Method for transmitting charging signals via a data transmission path using resonance phenomena The invention provides a method for transmitting charging signals, in which an electrical resonance effect is provided, with an output current (100) being emitted from a line current driver device (202), which output current (100) is passed through a data path filter block (201), which has a data transmission path unit (122) and a matching filter unit (123), to a line impedance (102), and the matching filter unit (123) and the data transmission path unit (122) are set such that an electrical resonance effect occurs, which leads to a voltage peak occurring in a line voltage level (101).
