Grade: A
This label for an electric car uses a "mile per gallon equivalent" measure so that consumers can, more-or-less, compare the mileage they might get to that of an electric car.
It also provides information like the time it takes to fully charge the battery and, most importantly, driving range on a full charge.
The information is clearly and simply presented and, assuming the calculations are done in a reasonable way, should help consumers understand what they're getting when they buy an electric car.
