Charging Optimization Methods for Lithium-Ion Batteries

Battery terminal voltage and charging current can be easily measured in real time. The polarization voltage is small at a very low current. The values of charging/discharging polarization voltage are approximately equal to each other, but the signs are opposite in the steady state. Ohmic resistance voltages are same. Therefore, the OCV curve can be obtained

6 FAQs about [Lithium battery charging current and voltage curve]

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.

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.

Are battery charging voltage curves equal?

Due to the ohm voltage and the polarization voltage, the battery voltage curves cannot be completely equal. However, comparing the charging voltage curves at different current rates, it can be found that there is a strong similarity in the shape of the battery charging voltage curve.

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.

What is a lithium battery discharge curve?

The lithium battery discharge curve is a curve in which the capacity of a lithium battery changes with the change of the discharge current at different discharge rates. Specifically, its discharge curve shows a gradually declining characteristic when a lithium battery is operated at a lower discharge rate (such as C/2, C/3, C/5, C/10, etc.).

What is charging voltage curve analysis?

At present, charging voltage curve analysis methods are widely used in studies of battery characteristics and the constant current charging voltage curves can be used to analyze battery aging mechanisms and estimate a battery’s state of health (SOH) via methods such as incremental capacity (IC) analysis.
