What happens if he needs the heater and the wipers etc as well though?

On my EV there is no heater and the wipers and lights etc run from an
independent auxiliary battery so wouldn't affect the range as such,
especially in the dry and daytime. ;-)

So on a long journey in the rain the wipers and lights would pack up?

No, in general the aux battery under average load would outlast the
traction batteries.

What's the capacity of the aux battery?

I think is was about the size if a larger SLI battery but because it
was a cyclic use type it was probably lower capacity (so say 40Ah)?

Normal wipers draw between 5 and
10A at 12V so you'd need a big ass battery to keep then working all day
long.

You would indeed, however, this is a an old skool lead-acid powered
and non aerodynamic design we are talking about here. ;-)

However, it would take me to and from work (inc home lunchtimes) for
about 2 weeks on one (50p) charge so ... ;-)
