[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0046] According to the first aspect of this application, referring to Figures 1 to 4 This application provides a capacitor. The capacitor includes a housing 11, a capacitor assembly, and a first relay 14. The capacitor assembly is installed inside the housing 11. The first relay 14 is installed inside the housing 11. The first relay 14 is electrically connected to the capacitor assembly.

[0047] In this embodiment, by integrating both the capacitor assembly and the first relay 14 into the capacitor housing 11, the installation space for the first relay 14 is saved, and the distance between the first relay 14 and the capacitor assembly is shortened. Therefore, when the capacitor assembly and the first relay 14 are electrically connected using copper busbars, the length of the copper busbars can be shortened, saving the amount of copper busbars used and thus reducing production costs.

[0048] It is understood that the capacitor housing 11 can simultaneously accommodate the capacitor assembly and the first relay 14, thereby allowing the first relay 14 to be built into the capacitor, thus reducing the external space required to fix the first relay 14. For vehicle electronic control components, the electronic control components include capacitors and relays. When the electronic control component adopts the arrangement of the capacitor and the first relay 14 in the embodiments of this application, it can significantly save internal assembly space and assembly time, improving space utilization and assembly efficiency.

[0049] Because the first relay 14 is integrated into the capacitor, compared to an arrangement where the first relay 14 is located outside the housing 11, the distance between the first relay 14 and the capacitor assembly can be significantly shortened, thereby reducing the length of the copper busbar used to electrically connect the first relay 14 and the capacitor assembly. Based on the reduced copper busbar length, the amount of copper busbar used can be decreased, lowering the product cost and weight.

[0050] like Figure 1 As shown, in some embodiments, the capacitor assembly includes a first capacitor 12 and a second capacitor 13. The second capacitor 13 is connected in parallel with the first capacitor 12. A first relay 14 is connected in series with the second capacitor 13, and the first relay 14 is positioned close to the second capacitor 13.

[0051] It is understandable that the first capacitor 12 and the second capacitor 13 each serve different purposes and can act on different or the same electrical circuits. The first relay 14 is connected in series with the second capacitor 13 so that the first relay 14 can control the on / off state of the circuit containing the second capacitor 13. When the first relay 14 switches from the off state to the on state, the second capacitor 13 can be integrated into the circuit to perform its corresponding function. When the first relay 14 switches from the on state to the off state, the electrical connection between the second capacitor 13 and the circuit is broken.

[0052] By positioning the first relay 14 close to the second capacitor 13, the length of the copper busbar connecting the first relay 14 and the second capacitor 13 can be shortened, thereby reducing the amount of copper busbar used and lowering the cost and weight of the product.

[0053] In some embodiments, the first capacitor 12 is a bus capacitor, and the second capacitor 13 is a boost capacitor. During the boost charging process, the first relay 14 switches from the off state to the on state, so that the branch can perform energy storage, filtering, and voltage stabilization during the boost charging process.

[0054] In some embodiments, the first capacitor 12 may be configured as at least two, and at least two first capacitors 12 are connected in series.

[0055] Please continue reading. Figure 1 In some embodiments, the capacitor further includes a heat insulation element 15. The heat insulation element 15 is disposed within the housing 11. The heat insulation element 15 is located between the first relay 14 and the first capacitor 12, and / or between the first relay 14 and the second capacitor 13.

[0056] Understandably, the heat insulation component 15 can insulate the first capacitor 12 and the first relay 14, as well as the second capacitor 13 and the second relay 27. During capacitor operation, the first relay 14 will generate heat. Heat conduction from the first relay 14 to the first capacitor 12 and / or the second capacitor 13 may cause thermal damage to the first capacitor 12 and / or the second capacitor 13. The heat insulation component 15 blocks heat conduction to prevent heat damage to the first capacitor 12 and / or the second capacitor 13.

[0057] For example, when the first relay 14 generates more than 105 degrees Celsius during operation, the heat is conducted to the first capacitor 12 and / or the second capacitor 13, which may cause the first capacitor 12 and / or the second capacitor 13 to be damaged by heat.

[0058] In some embodiments, the heat insulation element 15 is placed only inside the housing 11 and does not form a direct connection with the housing 11. After potting compound is injected into the housing 11, the potting compound solidifies to form a potting compound layer, thereby fixing the position of the heat insulation element 15 inside the housing 11.

[0059] In some embodiments, a heat insulation member 15 is provided between the first relay 14 and the first capacitor 12. A heat insulation member 15 is also provided between the first relay 14 and the second capacitor 13.

[0060] In some embodiments, the heat insulation element 15 is a ceramic sheet, which has good thermal insulation properties and can effectively prevent heat conduction to the first capacitor 12 and / or the second capacitor 13, ensuring that the capacitors are not damaged by heat. Of course, the heat insulation element 15 can be made of other heat insulation materials, and the material of the heat insulation element 15 is not limited in the embodiments of this application.

[0061] Please continue reading. Figure 1 In some embodiments, the capacitor further includes a potting compound layer. The potting compound layer is disposed within the housing 11. The potting compound layer encapsulates the heat insulation element 15, the first capacitor 12, the second capacitor 13, and the first relay 14.

[0062] Understandably, after the first capacitor 12, the second capacitor 13, the first relay 14, and the heat insulation component 15 are all installed in the housing 11, potting compound needs to be injected into the housing 11 to achieve sealing and fixation. After the potting compound solidifies, it forms a potting compound layer to reliably fix the internal components.

[0063] Please continue reading. Figure 1 In some embodiments, the capacitor further includes a first connector 16 and a second connector 17. The first connector 16 and the second connector 17 are spaced apart within the housing 11. The first connector 16 is electrically connected to a first terminal of the first capacitor 12. The second connector 17 is electrically connected to a second terminal of the first capacitor 12.

[0064] Understandably, one end of the first connector 16 is electrically connected to the first terminal of the first capacitor 12, and the other end of the first connector 16 is used to electrically connect to the positive terminal of the battery pack 32. One end of the second connector 17 is electrically connected to the second terminal of the first capacitor 12, and the other end of the second connector 17 is used to electrically connect to the negative terminal of the battery pack 32. Thus, after the capacitor is applied to the vehicle's electronic control circuit, the battery pack 32 can be charged through this circuit.

[0065] The first capacitor 12 is connected between the positive and negative terminals of the battery pack 32, that is, between the positive and negative terminals of the DC bus 21. The first capacitor 12 can perform rectification and filtering functions.

[0066] In some embodiments, the first connector 16 and the second connector 17 are connection terminals of a busbar disposed in a capacitor. The first connector 16 and the second connector 17 are integrally formed with their respective corresponding busbars.

[0067] In some embodiments, the first connector 16 is electrically connected to the positive terminal of the first capacitor 12, and the second connector 17 is electrically connected to the negative terminal of the first capacitor 12.

[0068] Please continue reading. Figure 1 In some embodiments, the capacitor further includes a third connector 18 and a fourth connector 19. The third connector 18 and the fourth connector 19 are spaced apart within the housing 11. The third connector 18 is electrically connected to a first terminal of the first relay 14. The fourth connector 19 is electrically connected to a second terminal of the first capacitor 12.

[0069] Understandably, one end of the third connector 18 is electrically connected to the first end of the first relay 14, and the other end of the third connector 18 is used to electrically connect to the positive terminal of the charging pile or charging pile connector. One end of the fourth connector 19 is electrically connected to the second terminal of the first capacitor 12, and the other end of the fourth connector 19 is used to electrically connect to the negative terminal of the charging pile or charging pile connector. Thus, after the capacitor is applied to the vehicle's electronic control circuit, the battery pack 32 can be charged using the charging pile through this circuit.

[0070] In some embodiments, the third connector 18 and the fourth connector 19 are connection terminals of a busbar disposed in a capacitor. The third connector 18 and the fourth connector 19 are integrally formed with their respective corresponding busbars.

[0071] In some embodiments, the third connector 18 is electrically connected to the positive terminal of the first relay 14, and the fourth connector 19 is electrically connected to the negative terminal of the first capacitor 12.

[0072] Please continue reading. Figure 1 In some embodiments, the capacitor further includes a fifth connector 110 and a sixth connector 111. The fifth connector 110 and the sixth connector 111 are spaced apart within the housing 11. The fifth connector 110 is electrically connected to a first terminal of the first relay 14. The sixth connector 111 is electrically connected to a first terminal of the first capacitor 12.

[0073] Understandably, one end of the fifth connector 110 is electrically connected to the first terminal of the first relay 14, and the other end of the fifth connector 110 is used to electrically connect to the positive terminal of the IGBT module. One end of the sixth connector 111 is electrically connected to the first terminal of the first capacitor 12, and the other end of the sixth connector 111 is used to electrically connect to the negative terminal of the IGBT module.

[0074] It should be noted that the IGBT module includes the vehicle's drive motor 22. Specifically, one end of the fifth connector 110 is electrically connected to the first terminal of the first relay 14, and the other end of the fifth connector 110 is used as the positive terminal of the drive motor 22. One end of the sixth connector 111 is electrically connected to the first terminal of the first capacitor 12, and the other end of the sixth connector 111 is used as the negative terminal of the drive motor 22. Thus, when charging the battery pack 32 using a charging pile, the drive motor 22 in the IGBT module can be used as the inductor in the charging circuit to achieve DC charging or boost charging of the battery pack 32. By using the drive motor 22 in the IGBT module as the inductor in the charging circuit, the vehicle can be matched with more types of charging piles, and energy loss during the charging process can be ensured to be low. At the same time, by reusing the drive motor 22, costs can be reduced and space can be saved.

[0075] In some embodiments, the fifth connector 110 and the sixth connector 111 are connection terminals of a busbar disposed in a capacitor. The fifth connector 110 and the sixth connector 111 are integrally formed with their respective corresponding busbars.

[0076] In some embodiments, the first relay 14 is electrically connected to the capacitor assembly via an electrical connector. The first relay 14 is soldered to the electrical connector.

[0077] Understandably, the electrical connector is a copper busbar. The first relay 14 forms an electrical connection with the capacitor assembly through the copper busbar. The first relay 14 is welded to the copper busbar to prevent adhesive from seeping between the terminals of the first relay 14 and the copper busbar during potting inside the housing 11, thus preventing connection failure between the first relay 14 and the electrical connector.

[0078] In some embodiments, the first relay 14 is laser-welded to the electrical connector.

[0079] According to a second aspect of this application, a circuit structure is provided that includes the capacitor described above. This circuit structure possesses all the beneficial effects of the capacitor described above, which will not be elaborated further herein.

[0080] like Figure 2 As shown, in some embodiments, the circuit structure further includes a DC bus 21, and the capacitor assembly includes a first capacitor 12 and a second capacitor 13. The two ends of the first capacitor 12 are electrically connected to the positive and negative terminals of the DC bus 21, respectively. The second capacitor 13 is connected in parallel with the first capacitor 12 and is electrically connected to the negative terminal of the DC bus 21. One end of the first relay 14 is connected in series with the second capacitor 13. The other end of the first relay 14 is configured to connect to the positive terminal of the charging connector 31. The second capacitor 13 is a boost capacitor.

[0081] Understandably, the first capacitor 12 is located between the positive and negative terminals of the DC bus 21, serving functions such as rectification and filtering. The second capacitor 13 is a boost capacitor, and the first relay 14 is connected in series with the second capacitor 13, enabling the first relay 14 to control the on / off state of the circuit containing the second capacitor 13. During boost charging, the first relay 14 switches from the off state to the on state, allowing this branch to perform energy storage, filtering, and voltage stabilization during boost charging. The charging connector 31 is used to connect to a charging pile, thereby using the charging pile to charge the battery pack 32.

[0082] When the vehicle is DC charged using this circuit structure, the first relay 14 is in the open state. At this time, the negative terminal of the charging pile is directly connected to the negative terminal of the battery pack 32 through the third relay 28. The positive terminal of the charging pile is connected to the positive terminal of the battery pack 32 through the second relay 27 and the DC bus 21.

[0083] When the vehicle uses this circuit structure for boost charging, the first relay 14 is in the conducting state. At this time, the negative terminal of the charging pile is directly connected to the negative terminal of the battery pack 32 through the third relay 28. The positive terminal of the charging pile is connected to the positive terminal of the battery pack 32 through the second relay 27 and the DC bus 21. Because the first relay 14 is conducting, the second capacitor 13 can be used to absorb the ripple current and filter the DC terminal, thereby enabling boost charging even when the voltage of the charging pile is lower than the voltage of the battery pack 32.

[0084] The two charging methods mentioned above are determined by the vehicle's in-vehicle infotainment system. This application embodiment does not restrict the charging method or the conditions for switching between them.

[0085] In some embodiments, the first capacitor 12 may be configured as at least two, and at least two first capacitors 12 are connected in series.

[0086] like Figure 3 As shown, in some embodiments, the circuit structure further includes a drive motor 22. A first terminal of the drive motor 22 is configured to be electrically connected to the positive terminal of the charging connector 31 via a second relay 27. A second terminal of the drive motor 22 is configured to be electrically connected to the positive terminal of the battery pack 32.

[0087] Understandably, the drive motor 22 is connected in parallel with the first capacitor 12 and the first relay 14. The first terminal of both the drive motor 22 and the first terminal of the first relay 14 are electrically connected to the positive terminal of the charging connector 31. The second terminal of the drive motor 22 and the first terminal of the first capacitor 12 are both electrically connected to the positive terminal of the battery pack 32. When the charging station uses this circuit structure to charge the battery pack 32, the drive motor 22 can act as an inductor to perform DC charging or boost charging of the battery pack 32.

[0088] When the vehicle is running, the drive motor 22 can drive the wheels to rotate, enabling the vehicle to move forward and backward. When the vehicle is charging, it is in a parked state, and the drive motor 22 does not need to drive the wheels. At this time, the drive motor 22 is used as an inductor in the charging circuit to achieve multiplexing of the drive motor 22, thereby reducing the use of inductors in the charging circuit. This saves costs and installation space, and allows the vehicle to be matched with more types of charging piles while ensuring low energy loss during the charging process.

[0089] like Figure 4 As shown, the circuit structure in this embodiment further includes a first magnetic ring 23. The first magnetic ring 23 is disposed near the charging connector 31. The first magnetic ring 23 can perform filtering and high / low frequency adjustment.

[0090] Please continue reading. Figure 4 The circuit structure in this embodiment also includes an AC Hall effect sensor 24. The AC Hall effect sensor 24 is located between the vehicle's transmission and the IGBT module. The AC Hall effect sensor 24 can monitor the charging current and provides safety protection. It is understood that the vehicle's infotainment system has a charging current threshold. When the AC Hall effect sensor 24 detects that the charging current exceeds the threshold, the infotainment system can limit the charging current and send an alarm signal to the terminal.

[0091] Please continue reading. Figure 4 The circuit structure in this embodiment also includes a fuse 25. Two fuses 25 can be configured to melt and protect the circuit in the event of a short circuit, overheating, or other fault.

[0092] Please continue reading. Figure 4 The circuit structure in this embodiment further includes a second magnetic ring 26. The second magnetic ring 26 is located near the DC bus 21. The second magnetic ring 26 can perform filtering and high / low frequency adjustment.

[0093] According to a third aspect of this application, an electronic device is provided, which includes the circuit structure described above. This electronic device possesses all the beneficial effects of the circuit structure described above, which will not be elaborated further herein.

[0094] According to a fourth aspect of this application, a vehicle is provided that includes the aforementioned electronic equipment, and the vehicle has all the beneficial effects of the aforementioned electronic equipment, which will not be repeated here.
