Customer ServiceHere 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.
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.
I. The Charging Characteristics of Lithium-ion Batteries Charging a lithium-ion battery involves precise control of both the charging voltage and charging current. Unlike other types of batteries, such as cadmium nickel and nickel-metal hydride, lithium-ion batteries have unique charging characteristics.
As the charging rate increases, the faster the active material reacts, the faster the battery voltage increases, and the energy loss generated increases. Therefore, the actual charging capacity of the Li-ion battery with high current charging is lower than the charging capacity when charging with low current.
Charging a lithium-ion battery involves precise control of both the charging voltage and charging current. Lithium-ion batteries have unique charging characteristics, unlike other types of batteries, such as cadmium nickel and nickel-metal hydride.
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
