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.
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.
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.
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
Pre-charging is when the battery is initially plugged in and is drawing a very small amount of current in order to get the chemical reaction started within the battery. Constant current charging is when the majority of the charge is applied to the battery.
