If you found this video helpful. Please help me by sending some interesting information about something that you in your country or in your brigade are good at, that we can learn from in Sweden. Send it to po@utkiken.net.

Thank you PerOla for making an English version. I'm based in Australia, BEVs are just arriving in our market now and your videos will help us better manage fire situations.

A lot of same findings as we have had with testing to learn how to act in case of battery fire. We had also the idea of using water, but we were afraid of further short circuiting the cells. Any experience with this topic, or would this be just not realistic? Thinking was, if you mix water with contaminants coming from Cells, the water would start to conduct, and cause whole pack to short circuit constantly. This is likely something we will further investigate later on, especially seeing the effectivity on this video. For Fire blanket we found, that the heat would be contained, and caused the battery to burn even faster. We are quite worried about the gases released during the fire and if one inhales them, and that is something we are planning to investigate in near future. Very good and educative video about battery fires, will share with our Rescue groups!

Thanks for your comments. Could you please share your findings with me? Both the fire blanket tests you made and when you learn more in the future. Sounds like interesting lessons. po@utkiken.net is my email address.

I just read your comment again and realize I did not anwer it completely. Yes I have experience with using water into the battery packs and I have not seen any indication that the water would further short circuit the cells. Of course there might be currents travelling from plus to minus due to the contaminated water, but I have seen no problems due to this.

Do you have any suggestions for lithium ion battery packs onboard ships

If it is in battery rooms on electrical ships I think a fixed system that both contains the propagation of the thermal runaway to one module, prevents explosion by inerting the atmosphere and makes it possible to vent it without sending in personnel would be a good thing. But I have not looked at that question in detail so my answer is not based on a thourough analysis of the problem.

@@UtkikenRescue - I think that unerring may not work as the oxides contain their own oxygen, so will continue burning. Was thinking fixed installation plus some form of injection system direct into the battery cells

@@PaulCoatesTrailRunning You are right about inerting not working as a way to stop the propagation of the thermal runaway. I have seeen several studies on it that supports that. My thought of inerting was as an explosion prevention if you get a thermal event with venting of combustible gases.
