The invention provides motorized vehicle control using multi-cell state estimation. A system includes a traction battery and a controller. The traction battery includes a first array and a second array of battery cells. The controller is programmed to implement a first filter and a second filter, such as a first bar-delta filter and a second bar-delta filter, the filters configured to generate outputs indicative of a state of charge (SOC) of the first array and the second array, respectively, from models of the first array and the second array. The controller is further programmed to charge and/or discharge the traction battery according to a power limit defined by the SOCs of the first array and the second array.
本公开提供了“使用多电池单元状态估计的电动化车辆控制”。一种系统包括牵引电池和控制器。所述牵引电池包括电池单元的第一阵列和第二阵列。所述控制器被编程为实现第一滤波器和第二滤波器,诸如第一条形‑Δ滤波器和第二条形‑Δ滤波器,所述滤波器被配置成分别从所述第一阵列和所述第二阵列的模型生成指示所述第一阵列和所述第二阵列的荷电状态(SOC)的输出。所述控制器还被编程为根据由所述第一阵列和所述第二阵列的所述SOC限定的电力极限对所述牵引电池进行充电和/或放电。
