I would appreciate if all of you would tell me it cannot be done. It
will help my level of determination:)
I have a 1994 Ford Aerostar 4wd. 3500 lbs curb weight. It may not be
the best candidate so I may sell it and buy a different van.
Requirement # 1 : Absolute limit of $20,000.00 to convert existing van
or 20k plus sales price of current van. $13,000 w/o sale is my target.
Requirement #1.1: This van has a pay load of 2000 lbs and the towing
capacity of 4500 lbs which means the brakes will not be lacking when I
add batteries. If I replace it I would like the other van to be comparable.
Requirement #2: With a front axle using cv joints and a posi rear
differential I can do a series hybrid with 3 dc motors or parallel with
one AC permanent magnet motor and achieve the low current/high voltage
necessary for long range/hill climbing that will get me to my camp sites
at the coast pulling a 1000 thousand lb trailer. Okay now here is where
I really need you guys. I have not yet used a spreadsheet to calculate
the energy required to get 5000 lbs up a 2 Km 15% grade or short 20%
grade. Also, if valence accumulators are used this will require a lot
of boost from a genset or pusher and/or capacitor stack. Cost may turn
out to be prohibitive.
Requirement #3: Pure electric drive around town will give me the cargo
space to be soccer-dad/grocery shopper for a family of 5. This vehicle
will also pull a trailer of 1000 lbs of garbage or home improvement
supplies for rental houses.
Thanx for any help in planning this people. I know I am pushing the
envelope. If anyone with a lot of experience wants to talk in Salem then
lunch is on me. Or we can have a long telephone conversation. I
really think this is doable.
