Hi,
Supposing you have a 16Ah 12 cell LiPO battery.
Supposing we charge it up to 47V (3.91V/cell)
We will simply charge it with constant current of 13A up to 47V, then keep it at 47V (Our charger is current limited to 13A).
When it reaches 47V, a comparator simply disables the charger………is it true that the battery voltage will then sink to 44.4v (3.7V/cell)?.....if so, then our end-of-charge comparator will be tripping on and off repeatedly.
Also, supposing the charging is done at zero degrees C…and the battery is charged up to 47V….then the temperature rises to 40 degrees c….what will the voltage of the battery then become?
Sorry I tried to answer this on batteryuniversity etc but couldnt find the info.
