| description | The invention relates to a method for rapidly obtaining the total capacity of a battery pack. The method comprises the following steps: S1, obtaining target battery reference curve data and battery nominal capacity Capinitial; S2, processing the battery reference curve data, and recording the capacity or charging capacity of the battery at the characteristic value position; S3, calculating a relation coefficient of the capacity and the total capacity between the battery characteristic values; S4, processing the charging curve of the battery pack, and recording the charging capacity of the battery at the characteristic value position; and S5, calculating the capacities among the battery characteristic values obtained in step S4, and calculating the capacities of all the single batteries of the battery pack one by one according to the relationship coefficient in step S3. The method is suitable for the normal charging process of the battery pack, the working input and output of the battery are not influenced, on |
