Title:
CHARGING METHOD AND APPARATUS, AND COMPUTER DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/087889
Kind Code:
A1
Abstract:
The present application relates to a charging method and apparatus, and a computer device and a storage medium. The method comprises: during the process of charging a battery, acquiring a battery parameter; determining the current negative electrode potential of the battery according to the correlation between the battery parameter and a negative electrode potential; when the current negative electrode potential is less than a potential threshold value, reducing the charging current of the battery; and when the current negative electrode potential is greater than the potential threshold value, increasing the charging current of the battery, so that the negative electrode potential of the battery is within a range corresponding to the potential threshold value, wherein the battery parameter comprises at least one of a voltage, a capacity and an open-circuit voltage of the battery. In the present application, a negative electrode potential of a battery is acquired in real time by means of the correlation between a battery parameter and a negative electrode potential, thereby realizing real-time closed-loop prediction of a negative electrode potential; and the charging current of the battery is effectively controlled according to the obtained current negative electrode potential and a potential threshold value, thereby realizing dynamic closed-loop adjustment of a charging current, and achieving the purpose of safely and quickly charging the battery.
