Abstract:
1. A heating circuit for at least a first battery and a second battery, wherein the heating circuit comprises: a first charging/discharging circuit, which is connected to the first battery, and comprises a first damping component, a first current storage component, a first switch unit, and a first charge storage component, all of which are connected in a first loop with each other; and a second charging/discharging circuit, which is connected to the second battery, and comprises a second damping component, a second current storage component, a second switch unit, and the first charge storage component, all of which are connected in a second loop with each other, wherein the first switch unit comprises a first one-way branch configured to transfer energy from the first battery to the first charging/discharging circuit and a second one-way branch configured to transfer energy from the first charging/discharging circuit to the first battery and/or wherein the second switch unit comprises a third one-way branch configured to transfer energy from the second battery to the second charging/discharging circuit and a fourth one-way branch configured to transfer energy from the second charging/discharging unit to the second battery; and wherein the first switch unit comprises a first two-way switch and a second two-way switch, which are connected in series opposite to each other to form the first one-way branch and the second one-way branch and/or wherein the second switch unit comprises a third two-way switch and a fourth two-way switch, which are connected in series opposite to each other to form the third one-way branch and the fourth one-way branch.
