EV Ladestation zu wenig Leistung?

Hallo

Wir versuchen seit ein paar Tagen eine EV-Ladestation in betrieb zu nehmen.

Die Ladestation ist in ein ESS System integriert.

Firmwareversion 1.24

Wenn wir einen BMW i3 anschliesen und mit der ladung beginnen bekommen wir im Fahrzeug sofort die Fehlermeldung (Ladeabbruch.Netzleiszung zu gering)

Der Max. Ladestrom ist auf 16A eingestellt.

Das laden funktioniert im manuellen und automatik Betrieb nicht.

Hat vielleicht jemand eine Idee woran das liegen kann bzw. was der Fehler sein könnte?

DANKE! Sg ANton

Es ist ein ESS System mit 3x Multiplus 2 48/5000 und einem MPPT 450/100 in kombination mit einem Cerbo GX und einem 28kWh Speicher.

Die EV Ladestation ist bereits über Modbus mit dem GX verbunden.

Die Ladestation ist als Drei phasen system ausgeführt.

Hello

We've been trying to get an EV charging station running for a few days.

The charging station is integrated into an ESS system.

Firmware version 1.24

If we connect a BMW i3 and start charging, we immediately get the error message in the vehicle (charging aborted, network power too low)

The max. charging current is set to 16A.

Loading does not work in manual and automatic mode.

It is an ESS system with 3x Multiplus 2 48/5000 and an MPPT 450/100 in combination with a Cerbo GX and a 28kWh storage.

The EV charging station is already connected to the GX via Modbus.
The charging station is designed as a three-phase system.

Does anyone have an idea what could be the reason or what the error could be?
THANKS! Sg Anton

Try to lower the current to 6A. The charging station is not affecting the power in any way. There is just a contactor between the Grid or Inverters and the Vehicle.

But is it starting when you press start on the charging station? Do you hear the relay closing inside the charging station? Can you provide more details?

Hello! When we plug in the cable to the car it locks. But we did not hear a relais when we start charging. After about 12s there is the error and the conection gets unlocked.

The system now works perfectly, the reason was a loose plug from the control of the relays that switch through the 3 phases. Many thanks to Lucian Popescu (Victron Energy Staff) who helped me a lot online. All after work. Many thanks to Lucian and Victron


Die Anlage funktioniert jetzt perfekt, der Grund war ein gelöster Stecker von der Ansteuerung der Relais die die 3 Phasen durchschalten. Herzlichen dank an Lucian Popescu (Victron Energy Staff) der mir Online super weitergeholfen hat. Das ganze nach Dienstschluss. Herzlichen Dank an Lucian und Victron
