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.
