Surfing through the YouTube, I ran across a big Harley electric conversion that included a sidecar with a bio-diesel generator for charging on the road/extending range.
This got me thinking and looking for a generator, and it turns out good old Honda (and others) have 1000 and 2000 watt generators that weigh 29 and 46lbs respectively. Mounted on a rear-carrier, I was thinking Hybrid! I did not see anything diesel/biodesiel of similar dimension, let me know if you do!
But is it worth it - ie, what sort of mileage would this hybrid have given all the conversions between mechanical and electrical and back?
First off, the 1000 watt version should be enough for my chargers. The Soneil 1212SRs actually only push 12 volts at 5 amps max = 60 watts. Times 5 of these is 300 watts.
The Honda EU1000i's tech specs indicate it can run full tilt for 3.8 hours, using 0.6 gallons of fuel, or 1/4 load (250 Watts) for 8.3 hours. This represents 3800 Watt-Hr or 2075 Watt-Hrs respectively.
How many miles per Watt-Hr is Tronbike getting? Looking at the full history, 190 miles have consumed some 23.5 KW-Hr according to the Kill-a-Watt. Division gets us 8 miles/KW-Hr, which was a bit of a relevation.
What is the max range? 3.3KW-Hr pack times 8 miles is 26.4 range.
MPG from the Honda EU1000i under perfect conditions? (ie assuming all charge captured in
a timely enough fashion, Soneil claims their 5 amps to be as fast as 10 amp equivalent chargers, thats still
55amp-hr/10 amp = 5.5 hours.)
Best case: 3.8 KW-Hr times 8 miles/KW-Hr = 30.4 miles divided by 0.6 gallons = 50.7 MPG.
Worser case: 2.075 KW-Hr times 8 miles/KW-Hr = 16.6 miles divided by 0.6 gallons = 27.6 MPG
Using this particular generator for high MPG is not a good use of fuel. Adding the range might be interesting, but a better pack of a Lithium type battery is a cleaner, more progressive approach to the range problem.
New battery manufacturer was found today, KOKAM, used to power the www.proev.com racecar.
