Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0028] As mentioned in the background art above, in the existing fast charging method, during the process of fast charging the battery, the aging of the battery is accelerated due to improper selection of the charging rate. The reason is that the existing fast charging method adopts the ladder current method, that is, the initial charge rate is used for charging for a period of time, and then the rate is lowered in turn to enter the subsequent step platform to charge the battery with the recharge rate corresponding...

Abstract

The invention discloses a battery quick charging method, device and equipment and a storage medium. The method comprises the following steps: determining a mapping relation table between the state ofcharge of a battery and the maximum charging rate; obtaining the actual state of charge of the battery; determining the maximum charging rate of the battery in the current state according to the actual state of charge of the battery and the mapping relation table of the state of charge of the battery and the maximum charging rate; and selecting the maximum charging rate of the battery in the current state to charge the battery. According to the technical scheme provided by the embodiment of the invention, the aging speed of the battery is reduced on the basis of improving the charging speed ofthe battery.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery fast charging method, device, equipment and storage medium. Background technique [0002] During the use of the battery, when the power of the battery is low, it can be charged quickly to restore the power of the battery, thereby continuing to provide power for the device to be powered. [0003] In the existing fast charging method, in the process of fast charging the battery, the accelerated aging of the battery is caused due to improper selection of the charging rate. Contents of the invention [0004] In view of this, the embodiments of the present invention provide a battery fast charging method, device, equipment, and storage medium, which reduce the aging speed of the battery on the basis of increasing the charging speed of the battery. [0005] An embodiment of the present invention provides a battery fast charging method, including: [0006] Determine the ...
