The lithium-ion battery discharge test mode mainly includes constant current discharge, constant resistance discharge, constant power discharge, etc.
The discharge curve basically reflects the state of the electrode, which is the superposition of the state changes of the positive and negative electrodes. The voltage curve of lithium-ion batteries throughout the discharge process can be divided into three stages
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.
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 charging conditions of the battery: charging rate, temperature, cut-off voltage affect the capacity of the battery, thus determining the discharge capacity. Method of determination of battery capacity: Different industries have different test standards according to the working conditions.
