We all know that the series voltage of lithium batteries increases and the parallel capacity increases. So how to calculate how many series and how many batteries a lithium battery pack is composed of? Before performing the calculation, we need to know what specifications of batteries are used in the assembly of this lithium battery pack.
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.
Fill in the number of cells in series and parallel, the capacity of a single cell in mAh, and the voltage of a single cell in volts (default is 3.7V). Press the “Calculate” button to get the total voltage, capacity, and energy of the battery pack. This calculator assumes that all cells have identical capacity and voltage.
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.
The energy content of a string E bs [Wh] is equal with the product between the number of battery cells connected in series N cs [-] and the energy of a battery cell E bc [Wh]. The total number of strings of the battery pack N sb [-] is calculated by dividing the battery pack total energy E bp [Wh] to the energy content of a string E bs [Wh].
To get the voltage of batteries in series you have to sum the voltage of each cell in the serie. To get the current in output of several batteries in parallel you have to sum the current of each branch .
In order to increase the current capability the battery capacity, more strings have to be connected in parallel. For example, 3 strings connected in parallel will triple the capacity and current capability of the battery pack.
