I believe it. It makes a huge difference if the climate control is turned off. It has been brutal here in Iowa. Actual temperatures have been -15 to -19 the past 3 mornings and stayed below zero basically the entire time. Wind chill got as low as -49. Ungodly.

From what I'm reading, Tesla owners in Chicago seem to be having a different experience. Stranded, disabled Teslas filling up the Supercharger parking lots. Not charging and blocking the chargers for others. Owners coming back in ICE cars to stay warm and keep an eye on their paperweight just sitting there. No help from Tesla apparently, either. Stay home unless you really have to go somewhere.

If the car is preconditioned or at normal temps and low battery I get up to 206kw. However, the EA chargers that seem most consistent for me are the 150 kw ones that are half CHADEMO and CCS. Those seem to most often be in fully working order and delivering max charging which is usually 160. The latest EAs (the skinny ones) work very well to full 200 plus..

The way I read the above is that your car isn't parked 24x7 outside and being battered by the cold, unlike those who don't have a garage where they can keep the battery warm at night and wake up to a dead battery in the morning. How many hours in a row was yours subjected to the freezing cold? Did I misread?

Thats why it was the first time it has ever been truly cold soaked in the 2 years Ive owned it. I was on a road trip and the car was at -10 overnight. Furthermore, it wasn't preconditioned before charging. In effect the worst charging conditions possible, yet the car was charging at 90 KW almost right off the bat. The only time the car has been supercold was when I left it In MN for 2 weeks in Jan. But on that occasion I didnt charge because I parked it with a full battery. Nicely, in those 2 weeks of sitting in the bitter cold the car lost virtually no charge from parasitic losses, another amazing feat. As far as cold weather EV design, Mercedes has done its homework as good or better than anyone else. Completely different from the many stories of cold bricked Teslas that litter the net.

EQS Sedan
I really enjoyed reading this thread.... I'm an ICE engine guy with a Bentley, C8 Corvette and Ferrari in my garage. I added a EQS sedan only because it was such a deal and included 2 years of FREE charging. I never considered a Tesla or Rivian even though many of the car 'rags' raved about their technology. Hey, Mercedes has over 100 years of experience building cars.... the others out there measure their experience in months and years. Bottom line, I believe I made the right decision not because I'm smart but just because of dumb luck. Once again, a blind squirrel finds an acorn!

not trying to defense Tesla as I dont like Tesla, but for all EV if battery is cold enough, battery won't charge. pre-condition your battery before go to DCFC is the key.

My wife just got back from a round trip from Des Moines to Chicago. Just reporting her results, as I think this was the worst case scenario anyone will see for an EQS. Temperature was between 5 and -15. Returning home driving into a 15-20mph wind. She averaged 1.6 miles/kwh. Maximum fast charging rate was 86.

Magic sauce: If the car has been sitting out in the cold, use the cabin preconditioning before you go on your trip. I think it also heats the battery (not sure) Again, on my little test the car was -10 all night and the charger was only 5 miles away, yet it was charging at 80 in about 5 minutes.or so. Given that around the upper midwest by far the most common chargers are 50kw, 80 can be a luxury in the best of times! Plus, it will hold 80kw all the way to 90%. Not blinding fast, but acceptable given the conditions. My car has never failed to DC charge at any temp, and it is often well below zero around here. As far as I can tell, MB has the cold weather operation down pat. Still less convinient given the physics but the vehicle still does its job with aplomb. One thing that does irritate me are the public level 2 chargers, they are virtually all 6kw that splits to 3 (110V) if both taps are being used, they are essentially useless and just for show.

Can anyone verify how to precondition the battery? The car is set to "automatic", but how does it know when I'm going to charge? Based on a NAV entry? Do you enter a charger destination in NAV, or spring from "find charger" in NAV? Also, has anyone recently been able to plug and charge seamlessly at EA?
