Abstract
Description
Technical Field
[0001] This application relates to the field of automotive manufacturing technology, and more specifically, to a motor controller and a hybrid power system. Background Technology
[0002] With the escalating global energy crisis and environmental pollution, the automotive industry is facing an urgent need for energy conservation and emission reduction. Traditional gasoline-powered vehicles, due to their high energy consumption and emissions, can no longer meet the requirements of sustainable development. Meanwhile, pure electric vehicles are limited by battery technology bottlenecks, resulting in problems such as short driving range, long charging times, high costs, and performance degradation at low temperatures. Against this backdrop, hybrid power systems, as a transitional technology, have become an important solution for achieving energy conservation and emission reduction by combining the advantages of internal combustion engines and electric motors. Currently, most four-wheel drive hybrid systems use high-voltage distribution boxes to distribute power between high-voltage electrical components and to house related electrical fuses.
[0003] In traditional hybrid power system layouts, multiple fuse structures occupy the high-voltage distribution box area, resulting in insufficient layout space. At the same time, the connection of the fuse structures generates multiple wiring harnesses with diverse routing, making the power distribution method more complex and increasing research and development costs.

[0023] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.
[0025] The following reference Figures 1 to 4 This application describes a hybrid power system provided according to some embodiments.
[0026] like Figure 1 , Figure 3 As shown, a motor controller and a hybrid power system provided according to some embodiments of this application are provided, wherein the hybrid power system includes a motor controller (MCU) 100; wherein the motor controller 100 includes a housing 110 having a receiving cavity; a first fuse 130 disposed within the receiving cavity; and an external interface 120 disposed on the housing 110 and communicating with the receiving cavity, the external interface 120 including a first input connector and a first output connector, the first fuse 130 being connected to the first input connector and the first output connector, the first input connector and the first output connector being capable of being connected in series with a heater (PTC) 131;
[0027] In this embodiment, the motor controller 100 has an internal cavity. The first fuse 130 is the fuse for the heater 131, which is used to provide heating. The first fuse 130 is located inside the cavity of the motor controller 100, avoiding the need for a separate fuse box for the heater 131, which would result in insufficient space inside the high-voltage distribution box of the hybrid power system. Furthermore, a separate fuse box would increase the number of wiring harnesses and connection points. By integrating the fuse of the heater 131 into the motor controller 100, the number of wiring harness connections is reduced, lowering the cost of the wiring harnesses and simplifying their arrangement and management. This also saves space resources within the high-voltage distribution box, improving the utilization rate of the layout space. The first fuse 130 provides overcurrent protection for the heater 131 and the first input and first output connectors of the external interface 120. When an overcurrent occurs in the circuit, the first fuse 130 melts and cuts off the circuit, preventing equipment damage or safety accidents caused by overcurrent, thus improving the safety and reliability of the system.
[0028] In some possible embodiments, such as Figure 1 , Figure 3 As shown, the motor controller 100 also includes a second fuse 140 disposed in the receiving cavity; the external interface 120 also includes a second input connector and a second output connector, the second fuse 140 is connected to the second input connector and the second output connector, and the second input connector and the second output connector can be connected in series with the high-pressure electric compressor (A / C) 141 of the hybrid power system.
[0029] In this embodiment, the high-pressure electric compressor 141 is used to realize the refrigeration function. The second fuse 140 serves as a protection device for the high-pressure electric compressor 141. The second fuse 140 provides overcurrent protection for the high-pressure electric compressor 141 and the second input and second output connectors of the external interface 120. It can melt in time when an abnormal situation of overcurrent or short circuit occurs in the circuit, thereby quickly isolating the faulty part from the system, preventing the fault from expanding, and reducing the impact on the entire system. Integrating the second fuse 140 into the motor controller 100 avoids the need to set up a separate fuse box for the high-pressure electric compressor 141, saves electrical connection points and wiring harnesses in the system, reduces problems caused by poor wiring harness connection or faults, and reduces the material and installation costs of the wiring harness.
[0030] In some possible embodiments, such as Figure 1 As shown, the external interface 120 is located on the long side of the housing 110; the first fuse 130 and the second fuse 140 are arranged side by side along the length of the housing 110 in the receiving cavity.
[0031] In this embodiment, the external interface 120 is located on the long side of the housing 110, which makes it easier for users to access and operate the interface when connecting external devices, thus improving the ease of use.
[0032] In some possible embodiments, such as Figure 1 As shown, the motor controller 100 also includes a first high-voltage output interface 212. The first high-voltage output interface 212 is disposed on the housing 110 of the motor controller 100, avoiding the external interface 120. The first high-voltage output interface 212 is used to connect in series with the power battery 200 of the hybrid power system.
[0033] In this embodiment, the first high-voltage output interface 212 is positioned to avoid the external interface 120, thus separating them spatially and facilitating heat dissipation in the interface area.
[0034] In some possible embodiments, such as Figure 2 , Figure 4 As shown, the hybrid power system also includes a power battery 200; a first fuse socket 210 disposed on the casing of the power battery 200; a first high-voltage input interface 211 connected to the first fuse socket 210, the first high-voltage input interface 211 connected to the first high-voltage output interface 212, and the first high-voltage input interface 211, the first high-voltage output interface 212 and the first fuse socket 210 connected in series.
[0035] In this embodiment, when the internal space of the motor controller 100 is insufficient to accommodate its own fuse, the power battery 200 is used to add a fuse socket to protect the motor controller 100. This avoids the need for an additional fuse device in the motor controller 100. Specifically, the first high-voltage output interface 212 of the motor controller 100 is connected to the first high-voltage input interface 211 of the power battery 200 using a wiring harness. The first high-voltage input interface 211 is connected to the first fuse socket 210, forming a series circuit. When a fault occurs in the circuit of the motor controller 100, causing excessive current, the fuse in the fuse socket blows, thereby cutting off the circuit and preventing interference with the normal operation of the power battery 200. By centrally placing the fuse in the power battery 200, the spatial layout of the high-voltage electrical system can be better planned, reducing the confusion of wiring intersections and improving space utilization. Furthermore, the integrated fuse socket reduces the overall size of the equipment compared to setting up independent fuses, and the installation and replacement of the fuse socket are more convenient and quick.
[0036] In some possible embodiments, such as Figure 4As shown, the power battery 200 also includes a second fuse socket 220, which is disposed on the casing of the power battery 200; a second high-voltage input interface, which is connected to the second fuse socket 220, and the second high-voltage input interface is used to connect to the second high-voltage output interface of the drive motor 221 of the hybrid power system. The second high-voltage input interface, the second high-voltage output interface, and the second fuse socket 220 are connected in series.
[0037] In this embodiment, when the internal space of the drive motor 221 is insufficient to accommodate its own fuse, the power battery 200 is used to add a fuse socket to protect the drive motor 221. Specifically, the second high-voltage input interface is connected to the second fuse socket 220, and after the drive motor 221 is connected to the second high-voltage output interface, the second high-voltage input interface is connected to the second high-voltage output interface, forming a series circuit. In the series circuit, the current passes sequentially through the second high-voltage output interface, the second high-voltage input interface, and the second fuse socket 220 of the drive motor 221. When an overcurrent or short circuit occurs in the circuit, the fuse in the second fuse socket 220 will melt, thereby cutting off the circuit and providing protection. By placing the second fuse socket 220 on the casing of the power battery 200, the fuse device is centrally located, reducing the space occupied by the fuse device inside the vehicle, making the vehicle's internal layout more compact and reasonable, reducing wiring branches, simplifying the wiring layout, and reducing the probability of failure.
[0038] This motor controller and hybrid power system centralizes the fuses for the heater 131 and the high-voltage electric compressor 141 within the motor controller 100. Specifically, the first fuse 130 and the second fuse 140 are located within the motor controller 100. The first fuse 130 is connected to the first output connector and the first input connector, which in turn are connected to the heater 131 in series. Similarly, the second fuse 140 is connected to the second output connector and the second input connector, which in turn are connected to the high-voltage electric compressor 141 in series. Thus, the first fuse 130 acts as a protection device for the heater 131, and the second fuse 140 acts as a protection device for the high-voltage electric compressor 141. These fuses can promptly melt and disconnect the circuit in case of overcurrent or short circuit, preventing damage to the heater 131 and the high-voltage electric compressor 141 due to overcurrent, thus saving internal space in the high-voltage distribution box. Furthermore, when the internal space of the motor controller 100 and the drive motor 221 is insufficient to accommodate their respective components... In case of a short circuit, two additional fuse sockets are added via the power battery 200 to protect the motor controller 100 and the drive motor 221. The motor controller 100, the first high-voltage output interface 212, the first high-voltage input interface 211, the first fuse socket 210, and the power battery 200 are connected in series to form a series circuit. This allows the first fuse socket 210 to protect the motor controller 100. When a fault occurs in the circuit of the motor controller 100, the fuse in the first fuse socket 210 blows, cutting off power to the motor controller 100. Simultaneously, the drive motor 221, the second high-voltage output interface, the second high-voltage input interface, the second fuse socket 220, and the power battery 200 are connected in series to form a series circuit. This allows the second fuse socket 220 to provide short-circuit protection for the drive motor 221. If an overvoltage occurs in the circuit of the drive motor 221, causing excessive current, the fuse in the second fuse socket 220 will blow, cutting off the circuit and preventing the short-circuit current from generating high temperatures that could lead to fires or other safety accidents. The fuse sockets also facilitate future maintenance and replacement by personnel.
