ok, so.. just to summarize the related info. For Emergency Responder safety and comfort in rescue should you ever need it, I would recommend:

- designs to include routing HV under middle of car to avoid possible cuts w/ jaws of life, main pack fuse, circuit breaker, key-switch contactor, and:

- inertia switch in the key-switch 12v+ to your main contactor which will cut power in case of crash

- some obvious badge or sticker on driver's side at very least identifying vehicle as electric (presuming they understand that means having high-voltage)

- manual pull 'kill' switch/lever/pull reachable from outside driver's window that a Responder might be able to see and pull to feel 'safe' before going in w/ jaws of life....

I have my own vinyl cutter and made some 3" high voltage (triangle with lightning bolt inside) and put one on the back and high on both front fenders. My car also has "electric" stickers on it. I plan on integrating an inertia switch soon too.

My ultimate plan would be to get the DMV license plate division to issue a new plate for electric vehicles. That way we could use our local parking charging stations (gas cars get ticketed if they park there) and let people know the vehicle is electric.


Here is a link for the U.S. NATIONAL ELECTRIC VEHICLE SAFETY STANDARDS SUMMIT report. Don't know if anyone has looked through it but it has quite a lot of information for the safety standards for mew EV's.

I hastily scanned the U.S. NATIONAL ELECTRIC VEHICLE SAFETY STANDARDS SUMMIT report. It appears to be a report on the meeting. I didn't find any definite recommendations. It did mention NEC 625 which covers charging electric vehicles. It appears that charging at over 120 volts or 20 amps could have some insurance implications.

I am putting a decal on the bottom left corner of the windscreen (near the VIN#) that says "In emergency pull yellow connector by hand brake". There is the large anderson connector right obviously there. I also encased the + and - in separate 1" pvc from trunk to front batteries. One time one of the electric order pickers stuck on forward for no reason (contactors welded shut) with no stopping it. Running past customers until the driver had the savy to run it into the wall, VERY scary as you think about it.

not exactly a safety issue, but caught my eye. you may be better off to run the + and - together inside a larger pipe. The closer together they are, the more they cancel each others EMF, and would have more air space around them for cooling for continuous high current draw.... but that is a minor concern.

You also should try to run down the center of the car, perhaps in the old exhaust tunnel, and avoid runs along the edges so as not to be subject to damage in accident or cut with 'jaws of life' if they need to pry open doors.

There is also a heavy duty switch we use in our drag cars to disconnect power in an accident or fire. That switch is usualy located on the outside of the car at the rear as a turn switch or a push pull on off. These switches are off heavy equipment rated at high volts and I believe 2000 amps. Most emergency responders are familiar with these switches here in the US. Only problem is there always turns out to be a funny guy who likes to pull or turn a switch located on the outside of a vehicle just for fun to see what happens, so probably not a good idea to put it outside & clearly marked but a thought.

My project is a two door hatchback. I'm thinking of putting a label on the two fixed windows behind the doors and on the hatchback glass. I'm reluctant to use the word "Danger", but I do want to put a diagram on it. That way, First Responders would feel comfortable using whatever means necessary to get anyone out. Here's the label I'm thinking of:

My goal was to show the cable routing as well as the location and count of batteries. I also wanted to highlight that they're not exotic LifePo or Flooded Lead Acid batteries.

I didn't want to get into locations of fuses, disconnects, or the impact sensor. I just wanted to provide reassurance that it's okay to chew up the doors or pillars as necessary.

Comments Welcome,
Phillip

thats nice! AND provides info for the casual parking lot neighbor that will see it

I think I would trim the text down. I wouldn't want someone reading a novel as I bleed out in the car.
