When the electric vehicle 4 needs to be charged, the charge controller controls the telescopic mechanism to extend and retract so that the power supply device is connected to the power receiving device in a lap joint mode, and then the charging cabinet is started so that the power supply of the charging cabinet is transmitted into the power supply of the electric vehicle 4 through the power supply device and the power receiving device. Compared with the prior art, the embodiment avoids the insertion of the charging gun, the power supply device can be automatically overlapped on the power receiving device under the driving of the telescopic mechanism, and the charging of the electric vehicle 4 is completed under the condition that the charging cabinet is started.

Further, the power receiving device is provided on the roof of the electric vehicle 4. The power transmission device is arranged above the power receiving device. After the telescopic mechanism extends, the power supply device is driven to be lapped on the power receiving device. After the telescopic mechanism contracts, the power supply device is driven to leave the power receiving device, and charging is finished.

Further, the system also comprises an input device and a central controller. The input device is used for sending a charging instruction to the central controller. The central controller sends a charging instruction to the charging controller after receiving the charging instruction, and the charging controller controls the telescopic mechanism to extend after receiving the charging instruction so that the electricity supply device is connected to the electricity receiving device in an overlapping mode. The central controller is also used for controlling the starting and the shutdown of the charging cabinet. After the power service device and the power receiving device are successfully lapped, the central controller controls the charging cabinet to be started, controls the charging main loop to be conducted, and starts to charge the electric vehicle 4.

Further, the telescopic mechanism includes: a suspension 14, a first transmission arm 11, a second transmission arm 12, a tie rod 13 and a drive device. Wherein the first end of the first transmission arm 11 is articulated on the suspension 14. The first end of the pull rod 13 is also articulated on the suspension 14. A second end of the pull rod 13 and a second end of the first transmission arm 11 are both hinged on a first end of the second transmission arm 12. The second end of the second transmission arm 12 can be hinged to the power supply device. The driving device is controlled by the charging controller. The driving device is used to drive the swing of the first transmission arm 11. Referring to fig. 1, when the driving device drives the first transmission arm 11 to rotate clockwise, the pull rod 13 rotates clockwise along with the first transmission arm 11. The second transmission arm 12 rotates counterclockwise around the first end of the second transmission arm 12, and the second transmission arm 12 rotates from a horizontal state to a vertical state, so the second end of the second transmission arm 12 drives the power feeding device to extend downward, and finally overlaps with the power receiving device. After the charging is finished, the driving device drives the first transmission arm 11 to rotate anticlockwise, and the pull rod 13 rotates anticlockwise along with the first transmission. The second transmission arm 12 rotates clockwise around the first end of the second transmission arm 12, the second transmission arm 12 rotates from the vertical state to the horizontal state, and then the second end of the second transmission arm 12 drives the power supply device to contract, and finally the reset is completed.

The terms "clockwise" and "counterclockwise" are used in the present application with reference to the drawings, and are only for convenience of understanding of the embodiments, and do not limit the extension and contraction mechanism to extend when the first transmission arm 11 rotates clockwise and contract when the first transmission arm 11 rotates counterclockwise, but to illustrate that the extension and contraction mechanism extends when the first transmission arm 11 rotates in one direction and contracts when the first transmission arm rotates in the other direction.

Further, a rotating arm 15 is included. The pivot arm 15 is rotatably provided on the suspension 14. The first end of the first transmission arm 11 is connected to the pivot arm 15. The driving means is for driving the normal rotation and reverse rotation of the rotating arm 15.

One end of the spring return device is hinged to the swivel arm 15 and the other end is hinged to the suspension 14. After the spring driving device 17 pushes the rotating arm 15 to rotate, the spring returning device will pull the rotating arm 15 back to the original position.

In order to reduce the space occupied by the telescopic mechanism, the spring drive means 17 and the spring return means may be arranged on the same side of the swivel arm 15. The piston of the telescopic cylinder 16 extends to compress the spring driving device 17, the spring driving device 17 can push the rotating arm 15 to rotate, the spring resetting device is stretched, and the rotating arm 15 can drive the first transmission arm 11 to swing clockwise, so that the extension of the telescopic mechanism is realized, and the charging is realized. After the charging is finished, the piston of the telescopic cylinder 16 contracts to release the compression force of the spring driving device 17, so that the rotating arm 15 rotates to the original position under the driving of the spring resetting device, the rotating arm 15 drives the first transmission arm 11 to swing anticlockwise in the resetting process, the contraction of the telescopic mechanism is realized, the power supply device is separated from the power receiving device, and the charging is finished.

Further, a proximity switch may also be provided. After the proximity switch detects that the telescopic mechanism is contracted in place, a contraction stopping command is sent to the charging controller, so that the charging controller controls the driving device to stop. In particular, a base may be provided below the swivel arm 15, with one end of the spring drive 17 hinged to the base. A proximity switch is arranged above the base and used for sensing the base. When the spring return device pulls the rotating arm 15 to return, the base rotates along with the rotating arm 15. When the proximity switch detects the base, the telescopic mechanism is contracted to the position, and then the proximity switch sends a contraction stopping instruction to the charging controller, so that the charging controller controls the driving device to stop.

The second temperature sensor is used to detect the charging temperature between the first direct current positive electrode plate 27 and the second direct current positive electrode plate. The first temperature sensor sends the detected first temperature value to the charge controller. The second temperature sensor sends the detected second temperature value to the charge controller. If the charging controller judges that the first temperature value or the second temperature value exceeds the set temperature value, the charging is abnormal, and the charging controller sends a charging stopping signal to the central controller.
