Abstract:
1. A heating circuit for a battery comprising a first battery and a second battery, the heating circuit comprising a first switch unit, a second switch unit, a first damping component, a second damping component, a first current storage component, a second current storage component, a switching control module and a charge storage component, wherein: the first battery, the first damping component, the first current storage component, the first switch unit and the charge storage component are connected in a first loop to form a first charging/discharging circuit; the second battery, the second damping component, the second current storage component, the charge storage component and the 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, a direction of a charging/discharging current in the second charging/discharging circuit is reverse to a direction of a charging/discharging current in the first charging/discharging circuit; the switching control module is electrically connected with the first switch unit and the second switch unit, and the switching control module is configured to control the first switch unit and the second switch unit to switch on in alternate, so as to control electric energy flow among the first battery, the charge storage component and the second battery.
