[0025] At present, the range-extended system of extended-range electric vehicles is composed of a dual-motor controller, a generator and a drive motor. The dual-motor controller is installed above the dual motors in an independent manner, and is also integrated in the dual-motor casing in the form of a power brick. However, the power brick currently uses side-by-side power modules, and the parallel GCU three-phase terminal block and the MCU three-phase terminal block are arranged just above the generator and the drive motor. This arrangement will leave the middle area of ​​the dual motors vacant and unusable, resulting in a low degree of integration of the system.

[0026] To solve the above problems, refer to Figures 1 - 3 , Figure 1 A schematic diagram of the structure of a range extender system provided in an embodiment of the present application is shown. Figure 2 A partial explosion of a range extender system provided by an embodiment of the present application is shown. Figure 1 , Figure 3 A partial explosion of a range extender system provided by an embodiment of the present application is shown. Figure 2 .

[0027] The present application provides a range extender system, including a thin film capacitor 1, a first power module 2, a second power module 3, a generator 4 and a drive motor 5, the first power module 2 is arranged on one side of the thin film capacitor 1, and the first power module 2 is connected to a first three-phase terminal block 21; the second power module 3 is arranged on a side of the thin film capacitor 1 away from the first power module 2, and the second power module 3 is connected to a second three-phase terminal block 31; the generator 4 and the drive motor 5 are arranged at intervals, the first three-phase terminal block 21 extends between the generator 4 and the drive motor 5, and the first three-phase terminal block 21 is connected to the terminal of the generator 4, the second three-phase terminal block 31 extends between the generator 4 and the drive motor 5, and the second three-phase terminal block 31 is connected to the terminal of the drive motor 5.

[0028] It should be understood that the range extender system includes a thin film capacitor 1, a first power module 2 and a second power module 3, and the thin film capacitor 1 has a length, a width and a height. The first power module 2 and the second power module 3 are respectively located on both sides of the thin film capacitor 1, the first power module 2 is located on one side of the width direction of the thin film capacitor 1, and the second power module 3 is located on the other side of the width direction of the thin film capacitor 1, so that the overall volume can be reduced. The first power module 2 is detachably connected to the thin film capacitor 1, and the connection method can be a bolt connection, which is not limited in this application. The second power module 3 is detachably connected to the thin film capacitor 1, and the connection method can be a bolt connection, which is not limited in this application.

[0029] Among them, one of the first power module 2 and the second power module 3 is a GCU power module (range extender generator controller power module), and the other is an MCU power module (motor controller power module), which is not limited in this application. In one example, the first power module 2 is a GCU power module, and the second power module 3 is an MCU power module. The first power module 2 is connected to a first three-phase terminal block 21, and the first three-phase terminal block 21 corresponds to the first power module 2. Therefore, when the first power module 2 is a GCU power module, the first three-phase terminal block 21 is a GCU three-phase terminal block (range extender generator controller three-phase terminal block); the second power module 3 is connected to a second three-phase terminal block 31, and the second three-phase terminal block 31 corresponds to the second power module 3, and the second three-phase terminal block 31 is an MCU three-phase terminal block (motor controller three-phase terminal block).

[0030] The generator 4 and the drive motor 5 are located below the film capacitor 1, and the generator 4 and the drive motor 5 are arranged side by side, and the generator 4 and the drive motor 5 are arranged at intervals along the radial direction of the generator 4 or the drive motor 5. The first three-phase terminal block 21 extends into the interval between the generator 4 and the drive motor 5, and the second three-phase terminal block 31 extends into the interval between the generator 4 and the drive motor 5, and the first three-phase terminal block 21 is connected to the terminal of the generator 4, and the second three-phase terminal block 31 is connected to the terminal of the drive motor 5.

[0031] In this application, by arranging the first power module 2 and the second power module 3 on both sides of the thin-film capacitor 1, the first three-phase terminal block 21 and the second three-phase terminal block 31 extend into the space between the generator 4 and the drive motor 5, so that the first three-phase terminal block 21 and the second three-phase terminal block 31 do not have to be located directly above the generator 4 and the drive motor 5, making full use of the space between the generator 4 and the drive motor 5, thereby improving the system integration degree.

[0032] In some alternative embodiments, the connection terminals of the generator 4 and the connection terminals of the drive motor 5 are in opposite directions. The connection terminals of the generator 4 face the first three-phase terminal block 21, and the connection terminals of the drive motor 5 face the second three-phase terminal block 31. Since the first three-phase terminal block 21 and the second three-phase terminal block 31 are arranged along the arrangement direction of the generator 4 and are parallel to the axial direction of the generator 4, when the connection terminals of the generator 4 are located at one end of the generator 4 facing the first three-phase terminal block 21, the convenience of connecting the generator 4 and the first three-phase terminal block 21 can be further improved. When the connection terminals of the drive motor 5 are located at one end of the drive motor 5 facing the second three-phase terminal block 31, the convenience of connecting the drive motor 5 and the second three-phase terminal block 31 can be further improved. At the same time, the lengths of the connection terminals of the generator 4 and the connection terminals of the drive motor 5 are reduced, and thus the cost is further reduced.

[0033] Refer to Figure 2 and Figure 3 In some alternative embodiments, a first relief groove 11 and a second relief groove 12 are respectively arranged on both sides of the thin-film capacitor 1. The first relief groove 11 is used to accommodate the components protruding from the first power module 2 towards the thin-film capacitor 1, and the second relief groove 12 is used to accommodate the components protruding from the second power module 3 towards the thin-film capacitor 1. The first relief groove 11 is recessed on one side of the thin-film capacitor 1 in the width direction, and the components protruding from the first power module 2 towards the thin-film capacitor 1 extend into the first relief groove 11, which can further reduce the volume of this application, and at the same time improve the stability and tightness of the connection between the first power module 2 and the thin-film capacitor 1. The second relief groove 12 is recessed on the other side of the thin-film capacitor 1 in the width direction, and the components protruding from the second power module 3 towards the thin-film capacitor 1 extend into the second relief groove 12, which can further reduce the volume of this application, and at the same time improve the stability and tightness of the connection between the second power module 3 and the thin-film capacitor 1.

[0034] Among them, the first relief groove 11 can be a single groove to accommodate all the components protruding from the first power module 2 towards the thin-film capacitor 1, or the first relief groove 11 can also be multiple grooves to respectively accommodate multiple different components protruding from the first power module 2 towards the thin-film capacitor 1. This application does not make any restrictions.

[0035] The second relief groove 12 may be a single groove for accommodating all the components of the second power module 3 that protrude towards the thin-film capacitor 1, or it may be multiple grooves for separately accommodating the components of different second power modules 3 that protrude towards the thin-film capacitor 1. This application does not impose any restrictions.

[0036] In some alternative embodiments, at least two first relief grooves 11 are provided and arranged at intervals along the length direction of the thin-film capacitor 1, and at least two second relief grooves 12 are provided and arranged at intervals along the length direction of the thin-film capacitor 1. The provision of at least two first relief grooves 11 enables the components of the multiple first power modules 2 that protrude towards the thin-film capacitor 1 to be separated, reducing the mutual influence between the components and further enhancing the connection stability between the thin-film capacitor 1 and the first power module 2. The provision of at least two second relief grooves 12 enables the components of the multiple second power modules 3 that protrude towards the thin-film capacitor 1 to be separated, reducing the mutual influence between the components and further enhancing the connection stability between the thin-film capacitor 1 and the second power module 3.

[0037] In some alternative embodiments, a first sealing ring 22 and a second sealing ring 32 are further included. The first sealing ring 22 surrounds the first power module 2 and is configured to extend into the first relief groove 11, and the second sealing ring 32 surrounds the second power module 3 and is configured to extend into the second relief groove 12. The provision of the first sealing ring 22 can seal the first power module 2 into the first relief groove 11, improving the connection stability and sealing performance between the first power module 2 and the thin-film capacitor 1. The number of the first sealing rings 22 is equal to the number of the first relief grooves 11. The provision of the second sealing ring 32 can seal the second power module 3 into the second relief groove 12, improving the connection stability and sealing performance between the second power module 3 and the thin-film capacitor 1. The number of the second sealing rings 32 is equal to the number of the second relief grooves 12.

[0038] In some alternative embodiments, a first cooling channel is further provided in the first relief groove 11 for cooling the first power module 2, and a second cooling channel is further provided in the second relief groove 12 for cooling the second power module 3. When the first sealing ring 22 extends into the first relief groove 11 and is connected to the thin-film capacitor 1, a sealed chamber is formed in the first relief groove 11. The components of the first power module 2 that protrude towards the thin-film capacitor 1 include multiple PIN pins, and the multiple PIN pins divide the sealed chamber into multiple first cooling channels for cooling the first power module 2. When the second sealing ring 32 extends into the second relief groove 12 and is connected to the thin-film capacitor 1, a sealed chamber is formed in the second relief groove 12. The components of the second power module 3 that protrude towards the thin-film capacitor 1 also include multiple PIN pins, and the multiple PIN pins divide the sealed chamber into multiple second cooling channels for cooling the second power module 3.

[0039] In some alternative embodiments, a control board 6 is further included. The control board 6 is located at one end of the thin-film capacitor 1 away from the generator 4. The control board 6 is electrically connected to the first power module 2, the second power module 3, the generator 4, and the drive motor 5. The control board 6 being located at one end of the thin-film capacitor 1 away from the generator 4 can further reduce the volume of the present application, and multiple circuits are integrated at the control board 6 for electrically connecting to the first power module 2, the second power module 3, the generator 4, and the drive motor 5. The user can control the first power module 2, the second power module 3, the generator 4, and the drive motor 5 through the control board 6, thereby improving the convenience for the user.

[0040] In some alternative embodiments, the first three-phase terminal block 21 is provided with three first wiring slots 211, and the second three-phase terminal block 31 is provided with three second wiring slots 311. The generator 4 also has three wiring terminals. The sizes of the three first wiring slots 211 are adapted to the wiring terminals of the generator 4, so as to facilitate the connection between the first three-phase terminal block 21 and the generator 4. The arrangement of the three first wiring slots 211 can separate the three wiring terminals of the generator 4 to avoid interference between the three wiring terminals of the generator 4. The drive motor 5 has three wiring terminals. The sizes of the three second wiring slots 311 are adapted to the wiring terminals of the drive motor 5, so as to facilitate the connection between the second three-phase terminal block 31 and the drive motor 5. The arrangement of the three second wiring slots 311 can separate the three wiring terminals of the drive motor 5 to avoid interference between the three wiring terminals of the drive motor 5.

[0041] Furthermore, the depths of the three first wiring slots 211 increase in sequence. The increasing direction can be from top to bottom or from bottom to top, and the present application does not limit this. The different depth settings of the three first wiring slots 211 can further separate the three wiring terminals of the generator 4 and further avoid interference between the three wiring terminals of the generator 4.

[0042] The depths of the three second wiring slots 311 increase in sequence. The increasing direction can be from top to bottom or from bottom to top, and the present application does not limit this. The different depth settings of the three second wiring slots 311 can further separate the three wiring terminals of the drive motor 5 and further avoid interference between the three wiring terminals of the generator 4.

[0043] In some alternative embodiments, the three first wiring slots 211 have different colors, and the three second wiring slots 311 have different colors. During installation, the user can distinguish the connection positions of the three first wiring slots 211 and the connection terminals of the generator 4 according to different colors, and distinguish the connection positions of the three second wiring slots 311 and the connection terminals of the drive motor 5, thereby improving the convenience of installing the first three-phase wiring base 21 and the generator 4, and improving the convenience of installing the second three-phase wiring base 31 and the drive motor 5. For example, one of the first wiring slots 211 is red, one of the first wiring slots 211 is green, and the other first wiring slot 211 is yellow; one of the second wiring slots 311 is red, one of the second wiring slots 311 is green, and the other second wiring slot 311 is yellow. The specific colors are not limited in this application and can be set according to specific circumstances.

[0044] To further improve the convenience of installing the first three-phase wiring base 21 and the generator 4, the colors of the three first wiring slots 211 respectively correspond to the colors of the three connection terminals of the generator 4. To further improve the convenience of installing the second three-phase wiring base 31 and the drive motor 5, the colors of the three second wiring slots 311 respectively correspond to the colors of the three connection terminals of the drive motor 5.
