Re: AC Charger Inlet Types - swappable?

Mon Oct 29, 2018 2:13 pm

I am wondering whether one of these Combo 2 socket inlets can replace my Combo 1 socket inlet on my BMW i3 94AH - AU$360.
I have read that Combo 1 and Combo 2 use the same fast charge communications protocol. So is it just a matter of connecting wire for wire except for L2 and L3 which Type 1 does not support.
CP to CP, PP to CS, L1 to L1, N to N, DC- to DC-, DC+ to DC+, PE to PE.
The DC fast charge communications is done over the CP wire.
I suspect that maybe my BMW i3 needs to be re-programmed to accept the slight difference in protocol.

Setec Power tell me they sell stacks of their Adaptors to Norway. https://drive.google.com/open?id=1NUo4v ... v8TJDE3XC3. I decided to get an adaptor instead of doing a retrofit on my BMW i3.

As I understand it, the communications protocol when doing a CCS charging session is carried out over the L1 and L2 lines...the other interlock lines are still used, similar to the way they are during an EVSE charging session. Maybe I need to reread the specs...it's been awhile.

I am not sure either. Here is a photo of my Type 2 plug of my CCS 2 to CCs 1 cable adapter. It still has the CP (control pilot) wire connected from the Type 2 plug through to the Type 1 plug. The CS or PP pin is not used as it's only purpose is to inform the EV it has a EV plug connected which is done at the Type 1 plug end which plugs into my BMW i3.

The Type 1 plug end of my adaptor still uses the 3300ohm and 1500ohm resistors together with a microswitch to signal to my EV that a EV plug is connected. Everything else is straight forward. Nothing special just the standard J1772 circuit.

The only real value of the CCS adapter is the high DC current carrying capacity of the pins and the use of multi-stranded flexible wires and it's waterproofness.

Going by the CCS adaptor wiring replacing the old CCS 1 plug inlet with a CCS 2 plug inlet should be straight forward. Except not having L2 and L3 connected will probably limit the maximum charge current to about 15A if using a normal level 2 EVSE cable and type 2 (non-CCS) charging station.

DC Fast free Charging using 50kW charger at Mittagong RSL. Only took 10 minutes to charge from 45% to 95%. Seriously awesome, that is fast!!!!

Has anyone on here actually swapped their CCS1 for the CCS2? There's not a lot of info out there and it looks do able.

did you managed to get this adaptor? can you pass me the url to get it online?

Where are you located?

A shop in Lithuania is doing the conversions commercially. Website says it takes two days. Certainly do-able but maybe not an easy DIY.

If you are in the UK, you could try asking Indra. If they can't do it they might be able to refer you to someone who can.

Its quite easy. In most cases, all u need is to swap the wire+charge port and thats it

Working on the car on and off while using it as my daily commuter, it's all completed!! As it was said, it's easy, but only once you know how. It also involves coding of the car, bimmercode won't do it, and pending on the year of vehicle the wires won't be a straight swap. Not a DIY job unless you have a solid background in electrical and comfortable coding the car.
