7GEN: How $100 Oil Could Help

How $100 Oil Could Help "As speculative fervor continues to test the $100 mark, fears that expensive oil could spur inflation and cripple consumer spending is spreading. Pricey oil—coupled with the subprime crash, shaky credit markets, Wall Street turbulence, tensions with Iran and a feeble dollar—could be the catalyst that topples the U.S. economy into recession." Okay... and I do hear a lot of people complaining about high gasoline prices.

The Battery Pack


The Battery Pack

After much investigation I have come to the conclusion that lithium rechargeable battery's are the battery of choice. They are the best value for money in terms of power to weight ratio. I have to keep the bike somewhere in the original weight range to get it registered, and i also want the bike to have as great a range as possible with the latest technology available. I am looking a making a battery pack consisting of 40 3.2V 40A lithium battery's that weight about 1.5kg each. So that gives me a total battery pack with a nominal voltage of 128V at 40A and a weight of 60kg. This works out to be a ~5kw battery pack. So it should run the 3kw motor for at least 1.5 hours.I am going to make 40 fake batteries of the same dimensions that i am looking at using to make sure i can physically fit them in the bike. I have the leftover room where the electric motor is and petrol motor was, i also have some room up front near the headlight that I may be able to squeeze a few in and also where the air-cleaner was and of course under the seat where the petrol tank used to be. I also have to be careful to leave enough room for the battery charger and motor inverter.
