Abstract
A heating method traction battery. The traction battery is connected to a switch circuit of a motor and configured to supply power to the motor via the switch circuit. The switch circuit includes multiple legs and the multiple legs are connected to the traction battery in parallel. The method includes: receiving a heating signal sent by a battery management system of the traction battery; and controlling, according to the heating signal, at least one of the multiple legs to form a short-circuit loop of the traction battery, the short-circuit loop being configured to discharge the traction battery and heat the traction battery during the discharging process.
