It is indeed a challenge. However, there are solutions.
One is not to store the energy in the vehicle itself. Large mining and
earth-moving equipment is often electric, and are powered by a cord (a
giant version of a lawnmower with a cord).
I recall reading about a farmer who bought some tracked military vehicle
surplus. He wanted to use it as a tractor. It happened to use electric
motors to drive the treads, and a diesel generator to provide power
(like a railroad locomotive). But the diesel generator was gone.
So, he mounted a big spool on a pole in the middle of the field. The
power cable was wound around this pole. As he drove around the pole, the
cable wound up on the spool until he reached the center. I guess it
worked for him. :-)
