Since I'm in the market for a Zero Motorcycle I have been reading their site's every page. When I read their 10 years of history I was taken back by their very first offering since its power train was the same that I fabricated in 2005. Celebrating 10 Years of Innovation || ZERO MOTORCYCLES I...

Tesla Motors How Elon Musk and Company Made Electric Cars Cool, and Sparked the Next Tech Revolution By Charles Morris I dl a copy from Amazon last night, finished it this morning. Having been a tinkerer in EVs for the last 15 years, the book was to a small degree a trip down Memory Lane for...

After returning to this forum after a 4 year absence, I have been trying to catch up this last week. This forum has quite a collection of knowledgeable EV folks, so is a good place to bounce some ideas. I saw Alan Cocconi's Tzero at the '97 LA Auto Show and was truly impressed with both the...

I've always wondered why the original Alan Cocconi inverter speed controller used on the Tzero that had vehicle to grid interface wasn't used in the Roadster and future offerings. This AC Propulsion controller that was developed for California's Zero Emissions Mandate was rated at 150 kW, more...

First let me say this forum seems to have quite a collection of informed folks and has been a real pleasure posting here. I come from many years of hot rodding and to be quite frank, the hot rod forums are a den of,,, well lets just say not the most progressive group of folks. Every time I even...

I know it is charging DC but how does it get enough power from a typical pole transformer that is shared with other energy users? A 6 bay charger station filled with cars needing a charge, even derated 50% and 100% efficient (which it isn't) would be pulling 360 kW from a distribution...

About 15 years ago I decided I wanted to design a little electric scooter that would have the potential to beat a Harley to 40 mph. I can tell you first hand those HD riders are not amused by a electric scooter taking them out. Etec motor with a peak hp of 25.7, 48 volt, 400 amp controller...
