The battery pack has a rectangular shape where its length can be modified, depending on the capacity needed. The battery housing will be modularised in a way that three lengths of plate exists, to create a larger space for packs needing additional modules.
The battery pack will also have a main voltage sensor, for monitoring the voltage of the entire stack and a series of temperature sensors, such as thermistors, located at key measurement points inside the pack. Collection of data from the pack sensors and activation of the pack relays are accomplished by the pack’s battery management system (BMS).
The BMS and power relays can be found inside the pack whereas the DC-DC converter, HV controller and other HV units are mounted in other parts of the vehicle. Furthermore, the pack consist of ten modules, divided in two rows and two levels with the lower modules containing 30 cells and the upper modules 24.
When designing a battery pack, it is important to weigh different parameters against each other to acheive a suitable design. It is therefore significant for these tradeoffs to have a valid foundation to stand on. One tradeoff that needs to be accounted for is comparing safety of the battery against its weight.
The packs’ primary components are the modules, often connected electrically in series and constructed by a set of cells. These cells can either be cylindrical, prismatic or pouch as illustrated in Figure 6. (4) The electrolyte used in the battery packs varies depending on what kind of cell that is employed.
Choosing the right cooling mechanism for a lithium-ion battery pack for electric vehicles and developing an appropriate cooling control plan to maintain the heat contained within a safe range of 15 to 40 degrees Celsius is critical to boosting safety, extending the pack durability, and lowering cost.

To become more environmental friendly, Volvo wants to exchange the combustion engines with electrical engines and replace the liquid fuel with batteries. Adding a part to a vehicle means it must be assembled as well as disassembled which results in a need for a product that is optimal for an assembly-line.
Protection: To protect the battery pack and the connected devices, it is important to include appropriate protection mechanisms. This may include overcurrent protection, overvoltage protection, and temperature monitoring. These safeguards are essential to prevent damage to the battery pack and ensure safe operation.
