Hi everyone
I have been reading and looking up different projects on here for a little while trying to determine if building an EV is right for me.
I have a Hillman Imp that I bought some time ago,its basically a basket case but that is not a problem.deciding if going EV or a 2 Cyl Deisel is.
The Imp is a small 4 seater british car,rear wheel drive with a rear mounted motor and gearbox,similar to an old VW bug.
So I was thinking if I replaced the dead motor with an electric ,it could make a neat and interesting EV that we could use to run around the area with and at the same time would satisfy my eldest daughter who has the desire to save the planet!
now we get to the stuff I have no idea about.
How big and how many batteries (voltage ect)
The car is about 1600Lbs complete and will carry 4 adults,I will probably convert it into only 2 adults.The original motor had about 50 HP,I dont think I need it to be that strong,but I dont want to look like a fool either and it should be able to move along at say 30 mph or so.
I will keep the transmission,no clutch,not worried about the controller yet at this point (probably use the open source controller,as I like that concept).
I figure by limiting the car to 2 people that should allow me to use an extra 300 ils of batteries where the people used to be.
I would also mount some of the batteries in the front where the gas tank used to be (this car was always nose high,this should bring it down a little)
I am not worried about suspension,brakes,or anything with the body,I have done a bunch of cars in the past,so this part is easy for me.Brakes and suspension upgrade are quite easy to find for the Imp so that is not a concern either.
How do you determine how much battry power to shoot for when building an EV.
as close as I can figure ,After stripping out the ICE parts and limiting the car to 2 people,I will have availible about 300lbs (the electric motor will weight quite a bit more than the ICE motor it replaces) without performing any uograde or increaing the normal weight if the car.
I am assuming I can go a bit higher and contain at least 400 to 450 lbs of batteries between the front center and rear of the car without too much problems.
So basically I am looking for 30-35 MPH,with a range of say 30 miles (can be less in both cases) If all goes well the entire car would weight less than 2000Lbs,all in.
what sort of motor would I need,and what sort of power would be required.
Thanks a bunch guys
