Abstract:
1. A device for inductive transmission of electrical energy from a charging station to a vehicle, the device comprising: at least two primary inductors of a same type, each of the primary inductors electrically connected to a current supply unit such that each primary inductor has its own power supply for producing an electrical output; voltage-measuring devices, each current supply unit having a voltage-measuring device integrated therein; a controller in electrical communication with the current supply units; and signal leads, each current supply unit having a signal lead running to the controller; wherein the voltage-measuring devices measure voltage induced by presence of a secondary inductor producing a magnetic field at each primary inductor and emit measurement signals through the signal leads to the controller, each of the measurement signals indicating an induced voltage measured at each primary inductor; and wherein electrical current is supplied to each primary inductor individually through a switch activated or deactivated by the controller to control the electrical current supplied to each primary inductor based upon distribution of induced voltages measured at each of the primary inductors.
