I am a geologist from Latvia (Eastern Europe)
and newbie to EVs and this forum!
Unfortunately in my country EV is still something out of science fiction... But I have been quite close to green technologies for several years and finally decided to give it a try!
I am new to EVs, but read quite a bit of info on internet and also e-books. I also have some mechanical experience with drilling rig & truck repairs. I already made some calculations @ http://www.evconvert.com/tools/evcalc/
and Seth's Leithman's book.
So planned things:
Ford Ka 1999
Range recommended up to 60 miles
Speed up to 60-70 mph
Planned budget for now is about 8000$
Curb weight before conversion ~1800 lbs, w/o ICE parts I expect 1300 lbs hopefully
. After conversion curb weight expected ~ 2500 lbs (yeah, because of lead-acids...)
Power required 15,6kW @ 60 Mph, 22kW @ 70 Mph on flat ground, calculated from aero drag + rolling resistance (there are no hills here)
Now I'am considering DC 144V system, but also interested AC (because of efficiency & regen). I know, forum is full with AC vs DC things, but for me $$$ could be an issue.
So what do you think about such setup:
ADC FB1-4001A, 9.1" 144V DC motor
Curtis 1231C controller
12 x Trojan T-1275 12V 150 Ah = 18kW batteries at beginning. If I could gather more $, then LiFePO4 ~45 x 3,2V x 160Ah = ~23 kW.
Or better try to aim @ high voltage & lower amps & AC system?
Would Trojans bring really these 18kW to motor? I am watching that lead acids are quite critisised @ forum!
Maybe there is someone from Eastern Europe to show his vehicle and share some experience? Also parts getting could be a problem. I was shocked when I found that Impulse9 costs around 4000$ @ Sweden!!!
