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's new in battery design?

Batteries in general is also revised to get a better overview of what functions and parts are included in a battery in order to map its functions in an Enhanced Function-Means model. This model creates an image of how the functions and design solutions are connected to each other.

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 happens if a battery module moves around?

If the modules would move around, the energy supply to the vehicle is disabled and the modules could potentially collide and get damaged. Moreover, by using the “click on, click off” solution for high voltage batteries might contribute to faster wear out on the connections and a decreased isolation.

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 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.
