Let me start off by saying, everyone gave good technical advice. I think fooljoe has the right approach. Sometimes people can become overwhelmed by technical knowledge and jargon. An early adopter/enthusiast usually will dig in to absorb as much as they can about EV's.
We are starting to enter a time where these cars are starting to appeal to mainstream buyers. These buyers are less likely to care or think about the tech. They are mostly interested in just using the car.
Sure they have to learn the basics of how to fuel and where to find charge stations, but mostly want it to look good while being cheaply and easily transported where they want to go.
We don't want to overwhelm these buyers/potential buyers. We may have to be a little easier on them and simplify as much as possible. They are not going to care why it works, just that it does work and fits their needs.
To round out my thoughts, I'm just glad that they are not dumping gas down a hole!
