The longer the duration of the platform area, the higher the platform voltage, the slower the voltage drop. 3) When the battery power is nearly finished, the battery load voltage begins to drop sharply until the discharge stop voltage is reached.
The voltage of the battery is the potential difference between the positive electrode and the negative electrode. The specific key parameters include open circuit voltage, working voltage, charge and discharge cut-off voltage, etc.
The most important key parameter you should know in lithium-ion batteries is the nominal voltage. The standard operating voltage of the lithium-ion battery system is called the nominal voltage. For lithium-ion batteries, the nominal voltage is approximately 3.7-volt per cell which is the average voltage during the discharge cycle.
The more stable and longer time the better of the level, because the Battery is to use that period of voltage stability. Such as: nominal 3.7V Lithium Battery platform voltage is about 3.7V, the nominal 3.2V iron Lithium Battery platform voltage is about 3.2V.
This phenomenon shows that the battery in the platform period is very stable, with short relaxation time and small voltage drop after charging. Table II. The time constant of a stage in charge. Repeat the above calculation process and calculate the time constant of each charging stage during the charging process.
The SoC voltage chart for lithium batteries shows the voltage values with respect to SoC percentage. A Li-ion cell when fully charged at 100%SoC can have nearly 4.2V. As it starts to discharge itself, the voltage decreases, and the voltage remains to be 3.7V when the battery is at half charge, ie, 50%SoC.

At the beginning of charging, the battery is charged with a constant current of 0.5 A. When the battery voltage rises to the platform period, the battery is charged with a current of 1 A. When the battery is charged to 80% SOC, the battery is charged with a current of 0.5 A again until the battery is full and overcharged.
