This news about ultracapacitors is huge. Never mind the details, the notion of using capacitors instead of batteries is very attractive: capacitors don't care how fast you charge them or discharge them, they don't use up any energy themselves, but simply store it. They don't g...

The Ovonics NiMH batteries solved two problems that had plagued electric cars for decades: 1. Short range (low energy/weight ratio) 2. Short battery life (2-3 years life on lead-acid was not uncommon) The Ovonics NiMH had a energy/weight ratio that was about double of the lead...

Most people would not know or think about the following. I have to admit the slick response the S-10 was not built as a ground up EV does at first sound reasonable. However this answer from GM Dave Barthmuss is vague and for good reason. They do not want you to consider the fo...

I will second that the S10 EV was also completely unknown to me until I stumbled across one on ebay (being sold by evbones...a rarity to see them on ebay). I helped to build and race Montana State University's solarcar entry in to GM's 1995's SunRayce. In 1995 the energy was h...

I have the opposite opinion, although no hard data. A slow charge using 120V would not heat up the batteries so the heat pump would not go on if the ambient temperatures are moderate (like much of the year in Oakland). This would be more efficient charging (albeit longer) beca...

So, should we conclude from this that the 120V charger is useless on the NiMH S-10s? This confirms Jeff's opinion when I asked him about the old EV1 120V 1.2kWchargers. He said that these are useless because no or very little amps will reach the pack when the heat pump is runn...
