Importantly, the DC power source ensures that it does not exceed the maximum battery voltage limit during this adjustment. The relationship between the charging voltage and the battery charging current limit can be expressed by the formula: Charging voltage = OCV + (R I x Battery charging current limit) Here, R I is considered as 0.2 Ohm.
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.
Charging Voltage: When you recharge a battery, the charging voltage is the amount of voltage applied to push current back into the battery. This voltage is typically higher than the nominal voltage to ensure the battery reaches a full charge.
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.
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.
Load Voltage: This is the voltage a battery delivers when it is powering a device or under load. It tends to be lower than the OCV because the battery’s internal resistance causes some energy loss. Charging Voltage: When you recharge a battery, the charging voltage is the amount of voltage applied to push current back into the battery.
