You are missing a semicolon the end of  "end when" and the conditon of when should be boolean comparison, i.e PNet == 0. so more or less you code should look like this

when PNet == 0 and PNet <> pre(PNet) then

  cn = pre(cn)+1;

end when;

hope it helps. Cheers

Thank you very much for this.
I was able to save the code without errors but I cannot run the simulation as there are 2 errors:
1. It is not allowed to use pre for a continuous time variable outside a when clause:
pre(PNet)
and
2. The when-condition must be a discrete expression:
when PNet == 0 and PNet <> pre(PNet) then
cn = 1+cn;
end when;

Any ideas on this?

HI, is it possible to share you model?

Here is the library:
https://github.com/UdK-VPT/BuildingSystems

I am working on Complex battery model which is located at Building Systems/Technologies/Electrical Storage.

I am trying to count the number of cycles the battery is going through and the depth of discharge of each cycle.

A simulation without these features can be run and this can be found at Building Systems/Technologies/Electrical Storage/Examples.

Hi, so i copy the example and add a variable Counter

Integer Conter_1C(start=0,fixed=true);

and following equation

when battery_1C.PNet == 0 and battery_1C.PNet <> pre(battery_1C.PNet) then

    Counter_1C = pre(Counter_1C)+1;

  end when;

and after the simulation got Conter_1C = 43, which i think the right number of times when PNet equal to 0 before being cahrge. Hope it helps you.

Cheers
