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.

How can automated disassembly be introduced in the future?

Once the production of batteries has increased, automated disassembly can be introduced in the future. For this to be possible, it is important to consider the design of the battery and to make sure it has a minimized amount of materials and parts, in addition to suitable joining techniques.

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.

How are internal and external batteries benchmarked?

Thereafter, benchmarking of internal and external batteries is performed by using the functions as guidelines, resulting in a variety of design solutions. The design solutions are assessed from an assembly, disassembly and modularity point of view to establish what solutions are of interest.

What are some examples of module assembly & disassembly?

Another good example of module assembly and disassembly is found in Tesla S which also has modules mounted to the pack with four screws. To access these screws a plastic cover must be removed, but once that is gone, it is easy to unscrew the modules and later on lift them.

Can a battery management box be used in a heavier truck?

Two respectively three of these frames, modules, can be applied in the heavier trucks. The battery management box is its own module for the reason that it is separated from the battery modules and the same box content can be used regardless which truck.
