The invention relates to electrified vehicle energy management for robust cold power discharge capability. A vehicle has an engine, a battery, and an electric machine configured to propel the vehicleand selectively coupled to the engine to start the engine and includes a controller configured to prompt for input to activate a cold weather mode in response to an expected ambient temperature to bebelow a first temperature threshold for a time period during which a subsequent engine start is anticipated, and to operate the engine and electric machine to maintain a state of charge (SOC) of the battery above a first SOC threshold in response to activation of the cold weather mode, and a second SOC threshold lower than the first SOC threshold otherwise.
本公开提供“用于稳健的冷电力放电能力的电动化车辆能量管理”。一种车辆具有发动机、电池和电机,所述电机被配置为推进所述车辆并选择性地联接到所述发动机以起动所述发动机,所述车辆包括控制器,所述控制器被配置为:响应于在预期后续发动机起动的时间段内预计的环境温度低于第一温度阈值而提示进行输入以激活冷天气模式;以及响应于所述冷天气模式的激活而操作所述发动机和所述电机以将所述电池的荷电状态(SOC)维持在高于第一SOC阈值,否则维持在高于第二SOC阈值,所述第二SOC阈值低于所述第一SOC阈值。
