These numbers include regeneration (converting vehicle kinetic energy back to electricity to charge the battery). I don't drive on the freeway much, and generally hold it down to 65MPH. Most of the time, I'm using city streets at 45.<br /><br />Kurt: It looks like you've added a J1772 connector for charging - does this support charging at 240V using public chargers? I'm also interested in your motor/controller - using a DC motor with PWM? Regeneration?Brett.cgbhttps://www.blogger.com/profile/01438060389500505671noreply@blogger.comtag:blogger.com,1999:blog-6520221750573392688.post-10224990520062521072012-11-16T12:03:30.452-06:002012-11-16T12:03:30.452-06:00You have to remember that all the major companies ...You have to remember that all the major companies that make electric vehicles, Tesla, Nissan, Citroen, etc. test them at unreasonably low speeds in optimal conditions. Even the new Tesla S model ranges are reported at 55 mph instead of 65 mph, which makes a great deal of difference because air resistance goes up in the third power of speed.<br /><br />Any figures you see in the media, especially for cars that haven't yet gone through EPA testing, add 50% and you get close to what they really do. 300 Wh/mi is still extremely optimistic.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6520221750573392688.post-53979525301026515942012-11-05T15:59:13.377-06:002012-11-05T15:59:13.377-06:00On my RX-7 conversion I was hoping to see 250wh/mi...On my RX-7 conversion I was hoping to see 250wh/mile but the best I have seen is 311 and the worst was about 350. However I am still driving it like a teenager. But I have lots of stuff to work on still. Your car looks great!
