Just wanted to share my experience this past Sunday with my 2018 Leaf.
The car has the Nissan passive air-cooled 40 kwh battery pack.
Left Burnaby with a full charge. Made it to Hope with 20% battery left and the battery temps at 3/4. This was all highway driving at 10 km/h over the speed limit on the cruise control and AC on.
$5 of charge time at a BC Hydro DC fast charger and the battery was just before the first red mark and showing 50% battery.
Hopped on the highway with the intentions of stopping in Chilliwack for some more DC fast charge. Got to Chilliwack and got in about 15 mins of fast charge but it was too hot and we decided to head back to the highway and try to hit Coquitlam Superstore for a quick top up charge before heading home.
We were approximately 65 kms from the Coquitlam superstore with 62 kms of range left so we stopped in Abbotsford for a quick top up. The battery was just at red and charging at 16 kwh.
After another $6 of charge time, the battery was now in the red but we had enough range to make it home.
Getting on the highway, everything was fine till we passed Langley and into Surrey, the highway speeds pushed the battery temps deep into the red and I got the high temp warning screen and the power to the car was deeply reduced. I could go highway speeds but there was no acceleration. I limped it all the way home with only 7% battery and 19 km of range.

Overall, I still love my Leaf. Makes a great city car. I think if we had the plus with the 62 kwh battery, we could have saved 1 or 2 of the charging pit stops. But definitely in the heat, the passive air cooling isn't enough cooling on the batteries.

Did anyone go on a road trip in the Tesla during this heat wave. Would be interesting to see how people's Tesla's faired in the heat and high speed charging.
