Abstract: An inverter power module: selectively applies power from a battery to a permanent magnet (PM) electric motor; and selectively provides power output by the PM electric motor for the battery. A switch, when open, prevents power flow the inverter power module from the battery, and, when closed, enables power flow between the inverter power module and the battery. An adjustment module determines an SOC adjustment based on at least one of a vehicle speed and a temperature of the battery. A maximum module receives a first maximum SOC of the battery and that determines a second maximum SOC of the battery based on the first maximum SOC and the SOC adjustment. A clutch control module disengages a clutch, decoupling the PM electric motor from a transmission, when the switch is stuck closed and an SOC of the battery is greater than the second maximum SOC.

Abstract: 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.
