GE863-PRO3Hardware User Guide

Last but not least, in some applications it is highly desired that the charging process restarts when the battery is discharged and its voltage drops below a certain threshold, GE863-PRO3internal charger does it.

As you can see, the charging process is not a trivial task to be done; moreover all these operations should start only if battery temperature is inside a charging range, usually 5°C - 45°C.

The GE863-PRO3measures the temperature of its internal component, in order to satisfy this last requirement, it's not exactly the same as the battery temperature but in common application the two temperature should not differ too much and the charging temperature range should be guaranteed.

NOTE: For all the threshold voltages, inside the GE863-PRO3all thresholds are fixed in order to maximize Li-Ion battery performances and do not need to be changed.

NOTE: In this application the battery charger input current must be limited to less than 400mA. This can be done by using a current limited wall adapter as the power source.

NOTE: When starting the charger from Module powered off the startup will be in CFUN4; to activate the normal mode a command AT+CFUN=1 has to be provided. This is also possible using the POWER ON. There is also the possibility to activate the normal mode using the ON/OFF* signal.

In this case, when HW powering off the module with the same line (ON/OFF*) and having the charger still connected, the module will go back to CFUN4.
