Amazing update folks. Everything looks good, working without visible bugs (at least I did not find any for last days). As far as I understood for now it’s only redesign, but will be happy to read any release notes or change log if available.
Some improvements that I think make a lot of sense:
Add the ability to disable charge from the battery - only solar + grid. I see the logic as follows:
You activate this feature by toggling checkbox “Disable Charge from Battery”
The system flows all solar energy to, by priority, house consumers, and the rest to the car. If there is not enough energy to fulfill the minimum charging current, then the difference is picked up from the grid.
Get information of car SOC and estimated charging time. I think this information is provided by the car over charging cable, as public charging stations can read it.
Hi @evgeniy.labunskiy, thanks for your feedback.
Unfortunately, the EVCS can’t decide where the power is coming from, for the rest of the system, EVCS is the same as any other consumer. So that config should be part of the GX device. It will be added, but it’s not up to EVCS team.
Then, your second request, that’s not possible as well. The communication protocol that exists between vehicle and charging station for AC chargers, does not contain SOC info. It’s pretty basic - the EVCS “tells” the vehicle what power can deliver, and the vehicle only “reply” if it’s connected, if charging or not. That’s it.
I think that reading SOC from car during AC charging is not possible, only during DC… On previous cars (Zoe and ID.3) I solved it using integrations to Home Assistant and automation for stop charging at desired value of battery SOC.
It will be good to have some integrations for EVs in Node-RED
