Maybe this has been discussed somewhere but I haven't seen it. I was wondering if there might be some firefighters here that could answer this. When the Fire Department responds to a serious crash they occasionally have to cut and pry injured people out of the vehicles with saws, prying tools, and the Jaws of Life. In the process, they obviously "disassemble" the vehicle as quickly and efficiently as possible to get the victims the treatment they need ASAP. What happens if they happen to cut through electrical lines going from the battery to the motor(s) on these cars? I understand that the cars are using something like 375 volts so I'm pretty sure that cutting through these cables might not be a good thing for the firefighters and/or the people they're trying to rescue. Do firefighters receive training on where to cut into an electric car to avoid this type of hazard? Is there something like a master switch that they can turn off when they first get on scene to kill any juice coming from the battery? Has anyone ever heard of a firefighter getting injured or killed cutting into an electric car? Can the entire metal surface of the vehicle be electrified just due to the damage from a serious crash? Anyway, just something I happen to think about regarding some of the unconsidered (at least if you go by what I've NOT heard in the media) hazards of these electric vehicles.
