摘要：
A detection method and device for the configuration error of a battery nominal capacity is presented. The invention is involved in the battery management and control. Actual voltages of a battery at different times are measured and recorded when the battery is discharged. Actual voltages are compared with theory voltages, which are in the present discharge current, present configured nominal capacity, and at different times. Absolute errors are obtained by the comparison, and used to judge whether there is an error on the current configuration of the battery nominal capacity. If the method is used to detect the configuration of the battery nominal capacity, two problems can be prevented. One is the large calculation deviation of the battery residual capacity detection and the battery life forecasting, which is caused by the configuration error of the battery nominal capacity. The other is the influence to the charge and discharge of the battery and then the life of the battery, which is caused by that also.
摘要（中）：
提出了一种用于电池额定容量配置误差的检测方法和装置。 本发明涉及电池管理和控制。 当电池放电时，测量并记录不同时间的电池的实际电压。 将实际电压与理论电压进行比较，理论电压在当前的放电电流，配置的标称容量和不同的时间。 通过比较获得绝对误差，用于判断电池额定容量的当前配置是否有误差。 如果使用该方法来检测电池额定容量的配置，则可以防止两个问题。 一个是电池剩余容量检测和电池寿命预测的大计算偏差，这是由电池额定容量的配置误差引起的。 另一种是对电池的充放电和电池的寿命的影响，这也是由此引起的。
