Abstract

Disclosed are an automobile, and a power battery pack equalization method and device, the method comprises the following steps: acquiring a high voltage inflection point of the charging curve of a battery cell of the power battery pack and acquiring the capacity of the battery cell according to the high voltage inflection point of the battery cell, and equalizing the battery cell according to the capacity of the battery cell. Hence, equalization management of the power battery pack can be realized, thereby improving the use ratio of the power battery pack and prolonging the service life of the power battery pack.
