Charging L2 L3 reporting false - 1.6.5 #151

Closed deqw closed 1 year ago

deqw commented 1 year ago

While 3 phase charging (1.6.5) the sensors Charging L2 and Charging L2 are reporting false and Charge in the web GUI reports 1 x 13.0 A. Attached some screenshots of the situation. Is this correct?

Is your car a Tesla by coincidence?

deqw commented 1 year ago

No it's a BMW iX3.

dingo35 commented 1 year ago

Perhaps you can post a verbose telnet log? It could be a bug, but similar behaviour happened with a Tesla that started drawing current on a single phase and only after 11-25 seconds it started charging over the other phases...

EDIT especially the first 11 seconds of the charging session, when phase detection is running, are interesting.

But at the moment of the screenshots it was already charging 3 phase for 21 minutes and drawing current on L1 L2 L3 from the start/1st second.

I noticed this morning that without charging and with or without the cable connected to the car:

Then I did a reboot via the web interface (no cable connected) and it changed to:

Is this the correct reporting for L1, L2 and L3 in this situation?

Those booleans only have meaning during a charging session.
