Errors in simulating Evcs

EEMChula · October 14, 2023, 4:57am

Hello folks,

I am beginner of OpemEMS. I am trying to implement simulator evcs. It appears in UI but the errors show the below:

Could anyone give suggestions? Thank you very much in advance.

Without the Code or the “Parts of Interest” it is not easy to Debug i need to say - maybe provide the Code so we can have a look

Hi @Sn0w3y ,

Thank you very much. Actually, I didn’t modify the code. I just tried to implement simulator EVCs as shown below:

Are there any documents to implement EVCs?

Thanks again.

Hello,

i quote @tsicking:

I just checked it myselt. There is indeed an error in the implementation of the simulated Evcs: The channel ACTIVE_CONSUMPTION_ENERGY exists in both, ElectricityMeter.ChannelId and Evcs.ChannelId, so you have a duplicated ChannelId, and the constructor throws an exception.

I don’t know what the easiest solution to this is. Maybe, for the moment, you simply rename the channel in the Evcs-interface to EVCS_ACTIVE_CONSUMPTION_ENERGY or something? Or does someone else have a better and similarly short solution?

Best regards,
Thomas

Thank you very much @Sn0w3y for your support.

Thank you for reporting this. It will be (quick-)fixed in FEMS Backports by sfeilmeier · Pull Request #2446 · OpenEMS/openems · GitHub, concretely here:

Regards,
Stefan

Forgive me for hijacking this thread but I was about to pose a question about the Simulated EVCS but I thought the errors above were related to the fact that there is no option to provide a datasource as with other simulator services. I have attached a screenshot of both the Simulator EVCS configuration window as well as the Simulator PV-Inverter window. If the missing datasource option in Simulator EVCS has nothing to do with the issues above, I apologize.

Hi @acabrera and welcome to the OpenEMS Community.

No, in fact your question has nothing to do with the above. Don’t be afraid to open up a separate thread for your future questions.

The simulated EVCS is not intended to “replay” the data of a datasource, but it is used to test EVCS controllers that actively control the EVCS. In that regard it is very different to a simulated Meter. What is the actual use-case you are trying to solve?

Regards,
Stefan

Thanks, Stefan. Please disregard the above, I was experiencing errors with the EVCS simulator and thought the issue might be with the datasource. I was just poking around trying to better understand OpenEMS so no need to dig further into this one.

I have begun the process of setting up OpenEMS for a client and I am slowly learning the ins and outs of this framework. I did post a separate forum question about an error I am getting trying to run the GitPod simulation and I just tried it again with a similar issue for Task 2 (OpenEMS Edge build): Live-Demo on Gitpod Build Error
