Day 29

The EV1 may seem to be a technological marvel, but in fact it really wasn’t. The design was largely based on the same design created in 1979 in a project funded by the Department of Energy and produced by Chrysler, GE and NASA’s Jet Propulsion Libratory (JPL). The project was called ETV1 (Which stood for Electric Test Vehicle, sound familiar, ETV1, EV1). It was an all electric two seater sports car with a T shaped battery compartment that went between the passengers, just like the EV1. Don’t believe me? Take a look at it. http://home.earthlink.net/~vincewirth/etv1.jpg and http://home.earthlink.net/~vincewirth/etv1bat.jpg . The first EV1s were not much more sophisticated than the ETV1 However, the advances to batteries, electric drive systems, controllers and more that have been developed since the introduction of EV1. These innovations have been largely spurred on by the California CARB board’s original Zero Emission Vehicle (ZEV) mandate. Those technologies have not disappeared even though the ZEV mandate has been weakened. Many of the companies and organizations developing those advancements have kept on innovating. In fact that may be the entire reason GM was so active in killing the EV1. Electric technology advanced so rapidly in that time period that it could very well have overtaken the internal combustion engine. From the sound of the gun of the CARB boards ruling came a flood of new technologies. The Department of Energy put its money behind Stanford Ovshinsky’s invention, the NiMH battery. http://www.time.com/time/reports/environment/heroes/heroesgallery/0,2967,ovshinsky,00.html. Alan Cocconi, one of the main designers of the Impact, (GM’s prototype for the EV1), has gone on to produce the tzero electric super sports car. http://www.acpropulsion.com/tzero_pages/tzero_home.htm Electrovaya produces the most energy dense battery in existence, the paper thin lithium polymer battery. http://www.electrovaya.com/innovation/zev_tech.html New Generation Motors, the company that produces most of the motors for the World Solar Challenge vehicles is making motors for an electric vehicle for India and has motors on the drawing board for many types of vehicles. http://www.ngmcorp.com/ WaveCrest, Valance, Glacier Bay, the list goes on and on. Let’s face it, EV1s are great, but the technology that could be available today would make an EV1 type car a much much more desirable and practical vehicle. Back to the ETV1, there was an ETV2. A parallel hybrid mechanically almost identical to the 1st Prius only with bulky lead acid batteries requiring it to have two sets of rear wheels to support the weight. NiMH made the Prius practical.
