Waiting on vehicle

[TijsDeBelie]

Description

Polestar, Guest vehicle and vehicle without API are all waiting on vehicle when trying to charge.

Steps to Reproduce

1. Connect car to charger
2. Open evcc and change to fast charging or smart (with settings so car will charge)
3. Wait for something to happen
4. Car (polestar) displays as waiting for car
5. Change to guest vehicle or vehicle without API
6. Still waiting on car

Version

v0.209.7

Did you follow the steps from https://docs.evcc.io/en/docs/devices/chargers#eve?

The "Active load balancing" license is required for external Modbus control of the charger. Enable "Active Load Balancing" and select "Energy Management System" as Data Source in the configuration. It is recommended to set "ValidityTime" ("TCP/IP EMS" menu) to 300s.

[TijsDeBelie]

Hi,

• It has worked before
• I have the active load balancing licence.

I did follow the steps in that guide 😄

I do see that the charger received commands. However onIy to charge at 3.8A, and since the car needs minimal 6A this fails.

It has worked before

What changed? If it was a evcc update, does a downgrade fix the problem?

[TijsDeBelie]

There was an update to the Alfen Eve app, and Polestar updated their app today. However, there's no new firmware. I also haven't updated to the latest version of EVCC.

The only thing I see that seems very odd is that Polestar reports as not connected, but it is physically connected. The charger is also waiting for power and not getting it from EVCC.

I already tried to downgrade to an earlier software version of the charger. The latest version was only released recently and could have unexpected errors. However, this did not fix the issue (but it did work last week).

What changed?

Basically nothing. EVCC was disconnected for a few days because I transferred the Raspberry Pi board into a case and added a fan.

Since reporting this, I have played a lot with the settings, but no solution yet. The settings are back to a working state.

Please create a logfile that shows the moment you connect the car and you attempt to start charging.

There seems to be an active ocpp charging limit. Is the wallbox connected to a backend?

[TijsDeBelie]

It's only connected to last mile solutions to send the charging sessions. No other backend

[mfuchs1984]

This is an ocpp backend as far as I can see. You need to get rid of the ocpp charging profile. On some chargers, it can be deleted manually in the web interface. Another option is to do a factory reset of the charger or to disconnect from the backend, connect to e.g. evcc or home assistant ocpp and start a fast charge there, then reconnect to the other backend without stopping the fast charge.
