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 charge storage component. The first battery, first damping and current storage components, first switch unit and charge storage component are connected in a first loop to form a first charging/discharging circuit. The second battery, second damping and current storage components, charge storage component and second switch unit are connected in a second loop to form a second charging/discharging circuit. When the charge storage component is charged or discharges, charging/discharging current in the second charging/discharging circuit is reverse to that 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 flow among the first battery, charge storage component and second battery.
