    摘要： A vehicle can include a traction battery and a controller in communication with the battery to determine the battery state using sensed battery electrode capacity to account for battery aging. The sensed battery electrode capacity can be dependent on active lithium ions at a positive electrode of the traction battery. The controller can compare a battery voltage model to measured battery voltage during a vehicle drive cycle, receive sensed current though put data and open circuit voltage at the battery, and determine if a deviation threshold is exceeded. The controller can also correct electrode capacity using a mean of the measured open-circuit voltage to correct the capacity error to less than one amp-hour or initiate an active lithium capacity correction using a variance of the current throughput to correct the capacity error to less than one amp-hour. This information can be used to control the vehicle and battery usage.

    摘要翻译： 车辆可以包括牵引电池和与电池通信的控制器，以使用感测的电池电极容量来确定电池状态以解决电池老化。 感测到的电池电极容量可以取决于牵引电池的正电极处的活性锂离子。 控制器可以在车辆驱动循环期间将电池电压模型与测量的电池电压进行比较，通过放置数据接收感应电流和电池处的开路电压，并确定是否超过偏差阈值。 控制器还可以使用测量的开路电压的平均值来校正电极容量，以将容量误差校正为小于1安培小时，或者使用当前吞吐量的方差来启动活动锂容量校正，以将容量误差校正为更小 超过一个安培小时。 该信息可用于控制车辆和电池的使用。
