Some grid providers in Sweden are charging separate for peak hours. This makes it very expensive to charge the home battery the same time as the car battery. Also you do not want to charge the car the same time as you discharge the home battery as this would drain energy from the home battery to the car battery.

One solution would be if the component could take the corresponding parameters for the car as for the home and then produce two schedules, possible with some priority flag. Then you could feed you charging box with its own periods that would not interfere with the one for the inverter/dongle/battery.

I did this in a different way. I use EVCC to charge my car when prices are cheap, and use node-red to reduce the battery power to my standard load, when i notice the car is charging with cheap prices (EVCC has an API for poll if it is charging with cheap prices). So i actually more or less disable the battery, while the car is charging, so it maintains its SoC.
