Range Real World

[ChrisT]

Just did 95 miles on 60% of charge. Heater on, lights on for half of journey but had turned off all other driver assist gizmos. Mainly flat terrain' average speed 60mph.

So in theory that's 156 mile range though as the battery depletes there maybe less miles per kWh.

Happy with that though' the big advantage over our 30kwh Leaf is being able to do 100miles comfortably before needing to charge.

Charging at Instavolt which is so easy' tap your bank card and charges straight away.

Looked at charging at another site with 350kw chargers, Ionity, obviously that will be 50kw for this car, but was 69p per kwh which is very expensive.

Thats good for this time of year. your m/kwhr shouldn’t alter as your battery degrades - but your range might! ?

I only managed approx 110 miles (102 + about 8 left) today on the M4, driving 60-65 mph. Heater on only occasionally. A bit disappointed at that really. Started on a 100% slow charge, the mileage holds up well for quite some time, then seems to drop 20 miles very quickly.

Weather was wettish, and temps around 7'c..

Hey ho, roll on summer..:-(

 

[Cocijo]

That’s about what I do if that’s any consolation. I see around +40 in summer on the same trip.

I have only been getting around 3.0-3.2 mpKWH. Which I think would top out at a range of 120 miles... But we would need to be cautious going so low... so probably 110 miles.

95miles on 60% for winter is excellent. What's the secret?

What is the optimal speed for EVs?

For ICE it's usually 55mph and getting to there quickly without going over 3000 RPMs.
What is optimal method for EVs?

Stay put in the driveway..............:-(

EV’s love slow town work. I can get 4 to 5 m/kwhr in summer purely slow speed. EV’s don’t perform well at motorway speeds in comparison. Although if you stay below 60mph they’re not bad. 70mph+ and they drain really quickly! They also hate cold weather and range can halve in some instances compared to warm weather ? I’ve yet to achieve what some on here claim to do, but driving style might have a big influence on that too. I tend to just drive and enjoy the car - heating on etc - without thinking too much about range and consumption.

Just wondering if it was windy, that can have a huge effect and especially as this car is high up and not that aerodynamic.

A little add on to my first post on this which I did on the outbound leg of my journey which was 150miles each way. I rapid charged 3 times, twice on way back neither time was above 80%. My experience with the Leaf was the same as with this car which is as the battery gets warmer after rapid charging the range improves. I reckon I was getting 20 miles per bar compared to 14 or 15 on way down.

 

[doctorjee]

The EVs are most efficient at ~15kmph which is less than 10 miles/hr. That's impractical. I have driven MG ZS EV, for a little over 1500km till now and the best figures that I got was ~280km on one single charge (still 5% battery remaining), with 4 adults and 1 child, covered in ~3.5 hrs (there were roadblocks, but mostly at`~70-100kmph).

I have a question though, is KERS 3 better than KERS 1 when you are driving on the highways?

Range not looking great on my new car...
I slow charged the car when got home with it for first time on Friday. Left it for ages so it had finished charging/balancing.
Had 448Volts on display.
Have logged the following after the journeys so far:
8/2 08:30 0c 14.9m 2.4m/kWh = 6.208kWh 428V
8/2 15:30 0c 12.4m 2.9m/kWh = 4.275kWh 419V
9/2 08:30 0c 12.3m 2.7m/kWh = 4.555kWh 406V didn't reset so ignore
9/2 11:00 0c 27.5m 2.6m/kWh = 10.577kWh 395V
So, have done 54.8miles and used 21.06kWh.

Wife going back to work tomorrow, 108miles round trip (just moved and it's gone up from 98!!).

The figures do not look good for our main intended purpose of the car.

I hope that the car does the commute that you intended it for. I have a few range thoughts (you probably already know these but bits might be useful).
i didn’t realise until recently what a massive impact switching off the HVAC has on predicted range. On my car it will add 30miles+ to the prediction on a full charge
From N to E adds a further 10%
i’m not advocating driving with no heater btw!
my car typically shows a predicted range of about 125 in winter with HVAC on in N mode. I average about 3m/kwhr with mixed slow and some 60/70mph driving. Switching off HVAC and selecting E mode this goes up to around 170miles. I find the prediction very accurate.
in summer/warmer weather I add about 30-40miles to the range.
On shorter journeys (under 10miles) in winter I get well below 3m/kwhr
i don’t drive particularly slowly or gently.
High speed work especially in winter will kill range and I’ve been down to 2.5m/kwr on motorway bursts.
it’s nice to know that if you do need it you can squeeze quite a bit more out of the range.

Also in addition to this it’s the amount of heating you have turned on too, if you have it turned fully up it will use more power try reducing the level of heat and use the heated seats, also don’t forget the temperatures over the past few days really make a difference too.

So if we were to get a small heater that plugs into the cig lighter and use that instead of the main heater would this use the 12v battery ? And keep the range as the heated seats does.
Just thinking out loud ?

 

[AbuG]

That would only work if it was more efficient than the inbuilt/HVAC heater, but I doubt it would be.

I'm struggling with range too, as previously reported. Last night I granny charged from 7pm until 10am, which didn't finish equalisation. Car showed 437V and 103m range in N. I then reset the Accumulated Total and the range jumped to 146m in N and 160m in E. I'm wondering whether others are clearing their driving history before quoting range?

Interestingly the low battery indicator only sounded at 22m remaining, which I'm sure used to sound at 30m left. Of course I don't know what range I really had.

I drove my 26 miles to work (3 miles through town and then motorway), arriving with 95 m range remaining, which reduced to 18m after the journey home. Stats show 2.4m/kWh (I drive consistently at speed limit as use ACC). Also enjoyed heating today.

I've done at least 22 equilisation charges since BMS update, and wonder whether I'll ever get the range back?

 

[AbuG]

If your equalisation is not finishing everyweek day then may need to consider rapid charging to 80% and then allowing the slow granny charge complete the rest overnight.

Or speak to your MG service team maybe they can do it for you and loan you a car.

If your equalisation is not finishing everyweek day then may need to consider rapid charging to 80% and then allowing the fast AC charge complete the rest overnight.

I often charge at work during day, and overnight at home. This
allows me two full equalisation charges per 24 hrs. It's taken 3 weeks to get from 429V to 437V. 450V seems a long way away...

No support from MG or dealer, as they can't recover the battery any quicker than me (apparently). I do wonder whether they can drop the pack and charge the batteries directly, without "computer says no"?

I did try that a few years ago in an ICE car. just blew the fuse.

may not be the same now tho' kinda depends on the heater...............

Yes I looked into this for the Prius but nearly all the plug in heaters available are 150W and the Prius and most modern cars seem to limit the power in the 12v socket with a 10A fuse, 150W = 12.5A = blown fuse. ?
Edit: just checked the manual and it seems we have a 15A fuse in the ZS front power socket, so a 150W heater should be ok.

An electric blanket for the legs might be another option
