Abstract
Circuit and method for heating a battery. The circuit includes the battery including a first damping component and a first current storage component, a switch unit, a switching control component, a first charge storage component, and an energy superposition unit. The switching control component is configured to turn on the switch unit so as to allow a current to flow between the battery and the first charge storage component and to turn off the switch unit so as to stop the current. The energy superposition unit is configured to, after the switch unit is turned on and then turned off, adjust a storage voltage associated with the first charge storage component so that a positive voltage terminal of the first charge storage component is coupled, directly or indirectly, to a negative voltage terminal of the battery.
