The ZENNCity electric car which would be the first vehicle to use these batteries has a 52kwh 250 mile range EESU that would only weigh 280 pounds.
EEStor is building a state of the art pilot production plant that is very significant. The Zenn Motors CEO and others have seen the EEStor plant.
EEStor is to deliver a production prototype off of the production line by the end of 2009. Once they deliver a production prototype it is a production unit that is production ready.
EEStor stores their energy at around 3500V. Zenn Motors would step that down to operating voltages likely in the 600 V range. Very very high efficiency drive system operating at much higher voltages than any other current EV drive system. That does a number of things. It increases the drive efficiency, it makes the components somewhat smaller, and ultimately less expensive and obviously for mass commercialization that's a very important consideration.
