What is battery discharge testing?

What is the charge/discharge behavior test for lithium-ion batteries?

The current industry standard QCT/743 for lithium-ion batteries for electric vehicles has been released for use In 2006, it is stated that the charge/discharge current for lithium-ion batteries is C/3, so the charge/discharge behavior test with C/3 is also often found in the charge/discharge test of lithium-ion batteries in the laboratory.

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.).

How do you test a lithium ion battery?

The best way to test a lithium-ion battery is with a multimeter. • A digital multimeter To test the battery, first set the multimeter to the “DC Voltage” setting. Then, touch the red lead of the multimeter to the positive terminal of the battery, and touch the black lead of the multimeter to the negative terminal of the battery.

What is a constant current discharge of a lithium ion battery?

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.

What happens when a lithium ion battery discharges?

When the lithium-ion battery discharges, its working voltage always changes constantly with the continuation of time. The working voltage of the battery is used as the ordinate, discharge time, or capacity, or state of charge (SOC), or discharge depth (DOD) as the abscissa, and the curve drawn is called the discharge curve.
