eBike is now solar charged tooSummer 2011 Version 2.0Lighter, Faster, Safer +GPS-WiFi-3G. . . . . & even more Solar Power !Visit www.thekpv.com THEKPV began in 2008 by me Terry Hope. I had worked as an engineer aboard Copper Sky. An 88ft steel haul sailboat. The captain would not allow a full size electric scooter.. I had only one option.. design a vehicle that will fit inside a suitcase.As seen on:Treehugger.com http://www.treehugger.com/file... http://green.autoblog.com/2010... http://ireport.cnn.com/docs/DO... http://inhabitat.com/2010/11/0... specs.44 lbs396 Wh Battery13 km Range15 min recharge 80%28 Wh 12v booster10,000 cycles10.8V Capacitor50 lbs w/Solar Array50 Watts solar power12V Kinetic gen device Super capacitor 310F (farad) charge and discharge5 Ultra capacitor's from Maxwell Technologies BOOSTCAP 2.7 volts 310 farads eachre-charging from harvested kinetic energy on my electric ebikeDemonstration values : Capacitor voltage : 8.0 V / battery pack voltage : 30V (9xM1) Motor & battery pack amp draw with no load : 3amps with generator load : 4.5a - 4.6aSuper Capacitor voltage increases 0.5V in 15 seconds.At approx. 1 min I flip a toggle switch that arranges the caps into series with the 30 volt battery pack increasing power to 38 volts. The extra power works like the push-to-pass button used in formula 1 racing called KERS.The ebike generator shown here has 6 individual dynamo's.The alternator output is NOT tuned for efficiency in this video, and does come at a price of introducing more drag to the rear wheel rotational speed. Tuning the output on a free spinning wheel to the least drag in the range of 0.2-0.3 amps. And would probably increase when tuned with the bike and rider weight.What to call this prototype vehicle ?bicycle with no pedals ...mini superbike ?pocket ebikesolarcycle ?electro solar e-bike ?hybrid bicycle ?hybrid scooter ? ...
