    Trukr, you asked wich setup i was going with for the motors, we have decided on the porsche setup.
    Stacked motors are puuurty.

    Here's a guy in the EU that does twin and triple AC conversions on exotics.

      trukr, where do I find the EV album? Regarding my EV setup, I don't have any specific design other than an AC motor & lithium batteries. I'm just absorbing ideas.

      EV Photo Album: Our Electric Cars on the Web

      On the diy site look for posts by mizlplix. He's ran both direct and auto.


      No I haven't read anything about that study. A really high C rating would be nice, but we would still need a way to pull that much power that fast without lighting up the wiring at home. Sounds good for commercial charging stations though.

        Well it looks like a change of plans for me. I've been given an opportunity to set up shop back home and throw my hat in the ring replacing the jeepney with an EV alternative. Current alternative is an unappealing extended chinese golf cart.

        I plan on adding that mad mechanics touch to the jeepney, trike, fx, taxis and owner types. The 2 seater is going to have to be thrown on to the backburner.

          I dont want to star a war here and this is just my personal view on it and dot get me wrong. The concept of EV type cars are great and I would have liked mine to be EV, but there is a major flaw with the idea and that is batteries. Unlike your regular combustion engine, EV car preaty much has to be plugged in every night. As grocery getters and run about to the mall etc. they are perfect.

          Problems I see with them as true electric
          limited distance
          time to recharge, mind you some can be carged on couple of hours but need the provided power for it.
          typical setup is heavier then convensional combustion engine
          limited places where you can plug the car in to have it recharge

          what I like is
          acceleration is quick provided you have enough batteries

          what would be nice is a hybrid ie small gas engine that runs electric generator to extend range and recharge if parked that does not have a plug for charging

            No worries, that's exactly what this thread is for. It's the back and forth that will either identify real issues that need to be dealt with, or add some clarity to popular misconceptions.

            It's true that the EV version of a car can be heavier, but you have to remember that ~90% of the total vehicle weight will be below the upper lip of your rim. That is, if the chassis is done properly with the pack below floor level. A CG that low makes for really nice handling.

            You"re also spot on with the initial expense of lithium batteries... it really is a hard pill to swallow. For an EV to make any sense to non-treehuggers, the car would HAVE to be a daily driver. If you size the pack properly for it's actual daily use then the more miles you drive, the more money you save. There is no hope to recoup the cost of the pack and begin to save money if the car is a garage queen or sunday night cruiser.

            What I've discovered with this jeepney project I'm working on is that, if I finance a set of floodies to a driver for a year and factor in the cost of charge, he would be able to add another 25% to his daily income. That's while he's paying off the pack. After the pack is paid off, he adds 75% to his daily income. If he takes care of the pack, he should be able to go 2 plus years before needing replacement. That's a substantial increase in income for anyone. If he's smart and saves some of that money to go lithium, than those savings increase dramatically; not to mention the performance and range. All that is just the savings from his diesel costs at current rates. It doesn't even take into account the money he saves in maintenance and repairs.

            You can't compare the pack to an empty gas tank, it's not the same thing. You have to compare the price of the pack to the amount you would've spent on fuel for the life of your particular pack, minus the cost of charge.

            The green aspect is a byproduct to me. (Much like the 80% of wasted energy into heat and noise is for engines.) It's merely a novelty to most. It's the economics that will eventually convert people. Like I explained on the tesla thread, I spend $7800 on my commute yearly in gas. If I had gone electric earlier, I would only be spending ~$800 a year in electricity for charging. $7000/year is a lot of money over the expected 10 year life span of a properly maintained lithium pack. I would not be willing to give up that kind of savings for those few times a year I would need to go on an extended trip. That's what the dodge ram will be for.

              I really like the EV idea from an environmental viewpoint but when you factor in what it takes to generate the electricity to charge the car I am not sure they are as "green" as some would like to think. I drive a Geo that gets me 50+ MPG and I often drive over 100 miles in a day running around the Dallas area chasing parts and such. I have looked into what it would cost to build an EV that would work for me and by the time I figure the initial cost and the running costs it just won't work out for my situation. I think the ideal would be something that had a small, very efficient diesel engine powering a generator that would extend the range by charging the battery when I am stopped somewhere but not necessarily have enough charging power to directly drive the electric motor. Until someone invents better, more affordable batteries the EV will be at a decided disadvantage to the IC powered vehicle.
