I have leased a new EQC premium. The battery (hence mileage) drops few points overnight. I have seen this every day and in last 2 weeks on average 5-6 miles have vanished overnight. In 10 days this amounts to 60 miles which is significant.
Does any EQC owners throw some light? does this happen to all cars? Is it that car using some battery to update/send data regularly? Is there anything I could do to prevent battery drain? As a very new owner I don't know much of the functions. Thank you for any advice you may have.

Hi, I’m a new EQC driver too and I’ve noticed this too, however the biggest problem for me, and this makes it even worse, is the poor maximum range? I’m getting it saying max range on a full charge of 175 Miles but it’s not even doing that, despite me driving very carefully in max range mode! What sort of range are you getting from yours?

Hi Jhodson....I have the exact same concern. New EQC, displaying circa 170 miles on a full charge, and lucky if I get that even though I am driving very conservatively. I know that range is lower in colder months.....but it’s 3 degrees Celsius out there, not -50!!!

Yep, exactly the same here. Full charge says about 160 and drops 5
Miles overnight when not moving!
cant help but use heater and radio really. Would internal display lights going off help?
It a just poor range. weird thing when it was delivered, on a truck, range did say the brochure 220
- so it MUST be my driving after all?!

Checked with Merc garage and was provided battery charging is good with no fault.
I was told that EQC is clever enough to know style of driving😇😡 and predicting driving miles. If drive on motorway may be high. Absurd.

I bought EQC for reputation of manufacturer and advertised mileage. This charging absolutely contradicts advertised mileage.

Hace you tried to read the range with the heater off? It adds around 70-100 km of range when you switch it off and reduce it for the same amount if you switch it on.
A suggestion: pre-heat with the app and use only the site heater when driving.

Still charging should show 250-290 miles and depending on driving style and using other gadgets or heating, the charging power should go down accordingly.

I am concerned that there is a big discrepancy to reality and false advertisement. every couple of days when charge goes to 50 miles, it is worrying about charging.
how can this be carried forward to Benz central team collectively?Is it not a grave mistake choosing Benz vs Tesla and other brands?

Any suggestions.

When I add petrol in my previous BMW car, I see certain travel distance displayed on the board. Depending on my urban driving, heating and other apps, driving distance recalculated. If drive on motorway, driving distance calculation is adjusted accordingly. So I know where should I stop for re-fuelling.

whereas in EQC from the time of delivery, for full charging travel distance is calculated 163 miles. I can’t say my car predicted my driving style even before delivery!

Hi. This is the question that I just posted. I’ve had my EQC Prem Plus for a few days now. With 50miles on the clock I have topped up the charge twice using the 3pin charger and achieved a max charge of 202 and then 191. Any ideas why? Surely if Mercedes advertise a max range of 259, we should be getting much closer to that. Unless, this can only be achieved with a faster charger..?

I am begining to think its all a con , just like diesel gate , who buys a 75 k car to drive without the heaters and radio on to save range miles

I’m beginning to feel the same way. 4th and 5th charges of my EQC achieve a max range of 160-165. I too believe that driving style is separate to us being able to charge the vehicle to its maximum achievable range of 259. How can there be a discrepancy of approx. 100???

I bought my EQC 400 in August 2020, we live in the northern parts of Sweden. This summer I often got a consumption that indicateded a range of 263 miles (423km).
The best I manage to get was on a 162 miles round trip, the calculated total range with maintained consumption would have been 287,5 miles of a full battery pack, that day was sunny and +21 degrees Celsius.
Now when we have winter here the range has dropped alot. It is around 160 miles as you all seem to experience. Temp has been around 0 +-3 degrees.
The car has 2 PTC Heaters and 1 heatpump for heating both cabin and battery.
I think that the car is using alot of energy to heat the battery alone, this could be a precaution from Mercedes to "save" the battery from degradation.
These past days we have had temperatures in low -20 degrees Celsius and the calculated range has dropped even more. Its down to 132 miles on a full charge.
But I've seen that the car is calculating depending on the temperatures and driving style.
My conclusion is that the heat pump is somewhat inefficient and the car needs to use the PTC heaters to much.
EQC has a great range in the summer when you keep speed below 55 mph, but poor winter range. Mercedes should look in to the programming of the heating system and try to make it use the heat pump more and the PTC heaters less, and they should implement some cabin circulation instead of only using outside air wich is colder. Mixing both cabin and outside air for a more efficient cabin heating with less energy.

My dealer has recommended to reset the MBUK audio head unit. I’ve done it today and my battery capacity went up to 220. I’m confused by it all, especially as the car is now saying 220 and the app says 187. Surely they should be saying the same thing? Not sure which to believe if any. Also, fast chargers we are only getting 40kw on a 50kw charger, given the battery is 80kw, again unsure why it’s not giving the full 50kw. I’ve tried on different chargers and never got above 40kw, on a long journey speed of charge is essential so not feeling hugely confident at the moment.

Ade, how did you reset the MBUK audio head unit?

Hi Ade. It's a bit fiddly, but I think you're muddling up energy and power numbers. 85kWh is the energy capacity of the battery. 110 kW (no 'h' for hours) is the maximum power that can be used to charge.

I have had the EQC for 2 months and my range always around 180-185 miles when fully charged. if you don't use the heating the range goes up to 225-230 miles, but not using the heating becomes a task when its cold and you need to de mist the wind screen. also for such an expensive car to drive without the heating or eventually AC seems a very strange requirement.
I also loose some miles overnight or even when you park for an hour or so, at my return to the car the range has dropped.
I have also checked the range decrease vs the miles actually driven, and despite not always using the heating, driving carefully ( it does take away any fun !) on E or MR in D Auto, the actual decrease of the range is higher than the miles driven.
When I checked carefully the actual range equates to approx 140/150 miles of drive.
Do you all have the same problem ? or is there anybody that gets more than 200 miles range ? and if so how do you do it ?

Some of this depends what you mean by "range". If you do a lot of short trips the total mileage acheived for 80kWh will be a lot less. That's because the energy required for repeated start ups, especially in winter, is high. If you see "range" as 'how far could you go on a single long trip without needing to charge' it will be a lot higher. Unlike the stereotype of electric cars c. 5 years ago, I find the EQC is actually efficient on long motorway trips - it should do 200 miles reasonably comfortably in non-freezing weather.

What I do think is an issue with the EQC is the range algorithm. It's overly responsive to minor changes, like turning on the heating. And is set very conservatively. I understand why Mercedes do this - better to have people worried about the range algorithm, than actually getting stranded! But I wonder if they could tone it down a bit with a software update.

I don't take the algorithm too seriously anymore - or least not till it's showing 30 miles or less and you really need to plan where to stop. Generally the car will always go as far as I would want to drive between coffees (2 hours max).
