The principle of the control device 101 of the embodiment to realize control in ac charging is specifically: when the electric vehicle 102 approaches the ac charging post 103, the second parts (corresponding to the three ports L3, N3, and PE3) corresponding to the three docking devices 1001A of the charging connector 1001 are in contact with and aligned with the first parts (corresponding to the three ports L2, N2, and PE2) corresponding to the three docking devices 1001A of the charging connector 2001 (the charging connector 1001 is in contact with and aligned with each other in fig. 1), and the ports (CC3, CP3) and the ports (CC2, CP2) of the connecting member 1002 are also communicated with each other. The charging requirement has been met, whereby, in the X direction, the electric vehicle touches the travel switch, which generates a first position detection signal and transmits the first position detection signal to the control device 101; in the Y direction, the electric vehicle is sensed by the proximity switch, the proximity switch generates a second position signal, and transmits the second position signal to the control device 101, and when the processor 1012 in the control device detects the first position detection signal and the second position detection signal at the same time, it determines that the second components (corresponding to the three ports L3, N3, and PE3) corresponding to the three docking devices 1001A of the charging connection unit 1001 are in good contact with the first components (corresponding to the three ports L2, N2, and PE2) corresponding to the three docking devices 1001A of the charging connection unit 1001. And then, the temperature between the three first components and the corresponding second components is checked and judged to be normal based on the temperature signal, the fault signal and the pressure detection signal, no fault exists, and when the plug is completely plugged into a socket of the electric vehicle, the charging requirement is met. When the charging requirement is met, the processor sends a connection confirmation execution instruction to the actuator, the actuator executes closing operation according to the connection confirmation execution instruction, accordingly, a charging connection confirmation signal is transmitted to one side of the alternating current charging pile, a connection confirmation line loop between the alternating current charging pile and the electric vehicle is connected, whether the communication state is normal or not is judged according to the charging connection confirmation signal, when the communication is normal, an alternating current contactor in the alternating current charging pile is closed, so that L1, N1, PE1 and L, N, PE are correspondingly connected, and the alternating current contactor serves as a charging switch to connect a charging loop between the electric vehicle and the charging pile so as to start charging.

The L1 and N1 power lines in the ac charging post are led out from the ac input (L, N), and power is supplied to the control device 101 by the dc-to-dc control power supply.

Thus, the position detection signal 1014 includes a first position detection signal and a second position detection signal. The data receiving port 1011 of the control device 101 receives the position detection signal 1014. The first position detection signal indicates that electrical conduction between the first part 1001a and the second part 1001b of the docking apparatus 011, respectively, in the X direction is normal. The second position detection signal indicates that electrical conduction between the first member 1001a and the second member 1001b of the docking device 1001, respectively, in the Y direction is normal. Thus, the position detection signal 1014 indicates that the electrical connection between the first member and the second member of the docking device is normal, in other words, the position detection signal 1014 indicates that the first member and the second member are in normal contact, and the charging condition is satisfied.

In this case, a travel switch and a proximity switch may be provided at the position of the connection member 1002 for detecting the contact state of the first member and the second member of the docking apparatus of the connection member 1002 and generating a corresponding first position detection signal and second position detection signal. Thus, the position detection signal 1014 includes a first position detection signal and a second position detection signal. The data receiving port 1011 of the control device 101 receives the position detection signal 1014. The position detection signal 1014 indicates that the electrical conduction between the first and second parts of the docking apparatus of the connection unit is normal. In this way, it is also indicated that the electrical conduction between the first and second parts of the docking device is normal. In other words, the position detection signal 1014 indicates that the first and second members of the docking device of the connection unit are in normal contact, and also indicates that the first and second members of the docking device of the charging connection unit are in normal contact, and the charging condition is satisfied.

In further embodiments, the charging system 10, includes a first detection switch, a second detection switch, and a third detection switch; for detecting the contact state in the X direction, the contact state in the Y direction, and the contact state in the Z direction of the first part 1001A and the second part 1001b of the docking device 1001A, respectively, and generating a first position detection signal, a second position detection signal, and a third position detection signal, respectively, correspondingly. Thus, the position detection signal 1014 includes a first position detection signal, a second position detection signal, and a third position detection signal. The data receiving port 1011 of the control device 101 receives the position detection signal 1014. The position detection signal 1014 indicates that the electrical conduction between the first and second parts of the docking device is normal, i.e., the contact is normal, and a charging condition is present.

The travel switch is also called a limit switch, when the electric vehicle approaches to the charging pile, the first part and the second part approach to each other and touch, and after the electric vehicle approaches to and touches the travel switch, the connecting rod of the travel switch drives the contact of the switch to cause the disconnection of the closed contact or the closing of the opened contact.
