The invention discloses a system and method for electric vehicle wireless charging. A lifting device and a charging coil sliding rail are arranged on a wireless charging emission device, a controller on the wireless charging emission device controls the lifting device to move and position on the charging coil sliding rail, and the position of the lifting device is determined according to the curve chart of the conversion rate of received power and transmitted power, so that alignment of a transmitting coil and a receiving coil is achieved. According to the system and method, by means of the technical means of wireless charging, transmission of energy between a transmitting device and a receiving device is achieved, contact and exposure of parts are avoided so that the durability and service life of charging parts can be improved, and the safety of charging is improved; according to the curve chart of the conversion rate of the received power of the receiving coil and the output power of the charging coil, the controller determines the final position of the lifting device, then alignment of the charging coil and the receiving coil is achieved through rotation of the chainwheel of the charging coil, and automatic control is achieved through minimum operation.
Description
technical field [0001] The invention relates to the battery charging field of a wireless charging electric vehicle or a hybrid electric vehicle, in particular to a system and method for wireless charging of an electric vehicle. Background technique [0002] In recent years, with the problems of energy consumption and environmental pollution, due to the development of science and technology, the technology of electric vehicles and hybrid electric vehicles is developing rapidly. With the increase of electric vehicles, how to better charge electric vehicles to users It brings various bad experiences. In the existing technology, wired charging piles or wireless charging piles are generally used to charge electric vehicles. Compared with wired charging piles, wireless charging piles improve charging by limiting the contact and exposure of components. Durability and longevity of components, increased safety by hiding potentially dangerous circuits and connection interfaces, and in...
