Check why static limit is disabled on Delta charger (supportStaticLimitationForChargingStation = true)

[OliveGerste]

The slider component in static limitation checks for AC Charging and disable it, if Type is DC:

Ok, you can remove this constraint. Thanks!

@OliveGerste Hi, Tobias, Could you please provide me an update on this? It is just about one line of code right?

Thanks, Fred

@fcoutellier Hi Fred, I took the line out, but it does not work right away. The limitation dialog looks like this:

So some more investigation and adjustment is needed. (I do not want to break anything)

My focus is currently on the issues with high prio. But if you want I can finish this tomorrow?

[LucasBrazi06]

It is probably related to the number of phases in the Watt calculation. It has to be simplified with 230V. Check in the whole project that we don't use 400V anymore.

[OliveGerste]

@LucasBrazi06 I adjusted the Watt calculation method, but if we use dc-charging we have to use 400V for the calculation right?: (Should we use the voltage property of the connector to calculate for dc-charging here?)

Now we get the following values in the dialog:

The two problems I see, is that we add up the amperage limit of the two connectors, which in this case is not correct right? (charging station max power : 150kW) The other thing I do not understand is why we have an amperage limit of 400A per connector. If 150kW is the maxPower, the max Amp should be 375 or am I wrong?

@cybergege Could you check this use case and provide your feedback ?

Hello, this needs to be discussed in a meeting: -Need to check if U-400v and V-230v are required or not, same with Gireve (Sebastien) -Need to check if AC/DC cases needs to be treated separately: AC = ~Amps / DC= ~Amps + ~Voltage

I scheduled a meeting.

About AC: The CAR EVCC is Controlling the Drowing of the Current AC (I / Amps) -> From OCPP perspective, we only control the Current A (8 to 32A or more for Zoé).

Power Calculation depends on the Voltage Reference: V = 230v (Phasis-Neutral) / U = 400v (between phases) P= U x Sqt(3) x I AND U= V x Sqt(3) P= V x Sqt(3) x Sqt(3) x I ->> P= V x 3 x I

Example P = 230 x 3 x 32 or P= 400 x Sqt(3) x 32 Another question: What is Gereve's reference 230 or 400 ?

[cybergege]

About DC: The Charger EVCC is Controlling the Drowing of Current (I / Amps) + Voltage (V) in DC -> From OCPP perspective, we only control the Current A (0 to 400A or more if possible).

Power Calculation is totally different. It depends on V (0 to 400V) and I (0 to 400A) and Limitation of connector (Kw). P = V x I Another question: What is Gereve's reference A x V or Kw ?

I'll write the minutes and next steps as discussed during our meeting this afternoon.
