How to protect your battery energy storage system from fire?

Battery energy storage systems (BESS) need solutions for protecting the battery from fire and the surroundings from a fire in the battery room. Thermal runaway could for example occur if the battery is exposed to high temperature and in its turn lead to a fire. Roxtec seals are certified to prevent fire, flames, smoke, and heat from spreading.

What is a sealed battery box?

The design of the sealed box focuses on the flow of battery cooling airflow, and any leakage must be avoided to ensure consistent performance. To achieve this, the upper cover and the lower bottom of the battery box must be free from any perforations or gaps, and a gasket should be added between them during assembly.

Why is EVs battery pack sealing important?

The sealing of the EVS battery pack is very critical to the battery pack’s safety in the box. New sealing structures and sealing materials are constantly emerging. Battery pack sealing is constantly being explored, evolved, and improved.

Why are large-scale gaskets used for battery maintenance?

This causes battery maintenance problems because in order to seal the housing again, a new lid with sprayed-on gasket is required. This is the reason why large-scale gaskets are used when tough technical require-ments need to be met. Seal function redundancy is achieved through profile design.

Why do you need a battery seal?

Battery systems are crucial for continuous operation when ordinary power supply is not available. Reliability and performance are therefore key throughout the lifecycle of the systems. Roxtec seals provide excellent cable protection and cable retention to prevent damage and faults.

How to seal a battery?

The seal should firmly ad-here to the lid and have a good compres-sion set. Various technologies are avail-able to achieve this. Among them: me-chanically foamed polyurethanes or two component silicones, such as elastomers or foams. If the battery is only rarely opened or not at all, adhesive are possible solutions.
