A plurality of camera 315 disposed on a top surface 102 of the platform 100b. In the preferred embodiment, four cameras 315a-d is disposed on four corners of the top surface 102 of the platform 100b, as shown in FIG. 7A. The four cameras 315a-d provide a view angle of 120 degree. The four cameras 315a-d are connected to the screen 105 to provide a live stream of video. The user aligns the platform 100b along the battery bay 750 of the vehicle 700 using the plurality of alignment markers 310. Further, the lifting mechanism 40b employed in the platform 100b includes each of the pair of arms 50 connected to a link through a shaft. Each link is further connected to a hydraulic cylinder, which in turn is connected to a hydraulic pump via a flow control valves. As per the present invention and common pump and/or separate valves may be utilized for LHS and RHS rams. This entire setup is powered by a power pack. Each of the pair of arms 50 is toggled between the upper configuration 42 and the downward configuration 44 by the user using control panel 110. This allows the user to either raise the battery 600 towards or away from the battery bay 750 of the vehicle 700. A current sensor 53 are incorporated into each of the pair of arms 50 for sensing engagement and/or disengagement of each of the pin 58 with each of the pair of slots 610 as a result of a change in flow of current as a function of weight. Also, each wheel 30 is powered by a servo-motor 31 allowing the platform 100b to move around by pressing a button 111 provided on the control panel 110 by the user.

[0052] In another embodiment, referring to FIG. 9A-9B, the platform 100c is operated by a user. The platform 100c includes a handle 120 attached the rod 115; a plurality of mirror 320 disposed on the platform 100c; and a pump handle 125 attached to the platform 100c. The rod 115 is attached to the platform 100c through its first end and the handle 120 is attached at a second end of the rod 115b.

Further, the lifting mechanism 40c employed in the platform 100c includes a pair of arms 50 connected to a link through a shaft. Each link is further connected to a hydraulic cylinder in turn connected a common pipe. Further, the common pipe is connected to a hand pump 125. A movement of the hand-pump 125 by the user allows each of the pair of arms 50 to be toggled between the upper configuration 42 and the downward configuration 44. This allows the user to either raise the battery 600 either towards or away from the battery bay 750 of the vehicle 700. The mirrors 320 provided on the platform 100c allow the user to visualize the plurality of alignment markers 310 disposed at various positions on a bottom chassis 760 for alignment of the platform 100c along the battery bay 750 of the vehicle 700.

[0053] According to FIG. 9, a method 2000 of swapping discharged battery 600 with charged battery 600 by the system 500 is outlined in FIG. 10. The method 2000 broadly includes a step of removal of a discharged battery from a vehicle 700 and a step of insertion of a fully recharged battery 600 into the vehicle 700 using the system 500. The method of removal of the discharged battery 600 from the vehicle 700 using the system 500 further includes recognizing and navigating a platform 100 to the vehicle 700; aligning of the platform 100 with a battery bay 750 of the vehicle 700 using a plurality of alignment markers 310; positioning the discharged battery 600a from the battery bay 750 to a rectangular hollow region 22 of the platform 100 using a lifting mechanism 40. The method of insertion of a fully recharged battery 600 into the vehicle 700 further includes recognizing and navigating of a platform 100 having a battery 600 i.e. a fully charged to the vehicle 700; aligning of the platform 100 with the bottom chassis 760a of the vehicle 700 using the plurality of alignment marker 310; lifting of the battery 600 i.e. the fully charged from the platform 100 towards the battery bay 750 using the lifting mechanism 40; securing of the battery 600 into the battery bay 750 of the vehicle 700.

[0054] The method 2000 initiates when the vehicle 700 arrives at a station. The vehicle 700 is identified using either a car registration number and/or a battery serial number (step 2002). The platform 100 is empty. The platform 100 navigates to the vehicle 700 (step 2004). Further, the platform 100 aligns itself under the vehicle 700 by identifying a plurality of alignment markers 310 disposed on a bottom chassis 760 of the vehicle 700. This allows the alignment of the platform 100 with a battery bay 750 of the vehicle 700 (step 2006). Each of two pair of arms 50 provided on an inner first wall 12 and inner second wall 13of the platform 100 attain an upward configuration 42 using a lifting mechanism 40 (step 2008). The upward configuration 42 of the two pair of arms 50 leads engagement of each of the pin 58 with each of slot 610 on a battery 600 (step 2010). Thus, the step 2006 of the alignment of the platform 100 with the battery bay 750 the vehicle 700 forms a crucial step in the method 2000 for the exchange of the battery 600 i.e. a discharged battery using the system 500. Following the step 2010, the battery 600 i.e. the discharged battery is removed from the battery bay 750 of the vehicle 700 (step 2012). Thus, the battery 600 released from the battery bay 750 and remains engaged and supported by the pair of arms 50 in the upward configuration 42. The battery 600 i.e. the discharged battery is placed into a rectangular hollow region 22 having a depth d of the platform 100. This is achieved by toggling of the pair of arms 50 along with the battery 600 i.e. the discharged battery from an upward configuration 42 to a downward configuration 44 using the lifting mechanism 40 (step 2014). The platform 100 along with the battery 600 i.e. the discharged battery moves away from the vehicle 700 for a placement of the battery 600 i.e. the discharged battery to a storage system where the battery 600 i.e. the discharged battery is placed for recharging (step 2016).

[0055] A second platform 100 or the same platform 100 identifies and navigates to the vehicle 700 (step 2018). The second platform 100 or the same platform 100 carries battery 600 i.e. a fully charged battery placed in a rectangular hollow region 22 having a depth d of the platform 100. The battery 600 is placed such that a pair of slots 610 is engaged with each pin 58 of each of the pair of arms 50 in the downward configuration 44 of the second platform 100. The step 2018 is followed with alignment of the second platform 100 or the same platform 100 with the battery bay 750 of the vehicle 700 by identification of a plurality of alignment markers 310 (step 2020). The step 2020 is followed with the lifting of the battery 600 i.e. the fully charged battery from the second platform 100 or the same platform 100 towards the battery bay 750. The lifting of the battery 600 i.e. the fully charged battery from the rectangular hollow region 22 of the second platform 100 or the same platform 100 is achieved by a movement of each of the pair of arms 50 from the downward configuration 44 to the upward configuration 42 using the lifting mechanism 40 (step 2022). The step 2022 is followed by mounting of battery 600 i.e. the fully charged battery with the battery bay 750 of the vehicle 700 (step 2024). This completes the process of placement of the fully charged battery module 600 into the battery bay 750 of the vehicle 700. The second platform 100 or the same platform 100 moves away from the vehicle 700.

[0056] In a preferred embodiment, a method 2000a of swapping depleted battery 600 with recharged battery 600of a vehicle 700 using an autonomous or automatic platform 100a includes the following steps as explained below. The autonomous platform is powered by a power pack to carry out all its functions as mentioned below. When the vehicle 700 arrives at a station, a unique code of the vehicle 700 is transmitted through a central server 300 of a battery swapping system 500 to the platform 100a. The unique code includes a car registration number and/or a battery serial number. This step is followed by navigation of the platform 100a to the vehicle 700 using the unique code by a positioning system. During the navigation to the vehicle 700, the platform 100a maneuvers itself using a power pack. Further, the plurality of wheels 30 are provided with servo-motor powered by a power pack for self-maneuvering of the platform 100a. The platform 100a maneuvers using a plurality of ultrasonic proximity sensors 320 for detection of hurdles in the path to the vehicle 700. This is followed by the step of alignment of the platform 100a by detecting a plurality of alignment marker 310 under the vehicle 700. A plurality of camera 315 disposed on the platform 100a are programmed to automatically detect of the plurality of alignment marker 310, thus aligning the platform 100a along the battery bay 750 of the vehicle 700. The precise alignment of the platform 100a is followed by toggling of each of two pair of arms 50 to attain an upward configuration 42 using a lifting mechanism 40. The lifting mechanism 40 implemented is a worm gear and a spur gear attached to a servo motor. Further, a microcontroller is attached to the servo motor powered by a power pack. The microcontroller based on a signal moves each of the pair of arms 50 synchronously towards the battery bay 750 of the vehicle 700. This leads to the engagement of each pin 58 of each of the pair of arms 50 with each of the pair of slots 610 of the battery 600 i.e. the discharged battery. Each of the pair of arms 50 is provided with an encoder. The encoder 51 is able to determine position of arms 50, and weight is sensed by means of current consumption of servo motor detecting the completion of the engagement of each pin 58 of each of the pair of arms 50 with each of the pair of slots 610 of the battery 600 i.e. the discharged battery. This allows the system 500 to carry the step of removal of the battery 600 i.e. the discharged battery from the battery bay 750. This step is followed by the step of placement of the battery 600 i.e. the discharged battery into a rectangular hollow region 22 having a depth d of the platform 100a. This step is achieved by the toggling of each of the pair of arms 50 along with the battery 600 i.e. the discharged battery from the upward configuration 42 to the downward configuration 44 using the lifting mechanism 40. Following the above step, the platform 100a along with the battery 600 i.e. the discharged battery moves away from the vehicle 700 for a placement of the battery 600 i.e. the discharged battery to a storage system where the battery 600 i.e. the discharged battery is placed for charging.

[0057] A second platform 100a or the same platform 100a with a battery 600 i.e. a charged battery identifies and navigates to the vehicle 700 by the unique code using the positioning system 400 and the plurality of ultrasonic proximity sensors 320 to the vehicle 700. This is followed by the step of alignment of the second platform 100a or the same platform 100a along the battery bay 750 of the vehicle 700. This step includes the platform 100a or 100a automatically detecting the plurality of alignment marker 310 using the plurality of camera 315 under the vehicle 700 for a precise alignment. This step is followed by the step of lifting the battery 600 i.e. fully charged from the depth d of the platform 100a towards the battery bay 750 of the vehicle 700. In this step, each of pin 58 of each of the pair of arms 50 are engaged with each of the pair of slots 610. This step is followed by the step of mounting the battery 600 fully charged with the battery bay 750 of the vehicle 700. In this step once the battery 600 i.e. fully charged is mounted into the battery bay, each of the pair of arms 50 are toggled from the upward configuration 42 to the downward configuration 44. This step occurs only when the encoder provided in each of the pair of arms 50 detects a zero weight. In the next step, the platform 100a moves away from the vehicle 700.

[0058] In another embodiment, a method 2000b of swapping depleted battery 600 with recharged battery 600 of a vehicle 700 using a semi-automatic platform 100b includes the following steps as explained below. When the vehicle 700 arrives at a station, a unique code of the vehicle 700 provided to a user having the platform 100b. The unique code includes a car registration number and/or a battery serial number. This step is followed by navigation of the platform 100b by the user to the vehicle 700 using the unique code. The plurality of wheels 30 are provided with servomotor powered by a power pack for maneuvering of the platform 100b under the control of the user. This is followed by the step of alignment of the platform 100b by detecting a plurality of alignment markers 310 under the vehicle 700. A plurality of camera 315 disposed on the platform 100b provides a live stream on a screen 105 having a control panel 110. This helps the user to align the platform 100b manually, thus aligning the platform 100a along the battery bay 750 of the vehicle 700. The precise alignment of the platform 100b by the user is followed by the user toggling of each of two pair of arms 50 to attain an upward configuration 42 using a lifting mechanism 40 using the control panel 110. The lifting mechanism 40b implemented includes a pair of arms 50 connected to a link through a shaft. Each link is further connected to a hydraulic cylinder in turn connected a common pipe and powered by a power pack. The user using the control panel 110 moves each of the pair of arms 50 to attain an upward configuration 42. This leads to the engagement of each pin 58 of each of the pair of arms 50 with each of the pair of slots 610 of the battery 600 i.e. the discharged battery. Each of the pair of arms 50 is provided with a current sensor. The current sensor is able to detect the change in the current in each of the arms 50, detecting the completion of the engagement of each pin 58 of each of the pair of arms 50 with each of the pair of slots 610 of the battery 600 i.e. the discharged battery. This allows the system 500 to carry the step of removal of the battery 600 i.e. the discharged battery from the battery bay 750. This step is followed by the step of placement of the battery 600 i.e. the discharged battery into a rectangular hollow region 22 having a depth d of the platform 100a. This step is achieved by the toggling of each of the pair of arms 50 along with the battery 600 i.e. the discharged battery from the upward configuration 42 to the downward configuration 44 using the lifting mechanism 40. Following the above step, the platform 100b along with the battery 600 i.e. the discharged battery moves away from the vehicle 700 for a placement of the battery 600 i.e. the discharged battery to a storage system where the battery 600 i.e. the discharged battery is placed for charging.

[0059] A second platform 100a or the same platform 100a with a battery 600 i.e. a charged battery is navigated by the user to the vehicle 700 using the unique code. This is followed by the step of alignment of the second platform 100a or the same platform 100a along the battery bay 750 of the vehicle 700 by the user. This step includes the user visualizing the plurality of alignment markers 310 on the screen 105 using the plurality of camera 315 under the vehicle 700 for a precise alignment with the battery bay 750. This step is followed by the step of lifting the battery 600 i.e. fully charged from the depth d of the platform 100a towards the battery bay 750 of the vehicle 700 by the user. In this step, each of pin 58 of each of the pair of arms 50 are engaged with each of the pair of slots 610. This step is followed by the step of mounting the battery 600 fully charged with the battery bay 750 of the vehicle 700. In this step once the battery 600 i.e. fully charged is mounted into the battery bay, each of the pair of arms 50 are toggled from the upward configuration 42 to the downward configuration 44. This step occurs only when the current sensors provided in each of the pair of arms 50 sense zero current. In the next step, the platform 100a moves away from the vehicle 700.

[0060] In other embodiment, a method 2000c of swapping depleted battery 600 with recharged battery 600 of a vehicle 700 using a manual platform 100c includes the following steps similar to that of the method 2000b. In the step of navigation of the platform 100c to the vehicle 700, the user pushes the platform 100c. Further, in the step of alignment of the platform 100c with the battery bay 750 of the vehicle 700, the user uses the plurality of mirrors 320 provided on the platform 100c for detecting positions of the alignment markers 310 for a precise alignment of the platform 100c. Further, the platform 100c implements a lifting mechanism 40b similar to the platform 100b. A hand pump replaces the power pack in the semi-automatic platform for toggling the pair of arms 50. The user has to move the hand pump in an up and down motion for toggling of each of the pair of arms 50 from an upward configuration 42 to a downward configuration 44 and vice versa for removal or mounting of the battery 600 or 600 into the vehicle 700. Further, the user uses the plurality of mirrors 320 for determining the engagement of each of the pins 58 of each of the pair of arms 50 with each of the pair of slots 610 of the battery 600 or 600.
