I would agree there. During the trip to Devon, we did find some fast chargers, and arrived at one quite low on range, the charging flew to begin with, but did slow up.

Faster charging would certainly make things easier!
that's the next generation of batteries. low temp resilient, flatter or even flat charging curve, 500kW+ charging, non flammable, much higher energy density.

At the risk of labouring a point….

I was fiddling with cars today and thought I’d do a little experiment.

It’s quite possible that the small rise in EV brake disc temperature was radiated heat from the tyres and that the friction brakes had not been used at all (which would also imply no brake wear or dust pollution.)



Before driving;

EV 11.4



ICE 11.9


After driving:

ICE 48.5



EV 15.8
Interesting that the EV's 'after' tyres are much warmer than the ICE's. Presumably a consequence of the extra weight sitting on them.

Or just you mid-reading a thermal image…

You have to really measure them specifically, the colour map is not accurate

I’ll have a go next week when I have time
