So how do you build an EV? That was the first question we had to ask. And the answer is: the opposite of a normal car. The first preconception we had to remove from our thought process was that a larger motor means higher speeds. It doesn't. Unlike a gasoline engine, electric motors depend almost completely on the batteries running them.
While a larger motor can in fact handle more power, more often than not, the batteries are the determining factor for any EV. But the problem with batteries is the ammount of space they consume. Before we could even consider batteries, we would have to find out how much space we would have left after the motor was installed. The only way to do that of course is to buy a motor. So after several weeks of planning we decided to buy a Netgain Warp9 9 inch electric motor, and a Zilla Z1K HV controller capable of handling 1000 amps of current at over 300 volts (thats over 300,000 watts or 402.3 horsepower!) Turns out though, that the motor was back ordered 4 months and the controller was back ordered 6 months. Now we would just have to wait.
