FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering. According to invention electronic device includes energy receiving facility to wirelessly receive energy from power supply device, detector to detect whether electronic device is in predetermined condition, load device, on which energy is supplied from energy receiving facility, and control facility configured to perform control so, that second energy is supplied from energy receiving facility to load facility, if detection device detects that electronic device is in predetermined condition, and first energy is supplied from energy receiving facility to load facility, wherein second energy is smaller than first energy, and said control device is also configured to perform control so, that first energy was supplied from energy reception facility to load facility, if the detection device detects, that electronic device is in condition different from predetermined condition, and energy supplied from power supply device, reduced to energy preset or smaller value.
EFFECT: technical result consists in termination or reducing of energy supply supplied from power supply device to electronic device, when it enters predetermined condition.
