Patent ID: 10742044

Abstract:
Disclosed are equalization control method, apparatus and circuit for a power battery. The equalization control method includes: detecting a to-be-equalized cell in the power battery satisfying a preset equalization starting condition, and starting to perform an equalization on the to-be-equalized cell; in a process of performing the equalization on the to-be-equalized cell, determining whether the to-be-equalized cell satisfies an equalization stopping condition; when it is determined that the to-be-equalized cell satisfies the equalization stopping condition, stopping performing the equalization on the to-be-equalized cell, and when the to-be-equalized cell satisfies an equalization continuing condition, continuing to perform the equalization on the to-be-equalized cell; and when it is determined that the to-be-equalized cell does not satisfy the equalization stopping condition, continuing performing the equalization on the to-be-equalized cell, and finishing the equalization until the time period during which the equalization is performed on the to-be-equalized cell satisfies the equalization time calculated value.
