"Fireman Access" is a port emergency crews can access to flood the battery compartment and extinguish an EV fire in minutes

Seems like pretty good idea. The graphic makes look like it could be hard to access though.

It's not intended for manual access. The goal would be to sit back, douse the car with a firehouse, and leave enough of an open path so that the water pressure alone breaks the seal and floods the battery. This is what firefighters are already doing, so this design simply makes the default action more effective. I'm a big fan!

> When attacking the vehicle fire, understanding that once the contents of the fire are extinguished, sustained suppression on the battery pack may be necessary. Use a large volume of water such as multiple 1 3/4-inch hand-lines to suppress and cool the fire and the battery. Put water on the burning surfaces.

Yeah, is it on the bottom? Seems like there should be a pipe somewhere more accessible or something.

Wherever it is, firefighters need to be informed of it so that they can make a decision to do the right thing quickly when they are under pressure. I think about various signs like these

that exist to help firefighters quickly understand what they are up against.
