A high-voltage battery assembly includes a high-voltage battery electrically connected to a high-voltage bus including a positive rail and a negative rail, wherein the negative rail includes a controllable contactor switch. A boost charging module includes a DC-DC boost converter, a low-voltage power input line, a boost switch and a boost controller. The DC-DC boost converter is electrically connected to the low-voltage power input line via activation of the boost switch. The DC-DC boost converter connects to the positive rail. A low-voltage electrical connector is electrically connected to the low-voltage power input line of the DC-DC boost converter. The boost controller detects low-voltage power from the low-voltage electrical connector, detects that the controllable contactor switch, closes the boost switch, and controls the DC-DC boost converter to convert the low-voltage power on the low-voltage power input line to high-voltage power to charge the high-voltage battery. 种高压电池组件包括高压电池，所述高压电池电连接到包括正轨和负轨的高压
