Here’s a little trivia you can impress your gas-guzzling friends with. The first all-electric vehicle (AEV or EV) was built in 1839. By 1900, 38% of all cars in America were all-electric. And then Henry Ford revolutionized the way cars were built, and oil was cheap, and the internal combustion engine became the default power source for the automobile.
But that may be about to change.
At the heart of it, all cars are essentially energy conversion devices. They both convert stored energy (gas in a tank or electricity in a battery) into kinetic mechanical energy (moving) to propel the vehicle. How that energy is converted and how that kinetic energy makes the wheels go round are the principal differences between a “conventional” auto and an electric vehicle.
Probably the easiest way to explain how an electric vehicle works is to compare it to a conventional vehicle, so let’s start by looking at the components.
