Hi all,
Hope this post finds you well. I recently got myself the EQC PP (brand new). When I got the vehicle the dealership informed me the best range they could achieve was 238. I have attempted to charge the vehicle using the 3 pin home adaptor twice; first time I could achieve a max charge of 202 and second time 191. Does anyone know how I can achieve the advertised max range of 259 (or anywhere close)? Is this only achieveable via the faster charging options?

I also note that if the vehicle over forecasts how much range is required to heat the vehicle if you are to switch on the heaters when you jump in. This reduces the range by approx. 30miles. I’m told the trick is to switch off and back on and the range resets itself and gives you back the 30miles range. Seems odd. Does anyone have any info on this?

Finally, Im told the 3 pin charger is not good for the vehicle battery. Can anyone she’s anymore light on this.

Hope you all had a great Christmas. Many thanks in advance.

KC

Hi
Also just purchased same car , you will never get 259 miles , I'm just waiting for home charger to be fitted free of charge which will provide 7 kw of power at home opposed to the 3kw with 3 pin in real life unfortunately 160 miles is the norm , a total disappointment !

Hi thanks for your response. 160, really? How is it the dealer managed to get 238 when they charged it for the handover? They made a big deal of showing me that they managed to get this range. I knew before purchase that I’d only get 180-200 miles from a full charge (despite the reported range being 259), however I was not aware that the charge range would be 160-180..

I get full charge range 163-169 max. I am yet to hear anyone getting reported range. Dealer advertisement is humbug. It is an absolute disappointment as I don’t have the pleasure of driving. I can’t drive or plan a journey at my decision as journey required charging for few hours.

Thanks. Can I ask how you’re charging it? Are you using the 3pin, 7kw or rapid charger? Is there a case that needs to be brought to Mercedes for false advertising?

Same here, 160 max miles on a full charge. It seems like you don’t have access to the full battery? Has anyone contacted MB for response? If be kern to hear what their response is to the 100 miles deficit. Also, has anyone used a rapid charger and got 50kw speed? We used one the other day and got a max of 31kw, if we went on a long journey and got this speed of charge and the reduced mileage at full charge, we’ll be sat at the services for 40 minutes or more!

Hi. I’ve not contacted MB yet. I wanted to get more facts before I reach out. I spoke with a dealer and they mentioned the cold weather will impact what range we get on a full charge. He said 160 is perfectly normal in 1-2 degrees climate. Others have said they would expect min. 200 in these conditions. I want to use the rapid charger to see what range and speed I get before I draw any conclusions. Will we need to wait until warmer climate to achieve a max range of 200+, or is there a fundamental issue here??

Hi, 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.

Hi Lars. Are you an engineer? Do you know what heaters they’re using for pre heating the vehicles. Hoping it’s the more efficient option you mention...

Hi Ade. Did you use the car navigation to get you to the fast charger?
I went to a fast charger and plugged in only to get about 31kwh. The next day I used the sat Nav to go to the same charger and as it preconditions the battery I found I got 80kwh. It was about 4 degrees C outside.

Hi, yes I did use the nav to get me there. So you got 80kw from a 50kw charger???
Sorry. Used a BP charger that gives up to 150kwh. I thought I might get 110kwh (the max the eqc can get) but I ended up getting 79-80. I thought that was pretty decent.

Ah okay. From what I understand you will never get more that 80kw as that’s the size of the battery so you’ll never go more than that, so to get the full amount is excellent!

That’s interesting. I’ve definitely seen a few reviews where the presenter stated that 110 was the max. Whether that’s just a figure in perfect conditions or not I don’t know and I haven’t seen it published anywhere by Mercedes.
ive just started using google maps on apple CarPlay as the Mercedes Nav was a bit crap with some of the suggested routes. It’s a bit of a bugger though as google maps won’t talk to the car if you set a charging point and therefore the battery won’t be preconditioned. In weather like this, it seems to be crucial to getting the best transfer.

Hi Gus, can I ask what range you achieved through the rapid charging?
Separately I spoke to Tesla today. They claim that all manufacturers have the same issue re. Colder climates results in us losing range and that more efficient heaters is a possible solution. He claims Tesla’s lose 20miles only in cold climate. Thats 20miles vs. The 100miles were losing on the EQC. Surely the motor regulators would have enforced these vehicle manufacturers to be more transparent re. Max range? I would have expected them to push manufacturers to publish two sets of ranges for cold and warmer climates. I can’t help but feel a little cheated here. I may be being a bit naive but in all my research (and I did a fair bit) I had not come across anything that said in colder climates the range would be more like 160. I’m keen to hear how Nissan, Toyota and others deal with this. Same issue? If yes, then this should be well publicised and transparent.

I didn’t get any real difference on the range from the rapid charge. The only time I’ve seen a rise in the expected mileage is when the temp rose to about 7 degrees and the mileage went from 179 on 100% to 208 miles.
My local dealer told me that many manufacturers have the same issue with cold temps but he didn’t tell me how much drop in range there was with others.
I am slightly nervous at the prospect of using the vehicle for a long drive in the cold. Interestingly I read an article about Tesla and something they have that means the battery range isn’t impacted as much by cold temps. The article didn’t go into detail but I can totally appreciate the benefit of any technology that protects the range.
I don’t know where we would stand on taking it further. 100 miles off the published range is pretty substantial in my opinion but I’m not sure who would listen and action.

The last major scandal to hit the motor industry was the diesel gate. Could this be the next I wonder?
I wonder what my dealer did to achieve 238 on handover. Only for me to achieve 202, 192 then 160.

One thought on this. Range only matters obviously when you need to do a long journey. What I notice is that the efficiency is very low on short cold trips. Sometimes down to 1.5 km per kWh. And the range estimates seem to adapt to that kind of use. But once you do a longer trip the efficiency increases a lot - trebling or more.

It's reasonably intuitive - the car has to use a lot of energy on the initial heat up and start (which is beautifully fast and comfortable by the way!). That means the energy per distance is very low on cold short, slow trips with a lot of stopping and starting e.g. shopping or school run. But that isn't a situation where range matters. Once you go further, it usually becomes much, much more energy efficient. I find around 4km per KWh with smooth driving.

Also a few earlier posts are confusing energy and power. The battery can store 85 kWh of energy. But it can be charged at a power of 110kW (with no 'h' for hours).
