EVS & Electric motors

EVS & Electric motors

The is no doubt that EV purchases are accelerating. Competition and innovation will improve the price, range, and recharge times. One comment I have heard is “It doesn’t make sense that EVs are more energy efficient. They require that the energy be created from another source, then stored in a battery then it propels the vehicle. With a gas engine, the source of power is already in the vehicle.” The answer is actually very simple. Electric motors are anywhere from 4 to 10 times more efficient. They have fewer moving parts (20 moving parts in an EV vs. 200 in internal combustion). This also allows the HP-to-weight ratio to be much, much better for EVs.

Had we listened to Tesla over a hundred years ago the Oil Barons would never have existed, we would have all been driving EVs long ago. However, two major issues still need resolving: The sources for recharging are primarily coal and natural gas (big polluters), and the environmental issues regarding lithium batteries.
