At the same time, the end voltage change of the battery is collected to detect the discharge characteristics of the 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.
Keep the discharge power unchanged, because the voltage of the battery continues to drop during the discharge process, so the current in the constant power discharge continues to rise. Due to the constant power discharge, the time coordinate axis is easily converted into the energy (the product of power and time) coordinate axis.
During the battery discharging period, the Li-Ion battery voltage discharges from 4.2 V at fully charged state to 3.0 V at the end of discharge voltage (EDV). The battery voltage reaches the EDV earlier under higher discharge current than under lower discharge current due to the battery internal impedance effect.
The battery voltage reaches the EDV earlier under higher discharge current than under lower discharge current due to the battery internal impedance effect. This means that the useable battery capacity is smaller at the higher discharge rate than at the lower discharge rate.
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.
Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
