Abstract
A method for determining a battery capacity, includes: acquiring a first inflection voltage, a first inflection electric power, a second inflection voltage, and a second inflection electric power of the battery, charging the battery and recording a first charging profile of the battery; determining a target inflection point of the battery according to the first charging profile; detecting the electric power until the charging is completed, acquiring a first charged electric power of the battery when the battery is charged to a first inflection point, and acquiring a second charged electric power of the battery when the charging is completed; and when the target inflection point includes the first inflection point, calculating a current capacity of the battery according to the first inflection electric power, the first charged electric power, and the second charged electric power. The first inflection voltage is greater than the second inflection voltage.
