More Information
Summary:The invention provides lithium plating detection and mitigation in electric vehicle batteries. A vehicle includes a traction battery and a controller. The controller is programmed to, in response to dynamic resistance and capacity of the traction battery for a drive cycle differing from dynamic resistance and capacity of the traction battery for a previous drive cycle by threshold percentages, controlling the traction battery to reduce lithium plating. 本公开提供了"电动车辆电池中的析锂检测和缓解"。一种车辆包括牵引电池和控制器。所述控制器被编程为响应于在某一驾驶循环内所述牵引电池的动态电阻和容量与在先前驾驶循环内所述牵引电池的动态电阻和容量相差了阈值百分比，控制所述牵引电池以减少析锂。
