Many consider a Tesla Electric Vehicle (EV) a computer on wheels. Software changes are transmitted to your vehicle to add new features, install fixes and capture performance data. I will discuss the technologies used in the Tesla: the AC induction motor, the Lithium-ion battery and the Tesla Gigafactory that produces Lithium-ion battery packs. Also, we will look at the hardware and software that enable autopilot and full self-driving: surround cameras, ultrasonic sensors, radar and artificial intelligence. In the fall of 2017, an affordable mass–produced EV, the Tesla Model 3, will roll off the assembly line, and by then we should know a lot more about this vehicle.
