Abstract
A method for a contactless transmission of electrical energy includes providing a leaf fastened to a wall. The leaf is hingedly mounted about a hinge axis. Providing a hinge plate pin. Providing a primary power coil fastened to the wall. Providing a secondary power coil fastened to the leaf. The primary power coil and the secondary power coil are in an inductive operative connection with each another via the hinge plate pin. Detecting an actual secondary power voltage induced in the secondary power coil. Comparing the actual secondary power voltage with a setpoint value of the secondary power voltage. Influencing a primary power applied to the primary power coil based on the comparison of the setpoint value and the actual secondary power voltage. Detecting the primary power required to achieve the setpoint value of the secondary power voltage. Triggering a signal when a predetermined primary power is exceeded.
