6 Frequently Asked Questions about “Battery charging current and discharging current”
What happens when a battery reaches full charge?
When the battery reaches its full charge cut-off voltage, constant voltage mode takes over, and there is a drop in the charging current. The charging current keeps coming down until it reaches below 0.05C. The battery reaches full charge voltage some time after the CV mode starts (as soon as one of the cells reaches its full charge voltage).
What is the difference between charging and discharging a battery?
Charging and Discharging Definition: Charging is the process of restoring a battery's energy by reversing the discharge reactions, while discharging is the release of stored energy through chemical reactions. Oxidation Reaction: Oxidation happens at the anode, where the material loses electrons.
How does a battery charge IC work?
CV (Constant Voltage Charging) The constant voltage (CV) threshold for lithium batteries is typically 4.1v to 4.5v per cell. The charging IC monitors the battery voltage during constant current charging. Once the battery reaches the constant voltage charging threshold, the charger IC transitions from constant-current to constant-voltage regulation.

Charge Voltage – The voltage that the battery is charged to when charged to full capacity. Charging schemes generally consist of a constant current charging until the battery voltage reaching the charge voltage, then constant voltage charging, allowing the charge current to taper until it is very small.
What is a constant current charging stage?
During the constant current charging stage, the battery can safely output a higher charging current between 0.5C and 3C. Constant current charging continues until the battery voltage reaches a “full” or float voltage level, and then enters the constant voltage charging stage. Stage 4. CV (Constant Voltage Charging)
