via flow transfer cable 23, as shown in FIG. 3, for example.

[0039] In another implementation, axle 16 and/or drive shaft 20 come precast (manufactured together with or fully integrated) with kinetic capture device 22a. FIG. 4 shows an exemplary embodiment in which a single kinetic capture devices 22 extends over the entire length of axle 16. Optionally, kinetic capture device 22 extend over the entire length of drive shaft 20. Here, kinetic capture device 22a engages axle 16 and/or drive shaft 20 directly and/or fully. Kinetic capture device 22a employs a single or multiple distinct reporting and delivering electric charge(s) to CDCSC 24 via flow transfer cable 23, as shown in FIG. 4, for example.

[0040] Upon receiving the kinetic friction energy captured by kinetic capture devices 22, CDCSC 24 converts the kinetic friction energy captured to a DC electric current. Subsequently, CDCSC 24 directs the DC electric current to battery packs i.e., first battery pack 32 and second battery pack 36 via current toggle 28. The DC electric current is used for charging or recharging first battery pack 32 and second battery pack 36. Current toggle 28 directs the DC electric current to traffick and provide constant recharging one of first battery pack 32 and second battery pack 36. In one example, current toggle 28 includes controller 30. Controller 30 simultaneously switches the flow of incoming DC current to one of first battery pack 32 and second battery pack 36, as it immediately begins recharging for later toggle back. Controller 30 includes a software/hardware module that stores charge levels of first battery pack 32 and second battery pack 36. Further, controller 30 maintains and records the depletion point or predefined threshold levels of charge to switch charging of first battery pack 32 and second battery pack 36 by current toggle 28. In addition, current toggle 28 directs the incoming DC electric charge to third battery back 44 when first battery pack 32 and second battery pack 36 are fully charged or when a rollover option is engaged. The rollover charge indicates a charge that is not immediately needed for recharge of the secondary battery source. In other words, when the secondary battery source (in charging position) attains full charge from the kinetic charge devices feed while the primary battery source is still operational and not depleted, then the residual electric charge generated from the kinetic charge devices is referred as overflow charge” or “rollover charge”. In one implementation, current toggle 28 monitors charge, output levels, switchover needs of first battery pack 32 and second battery pack 36 and functional reports of axle 16 and drive shaft 20.

[0041] In one implementation, CDCSC 24 connects to Thermophotovoltaics (TPV) heat sensors 26. TPV heat sensors 26 includes one or more heat management and transference sensors that surround battery packs i.e., first battery pack 32 and second battery pack 36. TPV heat sensors 26 act as heat contact sensors. TPV heat sensors 26 capture the heat produced from first battery pack 32 and second battery pack 36 and create a distinct DC electric current (current charge). The distinct DC electric current is then directed to and fed into CDCSC 24 (FIG. 5). In accordance with one embodiment of the present subject matter, TPV heat sensors 26 provide additional sourcing of electric current generated (in addition to kinetic friction energy created by kinetic capture devices 22) in power management system 12. As such, TPV heat sensors 26 serve as an additional recharge power and heat management system for battery packs i.e., first battery pack 32 and second battery pack 36.

[0042] In another implementation, CDCSC 24 connects to additional sensors. Additional sensors, include, but not limited to, including solar, wind flow drag over vehicle surfaces, water flow (hydro drag) over hull, compression, additional friction, etc.

[0043] As can be seen from FIGS. 1 and 5, current toggle 28 connects to battery packs i.e., first battery pack 32 and second battery pack 36 to direct and control the flow of DC electric current for charging them. First battery pack 32 and second battery pack 36 are identical but distinct battery packs. The term “battery pack” as used herein refers to multiple individual batteries contained within a single piece or multi-piece housing, the individual batteries electrically interconnected to achieve the desired voltage and capacity for a particular application. The terms, “battery”, “cell”, and “battery cell” may be used interchangeably and may refer to any of a variety of different cell types, chemistries and configurations including, but not limited to, lithium ion (e.g., lithium iron phosphate, lithium cobalt oxide, other lithium metal oxides, etc.), lithium ion polymer, nickel metal hydride, nickel cadmium, nickel hydrogen, lithium-nickel-cobalt-aluminium, lithium-nickel-manganese-cobalt, nickel zinc, silver zinc, or other battery type/configuration.

[0044] Here, each of first battery pack 32 and second battery pack 36 includes a non-metal-air battery pack or metal-air battery pack, depending on the need. Given the high energy density and the large capacity-to-weight ratio offered by metal-air cells, they are well suited for use in vehicle 14. Due to their limited power density, however, their use is most appropriate when combined with a more conventional power source, such as a lithium ion battery pack. As used herein, metal-air batteries refer to any cell that utilizes oxygen as one of the electrodes and metal (e.g., zinc, aluminium, magnesium, iron, lithium, vanadium, etc.) in the construction of the other electrode. Battery pack that utilizes non-metal-air cells provide high power density, thus providing a combined power source that achieves an optimal combination of energy and power. Exemplary batteries that use non-metal-air cells include, but are not limited to, lithium ion (e.g., lithium iron phosphate, lithium cobalt oxide, other lithium metal oxides, etc.), lithium ion polymer, nickel metal hydride, nickel cadmium, nickel hydrogen, nickel zinc, silver zinc, etc.

[0045] First battery pack 32 includes first power output flow governor 34. First power output flow governor 34 indicates a software and/or hardware module that installs on the output flow of first battery pack 32 and communicatively connects to current toggle 28. First power output flow governor 34 maintains a power output ceiling for first power output flow governor 34 when one of first battery pack 32 and second battery pack 36 acts as a primary battery source for providing operating power to electric motor 42. First power output flow governor 34 manages battery power to effectively reach maximum, nearly unlimited EV range and uninterrupted operational time which is critical to maximizing operational performance of power management system 12 and/or vehicle 14. First power output flow governor 34 ensures the battery power usage is sufficient to deliver the maximum power to electric motor 42 for the longest timeframe, thus enabling charging of second battery pack 36 to gain full recharge time. First power output flow governor 34 operates to ensure vehicle 14 still maintains plenty of acceleration capacity and torque to achieve normal speed and operational needs for the user of vehicle 14. In addition, first power output flow governor 34 maintains efficient power flow so as not to drain the battery power supply.

[0046] Similarly, second battery pack 36 includes second power output flow governor 38. Second power output flow governor 38 indicates a software and/or hardware module that installs on the output flow of second battery pack 36 and communicatively connects to current toggle 28. Second power output flow governor 38 maintains a power output ceiling for second power output flow governor 38 when one of first battery pack 32 and second battery pack 36 acts as a primary battery source for providing operating power to electric motor 42. Second power output flow governor 38 manages battery power to effectively reach maximum, nearly unlimited EV range and uninterrupted operational time which is critical to maximizing operational performance of power management system 12 and/or vehicle 14. Second power output flow governor 38 ensures the battery power usage is sufficient to deliver the maximum power to electric motor 42 for the longest timeframe, thus enabling charging of first battery pack 32 to gain full recharge time. Second power output flow governor 38 operates to ensure vehicle 14 still maintains plenty of acceleration capacity and torque to achieve normal speed and operational needs for the user of vehicle 14. In addition, second power output flow governor 38 maintains efficient power flow so as not to drain the battery power supply.

[0047] Each of first battery pack 32 and second battery pack 36 connects to parallel port 40 that directs/delivers the power output from one of first battery pack 32 and second battery pack 36 to electric motor 42. In accordance with the present subject matter, parallel port 40 acts as an adapter, which controls and defines current flow to electric motor 42 from one of first battery pack 32 and second battery pack 36 to power electric motor 42. In other words, parallel port 40 connects to both first battery pack 32 and second battery pack 36, and receives and directs power output from whichever battery pack is acting as a primary battery source to operate electric motor 42. Power output from one of first battery pack 32 and second battery pack 36 delivers to parallel port 40, which in turn toggles drive shaft 20, directing flow f (FIG. 1) from appropriate battery to electric motor 42.

[0048] In accordance with one embodiment of the present subject matter, the battery pack powering electric motor 42 is referred as a primary battery source and the battery that is getting recharged while the other battery pack is powering electric motor 42 is referred as a secondary battery source. In other words, current toggle 28 engages two distinct but identical battery packs first battery pack 32 and second battery pack 36. The battery pack i.e., the primary battery source (say first battery pack 32) provides power to electric motor 42, and the secondary battery source (say second battery pack 36) gets recharged constantly by the return flow of kinetic energy created by the operation (output power) of the primary battery source. The primary battery source powers electric motor 42, which in turn creates distinct kinetic friction energy through the movement of mechanical/moving parts that gets captured by kinetic capture devices 22 thereby creating a loop for operating one of the battery packs for powering electric motor 42. A person skilled in the art understands that the presently disclosed power management system utilizes the kinetic energy, which otherwise gets lost from the movement of the moving parts in vehicle 14, and converts the kinetic energy to electric current for recharging the battery packs that power electric motor 42 whenever vehicle 14 is in motion.

[0049] Assuming that first battery pack 32 is fully charged and powering electric motor 42 from the charge stored therein, then first battery pack 32 becomes the primary battery source and second battery pack 36 becomes the secondary battery source as it gets charged until power in first battery pack 32 depletes to a pre-defined threshold level. Considering the above scenario, current toggle 28 directs the DC electric current to second battery pack 36 to recharge second battery pack 36 until the charge reaches 100% in second battery pack 36 or power in first battery pack 32 reaches near or below the pre-defined threshold level. If charge in second battery pack 36 reaches 100% while first battery pack 32 (acting as primary battery source) powers electric motor 42, then second power output flow governor 38 communicates to current toggle 28 such that current toggle 28 directs the DC electric current to third battery pack 44. Further, if charge in first battery pack 32 reaches near or below the pre-defined threshold level, then second power output flow governor 38 communicates to current toggle 28 such that current toggle 28 notifies parallel port 40 to change the battery output flow from first battery pack 32 to second battery pack 36, thus making second battery pack 36 the primary battery source and allowing first battery pack 32 to get charged and act as the secondary battery source.

[0050] After notifying, parallel port 40 allows and directs power output from second battery pack 36 to electric motor 42 to operate drive shaft 20 and thereby vehicle 14. Concurrently, current toggle 28 switches (as a return flow system) the flow of the DC electric current to charge first battery pack 32. The above process repeats when first battery pack 32 charges 100% or power in second battery pack 36 reaches near or below the pre-defined threshold level. Here, the power output flow governor in respective battery pack when acting as the primary battery source maintains a power output ceiling when the battery pack is powering electric motor 42. Critical to maximizing operational performance, respective power output flow governor manages battery power to effectively reach maximum, nearly unlimited drive range for vehicle 14 and uninterrupted operational time. Assuming a driver drives vehicle 14 maximum “flat out” at top power for long period of time, current toggle 28 and power output flow governors ensure maximum efficient power outflow is appropriate, so as not to cause early depletion of the primary battery source (before secondary battery source is fully recharged). The power output flow governor of the primary battery source ensures the battery power usage is sufficient to deliver the maximum power to electric motor 42 for the longest timeframe, thus enabling charging of the secondary battery source to gain full recharge time (and net extra DC electric current sent to third battery pack 44). The power output flow governor in respective battery pack operating as the primary battery source ensures vehicle 14 maintains plenty of acceleration capacity and torque to achieve normal speed and operational needs for the user, while recharging the battery packs in loop.

[0051] In the event of the primary battery source powering electric motor 42, and the secondary battery source has been fully recharged, the rollover option or rollover charge is engaged at current toggle 28. As a full efficiency operational capture and collection of the DC electrical current, current toggle 28 directs the incoming DC electrical current to third battery back 44.

[0052] Electric motor 42 operates from the power output of one of first battery pack 32 and second battery pack 36 and drives drive shaft 20. Drive shaft 20 operates and causes movement of the moving parts in vehicle 14 such as axle 16, drive shaft 20, braking, sensors (not shown), axle friction recharge, wheel rotation friction recharge, brake pad friction, exterior vehicle/mechanism friction capture, wind/water (hull friction, wake, etc.), solar surface on vehicle 14, etc. Movement of the moving parts causes kinetic energy release, re-capture, reprocess, redirection. As explained above, kinetic capture devices 22 are configured to capture the kinetic friction energy from axle 16, drive shaft 20, braking, sensors (not shown), axle friction recharge, wheel rotation friction recharge, brake pad friction, exterior vehicle/mechanism friction capture, wind/water (hull friction, wake, etc.), solar surface on vehicle 14, etc. Kinetic capture devices 22 capture the kinetic friction energy produced by movement of moving parts in vehicle 14, and transfer the kinetic friction energy via flow transfer cable(s) 23 to CDCSC 24. This constant power, constant kinetic friction energy capture, constant DC supercharge and recharge loop ensures the energy is conserved.

[0053] Power management system 12 includes third battery pack 44, as shown in FIGS. 1 and 5. Similar to first battery pack 32 and second battery pack 36, third battery pack 44 refers to multiple individual batteries contained within a single piece or multi-piece housing, the individual batteries electrically interconnected to achieve the desired voltage and capacity for a particular application. Third battery pack 44 acts as a distinct power collection hardware source or battery pack that accepts and stores the rollover charge or overflow charge, allowing transfer of stored electric charge to third battery pack 44 when vehicle 14 or power management system 12 is not in use. When first battery pack 32 powers electric motor 42 and second battery pack 36 has been fully charged and during all excess time beyond that moment (of no recharge need for second battery pack 36), and up to the defined depletion point (predefined threshold level) of first battery pack 32; then current toggle 28 rollovers the DC electric current (converted from the kinetic friction energy captured by kinetic capture devices 22) to third battery pack 44. Similarly, when second battery pack 36 powers electric motor 42 and first battery pack 32 has been fully charged and during all excess time beyond that moment (of no recharge need for first battery pack 32), and up to the defined depletion point of second battery pack 36; current toggle 28 rollovers the DC electric current (converted from the kinetic friction energy captured by kinetic capture devices 22) to third battery pack 44. Current toggle 28 directs the incoming DC electric current to third battery pack 44 to efficiently utilize the kinetic friction energy captured by kinetic capture devices 22.

[0054] In the present subject matter, third battery pack 44 collects and stores excess and unassigned DC electric current. In other words, third battery pack 44 fills to partial or full capacity (depending on operation time). Subsequently, third battery pack 44 transfers stored power to external battery pack 48 via transfer port 46. In one example, external battery pack 48 indicates a stand-alone home/industrial/grid battery power system that the user uses to power home appliances and other power equipment from the battery power stored therein. Transfer port 46 includes a universal connection adaptability that allows a “bidirectional” charging platform. Operationally, transfer port 46 receives excess charge or outputs charge and manages outbound transfer to external battery pack 48. In the event of both first battery pack 32 and second battery pack 36 deplete (due to possible system change or failure), third battery pack 44 can be used to power electric motor 42. Here, the battery charge from third battery pack 44 is directed to flow (via current toggle 28 and attending sensors) to parallel port 40 and thus directed to power electric motor 42 (from its internal stored electrical charge, if any).

[0055] FIGS. 6A and 6B show a perspective view and a top view of graphene sphere battery (GSB) or simply battery 100, respectively, in accordance with one embodiment of present subject matter. Each of first battery pack 32, second battery pack 36 and third battery pack 44 incorporates the design of battery 100. In one implementation, battery 100 has a unique concentric layered design e.g., sphere-shaped standalone structure. Battery 100 includes a spherical battery shell with concentric circles of ultrathin graphene sheet material attached to internal anchoring posts which hold the graphene material in place. As can be seen from FIG. 6B, battery 100 has thermophotovoltaic (TPV) sensor casing 102 that surrounds battery casing 104. Battery casing 104 includes multiple graphene sheets 106. Graphene sheets 106 are attached with the help of attachment posts 108 to retain them in shape. At the outer side, TPV sensor casing 102 includes battery ports 110 that supplies power to electric motor 42. Here, water or other superconducting fluid flows around and in between all independent or conjoined graphene sheets 106.

[0056] Battery 100 operates on a principle that the more conductive and reactive surface area that interacts with the reacting and catalyst fluid, the more maximized the resulting charge. When compared to existing lithium ion battery packs having a large pile of batteries taped or combined in a casing shell together, the presently disclosed battery 100 provides much more efficiency in increased charge and output potential, and significantly reduced gross weight and size of the on-board battery packages. As shown in FIGS. 6A and 6B, internal structure layout of graphene sheets 106 include alternately or independently concentric circles or spheres of independent graphene sheets 106 small to large in scope from the center at the battery anchor post to the outer battery casing 104. Alternatively, graphene sheets 106 include one extended, unbroken, expanding and encircling itself in a pinwheel formation from the center at the battery anchor post to the outer battery casing anchors, filling the battery casing as shown in FIG. 7 (another embodiment). The battery ports 110 maintain the integrity structure of spherical battery casing 104 and provide anchoring for graphene sheets 106. Battery port 110 includes a parallel port or separate ports (one for inflow, and another for outflow). Battery 100 optimizes inflow of recharge to the “secondary battery” position (second battery pack 36), and outflow of power capability for the “primary battery” (first battery pack 32). The super conducting capabilities of graphene sheets 106 and reactive fluid is superior to existing lithium ion battery packs.

[0057] FIG. 7 shows a top view of battery 150, in accordance with another embodiment of present subject matter. In the current embodiment, battery 150 includes a continuous or expanding “pinwheel structure”. Similar to battery 100, battery 150 has thermophotovoltaic (TPV) sensor casing 152 that surrounds battery casing 154. Battery casing 154 includes multiple graphene sheets 156. Graphene sheets 156 are attached with the help of attachment posts 158 to retain them in shape. At the outer side, TPV sensor casing 152 includes battery ports 110 that supplies power to electric motor 42. Here, water or other superconducting fluid flows around and in between all independent or conjoined graphene sheets 156.

[0058] FIG. 8 illustrates method 200 of operating a power management system for a battery-operated vehicle, in accordance with one exemplary embodiment of the present subject matter. The order in which method 200 is described should not be construed as a limitation, and any number of the described method blocks can be combined in any order to implement method 200 or alternate methods. Additionally, individual blocks may be deleted from method 200 without departing from the spirit and scope of the subject matter described herein. Furthermore, method 200 can be implemented in any suitable hardware, software, firmware, or combination thereof. However, for ease of explanation, in the embodiments described below, method 200 may be implemented using the above-described power management system 12.

[0059] As specified above, power management system 12 connects to vehicle 14 at axle and/or drive shaft 20. Power management system 12 operates when vehicle 14 is motion, as shown at step 202. Movement of vehicle 14 causes moving parts to produce kinetic friction energy. Kinetic capture devices 22 capture the kinetic friction energy produced by the moving parts, as shown at step 204. At step 206, kinetic capture devices 22 transfer the kinetic friction energy captured to central direct current (DC) supercharge component 24 (CDCSC) 24. At step 208, CDCSC 24 converts the kinetic friction energy to a DC electric current. CDCSC 24 connects to current toggle 28, whereby current toggle 28 directs the DC electric current to one of first battery pack 32, second battery pack 36, and third battery pack 44 (step 210).

[0060] At step 212, current toggle 28 checks whether first battery pack 32 and second battery pack 36 are fully charged. Considering that second battery pack 36 is fully charged (or has sufficient charge to power electric motor 42) and first battery pack 32 is depleted (below the predefined threshold level) or requires charging, then current toggle 28 directs the DC electric current to charge first battery pack 32 and uses second battery pack 36 as a primary battery source for operating electric motor 42 (step 214). At step 216, current toggle 28 checks with second power output flow governor 38 if second battery pack 36 is at or below a predefined threshold level charge. If second battery pack 36 has sufficient charge, then current toggle 28 in conjunction with second power output flow governor 38 instructs parallel port 40 to direct power flow f from second battery pack 36 to operate electric motor 42, as shown at step 218. If charge in second battery pack 36 is at or below a predefined threshold level charge (at step 216), then method 200 moves to step 120. At step 120, current toggle 28 directs the DC electric current to charge second battery pack 36 and uses first battery pack 36 as a primary battery source for operating electric motor 42. At step 222, current toggle 28 checks with first power output flow governor 34 if first battery pack 32 is at or below a predefined threshold level charge. If first battery pack 32 has sufficient charge, then current toggle 28 in conjunction with first power output flow governor 32 instructs parallel port 40 to direct power flow f from first battery pack 32 to operate electric motor 42, as shown at step 224. If charge in first battery pack 32 is at or below a predefined threshold level charge (at step 222), then method 200 moves back to step 214.

[0061] Upon powering electric motor 42 at steps 218 and 224, electric motor 42 drives drive shaft 20 which in turn operates moving parts in vehicle 12 to produce kinetic friction energy which gets captured by kinetic capture devices 22 at step 204. This creates a constant power supply loop for operating electric motor 42 from the power out of one of first battery pack 32 and second battery pack 36.

[0062] At the time of charging first battery pack 32 at step 214, current toggle 28 determines whether first battery pack 32 has fully charged while second battery pack 36 has sufficient charge to power electric motor 42 (step 226). If first battery pack 32 has fully charged while second battery pack 36 has sufficient charge to power electric motor 42, then current toggle 28 directs the DC electric current to charge third battery pack 44 (step 230). If not (step 226), then method 200 moves to step 216.

[0063] Similarly, at the time of charging second battery pack 36 at step 220, current toggle 28 determines whether second battery pack 36 has fully charged while first battery pack 32 has sufficient charge to power electric motor 42 (step 228). If second battery pack 36 has fully charged while first battery pack 32 has sufficient charge to power electric motor 42, then current toggle 28 directs the DC electric current to charge third battery pack 44 (step 230). If not (step 228), then method 200 moves to step 222. After charging third battery pack 44 at step 130, the battery power gets transferred to external battery pack 48, as shown at step 232.

[0064] Based on the above, a person skilled in the art understands that the presently disclosed power management system uses less energy as it requires no recharging from external sources, and delivers more efficient and constant operational function. This allows the vehicle to have constant, renewable, and uninterrupted power supply in both operational range and operational time to EVs and similar mechanically powered machinery and industrial systems, without the need for external plug-in recharging needs. The presently disclosed power management system allows for use the entire life span of battery packs and/or electric motor.

[0065] Further, under normal operating conditions, the presently disclosed power management system allows the battery-powered electric vehicles to have nearly unlimited range of travel (distance)—without interruption, or need for time consuming stops for “plugging in” for recharging. The presently disclosed power management system comes in-built in new battery-operated vehicles or retro-fits into current electric motor powered vehicles operating with conventional lithium or other market standard battery sources, removing need for downtime/offline recharging, and extending operational range and life exponentially.

[0066] Further, the presently disclosed power management system is adaptable and effective in multiple operational instances, including most vehicle types (land-, water-, and air-based), as well as military transport and deployment, industrial mechanical operations including resource extraction wellhead drilling, many industrial plant and refinery operations, water well management, municipal infrastructure and transportation, construction and demolition vehicles, extreme condition power generation, and exo-atmospheric scenarios.

[0067] As the presently disclosed power management system powers the vehicle upon movement of the moving parts, the power management system operates independently of all reasonable weather conditions, lack of sunlight, water, wind and with proper insulation, even in the vacuum of space.

[0068] The presently disclosed power management system provides a long sought need of energy efficiency, power management platform expansion, and control for most concepts. The presently disclosed power management system provides a power management and on-board recharge flow platform and energy efficiency needs.

[0069] The kinetic capture devices provides a unique kinetic energy capture/collection hardware design and makes kinetic energy capture/collection process efficiency and adaptability. With the proposed kinetic capture devices efficiency of energy transfer and transform functions increases considering the vehicular systems related to overall weight and structural dynamics. In addition, the kinetic capture devices provide an ability to integrate/utilize multiple sensor capture components (solar, TPV, wind, compression).

[0070] The presently disclosed power management system provides less hardware, less gross weight, and therefore less vehicular drag and less wasted system redundancies.
