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.
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
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.
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.
In consideration of battery charge polarization and temperature rise constraints, the optimized charging strategy can be summarized as follows. First, taking the acceptable charge current as the optimal charge current limit, the battery is charged with high current at the initial charging stage to speed up the charging process.
Overall, it takes 3426 s (57.1 min), which is theoretically the fastest charging time without lithium deposition, to fully charge the battery. This result is successful as it is able to support the optimal charge current theory presented previously, providing a general principle for fast charging of lithium ion battery.
