Hi, just bout new mx-30. Recently when I connected type 2 cable charging almost immediately stopped and charging point turned off as if it was short circuit. I tried several charging station and didn't manage to charge car on any of them. No problem with rapid charge with ccs1 cable. I think it can be pin problem or smth. Does anyone experience kind of a problem? Thanks.

Sounds like you need to try another type 2 cable...if you can source one...to rule that out and point the problem towards the car's inbuilt ac/dc convertor. It could just be a cp or pp signalling issue but until you try another cable 馃

I also assume you haven't got the AC manual % charge limit settings too low and no active schedules.

Tried different cable, still same issue. Resistance on pins is very low, though diagnostics doesn't show any errors. If it was an iron I would definitely think there is short circuit somewhere.

So to summarise

No schedules
No low AC % in settings
Different chargers
Different cable
Car pins look clear with no debris and no dirt

So it points to a car issue

I tried different charging station, I tried home socket too.l with different cables. Weird this is that diagnostics doesn't show any type of error.

DC charging works using same cp, pp and pe terminals. Does not use l1, l2 or l3 but uses dc +ve and -ve. So no signalling issue on terminals if dc works OK.

Please confirm there are no schedules set and that ac charge level is 100% in ev settings. If charge when connected shows a schedule is in place. If all this is correct it points to either L1, L2 L3 input terminals issues, depending on how many phases your chargers use, or the ac/dc convertor in the car. Either way it sounds like a dealer visit.

I guess diagnostics should show some errors if the issue was ac/DC converter. And if the issue is converter then it should charge with DC, right? I really hope it's just on car pin issue.

It may not show in diagnostic logs as no error message maybe being sent in the first place depending on the nature of the fault. All checks made that I can think of. Next stop ac/dc convertor check.....and yes if dc charging is OK then all fingers point to l1 - 3 or convertor

I'm sorry for being noob, but what is L1, L2, L3? Is it the pins on the input?

On a type 2 cable for 7kw charging you need L1 for single phase live input. L2 and L3 come into play for multiphase power input. Neutral is also used. Given you said DC (fast charging) works ok that uses the same cp,pp and pe pins as 7kw charging but ignores L1,2,3 and n and uses the +ve and -ve pins at the bottom of the fast charge cable. See the link I attached previously. Top picture is type 2 ac and bottom picture is type 2 DC.
