never mind Southern Europe.

I suspect they mean Arizona-scale 'hot', not Bournemouth.

Most EVs have active battery cooling so they can manage battery temperature.
If it's hooked up to a charger I expect it to do that. If it's not on a
charger I don't know whether it will expend some juice to cool the battery
while parked, maybe there is a setting for that. In Arizona when it's 40+C
ambient every day in the summer, cars can get up to 70C in the sun. That's
the sort of thing that's not good for batteries - getting them up to 40C
isn't a problem.

Heat makes it worse, but they do still have EVs in Arizona and they last
well enough.
