Hi,
this could be nice, not only for charge control.
With a Relais you can do a lot of funny things.
Some guys in the Ampera Forum take a GSM Module with some Relais and a 3 FOB. So they can control the Pre-Start/Pre-heat.
Or we find the Bus command for this. ;-)
Bye
Michael
You should be able to implement the relay control as a plugin module, for vehicle modules without charge control.
