Systems and methods for managing battery state of charge

Provided is an inverter power module. The 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. 种逆变器功率模块，该逆变器功率模块将来自电池的电力选择性地施加于永磁体(PM)电动机；以及将由PM电动机输出的电力选择性地提供给电池。开关在打开时防止电力从电池流向逆变器功率模块，并且在闭合时，使得逆变器功率模块和电池之间进行电力流动。调节模块基于车辆速度
