Loading with 3.6kW instead of 11kW

[rhpijnacker-philips]

Describe the bug

I have a 3-phase Wallbox Commander 2 charger, which can do max 16A per phase.
When I would load at max capacity, it would show 11kW and 48A in the UI.

Now, with 0.8.4 it seems to be limited to 16A and I only load at 3.7kW max.

To Reproduce

1. Set the max capacity (per phase) to 16A
2. Start loading

Expected behavior

The charger loads with 16A per phase.

Are you sure it's not the vehicle limiting power - Power Offered is 11kW in your screenshot.

I don't have a three-phase charger, but I often see Current Offered at 32A. but Current Active Import at less - like 31A

I am not sure, because I do not know how to verify this. However, I do not see a reason why it would be. At the time this happened the solar panels were generating more power than the charger was using.

EVs will reduce their current draw as they approach 100% SoC

Actually as I look at this again, it looks like the charger has dropped back to single phase: 15A x 230V is roughly 3.5kW

As far as the charger is concerned, it is offering 11kW (so three phase) but the car is only charging on one phase.

Suggest that you turn on debug logging, and power cycle the charger and attach the logs - that might provide a clue as to why only single phase is being accepted.

Make sure you start a charging session and include that in the logs.

The SoC was about 50%, so I do not think it was that.

Somehow, the new charging cycle is back to 11kW.
I'll keep an eye out for this. If it happens again, I will try to collect the requested logs.
