Requirements for matching battery cabinets

Employers must consider exposure to these hazards when developing safe work practices and selecting personal protective equipment (PPE). That is where Article 320, Safety Requirements Related to Batteries and Battery Rooms comes in.

Requirements for battery housings in e-vehicles are extensive: regulatory requirements; functional requirements; consideration of the installation conditions, transformation of forces and torques into the vehicle structure as well as wishes and demands of the end customer for trouble-free operation under a wide variety of climatic conditions.

It is a requirement to have all the documentation in place prior to authorized personnel entering a battery room to perform a specific work task on a battery system under normal operating conditions. However, it is likely the employee will need to enter the battery room to deal with a battery system that is not operating normally.

The battery housing (B: HOUSE®) has an approx. 15 mm thick GVI® insulation - open on one side. The insulating effect is sufficient to keep the battery pack at operating temperature for more than 12 hours without additional heating! (ambient temperature minus 20 °C; starting temperature of the battery 25 °C; temperature after 12 h 20 °C).

Battery backup cabinets placed outside the outer physical envelope of a building or structure (e.g., cabinets mounted on roofs, or on the outside of buildings). Battery backup cabinets located in open parking garages and open stadiums where the cabinets can be exposed to outside weather conditions and pollution levels.

Depending on the required thermal properties, the total wall thickness is between 5 mm and 15 mm. One possible design variant of a fully enclosed battery is shown in Figure 7. With the concept of a multifunctional battery housing - B: HOUSE® - a wide variety of basic requirements can be fulfilled within one single unit.
