Abstract: A battery formation apparatus includes a DC-DC conversion module, an additional power supply, and a control circuit. Low-voltage and high-voltage terminals of the DC-DC conversion module are electrically connected to the control circuit and a DC bus, respectively. The DC-DC conversion module is configured to, when a battery unit discharges into the battery formation apparatus, convert a first voltage input into a second voltage greater than the first voltage, and output the second voltage. The additional power supply is electrically connected to the control circuit, and configured to output an additional voltage. The control circuit is electrically connected to the battery unit, the low-voltage terminal of the DC-DC conversion module, and the additional power supply. The control circuit is configured to serially connect the low-voltage terminal of the DC-DC conversion module, the battery unit, and the additional power supply when the battery unit discharges into the battery formation apparatus.
