Abstract

The invention provides a battery repairing method and device and a battery repairing system, and the method comprises the steps: a to-be-repaired battery is controlled to enter a constant-temperature environment at a preset temperature, wherein the preset temperature is higher than normal temperature; the charging and discharging equipment is controlled to execute a first charging and discharging process on the to-be-repaired battery until a preset number of times, and the first charging and discharging process comprises a charging process and a first discharging process which are executed in sequence; the charging and discharging equipment is controlled to execute a second charging and discharging process on the to-be-repaired battery till the preset number of times, and the second charging and discharging process comprises the charging process and the second discharging process which are executed in sequence; and the charging and discharging equipment is controlled to charge the to-be-repaired battery to a rated capacity according to a first preset multiplying power constant current. According to the repairing method, the self-discharge rate of the to-be-repaired battery is reduced, and the problem of high self-discharge rate of the battery in the prior art is solved.

Description

technical field [0001] The present application relates to the technical field of battery repair, and in particular, relates to a battery repair method, a repair device, a computer-readable storage medium, a processor, and a battery repair system. Background technique [0002] In the current production of batteries, the quality requirements of batteries are getting higher and higher. As a kind of energy storage unit, the battery's charge retention ability is very important. In the production of batteries, due to the influence of factors such as the environment, personnel operation, and incoming materials, there will be batteries that self-discharge too fast, which will affect the performance of the battery. This type of battery occupies a certain proportion in the production of the battery, which increases the production cost of the battery. [0003] The above information disclosed in the Background section is only to enhance the understanding of the background of the techno...
