Not sure why this is happening or if anyone else experienced this. I’ve had my 580 for around a month now. I always charge it to 80 percent of battery when I charge it. The screen always reads that I have around 315 miles. I charged it last night and it’s only reading 270 miles at 80 percent. I’ve left charger in all day today just to see if it wasn’t truly at 80 percent. Anyways it’s still showing 270. It has been warmer the past few days out here. Can that have anything to do with it.? Just curious if it’s normal or if it could be some issue that could be starting. Thanks !!!

Not sure but I think it is dynamic. It is meant to be estimated range, so driving pattern and weather can change it.
Thanks !! Makes sense. Guessing it’s change of weather then and I won’t worry. Had so many issues with Tesla X and ipace at the beginning so guess I’m just waiting for something to happen. Lol.
Hello, Yes it’s normal, I live in San Antonio and I charge at 100% at 9.7kwts and get 425-450 miles. Cool days I get 380-420. Anything above 22kwt charge my mileage gets reduce to 350 miles. Fast charge is bad for EQS batteries.

Interesting that you are concerned about fast charging hurting the high voltage battery but still always charge to 100%.

Indeed, it is certainly universally recommended to only charge to 80% for daily usage, and to charge to 100% before a trip, and then leave immediately. It is thought that this will prolong the life of the battery.
Yes, but the key is to slow charge (9.7 kwts). Think like this fishing boat uses gel batteries and have to be slow charge for them to last it’s cycle. Most batteries including drills batteries they don’t recommend fast charge. 100% will not damage batteries. I’m looking for the article regarding EV charging. There are two manufactures of batteries for EV, LG and Samsung, but since the research was done on 2019 they might have more. Remember fast charge creates heat on batteries, heat is bad 107 kwts batteries. I’m not expert but I base myself on life skills and work realed issues with battles.
I am charging at home with a ChargepointFlex charger and 50 amp breaker. The system only lets me charge at 3.97KW hours and I am set to 80% for the home profile. I typically get at 80 % a 325-330 mile range with the occasional 100% charge I can get 408-410. I have never seen above the 410 range. I am in the DFW area with normal temps around 70 degrees. I wonder if the variance is due to each individual battery characteristics. IE: my car is not the exactly like your car and we should not expect consistency within our group.
Hi, I’m in San Antonio EQS 450 plus and I have the same set up. Keep in mind when you sign up for Charge point Flex charge you give them access to what kwts your EV can be charge depending on the grid demand. After 6 pm I can charge at max 9.7 kwts. I keep a ledger for chargers and I keep temp, wind, time of charge and length of charge. My EQS petty consistence with the analytics of ledger. I wrote tread about a trip that I took to the valley and this is why I recommend that you don’t use anything above 66kwts.
I hope this help you, but most important use the highest level of degeneration you will use the most of the batteries. I rarely use the brakes.

Just saying....your opinions and recommencdations are not consistent with what most EV manufacturers are recommending for battery life. Not disparaging your life experiences....but you might consider reading more about manufacturers and owners recommendations as to battery maintenance and care, including what MB states about it in your owners manual. 100% daily charge is certainly not recommended, and past experiences from other EV owners are not optimal with that formula. YMMV.
I agree, each manufacture has different recommendations. I’m learning from you all and I do research because I don’t want bad opinions. But when I purchase my EQS the dealer show me a power point from Mercedes’ on the sales of EQS and I quote “ you can charge your EQS at 220kwt at 15 miniute charge at 80% , like u said this not recommended by the owners manual. But Mercedes dealers are telling owners different and is coming MB. I strongly disagree with dealers and MB power points. Austin, Corpus Christi, San Juan, Boerne, Texas have the same PP. The manual for the EQS 450 on page 196, Para 1, 3rd bullet statement quotes " Charge the high-voltage battery on average to a condition of charge of 80%. Beyond a condition of charge of 80%, the charging time is considerably prolonged." but it's does not say anything recommended or not recommended or damage the state of batteries. Matter of fact it doesn't even talk about the difference of L2 or L3 chargers like MB PP. It does talk about what i mentioned before about ChargePoint L2 or other brands chargers charging at 10kwts, See: Function of the condition of charge display in the driver's display. But i did see this to be fair. I Can only talk about ChatgePoint chargers and it is set for possible time charge at 95 % charge and then it shuts off. Like I said, I posted a trip addressing these concerns to learn the EQS, is new, but is not the same as other EV and MB sales personal are giving bad info. I keep an open mind regarding all subjects it's our responsibility to follow up on it and learn. So I thank you for that. I have owned Mercedes since I was TDY to Germany on the 80's. I started to MB on the early 90's mostly Diesels. Love my GMC trucks, currently I have a 2021 GMC AT4 Diesel 3.0.

unless you are going on a road trip 80 percent home charging should meet the great majority of your needs. Most people will probably home charge once a week from 10 to 80 and thats it. That should not disuade anyone from fast charging any time they wish or need to. People who's only option is fast charging should simply be aware that their battery will last less than otherwise. How much? No one knows, my best guess is 20% but that is a guess. If you baby your battery it should last around 200k miles. Teslas lose less than 10% range by 100k miles.
Funny I came on here today looking for the exact same topic!
I usally see 364 miles at 80% but for the first time after charging now see 311 miles. While this was a slow charge, the big difference this time was this last weekend I took a 500 mile road trip and used a super charger for the first time.
Now I doubt my battery actually degraded 18% because I used a supercharger. My guess is that because I drove on the freeway at 75 mph for 500 miles it is recalculating what it thinks I can get from 80% charge.
I'm actually doing the same trip this weekend again so it won't improve, but I will report back after a month of 'regular' driving to see how it changes.
Guys, chill. DC charging doesn't cause any degradation you would ever notice for years. The pack is made to fast charge over and over for many many years. Also stop fretting about the range estimate every time you jump into the car the important metric is state of charge. After a 10 or 15 minutes of actual driving, then check you range, by then it will have the best estimate according to the conditions of your route, weather and driving style. Its a dynamic estimate, thus it will adjust during your trip. A good rule of thumb on a road trip is, if you haven't planned the trip beforehand, ask the system to find you a charger at around 20% state of charge. That will give you an ample choice way ahead of time. You should not be recharging with more than 10% SOC. In that way you can get the most watts in the shortest time. Unlike an ICE car, you dont want to top it off (which takes a long time) on road trips you want to keep the battery in that fast charging "happy place".
Just give it a day of driving around and charge at no more 9.7 kwts to 100% then returned to your normal charging like the instructions from the manual listed above. By the way I just found out that the batteries are the same as Tesla but not the same technology behind it. Either way thanks for sharing it will help other members. I travel a lot but I keep a ledgers for analytics.
Today I drove my 450+ in northern Georgia. It’s a trip I’ve made several times. It’s just over 83 miles of stop and go traffic. I usually average 3.3-3.5 mi/kWh.
it was 85-89F today. I left at a 90% state of charge with a range of 376 miles. I arrivesd at 72% and 328 miles of range. That would translate to a 100% range of approximately 456 miles. I averaged 4.2 mi/kWh. Darned impressive.

That is very impressive! I don't get anywhere near that. You are a very good driver!
I think it is becoming recognized that the 450+ is the mileage star. The 580's have their performance, aesthetic and luxury attributes certainly, and the AMGs are phenominal. But if you want mpkWh, the 450+ is the car. I regularly get above 4.0mpkWh, and my SOC always estimates around 360 miles at 80% charge. Obviously, driving habits impact this tremendously. AC does not seem to impact my mileage at all. But cold weather is a severe hit to the SOC. It is so interesting as we explore the capabilities of this amazing car, to see the differences we each are experiencing. I almost always charge to 80%, unless a trip is planned. I have (knock on wood) about 4100 trouble free miles now, and the experience keeps getting better. What a phenominal car!

As it should be. However the 580 is a nice compromise between the two. Fabulous grunt and excellent milage. I confess if I lived somewhere where snow wasnt an issue. The 450 would make more sense. But I do suffer from leadfootitis.

Leadfootitis is an insidious infection, very hard to control.....I'm working on it, and have been recently fairly successful. However.......if I had two motors.........
hlothery, good to hear that your 450 is doing good. I in the other hand having issues after issues. I asked dealer to order me another 450 before the model changes next year to a 450V. Are you still in SA? I still get lots of warning pop ups. I will like to ask you some questions I think we know each other professionally.

Been away for the weekend. Yes, I live in San Antonio. Don't think our paths have crossed, I got your PMs. Sorry to hear of your troubles. Which dealer in town are you dealing with?
Same as yours, I saw your profile pix. They been real good with me just had a bad production date on it. No one that I know in SA with EQS have the issues that I have. So I know is not the EQS just the production date (gremlin's). Thanks for your respond.
This is probably the wrong thread, but there’s been so many threads about home wall mounted Charge Point chargers that I’m kind of lost. I know very little about this subject. I ordered the NEMA 6-50 type plug because I didn’t know any better when I ordered the unit back in December. Does it make any difference on the speed of charging? Additionally, I thought the electrician was going to install the charger with hard wiring but he instead did it with a plug-in. Does that make a difference on the speed of charging? He did install a 60 amp circuit. The speed of charging is only 3.8 kWt. That’s pretty slow and it takes forever to charge the batteries to 80%. Any suggestions or advice would be greatly appreciated. If it helps to increase the speed on making a few changes, I can have the electrician come back to improve the speed. Thanks in advance.

My circuit has a 50 amp breaker. You should go into the settings menu on the ChargePoint app, and set the amperage to match the breaker on your circuit board, which should have been labeled by the electrician who installed it, then the unit will match the charging wattage to that amperage rating. I set mine to 50 amps, and I charge at 9.5-9.6kW. A 60 amp circuit is pretty high, but you should be able to get the same charging rate I am getting if you set the ChargePoint device to 50 amps. Your circuit can easily handle that, and that is as fast as the EQS can charge using AC power. I also am using a NEMA 6/50 plug. The only difference between that and NEMA 14/50 is an extra ground, and ChargePoint/MB actually recommended the NEMA 6/50 because it is cheaper. My guys actually installed a NEMA 14/50, and had to change the plug because I had already ordered a unit with a NEMA 6/50 plug. Hope this helps.
