Something all EV cars need is a trailer with an auxiliary battery as an an option. It could add 50 to 75% to the range. Then the auxiliary battery could conceivably be charged at the same time as the car’s battery. This effectively almost doubles the charging rate.

It’s very expensive. Would anyone buy them. Some might buy 2, maybe 3. Maybe not. Maybe it at least rates some marketing research.

One thing I do know is that I am limited to about 80 mile trips as it is. Maybe 150, 160 with such a trailer. One way trips, I’m talking almost 400 miles.

As an side thought, the batteries could be built and added in modules so it wouldn’t hit the old pocket book all at once.
