Abstract
Circuit and method for heating a battery. The heating circuit includes a switch unit, a switching control module, a one-way semiconductor component, a damping component and a transformer. The switching control module is electrically connected with the switch unit. The battery, the damping component, a first winding of the transformer, and the switch unit are connected in a first loop with each other to constitute a battery discharging circuit. The battery, the damping component, a second winding of the transformer, and the one-way semiconductor component are connected in a second loop with each other to constitute a battery charging circuit.
