Sorry - above is not my current config, i've attached it here but the changes i've made has nothing to do with the problem mentioned config.txt
Try to reduce the interval
as low as possible without getting into unstable grid metering values after charge current modifications.
Most systems allow for intervals in the range from 10 to 20 seconds. Some even lower. Only some very slow systems like Huawei with dongle require long intervals.
The two cars are differentiated via NFC and activated at the wallbox
We can only differenciate sessions if we see a status change. The wallbox will see that electrically, evcc only though API polling. If you go from B->A->B and evcc only sees B->B then there's nothing to detect.
Describe the bug
I have two cars, on PHEV and one BEV. I have often had the impression that something is wrong with the charging protocol. And today I finally have the evidence. One of my cars was loading with SoC set to 90% and I came home and unpluged this car and started to load the other car I just got home with. After a few hours I looked into evcc how charging is going and I saw that my Tuscon with a 13,8kWh batterie capacity has loaded 28,8kWh and still going and the SoC was set to 90% (no SoC-Limit is set for this car). Because my Wallbox (Tinkerforge WARP3) logs charging sessions too, i compared it with the log sessions from evcc. The running session is not log in session log, but my wallbox shows a new charging session. Wallbox session: e-up 29.06.2024 10:07 - 15,057 kWh 06:35:35 Wallbox current session: Tuscon 29.06.2024 16:43 - 6,887 kWh 06:16:45 - still running evcc current session: Tucson - 29,3kWh 17:38h - still running As you can see in the log of evcc at 16:43 the car was changed but no new charging sessions was started.
The two cars are differentiated via NFC and activated at the wallbox
I think it has to do with time between unpluging the first car and pluging the next car. Interval is set to 30s.
I never discover this effect, when there are minutes or hours between unplugin one car and plugin another car.
