Title:
BATTERY CHARGING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/176693
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), N being an integer greater than or equal to 2; performing pulse charge of N charge cycles on a battery by using the charging parameters until the voltage of the battery reaches a preset charge cutoff voltage (102), the power obtained during pulse charge in the (i-1)th charge cycle being greater than the power obtained during pulse charge in the ith charge cycle, wherein i is an integer, and 2≤i≤N; and performing constant voltage charge on the battery using the preset charge cutoff voltage until the charging current of the battery reaches a preset charge cut-off current (103). The battery charging method and device can improve the charging speed of a battery.
