Abstract
Circuit and method for heating first and second batteries. The heating circuit includes first and second switch units, first and second damping components, first and second current storage components, switching control module and energy storage component. The first battery, first damping and current storage components, energy storage component and first switch unit are connected in a first loop to constitute a first charging/discharging circuit. The second battery, second damping and current storage components, energy storage component and second switch unit are connected in a second loop to constitute a second charging/discharging circuit. When the energy storage component is charged/discharged, current in the second charging/discharging circuit is reverse to current in the first charging/discharging circuit. The switching control module controls the first and second switch units to switch on in alternate, so as to control electric energy to flow among the first battery, energy storage component and second battery.
