Understanding Lithium Ion Battery Current Variation During Charging
Battery capacity and state of charge have a direct impact on the current variation of a lithium-ion battery. As the battery reaches higher states of charge during charging, the current gradually decreases. Similarly, during discharging, as the battery''s state of charge decreases, the current also decreases.

How does the voltage and current change during charging a lithium-ion battery?
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.
What is a lithium battery charging curve?
The lithium battery charging curve illustrates how the battery’s voltage and current change during the charging process. Typically, it consists of several distinct phases: Constant Current (CC) Phase: In this initial phase, the charger applies a constant current to the battery until it reaches a predetermined voltage threshold.
How to charge a lithium ion battery?
When the cells are assembled as a battery pack for an application, they must be charged using a constant current and constant voltage (CC-CV) method. Hence, a CC-CV charger is highly recommended for Lithium-ion batteries. The CC-CV method starts with constant charging while the battery pack’s voltage rises.
When does a lithium ion battery charge end?
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
What happens when a lithium ion battery is charged?
Steady Voltage and Declining Current: As the battery charges, it reaches a point where its voltage levels off at approximately 4.2V (for many lithium-ion batteries). At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease.
How does a lithium battery charging curve affect the charging speed?
During the charging process of a lithium battery, the voltage gradually increases, and the current gradually decreases. The slope of the lithium battery charging curve reflects the fast charging speed. , the greater the slope, the faster the charging speed.
