What are the control methods to prevent battery overcharging?

In order to prevent the battery from being overcharged, it is necessary to control the charging end point. When the battery is full, there will be some special information that can be used to judge whether the charging has reached the end point. Generally, there are six ways to prevent the battery from being overcharged: 01) Peak voltage Control: Determine the end of charging by testing the peak voltage of the battery; 02) dT/dt control: Determine the end of charging by testing the peak temperature change rate of the battery; 03) △T control: When the battery is fully charged, the temperature is between the temperature and the ambient temperature. The difference will reach the maximum; 04) -△V control: When the battery is fully charged and reaches a peak voltage, the voltage will drop a certain value; Statement: Some pictures and content of the articles published on this site are from the Internet.
