Abstract

The invention discloses a wireless charging system and method for an electric vehicle. The wireless charging system comprises a ground power supply device and a vehicle-mounted charging device, and the ground power supply device comprises a primary side monitoring coil unit, a primary side power coil unit, a first micro-control unit and a power transmission controller; the first micro-control unit is used for monitoring the circuit state of the power transmission controller and controlling the primary side monitoring coil unit to output wireless power when the circuit state of the power transmission controller is not abnormal; the vehicle-mounted charging device comprises a secondary side monitoring coil unit, a secondary side power coil unit, a second micro-control unit and a power receiving controller, and the second micro-control unit receives the electric energy output by the primary side monitoring coil unit through the secondary side monitoring coil unit, so that power is supplied to a vehicle control system of the electric vehicle through the power receiving controller. According to the wireless charging system and method provided by the invention, the low-power wireless charging device is used for power supply and safety protection of the control circuit of the high-power wireless charging device.

Description

technical field [0001] The invention relates to the technical field of wireless charging for electric vehicles, in particular to a wireless charging system and method for electric vehicles. Background technique [0002] As an important way to accelerate energy transition and realize low-carbon economy, electric vehicles have attracted more and more countries' attention. The electrification of automobiles is an inevitable trend of future development. However, the charging of electric vehicles has always been one of the key issues restricting the development of electric vehicles. At present, the wired charging mode is widely used for electric vehicle charging. The wired charging method is prone to sparks; rainy and snowy weather is prone to leakage and short circuit; after years of wear and tear, the charging wire is easily exposed, bent, and poor contact during the charging process. In the wired charging process of electric vehicles, if the above problems occur, the chargin...
