Hi All
In the last few charges our battery when on full charge isnt charging to the full mileage, infact its getting less miles every time. So 2 weeks ago it charged to 115 miles, last week 99 miles but due to the cold i only managed to get 63 miles on this full charge as it kept dropping every time it was driven and now just charged it and it's only got 90 miles on a full charge. Dread to think how many miles we will actually get.
Has any one else had this problem please?

All EV are like this.
In coldest times i manage to drive 140km at once or 120km once single distance of 30.

Hi Kiwal
I would be happy to get 140km but im lucky to get 95 at the minute.

It's not a problem it's a fact of life with mx30's. Check your info on steering wheel to see what your average driving mile per kwh is. At this time of year it should be in the 3. something range. Combine that with cold weather and a myriad of other factors and hey presto shorter miles per kwh. As I have stated already I am now chilled about it, realise its not a car issue it is what it is and just get on with it. We started with 124 range and that was already low so come this time of year its only going to get lower. I just shrug my shoulders and get on driving.

See this Norwegian report. Combine that with possible use of heater etc.

Study: EV Winter Range Loss Averages 19%

The Norwegian Automobile Federation put 20 EVs head to head in freezing temperatures.

Hi Kiwal

I think your getting confused between miles and kilometres…….. You are correct though, battery performance drops in winter time. Ours currently goes to 106 miles on a full charge. To try and combat it I stay off motorways and dual carriageways and use the brakes as little as possible,using the regen to slow me.
Im hoping I get the full 126 miles back in the spring!
Also, I’m not that fussed by ‘fast chargers’. Unless there’s little or no range left I charge at home or the 7kw free ones👍

@Michelle - I think these are some very low numbers for miles / kilometers distance in winter time.

I do not know the weather in GB at the moment, but I do not remember it as very cold or cold as our friends in Norway, Sweden and Finland have.

We live in Denmark and have recently had temperatures in the range -5 to 10 degrees and our average consumption during this period has been 17.5 KWh per 100 km. (28 KWh / 100 miles). This is what is displayed on the consumption display in the instrument cluster (has not been reset for 2 month now).
However, I can see that if are charging up to 100%, the possible distance will usually be just around 180 km. In summer it is between 195-215 km.

I recently spoke with another owner of an MX30 and they drove significantly fewer kilometers than we can, so I have got the idea that there maybe are differences between the individual cars. It is probably quite essential always to have the latest software updates installed.
But it is still strange that it seems that there can be major differences in consumption figures for 2 identical cars driving in the same area. Yes I know - the driver and driving style does matter

Steen, as does the terrain, heating, tyre pressure etc.etc. The list goes on as does conversations about range during winter months. There are too many variables to say what you should or should not get. I think we are too quick to jump to conclusions about "do we have a problem" rather than this is what we were given how do we make the best of it. Sure there will be the very occasional car where there may be a problem but in the main we have to recognise the limits of this beast and try to tame it as best we can. If owners genuinely think they have a problem contact the dealership but I bet the dealer will say what do you want us to do...we can check for error codes but....its winter, its electric, it has a small battery..no Mazda technical issue reports and your s/w is up to date.

It's new to a lot of people so we need be patient, adjust our driving style with the car, recognise the road and weather conditions and the limitations of the mx30 and then just be accepting and chill.

Rant over...it kept me away from strictly come dancing thank god!

Alan, Well said - and then we'll close that topic

... at least until tomorrow

 

[Allen]

Car will not charge at a higher rate than 7kw even when using a fast charger and don’t know why

 

[Thebriggie]

When you say fast charger I assume you mean the dc charger 50kw plus type that plugs in using ccs connection, is that correct? (The mx30 has a 40kw dc max limit and a 6.6kw ac limit)

If dc charging at what soc are you starting at?

[M1nty]

This is my 1st EV and I'm confused by this thread. I realise there's all sorts of factors that might limit actual mileage achieved, but I expected to consistently achieve the full mileage once a full charge was complete, and then only see that vary once I started driving!?

 

[Thebriggie]

No, the full charge takes into consideration your driving history and calculates estimated range based on that. The confusion around 100% should = 124 miles range each time is not based on real world usage unfortunately. So each time you drive the range per mile, which depends on loads of factors, will be stored and that history average will be the basis for the estimated range calculations after charging

p.s welcome M1nty. You will enjoy the car and recognise, as we all have, that every day is a school day 🏫 with ev's in general and especially with the MX30

Alan

 

[M1nty]

I see. .. Seems the wrong way round to me but if I'm understanding you correctly Alan, if I alter my driving style & the conditions are battery perfick etc., I could potentially get many more miles from a charge than the dashboard estimates at the point I detach the charger?

Thankyou for the welcome!

 

[Thebriggie]

M1inty, you are correct re improvements. As you learn to drive the car with the paddles, less right foot pressure etc. etc. and with fair weather you should see the mile's per kw improve on the dash. Practice it on any regular journeys you make to see what works best for you. Aim to get to the high 3's or early 4's but don't stress if it's lower as terrain, as I know in Edinburgh, can screw your best attempts. Short burst's at higher speeds on motorway or dual carriageway's can undo a lot of good work. If you get higher👍 but chill if you can't.

I prefer the way estimated range is calculated as it is based on reality and helps improve driving and sets realistic range

Alan

 

[M1nty]

Alan, I'm not with your "high 3's or early 4's"? Presumably there's no value in using the 2x paddle settings above 'D' as they'll sap more energy (even tho' the book recommends using them up a hill)? I can understand how using the 2x paddle settings below 'D' might give more regenerative power back down a hill, although technically that would give free miles on top of what one might be achieving with a good wind etc? (Which I'm not knocking at all, but that feels like outside the scope of this discussion? 😏). Frankly, why can't Mazda enable the MX-30 to make the paddle decisions automatically, or at least give the driver that option?! 😖

 

[Thebriggie]

M1nty, let's start with the 3 or 4. Start the car and press the info button on the steering wheel. Scroll through until driving info mi/kwh shows in the middle (mine is currently 3.8...bloody hills). That indicates your real time driving efficiency. I leave this screen on to check how far the grey bar goes up and adjust paddle/accelerator accordingly to achieve best possible efficiency.

The reason mazda has went for paddles instead of automatic regen when you take your foot off the accelerator like some other ev's is, I believe, to give you more adaptive control and better driver involvement. Stay on D if you want but for city driving down 1 or down 2 works better for some on this forum. 1 up or 2 up reduces power requirements going uphill as you are lowering rolling resistance i.e the car is not "fighting" itself. Also if you have momentum paddle up helps maintain that momentum on level surfaces. In the end its all down to personal preference there is no right or wrong way just what works best for you. Try it out as I do recommend at least giving the paddles a go. Watch the charge purple section on the left of the dash and try to stay as close to purple as you can or try to not go over two segments white

[seasidebaz]

I just leave it in 1-up now, seems the most efficient. You can check by driving somewhere with constant pressure on the pedal and flicking between the settings - 1-up is lowest power consumption in all situations.

Fun story, my average efficiency went to 44.6mi/kWh this morning, I used zero battery or miles on a trip that would normally use 2% although went back down to 5.1mi/kWh afterwards

[Thebriggie]

Baz, with figures like that I assume it is flat terrain and warm🌞🏖..I can only dream of that number....what's does the range estimate look like with that efficiency?
