The voltage of a battery pack is determined by the series configuration. Each 18650 cell typically has a nominal voltage of 3.7V. To calculate the total voltage of the battery pack, multiply the number of cells in series by the nominal voltage of one cell.
To calculate the capacity of a lithium-ion battery pack, follow these steps: Determine the Capacity of Individual Cells: Each 18650 cell has a specific capacity, usually between 2,500mAh (2.5Ah) and 3,500mAh (3.5Ah). Identify the Parallel Configuration: Count the number of cells connected in parallel.
The Open Circuit Voltage (OCV) is a fundamental parameter of the cell. The OCV of a battery cell is the potential difference between the positive and negative terminals when no current flows and the cell is at rest. The typical lithium battery OCV curves versus SoC then looks like: Some points to consider:
Charging Voltage: This is the voltage applied to charge the battery, typically 4.2V per cell for most lithium-ion batteries. The relationship between voltage and charge is at the heart of lithium-ion battery operation. As the battery discharges, its voltage gradually decreases.
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.
Battery capacity is measured in ampere-hours (Ah) and indicates how much charge a battery can hold. To calculate the capacity of a lithium-ion battery pack, follow these steps: Determine the Capacity of Individual Cells: Each 18650 cell has a specific capacity, usually between 2,500mAh (2.5Ah) and 3,500mAh (3.5Ah).
