Claim 14:
15. The method according to claim 14, wherein controlling the low-voltage terminal of the DC-DC conversion module, the battery unit, and the additional power supply of the battery formation apparatus to be serially connected in response to detecting that the output voltage of the battery unit is less than the voltage threshold comprises:
in response to detecting that the output voltage of the battery unit is less than the voltage threshold, after stopping an AC-DC conversion module of the battery formation apparatus, controlling the low-voltage terminal of the DC-DC conversion module, the battery unit, and the additional power supply of the battery formation apparatus to be serially connected; and
after controlling the low-voltage terminal of the DC-DC conversion module, the battery unit, and the additional power supply of the battery formation apparatus to be serially connected, restarting the AC-DC conversion module.
