The battery module comprises a main battery, a voltage converter, an auxiliary device, a battery management unit and a first set of switching devices and a second set of switching devices. The main battery provides the electric power. The auxiliary device is used to store the electric power. The battery management unit controls the main battery and the auxiliary device to charge or discharge through a first set of switching devices and a second set of switching devices, respectively. When the battery module is charged by an external charger, the auxiliary device and the main battery are charged simultaneously. When the external charger stops to charge the battery module, the battery management unit controls the auxiliary device through the second set of switching devices to continuously charge the main battery through the voltage converter. |
