Add a switch or other mechanism to not interrupt HPC-charging #298

Closed maeklund86 closed 3 months ago

maeklund86 commented 3 months ago

Is your feature request related to a problem? Please describe. I accidentally forgot to switch off the smart charging, and connected to a HPC-charger (100kW). The automation then of course programmed the cheapest hours as expected and stopped the charging.

Describe the solution you'd like It would be nice to have an option to not interrupt charging sessions once the power exceeds X kW (typically 11 kW). Alternatively a way to smart charge only at certain locations like home etc.

Describe alternatives you've considered The alternative is to remember to turn off the smart charging when headed to a HPC.

Just write a simple automation to enable smart charging then the car is at home, and disable when the car is away.

The intented way to handle this is to write an automation that controls the switch.ev_smart_charging_ev_connected. This will prevent the integration to interfer with HPC-charging.

maeklund86 commented 3 months ago

I ended up doing just that. In my case the car integration provides a sensor for charging speed. I created an automation that switches off the switch.ev_smart_charging_ev_connected if the power is over 11kW. This is probably something that most people will want to add, maybe an addition to the documentation would suffice.

You should rather automate when switch.ev_smart_charging_ev_connected gets turned on. In my case I can use the switch sensor from Easee to turn it on (when car is connected to easee charger, turn the ev_connected swith on). You could do the same, or use device tracker as an alternative. Or if you can get the information from the car that it is connected to a charger (when car is home and charger is connected, turn on ev_connected, else turn off ev_connected).

The 11 kW option is at best a workaround, for me that would not work as I can charge 22kW at home.

Hmm, you might be right. I don't want the smart charging to be active when charging at a public charger, (which can be an 11 kW charger) but I do want the smart charging active at my parents' house as well as my home. My car integration reports when a charger is connected and power provided. Need to think further

Just add a zone at your parents home, and set the automation to enable ev_connected if the car is connected and is home OR zone_parents.

@corvy This was good advice, never found a use for zones before. I added a condition to the automation that the position can not be "Away". That way adding new zones will automatically be included for the smart charging. Thanks a bunch!
