Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0050] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] The following is for reference. Figures 1-14 The controller integration module 100 according to an embodiment of the present utility model is small in size, highly compact, occupies little space, and is lightweight, which is beneficial for production line assembly and has low cost.

[0052] like Figures 1-14 As shown, a controller integration module 100 according to an embodiment of the present invention includes: a capacitor 1 and two IGBTs, a DC bus copper bus assembly 3 and two sets of charging power distribution structures 4.

[0053] First, it should be noted that the controller integration module 100 is mainly used to control the coordinated operation of the two motors 8, so as to achieve efficient and precise control of the motors 8, thereby improving vehicle performance, reliability and efficiency.

[0054] The controller integration module 100 includes a capacitor 1 and two IGBTs. The capacitor 1 is an important component in the controller integration module 100. The capacitor 1 is a bus capacitor, which is mainly used to stabilize the DC bus voltage and protect the device. The two IGBTs are core power switching devices, which control the energy conversion and transmission of the two motors 8 respectively, so as to realize the independent drive, coordinated control and efficient energy management of the motors 8.

[0055] In this circuit, capacitor 1 is electrically connected to the IGBT, meaning that capacitor 1 is connected in parallel across the two ends of the DC bus and connected to the input terminal of the IGBT through the circuit. This allows capacitor 1 to absorb and release charge in real time to stabilize the DC bus voltage. During the switching process, the IGBT will generate high-frequency pulse current and voltage fluctuations. Capacitor 1 can absorb these fluctuations and provide stable DC voltage support for the IGBT.

[0056] The two IGBTs are electrically connected to the two motors 8 in a one-to-one correspondence, that is, one IGBT is electrically connected to one motor 8 and the other IGBT is electrically connected to the other motor 8. This allows each IGBT to independently control the current, voltage and frequency of the corresponding motor 8, thereby achieving the effect of driving two motors 8 simultaneously. In this way, even if one IGBT fails, the other IGBT can still drive the corresponding motor 8 to ensure the normal operation of the motor 8, provide power to the vehicle and prevent the vehicle from losing control.

[0057] Furthermore, the DC bus copper busbar assembly 3 and the two sets of charging power distribution structures 4 are included. The DC bus copper busbar assembly 3 is electrically connected to the capacitor 1, and the two sets of charging power distribution structures 4 are electrically connected to the capacitor 1 and integrated with the capacitor 1. Each charging power distribution structure 4 includes a DC charging copper busbar assembly 41 and at least one relay.

[0058] Specifically, the DC bus copper bus assembly 3 is the core conductive carrier used to carry current and realize circuit connection. The DC bus copper bus assembly 3 is electrically connected to the capacitor 1, that is, the DC bus copper bus assembly 3 can transmit DC power to the capacitor 1, so that the capacitor 1 can filter the voltage and store energy, providing stable DC power to the two IGBTs.

[0059] Two sets of charging power distribution structures 4 are used to charge the battery pack. Each set of charging power distribution structures 4 can be connected to a DC charging interface 79, so that the DC power flowing through the two DC charging interfaces 79 can pass through the two sets of charging power distribution structures 4 and enter the controller integrated module 100. The two sets of charging power distribution structures 4 are electrically connected to capacitors 1, so that when the battery pack supplies power to the two motors 8, the current can flow through capacitors 1 to the IGBTs to drive the motors 8. When charging the battery pack, the DC power flowing through the two sets of charging power distribution structures 4 can flow through capacitors 1 and then to the battery pack.

[0060] Each charging power distribution structure 4 includes a DC charging copper busbar assembly 41 and at least one relay. That is, each charging power distribution structure 4 may include one, two or more relays. The DC charging copper busbar assembly 41 and at least one relay are used to realize the circuit connection when charging the battery pack. In other words, the DC charging interface 79 is electrically connected to the DC busbar assembly 3 and the capacitor 1 through the DC charging copper busbar assembly 41 and at least one relay.

[0061] Furthermore, the two sets of charging power distribution structures 4 are integrated with capacitor 1 into a single unit, that is, the DC charging copper busbar assembly 41 and at least one relay are integrated with capacitor 1. This reduces the number of relay mounting brackets and large fuse mounting brackets, thereby reducing the size of the controller integrated module 100, reducing its space occupation, making the controller integrated module 100 more compact, which is beneficial for production line assembly, optimizing assembly processes, reducing costs, and reducing the overall weight of the controller integrated module 100. The integration of the two sets of charging power distribution structures 4 with capacitor 1 also allows the two sets of charging power distribution structures 4 to be directly electrically connected to capacitor 1, reducing the number of connecting copper busbars required for the connection between the charging power distribution structures 4 and capacitor 1. In addition, the two sets of charging power distribution structures 4 share a DC bus, which reduces the DC charging circuit path, saves copper busbar paths, and saves electrical control layout space.

[0062] According to the controller integration module 100 of this utility model embodiment, by electrically connecting two sets of charging power distribution structures 4 to capacitor 1 and integrating them into one unit, each charging power distribution structure includes a DC charging copper busbar assembly 41 and at least one relay, the setting of relay fixing base and large fuse fixing base is reduced, thereby reducing the volume of the controller integration module 100, reducing the space occupied by the controller integration module 100, making the controller integration module 100 structure more compact, which is conducive to production line assembly, optimizing assembly process, reducing cost, reducing the overall weight of the controller integration module 100, and allowing the two sets of charging power distribution structures 4 to share a DC bus, thereby reducing the DC charging circuit path, saving copper busbar path, and saving electrical control layout space.

[0063] In some embodiments, each DC charging copper busbar assembly 41 includes a DC charging positive copper busbar 411 and a DC charging negative copper busbar 412.

[0064] Specifically, the DC charging positive copper busbar 411 is a conductive component in the DC charging circuit, mainly used to realize current transmission and electrical connection. The DC charging positive copper busbar 411 and the DC charging negative copper busbar 412 are responsible for transmitting the high-voltage DC power input at the DC charging interface 79 to the controller integrated module 100, realizing the connection of the DC charging circuit, and finally charging the battery pack.

[0065] The DC charging positive copper busbar 411 serves as the conductive path for the high-voltage positive terminal in the DC charging circuit. It is connected to the positive output terminal of the high-voltage DC charging interface 79, transmitting DC power into the DC charging circuit. The DC charging negative copper busbar 412 serves as the conductive path for the high-voltage negative terminal in the DC charging circuit. It is connected to the negative output terminal of the high-voltage DC charging interface 79, forming a complete DC charging circuit. Simultaneously, the DC charging negative copper busbar 412 can be grounded to ensure charging safety. Thus, the DC charging positive copper busbar 411 and DC charging negative copper busbar 412 together constitute the high-voltage circuit for DC charging, achieving closed-loop current transmission from the DC charging interface 79 to the battery pack, ensuring the continuity and efficiency of the charging process.

[0066] Furthermore, each charging power distribution structure 4 has three relays, including a first relay 42, a second relay 43, and a third relay 44. The DC charging negative copper busbar 412 is electrically connected to the first relay 42, and the DC charging positive copper busbar 411 is electrically connected to the second relay 43 and the third relay 44 respectively. The first relay 42, the second relay 43, and the third relay 44 are electrically connected to the control board 51 respectively.

[0067] Specifically, such as Figures 3-5 , Figures 9-10 As shown, the DC charging negative copper busbar 412 is electrically connected to the first relay 42, so that DC current can be transmitted between the DC charging negative copper busbar 412 and the first relay 42, realizing the connection of the conductive channel of the high voltage negative terminal in the DC charging circuit. The DC charging positive copper busbar 411 is electrically connected to the third relay 44, so that DC current can be transmitted between the DC charging positive copper busbar 411 and the third relay 44, realizing the connection of the conductive channel of the high voltage positive terminal in the DC charging circuit. The DC charging positive copper busbar 411 is also electrically connected to the second relay 43, so that DC current can be transmitted between the DC charging positive copper busbar 411 and the second relay 43. The charging power distribution structure 4 also includes a boost capacitor 75. When the second relay 43 is energized, the circuit of the boost capacitor 75 can be connected, so as to charge the boost capacitor 75.

[0068] The first relay 42, the second relay 43, and the third relay 44 are electrically connected to the control board 51, so that signal transmission can be performed between the first relay 42, the second relay 43, and the third relay 44 and the control board 51. The control board 51 can send signals to the first relay 42, the second relay 43, and the third relay 44. After receiving the signals from the control board 51, the first relay 42, the second relay 43, and the third relay 44 will disconnect or engage to realize the connection or disconnection of the circuit.

[0069] In practical design, such as Figures 3-6As shown, each charging power distribution structure 4 also includes a DC magnetizing ring 76, which is sleeved on the DC charging positive copper busbar 411 and the DC charging negative copper busbar 412 to achieve electrical connection between the DC magnetizing ring 76 and the DC charging positive copper busbar 411 and the DC charging negative copper busbar 412, thereby suppressing electromagnetic interference. In this way, the negative output terminal of the DC charging interface 79 can be electrically connected to the first relay 42 first through the DC magnetizing ring 76 and then through the DC charging negative copper busbar 412. The positive output terminal of the DC charging interface 79 can be electrically connected to the second relay 43 and the third relay 44 first through the DC magnetizing ring 76 and then through the DC charging positive copper busbar 411. The second relay 43 is electrically connected to the DC charging positive copper busbar 411 through a boost copper busbar 72, which is welded to the DC charging positive copper busbar 411 and directly connected to the second relay 43.

[0070] In some embodiments, the DC charging positive copper busbar 411, the DC charging negative copper busbar 412, the first relay 42, the second relay 43, and the third relay 44 are all integrally formed with the capacitor 1 by injection molding.

[0071] In other words, the DC charging positive copper busbar 411, DC charging negative copper busbar 412, first relay 42, second relay 43 and third relay 44 in the two sets of charging power distribution structures 4 are all integrated with the capacitor 1 by injection molding, thereby reducing the number of relay mounting brackets in the two sets of charging power distribution structures 4, that is, reducing the number of relay mounting brackets by six, and also reducing the number of large fuse mounting brackets, thus reducing the size of the controller integrated module 100.

[0072] Alternatively, the bus magnetic ring 77 in the battery pack power supply circuit and the boost copper bus 72 in the DC charging circuit can be injection molded together with the capacitor 1 to further reduce the internal space of the controller integration module 100, making the manufacturing process more convenient.

[0073] Therefore, by integrating capacitor 1 with two sets of charging and power distribution structures 4 into one unit, the two DC charging circuits are connected to capacitor 1 inside the injection-molded body and finally output to the battery pack simultaneously, reducing the entire DC charging circuit path and the number of connecting copper busbars.

[0074] In actual design, the first relay 42, the second relay 43, the third relay 44, the DC charging positive copper busbar 411, the DC charging negative copper busbar 412, the busbar magnetic ring 77 and the boost copper busbar 72 can be integrated into a single injection molding. Then, epoxy resin is poured into the capacitor 1 and waited for it to solidify to form a whole with the injection molded part.

[0075] In some embodiments, the DC bus copper bus assembly 3 includes a DC bus positive copper bus 31 and a DC bus negative copper bus 32, which are electrically connected to the capacitor 1 respectively.

[0076] Specifically, see the attached document. Figures 3-5 As shown, the DC bus copper busbar assembly 3 includes a DC busbar positive copper busbar 31 and a DC busbar negative copper busbar 32. The DC busbar positive copper busbar 31 and the DC busbar negative copper busbar 32 are electrically connected to the capacitor 1, that is, the DC busbar positive copper busbar 31 is electrically connected to the positive terminal of the capacitor 1, and the DC busbar negative copper busbar 32 is electrically connected to the negative terminal of the capacitor 1, so that when the DC busbar signal enters the controller integrated module 100, it can pass through the capacitor 1.

[0077] Furthermore, the DC charging positive copper busbar 411 of both charging and power distribution structures 4 is electrically connected to the DC bus positive copper busbar 31, the DC bus negative copper busbar 32 is electrically connected to the negative terminal of capacitor 1, the second relay 43 is electrically connected to the positive terminal of capacitor 1 through the second relay transfer copper busbar 43, and the third relay 44 is electrically connected to the N-line copper busbar 61 of the three-phase copper busbar assembly 6 through the third relay transfer copper busbar 442.

[0078] Specifically, the DC charging positive copper busbars 411 of both charging power distribution structures 4 are electrically connected to the DC bus positive copper busbar 31, so that current can flow between the DC charging positive copper busbar 411 and the DC bus positive copper busbar 31. The DC bus positive copper busbar 31 is electrically connected to the positive terminal of capacitor 1, and the DC bus negative copper busbar 32 is electrically connected to the negative terminal of capacitor 1, so that current can flow through capacitor 1. The second relay 43 is electrically connected to the positive terminal of capacitor 1 via the second relay transfer copper busbar 43, and the third relay 44 is connected to the N-phase of the three-phase copper busbar assembly 6 via the third relay transfer copper busbar 442. The copper busbar 61 is electrically connected to form a positive circuit for DC charging. This allows the positive output terminal of the DC charging interface 79 to pass through the third relay 44, the boost capacitor 75, and then through the N-line copper busbar 61 of the three-phase copper busbar assembly 6 to connect to the motor 8. After the DC current enters the motor 8, the motor winding 81 acts as an inductor, returning to the IGBT. The output then passes through capacitor 1 and returns to the positive terminal of the battery pack. The negative output terminal of the DC charging interface 79 is connected to the negative terminal of the battery pack through the first relay 42, forming a negative circuit for DC charging, thus achieving a complete DC charging circuit. Through the above connections, a complete circuit can be formed for the battery pack to supply power to the motor 8. When the battery pack supplies power, the current passes through the DC bus connector, then through the DC bus positive copper busbar 31 and the bus magnetic ring 77, then through capacitor 1, and is converted to AC power by the IGBT before flowing to the motor 8 to drive it. Afterward, the current returns to capacitor 1 and then through the DC bus negative copper busbar 32 back to the negative terminal of the battery pack.

[0079] like Figure 7 and Figure 8 As shown, when charging the battery pack, Figure 7 and Figure 8 The thick solid line shown represents the negative electrode circuit path. Figure 7 and Figure 8 The thin dashed lines shown represent the positive electrode circuit path, and as... Figure 10 As shown, Figure 10 The thick solid line shown represents the positive terminal connection path during DC charging. Figure 10 The thick dashed line shown represents the negative terminal connection path during DC charging, as... Figure 11 As shown, Figure 11 The thick solid line shown represents the positive terminal connection path when the battery pack is powered. Figure 11 The thick dashed line shown represents the negative terminal connection path when the battery pack is powered.

[0080] It should be noted that, in order to protect the boost capacitor 75, the second relay 43 remains in the open state when driving the motor 8 to prevent current from damaging the boost capacitor 75. The second relay 43 can be set as a 250A boost relay, and the first relay 42 and the third relay 44 can be set as 400A positive and negative relays.

[0081] In some embodiments, the DC bus negative copper busbar 32 is configured with 3 X capacitors 1 and / or 4 sets of Y capacitors 1.

[0082] Specifically, when the battery pack supplies power to the motor 8 to drive the motor 8 to work, in order to reduce the differential mode current components of the total positive and total negative lines during driving, three X capacitors 321 can be configured on the DC bus negative copper bus 32. The three X capacitors 321 can be connected across the DC bus negative copper bus 32 and the DC bus positive copper bus 31 respectively to form a parallel structure. In order to reduce the common mode current components of the total positive and total negative lines during driving, four sets of Y capacitors 322 can be configured on the DC bus negative copper bus 32. The four sets of Y capacitors 322 can be connected across the DC bus negative copper bus 32 or the DC bus positive copper bus 31 and ground respectively.

[0083] Therefore, by using three X capacitors 321 to target differential-mode interference between the total positive and total negative lines, and by using four sets of Y capacitors 322 to target common-mode interference between the total positive and total negative lines, the motor 8 and the controller integrated module 100 can be protected, and their service life can be extended.

[0084] In other embodiments, a current sampling Hall effect sensor 323 is installed on the negative copper busbar 32 of the DC bus.

[0085] Specifically, the current sampling Hall 323 can monitor the bus current in real time. It senses the current through a magnetic field. When the current detected by the current sampling Hall 323 exceeds the preset current value, the controller integrated module 100 will quickly trigger the protection mechanism to prevent the IGBT and motor 8 from being damaged due to overcurrent.

[0086] like Figure 2 , Figure 3 and Figure 5 As shown, the current sampling Hall 323 in this embodiment can be directly fixedly installed on the negative copper busbar 32 of the DC bus to complete the current acquisition. It does not need to pass through the negative copper busbar 32 of the DC bus to be fixed, which reduces the assembly complexity and the space required for assembly.

[0087] In some other embodiments, a negative active fuse 71 is connected between the DC bus negative copper busbar 32 and the capacitor 1.

[0088] Specifically, the negative active fuse 71 can be connected between the negative copper busbar 32 of the DC bus and the negative terminal of capacitor 1. In this way, when a short circuit occurs on the battery pack side or the bus side, the negative active fuse 71 can quickly cut off the current to prevent the fault from spreading to capacitor 1, IGBT, and motor 8. When an internal short circuit occurs in capacitor 1, the negative active fuse 71 can also limit the short circuit current to prevent capacitor 1 from exploding.

[0089] It should be noted that by molding the charging power distribution structure 4 and the capacitor 1 into one piece, only two copper busbars are needed to connect the DC charging magnetizing ring 76, the first relay 42, the negative active fuse 71, and the bus magnetic ring 77. This reduces the number of negative transfer copper busbars and reduces the number of busbars in each of the two sets of charging power distribution structures 4, further reducing the size of the controller integrated module 100. It also facilitates production line assembly and optimizes the assembly process.

[0090] In practical design, a set of Y capacitors 413 can be configured at the DC charging interface 79 to reduce the common-mode current components of the total positive and total negative lines on the DC charging circuit.

[0091] In some embodiments, the second relay 43 is connected to a boost copper busbar 72, which is soldered to the DC charging positive copper busbar 411.

[0092] Specifically, such as Figures 9-11 As shown, DC charging and boost charging share a common circuit. When the second relay 43 is energized, the boost charging circuit is activated, as shown below. Figures 5-8 As shown, the boost copper busbar 72 is electrically connected to the DC charging positive copper busbar 411. DC power can flow through the DC charging positive copper busbar 411, the boost copper busbar 72, and the second relay 43 to the boost capacitor 75, thereby increasing the voltage.

[0093] In some other embodiments, the first relay 42 is provided with a first relay pin 421 that is electrically connected to the control board 51.

[0094] In other words, the first relay 42 is electrically connected to the control board 51 through the first relay pin 421, so that the control board 51 can control the first relay 42 to be engaged or disengaged. In actual design, the first relay pin 421 can be directly soldered to the relay adapter board 78 and then connected to the control board 51 through the signal harness.

[0095] In some other embodiments, the second relay 43 is provided with a second relay pin 431 that is electrically connected to the control board 51.

[0096] In other words, the second relay 43 is electrically connected to the control board 51 through the second relay pin 431, so that the control board 51 can control the second relay 43 to be engaged or disengaged. In actual design, the second relay pin 431 can be directly soldered to the relay adapter board 78 and then connected to the control board 51 through the signal harness.

[0097] In some other embodiments, the third relay 44 is provided with a third relay pin 441 that is electrically connected to the control board 51.

[0098] In other words, the third relay 44 is electrically connected to the control board 51 through the third relay pin 441, so that the control board 51 can control the third relay 44 to be engaged or disengaged. In actual design, the third relay pin 441 can be directly soldered to the relay adapter board 78 and then connected to the control board 51 through the signal harness.

[0099] Therefore, by electrically connecting the three relays to the control board 51 through their respective relay pins, space is saved, the assembly process is simplified, screws and sampling harnesses are reduced, and the construction of automated production lines is facilitated.

[0100] In some embodiments, the positive terminal of capacitor 1 is welded to the positive terminal of IGBT via copper busbar 721, the negative terminal of capacitor 1 is welded to the negative terminal of IGBT via copper busbar 722, and the output terminal of IGBT is electrically connected to the three-phase copper busbar assembly 6.

[0101] Specifically, the positive terminal of capacitor 1 is welded to the positive terminal of the IGBT via copper busbar 721, thus electrically connecting the positive terminal of capacitor 1 to the positive terminal of the IGBT. The negative terminal of capacitor 1 is welded to the negative terminal of the IGBT via copper busbar 722, thus electrically connecting the negative terminal of capacitor 1 to the negative terminal of the IGBT, thereby forming a DC bus channel that connects capacitor 1 and the IGBT, allowing capacitor 1 to provide a stable DC voltage to the IGBT. The output terminal of the IGBT is electrically connected to the three-phase copper busbar assembly 6, enabling the IGBT to convert the DC voltage to AC voltage via high-frequency switching to provide three-phase AC power to the motor 8.

[0102] Furthermore, the IGBT is equipped with a Hall element 21, and the three-phase copper busbar assembly 6 passes through the Hall element 21. Two phases of the three-phase copper busbar assembly 6 are equipped with three-phase active fuses 62 and connected to the motor 8.

[0103] Specifically, the Hall element 21 detects the magnetic field generated by the collector or emitter current of the IGBT and outputs a voltage signal proportional to the current to achieve real-time current monitoring, which is conducive to better control of the motor 8 and prevents the motor 8 from overloaded or losing steps. When the Hall element 21 detects an abnormal current, it can trigger a protection mechanism to immediately shut off the IGBT drive signal, cut off the current path, and prevent damage to the IGBT.

[0104] The three-phase copper busbar assembly 6 passes through the Hall element 21, which can be directly fixed to the IGBT to achieve a fixed installation of the Hall element 21. Two phases of the three-phase copper busbar assembly 6 are equipped with a three-phase active fuse 62 and connected to the motor 8. That is, the three-phase active fuse 62 is connected between the two phase copper busbars and the motor 8. In the event of an abnormality, the controller integrated module 100 can quickly break the copper busbar to perform power-off protection, prevent damage to the motor 8, and improve the safety of the controller integrated module 100.

[0105] In some embodiments, such as Figure 1 As shown, a driver board 52 is fixed on the IGBT. The driver board 52 is used to control the IGBT's turn-on and turn-off and protect the IGBT. A shielding plate 53 is installed above the driver board 52. As a high-frequency switching device, the IGBT will generate strong electromagnetic interference during the turn-on and turn-off process. The shielding plate 53 can suppress electromagnetic interference to protect the circuit. A control board 51 is installed above the shielding plate 53. The control board 51 processes various signals from the motor 8, sensor and driver board 52, as well as controls the on and off of components such as relays.

[0106] The control board 51 is electrically connected to the drive board 52, and the drive board 52 is electrically connected to the IGBT, so that the control board 51 can send control signals to the drive board 52. After receiving the signal from the control board 51, the drive board 52 can control the IGBT to turn on and off, thereby adjusting the speed, torque or power output of the motor 8.

[0107] In some embodiments, the controller integration module 100 further includes a controller housing 9, in which the capacitor 1, IGBT, DC bus copper bus assembly 3 and charging power distribution structure 4 are all installed.

[0108] Specifically, such as Figure 1 and Figure 13 As shown, the controller integration module 100 also includes a controller housing 9. The controller housing 9 has an internal accommodating space. The capacitor 1, IGBT, DC bus copper bus assembly 3 and charging power distribution structure 4 are all installed in the accommodating space to protect the capacitor 1, IGBT, DC bus copper bus assembly 3 and charging power distribution structure 4 from damage caused by external impacts, foreign object corrosion, etc., which would prevent the controller integration module 100 from working properly.

[0109] In some embodiments, a cooling channel is formed inside the controller housing 9, which is used to cool and exchange heat with the capacitor 1, IGBT, DC bus copper bus assembly 3 and / or charging power distribution structure 4.

[0110] Specifically, the coolant can flow in the cooling channel, and during the flow, it cools and exchanges heat with capacitor 1, IGBT, DC bus copper bus assembly 3 and charging power distribution structure 4, so as to achieve effective heat dissipation of capacitor 1, IGBT, DC bus copper bus assembly 3 and charging power distribution structure 4, and improve the operating efficiency of controller integrated module 100.

[0111] In some embodiments, the controller housing 9 includes an upper housing 91 and a lower housing 92, with the upper housing 91 mounted on the lower housing 92 and located in the upper region of the lower housing 92.

[0112] Specifically, such as Figure 13 and Figure 14 As shown, the controller housing 9 includes an upper housing 91 and a lower housing 92. The interior of the lower housing 92 is hollow to form an accommodating space. The structural dimensions of the upper housing 91 are smaller than those of the lower housing 92, so that the upper housing 91 can be installed in the upper area of ​​the lower housing 92.

[0113] Furthermore, capacitor 1, IGBT, DC bus copper bus assembly 3 and charging power distribution structure 4 are installed in the upper housing 91, and power supply 73 is installed in the lower housing 92. Cooling channels are formed in the upper housing 91 and / or the lower housing 92.

[0114] Specifically, such as Figure 13 and Figure 14As shown, capacitor 1, IGBT, DC bus copper bus assembly 3, and charging power distribution structure 4 are installed in the upper housing 91 to support the installation of capacitor 1, IGBT, DC bus copper bus assembly 3, and charging power distribution structure 4. Power supply 73 is installed in the lower housing 92. Power supply 73 is a device required during AC charging. By installing power supply 73 in the lower housing 92, the power supply 73 and capacitor 1, IGBT, DC bus copper bus assembly 3, and charging power distribution structure 4 are installed in a layered manner, making the controller integration module 100 more compact.

[0115] The upper housing 91 may have a cooling channel, or the lower housing 92 may have a cooling channel, or both the upper housing 91 and the lower housing 92 may have cooling channels, in order to dissipate heat from the capacitor 1, IGBT, DC bus copper bus assembly 3, charging and power distribution structure 4 and power supply 73.

[0116] In some embodiments, the cooling channel includes a lower channel 921 formed in the lower housing 92 and an upper channel 911 formed in the upper housing 91. The lower housing 92 is also provided with an inlet 922 and an outlet 923, and the inlet 922, the lower channel 921, the upper channel 911 and the outlet 923 are connected in sequence.

[0117] In other words, the coolant can enter the lower flow channel 921 from the inlet 922 and circulate within the lower flow channel 921 to cool the power supply 73 inside the lower housing 92. Then, the coolant flows from the lower flow channel 921 to the upper flow channel 911 and circulates within the upper flow channel 911 to cool the capacitor 1, IGBT, DC bus copper bus assembly 3, and charging power distribution structure 4 in the upper housing 91. Finally, the coolant that has completed heat exchange flows out from the outlet 923.

[0118] As a result, the cooling channel is three-dimensional, and the coolant first passes through the lower housing 92 and then through the upper housing 91, thus achieving overall heat dissipation of the controller integrated module 100.

[0119] In some embodiments, the lower flow channel 921 includes a connected inlet flow channel 9211 and an outlet flow channel 9212, which are spaced apart and distributed on both sides of the power supply 73.

[0120] In other words, the inlet 922 is connected to the inlet channel 9211, and the inlet channel 9211 is connected to the outlet channel 9212. Thus, the coolant can enter the inlet channel 9211 from the inlet 922 and then enter the outlet channel 9212 from the inlet channel 9211 to achieve heat dissipation for the power supply 73. The inlet channel 9211 and the outlet channel 9212 are distributed on both sides of the power supply 73 at intervals, which can achieve effective heat dissipation for the entire power supply 73.

[0121] It should be noted that the power supply 73 has a separate coolant flow channel. Coolant can enter the coolant flow channel of the power supply 73 from one side through the inlet flow channel 9211 to dissipate heat from the power supply 73 as a whole, and then flow from the other side of the power supply 73 to the outlet flow channel 9212.

[0122] Specifically, such as Figure 13 and Figure 14 As shown, the inlet 922 and outlet 923 are formed inside the lower housing 92, and the inlet channel 9211 and outlet channel 9212 are formed in the lower housing 92 and the upper housing 91.

[0123] In some other embodiments, the upper flow channel 911 includes a first water flow channel 9111, a first heat dissipation groove 9112, a second water flow channel 9113, a second heat dissipation groove 9114 and a third water flow channel 9115 connected sequentially between the lower flow channel 921 and the outlet 923. The first heat dissipation groove 9112 and the second heat dissipation groove 9114 are arranged side by side and exchange heat with the two IGBTs respectively.

[0124] In other words, the coolant flowing out from the lower flow channel 921 can flow sequentially into the first water flow channel 9111, the first heat dissipation tank 9112, the second water flow channel 9113, the second heat dissipation tank 9114, and the third water flow channel 9115, so that the coolant circulates in a ring in the upper housing 91 to cool and dissipate heat for the two IGBTs. In the actual design, the coolant in the first heat dissipation tank 9112 and the second heat dissipation tank 9114 can exchange heat with the two IGBTs through the pins at the bottom of the IGBTs.

[0125] Specifically, such as Figure 13 As shown, a water channel plate 93 is connected to the upper part of the upper housing 91. A first water channel 9111 is formed on one side of the water channel plate 93, and a third water channel 9115 is formed on the other side of the water channel plate 93. A first heat dissipation groove 9112 and a second heat dissipation groove 9114 are formed on the upper side of the water channel plate 93. A second water channel 9113 is formed between the first heat dissipation groove 9112 and the second heat dissipation groove 9114. Thus, the first water channel 9111, the first heat dissipation groove 9112, the second water channel 9113, the second heat dissipation groove 9114 and the third water channel 9115 are connected to form an annular flow channel to achieve cooling and heat dissipation for the two IGBTs.

[0126] In other embodiments, capacitor 1 is fitted with a thermal pad 74 for heat exchange with the lower flow channel 921 and the upper flow channel 911.

[0127] Specifically, such as Figure 13As shown, the lower flow channel 921 and the upper flow channel 911 completely surround the capacitor 1 in the middle. A thermal pad 74 is provided between the lower side of the first heat dissipation groove 9112 and the upper side of the capacitor 1. A thermal pad 74 is provided between the lower side of the second heat dissipation groove 9114 and the upper side of the capacitor 1. A thermal pad 74 is provided between the lower side of the capacitor 1 and the lower casing 92. Thus, the heat generated by the capacitor 1 can be conducted to the upper flow channel 911 through the thermal pad 74 on the upper side of the capacitor 1, and the heat generated by the capacitor 1 can be conducted to the lower flow channel 921 through the thermal pad 74 on the lower side of the capacitor 1, thereby improving the heat dissipation efficiency of the capacitor 1.
