Title:
QUICK CHARGING METHOD FOR BATTERY, CHARGING DEVICE, DEVICE TO BE CHARGED AND CHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/062127
Kind Code:
A1
Abstract:
Provided by the present application are a quick charging method for a battery, a charging device, a device to be charged and a charging system. The quick charging method for the battery comprises: acquiring status parameters of a battery in a device to be charged, wherein the status parameters of the battery comprise the present temperature of the battery; selecting a charging cutoff voltage corresponding to the current temperature from a target parameter mapping relationship, wherein the charging cutoff voltage is greater than the rated voltage of the battery; and charging the battery at a constant current until the voltage of the battery reaches the charging cut-off voltage, and then stopping charging of the battery, which may thus increase the time of constant current charging at a high current, thereby effectively increasing the charging speed. In addition, the cut-off voltage for charging is flexibly adjusted by means of the temperature of the battery, which prevents the battery from overvoltage damage and ensures that the battery is at full capacity.
