[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0032] In a vehicle charging system, a charging connection confirmation resistor (Connection Confirm Resistor, abbreviated as CC resistor) is a key component used to ensure the correct connection between the charging gun and the vehicle charging interface, and is usually located between the charging gun and the vehicle charging interface. The vehicle control device determines the connection state of the charging gun and the vehicle socket, such as fully connected, semi-connected, or not connected, by detecting the resistance value of the CC resistor, so as to ensure the safety of the charging process. Only when the resistance value of the CC resistor is within the specified range and other conditions are met, the vehicle will allow charging to start.

[0033] The resistance value of the CC resistor is different, and the overcurrent capacity of the corresponding charging cable is also different. By detecting the resistance value of the CC resistor, the vehicle can determine the rated current of the charging cable, and then determine the magnitude of the charging current to ensure the safety and stability of the charging process and prevent overload.

[0034] In the related art, when a conductive foreign object enters the vehicle charging socket or water seeps in humid weather (that is, the environmental false trigger circuit causes the circuit resistance value to change), a conduction loop can be formed in the charging socket. Even if the charging gun 700 or the discharge gun is not inserted, the charging socket will be conducted, resulting in the resistance value of the CC resistor 200 being a resistance value that can wake up the vehicle control device, and then causing the vehicle control device to misjudge that the charging gun 700 or the discharge gun is connected, and then mis-sending the gun connection message, which will affect the normal driving of the vehicle and there are safety hazards.

[0035] In view of the above technical problems, according to the first aspect of the present application, referring to Figure 1 a charge and discharge detection system 10 is provided, including: a trigger mechanism 100.

[0036] The trigger mechanism 100 in the embodiments of the present application is configured to be able to trigger the charge and discharge detection system 10 to execute a preset function when the charging gun 700 is combined with the charging dock 600.

[0037] Through the above technical solution, when the charging gun 700 is combined with the charging base 600, the triggering mechanism 100 triggers the charge and discharge detection system 10 to execute a preset function. In this way, the premise for the charge and discharge detection system 10 to execute the preset function is defined by the triggering mechanism 100, so as to improve the usage accuracy of the charge and discharge detection system 10. After the charge and discharge detection system 10 executes the preset function, it is then determined whether to send a gun connection signal, effectively avoiding the situation of accidentally waking up the charge and discharge detection system 10 to execute the preset function and not affecting the normal driving of the vehicle.

[0038] In some embodiments, the preset function includes at least one of the following: The CC resistor 200 detection loop A in the charging gun 700 is conducted; Perform the detection operation of the CC resistor 200 according to the wake-up voltage of the detection system 10; Determine the resistance value of the CC resistor 200 in the charging gun 700.

[0039] Exemplarily, the preset function in the embodiments of the present application includes the conduction of the CC resistor detection loop A in the charging gun 700. In this way, when the charging gun 700 is combined with the charging base 600, the detection system 10 can execute the confirmation that the detection loop A is conducted.

[0040] Exemplarily, the preset function in the embodiments of the present application includes performing the detection operation of the CC resistor 200 according to the wake-up voltage of the detection system 10. That is, after the detection loop A is conducted, the voltage change at the preset point can be used as the wake-up voltage to wake up the detection system 10 to perform the detection operation of the CC resistor. Exemplarily, the wake-up voltage can be the first voltage value measured at the preset point. After determining that there is a voltage change, the resistance value of the CC resistor is calculated according to the subsequent voltage values at the preset point. It is also possible to directly start the calculation of the CC resistor with the first voltage value measured at the preset point, which can be set according to the actual application scenario, and the embodiments of the present application do not limit this.

[0041] Exemplarily, the preset function in the embodiments of the present application can also include determining the resistance value of the CC resistor 200 in the charging gun 700, so as to determine whether the resistance value of the CC resistor 200 in the charging gun 700 is the resistance value of the resistor that can enable the charge and discharge detection system 10 to send a gun connection signal.

[0042] The charge and discharge detection system 10 in the embodiments of the present application does not directly perform the operation of determining the resistance value of the CC resistor 200 in the charging gun 700. When the charging gun 700 is combined with the charging base 600, the charging detection system 10 is triggered (i.e., woken up) by the triggering mechanism 100, so that the charging detection system 10 can perform the operation of determining the resistance value of the CC resistor 200 in the charging gun 700.

[0043] Exemplarily, after determining the resistance value of the CC resistor 200 in the charging gun 700, if the resistance value of the CC resistor 200 in the charging gun 700 is within a preset range, the charge and discharge detection system 10 can send a gun connection signal, improving the accuracy of the charging detection system 10.

[0044] If the resistance value of the CC resistor 200 in the charging gun 700 is not within the preset range, the charge and discharge detection system 10 does not send a gun connection signal and does not perform the operation of entering charge and discharge, which can prevent the charge and discharge detection system 10 from mistakenly sending a gun connection signal, saving the startup battery power and reducing energy consumption.

[0045] In some embodiments, referring to Figure 1 , the detection system 10 further includes: a voltage detection module 900 and a control module 500.

[0046] The voltage detection module 900 in the embodiments of the present application is used to detect the voltage value at a preset point, and the control module 500 is used to determine the resistance value of the CC resistor 200 according to the voltage value at the preset point; wherein, the preset point is set on the charging base 600.

[0047] By setting the voltage detection module 900 to detect the voltage value at the preset point on the charging base 600, and then using the control module 500 to determine the resistance value of the CC resistor 200 according to the voltage value at the preset point, the resistance value of the CC resistor 200 in the charging gun 700 can be determined in this way, and by setting the preset point on the charging base 600, the voltage can be detected nearby, improving the accuracy of determining the resistance value of the CC resistor 200.

[0048] It should be noted that the control module 500 in the embodiments of the present application can reuse the control module 500 on the vehicle for controlling vehicle braking, driving, window lifting, etc. Exemplarily, the control module 500 in the embodiments of the present application can be a vehicle controller or a vehicle domain controller.

[0049] In the embodiments of the present application, exemplarily, referring to Figure 3 , the preset point can be set to one, defined as the first preset point 300, and the first preset point 300 is located between the trigger mechanism 100 and the control module 500.

[0050] Exemplarily, referring to Figure 5, the preset points can be set to two, defined as the first preset point 300 and the second preset point 400. The first preset point 300 is located between the detection circuit A and the control module 500, and the triggering mechanism 100 is located in the first loop L1 between the control module 500 and the second preset point 400. Moreover, a second loop L2 is provided between the second preset point 400 and the control module 500. The voltage detection module 900 preferentially detects the voltage of the first preset point 300. After detecting the voltage of the first preset point 300, it then detects the voltage of the second preset point 400, and further confirms the resistance value of the CC resistor 200 through the voltage of the first preset point 300.

[0051] In some embodiments, the triggering mechanism 100 includes at least one of the following: a limit switch 110, a travel switch, a push switch, and a trigger sensor 120.

[0052] In some embodiments, refer to Figure 2 and Figure 3 , the limit switch 110 includes: a contact 111 and a push rod 112.

[0053] In the embodiments of the present application, the contact 111 is located on the charging base 600, and the push rod 112 is located on the charging gun 700.

[0054] When the push rod 112 presses the contact 111, it is determined that the charging gun 700 is combined with the charging base 600.

[0055] By setting the way that the push rod 112 presses the contact 111, it is determined that the charging gun 700 is combined with the charging base 600. In this way, mechanical linkage triggering can be achieved, improving the reliability of triggering and further improving the detection accuracy of the detection system 10.

[0056] Exemplarily, refer to Figure 2 , a mechanical lock is provided on the charging base 600, and the contact 111 is arranged on one side wall surface of the mechanical lock.

[0057] In the case of charging or discharging, the push rod 112 of the charging gun 700 can be inserted into the mechanical lock and press the contact 111 from left to right, so that the internal contacts of the switch can be closed. In this way, when the charging base 600 is combined with the charging gun 700, the control module 500 can be triggered by the triggering mechanism 100 to execute the function of determining the resistance value of the CC resistor 200 in the charging gun 700.

[0058] In the case of the end of charging or discharging, the combination between the charging gun 700 and the charging base 600 is disconnected. In this way, the push rod 112 of the charging gun 700 can be withdrawn from the mechanical lock to separate the push rod 112 from the contact 111. In this case, the charging and discharging are ended.

[0059] Exemplarily, the shape of the contact 111 includes at least one of a hemispherical shape, a conical shape, a frustum of a cone shape, an ellipsoidal shape, and a cylindrical shape.

[0060] In some embodiments, referring to Figure 4 , the trigger sensor 120 includes: a first trigger sensor 121 and a second trigger sensor 122.

[0061] In the embodiments of the present application, the first trigger sensor 121 is disposed on the charging gun 700, and the second trigger sensor 122 is disposed on the charging base 600.

[0062] Wherein, the first trigger sensor 121 and the second trigger sensor 122 are electrically connected to determine the combination of the charging gun 700 and the charging base 600 when the signals match.

[0063] In the embodiments of the present application, through the electrical connection between the first trigger sensor 121 and the second trigger sensor 122, the signal matching between the two trigger sensors 120 is realized, and then it can be determined that the charging gun 700 is combined with the charging base 600. In this way, the interference of the environment can be avoided, and when the charging gun 700 is loosely connected to the vehicle charging base 600, the function of prohibiting driving when the gun is inserted can be effectively triggered, thereby avoiding the problem of the vehicle dragging and damaging the charging pile.

[0064] In some embodiments, the trigger sensor 120 includes at least one of the following: an infrared trigger sensor, an inductive trigger sensor, and a capacitive trigger sensor.

[0065] Exemplarily, when the trigger sensor 120 includes an infrared trigger sensor, a first infrared trigger sensor is disposed on the charging gun 700, and a second infrared trigger sensor is disposed on the charging base 600. The second infrared trigger sensor on the charging base 600 serves as the receiving end, and the first infrared trigger sensor on the charging gun 700 serves as the transmitting end. When the receiving end at the vehicle charging base 600 detects the signal emitted by the transmitting end on the charging gun 700, the vehicle control module 500 is woken up to detect the CC resistor 200.

[0066] Exemplarily, when the trigger sensor 120 includes an inductive trigger sensor, an inductive emission coil can be disposed on the charging gun 700 as the first trigger sensor 121, and an inductive receiving coil can be disposed on the charging base 600 as the second trigger sensor 122, where the inductive emission coil is used to emit a high-frequency electromagnetic field, and the inductive receiving coil is used to sense the change of the electromagnetic field.

[0067] In the embodiments of the present application, the magnetic coupling strength between the inductive emission coil and the inductive reception coil is used to determine whether the charging base 600 and the charging gun 700 are effectively connected (i.e., combined). That is, when the coupling strength increases, it indicates that the charging gun 700 is inserted into the charging base 600 and the two are effectively connected, and then the control module 500 will be awakened (i.e., triggered) to determine the resistance value of the CC resistor 200 in the charging gun 700; when the coupling strength does not change significantly, it indicates that the charging gun 700 and the charging base 600 are not effectively connected, and then the control module 500 will not be awakened (i.e., triggered) to determine the resistance value of the CC resistor 200 in the charging gun 700.

[0068] Exemplarily, when the trigger sensor 120 includes a capacitive trigger sensor, a transmitting electrode is provided on the charging gun 700 as the first trigger sensor 121, and a receiving electrode is provided on the charging base 600 as the second trigger sensor 122, where the transmitting electrode is used to generate an alternating electric field, and the receiving electrode is used to detect the change in the electric field.

[0069] In the embodiments of the present application, the capacitive coupling strength between the transmitting electrode and the receiving electrode is used to determine whether the charging base 600 and the charging gun 700 are effectively connected (i.e., combined). That is, when the coupling strength increases, the capacitance value increases, indicating that the charging gun 700 is inserted into the charging base 600 and the two are effectively connected, and then the control module 500 will be awakened (i.e., triggered) to determine the resistance value of the CC resistor 200 in the charging gun 700; when the coupling strength does not change significantly, the capacitance value does not change significantly, indicating that the charging gun 700 and the charging base 600 are not effectively connected, and then the control module 500 will not be awakened (i.e., triggered) to determine the resistance value of the CC resistor 200 in the charging gun 700.

[0070] In some embodiments, the control module 500 is further configured to control the charging gun 700 and the vehicle battery to perform an electric energy exchange operation when the resistance value of the CC resistor 200 satisfies a preset resistance value range.

[0071] Specifically, when the resistance value of the CC resistor 200 is within the preset range, it indicates that the connection between the charging gun 700 and the charging base 600 is reliable, and the charging gun 700 and the vehicle battery can be controlled to perform an electric energy exchange operation, that is, the charging and discharging of the vehicle battery can be realized.

[0072] Exemplarily, the discharge of the vehicle battery can release the electric energy of the vehicle battery into the power grid.

[0073] According to the second aspect of the present application, a charging detection method is provided. Refer to Figure 6 , the method includes: Step S010: When the charging gun is combined with the charging base, trigger the charging detection system to execute a preset function.

[0074] Through the above technical solution, when the charging gun is combined with the charging base, the charging detection system is triggered to execute a preset function, which limits the precondition for the charging detection system to execute the preset function, improves the accuracy of the use of the charge and discharge detection system, effectively reduces the number of times the charging detection system is woken up by mistake to execute the preset function, and avoids the situation where the charging detection system executes the preset function and then mistakenly sends a gun connection signal to affect the normal driving of the vehicle when the charging gun and the charging base are not combined.

[0075] In some embodiments, referring to Figure 7 , the method further includes: Step S001: When the triggering mechanism meets the preset conditions, determine that the charging gun is combined with the charging base.

[0076] It should be noted that in the embodiment of the present application, the confirmation that the charging gun and the charging base are combined in step S001 is executed before step S010, that is, only when it is determined that the charging gun and the charging base are combined, will step S010 be executed to trigger the charging detection system to execute the preset function.

[0077] In some embodiments, the triggering mechanism includes at least one of the following: a limit switch, a travel switch, a push switch, and a trigger sensor.

[0078] In the embodiment of the present application, the triggering mechanism may include a mechanical switch or an optical switch of the trigger sensor type, which can be selected according to actual needs and will not be elaborated here.

[0079] In some embodiments, the preset conditions include at least one of the following: If the triggering mechanism is a limit switch, the contact of the limit switch is applied with a first preset pressure; If the triggering mechanism is a travel switch, the travel switch meets the travel threshold; If the triggering mechanism is a push switch, the push switch is applied with a second preset pressure; If the triggering mechanism is a trigger sensor, the signal between the first trigger sensor on the charging gun and the second trigger sensor on the charging base matches.

[0080] Exemplarily, referring to Figure 2 and Figure 3 , the triggering mechanism includes a limit switch, and the contact of the limit switch is applied with a first preset pressure, that is, the push rod on the charging gun can apply the first preset pressure to the contact on the charging base.

[0081] Exemplarily, the triggering mechanism includes a travel switch. When the travel switch meets the travel threshold, that is, during the process of inserting the charging gun into the charging base, the push rod of the travel switch will be pressed and slide, and then the spring inside the switch can be compressed. When the displacement of the spring meets the travel threshold, it triggers the closure, indicating that the charging gun and the charging base are effectively connected. When the displacement of the spring does not meet the formation threshold, it triggers to remain open, indicating that the charging gun and the charging base have not established an effective connection.

[0082] Exemplarily, the triggering mechanism includes a push switch, and the push switch is applied with a second preset pressure, that is, the push rod on the charging gun can apply the second preset pressure to the push switch.

[0083] Exemplarily, the triggering mechanism includes a trigger sensor, and the signal between the first trigger sensor located on the charging gun and the second trigger sensor located on the charging base matches. The trigger sensor in the embodiments of the present application can be an infrared trigger sensor, an inductive trigger sensor, or a capacitive trigger sensor.

[0084] It should be noted that the descriptions of the self-operations of the infrared trigger sensor, the inductive trigger sensor, and the capacitive trigger sensor have been recorded above and will not be elaborated here.

[0085] In some embodiments, the preset function includes at least one of the following: The CC resistor detection circuit in the charging gun is turned on; Perform the detection operation of the CC resistor according to the wake-up voltage of the detection system; Determine the resistance value of the CC resistor in the charging gun.

[0086] By including determining the resistance value of the CC resistor in the charging gun in the preset function, when the charging gun is combined with the charging base, it is possible to confirm whether the charge and discharge operations need to be performed by confirming the resistance value of the CC resistor in the charging gun, which has high safety.

[0087] In some embodiments, referring to Figure 7 , the method further includes: Step S002: Detect the voltage value at the preset point.

[0088] Step S003: Determine the resistance value of the CC resistor according to the voltage value at the preset point.

[0089] Among them, the preset point is set on the charging base.

[0090] In step S002 of the embodiments of the present application, the voltage value at the preset point is detected, and in step S003, the resistance value of the CC resistor is determined according to the voltage value at the preset point, and whether normal charge and discharge can be performed is judged according to the determined resistance value of the CC resistor.

[0091] In some embodiments, referring toFigure 7 , the method further includes: Step S011: When the resistance value of the CC resistor satisfies a preset resistance range, control the charging gun and the vehicle battery to perform an electric energy exchange operation.

[0092] Specifically, in step S011, when the resistance value of the CC resistor satisfies the preset resistance range, control the charging gun and the vehicle battery to perform an electric energy exchange operation, that is, perform a charging and discharging operation between the two.

[0093] If the resistance value of the CC resistor does not satisfy the preset resistance range, the charging and discharging process will not be performed. That is, if the resistance value of the CC resistor does not satisfy the preset resistance range, even if the charging base and the charging gun are determined to be combined, the charging and discharging operation will not be performed.

[0094] In the embodiments of the present application, the resistance value of the CC resistor is the resistance value of the detection circuit. When the mechanical lock switch is not closed, the resistance value of the CC resistor in the detection circuit is R1 = Ra + Rb, and the voltage value at the preset point is U1 at this time. When the mechanical lock switch is closed, the resistance value of the CC resistor in the detection circuit is R2 = Rb, and the voltage value at the preset point is U2 at this time.

[0095] When the triggering mechanism meets the preset conditions, the mechanical lock switch will be closed simultaneously. In this case, the charge and discharge detection system will be awakened to execute the preset function, that is, the charge and discharge detection system will be awakened to determine the resistance value of the CC resistor in the charging gun. That is, the voltage detection module detects the voltage value at the preset point, and the control module determines the resistance value of the CC resistor according to the voltage value at the preset point.

[0096] Expanding, the voltage detection module detects that the voltage value at the preset point is U2, and then calculates the resistance value of the CC resistor as R2 according to the voltage value U2. This indicates that the resistance value of the CC resistor in the detection circuit meets the conditions of the preset resistance range, and the control module can send a gun connection signal and enter the charge and discharge process.

[0097] If the voltage detection module detects that the voltage value at the preset point is U1, it means that the resistance value of the CC resistor in the detection circuit is R1 = Ra + Rb. This indicates that the resistance value of the CC resistor in the detection circuit does not meet the conditions of the preset resistance range. In this case, the control module will not send a gun connection signal and will not enter the charge and discharge process, and the operator needs to re-plug the charging gun.

[0098] Reference Figure 3 , in the embodiments of the present application, there can be one preset point. In this case, the triggering mechanism is located between the preset point and the detection circuit, and will Figure 3The preset point therein is defined as the first preset point. When the triggering mechanism meets the preset conditions, it triggers the charging detection system to execute the preset function, that is, the voltage detection module detects the voltage value of the first preset point, and the control module determines the resistance value of the CC resistor according to the detected voltage value of the first preset point. If the resistance value of the CC resistor meets the preset range, the control module of the charge and discharge detection system sends a gun connection signal and enters the charge and discharge process. If the resistance value of the CC resistor does not meet the preset range, the control module of the charge and discharge detection system does not send a gun connection signal and does not enter the charge and discharge process.

[0099] To further improve the accuracy of the entire charging detection system, in some other embodiments, referring to Figure 5 , the number of preset points can be set to two, defined as the first preset point and the second preset point. The first preset point is located between the detection circuit and the control module, and the triggering mechanism is located in the first circuit between the control module and the second preset point, and there is also a second circuit between the second preset point and the control module. The voltage detection module preferentially detects the voltage of the first preset point. After detecting the voltage of the first preset point, it then detects the voltage of the second preset point. When the triggering mechanism meets the preset conditions, the voltage value of the second preset point is U3. When the triggering mechanism does not meet the preset conditions, the voltage value of the second preset point is U4.

[0100] The following is an explanation of the Figure 5 charge and discharge detection system solution in 1. If the detected voltage value of the second preset point is U3, it means that the triggering mechanism meets the preset conditions and can trigger the charging detection system to execute the preset function, that is, the control module determines the resistance value of the CC resistor according to the voltage of the first preset point. If it is R2 (mechanical lock switch closed), the control module of the charge and discharge detection system sends a gun connection signal and enters the charge and discharge process. This situation can be defined as a trusted state.

[0101] 2. If the detected voltage value of the second preset point is U3, it means that the triggering mechanism meets the preset conditions and can trigger the charging detection system to execute the preset function, that is, the control module determines the resistance value of the CC resistor according to the voltage of the first preset point 300. If it is not R2 but R1 (mechanical lock switch not closed), in this case, the control module of the charge and discharge detection system will send a gun connection signal but will not enter the charge and discharge process. This situation can be defined as a distrusted state.

[0102] 3. If the detected voltage value at the second preset point is U4, it indicates that the triggering mechanism does not meet the preset conditions. Even if the resistance value of the CC resistor is determined to be R2 based on the voltage at the first preset point (mechanical lock switch closed), in this case, the control module of the charge and discharge detection system will not send a gun connection signal and will not enter the charge and discharge process. This situation can be defined as a distrust state. In the distrust state, by re-plugging the charging gun, the triggering mechanism can be made to meet the preset conditions.

[0103] 4. If the detected voltage value at the second preset point is U4, it indicates that the triggering mechanism does not meet the preset conditions, and the resistance value of the CC resistor is determined to be R1 based on the voltage at the first preset point (mechanical lock switch not closed). In this case, the control module of the charge and discharge detection system does not send a gun connection signal and will not enter the charge and discharge process. This situation can be defined as a distrust state.

[0104] The charge and discharge detection system of the embodiment of the present application will send a gun connection signal and enter the charge and discharge process in the trust state.

[0105] In summary, in the embodiment of the present application, when the charging gun and the charging seat are combined, the control module is triggered by the triggering structure to execute the preset function, which can meet the vehicle AC charge and discharge in different scenarios. When the triggering mechanism of the vehicle-side charging seat is not closed, the charging detection system will not be awakened and perform the operation of the preset function; when the triggering mechanism is closed, the charging detection system will be awakened, and the control module will determine the resistance value of the CC resistor according to the voltage value detected by the voltage detection module. When the resistance value of the CC resistor meets the preset range, the control module sends a gun connection signal and enters the charge and discharge process. When the CC resistance value does not meet the preset range, the gun connection signal will not be sent to enter the AC charge and discharge process, and the charging gun or the discharge gun needs to be re-plugged to make a new judgment.

[0106] In the embodiment of the present application Figure 1 The detection system shown and Figure 8 The detection method shown can accurately identify whether the charging gun and the charging seat are combined, prevent the charging detection system from being accidentally awakened and accidentally trigger the gun connection signal to enter the charge and discharge process, and can effectively reduce the situation where the resistance value of the CC resistor changes due to foreign objects entering at the charging seat or water seeping in humid weather, reduce the probability of the charging detection system being accidentally awakened and accidentally sending the gun connection message, and reduce the risk of affecting the normal driving of the vehicle under certain working conditions, and can save the startup battery power and reduce the energy consumption.
