[0038] See also Figure 1, which shows a schematic diagram of the structure of a charging control device in one embodiment of the present invention. Figure 1 As shown, the two sides of the charging control device 1 described in the present invention are respectively connected to the device to be charged 2 and the charging pile 3. The charging control device 1 includes: a charging port 11, a communication port 12, a main control unit 13, an execution unit 14 and a power supply unit 15.

[0039] One end of the charging port 11 is connected to the device charging port of the device to be charged 2, and the other end is connected to the contactor of the charging pile 3, so as to realize contact connection of the charging circuit between the device to be charged 2 and the charging control device 1.

[0040] The communication port 12 is connected to the device communication port of the device to be charged 2 to achieve contact connection of the communication circuit between the device to be charged 2 and the charging control device 1 .

[0041] The main control unit 13 is used to determine whether the contact state of the communication port 12 is normal, so as to generate a communication execution instruction when the communication port 12 is electrically connected.

[0042] The execution unit 14 is connected to the main control unit 13 and the communication port 12 respectively, and is used to receive the communication execution instruction sent by the main control unit 13, and to conduct the communication circuit between the communication port 12 and the charging pile 3 according to the communication execution instruction so that the charging pile 3 can start charging when the communication is confirmed to be normal.

[0043] The power supply unit 15 is connected to the main control unit 13 and the execution unit 14 .

[0044] In one embodiment, the communication port is a contact-type mechanical port, enabling signal transmission between the charging control device and the device to be charged via contact. Preferably, the contact-type mechanical port can be a copper busbar, whereby the device communication port of the device to be charged also uses a copper busbar, with communication being achieved through contact between the copper busbar of the device to be charged and the copper busbar of the charging control device.

[0045] Furthermore, the copper busbar uses the same type of copper busbar as the charging port and the device charging port, so that when the charging copper busbar is aligned and in normal contact, the copper busbar used for communication is also aligned and in normal contact.

[0046] See also Figure 2 , which is a schematic diagram showing the detection principle of the charging control device of the present invention in one embodiment. Figure 2 As shown, the charging control device further includes: a detection unit 16.

[0047] The detection unit 16 is connected to the main control unit 13 and is used to generate a detection signal when the device communication port contacts the communication port 12; the detection signal is used to indicate that the electrical conduction between the communication port and the device communication port is normal.

[0048] In one embodiment, the power supply unit includes a first power supply unit and a second power supply unit.

[0049] The first power supply unit is connected to the detection unit and supplies power to the detection unit.

[0050] The second power supply unit is connected to the main control unit and the execution unit, and supplies power to the main control unit and the execution unit.

[0051] See also Figure 3 , which shows the AC charging control principle diagram of the charging control device of the present invention in one embodiment. Figure 3 As shown, the charging ports (L3 port, N3 port and PE3 port) and communication ports (first charging connection confirmation port, control confirmation port) of the charging control device are fixed on the fixed side of the flexible charging device. The mobile side of the flexible charging device of the device to be charged approaches and contacts the fixed side of the flexible charging device, thereby aligning with the charging port and communication port of the charging control device respectively to achieve normal contact.

[0052] In one embodiment, the communication port includes a first charging connection confirmation port and a control confirmation port.

[0053] The execution unit is used to execute the on-off operation between the first charging connection confirmation port and the charging pile, and to execute the on-off operation between the control confirmation port and the charging pile.

[0054] In one embodiment, the detection unit includes a travel switch and a proximity switch.

[0055] Specifically, the travel switch is used to detect the contact state in the X direction, and the proximity switch is used to detect the contact state in the Y direction.

[0056] The main control unit is connected to the travel switch and the proximity switch respectively, and is used to receive detection signals from the travel switch and the proximity switch, namely, detection signal 1 and detection signal 2.

[0057] like Figure 3As shown, the implementation principle of the charging control device of the present invention in AC charging is specifically as follows: when the device to be charged contacts the charging control device, the device charging port (L4 port, N4 port and PE4 port) contacts and aligns with the charging port (L3 port, N3 port and PE3 port), and the first charging connection confirmation port contacts and aligns with the control confirmation port, thereby knowing that the device to be charged is close to the charging control device and has reached the preset charging distance, meeting the charging requirements. Therefore, in the X direction, the device to be charged touches the limit switch, the limit switch generates a detection signal 1, and transmits the detection signal 1 to the main control unit; in the Y direction, the device to be charged is sensed by the proximity switch, the proximity switch generates a detection signal 2, and transmits the detection signal 2 to the main control unit. In the unit, when the main control unit detects detection signal 1 and detection signal 2 at the same time, it sends a communication execution instruction to the execution unit, and the execution unit performs a closing operation according to the communication execution instruction. In this way, the charging connection confirmation signal and the control confirmation signal are transmitted from the fixed side of the flexible charging device to the charging pile side, and the communication circuit between the charging pile and the device to be charged is connected. The communication status is determined to be normal based on the charging connection confirmation signal and the control confirmation signal. When the communication is normal, the AC contactor in the charging pile is closed, so that L2, N2, PE2 are connected to L, N, PE correspondingly, and L3, N3, PE3 are connected to L2, N2, PE2 correspondingly. The AC contactor acts as a charging switch to connect the charging circuit between the device to be charged and the charging pile to start charging.

[0058] Furthermore, the execution unit is a relay including a two-way switch. The execution unit executes the closing operation of the relay according to the communication execution instruction. In this way, the charging connection confirmation signal and the control confirmation signal are both transmitted from the fixed side of the flexible charging device to the charging pile side, and the communication circuit between the charging pile and the device to be charged is connected.

[0059] Furthermore, the L1 and N1 power lines in the AC charging pile are led out from the AC input (L, N), and power is supplied to the detection unit through the first power supply unit (i.e., AC to DC control power supply), the output voltage of the first power supply unit is led out, and power is supplied to the main control unit and the execution unit through the second power supply unit (i.e., DC to DC control power supply).

[0060] It should be noted that both the travel switch and the proximity switch can realize the function of detecting the contact status of the communication port. The travel switch is also called a limit switch. When the device to be charged approaches and touches the travel switch, the connecting rod of the travel switch drives the contacts of the switch to cause the closed contacts to disconnect or the open contacts to close. The proximity switch is also called a contactless travel switch, which can realize the travel control and limit protection functions. In the present invention, the travel switch and the proximity switch can be used interchangeably. For the proximity switch, in actual application, the installation position of the proximity switch can be embedded in the fixed side of the flexible charging device within a suitable distance range to ensure that when the sensing position of the device to be charged is close to the proximity switch, the charging port and the communication port just achieve stable contact.

[0061] See also Figure 4 , which shows a DC charging control principle diagram of a charging control device of the present invention in one embodiment. Figure 4 As shown, the charging ports (D+ port, D- port and PE port) and communication ports (CC1 port, CAN+ port, CAN- port, A+ port, A- port) of the charging control device are fixed on the fixed side of the flexible charging device, and the mobile side of the flexible charging device is provided on the device to be charged. The mobile side of the flexible charging device is provided with ports corresponding to the fixed side of the flexible charging device, namely, the device charging port (D+ port, D- port and PE port) and the device communication port (CC1 port, CAN+ port, CAN- port, A+ port, A- port). When the mobile side of the flexible charging device of the device to be charged approaches and contacts the fixed side of the flexible charging device, it is aligned with the charging port and communication port of the charging control device respectively to achieve normal contact.

[0062] In one embodiment, the communication port includes a second charging connection confirmation port (CC1 port), a first communication port (CAN+ port), a second communication port (CAN- port), an auxiliary power positive port (A+ port) and an auxiliary power negative port (A- port).

[0063] The execution unit is used to perform on-off operations between the second charging connection confirmation port (CC1 port), the first communication port (CAN+ port), the second communication port (CAN- port), the auxiliary power positive port (A+ port) and the auxiliary power negative port (A- port) and the charging pile.

[0064] In one embodiment, the detection unit includes a first detection switch (detection switch 1), a second detection switch (detection switch 2), and a third detection switch (detection switch 3); the first detection switch (detection switch 1) is used to detect the contact state in the X direction, the second detection switch (detection switch 2) is used to detect the contact state in the Y direction, and the third detection switch (detection switch 3) is used to detect the contact state in the Z direction.

[0065] The main control unit is connected to the first detection switch (detection switch 1), the second detection switch (detection switch 2) and the third detection switch (detection switch 3) respectively, and is used to receive detection signals from the first detection switch (detection switch 1), the second detection switch (detection switch 2) and the third detection switch (detection switch 3).

[0066] like Figure 4 As shown, the implementation principle of the charging control device of the present invention in DC charging is specifically as follows: when the device to be charged contacts the charging control device, the charging ports (DC+ port, DC- port, and PE port) contact and align, and the second charging connection confirmation port (CC1 port) and the first communication port (CAN+ port), the second communication port (CAN- port), the auxiliary power supply positive port (A+ port), and the auxiliary power supply negative port (A- port) contact and align, thereby knowing that the device to be charged is close to the charging control device and has reached the preset charging distance, meeting the charging requirements. Therefore, in the X direction, the device to be charged contacts the detection switch 1 to generate a detection signal 1, and the detection signal 1 is transmitted to the main control unit; in the Y direction, the device to be charged contacts the detection switch 2 to generate a detection signal 2. And transmit the detection signal 2 to the main control unit; in the Z direction, the device to be charged touches the detection switch 3 to generate a detection signal 3, and transmits the detection signal 3 to the main control unit; when the main control unit detects the detection signal 1, the detection signal 2 and the detection signal 3 at the same time, it sends a communication execution instruction to the execution unit, and the execution unit performs a closing operation according to the communication execution instruction. In this way, the charging connection confirmation signal, the communication signal and the auxiliary power supply signal are transmitted from the fixed side of the flexible charging device to the side of the charging pile, and the communication circuit between the charging pile and the device to be charged is connected, and the communication status is determined to be normal based on the charging connection confirmation signal and the communication signal. When the communication is normal, the DC contactor in the charging pile is closed. The DC contactor acts as a charging switch to connect the charging circuit between the device to be charged and the charging pile to start charging.

[0067] Specifically, the charging connection confirmation signal CC1, the communication signal CAN+ and the communication signal CAN- are transmitted to the DC charging pile controller to determine whether the communication status is normal. When the communication status is normal, on the one hand, the DC charging pile controller controls the DC contactor to close, so that the charging circuit between the device to be charged and the DC charging pile is connected; on the other hand, the DC charging pile controls the auxiliary power supply relay to close, so that the auxiliary power supply circuit between the switching power supply and the device to be charged is connected. In this way, the auxiliary power supply positive signal A+ and the auxiliary power supply negative signal A- generated by the switching power supply are transmitted to the device to be charged through the auxiliary power supply relay. In addition, the DC charging pile also includes a molded case circuit breaker, which is used to control the on and off between the DC charging pile and the input AC power. Then, after the molded case circuit breaker is turned on, it is divided into three paths: the first path converts the AC power into DC power used in the charging circuit through the DC module; the second path converts the AC power into an auxiliary power signal through the switching power supply; the third path generates the power supply for the detection unit, the main control unit and the execution unit through the AC to DC control power supply, that is, the U1 and N1 power lines in the DC charging pile are led out, and the detection unit is powered through the first power supply unit (that is, the AC to DC control power supply), the output voltage of the first power supply unit is led out, and the main control unit and the execution unit are powered through the second power supply unit (that is, the DC to DC control power supply).

[0068] Furthermore, the execution unit is a relay with a five-way switch. The execution unit closes the relay according to the communication execution instruction. As a result, the charging connection confirmation signal CC1, the communication signal CAN+, and the communication signal CAN- are transmitted from the fixed side of the flexible charging device to the charging pile, completing the communication circuit between the charging pile and the device to be charged. The auxiliary power supply positive signal A+ and the auxiliary power supply negative signal A- are transmitted from the charging pile to the fixed side of the flexible charging device, completing the auxiliary power supply circuit between the charging pile and the device to be charged.

[0069] It should be noted that the detection switches 1 , 2 and 3 may be travel switches, proximity switches, or other distance sensing devices other than travel switches and proximity switches.

[0070] See also Figure 5 , which is a flow chart showing the principle of the charging control method of the present invention in one embodiment. Figure 5 As shown, the charging control method specifically includes the following steps:

[0071] S51, detecting the contact status of the communication port.

[0072] In one embodiment, step S51 is performed by a detection unit, the detection unit including a first detection switch, a second detection switch, and a third detection switch; the first detection switch is used to detect a contact state in an X direction, the second detection switch is used to detect a contact state in a Y direction, and the third detection switch is used to detect a contact state in a Z direction; the step of determining whether the contact state of the communication port is normal so as to generate a communication execution instruction when the communication port is electrically conductive includes: generating the communication execution instruction when detection signals of the first detection switch, the second detection switch, and the third detection switch are simultaneously obtained.

[0073] In another embodiment, step S51 is performed by a detection unit, and the detection unit includes a travel switch and a proximity switch; the travel switch is used to detect the contact state in the X direction, and the proximity switch is used to detect the contact state in the Y direction; the step of determining whether the contact state of the charging port and the communication port is normal and generating a communication execution instruction when the contact state of the charging port and the communication port are both normal includes: generating the communication execution instruction when the detection signals of the travel switch and the proximity switch are simultaneously obtained.

All solutions implemented by adding, reducing, or replacing steps in the prior art based on the principles of the present invention are included in the protection scope of the present invention.

[0078] In summary, the charging control device and charging control method of the present invention detect the contact status of the communication port through the main control unit, and when the contact status is electrically conductive, the control execution unit conducts the communication circuit between the communication port and the charging pile, thereby realizing the detection of the communication status, so as to start charging when the communication status is normal. Thus, the double insurance of contact status and communication status detection is realized in the communication circuit detection of the charging control process, which can guarantee the reliability and safety of charging to the greatest extent. Furthermore, the communication port of the present invention and the device communication port of the device to be charged are connected by a contact mechanical port, which has higher communication reliability than the non-contact communication of the existing communication coil.
