Is there any interest in a DIY project to add a time-of-use timer system to the Siemens Versicharge? It's something that could fairly easily be done without any permanent or serious modifications to the charger. Here's some background:
There is a terminal block inside the Versicharge that's intended to allow remote control of charging availability. When this signal is engaged, the "remote" light on the front panel will light up and charging will not occur.
If you were to connect this signal up to a clock, then you could easily have your car charge when the rates are low (if that's something that affects you).
I'm fairly confident that a small Arduino-based system could be devised to do exactly that, and the result would be something that would be easy to build, cheap and perfectly effective. I don't mind doing it, but I don't want to bother if nobody would want one.
