I am also running into problems with new FW, see https://community.victronenergy.com/t/can-new-ev-charging-software-optimize-battery-use/6921.
On previous FWs in “Auto” mode, if I made start charging, EVCS was waiting in “Low SOC” state and automatically started charging when battery SOC increased above set min. SOC level for start charging.
Now if I start charging, EVCS wait in “Low SOC” state for some time and then automatically switch to “Wait for start” state. Why? It is totally inconvenient! And no, it is not car problem - same car, EVCS, cable,… with different FWs leads to different behaviour…
Very similar inconvenient behaviour is with the moment for stop charging. In previous FWs (some users say it isn’t, but in my experience it just is) if charging in “Auto” mode and battery SOC during charging dropped below set min. SOC level, charging was automatically stopped and EVCS switched to “Low SOC” state.
Now EVCS still continue with charging from battery when battery SOC is lower than this level. Due to my observation, this is related with automatic reset of countdown counter, which is reset every-time if battery status is changed from “Discharging” even for very short time and leads to discharging battery to much lower SOC level compared with previous FWs.
Also with previous FWs it was possible to left car connected to EVCS and left EVCS in “Auto” mode over night. EVCS was waiting in “Low SOC” state and next day automatically started charging when battery SOC increased above set level.
Now it is not possible, because EVCS is everytime automatically switched to “Wait for start” state and charging needs to be “manually” started. Also for example it is not possible to make start charging in the morning and left EVCS wait in “Low SOC” state for automatic start charging based on battery SOC.
I love Victron products, there are great and high quality products, but a lot of made changes in FW for EVCS does not lead to better (or at least same) behaviour…
But your problem is I think related to the car, because after you made start charging, EVCS is switched to “Charged” state. I had very similar problems with previous Renault Zoe and also VW ID.3, when charging did not start after some time after connecting cable to the car. With the actual car (Tesla Y) I no longer have this problem.
