The more energy you put in a box, the more explosive it is. EV fires are already a problem so fire depmts are going to have to evolve, and quickly
That’s technically true but also true for a very wasteful combustion reaction with all the energy gasoline has in it. It’s not quite that simple, as the potential energy for, say, lithium oxidation is much higher than you’d get from charging and discharging a battery.
The energy stored is only part of the equation.
I am not saying this as a dig on EVs, ICE vehicles can go die in a hole for all I care, its just a reality that more energy is more energy and you can’t escape it.
I understand that. My point was that the lithium oxidation from combustion vastly outstrips the power charged. You could create a hell of a fire with an uncharged lithium battery. The underlying reactivity of materials do not have a direct link to the battery’s storage.
I would disagree. There is a direct connection between the state of charge and how violent the failure is for the lithium battery in cases where it is punctured, cut, or folded. (Not uncommon in car crashes)

BEV battery fires are also staggeringly less common than ICE vehicle fires.

People seem to think that my comment was pro-ICE, and it is not.

Maybe not intentionally but it still serves as fearmongering.
