The output end of the second unidirectional conduction module 190 is electrically connected to the input end of the vehicle monitoring host 1100, and the output end of the vehicle monitoring host 1100 is electrically connected to the five-in-one controller 140.

[0042] In the embodiment of the present invention, when the vehicle is plugged into the charging gun 200, the vehicle controller 110 outputs a first control signal to the control end of the first switch module 120, so that the first switch module 120 is disconnected; the input end of the first unidirectional conduction module 150, the control end of the second switch module 180 and the input end of the second unidirectional conduction module 190 are all electrically connected to the output end of the charging gun 200; the first power signal output by the charging gun 200 is input to the battery management system 160 via the first unidirectional conduction module 150, and the battery management system 160 outputs a first control signal to the first battery current converter 170, so that the first battery current converter 170 works; the first power signal output by the charging gun 200 is also input to the control end of the second switch module 180, so that the second switch module 180 is turned on, and the first current output by the first battery current converter 170 is input to the five-in-one controller 140.

[0043] It should be noted that, in other embodiments, when the vehicle is not plugged into the charging gun 200 and the whole vehicle is in the ignition ON state and the high voltage is applied, each component is powered by the first power supply 130 .

[0044] In the solution of the embodiment of the present invention, when the vehicle is charging, the first power supply 130 and the charging gun 200 can both supply power to the vehicle monitoring host 1100 and the battery management system 160 through the first unidirectional conduction module 150 and the second unidirectional conduction module 190, and the first battery current converter 170 can supply power to the five-in-one controller 140 through the second switch module 180, so that the vehicle monitoring host 1100 can normally monitor the battery management system 160, the five-in-one controller 140 and the charging gun 200 when other parts of the vehicle are not powered on. In addition, the requirements of charging and charging monitoring with the vehicle turned off are guaranteed, and the safety of vehicle charging is guaranteed.

[0045] Figure 2 A schematic diagram of another charging monitoring system provided by an embodiment of the present invention. Optionally, based on the above embodiment, refer to Figure 2 The charging monitoring system also includes: a thermal management controller 1110 , a vehicle current converter 1120 , and a heat and cooling unit 1130 .

[0046] Continue to refer Figure 2 The output end of the thermal management controller 1110 is electrically connected to the input end of the five-in-one controller 140 , the output end of the five-in-one controller 140 is electrically connected to the input end of the vehicle current converter 1120 , and the output end of the vehicle current converter 1120 is electrically connected to the input end of the heating and cooling unit 1130 .

[0047] The vehicle current converter 1120 may include a vehicle DCDC converter.

[0048] It is understandable that if the charging gun 200 of the embodiment of the present invention is a fast charging gun, the thermal management controller 1110 needs to work when the vehicle is charged. In the embodiment of the present invention, when the vehicle is charged, the first power supply 130 and the charging gun 200 can both supply power to the vehicle monitoring host 1100 and the battery management system 160 through the first unidirectional conduction module 150 and the second unidirectional conduction module 190, and the first battery current converter 170 can supply power to the five-in-one controller 140 and the thermal management controller 1110 through the second switch module 180, so as to ensure that the vehicle monitoring host 1100 can normally monitor the battery management system 160, the five-in-one controller 140, the charging gun 200 and the thermal management controller 1110 when other components of the vehicle are not powered on. Among them, the five-in-one controller 140 detects the charging status signal output by the thermal management controller 1110, and when it detects that the battery needs to be cooled down, it controls the vehicle current converter 1120 to output current to power the heat and cold unit 1130. When the vehicle is plugged into the charging gun 200, the vehicle controller 110 outputs a first control signal to the control end of the first switch module 120, so that the first switch module 120 is disconnected, which can ensure that the vehicle is not on high voltage and does not have the conditions to work. However, the vehicle current converter 1120 can supply power to the heat and cool unit 1130, so that the heat and cool unit 1130 works to charge and cool the battery.

[0049] Optionally, based on the above embodiment, continue to refer to Figure 2 The output end of the first battery current converter 170 is also electrically connected to the input end of the second unidirectional conduction module 190 .

[0050] It can be understood that in order to solve the problem of one-way power supply for components, in the embodiment of the present invention, the output end of the first battery current converter 170 is also electrically connected to the input end of the second unidirectional conduction module 190, which can ensure that the first battery current converter 170 supplies power to the vehicle monitoring host 1100 during charging.

[0051] Optionally, based on the above embodiment, continue to refer to Figure 2 , the first unidirectional conduction module 150 includes a first diode 151, and the second unidirectional conduction module 190 includes a second diode 191. The anode of the first diode 151 is electrically connected to the output end of the first power source 130, and the cathode of the first diode 151 is electrically connected to the battery management system 160. In the embodiment of the present invention, when the vehicle is plugged into the charging gun 200, the anode of the first diode 151 is also electrically connected to the output end of the charging gun 200. The output end of the first power source 130 and the output end of the first battery current converter 170 are both electrically connected to the anode of the second diode 191; when the vehicle is plugged into the charging gun 200, the anode of the second diode 191 is also electrically connected to the output end of the charging gun 200.

[0052] A diode box may be additionally provided outside the first diode 151 and the second diode 191 .

[0053] Optionally, based on the above embodiment, continue to refer to Figure 2 , the first switch module 120 includes a first relay 121, and the second switch module 180 includes a second relay 181. The control end of the first relay 121 is electrically connected to the output end of the vehicle controller 110, the input end of the first relay 121 is electrically connected to the output end of the first power supply 130, and the output end of the first relay 121 is electrically connected to the five-in-one controller 140. The input end of the second relay 181 is electrically connected to the first battery current converter 170. When the vehicle is plugged into the charging gun 200, the control end of the second relay 181 is electrically connected to the output end of the charging gun 200, and the output end of the second relay 181 is electrically connected to the input end of the five-in-one controller 140.

[0054] It can be understood that in the embodiment of the present invention, the power supply current of the low-power components (such as the vehicle monitoring host 1100) is externally processed through the first diode 151 and the second diode 191. Since the heat dissipation of the first diode 151 and the second diode 191 cannot meet the power supply requirements of the larger power components (such as the five-in-one controller 140 and the thermal management controller 1110), the first relay 121 and the second relay 181 are used to externally process the power supply current of the larger power components, which can ensure the safety of the circuit.

[0055] Optionally, based on the above embodiment, the first relay 121 and the second relay 181 are both five-prong relays.

[0056] It should be noted that the control end of the five-claw relay includes an electromagnet and a coil, the output end of the five-claw relay includes a moving contact and an iron core, and the input end of the five-claw relay includes a fixed contact. The moving contact contacts or separates with the fixed contact under the action of the electromagnet to realize the opening and closing of the circuit. When the coil is energized, the electromagnet generates a magnetic field, attracts the iron core, causes the moving contact to contact with the fixed contact, and the circuit is turned on. When the coil is de-energized, the magnetic field of the electromagnet disappears, the iron core returns to its original position, the moving contact separates from the fixed contact, and the circuit is disconnected.

[0057] In the embodiment of the present invention, when the vehicle is charging, the first power source 130 and the charging gun 200 can both supply power to the vehicle monitoring host 1100 and the battery management system 160 through the first unidirectional conduction module 150 and the second unidirectional conduction module 190, and the first battery current converter 170 can supply power to the five-in-one controller 140 and the thermal management controller 1110 through the second switch module 180, so as to ensure that the vehicle monitoring host 1100 can normally monitor the battery management system 160, the five-in-one controller 140, the charging gun 200 and the thermal management controller 1110 when other components of the vehicle are not powered on. Among them, when the charging gun 200 is a fast charging charging gun, the five-in-one controller 140 detects the charging state signal output by the thermal management controller 1110, and when it detects that the battery needs to be cooled down, it controls the vehicle current converter 1120 to output current to supply power to the heat and cold unit 1130. When the vehicle is plugged into the charging gun 200, the vehicle controller 110 outputs the first control signal to the control end of the first switch module 120, so that the first switch module 120 is disconnected, which can ensure that the vehicle is not on high voltage and does not have the conditions for working, but the vehicle current converter 1120 can supply power to the heat and cold unit 1130 to charge and cool the battery. In order to solve the problem of one-way power supply for components, in the embodiment of the present invention, the output end of the first battery current converter 170 is also electrically connected to the input end of the second unidirectional conduction module 190, which can ensure that the first battery current converter 170 supplies power to the vehicle monitoring host 1100 during charging. The power supply current of low-power components (such as the vehicle monitoring host 1100) is externally processed through the first diode 151 and the second diode 191. Because the heat dissipation of the first diode 151 and the second diode 191 cannot meet the power supply requirements of higher-power components (such as the five-in-one controller 140 and the thermal management controller 1110), the first relay 121 and the second relay 181 are used to externally process the power supply current of the higher-power components, which can ensure the safety of the circuit.

[0058] Figure 3 Flow chart of a charging monitoring method provided by an embodiment of the present invention, the charging monitoring method is implemented by the charging monitoring system provided by the above embodiment, refer to Figure 3 , the charging monitoring method comprises:

[0059] S310, detecting the status of the charging gun.

[0060] Among them, the charging gun status includes whether the vehicle is plugged into the charging gun and whether the vehicle is not plugged into the charging gun.

[0061] S320: When it is detected that the vehicle is plugged into the charging gun, the first switch module is controlled to be disconnected, and the battery management system is controlled to output a first control signal to the first battery current converter, so that the first battery current converter works.

[0062] It should be noted that when the vehicle is plugged into the charging gun, the first power signal output by the charging gun is input to the battery management system through the first unidirectional conduction module, and the battery management system outputs a first control signal to the first battery current converter, so that the first battery current converter works. The first power signal output by the charging gun is also input to the control end of the second switch module, so that the second switch module is turned on, and the first current output by the first battery current converter is input to the five-in-one controller.

[0064] S410, detecting the status of the charging gun.

[0065] S420: When it is detected that the vehicle is plugged into the charging gun, identify the type of the first power signal output by the charging gun, where the type of the first power signal includes a slow charging power signal and a fast charging power signal.

[0066] It is understandable that the charging gun can be a fast charging gun or a slow charging gun. When the charging gun is a fast charging gun, the type of the first power signal is a fast charging power signal. When the charging gun is a slow charging gun, the type of the first power signal is a slow charging power signal.

[0067] S430: If the type of the first power signal is identified as a fast charging power signal, the first switch module is controlled to disconnect, and the battery management system is controlled to output a first control signal to the first battery current converter, so that the first battery current converter works while the vehicle current converter is controlled to output a second current to the heating and cooling unit.

[0068] It should be noted that when the vehicle is plugged into the charging gun, the first power signal output by the charging gun is input to the battery management system through the first unidirectional conduction module, and the battery management system outputs a first control signal to the first battery current converter, so that the first battery current converter works. The first power signal output by the charging gun is also input to the control end of the second switch module, so that the second switch module is turned on, and the first current output by the first battery current converter is input to the five-in-one controller. If it is a fast charge, the first switch module is controlled to be disconnected, and the battery management system is controlled to output the first control signal to the first battery current converter, so that the first battery current converter works, and the vehicle current converter is controlled to output the second current to the heat and cooling unit. It can ensure that the whole vehicle is not on high voltage and does not have the conditions for working, but the vehicle current converter can supply power to the heat and cooling unit, so that the heat and cooling unit works to charge and cool the battery.
