The invention relates to a device for the inductive transfer of electric energy from a stationary unit that has at least two similar primary inductances (1-4) to a vehicle (5) standing adjacent to said unit. The primary inductances (1-4) of the stationary unit can be supplied with electrical current independently of one another and the current supply can be individually activated or deactivated by a central control unit (12). Preferably, the device is equipped with a uniform two-dimensional arrangement (26-32, 27A-31A) of a plurality of primary inductances that are similar to one another and are in the form of a rectangular matrix (26-31). Either a dedicated output of a central current supply unit or a dedicated current supply unit (7-10) is assigned to each primary inductance. Preferably, the vehicle has several secondary inductances that are similar to one another, the dimensions and arrangement of said inductances being designed in such a way that several pairs of secondary and primary inductances overlap at any one time in at least one position of the vehicle (5A, 5B, 5C).
