When selecting a lithium-ion battery pack, understanding its voltage characteristics is crucial for ensuring optimal performance and longevity. Three key voltage terms define a battery's operation: Nominal Voltage, Charged Voltage, and Cut-Off 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 average nominal voltage also means a balance between energy capacity and performance. Additionally, the voltage of lithium-ion battery systems may differ slightly due to variations in the specific chemistry.
Lithium-ion batteries function within a certain range at which their voltage operates optimally and safely. The highest range where the fully charged voltage of a lithium-ion battery is approximately 4.2V per cell. The lowest range which is the minimum safe voltage for lithium-ion batteries is approximately 3.0V per cell.
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.
Minimum voltage is the absolute lowest voltage a battery cell can reach before severe degradation or damage occurs. While batteries should generally not be discharged this low, it serves as a hard limit for extreme conditions. For a 3S Li-ion battery pack, the absolute minimum voltage would be 7.5V (2.5V × 3). Why Is Minimum Voltage Important?
It prevents over-discharging and overcharging, both of which can degrade battery performance and pose safety risks. For a 3.6V lithium-ion battery, the typical cutoff voltage is: 3.0V for discharge. 4.2V to 4.35V for full charge. Maintaining these voltage ratings ensures the longevity and reliability of the battery.
