The present invention provides a system and method for hybrid-electric vehicle battery capacity estimation. An electrified vehicle includes a powertrain that includes an engine and an electric machine. The vehicle includes a traction battery that is charged and discharged by the operation of the engine and the electric machined. The vehicle includes a controller programmed to operate the engine and the electric machine to satisfy a driver power demand. The controller is also programmed to initiate an estimated of a capacity of the traction battery under predetermined conditions. The controller operates the engine and the electric machine to satisfy the driver power demand and charge and discharge the traction battery in a predetermined manner to create conditions favorable for estimating the capacity.

    本公开提供“用于混合动力电动车辆电池容量估计的系统和方法”。一种电动化车辆包括动力传动系统,所述动力传动系统包括发动机和电机。所述车辆包括牵引电池,所述牵引电池通过所述发动机和所述电机的操作而充电和放电。所述车辆包括控制器,所述控制器被编程为操作所述发动机和所述电机以满足驾驶员功率需求。所述控制器还被编程为在预定条件下发起对所述牵引电池的容量的估计。所述控制器操作所述发动机和所述电机以满足所述驾驶员功率需求并以预定方式对所述牵引电池充电和放电以创建有利于估计所述容量的条件。
