Interesting article about "high" voltage automotive systems, Michael. I feel some concern about possibly being electrocuted by my car, though! For one thing, we are frequently exposed to their metal parts while also standing in the mud. These systems had better have extreme reliability with regards to electrical insulation and freedom from loose broken wires.

ECD's battery would meet those needs better than any other existing technology. (This happens to be my own personal opinion based upon what I know about this subject.) Does anyone else know of a better battery than NiMH? Now, wouldn't that be a nice twist for a change? " As for KNOWING about a better automotive battery, I doubt that anyone truly knows. However, LiPoly batteries are definitely being looked at seriously for SLI (starting, lights, ignition) applications - and for EV and HEV use as well. The Delphi division of GM (now spun off) had a working relationship with VLNC until recently. Delphi's interest was stated to be for SLI use. Opinions vary as to why this relationship was allowed to lapse. Some say Delphi was satisfied it now had acquired the basic technology to produce a SLI LiPoly battery - some say Delphi was giving up this hope. I have no convictions either way. My opinion is that Delphi and others seek a much cheaper battery than NiMH appears to promise. At least present NiMH costs are not encouraging. I wish GM would use some of its vast funds to greatly increase automotive NIMH battery production capacity, and take the risk of lowering the price in advance of sales - before other technologies receive such support. Just today, the SI VLNC board has been discussing a rumor that VLNC batteries will be used for space applications (due, I believe, to having the highest energy capacity of in- production, safe, rechargeable batteries). Again, I have no conviction about this rumor, but I believe in keeping close tabs on the competition - and LiPoly batteries ARE serious competition.
