Move to Scotland? Not as hot and the motorways aren't blocked? Sorry, couldn't resist!
Um, I believe AC does drain the battery quite a bit (remember it also hammers your ICE fuel consumption too). If you were low it would be a bad thing. But I guess, like with a car, you wouldn't want to travelling too low on fuel?
But I haven't done it, so can't speak from experience. Larks, or WW or anyone else, how is slow and AC on (presumably) affecting your battery?

I’d have thought that the battery doesn’t drain much when you’re barely moving, unless you’re using a lot of heating or air con.

big, haha!! But, yes clearly car / driver / driving mix dependent. I'll try and keep the size 6s under control though, point taken 
I'll keep watching the average. Should tick down a little as the weather stays warm I suppose but dodging to the shops for the BBQ stuff won't help!
carp - you'd be in the same situation as if your ICE vehicle were running low, wouldn't you? Rubbish to get stuck though, sorry to read that

Sorry, yes, WW much more polite than me. Sorry you were stuck on motorway(s), that's always sh*t. I used to commute M3, M25, M11 and back every day. I have spent a lot of time stationary or crawling on motorways in my time.

Actually it was probably A3, M25, A12, but M25 is enough of a motorway to have sympathies. And I did the full M25 in a day. Usually anti clockwise, both ways!

I was using my heater over winter because I refuse to drive a cold car and was preheating it 10 minutes before leaving and, with the ambient temperature I was getting between 220 to 230 miles to a charge. But take today where I haven't been using the heater or air-con recently and today's charge showed 265 miles.
Bear in mind the charging also takes into consideration on how you have previously been driving and also I'm not light on the accelerator pedal.

My handbook recommends using the heated seats where possible in winter instead of turning up the heater.
I’m assuming it’s the principle of only heating the bit that’s needed.

I think slow driving doesn't really cause efficiency problems as the energy required to move the car forward is less at lower speeds due to air resistance impacts growing exponentially with speed (terminology may be wrong there!), so a slow plod through traffic jams would be ok for a BEV. A ICE car burns fuel when stationary when the engine is ticking over, the energy use when stationary is far less in a BEV.
Obviously, air con or heating use would change that a bit so sitting icy cold in a traffic jam would use the battery but not enormously.

Yea it's recommended to use heated seats and steering wheel but screw that I want to be comfortable when I drive.

Well, aircon won't have any effect on this ICE, because it doesn't work. Stupid contraption.
