The present disclosure provides a system for estimating battery power capacity. One or more controllers charge and discharge the traction battery after startup of the vehicle according to a power limit that is based on a polarization voltage describing an internal state of the traction battery and that is a function of: a polarization voltage present at a last deactivation of the vehicle; and a decay value having a time constant based on a state of charge of the traction battery and a temperature associated with the traction battery.
本公开提供了“用于估计电池电力容量的系统”。一个或多个控制器在车辆的启动之后根据电力极限对牵引电池进行充电和放电,所述电力极限是基于描述所述牵引电池的内部状态的极化电压并且是以下的函数:所述车辆的上一次停用时存在的极化电压,以及具有基于所述牵引电池的荷电状态和与所述牵引电池相关联的温度的时间常数的衰减值。
