They absolutely do. And already have operated at much higher temps since they have been deployed.
Edit: I did a quick look on plugshare and the RAN site in Wickenburg, AZ near Phoenix has been online since at least April. Its definitely gotten hotter than 40C there over the summer.
The temp ratings should only relate to being able to operate at the continuous 650A rating. They will derate as the temps go down to -40C and up to 55C.
I would say it's gouging if the companies were raking in massive profits, i.e. oil companies pulling in billions in profit each year. EVgo has not yet turned a profit.
The cable cooling system on V3 is embarrassing small. I've seen gaming computers with bigger radiators and fans. V4 radiator is roughly 3x larger eyeballing it.
Higher power charging = more heat. Too hot = vehicle damage and worse. Rivian put in a safety measure to keep things from getting too hot which also prolongs the life of all the parts. How come some other cars don't reduce charging power? Maybe they don't take safety as seriously.
Keep in mind it's all a balance of time and money. The Rivian team has only opened roughly 20 new sites this year, but converted over 60 existing to be open to everyone. Rivian did have a small round of layoffs about a month ago, a reduction of about 1% of the workforce. So, they are watching...
That pontoon boat is about the equivalent of towing a parachute. Aside from that, I'd check to see how dirty the radiators are. Depending on where you live, they could be caked up in bugs.
Could you repeat the test, but standard drive mode and drive ultra chill. In city driving, I don't expect conserve mode to save much energy as you're constantly accelerating and braking. The energy saved in city driving is minimizing how much you accelerate and brake. It's constant speed driving...
You remember when Elon fired most of the Supercharger team? He obviously doesn't care about them. Tesla has a solution, fire Elon.
How about support all the hard working people on RAN team.
