Excellent charge at Perth Ionity this morning. Worked out that what with the solar charging at home and loss of charge during the holiday that our Inverurie to Edinburgh airport return trip will cost £7.

That is astonishing considering the high ambient temperatures and the high SoC!

Most BEVs charge quickly only when they’re in single digit SoC and while their battery is in a very narrow temperature window!

I've found that our Zoe rapid charges faster when it's hot as well, and the economy in this hot weather is astonishing, instead of around 5 miles per kWh it was getting about 6.5 miles per kWh on a shortish trip earlier today. TBH I'm surprised, as the aircon was running flat out, as it was around 32°C outside at the time.

It was so fast we literally went for a 5/10 minute walk, unplugged and went on our way. Dropped car off at Airpark Edinburgh with 204 miles range on it. Interested to see what the range will be on our return due to vehicle consumption and lower temps. Anything above 160 miles and we will drive home with no further charging. 270 miles for £7 is quite good considering a gallon of petrol is about £8.40. 324 miles per gallon fuel cost!

Perhaps its also because the air is less dense.

Some of it undoubtedly is, but not enough to wholly account for the improvement. I think there are some other factors at work as well, perhaps the battery losses also reduce when it is warm?

I doubt that. in these things the Gas laws apply... when all calculations are done in Kelvins, i.e. degeees above absolute zero, so 20 C and 30 C (even 40) arent significantly different... unless viscosity of air falls with a power function of temp!
Maybe your tyres are harder when it is hotter? (but not very likely, see gas law comment above...)

Drag is directly proportional to air density so when that reduces drag reduces. According to this website, https://www.engineeringtoolbox.com/air- ... d_600.html , air at 35°C has a density of 1.146kg/m² and air at 15°C has a density of 1.225kg/m², so that means that drag at 35°C air temperature is going to be about 7% less, so needs about 7% less power for any speed, but that is nowhere near enough to account for the big reduction in battery energy used.

Anything above 160 miles and we will drive home with no further charging. 270 miles (there and back again) for £7 is quite good considering a gallon of petrol is about £8.40. 324 miles per gallon fuel cost!

Charging purely at home and that same £8.40 for a gallon of fuel goes up to 610 miles per gallon. If I can split 50/50 on the EV between our own generated PV electricity and home charging as we have been more than doing the figure becomes 1,220 miles per gallon fuel cost.

Flipping THAT figure on its head, those 1,220 miles at 30 mpg cost £341 at £8.40 per gallon. Crazy eh? I am now looking about for an EV camper van.

I know there are guys here who will beat 1,220 mpg as the I5 only gets about 4mpkW. I am thinking back and in these high Summer days we have been going for a week to 10 days charging purely off the PV through the day with a then small top up from grid as we are doing a distance the next day. I reckon we could easily be doing 2,000 miles per gallon fuel cost in reality as we get 152kWh at go faster rate for that £8.40 gallon and it would take yonks to get through that in these strong solar days. gon the ev!

£8.40 per gallon really puts the price of fuel into perspective! When I was still at school I had a job at a local garage in the evenings, working the pumps. I remember being given some new price stickers to put on the pumps when the price rose to just over 5s per gallon, or around 25p per gallon in new money.
