Abstract:
1. A circuit for heating a battery, the circuit comprising: the battery including a first damping component parasitic to the battery; a switch unit; a switching control component coupled to the switch unit; a first one-way semiconductor component; and a transformer including a first winding and a second winding; wherein the circuit for heating the battery is configured to heat the battery by at least discharging the battery with a discharging current flowing through at least the first damping component, the first winding of the transformer, and the switch unit; wherein the circuit for heating the battery is further configured to heat the battery by at least charging the battery with a charging current flowing through at least the second winding of the transformer, the first one-way semiconductor component, and the first damping component.
