Embodiment Construction

[0037] exist figure 2 In , a schematic diagram for explaining the method according to the invention is shown. In this case, the current is conducted by a pole transformer 10 into a fuse box 12 in a building 14 . The fuse box 12 comprises three output connections V1 , V2 , V3 on lines VL1 , VL2 , VL3 , at which the three electrical phases L1 , L2 , L3 of the three-phase alternating current are supplied. In the figure, the electrical phase L1 is provided at the connection V1, that is to say in the line VL1, the electrical phase L2 is provided at the connection V2, that is to say in the line VL2, and at the connection V3, that is to say in the line VL3 The electrical phase L3 is provided on.

[0038] The output connections V1 to V3 are connected to the input connections E1 , E2 , E3 of the junction box 16 . The junction box 16 has, for example, two sockets K1 , K2 , wherein the first socket K1 includes connections K11 , K12 , K13 and the second socket K2 includes connections ...

Abstract

The invention relates to a method for operating a vehicle charging apparatus (22) for charging a vehicle battery (24). A particular line (VL1; VL2; VL3) on the decoupling point side is initially assigned to the first line (FL1; FL2; FL3) on the charging apparatus side by changing the charging current of a particular line (FL1; FL2; FL3) on the charging apparatus side and evaluating the line (VL1;VL2; VL3) on the decoupling point side in which a change can likewise be determined. This process is repeated for at least one second line (FL1; FL2; FL3) on the charging apparatus side.

Description

technical field [0001] The invention relates to a method for operating a vehicle charging device for charging a vehicle battery. Furthermore, the invention relates to a vehicle charging device for charging a vehicle battery, the vehicle charging device comprising: a communication device designed to communicate with a sensor device of a three-phase electrical output coupling point; for delivering energy for charging the vehicle battery The first, second and third electrical connectors on the side of the charging device; the output connector for connecting to the vehicle battery; and a control device for controlling the charging of the vehicle battery, wherein the control device is designed to, by means of the communication device, connect the At the output of the coupling point, the current current values ​​of the current intensities of the respective currents flowing in the first, second and third electrical lines on the coupling point side are read into the vehicle charging d...
