CSS or Type 2

[hamd01]

Can someone advise regards buying a charging cable please?

Ive take delivery of the MG4 yesterday and I think Ive confused myself regards charging cables. It started when I began looking for a type 2 cable to have in the boot for when using un-tethered charge points.

Am I correct in thinking that to get a charge at faster the 7kw, you have to use a charge point with a thethered CCS cable?
So for example.....if you go to a public chargepoint that is rated at 22KW.... but it is NOT tethered, then there is no possible way for you to charge faster than 7kwph?
And that the only way to get 22KWph is to find a chargepoint with a tethered CCS cable?

From what I understand at a 7KWph charge it charges at around 23 miles per hour?

Ive seen some local chargers are rated at 22KWph, but have no cable...so as far as I unerstand there is no physical way I could charge the car at those units at anything faster than 7KWph, because the MG4 is only single phase?

Cheers guys....just wanted to ensure Im understanding it right.

No. 11kw needs a 3 phase cable. Best go for a 32a type2 3 phase as that will do both 7kw single and 11kw 3 phase. 11kw is only on the LR models so if you have an SR stay with single phase 32a

Most 11kw are untethered. Even at 22kw tethered or otherwise the max for the MG4 is 11kw on LR models and 7kw on SR

CCS is for DC charging and is always tethered

The miles per kwh is just an estimate. If you manage an efficiency of say 3 miles per kwh then 7kw = 21 miles range

You can't buy a CCS cable - they are always tethered on a rapid charge point.

So it's a Type 2/Type 2 charge lead you need for public AC charge points (22/11/7 kW), and a Granny charge lead if you visit someone/somewhere who doesn't have a wall box.



Edit: which model MG4? Only the LR models (SE LR and Trophy LR) support 3-phase charging, in which case a 32A 3-phase cable might be pertinent, otherwise a 32A single-phase cable is all you need.
Note: charging at home will only ever be single-phase maximum. (Apart from the rare locations which have 3-phase supply available).

Edit2: rating charge speed in MPH is a nonsense (IMHO) (I'm not having a go at you - I've seen it elsewhere, and it simply doesn't make any sense whatsoever).

If you have a SE SR the 7kw is the max you can get. If you have a SE LR or Trophy then it likely has a 3 phase charge socket and onboard charger, in that case you can get 11kw from AC charging.
Suggest if you can get 11kw then a 3 phase 32 amp lead us good as you get 11kw 3 phase and 7 kW single phase. Note 3 phase leads are a fraction heavier and slightly thicker/stiffer cable
Hint get one from Tesla by downloading their app and registering, in the app in the shop get the type 2 3 phase 32amp lead £85 is a bargain.

I originally thought that as you tend to think of mph as a speed.

What it means in that context is how many miles range per hour of charge.

So a 7kw charger on a car averaging 3 miles per kilowatt is a “charge speed” of 21 mph

Thanks for the tip. I've just ordered one and the app gives you access to their fast chargers that have been made available for non-Teslas.

The average EV newbie probably finds mph charge rate easier to understand than using kW.

I personally understand it but still find it confusing when it pops out of the page. Yes 7kw per hour will give you x range = x miles in an hour but I just find it peculiar to say mph because all I can think of is wheel turning speed. So my wired brain finds it difficult to separate "in" from "per"...strange old thing the human ?

Well, there you go - kW is already a charge rate (W=J/s, so it is kJ/s), so this confuses the heck out of many people with kWh giving total energy by adding the time component in.

I suppose it is all whatever you are used to.

Thank you guys for the help. So I think my conclusion is, if out and about....find a rapid tethered charger with CCS! I might get myself one of those Tesla cables as a backup.

Thanks again

Only if you want to save time not money as rapid charging can be more costly. If you have an LR use 11 or 22kwh fast stations where available...and you have time (and the cable). Also to add to the already confusing mix, rapid CCS charging done far too often is not the batteries best friend due to rapid charging creating more battery heat..oh the joys of learning all about the foibles of ev's

Good video on the subject by EVM…

Note UK Spec MG4 only have Single Phase 7 kW onboard chargers and in mainland Europe where 3 Phase Domestic supplies are more common then European Spec MG4 will have 11 kW 3 phase chargers.
So whether you use a 3-phase type 2 cable or not with a UK Spec MG4 then you'll still only get a maximum 7.2 kW charge even if you plug your car into a 22 kW Type 2 post. If you have access to an 11 kW charging post the 11 kW is across all 3 phases ie. 3.6 kW per phase 3.6 + 3.6 + 3.6 kW so you'll be charging slower on an 11 kW than a 7 kW.

It can be confusing when switching to EV but put simply if you have a UK spec MG4 then you'll only ever need a 32 amp Single Phase Type2 to Type 2 Cable. Anything else and you'll either restrict your charging speed or have an unnecessarily overly cumbersome cable

Of course, all the above is for AC Type 2 Charging. CCS, which stands for Combined Charging System, expends the Type 2 connector with two DC connectors for much higher i.e "Rapid" charging speeds and are only found on Public Rapid and Ultra Rapid Chargers (Tesla Superchargers too since the introduction of the Model 3). With CCS only the smaller charging control pins are used in the top Type 2 part of the plug while the charging takes place using the large DC connection in the lower part.

Barry this is not correct. Lots of people with UK spec LR cars are getting 11kW charging and this is what the UK manual states the car can do. It seems the initial information that was given out to dealers was wrong. SR is limited to 7kW.

Hi, what cable came with the car a type2 to type2 or 'granny' EVSE?.

Original batch came with Type 2 but I understand they're now being delivered with granny chargers.

 

[siteguru]

Mine came with a "granny".

I stand corrected. But this is unfortunate then for Trophy owners. Surely when you hook up your 64 kWh Trophy at home to a 7 kW single-phase wall box and you have got an 11 kW 3-phase charger only one of the phases is being fed with AC isn't it? Or have MG devised a plan to couple two of the 3.6 kW 3-phase charging circuits for a combined 7.2 kW?

 

[siteguru]

Technically the single-phase rating is 7.36kW (230V x 32A)

Having the capability of 3-phase charging (when available) is the important point - the fact that only a tiny percentage of people in the UK will be able to 3-phase charge at home is irrelevant.

 

[Deleted member 9909]

That's why you need a 32a 3 phase cable which means a single phase can still supply 7kw...and the onboard charger accepts that on a single phase. The charger/cable/inbuilt charger signalling determines charge rate and adjusts accepted input accordingly.


The standard charger has an input of either 7.3 kW if it uses only one phase or 11/22 kW if it uses three phases. The charger is also able to detect whether it will be able to use only one phase or three.
