What causes fire & explosion inside a Bess enclosure?

The leading cause of fire and explosion inside a BESS enclosures is the release and ignition of combustible vapors from an overheating battery.

What are the requirements for battery housings in E-vehicles?

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.

Are explosion-proof cells safe?

While the cells enclosed in an explosion-proof box are considered to be safe, there are reports that the thermal runaway propagation from a single cell will ignite the space within the enclosure to a pressure far beyond its limit [12, 18, 19].

What causes heat transfer outside a battery enclosure?

The heat transfer outside the enclosure is mainly caused by natural convection and heat radiation. The surface-to-surface radiation model was deployed in the simulation. The enclosure, encapsulation, and battery surface can be defined as gray-diffuse surfaces.

What are explosion-protection techniques?

Explosion-protection techniques (also called type of protection or explosion-protected apparatus) are classed under a generic term, which describes the use of particular techniques for constructing electrical apparatus for use in hazardous areas .

How thick is the battery housing?

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).
