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. |
