Theory of Battery Charging Condition

The Lithium ION Battery charging operation is a critical
phase because all cells are connected in series and a single
bad cell could effect the cycle time and the life of the bat-
tery pack.
Phase Recharging (With Maximum Current Available or under Light Charge)
• 1 - Cells Voltage Measurement
• 2 - Signal to activate the charger and regulate the delivery amount of current
• 3 - Line connected to the resistance
• 4 - Power Supply Line

At the start of battery charge, the BMS controls the char-
ger to provide the maximum current (as per setting) and
as soon as one cell reach the 3630 mV the BMS adjusts the
charger to reduce the current supply.
