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.
(Recommended) Charge Current – The ideal current at which the battery is initially charged (to roughly 70 percent SOC) under constant charging scheme before transitioning into constant voltage charging. (Maximum) Internal Resistance – The resistance within the battery, generally different for charging and discharging.
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.
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.
It involves charging at a low current, typically about 10 percent of the set charging current. Battery Characteristic Curve: This curve depicts the relationship between voltage and capacity during charging. It helps visualize how voltage changes as the battery charges.
Understanding The Battery Charging Modes: Constant Current and Constant Voltage Modes Charging is the process of replenishing the battery energy in a controlled manner. To charge a battery, a DC power source with a voltage higher than the battery, along with a current regulation mechanism, is required.
