At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease. Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current.
Because the battery is charging continuously for a long period of time, even a slight fluctuation in the charging voltage results in a big difference in the expected service life of the battery. It is essential to ensure accurate control to minimize charging voltage fluctuations.
Going below this voltage can damage the battery. Charging Stages: Lithium-ion battery charging involves four stages: trickle charging (low-voltage pre-charging), constant current charging, constant voltage charging, and charging termination. Charging Current: This parameter represents the current delivered to the battery during charging.
The problem with this method is that the charging current flows in a large quantity at the final stage and causes over charge. Care should be taken to avoid charging for more than the specified charge period. (2) Constant current charging method This method consists of charging the battery with constant current.
So as charging continues at a constant voltage, the charging current decreases due to the decreasing potential difference between the charger-output voltage and the battery terminal voltage as the battery charges. Expressed differently, the charging current is highest at the beginning of the charge cycle and lowest at the end of the charge cycle.
There is clearly some current flowing into the battery while in the constant voltage (CV) charging stage, meaning electrons must be flowing. Wouldn't that mean the amount of free electrons trapped in the graphite layer would increase and thus the voltage would (slightly) have to increase?
