System for authorized power connection of power supply with load i.e. electric car, by plug connection in outer socket in e.g. closed garage door in single family house, has control device enabling energy transmission to load at time point

摘要

The system has a load-sided identification device sending an identification signal to a power supply-sided control device after insertion of a plug into an outer socket (102) in a single family house (101). The power supply-sided control device identifies a load i.e. electric car (103), based on the received identification signal. The power supply-sided control device determines a plug-in period for the identified load. The power supply-sided control device enables an energy transmission to the load at permissible plug-in time point. The signal is wirelessly transmitted over a power line. Independent claims are also included for the following: (1) a method for authorized power connection of a power supply with the load by plug connection (2) a control device.
