MGZSEV Exclusive 70 plate 8000 mls only charging to 157 miles despite the weather not being cold

[Coulomb]

After my wife had driven & charged she would always get several more miles range than me so that must have been a variable factor in the range calculation which is probably the same on the MG.

Except that with the MG, you have the option of wiping that effect by resetting both trip counters. OP does this always, so history should have no effect.

With respect to "only 8 000 miles", battery degradation is primarily on temperature, voltage, and time (age). In a sense, "You may as well use it, since you're gonna lose it anyway".

It’s a GOM, it isn’t that accurate, particularly in the MG. You can’t work out battery degradation from it as there are so many factors that influence the read out. We have a 3 year old i3 that is still achieving the same amount of range as when it was new.

It suggests to me that your overall m/kWh is less than 3.7.
Do you do a lot of short journeys ?
Take it on a longer trip on A-roads 50-60mph tops and your m/kWh will go over 4 and bring the range back up.

My thinking too. On my Trophy after long (70m min) roundtrip journeys on country roads an Eco mode a full battery charge has more than once offered 295m as range. The trip recordings have been 4.1-4.4 m/Kwh

You're paying 48p per day standing charge with Octopus? Bugger, we're arranging to get solar panels done and I was going to switch to them but that standing charge is almost double my British Gas charge of 25.92 per day.

We got put on Octopus energy when Avro energy went belly up and our standing charge for electricity is 41.98/day. Scandalous. We only do short journeys & 157 miles on a full charge & that's all I see on the GOM after resetting everything.

Original ZS EV I assume @chowbenter ??.

Hi and sorry if the following has been discussed but, our MGZSEV on a 70 plate with 8000 miles on the clock is now only achieving a charge of 157 miles despite the current moderate temperature (climate). The car is charged on a home charger and periodically charged on a Granny charger to balance the battery is 157 miles in good conditions and good battery management a sign of something amiss ? (PS Our MG has been serviced by an authired MG dealer).

Strange my one is the same got it with 800 miles on the clock it has never charged to the 168 that they say it should.

Mine has done same thing - 70 plate, 9000 miles and now won’t go over 157miles on GOM after an equalisation charge. Will try an unlock and re-lock of the car sometime next week and see what happens.

Thats only a 3% difference which I wouldn't bother about. Batteries are not mechanical things that can be predicted exactly. If you change the driving mode it will give you a much larger range difference than 3%. We had a Mitubishi Outlander PHEV that used to show how efficiently you had driven. After my wife had driven & charged she would always get several more miles range than me so that must have been a variable factor in the range calculation which is probably the same on the MG.

Yeah original MG ZS with the original 455v software.

Is that with hvac switched off, drive mode un Eco ?
In the more mild weather we are having my vers. 1 ZS EV charges up to 330 kms which is just over 200 mls. (HVAC off, in Eco)

 

[Tom Hartley]

Thank you all for your responses / contributions. (Ive been on holiday).
It's reassuring to know the MGs battery degradation is a measurable and know phenomenon.

Why is it scandalous?

 

[Kithmo]

Why is it scandalous?

Probably because of the obscene profits the energy companies are making now they've almost doubled the standing charge.

Exactly my sentiments too, We're being gouged something rotten with these ridiculous price rises.

On a good day I get 159miles using a granny charger and Driving Mode in Eco, if that helps. (20 plate, 13 months old).

My understanding is that the vast majority of companies supplying gas and electricity to UK households and commercial properties are not making much, if any profits at all. That's why so many have gone out of business over the last year or so. Some might be making profits now, but will be looking to recover the significant losses made in the last year or so. Many firms were selling to customers at prices lower than they were able to buy energy on the wholesale market meaning every customer was costing the company money. The wholesale cost per unit of both gas and electricity has quickly sky rocketed to prices nobody in the industry could have anticipated. The war in Ukraine has not helped.

The oil and gas sector is a different story....that is where the big profits are.

Surely if it was battery degradation then when ‘fully charged’ it wouldn’t show the same amount of volts as when the battery was 100%. Pre and post mileage loss I was getting 449v (latest updates installed) after a full charge with equalisation. If it was battery degradation then the volts would now be lower?

Voltage with a load on would tell.

 

[Coulomb]

I don't believe that's how it works. A battery if double the capacity doesn't necessarily have double, or necessarily any more voltage, just more active volume to store ions. The battery voltage is about the balance of ions, not the number or volume of them.

But I'm no battery expert.

 

[Coulomb]

Voltage with a load on would tell.

A degraded battery will typically have a higher internal resistance, which can be noticed as lower voltage under load, yes, but I don't think it will be noticeable while the state of health is in the 90-100% range. At age 5-10 years perhaps.
