Abstract
Official abstract text for this publication.
A circuit for heating a battery includes a switch unit, switching control module, damping component, energy storage circuit, and freewheeling circuit. The energy storage circuit is connected with the battery, and includes a current storage component and charge storage component. The damping component, switch unit, current storage component, and charge storage component are connected in series. The switching control module is connected with the switch unit, and is configured to control switching on and off of the switch unit so that current can flow back-and-forth between the battery and energy storage circuit when the switch unit switches on, and amplitude of the current flowing from the energy storage circuit to the battery can be controlled. The freewheeling circuit is configured to sustain the current flowing to the battery when there is current flowing from the energy storage circuit to the battery and after the switch unit switches off.
