METHOD AND APPARATUS FOR CALCULATING SOH OF BATTERY POWER PACK, AND ELECTRIC VEHICLE

Provided is a method for calculating the SOH of a battery power pack. The method comprises the following steps: acquiring a charging curve of a cell of a battery power pack, and determining a current charging phase according to the charging curve, wherein the charging phase comprises a high voltage charging inflection point and a high voltage charging phase (S); acquiring a battery pack power amount corresponding to the high voltage charging inflection point and a battery pack power amount corresponding to the high voltage charging phase (S); calculating the remaining capacity of a cell according to the battery pack power amount corresponding to the high voltage charging inflection point and the battery pack power amount corresponding to the high voltage charging phase (S); and calculating the SOH of the cell according to the remaining capacity (S).
