In the battery pack, to safely and effectively manage hundreds of single battery cells, the cells are not randomly placed in the power battery shell but orderly according to modules and packages. The smallest unit is the battery cell. A group of cells can form a module. Several modules can be combined into a package.
Part 4. Voltage and capacity Voltage and capacity are fundamental characteristics of any battery pack. In Li-ion batteries, the voltage per cell usually ranges from 3.6V to 3.7V. By connecting cells in series, you can increase the overall voltage of the battery pack to meet specific needs.
Lithium-ion battery packs consist of rechargeable batteries using lithium ions as the primary component. They offer high energy density and efficiency. According to the U.S. Department of Energy, lithium-ion batteries have a specific energy of 150-250 Wh/kg. This makes them suitable for smartphones, laptops, and electric vehicles.

[PDF Version]An automotive lithium-ion battery pack is a device comprising electrochemical cells interconnected in series or parallel that provide energy to the electric vehicle. The battery pack embraces different systems of interrelated subsystems necessary to meet technical and life requirements according to the applications (Warner, 2015).
Conclusions Usually, for the implementation of lithium-ion cells in different applications, they experience expansion during charging and discharging cycles. Pressure loads are applied to battery cells in automotive battery packs to avoid contact loss among battery pack ingredients and misshaping during operation.
To achieve this, 260 cells of the 21700 model of lithium-ion cells are used in series-parallel combinations, following the current standard specifications. The performance of the designed battery pack is evaluated for the urban dynamometer drive schedule (UDDS) drive cycle current profile as the load.
To meet the increased power capacity and voltage requirements for electric vehicle (EV) applications, hundreds of lithium-ion cells are combined in series and parallel to form a battery pack, as individual cell capacity and voltage levels are insufficient to drive the motor load (Feng et al., 2022; Gandoman et al., 2022).
Accurate determination of the continuous and instantaneous load capability is important for safety, durability, and energy deployment of lithium-ion batteries. It is also a crucial challenge for the battery-management-system to determine the load capability of a pack due to inevitable differences among in-pack cells.
However, previous research acknowledges that different vibration tests proposed in standards and regulations for lithium-ion battery packs vary substantially in the levels of energy and frequency range (Kjell and Lang, 2014) so there is still a big challenge to emulate a test that represents the real working condition of electric vehicles.
CalculationsTotal Pack Voltage (V) = Number of Cells in Series * Single Cell VoltageTotal Pack Capacity (mAh) = Number of Cells in Parallel * Single Cell CapacityTotal Pack Energy (Wh) = (Total Pack Voltage * Total Pack Capacity) / 1000.
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.
Variation in cell capacity and resistance along with number of cells in series and parallel will determine the actual energy capacity of any pack. Temperature management of the cells and variations across the pack will influence power and energy.
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.
Resistance of the cells, connections, busbars and HV distribution system will determine the power and energy capability of the pack. Variation in cell capacity and resistance along with number of cells in series and parallel will determine the actual energy capacity of any pack.
The operating voltage of the pack is fundamentally determined by the cell chemistry and the number of cells joined in series. If there is a requirement to deliver a minimum battery pack capacity (eg Electric Vehicle) then you need to understand the variability in cell capacity and how that impacts pack configuration.
This 18650 battery pack calculator is used to determine the optimal configuration of 18650 lithium-ion cells for a specific power requirement. With a 12V battery pack with 10Ah capacity, the calculator would determine how many 18650 cells to connect in series for voltage and in parallel for capacity.
