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.
When it comes to connecting the cells in your battery pack, you have two options: welding or soldering. Welding is the preferred method as it provides a stronger and more reliable connection. To weld the cells together, you will need a spot welder and pure nickel strip.
Once you have selected the right cells for your battery pack, you need to plan the layout. Cells can be connected in series or parallel to increase capacity or voltage. Connecting cells in series increases the voltage of your battery pack, while connecting cells in parallel increases the capacity.
The battery pack capacity C bp [Ah] is calculated as the product between the number of strings N sb [-] and the capacity of the battery cell C bc [Ah]. The total number of cells of the battery pack N cb [-] is calculated as the product between the number of strings N sb [-] and the number of cells in a string N cs [-].
A battery pack is made up of several components, including battery cells, protection circuitry, and a battery management system (BMS). The battery cells are the building blocks of the battery pack, and they are typically connected in series or parallel to achieve the desired voltage and capacity.
The battery pack will be designed for an average energy consumption of 161.7451 Wh/km. All high voltage battery packs are made up from battery cells arranged in strings and modules. A battery cell can be regarded as the smallest division of the voltage. Individual battery cells may be grouped in parallel and / or series as modules.

The number of battery cells connected in series N cs [-] in a string is calculated by dividing the nominal battery pack voltage U bp [V] to the voltage of each battery cell U bc [V]. The number of strings must be an integer. Therefore, the result of the calculation is rounded to the higher integer.
