I tried and had no success to go above 125A but maybe I'm still missing a limit.

Re: BMW i3 CCS/charge port controller

Hello, I'm a bit overwhelmed with your questions. I clicked on CAFD, Edit NCD and then the "Functions" page came up. There I found settings for US or EU, LEDs, PWM for the DC contactor etc. but nothing about a 125A limit. Thanks for your reply. Too bad there is no current limit parameter....

Re: BMW i3 CCS/charge port controller

@muehlpower How dit you decode the programmed LIM parameters in E-Sys?
If I try to edit them in the FDL-Editor I don't see parameter names.
Have you been using the BimmerUtility to map the CAFD?

Re: BMW i3 CCS/charge port controller

What small relays did you use? And do you know if there're special requirements for the small relays? It looks like the idea is to put 15ohm resistors (in your case 30ohm), in parallel with the coil of the small ones to simulate the bmw original contactors. But if I remember correctly resistance in...

Re: BMW i3 CCS/charge port controller

How much does your voltage sense board draw? I measured a BMW I3 LIM current draw once it cycles down, it is very low. At this moment however we do not wake and shut it down properly over canbus using the Power Management CAN bus message, 0x12f. It might be possible to shutdown the BMW I3 CCS Contr...

As already written, I use nothing but a Vector CAN card, 12V supply and E-Sys. I have the Fahrzeugauftrag (FA) as a file and do not need to read it from the key. Due to the direct connection with the Vector Card, I don't need a BCD as a gateway either. I don't know how to sort the pictures, so I nu...

I played around with coding the LIM today. I use a Vector CANoe card and E-Sys, with which I can establish a direct connection to the LIM. I also have an FA (Fahrzeugauftrag) as a file, so I don't need another BMW device. After reading out the coding, there are many setting options, such as AC conn...

The wiki states some states which are not implemented in the code. Can anyone confirm that these steps are required to get past the Pre-charge state with a new LIM? The CAN log's shows 0x88 in byte 2 of message 0x12F and the DBC decodes it as "KLR_ON" In https://github.com/damienmaguire/St...

Re: BMW i3 CCS/charge port controller

I would not expect the LIM to actually support charging up to 1000V.
DIN 70121 was limited to 500V and at some point they moved to ISO 15118 which supports 1000V.
But only because the protocol supports it the LIM does not have to...

Only AC_DCO versions work for CCS. (Check if you have a MAC address on the label!)

Re: BMW i3 CCS/charge port controller

As far as different behavior with a 2019 LIM, it is possible that the newer LIM is offering ISO 15118 but it’s up to the station to decide which protocol it wants to speak… Sure the PLC communication could be different between a 2014 and a 2019 LIM, that part we don’t have direct control over. But ...

Nice work! I'm happy there is some progress on this. Which version of the LIM are you using at the moment? Sure the station supports DIN 70121 as well and it should work with all LIM's. But it might be an idea to test a newer version to see if there is a different behaviour. The Ionity logs came fro...

Good question what is pilot status 4 (5% not charge ready) meaning? - Is the Qualcomm chip not ready? (It seems the Qualcomm chip is ready very quickly on the Efacec station) - Is the station sending the 5% PWM but no PLC (charge parameter discovery) which hangs or times out the LIM? - Is a charge r...

I highly suspect something's up in the proximity circuit of Damien's set up. Of course it could be some CAN message that is messing with proximity in some way. I don't know if that's likely though. Other stations should be monitoring PP too. But I suspect ABB is particular about the resistance bein...

Right, resistance testing update. 2k7 between pp and pe : No change to ac or dc charge behavior. ABB stations still say "charging will begin once power is available" and then time out. All other dc stations work as before. Only negative is the cp door flag from the lim stays in error. Pre...

Re: BMW i3 CCS/charge port controller

PP of the vehicle charging port is not connected to the charging station. The PP - PE resistor in the charging connector indicates the AC current capacity of the cable. For CCS Type 2 fast charging it is usually 1K5. That resistance would be measured higher by the LIM if the parallel resistor in the...
