(98) The control switch 18 is a 12V/24V selective type switch as shown in
(99) The rear side of the control switch 18 is shown in
(100) The second embodiment of the battery jump starting device 110 is shown in
(101) In the second embodiment of the battery jump starting device 110 (
(102) The battery jump starting device 110 comprises a pair of 12V Li-ion batteries 132 directly connected to the highly conductive rigid frame 170. Specifically, terminals 132a, 132b (e.g. highly conductive bars of copper or aluminum) of the Li-ion batteries are mechanically connected and/or soldered to the positive and negative tabs or foils, respectively, of the battery cells and then connected to the highly conductive rigid frame 170 by highly conductive fasteners 206 comprising a bolt 206a and nut 206b and/or soldering.
(103) The highly conductive rigid frame 170 is constructed of multiple highly conductive rigid frame members 170a-h connected together by mechanical fasteners (e.g. metal nut and/or bolt fasteners) and/or soldering. For example, the highly conductive rigid frame members are made of highly conductive rigid metal rods having flattened ends with through holes. Alternatively, the highly conductive rigid metal rods can be replaced with highly conductive rigid metal plates, bars, tubing, or other suitably configured highly conductive metal material (e.g. copper or aluminum stock material). The highly conductive rigid frame members 170a-h can also be insulated (e.g. covered with heat shrink insulation) in at least the key areas to prevent any internal short circuiting.
(104) The highly conductive rigid frame members 170a-h shown in
(105) For example, the reverse flow diode assembly 148 is constructed of three (3) base portions of three (3) highly conductive frame members 170d, 170e, 170f of the highly conductive rigid frame 170, including: 1) an upper highly conductive rigid bar 148a (
(106) As another example, the smart switch 150 (
(107) The stock material (e.g. copper or aluminum rod, plate, bar, tubing) selected for construction of the highly conductive rigid frame 170 has substantial gauge to provide high conductivity and substantial rigidity. The “rigid” nature of the highly conductive rigid frame 170 provides the advantage that the highly conductive rigid frame 170 remains structurally stiff and stable during storage and use of the battery jump starting device 110.
(108) For example, the highly conductive rigid frame 170 is designed and constructed to sufficiently prevent flexing, movement, bending and/or displacement of the highly conductive rigid frame 170 during storage or use so as to prevent electrical shortages of the highly conductive rigid frame touching other internal electrical components or parts of the electronic assembly. This “rigid” nature is important due to the high conductivity path of electrical power from the Li-ion batteries 132 flowing through the power circuit and reaching the battery clamps 60, 62 (
(109) As an alternative, the highly conductive rigid frame 170 can be constructed as a single piece having no mechanically fastened joints. For example, the highly conductive rigid frame 170 can be made from a single piece of stock material and then formed, bent, machined, or manufactured into the highly conductive rigid frame 170. For example, a billet of highly conductive copper can be machined (e.g. milled, lathed, drilled) into the highly conductive rigid frame 170. As another example, a copper sheet or plate can be bent and/or machined into the highly conductive rigid frame 170. As a further alternative, the highly conductive rigid frame 170 can be metal molded (e.g. loss wax process).
(110) As another alternative, the highly conductive rigid frame 170 is made of multiple highly conductive rigid frame members 170a-h connected together into a unitary structure. For example, the highly conductive rigid frame 170 is made of highly conductive sections of stock material (e.g. copper or aluminum rod, plate, bar, tubing), which are extruded, machined and/or bent, and soldered and/or welded together.
(111) The battery jump starting device 110 further comprises a resistor array 202 (e.g. 12 V 5 A XGC) comprising a printed circuit board (PCB) 202a serving as a base supporting an array of individual resistors 202b, as shown in
(112) The left side of the battery jump starting device 110 is also fitted with a pair of light emitting diodes 128 (LEDS) for using the battery jump starting device 110 as a work light. For example, the LEDs 128 are dual 1100 Lumen high-intensity LED floodlights), as shown in
(113) The battery jump starting device 110 is fitted with a heat sink 129 (
(114) The battery jump starting device 110 is shown in

(116) A third embodiment of the battery jump starting device 210 is shown in
(117) Further, the battery jump starting device 210 comprises a main printed circuit board 208 serving as a base for LEDs for the control knob 218a and interface 216, and for supporting other electrical components of the battery jump starting device 210.

The receptacle 27ba is configured to accommodate the pin 27aa and tooth 27ab of the male cam-lock end 27a. Specifically, the pin 27aa and tooth 27ab of the male cam-lock end 27a can be inserted (
(123) The male cam-lock end 27a is fitted with a rubber molded cover 31, as shown in
(124) The assembly of the male cam-lock 27a is shown in
(125) The copper sleeve 41 is fitted into the receptacle 27ad of the male cam-lock end 27a, as shown in

(127) The rubber molded cover 31 is provided with one or more inwardly extending protrusions 31a cooperating with one or more slots 27ae in an outer surface of the male cam-lock end 27a (
(128) Again, the male cam-lock end 27a and the female cam-lock end 27b are configured so as to tighten together when rotating the male cam-lock end 27a when inserted within the female cam-lock end 27b.

Electrical Control Switch Backlight System
(133) The battery jump charging device 10 can be provided with an electrical control switch backlight system 200, as shown in
(134) The electrical control switch backlight system 200, for example, comprises control switch 18 having the control knob 18a, the interface 16 (e.g. membrane label), and the main printed circuit board 208.
(135) The control knob 18a is made of plastic (e.g. injection molded plastic part). For example, the control knob 18a is mainly made of a colored opaque plastic material selected to prevent the transmission of light therethrough provided with a clear plastic slot 18b molded therein (e.g. insert molded). The clear plastic slot 18b serves as a light window to allow light from one or more backlight LEDs mounted on the printed circuit board 208 to pass through the interface 16 and the light window when the power button 17 of the interface 16 is turned on (e.g. touch power switch) lighting the one or more LEDs. Alternatively, the clear plastic slot 18b can be replaced with an open slot in the control knob 18b serving as the light window.
(136) The control switch 18 is rotatable between a first position (Position 1) for a 12V mode of operation of the battery jump starting device 10 and a second position (Position 2) for a 24V mode of operation of the battery jump starting device 10. The power is shown “on” in
(137) The interface 16 is provided with a 12V backlight indicator 16a, a 24V backlight indicator 16b, a 12V backlight indicator 16c, a 24V backlight indicator 16d, a variable display backlight indicator 16e for indicating the actual operating voltage of the battery jump charging device 10, and a power “on” indicator 16f, as shown in
(138) The electrical control switch backlight system 200 can be configured to turn on white LEDs mounted on the printed circuit board 208 when the control switch 18 is located at Position 1 for the 12V mode of operation of the battery jump starting device 10, and turn on blue LEDs mounted on the printed circuit board 208 when the control switch 18 is located at Position 2 for the 24V mode of operation of the battery jump starting device 10. As show in
Electrical Optical Position Sensing Switch System
(139) The portable jump starting device 10 can be configured as a dual purpose Li-ion jump starter to allow for jump starting either a 12V or 24V heavy duty vehicle or piece of equipment. This lightweight portable unit utilizes the manual rotary control switch 18 with the control knob 18a for switching between 12V or 24V jump starting or operational modes. Any of the above described portable jump starting devices according to the present invention can be provided with the electrical optical position sensing system 300, as shown in
(140) The portable jump starting device 10 uses two 12V Li-ion batteries that are connected in parallel for 12V jumpstarting and in series for 24V jump starting. The series or parallel connections are accomplished with the rotary control switch 18 (e.g. Master Switch), as shown in
(141) The electrical optical position sensing system 300 is shown in
(142) A schematic of the circuit of the optical position sensing system 300 is shown in
(143) If Q27 is “on”, it allows current to flow from Battery A+ to Battery B− when the batteries are connected in parallel. When they are connected in series, no current flows because A+ and B− are connected together through the control switch 18.
(144) The result of current flow or lack thereof, allows the optical coupler to provide a signal to the microcontroller telling it which position the Master Switch is in.
(145) The second portion of the schematic (i.e. schematic located just below the first schematic), allows the opposite signal to be provided to a separate input of the microcontroller. The result of this is to provide the microcontroller an effective method of determining when the switch is “In Between” meaning it is not in 12V position or 24V position and is in between those two positions. This allows the microcontroller to provide diagnostics in case a user leaves the switch in an unusable position.

Leapfrog Charging System
(151) The battery jump starting devices 10, 110, and 310 use two (2) 12V lithium batteries used for jumpstarting vehicles and other system functions. These two individual batteries are used in both series or parallel depending on whether the operator is jumpstarting a 12V vehicle or a 24V vehicle.
(152) The battery jump starting device 10, 110, 310 can be charged using a charging device having a plug-in cord (e.g. 114 V to 126 V (RMS) AC charger) and charging control device (e.g. programmable micro-controller). Each battery is charged on its own by the battery jump starting device 10, 110, 310 separate from the other battery, but the batteries are kept close in potential during the charging process using a technique called “leapfrog charging”. This charging approach insures that both batteries are close to the same potential even if the battery jump starting device 10, 110, 310 is removed from charging early. This provides for equal power delivery during jumpstarts as well as other system functions.
(153) The battery jump starting device 310 is provided with a charging device. For example, the circuit board 408 shown in
(154) This method is accomplished by charging one Li-ion battery 332, starting with the lowest charged battery, until it is approximately 100 mv higher than the other battery 332, and then switching to charge the other battery 332. This process continues until both batteries 332 are completely charged.
(155) Safeguards are provided in the battery jump starting device 310 to protect against any of the batteries 332 being overcharged as well as sensing if a battery cell is shorted. These safeguards include peak voltage shutoff as well as charge timeouts in software.
(156) The leapfrog charging system and method can be design or configured to charge the rechargeable batteries 332 (e.g. Li-ion batteries) in a charging sequence. The charging sequence can be designed or configured to ensure that both batteries become fully charge regardless of the operations of the battery jump starting device 310. In this manner, the batteries are fully charged on a regular basis to maximize the use and life of the batteries.
(157) Further, the charging sequence can be tailored to most effectively charge particular types of rechargeable battery, in particular Li-ion batteries taking into account particular charging properties of the batteries (e.g. reduce heat generation of batteries over a time interval, apply best charging rate(s) for batteries, charging in a sequence increase life of batteries. The charging sequence, for example, can be to partially charge the batteries 332, one at a time, and back-and-forth. For example, the charging sequence can be configured to incrementally charge the batteries 332 in a back-and-forth sequence until both batteries are fully charged. For example, a voltage increase increment can be selected (e.g. 100 mV) for charging the batteries in a back-and-forth sequence.
(158) In addition, the charging sequencing between the two batteries 332 can be selected or programmed to provide back-to-back charging of one battery two or more increments before switching to the other battery for charging. Also, the charging sequence can include one or more pauses to prevent the charging battery 332 from becoming too hot (e.g. temperature limit) or so that the charging sequence matches with the charging chemistry of the charging battery.

(159) The highly electrically conductive frame 370 (“highly conductive frame”), is shown in
(160) The highly conductive frame 370 can replace the electrically conductive cables 34, 36, 40, 42, 44, 46, 52, 54 (
(161) The highly conductive frame 370 comprises a positive conductive frame 371a and negative conductive frame 371b, as shown in
(162) The highly electrically conductive frame 370 comprises the multiple electrically conductive frame members 370a-h electrically and mechanically connected together. For example, the highly electrically conductive frame members 370a-h are each provided with connecting ends having through holes 371 to allow a fastener (e.g. highly electrically conductive nuts and bolts) to connect the electrically conductive frame members 370a-h to each other or to other electrical components (e.g. rechargeable batteries 332, cam-locks 324a, 324b, back-charge diode module 348, smart switch 450). The highly electrically frame members 370a-h, for example, are flat highly electrically conductive bars (e.g. copper or aluminum bars) bent along multiple spaced apart axes to provide a three dimensionally (3D) arrangement of each highly electrically conductive bar 370a-h, which cooperate together to define a three dimensional (3D) highly electrically conductive frame 370. As shown in
(163) The highly electrically conductive frame 370, for example, can be a highly electrically conductive semi-rigid or rigid frame 370 made of semi-rigid or rigid highly conductive material (e.g. copper, aluminum, plated metal, gold plated metal, silver plated metal, steel, coated steel, stainless steel). The highly electrically conductive frame 370 is structurally stable (i.e. does not move or flex) so that it does not contact and electrically short with components or parts of the portable jump starting device. The more rigid the highly electrically conductive frame 370 typically the more structurally stable is the highly electrically conductive frame 370.
(164) The highly electrically conductive frame 370 electrically connects together the two (2) batteries 332, for example Li-ion batteries 332 with the cam-locks 324a, 324b. The cam-locks 324a, 324b connect to the removable or detachable positive and negative battery cables 56, 58 (
