electricity is “100% available” energyAlthough much more than an ICE, electric motors are not 100 percent efficient. Chargers are not 100 percent efficient. Batteries do not take up the charge, nor discharge at 100 percent efficiency. Nor is the entire drivetrain 100 percent efficient.
All true, in the real world. In an ideal, lab bench, world, I make no doubt that conversion of electrical energy to mechanical work could (e.g., using superconductors in the motor) be done with awfully close to 100% efficiency. And I did use scare quotes around the expression “100%” available.But I must quibble about “drive train” efficiency - in that no transmission is required for the EV. One less (mechanically complex) part of the drive train . . .
Tesla's still have a gear box, albeit a single-speed fixed one. With AWD, there are two.
