Ars Technica: “How does the US Environmental Protection Agency decide how far an electric vehicle can go on a single charge? The simple explanation is that an EV is driven until the battery runs flat, providing the number that goes on the window sticker. In practice, it’s a lot more complicated than that, with varying test cycles, real-world simulations, and more variables than a book of Mad Libs, all in an effort to give you a number that you can count on to be consistent and comparable with other vehicles on the road.”
