Hi, I am just beginning my EV project and I am very excited about it. I bought a cheap 82 Dodge Rampage with toasted engine, manual trans
, manual rack&pinion steering
, and, after a simple master cylinder change, manual brakes!
No extra drag on motor, or vacuum pump, etc!
I have been internet researching constantly and going back and forth about how to do it, either high efficiency which = high$$$ or inexpensively but not as fast and rangey. After finding an awesome deal on 8 new 155Ah 12v sweeper batteries with matched charging system (all from an electric Ranger vehicle?) and cables and trays and holddowns and a 48v-12v DC-DC unit, I think I have now settled on a simple 48 volt system. The car is light, just over 2200lbs curb weight, and the batteries add 693 back to it after I strip the ICE parts. Not sure what the motor and controller will add or what the ICE parts will subtract, but I doubt the weight will be much over original weight, maybe 2500 but I doubt it.
So now I am ready to buy a motor and controller and pot box. I keep thinking the 48v-72v D&D ES-15-6 would be good along with the Alltrax 7245 controller, because if I ever want to upgrade to 72 volts, I won't have to change either one.
Any thoughts on my choice? I don't have a big budget at all and they seem to be available and cost is very reasonable. Not knowing much about the different types of motors leaves me at a disadvantage, so I hope someone here will know something about whether the combo will work decently.
I am aiming for a 40-50 mile range. My one way work commute is just under 10 miles of 99% flat ground with 1 RR overpass and 1 freeway overpass to go over, only 3 or 4 lights once I get to town, so I was hoping to charge every 2 days. I was told I can charge it at work too!
Thanks in advance for any and all advice, info, criticism, etc...
