It is also noticed that, the efficiency of the battery sharply increases when the charging current surpasses the discharge current, it is explained using Peukert’s law which states that, “As the rate of discharge of the battery increases, the battery's available capacity decreases”.
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.
It consisted of charging the battery at different constant current rates, storing in it, 5 A-hours, in terms of battery capacity, during each of the charging processes, then discharging it while measuring the Capacity Restituted (CR). The charging was performed using a DC supply.
The charging current decreases as the internal battery voltage increases. ●When the charge current reaches the set termination value, charging is continued for a fixed interval then stopped. Example of ROHM’s Charging IC Profile (with Charging Cord Plugged In)
Here is a general overview of how the voltage and current change during the charging process of lithium-ion batteries: Voltage Rise and Current Decrease: When you start charging a lithium-ion battery, the voltage initially rises slowly, and the charging current gradually decreases. This initial phase is characterized by a gentle voltage increase.
As the State of Charge (SOC) increases, the battery charging current limit decreases in steps. Additionally, we observe that the battery voltage increases linearly with SOC. Here, Open Circuit Voltage (OCV) = V Terminal when no load is connected to the battery. Battery Maximum Voltage Limit = OCV at the 100% SOC (full charge) = 400 V.
