refresh of battery status when car is parked

[AprilWexler]

Hi,

I would like to understand how often the battery-status gets refreshed in HA? I read in another thread that no info will be sent if car is parked. Is that really true?

I am asking because I used to check the battery status during charging - and would like to stop charging when ~80% are reached. This was working for me with the former Integration from "JjyKsi".

I tried to continue with that using that wonderful new integration by kvanbiesen and found out that there was no refesh often enough to stop charging at ~80%.

I can see two sensors:

sensor.battery_ev_predicted_state_of_charge
This one seems to be refreshed only, if car was waken. Right?

sensor.battery_hv_state_of_charge
This one got a refresh after ~30 minutes. Too less for my purpose.

Is this something related to the integration or with BMW? Is there a difference between the two mentioned integrations?

Thanks for reading my question,
thanks for the integration,

best, Kai

BMW doesn't send battery update as much as we would like. There is not much we can do about it, if BMW doesn't send it, we are blind. We could use learning from position and median usage, but I doubt this will be efficient.

I am planning a more predicted sensor for BEVs, but that will need extensive testing.

We can , but then people with mutiple cars run into issues....i've created a semi midway point for now

Why not setting the charging limit in the car to 80% then?

because that feature is not available in a PHEV.

Makes sense (but you die not mention that initially).
