ohh yes, gotcha
So today I completly change EVCS to âspecialâ version. I implemented two relays for multirelay function and also activated it and next I implemented shelly1 relay as switch for CP signal to wake up a Stellantis Opel car.
All functions tested and working, so now Iâm really happy with it.
Hope it will help also to other users.

I made a video to document this issue:
It is clear that disconnecting of the CP line is the way to go.
Victron, could you please make an official retrofit kit for this? You did a retrofit kit to make Multiplus II fan more silent, you could do this as well.
Thank you
Just to make things clear, this is not an issue with the EVCS!
This is just a workaround for vehicles that are not waking up based on CP signal, but are reacting just when disconnecting the cable (or by simulating it)
This is a problem of EVCS and this is a problem of Victron.
Because the EVCS was not tested enough before the release. And Victron Energy did not test EV charging stations of other manufacturers enough. If Victron did that, Victron would know.
The real world is not about âfollowing specificationsâ. The real world is about products, that work properly and are thoroughly tested.
I want to be constructive, so there are my points, that could be fixed in software:
-
When switching from âautoâ to âmanualâ, there is no reason to stop the charging process. Because I have the âautostartâ option ON. EVCS knows that the autostart is ON.
-
When switching from âmanualâ to âautoâ, there is no reason to stop the charging process if all the âauto modeâ conditions are met.
These two modifications could significantly improve reliability.

Hi Folks,
1st post, be gentle :-).
I have a Victron system and EVCS charger. EVCS has been working fine for about 12 months on the legacy firmware. Cam back from a work trip 2 weeks ago and the EVCS has completely stopped working. If I am reading this thread correctly, people are disconnecting the CP relay/fuse inside the EVCS, is that correct?
- Victron Inverter and Solar stack
- EVCS Charger, 2.1 firmware
- Tesla 3 but charger is used for a variety of vehicles.
- EVCS when 1st connected closes the relay (thunk noise) and starts charging. Auto stops after 1-2 seconds.
- System defaults back to âChargedâ when car is clearly not charged
- Assuming its a CP issue but would welcome thoughts.
- EVCS is getting power, as confirmed by the electrician.
Connect the cable and press cp calibration
Sorry, should have mentioned that Iâve done that nearly 10 times with no success.
Do u want to post screenshots of your configs?
The thread is not related with this behavior, it is a modification for vehicles that are not waking up
So you didnât update the EVCS ? It is just happening without having a clear reason, correct? And this is happening on manual mode as well, correct?
For me, it sounds more like a hardware issue.
Are you technical? I can give you some directions for things to test. In my opinion, it is either a ground issue or L1/N are not received by the vehicle. I would start with the second one.
after pressing start, you should hear the contactor closing inside the EVCS, can you measure the contactor input/output voltage ?
Spot on Lucian. I only updated the firmware after the issue started.
The contacter will close after plugging in, it will then deactivate within seconds. I always have had it on manual mode as we run accomodation where people need to be able to charge as needed.
Does the unit need to be open to measure the contacter voltage? Had an electrician neighbour have a quick scan the other day and he was seeing 240v on the large white box inside the unit. However, it was not âonâ at that point. You are saying that I need to measure once itâs plugged into the car?
See images below of config and error. Car starts and then sayâs charged within a few seconds after contactor closing. In this case, car is 89% so should receive a charge.
Tesla Model 3 Plugged in giving error code âExternal charging equipment not providing powerâ âCheck Power source or try different equipmentâ
Car is 89% charged and battery/solar has enough power to charge the car.
Hello Alex
Can you shed some light on how you exactly implemented it? I.e. what materials you used and how you controlled it (timings).
I will try to implement it with for my stellantis Citroen eC4⌠I was about to start investigations this weekend, but then I stumbled upon the answer because some reminder mail from the Victron message board.
Thanks!
Hello h2r,
I did two modifications 
One is implementation of multirelay mode, so I can switch between Single Phase and 3Phase charging. About this modification is on the network a lot of informations.
Plese check this :

Regarding wake up of my Stellantis car, all is described here. Itâs quite simple. Car will wake up when cable is disconnected and connected again. But how to do it remotely ? So I found, that enough is disconnect CP signal. Inside EVCS it is very easy. Itâs this connector :
So I used shelly 1 wifi relay to do it.
So every time when I want start charging, I will open relay and disconnect CP signal for 2 seconds. Car will wake up and charging can start.
Easy
