SCIENCE VERSUS YOUR LITHIUM-ION AND EV FIREFIGHTING FEEDBACK

EV Channels Review

This video delves into the critical issue of EV battery fires, specifically examining a novel firefighting technique deployed by Danish Vikings using a super-cooled, high-concentration brine solution. The reviewer, John Cadogan, praises the ingenuity of the system, highlighting its effectiveness in absorbing heat and discharging batteries to prevent re-ignition. He discusses the potential for this method to be adapted for broader applications, including onboard ferries and as a secondary hazard control measure on land. Cadogan also addresses concerns about chlorine gas production, citing scientific studies that suggest the quantities are negligible compared to other toxic off-gassing from thermal runaway events. While acknowledging the logistical challenges of transporting large volumes of brine, he strongly advocates for the development and deployment of such systems, emphasizing the increasing frequency of EV battery fires and the inadequacy of current countermeasures. The review concludes that while not perfect, the brine solution represents a significant step forward in managing a serious societal risk.
