Question Is 120Ah 2019 Euro-spec car supposed to have 3 phase AC charging

Hi,

I've been working on support in OVMS for the I3. I'm using OBD-2 queries.

As a result I have a question: is the I3 supposed to do 3-phase AC charging in the Euro-spec model?

You can get a voltage measurement for 3 phases via OBD-2.

When I connect at home (single phase) I see this:

Code:
2020-12-28 13:23:38 SAST I (4238185) ovms-server-v3: Tx metric ovms/steve-demo/CAA5060/metric/xi3/v/c/voltage/phase1=219
...
2020-12-28 13:23:38 SAST I (4238175) ovms-server-v3: Tx metric ovms/steve-demo/CAA5060/metric/xi3/v/c/current/phase1=5.9
So that's seems sensible - the car reports voltage on phase1 only, and pulls current from that phase.

But I took a drive to a AC charger that I believe is 3 phase. When I connect there I see:

Code:
2021-01-09 13:24:39 SAST I (441221) ovms-server-v3: Tx metric ovms/steve-demo/CAA5060/metric/xi3/v/c/voltage/phase1=230
2021-01-09 13:24:39 SAST I (441221) ovms-server-v3: Tx metric ovms/steve-demo/CAA5060/metric/xi3/v/c/voltage/phase3=233
...
2021-01-09 13:24:39 SAST I (441221) ovms-server-v3: Tx metric ovms/steve-demo/CAA5060/metric/xi3/v/c/current/phase1=15.9
IE, my car reports voltage on phases 1 and 3 only, but it reports 0v on phase2.

It only actually reports current from phase1 and so its a single-phase charge.

Now I'm not sure if my car has a physical fault, if my charging cable has a physical fault, if the EVSE is miswired or if my data gathering doesn't work.

I have a 2019 car and the charging cable in the half grey one which is supposed to be three phase I understand.

I suppose the first question: does the i3 support 3 phase charging?

Thanks

Yes it does:

3-fase 16A (11 kW) 400V / 3x16A

You can get it as an option during your car configuration. Unfortunately I do not know if it can be made available via just coding or need an extra HW module.

I believe all i3 94ah on have 3 phase charging you can tell by looking at your charging socket all places have pins. Similarly the charging cable will have sockets on all of 5 pins if is a true 3 phase cable. The actual cable diameter is big as its 32A rated because it copes with single 32A charging and 3 phase 16A

It depends on the market...it's not standard everywhere.

not all/3 (but only 2) phases are properly populated via OBD
as they are split among KLE/EME
