I said this car needed a 15kWh battery.

That's 88.5 kg (or 192 lbs) !

A metal hydride battery of this weight would - according to the
engineers at Honda - contain 6.2 kWh of energy and have a range of
27.9 miles.

Honda's numbers are simply out of date. They won't be using those numbers today for
sure.

NiMH technology is taking huge strides. Capacities have tripled and more since
introduction for no added weight or volume.

Graham

Please provide references for these outrageous claims? In case you
haven't noticed Graham each specie involved in a reaction has a
particular atomic weight, and each reaction has a specific number of
eV per reaction so there's an absolute lmit to how much energy you can
put in a battery. Now,'old style' batteries as you characterize them
were well over 80% toward that limit. SO WHERE DOES THE 3X INCREASE
IN POWER DENSITY COME FROM?

Nowhere, because it doesn't exist. You're just flapping your jaws and
don't know what the heck you're doing saying or thinking.
