Re: BMW i3 CCS/charge port controller

This problem is still there, tried with another station of the same kind. I've seen that tom91 had exactly that problem where the precharge voltage was there but contactors wouldn't close. I think Jack Bauer pointed him that he did set the maximum A in 0x2F1 to 0 which apparently was the cause. Thi...

Re: BMW i3 CCS/charge port controller

one more question, in anticipation of the next step, my current sensor reads a positive value when I use current from the battery when driving, and a negative current when I charge. so when i go to charge it will report negative current to the lim, is this correct or not? Positive amperage is charg...

You should hear them click. Are you sure it's carried out? How is the 0x272 message behaving?

Re: BMW i3 CCS/charge port controller

thanks for the answer I understand that I have to make a request for the Amp needed in the message 0х112 d0 and d1 and this request must necessarily correlate with the request in Watts from the message 0х3Е9 d0 and d1 Message 0x112 comes from the BMS and should the be the actual amperage. Not the w...

Charging is a positive amps value. So if you e.g. charge with 100A it will be (100 + 819) * 10 = 9190 -> 0xe6 0x23

Re: BMW i3 CCS/charge port controller

Bytes 0x00 and 1x00 in message 0x112 show battery current and in all your logs normally it is mentioned 0xf9 and 1x1f, are these indicators stable (fixed) or these bytes have to show real values? Byte 0 and 1 are battery current, right. Note that it has a factor of 0.1 and an offset of 819. So 0xf9...

Re: BMW i3 CCS/charge port controller

Meh, my LIM stopped locking the charging port when I plug in 😕 I measured the lock, it’s 1 kΩ unlocked, 11 kΩ locked as it should be. I checked the connection cable: fine. Fun fact: when locking manually, it does unlock by itself when done with CCS charging. So it should not be any cabling. What co...

In case of CCS I simulate a CHAdeMO charge. In case of AC it will switch to the onboard stock charger immediately. So in both cases you won't be able to drive away.

If I decide to switch CC and CP signal with a relay, what would be the indicator for the relay to know if it's open or closed. Which signal can i use to recognize if a Type2 or CCS plug is plugged in? I actually do this for my Nissan Leaf. I.e. switching CP/PP between LIM and the stock charger. Def...

On Efacec it stops after some seconds of actual charging. But investigating... I made a log...

Re: BMW i3 CCS/charge port controller

You have 2 issues one is timing based and the other is isolation based. I have resolved both in my version of coding. Timing: if(Cont_Volts==0)lim_stateCnt++; //we wait for the contactor voltage to return to 0 to indicate end of cable test if(lim_stateCnt>20) { if(CCS_Iso==0x1) lim_state++; //next ...

Re: BMW i3 CCS/charge port controller

If you know you have issues with Chademo stations then this is most likely your issue. Please obtain an isolation tester for better information. It's just one certain one on wet weather. Nothing else. We did not had these kind of problems the last days. But yeah, I get the idea. Dala from Dala's EV...

That is your call to make if you are not confident in your understanding and ability, do not do any of this.

I have seen this issue before as you can see in the thread and it was isolation related.
