Determining device, method for determining of transmitting parameter, energy transmitting device and method for wirelessly transmitting energy

An energy supply device, comprising:

• a determining device for determining a transmission parameter of a wireless energy transmission from a sending device to a receiving apparatus, the determining device comprising:
• an authorization checking device which is configured to carry out an authorization in order to determine whether the receiving apparatus is authorized to receive energy from the sending device;
• a sending/receiving apparatus which is configured to send and receive messages during a message exchange with the receiving apparatus in order to determine the transmission parameter;
• and
• a parameter determining device which is configured to determine the transmission parameter based on the authorization and based on the message exchange, if the receiving apparatus is authorized to receive energy from the sending device, wherein based on the transmission of a test message between the receiving apparatus and the sending device, pulse responses of the transmission channels between the sending device and the receiving apparatus are determined.

A method for determining a transmission parameter of a wireless energy transmission from a sending device to a receiving apparatus, the method comprising:

• carrying out an authorization in order to determine whether the receiving apparatus is authorized to receive energy from the sending device;
• sending and receiving of messages during a message exchange with the receiving apparatus in order to determine the transmission parameter;
• and
• determining of the transmission parameter based on the authorization and based on the message exchange if the receiving apparatus is authorized to receive energy from the sending device, wherein based on the transmission of a test message between the receiving apparatus and the sending device, pulse responses of the transmission channels between the sending device and the receiving apparatus are determined.

An energy transmitting device for wirelessly transmitting energy to a receiving apparatus, the energy transmitting device comprising:

• a sending device configured to radiate energy by means of energy sending signals;
• a receiving device configured to receive a message from the receiving apparatus, from which the amount of energy which has been supplied to the receiving apparatus using the radiated energy can be determined;
• a comparing device being configured to compare the amount of radiated energy with the amount of energy supplied to the receiving apparatus;
• a controlling device being configured to control the sending device to radiate energy by means of other energy sending signals optimized for the energy transmission from the sending device to the receiving apparatus in accordance with estimated pulse responses of the transmission channels between the energy transmitting device and the receiving apparatus if the ratio of the amount of energy supplied to the receiving apparatus and the amount of radiated energy is below a predetermined threshold.

A method for wirelessly transmitting energy from a sending device to a receiving apparatus, the method comprising:

• receiving a message from the receiving apparatus, from which the amount of energy which is supplied to the receiving apparatus via energy radiated by means of energy signals can be determined;
• comparing the amount of radiated energy with the amount of energy supplied to the receiving apparatus;
• and
• controlling the sending device to radiate energy by means of other energy sending signals optimized for the energy transmission from the sending device to the receiving apparatus in accordance with estimated pulse responses of the transmission channels between the energy transmitting device and the receiving apparatus if the ratio of the amount of energy supplied to the receiving apparatus and the amount of radiated energy is below a predetermined threshold.
