Abstract
Official abstract text for this publication.
A circuit for heating a battery includes the battery including parasitic damping and current storage components, a switch unit, a switching control component coupled to the switch unit, a charge storage component, and a freewheeling circuit. The charge storage component and current storage component are at least parts of an energy storage circuit. The damping component, the current storage component, the switch unit, and the charge storage component are connected. The switching control component is configured to turn on and off the switch unit so as to control a first current flowing from the battery to the charge storage component and a second current flowing from the charge storage component to the battery. The freewheeling circuit is configured to allow a freewheeling current to flow to the battery after the switch unit is turned off. The circuit for heating the battery is configured to heat the battery by at least discharging and charging the battery.
