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.
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.
In the first cycle, in order to meet the requirements of rapid battery charging, it has a large charging current in the early stage and the corresponding temperature rise will increase. At a certain stage, the temperature decreases because of the health loss limitation, so the charging current also decreases.
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. This point is commonly referred to as the “charging cut-off current.” II. Key Parameters in Lithium-ion Battery Charging
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.
1. Constant Current (CC) Stage During the initial phase of the charging cycle, the battery is charged at a constant current. The voltage gradually increases while the current remains constant until it reaches a predetermined threshold. This stage ensures that the battery charges quickly and efficiently. 2. Saturation Stage
