Re: BMW's Percussion disconnect for Z3

What would be the result of an accident if the dent is in the area of the bettery and the terminal shorts to some other part of the body of the car. ?

I'm not sure the relay will help.

Insulation too

The cables in question will be exposed to temperature extremes (0-100 F in ambient swing alone).  The insulation of these cables will have to stand up to that, as well as engine heat, and do so for a design life of a decade or more.  No cracking or degradation of the insulation will be acceptable.

BMW's Percussion disconnect for Z3

The BMW 2000 Z3 already has the answer to post accident power removal  with percussion connector at positive battery post.

The unit is designed to fire and disconnect battery source upon deployment of airbag from accident.

Sehr gutes engineering von BMW!

Your imagination is correct, Rob. Even in non-accident situations, the use of higher voltages adds an additional layer of engineering, as Chuck points out, in the form of isolators. Supposedly, a high-voltage isolator fault was at issue in the recent Fisker Karma car which "died" when it was brought out to Consumer Reports's test track.

Greater potential shocks

I would imagine the high voltages would also come with higher potential safety problems. I would imagaine the higher voltages could be an issue in collisions.
