Abstract

A method and apparatus for cooling a vehicle-mounted wireless charging device, and an electronic device and a vehicle. By means of acquiring current vehicle operation information which is associated with ambient noise of a target vehicle, then determining a target input voltage duty cycle of a cooling device on the basis of the current vehicle operation information, and controlling, on the basis of the target input voltage duty cycle, the cooling device to cool a vehicle-mounted wireless charging device so as to cover cooling noise of the cooling device by means of the ambient noise during vehicle operation, the cooling device can be controlled to operate with a relatively high input voltage duty cycle when the ambient noise of the vehicle is high, and the cooling device can be controlled to operate with a relatively low input voltage duty cycle when the ambient noise of the vehicle is low, so that a user's perception of the noise of the cooling device is reduced by means of the ambient noise of the vehicle, and disturbances to the user that are caused by the noise of the cooling device are thus reduced, thereby resolving the charging speed of a vehicle-mounted wireless charging device, and also solving the problem of the noise of a cooling device.
