VEHICLE CHARGING SYSTEM FOR CHARGING AN ENERGY STORE ARRANGED IN A VEHICLE

A system for charging an energy store in a vehicle and a method for operating the system, wherein the system includes a first transmission unit having a primary coil, arranged outside the vehicle in a stationary manner, and a second transmission unit having a secondary coil, arranged in the vehicle, wherein energy is transmitted via inductive energy transmission from the primary coil to the secondary coil to charge the energy store. The second transmission unit has a signal generator for generating and coupling signals into the secondary coil for transmission via the secondary coil, and the first transmission unit has an evaluation unit, a first auxiliary coil, and a second auxiliary coil, wherein the evaluation unit is designed to ascertain a magnetic coupling and/or a relative position between the first transmission unit and the second transmission unit based on the signals received by the primary coil and the auxiliary coils.
