The charge and discharge current of a battery is measured in C-rate. Most portable batteries are rated at 1C. The c rate of lithium ion battery is a critical parameter that determines its power output, capacity, and lifespan.
Constant current discharge is the discharge of the same discharge current, but the battery voltage continues to drop, so the power continues to drop. Figure 5 is the voltage and current curve of the constant current discharge of lithium-ion batteries.
The capacity of a lithium battery refers to the amount of charge the battery can store. It is usually expressed in milliamp-hours (mAh) or ampere-hours (Ah). By integrating the lithium battery charge curve and discharge curve, the actual capacity of the lithium battery can be calculated.
One important characteristic of lithium battery discharge rate, which refers to how quickly the battery releases its stored energy. Understanding the lithium battery discharge rate is crucial for determining the battery’s performance and suitability for different applications. What Is C-rate?
It is usually expressed in milliamp-hours (mAh) or ampere-hours (Ah). By integrating the lithium battery charge curve and discharge curve, the actual capacity of the lithium battery can be calculated. At the same time, multiple charge and discharge cycle tests can also be performed to observe the attenuation of capacity.
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 C-rate? How to Read Battery Discharge Curves
What Is C-rate? The C-rate is a measure of the charge or discharge current of a battery relative to its capacity indicates how quickly a battery can be charged or discharged. Definition: A C-rate of 1C means that the battery will be fully charged or discharged. in one hour.. For example, a 2000mAh battery at 1C would be charged or discharged at 2000mA (2A).
