The end of charging control is needed in order to prevent the battery from overcharge, when the battery is full, some special information can be used to judge whether the charge is at the end.
There are six ways to prevent the battery from being over-charged.:
1 peak voltage control: by detecting the peak voltage of the battery to determine the end of the charge;
2 dT/dt control: by detecting the battery peak temperature change rate to determine the end of the charge;
3 T control: when the battery is filled, the temperature and the temperature of the environment will reach the maximum;
4 -V control: when the battery is full of electricity to reach a peak voltage, the voltage will fall to a certain value
5 time control: by setting a certain charge time to control the charging terminal, the general set to charge into the 130% nominal capacity of the time required to control;
6 TCO control: consider the safety and characteristics of the battery should avoid high temperature (except for high temperature battery) charge, so when the battery temperature rise to 60 OC should stop charging.
