Abstract
A method for processing an asynchronous motor includes obtaining indication trigger information; and injecting, in response to the indication trigger information, a first current into a stator winding of the asynchronous motor, where the first current is for generating heat without a torque for the asynchronous motor, and the heat heats a battery pack through a heat exchanger.
