Public charging query

[Mrs B]

Hello
I am relatively new to having an EV and I'm probably being very thick but is it possible for me to get my car to charge on a 22kW public charger if I am only using my own cable? My cable is type 2 to type 2. Last time I used a public 22kW charger it only charged at 7kW? Is it because I need a different cable or can you only get a faster charge when you use a CCS tethered type of charger please? I'm not overly techie so you'll have to explain it to me in simple terms, apologies!

You can charge it with your own type 2 to type 2 on a 22kW public chargepoint. The most speed you will get is 7kW though. That's all the car can accept on type 2 on UK models.

Thank you. So it accepts higher charging speeds but only when using the tethered CCS type of charger?

For AC you will never get higher than 7kW. (see picture for AC), irrespective of whether it's tethered or not.

For DC (see picture for DC) it can be higher. You will always have a tethered cable for this.

Note that's for UK MGs. Other cars from other brands may get 22kW from AC chargers. But not the current MGs sold in the UK.

Its nothing to do with the cable. It's what's in the machinery of the car that determines this.

Thank you so much, that all makes sense to me! I now know I will only get a couple of hours charge tomorrow night when I come up to see my son at university near Heathrow. The chargers say they are 22kW (I looked on Zapmap) and I need to supply my own cable. A couple of hours should be enough, it's a 98 miles each way journey for me and in summer I can do it there and back with no charging. I'm just playing it safe as clocks have changed and lights etc will be on for most of both journeys so a two hour charge at 7kW will most likely be needed!

I'd just plan an optional stop somewhere for a DC rapid charge, rather than be tied to a slower AC charger in this case.

I've got two hours to kill while I'm sat in a concert, so it will get easily two hours and a bit more charging. Might as well make use of the time while I'm sat there.

You should be able to put 45 to 50 miles in the tank.

You need a 22kw lead.

 

[DB Go Rex]

You need a 22kw lead.

Not typically cable restricted.

Any decent type 2 lead will get 22kw if your car has a 22kw onboard charger.

But none of the UK MG ZS EVs do - the onboard charger is 7kw so the most you will ever get is just under 7kw after charging losses.

So it’s not worth getting one of the dearer cables from my link then? For faster charging I mean.
I’ve just bought a ZS sr and need a type 2 cable

The MG ZSZ EV only has a single phase 6.8 kW charger fitted in the car. Even if a type 2 charger is rated at 22kW the ZS will never get this charge level no mater which cable you use. The only way to charge at higher levels you will need to use a DC rapid charger which will always have a tethered cable with 2 extra sockets below the type2 socket.

Simple answer is no. You'll only ever get 6.8kw.

That listing is bonkers.

The more expensive "11kw" labelled cable is listed at 16amp whereas the cheaper "7kw" is labelled 32amp.

Snake oil! We've reached gold plated HDMI audiophile territory now...

 

[Rutsy]

You just need a cable that is rated 7.2kw, 32 Amp.
