Hello,
Since many DC fast chargers are able to read the car battery SOC and display it, I guess there is a communication between the car and the charger, so if this is possible it would be useful to read this value and make it available to control how much percentage I want to charge the car.
Thank you.
I don't have an EV, but that may change.
That said, we don't have to rely on code and protocols for everything.Aren't there other indicators to be had, like:
Interpreting the car's PWM signals.
The magnitude of tail current as an indicator of SOC
Monitoring the amount of kW/h delivered can be interpreted by the user.
Being able to set the amount of kW/h to deliver would go a long way to fulfilling the OP's requirement.
Apologies if you have already addressed these potential features.
