Wireless charging system and method for electric vehicle to electric vehicle

Abstract

The invention discloses a wireless charging system for electric cars and a control method of the wireless charging system. The system comprises an electric energy providing device, an electric energy receiving device and a battery management device, wherein the battery management device comprises a first battery manager and a second battery manager, and the electric energy providing device is used for transmitting electric energy to the electric energy receiving device; the electric energy receiving device uses the electric energy provided by the electric energy providing device to charge a second power battery; the first battery manager is used for controlling the wireless charging flow of the electric energy providing device; the second battery manager is used for controlling the wireless charging flow of the electric energy receiving device. The wireless charging system has the advantages that wireless charging between the electric cars can be achieved, high safety and reliability are achieved, charging is simple and practicable, the service life of charging equipment can be prolonged by the wireless charging manner, and high applicability is achieved.

Description

technical field [0001] The invention relates to the technical field of power battery charging for electric vehicles, in particular to a wireless charging system and method for electric vehicles to electric vehicles. Background technique [0002] With the continuous promotion of new energy vehicles, especially electric vehicles or hybrid vehicles, new energy vehicles have become increasingly relevant to our daily life. Due to the impact of battery power on current electric vehicles, the cruising range is limited and it is difficult to meet the travel needs of users. Especially when the user's driving vehicle has run out of power during driving, the electric vehicle cannot continue to drive, which affects the user's itinerary. [0003] Based on the above problems, one electric vehicle can be used to charge another electric vehicle, so that the electric vehicle with low power can obtain a certain amount of power, so that it can be driven to a nearby charging station for chargi...

AI Technical Summary

Problems solved by technology

[0004] First of all, the moving and handling of the charging equipment and the lead wires of the high-voltage harness are too long, and the manual operation is cumbersome

Most of the existing connected devices use wired connections, and the connected devices need to be plugged and unplugged every time they are charged.

[0005] Secondly, due to manual operation, factors such as excessive wear and unsafety of the charging connection equipment are prone to occur during the charging process

There will be wear and tear when the connecting device is plugged in, and there are exposed high-voltage components, which will have a certain impact on the safety and reliability of the charging system and shorten the service life of the charging device
