I'll be shocked if that's correct for either of the launch models in the UK. But fingers crossed.This page seems to this it has 1500kg towing.
MG4 inducts Range & Performance variants; interior upgrade to follow in 2024
The MG4 EV inducted an extended-range variant and a high-performance variant in the Summer of 2023. Next, it will receive some interior changes.
That's quite an ask. Assuming 4 miles/kWh that's 25kWh in 20 minutes, so an average rate of 75kW which would need at least a 90kW charger. For the smaller battery that's 20-70% and the larger battery 20-60% so before you'd expect significant throttling.
Is ir? The Ioniq 5 or EV6 with a 77 kWh battery can add 100 km (60 miles) in less than 5 mins, or go from 0-80% (adding over 61 kWh) in less than 20 mins. The MG4 LR charge rate is quoted as up to 125 kW. We can expect some gradual tapering of charge speed beyond around 80% SoC but on a charger rated at more than 75 kW that is the sort of speed we should expect isn't it?
mg5 lr using the battery heater got 92kW from 10% to 35% then 78kw to 45% then it dropped to about 68kw till at least 60% and I stopped recording. I do know it can still pull >50kw up to 80%.
The Ionic and KIA achieve those speeds on 800v chargers - there's no mention of that technology with the MG4.
@Les burrows , on your phone get AmiGO app, it is Tomtom, is free and is pretty good, I've been trying it out recently.
Yes you are right, the Ioniq 5 and EV6 are able to charge at 800V and hence a direct comparison is unfair. There are multiple technical problems at charging at these high rates, not least managing the heat generated, so it should be possible for other manufacturers to achieve around half their speed at 400V assuming that the charger itself is not the limiting factor.
So what is a fair expectation for a car marketed as being able to charge at a peak rate of 125 kW when the charger is not the limiting factor?
I find this kind of info interesting but am mostly happy that it will charge faster and go further than my MK1 ZS
In general I agree with you right up to the point where you are significantly inconvenienced. Case in point; I made a 250 mile journey to attend a funeral in January 2001 and found that my Mk1 ZS was charging at around 30kW even after driving fairly fast for 120 miles and arriving at around 10% SoC, and hence taking more than an hour to go from 10-80% and add another 100 miles range. I still had to make a second charging stop adding a further 15kW in around half an hour and only just arrived in time for the service.I find this kind of info interesting but am mostly happy that it will charge faster and go further than my MK1 ZS
Based on my experience charging the mg5 lr and the spec of the mg4 I would say 160 miles of real world range added in half an hour if you charge from 10%. This is a guess Based on me charging the mg5 lr and the difference in specification it has to the mg4 hopefully without any mistakes.
The problem with the mk1 zs and the mg5 standard range is there is no way to preheat the battery. The mg5 lr has a battery heater that you can turn on that significantly improved the rapid charge speed.
As far as I know, all chargers in the UK are load balanced, and to expect the same charge rate, wherever you charge is unrealistic. The manufacturer cannot and will not supply you with information on what to expect, as again, that all depends on the amount of people charging around you, at any given time. I have very rarely achieved the advertised charge rate, and that’s purely as I was the only one charging, and that is diminishing by the day, as more EV’s are sold.
Interesting. A battery heating option was offered for the Mk1 ZS for a while but it was found that in the UK the improvement in charge speed did not justify the energy needed to pre-heat the battery. Do we know if the MG4 has a battery heater and what the impact of that might be? Does the active grill make any difference to battery temperature and hence charge speed?
From memory the mk1 zs update was made for sub zero climates where it was not managing to rapid charge properly as the heat generated when charging wasn't enough to warm the battery enough to allow higher speeds. I believe it only heated the battery when temperature was lower than -10 as they found when it was cold in norway the charge speed was ridiculously low and the waste heat was not enough to allow faster charging as the battery warmed. The battery heater on the mg5 lr heats the battery to something like 20°C when you turn it on and keeps the battery warm ready to achieve high charge rates when you get to a rapid.
I get that in the real world there are variations, but the likes of Fastned are able to produce charge profile graphs and WLTP figures are published so clearly it is possible to standardise metrics.
