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 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 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
