Does Intelligent Speed Limiter (TSR) disable regeneration

[Italy]

It's logical that a combustion engine should use very little fuel to recharge a lithium battery, as it doesn't have to drive the wheels and can't support the weight of more than 1,000 kg.

Look at a thermal electricity generator that some people have when there's a power cut. Electricity consumption is relatively low.

Are you sure about that, I've not read it elsewhere.

Advanced, smart features of Hybrid+ include a drive and charge system that allows the petrol engine to drive the wheels whilst also charging the battery through the generator.

Regarding the starting of the internal combustion engine, which may seem anarchic and uncoordinated, it seems to me that MG's priority is to recharge the 1.83 HT battery and be able to drive electric.
Unlike Toyota and Honda, who do not favour electric operation.
The internal combustion engine that runs to recharge the HT battery in the MG3 must not consume much because it does not drive the traction wheels.

Hi all!

About favouring electric operation, my 2022 Honda Jazz eHev seems quite similar to the MG3.
The thermic motor, turning at its most efficient speed, is only here to regenerate the electrical battery, except above around 90km/h where it is directly connected to the wheels (because above this speed is the range where the thermic is the most efficient).
And if all the thermic power is not used to move the wheels, it will parallelly charge the battery till around 85 percent.

My 2 cents...

I found this information and from my recent long trip I can confrim that this is what it does:

The car runs in a variety of ways’ EV is only for short distances, depending on how much charge is in the larger-than-average 1.83kWh battery pack. Beyond that, there’s ‘Series’ mode, where the engine powers the electric motor for drive, ‘Series and Charge’, where the engine also tops-up the battery, ‘Drive and Charge, where the engine drives the wheels and charges the battery, and ‘Parallel’, where both engine and electric motor power the wheels.

Sport drive mode firms up the steering and has it running in Parallel mode more readily.

In addition, I aslso found that if you start the car remotely using the iSmart app it uses the engine only to heat up the car - very efficiently as well.

Hopefully a scrote doesn't nick it while it's running.

It remains locked, that's the idea ? Try it, but you can only bind it to one phone at a time. The same app will scan the status of the car and tell you how many miles you can do, which is handy and also a map showing the location of the car, in case someone does nick it

I've tried, the dealer has tried a kid has tried and so far no one has managed to set up the app yet.

.... allows.....but not always, the nuance is subtle.

Yes, I agree, because I've also owned the Jazz, but .... the MG3's HT battery is much more powerful than the Honda's, and the MG3's internal combustion engine recharges the HT battery much sooner than the JAzz, so you can drive electric.

The amount of power the motor uses CANNOT be replaced by the engine so it has to drive the wheels also it has a 3 speed automatic to that end.

You need to give all "consents":
on the app and on the machine.

Also try force disabled on the car in case someone has already linked it

I got an answer eventually from MG customer support who said:

I can confirm based on your question, "when the ISA is engaged it disables the brake regeneration", it shouldn’t function this way.

It will control speed; the car will accelerate and brake automatically when using adaptive system.

If the car is braking, it will be putting energy back into the motor.

So, it should not be disengaging - the second two paragraphs are just a copy and paste load of rubbish that has nothing to do with my query, but hey, ho. I have asked them to confrim that it needs to go into a dealer to be repaired - but I still think it is a software problem that they have overlooked and very much doubt if the dealer can sort it, but I'll try to keep my glass half full!

I also noticed on my MG3 that when brake regeneration has been disabled by the ISA that the drivers display still shows the level of regen you last had selected before it was disabled.

I got a further reply from MG customer support, this time within a few hours as follows:
We can only recommend that if you are experiencing an issue with the vehicle, I would recommend taking it to your local MG dealership for investigation.

It will be interesting to know see what the dealer says

Thanks @ptw

I have a final solution. When I contacted MG customer services the second time, they came back to me and asked me for my registration number, then suggested I contact the dealer. Before taking it to the dealer I decided to double check that the regeneration was disengaging when using the ISA and surprise, surprise it was working correctly. I am convinced that they made adjustments over the air, which I know they can do for updates, which is why they asked for my reg number. There's no other logical explanation.

Thanks @ptw

Can you read my last post. Perhaps if you email customer services with your reg, yours might start to work properly, it would confirm what I suspect

Email sent, thanks very much, I'll let you know what happens.

 

[ptw]

I don't rate it as a motorway car at all. The engine is too harsh and the road noise is terrible.

Well, I did my long trip and I didn't find it harsh or noisy at all. It does scream a bit when you floor it, but it does take off like a rocket and I think most cars make a lot of similar noises when your foot is to the floor. However, no road noise that you mention, perhaps you have different tyres? I think that on normal roads and lower speeds than motorways the whole car is exceptionally quiet, which I'm very pleased as I was hoping I wouldn't experience the things you mentioned

 

[gian]

For me too there are no problems on the highway,
the engine noise is more than acceptable,
except when it roars for fast overtaking,
the noise of the rolling of the tires is the same for both the original tires and the winter ones and is normal.
consumption is also good, traveling within the permitted limits (max 130 / 140), beyond that I don't know.
For a segment B car, with the price it has, you can't expect more.

Correction, I made an operator error, although I double checked the ISA was set, I didn't activate it on the steering wheel, so of course the regeneration still worked, but as soon as I activated it the regeneration disengages. So, I will book it into the dealer for them to look into it. Sorry for making such a dumb mistake.

Don't worry about it mate, I'm still waiting for a reply from them.
