Abstract

The charging method of the battery comprises the following steps that in the mth charging and discharging cycle, constant-current charging is conducted on the battery with a charging current, and m isany two or more integers of 1, 2, 3,..., x; wherein a first state of charge SOC1 of the battery when the constant current charging stage in any charge-discharge cycle is cut off is the same as a standard state of charge SOC0 (S21); SOCb is smaller than or equal to SOC0 and smaller than or equal to SOCa+k, SOCa is the state of charge or the preset value of the battery when the constant-current charging stage is cut off in the nth charging and discharging cycle, and SOCb is the state of charge or the preset value of the battery when the constant-current charging stage is cut off in the m1th charging and discharging cycle. By adopting the charging method of the battery, the full charging time of the battery can be shortened, the overcharging phenomenon of the battery can be avoided, and theservice life of the battery can be prolonged.

Description

technical field

[0001] The present application relates to the field of battery technology, and in particular to a battery charging method, an electronic device, and a storage medium. Background technique

[0002] At present, the commonly used charging method for lithium-ion batteries is to continuously charge the lithium-ion battery to a certain voltage (which can be understood as the charging limit voltage) through a preset constant current, and then charge the lithium-ion battery with a constant voltage at this voltage to full capacity. charging state. In this case, as the number of charging cycles and the use time of the battery increase, the impedance of the battery increases, which will shorten the time of constant current charging and prolong the time of constant voltage charging of the battery, resulting in the total charging time of the battery longer and longer. Contents of the invention

[0003] In view of this, it is necessary to provide a charging method, an ...
