EV Battery Assembly: Fire Protection (Step 8)

2 minute(s) to read October 24, 2022

It is only a matter of minutes. If the battery cells of an electric vehicle (EV) get inflamed, passengers should only need a few minutes to leave the vehicle. The answer is to secure the battery from burning through its cover by applying a fire protective material. Fire protection is all about saving lives. Getting the process right offers additional health advantages and material savings.

Right steps from the beginning

Applying fire-resistant materials to the battery cover is a complicated and challenging process. The material needs to be applied very precisely and seamlessly. Any gaps will jeopardize the fire protection ability, but applying too much can later cause assembly issues due to tight design requirements. Throughout the EV battery assembly process, it pays to get each step right from the beginning but in no instance is this more valid than for fire protection.

When applying the fire-resistant material, it is essential for safety reasons to ensure a certain thickness of the material layer across the entire surface of the battery cover. Different solutions are used for applying the material, such as airless spray or a wide flat stream.

No exposure to hazardous epoxy particles in the air

We recommend using an SCA flat stream applicator when applying the fire-resistant material. In contrast to a spray applicator, workers are not exposed to hazardous Epoxy particles. In addition, the 2C (two-component) material can be applied, allowing for optimal fire protection capabilities within physical design tolerances without wasting valuable material.

Quality assurance is key, and it all starts with an integrated vision solution. Automated sensors scan the battery cover after applying the fire-resistant material to detect any inconsistencies in the application quality.
