Title:
BATTERY CHARGING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/188225
Kind Code:
A1
Abstract:
A battery charging method and device, relating to the field of batteries. The battery charging method comprises: setting N groups of charging parameters for N charge cycles (101), the charging parameters comprising a pulse charging current, and N is an integer greater than or equal to 2; performing pulse charging of N charge cycles on a battery using the charging parameters till the voltage of the battery reaches a preset charging cutoff voltage (102), wherein the pulse charging current of the ith charge cycle is less than the pulse charging current of the (i-1)th charge cycle, i is an integer, and 2≤i≤N; and performing constant-voltage charging on the battery with the preset charging cutoff voltage till the charging current of the battery reaches a preset charging cutoff current (103). The battery charging method and device can increase the battery charging speed.
