Lower EV Smart Charging Minimum EV SOC does not change duration of expected charging

[Ferrox85]

Version 1.10.0

If for example 50 % of charging is set as goal. I expect that the duration is lowered with 50%. For example from 10 (normally 100%) to 5 hours and that it recalculates the most efficient hours to charge with those 5 hours.

Well, it depends on the current SOC. If your current SOC is 0%, then your example is what will happens. But if you for example have 25% SOC and it would take 10 hours to reach 100% (from 25%), then if you change the target SOC to 50%, then it will take (50-25)/(100-25)*10 = 3.33 hours (from 25% to 50%), which the integration rounds up to 4 hours.

Exactly, but it doesn't do recalculation that when I change the target. So it looks like a bug right?

It is the same for me. Whenever the target soc slider is changed nothing is recalculated. I have to manually turn off and back on the smart charge enable switch to have the integration recalculate a new charge plan.
Actually I have an automation that does this for me.
Would be nice to have this embedded natively in the integration.

Ah, ok. I will check.

In v1.11.0, changing the target SOC will update the charging plan.

Was that the issue, or was there also something else? Hmm. Is it the same problem when changing Minimum EV SOC?

[Ferrox85]

I don't use the minimum setting, but maybe? I can't test it right now..

[jonasbkarlsson]

Now I have tested. Changing Minimum EV SOC will update the charging plan. So then I consider this issue closed.

[Ferrox85]

Just updated to this version, it does not fix the issue. I change the entity "EV Smart Charging Minimum EV SOC" Sorry for the inconvenience, I thought it was an other entity. This is because of some coupled automations and helpers in my HASS.

If I change continues charging for example, it immediately recalculates. But changing the EV Smart Charging Minimum EV SOC entity does not update.

[jonasbkarlsson]

@Ferrox85, I'm not able to recreate the issue. Changes in number.ev_smart_charging_minimum_ev_soc and switch.ev_smart_charging_continuous_charging_preferred should both trigger recalculation, or neither of them. Note that recalculation is not done if current time is after select.ev_smart_charging_charge_completion_time (if not set to None) and the tomorrow's prices are not available.

What other settings do you have for the integration, and at what time of the day do you see this issue?

[Ferrox85]

If I am able to try again I will report back. Currently our car is full...
