Abstract

The invention relates to a battery charging method and device and a storage medium. The battery charging method comprises the steps that in the stage charging process of the battery, the current static voltage of the battery is acquired in the current charging stage, and the maximum charging current matched with the current static voltage is determined; and charging the battery according to the maximum charging current. According to the invention, the charging speed can be guaranteed, overvoltage protection can be ensured not to be triggered in each charging stage, and the battery cell is prevented from being damaged.

Description

technical field [0001] The present disclosure relates to the technical field of charging, in particular to a battery charging method, device and storage medium. Background technique [0002] In the era of intelligence, electronic products have entered every aspect of human life. The convenience brought by electronic products has made people more and more dependent on them, which has led to people gradually increasing their requirements for the performance of batteries in electronic products. Large capacity, endurance and safety have become important factors for evaluating battery performance. factor. For this reason, in the updating of electronic products in the past, manufacturers tend to make certain improvements to the battery. [0003] At present, when charging electronic products, the increase of current will cause battery overvoltage protection, which will directly lead to battery cell damage, and even cause safety accidents in severe cases. [0004] In this regard,...
