3 phase charging.

3 phase charging
Hi,
I posted this on the Reddit sub and they suggested that I try here:

I installed a 3 phase charger that charges up to 22Kw. 32A on each of the 3 phases @ 240v per phase.
I am told that the max for the MachE is 11Kw.
So, 16A on each phase. The car is taking 16A on phase L1 and 16A on phase L2 but nothing on phase L3. It is reading full 240V on each phase. The charger company were excellent in sending me another charger straight away but it is doing the same thing. Any ideas?
I am thinking a faulty charging port. Or maybe the charger in the car? The 6 connections on the port are L1 L2 L3 N, just as in a 3 phase plug, and 2 communication ports I presume. Does the 3 phase charger just deliver mains voltage to a charger in the car? The car takes the full 32A available from my single phase charger, it would probably would take more if it got it but will only take 16 from each phase on the 3 phase charger so I think it is recognising the 3 phase charger and limiting the current to 16A on all phases.

Hello and welcome to the forum!

The first thing I'd figure out, is if it's your car or your charger.

You can try charging your car from another 22KW (level 2) charger: see if you can find a public charger near you, and see how much it draws. And, if you have a friend or a neighbour with an EV, have them try your charger and see what they get.

You're right in that the Mach-E is limited to 32A single-phase over type 2 connector, and 3x 16A three-phase. And yes, the charger (technically called an EVSE) is essentially a pass-through line that connects your car to the electricity grid; it doesn't do any conversion or such.

Who installed your charger (and what brand)? You might need to call them back. From what I can tell, there are a few different ways of wiring a 3-phase charger, depending on where you are in the world, and what your electricity supply is.

You are claiming you are certain the mache has the car side of 3x 16a , with type 2 hardware? It certainly makes sense, but i think that's what op was asking....

Any update to this? I have the same issue... My Mach-E (2022 Premium extended range AWD) charges only 2phases at home charger but public chargers works normally at 3phases 11kW.

Only L1 and N carry current. I phase Ether 240 or 120. (ok I understand that the N is actually 180 out of phase with L1 to get 240 but that is the way it is.) My power supply understanding is 3 phase would require a entirely different design plug and front end to the rectifier in the car. Adding design complexity and production issues for something not very common in household use.

Well in Finland its very common to have at least one so called "Power" socket in the household. We have 230V system and this power socket means that it has 3-phases: L1, L2 and L3 all of them behind 16A fuses. Mach-E should be able to charge from all of them approx 3,7kW / phase if you have home charger that is capable to do so. Charger that I use is this one: https://www.chargeamps.com/product/charge-amps-luna/

None of that applies since these folks are in Europe!

It can charge at 3x16A on 400V system. It is important to note the current is limited to 16A when not in single phase mode, so it can either charge on 3x16A, 2x16A or 1x32A. On 230V systems without neutral it is limited to around 7kW since it is virtually using only two phases and the third is used as neutral.

On 400V it can reach the max rate of 11kW. In all other cases it is (for EU version) limited to about 7kW.

@Teslaeata - do you use a 3 phase EVSE in the UK?
