Description

technical field [0001] The invention relates to the application field of electric vehicle wireless power transmission, in particular to a wireless power transmission system from commercial power to a vehicle battery pack and a control method thereof. Background technique [0002] The traditional electric vehicle charging system relies on wired cables to realize the charging process from the mains to the vehicle power battery pack. However, this method cannot realize automatic charging, which violates the convenience requirements of electric vehicle users. At the same time, the charging process will cause high-voltage electric shock hazards to the operator. . Wireless energy transmission technology can just solve the above problems. A pair of magnetic energy transmitting and receiving modules are used instead of traditional wired cables to convert electrical energy into magnetic energy, then receive and convert it into electrical energy, and then charge it into the power batt...
