Problems solved by technology

[0002] Now the wireless charging technology of electric vehicles is more and more widely used, but at present, electric vehicles can only be charged in places equipped with wired or wireless charging. With the increasing number of electric vehicles, for the car charging station The construction puts forward great requirements, but the construction of electric vehicle charging piles needs to occupy a lot of space, and the investment is relatively large
In addition, if an electric vehicle user needs to drive uninterruptedly for a long time, he must stop and charge before driving, and wait for the electric vehicle to be fully charged before driving on the road, which will greatly waste the user's time under certain usage conditions

Abstract

The invention discloses a wireless mutual-charging method and system between electric vehicles. The wireless mutual-charging system comprises a wireless electric energy emitting module, an electric energy reception module, a DC / AC module, an AC / DC module, a vehicle-mounted battery, and a vehicle-mounted charge-discharge controller which are arranged inside the electric vehicle; the vehicle-mounted battery is connected to the wireless electric energy emitting module through the DC / AC module and is connected to the electric energy reception module through the AC / DC module; and the vehicle-mounted charge-discharge controller is connected to the DC / AC module, the AC / DC module and the vehicle-mounted battery. The wireless mutual-charging method and system reduce demand quantity for charging piles, reduces electric loads of a power grid in peak hours and save charging time.

Description

technical field [0001] The invention relates to the field of wireless charging of electric vehicles, in particular to a method and system for wireless mutual charging between electric vehicles. Background technique [0002] Now the wireless charging technology of electric vehicles is more and more widely used, but at present, electric vehicles can only be charged in places equipped with wired or wireless charging.
