Technical FAQs 4

What is constant current – constant voltage charging (CC-CV)?

Constant Current – Constant Voltage Charging (CC-CV) is where a battery cell is charged at a constant current until it reaches the maximum charging voltage at which point the voltage is fixed and the current reduced. The following graph shows this relationship versus charge time.

What does CC-CV stand for in battery charging?

It guarantees no Li-plating as E NE is constantly above 0V vs. Li/Li +. Constant Current – Constant Voltage Charging (CC-CV) is where a battery cell is charged at a constant current until it reaches the maximum charging voltage at which point the voltage is fixed and the current reduced.

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.

What is the charge curve of a lithium ion cell?

This charge curve of a Lithium-ion cell plots various parameters such as voltage, charging time, charging current and charged capacity. 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.
