MG HS PHEV
Hi,

I have bought MG HS PHEV 15 days ago. I do not understand the driving mode and I do not agree with what a sales person has told me. I found this forum via google and there are some really intelligent answers so I thought this would be the good place to start.

1) as per manual, MG HS is in hybrid mode it drives in both Engine and EV together. Dose it mean battery is giving power to the car but not actually saving any petrol? Like other Hybrid cars it runs on hybrid battery when there is a juice in the a battery.

2) Different mode of battery,

auto , medium and high.

which is the better way to keep the car when you are on the long drive. I have done 400 km and my average consumption was 7.2liter/100km. My car mostly driven on the motorway with average speed of 95kmph and trip average speed was around 70kmph... As per my understanding hybrid should have around 5.0 liter / 100 km due to battery take over wherever possible.

So can someone please explain what is the best mode to drive to reduce the petrol consumption to the hybrid level or it is normal what I am seeing.

This is my first hybrid car so I am not that much use to with it but my friends drive RAV4 hybrid and their average is pretty good.


Thank you,
 
Hi
you car will make up its mind what is the best mode to be in. It will save you petrol, if you travel short distance each day to and from work use the it in EV mode. It will run in this mode if the temperature in the car is set lower than the outside temperatur. I am not sure of your weather but here in winter on cold days with frost on the window I need to have the temperature set in car at 23 then when you start the ICE will start and then I have heat in the car, after a few miles and can switch over to EV mode, now spring is here and the days are getting warmer I am getting back to just using EV mode all the time.

As to the battery auto medium high just leave this on auto, the car will always set its self to this. When I got my car I did a. 100 mile journey, the fist 34 was in EV mode until the battery was empty then the ICE started and selected the high setting over the rest of the journey which was fast road it but back in 80% of battery power ( this the max from the ICE you can do ) but the MPG was down to 25. I have just done the same this weekend but let the car do its own thing and was up at 37 MPG.

In. Normal week I do 16 miles a day to and from work, I charge the car every night which take about 2 hours using the granny charger and cost me a £1 and I may put in petrol about once a month to top back up around £10. I would normally use aound £25 a week in my old car which I now save and in the time I have had the car I have saved over £500.

hope this helps.
 
My experience reflects what Jto has written. After 7000 miles, with about 60% of them being local EV motoring and the others being fast runs on motorways in standard Auto mode, my overall mpg is 69.3 (4.42L / 100K).

To fully charge the HS PHEV battery from a very low SOC to MAX in 2 hours, you must be using a 7kw wall box surely ??.
Unless you have some remaining range left from the previous day of course, and just topping up 🤣.
Charging from empty to full is more like seven hours on the “Granny” cable ???.
Please correct me if I am wrong here 👍.

From flat to full is around 6/7 hours hours on a granny charger. A wall box would probably do it in 4. The issue is that the car only takes a maximum of 3.6kw per hour regardless of the input, so this is as fast as it will charge.

Although it has a 16kw battery, you can only access about 14kw of it to stop it being ran flat so the best your going to get is 14kw / 3.6kw = 3.9 hours.

If someone gets a full charge in 2 hours from a wall charger, they must have 50% battery (7kw) left in the car.

I looked into wall chargers, but the saving of a full charge taking 4 hours and not 7 hours was pretty pointless. At the end of the day if the battery is flat, I have a perfectly good 1.5 turbo petrol engine to get me round until I can charge it up again.

I have looking at a previous thread on the charging speed of the HS PHEV.
Owners have contacted MG direct and have been told that the new HS PHEV will change at 7kw’s on the correctly rated A/C post ?.
I find it really strange that this issue of the max charging speed is unclear ???.
Why do MG customer services in responce to queries from customers, still insist that the car will charge at 7kw’s ????.
Have more recent cars been upgraded or something ?.
Is it 7kw’s or 3.6kw’s is the $99 question.
6 to 7 hours on a Granny, would then imply about 4 hours at 3.6 kw’s and 2 hours on a 7 kw wall box then ?????.
Can somebody who has recently taken delivery, kindly please comment on the charging speed please.
Thanks !.
 
I've recently taken delivery ( placed order in Nov 21, rec Apr 22 ) - yesterday at 0% on a granny charge it took 6hrs 9 mins.

Granny charger will be the same across old or new PHEV. Granny charger max out at about 2.3kW. Really need to test it on a 7kW wall/public charger.

If I do 16 miles to and from work that is 61% left so only takes 2 hours to bring back to 100% 32 miles.

I think this points out from MG web site 100% in 4.5 hours on a 7kw @ 3.6 kw that is the on board charger.

I can understand why people become confused by the way MG write up these figures.
Why state, when charging from a 7 kw supply, the car will charge in 4.5 hours.
When actually connecting to a 7 kw unit it will still only pull the same as if was connecting to a lower powered 3.6 kw unit, due to the on board charger in the car that can only handle 3.6 kw's ???.
Not everybody will have a 7 kw unit installed, some PHEV owners go for the 3.6 kw unit ???.
My VW PHEV would only charge at 3.6 kw's regardless what size wall box you where connected to.
When I had my wall box installed to charge the VW back in 2015 - I opted for the 7.0 kw 32 Amp unit, knowing it would only achieve 3.6 kw's via the on board charger in the car of course.
However, I did give some thought to the fact, that some day I may want to go full BEV.
Well, I am now on my 2nd full BEV after owning the PHEV in 2015 and therefore this was a great decision back then !.
The battery in a PHEV is by its very nature is fairly small.
When you compare it to the much bigger battery in a BEV.
Maybe the designers consider that charging the smaller battery with either the MAX 3.6 kw's or even slower with the "Granny" cable, is a just a little kinder on that small HV battery over the long term life of the car ?.

Yes if I knew what I know now I would have gone full EV.

I owned a PHEV for over four years and loved every day driving it !.
I had no complaints about the car or the way it performed.
The link between the EV and the ICE was almost impossible to detect.
The six speed DSG box was slick and smooth as a silk shirt.
2015 was my first introduction into the big world of electric propulsion and I feel in love with it straight away !.
I was bittern hard by the EV bug from day one almost.
Using the EV mode as much as possible, in order to maximise the fuel savings.
That was in 2015 and energy has become much much more expensive now !.
Plus - I always found myself wanted to be EV mode all of the time, due to the smooth and silent ride.
It sometimes came as a shock when the ICE suddenly jumped into life.
Where did that noise come from ????.
I personally feel that a PHEV is what I call, a brilliant "Bridge Car" into the world of a full electric car.
There will still be a usage case for a PHEV for a few more years yet to come.
But I did find, that after the first few years of ownership, that the service costs of the PHEV started to become more and more expensive each time it was offered up for service.
I think we have to remember that with a PHEV you trying to serve TWO masters here.
You have the service requirements of the ICE unit, plus any service considerations of the EV side of things to consider also.
Would I go back to a ICE car now ? - NO !.
Would I return to a PHEV if necessary - YES.
Would I choose another PHEV over a BEV - NO.
As EV battery size and technology increases and improves, together with more charging facilities.
I think PHEV's will slowly become less of a thing.
In the recent re-banding of the road fund licence in the budget, PHEV's are now being rated at the same coast as a oil burner ??.
That can not be right surely !.
In 2015 my PHEV was completely free, the MG HS - PHEV is now a ridiculous £165 I think.
Stupid unfair system.
 
Okay here you go.. just over 11k miles in just under 11 months. Every day usage is electric except when needing to go out of electric range..

  • EV Mode: Start the car, check if EV is on and if not switch it on.. that's electric only. Perfect for local usage with range close to 40 mile as urban speeds
  • Auto Mode: If EV mode is not enabled, the car uses hybrid mechanism. EV up to 24 mph and then ICE switches on. The car uses both battery and engine at higher speeds.

Battery mode: Default, medium & high dictate how the car treats the battery.
  • Default: The battery is used as above
  • Medium: Battery is used as above but car tries to keep state of charge at 50%. It will continue using hybrid mode but often rev higher to push more amps to battery to maintain the state.
  • High: Same as above but battery state of 80%.

The battery modes are great for when you are towing but otherwise not worth the hassle. At motorway speeds - 70mph, the car will keep adding a few amps here and there. This monday I was driving back with family from Cardiff > Swansea and back to Cheshunt. Started with empty battery and was 12% when I got off motorway close to home.. 12% was enough to drive in electric to home and go to the shops to get some dinner.

The best way to see what is in operation is to look at one of the screens in the same list that has trtip meters.. It shows amps, volts, motor speed and engine speed.

Good luck..i wont have that issue..with a 1.5 turbo petrol engine
EV a waste..£12 grand for a new set of batteries.
And no one knows where to dump the old ones..ha ha...France has fields of them..dont know what to do....not very well thought out..yet people couldnt wait to buy one..to show their neighbours and mates.
Ooh..look at me..its electric you know..no engine..only battery..i'm helping to save the planet you know.
🤣🤣🤣🤣

Seriously why do you come to troll when you have no insight into how HV Batteries work.
  • No one ever dumps HV batteries.. The metal inside is 100% recycled. Recycling any metal is far more efficient than processing and extracting it from Ore. Ore tends to have little material that requires substantial processing to extract it.
  • HV batteries are recycled by the manufacturers themselves because it makes financial sense. Often these manufacturers start their own BESS systems and these batteries even when degraded beyond use in automotive applications can take BESS loads without any issues.

Please go back to doing whatever you were doing.
 
Well i never..and they say you learn something new every day.
I certainly have..being old makes me think ideas are old fashioned ones..and batteries are the same as they always were..or maybe too much false info that i copied.
My apologies old chap..
