      From: muratlanne@gmail.com              "Bob La Londe" wrote in message news:vq01gg$denj$1@dont-email.me...              My real insight though was, "What if we could use industrial motor       inverters instead of auto industry proprietary distribution inverters?"       --------------------------------              Would the regenerative braking when you decelerate be acceptable?              I've worked as electrical tech on some EV projects as well as the Segway.       The wiring for the prototype electric motorcycle for [mumble] was very       simple, battery to controller, controller to motor and throttle to       controller.              Writing this is competing with Bob Dylan at Newport on PBS, and he's       winning. OK, pledge break.              I needed expensive special tools to crimp the connectors. Since then I've       collected them at flea markets. Testing required recording voltages, motor       current and temperature. I mounted an industrial datalogger on the       motorcycle "tank", a laptop with connected DVMs would work in a car or       truck.              A sometimes overlooked problem with Lithiums is that the battery suddenly       stops drawing charge current when full, and the charger voltage may spike       up, especially with a solar controller. I burned out an inverter that way,       and am now experimenting with voltage-limited charging to somewhat less than       100%.              Bye, I aint gonna work on Maggie's farm no more.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
