Disassembly of energy storage square battery cell

What makes disassembling battery housings easier?

All battery housings are assembled using screws which is beneficial for the disassembly since it is possible to remove the lid without damaging it. However, a large amount of screws is needed, making it a time-consuming activity and an increased number of parts results in longer lead times as well as higher material usage.

Why is a battery disassembled?

A battery is disassembled for several reasons, such as service or recycling, to access and move different parts safely since high voltage is involved. During these actions, it is significant for the battery to be safe to work with.

Can a battery be removed from a thermal system?

The surrounding sub-assemblies can then also be removed without interfering with any part of the thermal system, leading to easy service and disassembly of the battery.

How is a battery design developed?

The development of a battery design involves assessing design solutions from an assembly, disassembly, and modularity point of view. Based on this evaluation, an “ideal” battery is created with a focus on hardware components such as the housing, attachment of modules and wires, thermal system, and battery management box.

How are battery housings assembled?

All battery housings are assembled using screws. This method is beneficial for disassembly as it allows for the removal of the lid without damaging it. However, it requires a large amount of screws, making the assembly process time-consuming, and results in longer lead times and higher material usage due to the increased number of parts.

What are some ways to modularise a battery?

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