Further to the work undertaken on the Rear High Voltage Junction Box ("HVJB") by Jeff and Kenny (here), I've taken a look inside the 'AC switch box' which is attached to some
confused
of the Model S supplied in the European market.
I believe the sole purpose of this hardware is to automatically switch the AC input (from the charging connector) to the charger power modules, either one module per phase (three phase input) or two modules in parallel (one phase input)
Note: this hardware does not support dual chargers.
