BATTERY REMAINING CHARGING TIME ESTIMATION METHOD AND APPARATUS, AND BATTERY MANAGEMENT SYSTEM

WIPO Patent Application WO/2022/205228

A1

The present application provides a battery remaining charging time estimation method and apparatus, and a battery management system. The method comprises: on the basis of a required charging current value of each type of battery cell in a K-th charging stage, determining the minimum charging time of each type of battery cell in the K-th charging stage; and when the K-th charging stage of any type of battery cell in a battery is a target charging stage, determining the remaining charging time of the battery, the remaining charging time of the battery being the smallest cumulative value among cumulative values of the minimum charging time of each type of battery cell in the battery in respective charging stages. In this way, the remaining charging time of a battery containing a plurality of types of battery cells can be estimated. In addition, in the present application, estimation is carried out in stages, and the effect of temperature changes on the calculation of the remaining charging time is also considered, thereby further improving estimation accuracy of the remaining charging time for batteries containing multiple types of battery cells.
