Material selection and assembly method as well as component design are very important to determine the cost-effectiveness of battery modules and battery packs. Therefore, this work presents Decision Matrix, which can aid in the decision-making process of component materials and assembly methods for a battery module design and a battery pack design.
The industry standard thermistor is NTC 10K at 25°C and B=3950. Most battery packs are spot welded together using nickel strip for contacts. Soldering directly to the cells is dangerous for the cells. It is easy to melt or disturb the safety vent, thwack the seals, or cause internal shorting if the heat is too high.
Robust mechanical design and battery packaging can provide greater degree of protection against all of these. This chapter discusses design elements like thermal barrier and gas exhaust mechanism that can be integrated into battery packaging to mitigate the high safety risks associated with failure of an electric vehicle (EV) battery pack.
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 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.
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.
