Method for transmission of electric energy, supply facility, household appliance and system

A supply facility for a household appliance, the supply facility comprising:

• a terminal for producing an electrical connection to the household appliance;
• a controllable power source for providing electrical energy through said connection;
• and
• a processing facility configured:
• to delimit the electrical energy provided through said connection to a first predetermined amount,
• to determine a temporal progression of the electrical energy transmitted through said connection,
• to terminate the delimitation to the first predetermined amount when the temporal progression corresponds to a predetermined temporal progression, and
• to electrically evaluate a transient response being a switch-on or switch-off behavior of an electrical consumer, in order to determine the temporal progression.

A household appliance for connection to a supply facility, the household appliance comprising:

• a terminal for producing an electrical connection to the supply facility;
• an electrical energy storage device;
• a controllable electric consumer configured to be operated with electrical energy from said connection;
• and
• a processing facility configured:
• to operate said electrical consumer according to a predetermined sequence with electrical energy from said connection, resulting in electrical energy transmitted through said connection following a temporal progression, the predetermined sequence including switching said electrical consumer on or off, and the temporal progression including a turn-on or turn-off transient behavior of the electrical consumer;
• and
• to charge said electrical energy storage device by using the electrical energy from said connection.

A system, comprising:

• a supply facility for a household appliance and a household appliance for connection to said supply facility;
• said supply facility including:
• a terminal of an electrical connection to said household appliance;
• a controllable power source for providing electrical energy through said connection;
• and
• a processing facility configured:
• to delimit the electrical energy provided through said connection to a first predetermined amount,
• to determine a temporal progression of the electrical energy transmitted through said connection,
• to terminate the delimitation to the first predetermined amount when the temporal progression corresponds to a predetermined temporal progression, and
• to electrically evaluate a transient response being a switch-on or switch-off behavior of an electrical consumer, in order to determine the temporal progression;
• and
• said household appliance including:
• a terminal of said electrical connection to said supply facility;
• an electrical energy storage device;
• a controllable electric consumer configured to be operated with electrical energy from said connection;
• and
• a processing facility configured:
• to operate said electrical consumer according to a predetermined sequence with electrical energy from said connection, resulting in electrical energy transmitted through said connection following a temporal progression, the predetermined sequence including switching said electrical consumer on or off, and the temporal progression including a turn-on or turn-off transient behavior of the electrical consumer;
• and
• to charge said energy storage device by using the electrical energy from said connection.
