The invention relates to a vehicle charging system for charging an energy storage arranged in a vehicle F and to a method for operating said vehicle charging system. The vehicle charging system according to the invention comprises a first transmission unit GPM (101), which has a primary coil (103) with a coil axis SPAP and is arranged outside the vehicle in a stationary manner in particular, and a second transmission unit CPM (102), which has a secondary coil (104) with a coil axis SPAS and is arranged in the vehicle F, wherein energy is transmitted by means of inductive energy transmission from the primary coil (103) to the secondary coil (104) in order to charge the energy storage. The vehicle charging system is characterized in that the second transmission unit CPM (102) has a signal generator SG (105) for generating signals SIGSG, said signal generator coupling the signals SIGSG into the secondary coil (104) in order to transmit said signals by means of the secondary coil, and the first transmission unit GPM (101) has an evaluation unit (106) and at least one first auxiliary coil (107a) with a coil axis SPAH1 and a second auxiliary coil (107b) with a coil axis SPAH2, said evaluation unit (106) being designed to acquire magnetic coupling kmag and/or the relative position delta POS between the first transmission unit GPM (101) and the second transmission unit CPM (102) on the basis of the signals SIGSG received by the primary coil (103) and the auxiliary coils (107a,b).

    本发明涉及一种用于对布置在交通工具F中的能量存储器进行充电的交通工具充电系统以及一种用于运行这种交通工具充电系统的方法。根据本发明的交通工具充电系统包括:第一传递单元GPM(101),其包括具有线圈轴SPAP的初级线圈(103)并且尤其是被固定不动地布置在交通工具之外;以及第二传递单元CPM(102),其包括具有线圈轴SPAS的次级线圈(104)并且被布置在交通工具F中,其中,用于对能量存储器进行充电的能量传递通过从初级线圈(103)至次级线圈(104)的感应式能量传递来进行。该交通工具充电系统的特征在于,第二传递单元CPM(102)具有用于产生信号SIGSG的信号发生器SG(105),信号发生器将信号SIGSG为了通过次级线圈(104)发出该信号而耦入到次级线圈中,以及第一传递单元GPM(101)具有评估单元(106)和至少一个具有线圈轴SPAH1的第一辅助线圈(107a)和至少一个具有线圈轴SPAH2的第二辅助线圈(107b),其中,评估单元(106)被设置用于,基于由初级线圈(103)和辅助线圈(107a、b)接收的信号SIGSG来获知第一传递单元GPM(101)和第二传递单元CPM(102)之间的磁性耦接kmag和/或相对位置ΔPOS。
