Abstract
Official abstract text for this publication.
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 transfer 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 transfer unit is configured to, after the switch unit is turned on and then turned off, start removing first energy from the first charge storage component and complete transferring the removed first energy to an energy storage component. The circuit for heating the battery is configured to heat the battery by at least discharging the battery.
