How a battery design is developed?

The design solutions are assessed from an assembly, disassembly and modularity point of view to establish what solutions are of interest. Based on the evaluation, an “ideal” battery is developed with focus on the hardware, hence the housing, attachment of modules and wires, thermal system and battery management box.

What happens after a battery module is assembled?

After the battery module is assembled, it needs to be placed into the battery tray. As this tray is a key structural component of the vehicle as well as integral in protecting the battery cells, it needs to be of the highest strength and stability.

What are Cs and DS in a battery pack?

Cs on the battery pack relates to the given space on the vehicle, the volume, and the weight since the battery adds to the total weight of the vehicle. The DSs that interact with each other are the Outer- and Inner Casing with Hardware since they affect one another when a design change is made.

How many modules are in a car battery pack?

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.

How do you design a battery pack?

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.

How a battery can be modularised?

A battery has several ways to implement modularisation and among these are design of the housing and module as well as concerning the management of its environment.
