Lithium-ion batteries are available in different voltage sizes, the most common being 12 volts, 24 volts, and 48 volts. Each API has a different voltage rating for a specific discharge capacity. It is also helpful to know the voltage and discharge rate of a lithium battery.
Keeping the battery charged within the recommended voltage range helps to optimize battery life and ensure consistent performance. For instance, driving an electric car on a low battery voltage range may cause the battery to run down quickly, leading to expensive replacements.
In a battery pack, if there is a difference in the voltage of a single cell, then during the charging and discharging process, certain cells may reach their upper or lower voltage limits earlier, resulting in the whole battery pack not being able to fully utilize its capacity, thus reducing the overall energy efficiency.
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. One can calculate the battery is to be discharged based on the voltage when the SoC is 0%. The voltage of a cell, in this case, is 3.0V.
