Abstract:
Under one aspect, a heating circuit for at least a first battery and a second battery includes a first charging/discharging circuit, which is connected to the first battery, and a second charging/discharging circuit, which is connected to the second battery. The first charging/discharging circuit includes a first damping component, a first current storage component, a first switch unit, and a charge storage component, all of which are connected in a first loop with each other. The second charging/discharging circuit includes a second damping component, a second current storage component, a second switch unit, and the charge storage component, all of which are connected in a second loop with each other.
