Talk me through an EV! I'm tempted to build, but no real knowledge!


I have a hairbrained idea that building an EV version of a car could be a fun way to get a cheap commuter- that and a decent way to use some of the scrap and guff over at my unit.

I currently have a 64 mile commute each day- taking upto 1.5hrs each way, with no option to charge at work (although I could ask nicely!)

Charging would likely be at home overnight off my domestic supply

As I understand it, I need the following

1. Vehicle to be converted (likely RWD for ease of connecting to gearbox/bigger motor/skidz!)

2. Electric Motor

3. Potentiometer

4. Batteries

5. Controller

6. Charging system

7. Regen braking setup

So I need you folks to advise me on the following points

Electric Motor

What size do I need? 70 mile range at 50+mph

I understand that its amps drawn that's the key to matching output/heat/range?


What type?

How many Volts?

How to connect and balance?
