5.5 miles/kWh!

[dragon2611]

Trip computer was showing 13.8Miles per KWh at the weekend, but then I guess a 7.6Mile trip where it's pretty much either flat or downhill will do that...

Pretty sure it was much more abysmal on the way there...

I'm convinced my MG4 average is just distance over time, so it takes into account all the stops as well. It's not averaging all the speeds while moving. So for our purposes it's useless.

As its an ev stops are not relevant as the car uses no power, motor goes to 0 output as soon as the car is stopped regardless of whether the system is switched on .
Look at your power usage graphics and you will see no output from the motor. Ice cars of course need engines on idling speed to function so use power all the time and that does affect consumption

The motor may not be turning but that doesn’t mean the car is using no power, a lot less but it still needs to keep all other systems going.

@decrep is talking about average speed which is where stops are relevant in any type vehicle.

12V system certainly, average speed does not relate to battery usage as I said previously .

An EV in standstill is using the HV battery to power all systems, which can be a significant load (think freezing winter night)…

 

[Photogreycat]

In winter I get 3.5 miles per kWh. A rapid charger at a motorway service charged 80p per kWh.

Hence the cost per mile is 22p whereas a petrol car cost per mile is 14p

It seems to demonstrate that ev’s are not viable if you can’t charge the car at home.

It's easy to check by looking at the electrical display on the dash.
In the summer mine was showing 1A while stopped but no air con running which is around 350W.

I can’t charge at home . I charge at work and at Tesla chargers. Between 30 and 40p per kWh. I average 3.7 miles per kWh during the year (10k miles).
10p per mile.
Let’s though imagine I do 4k of those miles using public chargers at 75p per kWh
6k miles at 35p = £568
4k at 75p = £810
£1378 total
14p per mile.

 

[maskull]

I can't charge at home either and I can't really say that my EV is more expensive to run than my last 2 hybrids ( both returned 70mpg ish ). My 5 has returned 5mi/kWh the last three months and was hovering around 4mi/kWh in the winter, add to that no VED ....for now
I mostly charge at a local Connected Kerb for 45p/kWh with my Bonnet Boost, rarely use DC chargers though my nearest ones are 67p/kWh with aforementioned Boost.

I don't know what petrol car you are comparing with but I doubt that you'd get 14p per mile if you filled up at motorway service stations.

My diesel Merc did 50mpg which works out around 15p per mile. Driving the same way my MG5 is doing 3.9 miles per kWh (summer) so when charging at home at 30p per kWh its 7.7p per mile. Where I live the cheapest EV tariff is 15p so when using that I'll get around 4p per mile.
Hopefully that will give an average over the year between 4p and 6p per mile.

 

[Gomev]

My last ICE vehicle achieved 50mpg but only on a run, however only 30mpg pootling around town for the majority of the time. It wasn't a hybrid.
So my question is....everyone quoting 50 and 70 mpg for their cars, are these average or the best achievable figures ?

 

[mj224]

I think when quoting miles or km per kWh, you should also indicate outside temperature.

Temperature makes such a difference to the figures.....

Mine is based on two hybrids ( Hyundai Ioniq ) each owned for 3 years and 50,000 miles . The figures came from the cumulative trip

 

[Photogreycat]

I don't know what petrol car you are comparing with but I doubt that you'd get 14p per mile if you filled up at motorway service stations.

My calculations are based on a petrol fuelled car at 46 miles to the gallon and petrol at £1.45 per litre. The car was a Hyundai i10.

M25 SOUTH MIMMS SF CONNECT MOTORWAY SERVICE AREA

• UNLEADED. 169.9p. by Site Owner Update Price.

It was more of a comment on Motorway service station prices than the car.

But more seriously the price of rapid charging in the UK seems ridiculous. On a recent trip to The Netherlands I was paying about €0.30 at peak times at Tesla superchargers.

My diesel Merc C Class averaged 50mpg over the last 10k miles.
This is a mix of motorway, country and town driving but not much commuting.
If I were commuting every day and driving in town more this would drop to nearer 40mpg

I only get 3.1mile per kWh in my new MG5. I've done over 500miles in mild weather. I'm Starting to think something is off as that seems very low.
Driving type city 30/40 and one motorway of 200 miles at 70.
Mode: comfort
Regeneration mid.

Not sure what mild weather means but if it below 12C you’ll see higher consumption from PTC heater for cabin and possibly battery too if below 10C and you have battery heating enabled or below 0C and the battery is stone cold. Plus brand new tyres will possibly have a bit more rolling resistance in the first 2/300 miles.
This is assuming you are a seasoned EV driver and don’t have lead feet

 

[Verdigris]

Eco mode is good for training an ICE foot. Eventually you'll develop enough sensitivity to get decent consumption in Sport mode. And avoid stopping completely - creep is your friend in that respect.

Also, 60mph on motorways will save many electrons.
