You now can’t use the Smartpass consumer output

Relay it seems to be internal to the inverter. ??? NOt sure . But on the parts list there was no relapy .
GEts controlled by the Body COntrol module which does the switching.
will have more info once the inverter gets here .

Could well be indeed if it is build on purpose, but what is this connector for:

I thought for the relay (inside or outside the invertor), but didn't check yet if it gets 12V when the motor is running.

I think if you measure the voltage should be variable or pulsed and not exceed 3.5v .
Have not taken the panel off yet myself . But i am
Pretty sure that is the case .

You are right, see my post of June 5 here.

[EDITED] you are clearly an expert

Far from it just a guy with too much time on his hands apparently lets hope in don't burn the Gren to the ground watch this space for updates .

Love it when a plan comes together !!!!!! Ahahhahah .
Come on ineos just send the inverter already .
Below the voltages to expect from such a connector .

I have a digital oscilloscope, to be connected to my computer, perhaps I should use it to check, but I need the invertor to power my computer

(An extension electrical cable to my house will also work )

Ohh yeah that is next level Jean !!!! Would be useful to know . Looking forward to it .

1. when you leave the car long enough "at rest" you get a voltage of 1.16 Volt (see the first part of the graph).
2. as soon as you do something, like opening a door or putting the contact on, with or without the motor running, you get an erratic voltage fluctuating mainly between 1.5V and 2.5V.
3. and then you get sometimes huge peaks of more than 200V, but in my opinion these are "transient" errors, and no real measurements.

• I really don't know what this signal means (@Tinki : can you explain or make a guess?)
• Next time I should read my oscilloscope manual again, because while writing this post, I see some improvement possibilities for the measurement.

OK, today was a dry day, no planned assignments. Yesterday I got my Anderson plugs and I wanted to continue the installation of my compressor. But I decided to play around with the red-blue-black connector (see my picture above).

First I used a (Chinese) multimeter with memory function. Beware, the minus sign means the upper pin is "ground", the lower is the "positive".

Sampling rate was one measurement per second, I could rise it to twice per second, but that didn't make a difference in the pattern.

So what did I see:

1. when you leave the car long enough "at rest" you get a voltage of 1.16 Volt (see the first part of the graph).
2. as soon as you do something, like opening a door or putting the contact on, with or without the motor running, you get an erratic voltage fluctuating mainly between 1.5V and 2.5V.
3. and then you get sometimes huge peaks of more than 200V, but in my opinion these are "transient" errors, and no real measurements.

I started the measurement again with my digital scope. Sampling rate is 20ms, fastest sampling that t can do.
I could download the data, but to be honest, I didn't understand the format (long time I didn't use the scope).
And I had to stop my experiments, because I got a call for an unplanned assignment.
But, I have a picture of the screen:
View attachment 7832734
On the screen of the scope I don't have the scale, but I guess the lower points are 1.6 Volt, and the higher points around 3Volts.
When leaving the car at rest (not doing anything apart from the measurement) the "quiet" periods around 1.5 Volts are longer, but there is no definite pattern or lengths, it varies.

Conclusion:

• I really don't know what this signal means (@Tinki : can you explain or make a guess?)
• Next time I should read my oscilloscope manual again, because while writing this post, I see some improvement possibilities for the measurement.

Jean my friend with out me beeing a professional in the area i will give it a stab and say this confirms my suspicion that the connector is from the CAN bus . The CAN bus will be controlling the inverter and cut it off in case of low battery voltage or other issues . If you see the picture i attached in the previous comments it is almost identical to the one from your oscilloscope (osmeloscope for the AvE (Arduino vs Evil youtube channel , check it out will not be disappointed) fans out there ) .

Thank you for taking the time and confirming . You are a truel legend ! Much appreciated.
Once i have the inverter i will do a write up .

• what is the CAN bus doing?
• why is it fluctuating like this, while my batteries are OK?

Jean Mercier said:

Yes sure, it looks like your inserted graph.

My degree is translated in English "Master in Electronic Engineering", but I only worked two years in electronics, and it was even research on semiconductors.
Therefore my real "electronic" experience is very very limited and "old", therefore I am not a professional. But I still like to understand!

What I don't understand:

• what is the CAN bus doing?
• why is it fluctuating like this, while my batteries are OK?

I am really a complete novice in this

@Tinki in the meantime I did a diagonal reading of the Wikipedia page on the CAN bus.

Your highway definition is OK, and the voltages I measured correspond to the CAN bus standard.

Therefore, I think that what I measured are signals coming from several devices in the car, and when I leave the car "at rest" unnecessary devices disconnect, therefore my frequency of peak 3V voltages disminue.

If the "INEOS" inverter needs to be connected to the CAN bus, this means it is an intelligent inverter, I mean with some kind of microprocessor inside.

Mine is a simple electronic inverter, no "computer " inside. Therefore if I want to connect it, therefore the CAN bus connector isn't useful for me.

Still a lot of guessing here, but thanks @Tinki and others for improving my knowledge, including those who already left the forum

You have been the most brave man . You disassembled a brand new car to show us what is possible, if it was not for you I would had no idea of the connector .
In short its your fault , thank you for that

I am getting more and more excited about this !!!
