I got into an interesting conversation with some friends this weekend. I know electric motors are quite different from gas powered engines, but wouldn't an electric motor benefit from having a transmission? For example, a gas engine that revs at 2,000 RPMs is more efficient than the engine revving at 5,000 RPMs. The range of our cars increases as we drive slower, which means the motors are running at a lower RPM (right terminology?) and drawing less power. So if you had a two speed transmission, once you hit a cruise speed of 70 MPH, it would switch to the second gear which is optimized to have the motor rev (again, right terminology?) at a lower rate but keep the speed at 70. Thoughts? Sorry in advance if this is a dumb question..I'm not an engineer or anything close to being that! Thanks for the feedback!
