Lithium-ion batteries are rechargeable battery types used in a variety of appliances. As the name defines, these batteries use lithium-ions as primary charge carriers with a nominal voltage of 3.7V per cell.
The nominal voltage of lithium-ion cells is typically around 3.6V to 3.7V. This is the average voltage when the battery is in a stable state, neither charging nor discharging. State of Charge (SOC) is crucial for monitoring battery health. For best performance, lithium batteries should be within specific voltage ranges:
Cut-off Voltage: This is the minimum voltage allowed during discharge, usually around 2.5V to 3.0V per cell. Going below this can damage the battery. Charging Voltage: This is the voltage applied to charge the battery, typically 4.2V per cell for most lithium-ion batteries.
Here is 12V, 24V, and 48V battery voltage chart: Generally, battery voltage charts represent the relationship between two crucial factors — a battery's SoC (state of charge) and the voltage at which the battery runs. The below table illustrates the 12V lithium-ion battery voltage chart (also known as 12 volt battery voltage chart).
It is recommended to maintain the battery within the voltage range of 3.0V to 4.2V per cell to ensure optimal performance and avoid permanent damage to the cells. Lithium battery voltage is essential for understanding how these batteries operate.
A typical lithium-ion battery voltage curve is the relationship between voltage and state of charge.
