Handling of Li-ion battery fires

Safe & efficient handling of Li-ion battery fires

In collaboration with several other companies and organisations, Cold Cut Systems has investigated whether Cobra can be used on lithium-ion battery fires. After years of systematic testing and knowledge acquisition, Cold Cut Systems is delighted to finally be able to pass on our knowledge and experience to others. The test results have been very positive, showing that stopping lithium-ion fire propagation with Cobra is possible.

Fully developed propagations in lithium-ion batteries are very rare. But when they occur, Fire and Rescue Services lack a practical method to interrupt the process of fire and thermal runaway in batteries using lithium-ion technology.

Until today, the methods available mainly comprise different ways of limiting fire spread and/or cooling the propagating battery pack externally with large amounts of water. In addition, there is a risk of re-ignition when handling affected lithium-ion batteries.

Based on the findings, we can present a manageable solution to one of the Fire and Rescue Services biggest challenges. The test results show that there is a method for extinguishing fires in lithium-ion batteries.

Tested & Proven

We received early indications that Cobra could be a suitable tool for this type of fire. However, one of the cornerstones of Cold Cut Systems’ philosophy is that what we say about Cobra and its effects must be properly tested and evaluated. We, therefore, started a pre-study in 2021 to investigate Cobra’s effect when used on lithium-ion fires.

The results from the pre-study showed promising results for further studies and tests. In 2022 we therefore, joined a collaborative project.

This new project is a joint effort between automotive industry stakeholders and equipment manufacturers, with the Swedish Civil Contingencies Agency (MSB) as project leader.
