As a battery pack designer it is important to understand the cell in detail so that you can interface with it optimally. It is interesting to look at the Function of the Cell Can or Enclosure and to think about the relationship between the Mechanical, Electrical and Thermal design.
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.
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.
It is composed of 16 modules with 432 cells of the type 18650 and a NCA chemistry, resulting in a total of 6912 cells in each pack. (42) Furthermore, the cells inside the modules are packed in groups which are wired in series to each other, creating a battery inside the battery. The same goes for the modules which also are connected in series.
Concentration is on the hardware of a battery pack. Access information due high degree of confidentiality. The placement of the batteries on the vehicle is given and is not investigated. The project started at the 21st of January 2019 and is aimed to be completed at the 14th of June 2019, as presented in the GANTT-chart in Appendix A.1.
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.
