Description

Power system for electric motorcycle and electric motorcycle Technical Field

[0001] The present disclosure relates to the field of motorcycles, and in particular to a power system of an electric motorcycle and an electric motorcycle. Background Art

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] As the performance and features of motorcycles, especially electric motorcycles, continue to improve, the user base is also increasingly demanding higher power and features. Consequently, demand for high-power, compact models is also growing. In related technologies, the electrical connections of electric motorcycle powertrains typically utilize cables. Specifically, the battery, motor, and controller of an electric motorcycle are dispersed across the motorcycle body, and these components are electrically and fluidically connected to each other via external electrical cables and fluid pipelines.

[0004] However, the following problems may arise with this type of cable connection solution: First, these dispersed components require a large amount of space inside the vehicle, which will result in even lower utilization of the already limited interior space. Second, the need to arrange electrical cables and fluid pipelines connecting these components increases the complexity of in-vehicle layout and installation, and the vehicle body integration is relatively low. Furthermore, under non-human external forces such as vibration or accidents, these external electrical cables and fluid pipelines may have poor shock resistance, waterproofness, and dustproofness. In addition, a large number of complex electrical cables and fluid pipelines may also increase the weight of the entire vehicle, which also causes the motorcycle to consume more energy during driving and thus reduce its endurance.

[0005] Summary of the Invention

[0006] One of the objectives of the present disclosure is to provide a power system for an electric motorcycle that can at least partially address the above-mentioned issues. This objective can be achieved through the following technical solutions:

[0007] A first aspect of the present disclosure provides a power system for an electric motorcycle, comprising a battery, a motor, and a controller. The battery comprises a first battery connector and a second battery connector, and the first and second battery connectors are disposed on different sides of the battery. The motor comprises a motor connector, and the controller comprises a controller connector. The battery and the motor can be electrically connected by plugging the first battery connector into the motor connector, and the battery and the controller can be electrically connected by plugging the second battery connector into the control connector. By integrating the battery, motor, and controller into an integrated power system using a plug-in connection, the power system according to the present disclosure can, for example, achieve a modular system design for an electric motorcycle, which can at least simplify the installation of the power system and improve the internal space utilization of the electric motorcycle. Furthermore, the plug-in connection can eliminate electrical cables or fluid lines between the components, thereby reducing vehicle weight and driving instability. This can, for example, improve the electric motorcycle's endurance and anti-interference capabilities.

[0008] A second aspect of the present disclosure provides an electric motorcycle including the aforementioned power system. The electric motorcycle is, for example, a motorcycle driven solely by electricity, or a pure electric motorcycle. The electric motorcycle according to the present disclosure can be adapted to an integrated power system, thereby simplifying the motorcycle's production process, reducing installation complexity, and improving internal space utilization.

[0018] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0019] It should be understood that the terminology used herein is for the purpose of describing specific example embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, as used herein, the expressions "a," "an," and "the" may also be intended to include plural forms. The terms "comprise," "include," and "have" are inclusive and, therefore, specify the presence of the stated features, elements, and / or components, but do not preclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0020] Although the terms "first," "second," and so on may be used herein to describe various elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used solely to distinguish one element, component, region, layer, or section from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and "third," as well as other numerical terms, when used herein, do not imply a sequence or order. Furthermore, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be interpreted broadly, meaning, for example, fixed, removable, or integrally connected; directly or indirectly through an intermediary. Furthermore, in the description of this disclosure, unless otherwise expressly specified or limited, the term "fixed" refers to the process of connecting or securing several components together according to technical requirements, thereby achieving mechanical assembly while maintaining the correct relative positions and relationships, such as the mechanical connection between a screw and a threaded hole. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on the specific circumstances.

[0021] For ease of description, spatially relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figures, such as "upper," "middle," "lower," "inside," "near," etc. Such spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, an element described as "below" or "below" another element or feature would then be oriented as "above" or "above" another element or feature. Thus, the example term "below" may include both upper and lower orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein are interpreted accordingly.

[0022] With the development of new energy motorcycles, consumers are increasingly demanding longer battery life and lighter weight, while manufacturers are also seeking to simplify the production process. For electric motorcycles, the powertrain, primarily consisting of batteries, motors, and controllers, is crucial for providing the vehicle's battery life, electrical performance, and power. For this reason, those skilled in the art are constantly seeking ways to design various powertrain layouts within the vehicle body, optimizing cable connection solutions and improving internal space utilization. This can, for example, improve the electric motorcycle's battery life and anti-interference capabilities, while simplifying the production process.

[0023] However, the inventors of the present disclosure have creatively discovered that the battery, motor and controller can be connected in a plug-in manner (including electrical connection and / or fluid connection), which can at least partially achieve the following technical effects: First, modular connection between various electrical components is achieved by plug-in connection, and the entire power system only needs mechanical fixation to complete the entire installation after plug-in, which can simplify the production or assembly process of the electric motorcycle; second, by placing all electrical cables and fluid pipelines inside each electrical component, external electrical cables and fluid pipelines can be omitted, for example, which not only improves the sealing of the entire power system and achieves better shock resistance, waterproofness and dustproofness, but also reduces the body weight of the electric motorcycle, thereby improving the endurance of the motorcycle; third, through the modular integration of batteries, motors and controllers, the space utilization and functional integration of electric motorcycles can be effectively improved.

[0024] Embodiments of the present disclosure are described below with reference to the accompanying exemplary drawings.

[0025] Figures 1 and 2 illustrate a power system 1000 for an electric motorcycle according to one embodiment of the present disclosure. The electric motorcycle can be a purely electrically powered motorcycle or a hybrid powered motorcycle. The power system 1000 may include a battery 1100, a motor 1200, and a controller 1300. The battery 1100 may be configured as a battery pack and used to provide the energy required by the electric motorcycle. The motor 1200 may be used to convert electrical energy into mechanical energy to drive the electric motorcycle. The controller 1300 may be used to collect various signals from the electric motorcycle's electrical components (e.g., the battery, motor, actuators, and sensors), perform corresponding processing, and output control signals to other electrical components to enable the electric motorcycle to operate normally as intended by the user (e.g., controlling the electric motorcycle's transmission to control gear levels, controlling the electric motorcycle's motor speed to control driving force, etc.). The battery, motor, and controller may constitute at least a portion of the power system, working in conjunction to provide driving force for the electric motorcycle and control its driving state.

[0026] Preferably, the controller can be configured as either a controller that partially integrates vehicle control functions (e.g., a central controller, motor controller, transmission controller, battery management controller, etc.), or a VCU (Vehicle Control Unit) that integrates complete vehicle control functions. This controller can be used to collect input signals from various electrical components and output load control signals to ensure the electric motorcycle operates as intended by the driver. The VCU can also be responsible for functions such as normal driving, brake energy feedback, energy management of the vehicle's drive system and power battery, network management, fault diagnosis and handling, and vehicle status monitoring.

[0027] As shown in FIG2 , connectors may be provided on different sides of the battery 1100, for example, a first battery connector 1110 and a second battery connector 1120. A motor connector 1210 may be provided on the motor 1200, while a controller connector 1310 may be provided on the controller 1300. Here, the first battery connector 1110 and the motor connector 1210 may be directly plugged into each other to achieve an electrical connection between the battery 1100 and the motor 1200. Similarly, the second battery connector 1120 and the controller connector 1310 may be directly plugged into each other to achieve an electrical connection between the battery 1100 and the controller 1300. Here, the motor 1200 and the controller 1300 may also be provided with a plurality of threaded holes, and a plurality of threaded holes may be provided on the battery 1100 at positions corresponding to these threaded holes. By sequentially inserting screws through the threaded holes on the battery, motor, and controller and tightening them therein, both electrical connection and mechanical fixation can be achieved between the battery and the motor, and between the battery and the controller. It should be understood that the mechanical connections between these components can be detachable, non-detachable, or integral. Removable connections include, but are not limited to, threaded connections, snap-fit ​​connections, and hinged connections, while non-detachable connections include, but are not limited to, welding, bonding, and riveting. The fixing method for each connector can be selected based on actual needs and is not necessarily as shown in the accompanying drawings.

[0028] Preferably, the electrical connectors of the battery 1100 for connecting to the motor 1200 can be collectively constituted in the first battery connector 1110, and for example, the electrical cables of the motor 1200 for achieving corresponding connections with the battery 1100 can be collectively constituted in the motor connector 1210. Thus, by directly plugging the first battery connector 1110 and the motor connector 1210, the electrical contacts inside the two connectors can be connected accordingly to achieve electrical connection. Similarly, the electrical connectors of the battery 1100 for connecting to the controller 1300 can be collectively constituted in the second battery connector 1120, and for example, the electrical cables of the controller 1300 for achieving corresponding connections with the battery 1100 can be collectively constituted in the controller connector 1310. Thus, by directly plugging the second battery connector 1120 and the controller connector 1310, the electrical contacts inside the two connectors can be connected accordingly to achieve electrical connection.

[0029] Advantageously, no external electrical cables, i.e., external electrical wires, may be connected between the first battery connector 1110 and the motor connector 1210, or between the second battery connector 1120 and the controller connector 1310, because all electrical connections between the battery and the motor can be integrated into the first battery connector and the motor connector, and all electrical connections between the battery and the controller can also be integrated into the second battery connector and the controller connector. This not only simplifies the cable connection and assembly process of the electric motorcycle, but also helps to improve the shock resistance, waterproofness, and dustproofness of the power system, thereby improving stability during driving. In the scope of this disclosure, an electrical cable can be understood as any physical connecting cable that can achieve electrical connection or transmit current between various electrical devices, such as a copper bus, a wire, a terminal block, etc.

[0030] In a preferred embodiment, the first battery connector 1110 is arranged on the rear side of the battery 1100, and the second battery connector 1120 is arranged on the top side of the battery 1100. Thus, after the assembly of the power system is completed, the rear side may refer to the side of the battery facing away from the windward side of the electric motorcycle, and the top side may refer to the side of the battery farther from the ground in the vertical direction. Thus, the motor 1200 for driving the rear wheel of the electric motorcycle can be correspondingly plugged into the rear side of the battery, which can facilitate the drive connection between the motor 1200 and the rear wheel. The controller is located on the top side of the battery so that it is not affected by other components and can also be symmetrical about the central axis of the electric motorcycle, so that the body is easier to maintain balance and the balance of the electric motorcycle is enhanced.

[0031] Figures 3 and 4 illustrate exemplary structures for connecting a battery to a motor, particularly a first battery connector and a motor connector. In the exemplary embodiment shown in the figures, the first battery connector 1110 may include a first battery connector base 1112 and a first battery connector body 1111 disposed or extending on one or both sides thereof. The first battery connector body may also be provided with a plurality (e.g., two or three) of first battery connector positioning holes 1113. Similarly, the motor connector 1210 may include a motor connector base 1212, a motor connector body 1211 disposed or extending therefrom, and a plurality (e.g., two or three) of motor connector positioning pins 1213. These motor connector positioning pins may extend from the motor connector base 1212 and be arranged on both sides of the motor connector body 1211.

[0032] Advantageously, the first battery connector body 1111 and the motor connector body 1211 can be respectively configured as integrated electrical connectors for achieving electrical connection of the battery and the motor, while the first battery connector base 1112 and the motor connector base 1212 can respectively be configured as the supporting base for all components of the first battery connector and the motor connector and the base or substrate for the plug-in connection between the two. Advantageously, the number and arrangement positions of the motor connector locating pins 1213 correspond to the first battery connector locating holes 1113. Specifically, the first battery connector locating holes 1113 are respectively provided at both ends of the first battery connector body 1111 along the length direction, and motor connector locating pins 1213 are respectively provided on the side of the motor connector base 1212 for plug-in and at the corresponding positions of the two first battery connector locating holes. As a result, the two first battery connector locating holes can cooperate with the two motor connector locating pins 1213, thereby achieving the limitation of the motor connector in the first battery connector.

[0033] Furthermore, a first battery connector sealing ring 1114 is advantageously provided on the first battery connector base 1112, particularly on the side thereof that engages the motor connector base 1212, while a motor connector sealing ring 1214 is provided on the second motor connector body 1211, particularly on the side thereof that engages the first battery connector body 1111 and / or the second motor. Preferably, both the first battery connector sealing ring 1114 and the motor connector sealing ring 1214 are disposed circumferentially on different mating surfaces. This allows for multiple seals between the base first battery connector and the motor connector, forming outer and inner sealing rings between the base and the body, respectively. This multiple seal not only minimizes the gap between the first battery connector and the motor connector, thereby enhancing dust and water resistance during insertion, but also increases relative positional stability between the connectors, thereby ensuring proper functioning of the internal electrical components. In addition, a plurality of threaded holes may be provided at corresponding positions on the first battery connector base 1112 and the motor connector base 1212. By passing screws through the aforementioned threaded holes in sequence, the mechanical connection between the first battery connector 1110 and the motor connector 1210 may be made more firm and stable.

[0034] Figures 5 and 6 illustrate an exemplary structure for connecting a battery to a controller, specifically a second battery connector to a motor. In the exemplary embodiment shown, the second battery connector 1120 may include a second battery connector base 1122 and a second battery connector body 1121 disposed or extending on one or both sides thereof, with multiple (e.g., two or three) second battery connector locating holes 1123 disposed on one or both sides. The controller connector 1310 may include a controller connector base 1312 and a controller connector body 1311 disposed or extending on one or both sides thereof, with multiple (e.g., two or three) controller connector locating pins 1313 disposed on one or both sides. The second battery connector body 1121 and the controller connector body 1311 may respectively constitute integrated electrical connectors for electrically connecting the battery and the motor, while the second battery connector base 1122 and the controller connector base 1312 may respectively constitute the supporting base for all components of the second battery connector and the controller connector, and the base or substrate for their plug-in connection.

[0035] Advantageously, second battery connector locating holes 1123 are provided at both ends of the second battery connector body 1121 along its length, and controller connector locating pins 1313 are provided at corresponding positions of the controller connector base 1312 for engaging the second battery connector locating holes. Thus, the second battery connector locating holes can cooperate with the controller connector locating pins, allowing the controller connector to be inserted and retained in the second battery connector.

[0036] Further advantageously, controller connector 1310 may include a controller connector sealing ring 1314, which may preferably be disposed on a mating surface of controller connector body 1311 for engaging second battery connector body 1121. Furthermore, second battery connector 1120 may include a second battery connector sealing ring 1124, which may preferably be disposed on a mating surface of second battery connector base 1122 for engaging controller connector base 1312 and / or a second battery. In other words, multiple second battery connector sealing rings 1124 may be disposed on opposite surfaces of second battery connector base 1122. Advantageously, both second battery connector sealing rings 1124 and controller connector sealing rings 1314 are circumferentially disposed on different mating surfaces, enabling the mating of the second battery connector and the controller connector to achieve multiple seals, namely, forming outer and inner seals between the bases and between the bodies, respectively. This multiple seal not only minimizes the gap between the second battery connector and the controller connector, thereby enhancing dust and water resistance during insertion, but also increases the relative positional stability of the connectors, ensuring the proper functioning of the internal electrical components. Furthermore, corresponding threaded holes are provided on the second battery connector base 1122 and the controller connector base 1312. Screws passing through these threaded holes provide a more secure and stable connection between the second battery connector 1120 and the controller connector.

[0037] Advantageously, controller connector 1310 may further include controller connector terminals 1315, which may pass through the controller's PCB and be welded to PCB 1320. By welding controller connector 1310 to PCB 1320, the controller can be inseparably fixed together, thereby strengthening both the mechanical and electrical connections between the controller and the battery, thereby preventing the controller from becoming loose due to non-human external forces such as vibration or accidents.

[0038] Figures 7 and 8 respectively show schematic diagrams of a preferred motor connection port and battery connection port of a power system. As shown in the figure, the connection ports of the motor 1200 and the battery 1100 may include a fluid interface and an electrical interface, respectively. Here, the motor fluid interface 1220 may include a motor fluid inlet 1221 and a motor fluid outlet 1222, and they are preferably arranged on the same side of the motor connector 1210 so that the inflow and outflow of fluid can be completed simultaneously through a single plug-in. Similarly, the battery fluid interface may include a battery fluid inlet 1131 and a battery fluid outlet 1132, and they are preferably arranged on the same side of the battery connector 1120 so that the inflow and outflow of fluid can be completed simultaneously through a single (same-side) plug-in. Here, the battery fluid interface 1130 and the motor fluid interface 1220 are arranged at corresponding positions so that the electrical connection of the battery 1100 and the motor 1200 can be achieved by directly plugging the first battery connector 1110 and the motor connector 1210. At this time, for example, a fluid (e.g., coolant) used to cool the motor and / or battery can flow from the fluid conduit within the battery to the fluid conduit within the motor through, for example, the battery fluid outlet 1132 and the motor fluid inlet 1221. Alternatively, it can flow from the fluid conduit within the motor to the fluid conduit within the battery through, for example, the motor fluid outlet 1122 and the battery fluid inlet 1131, thereby forming a circulation flow within the battery and / or motor. Advantageously, the fluid conduit for the motor can pass through the interior of the battery housing to achieve fluid connection with the thermal management system. This arrangement shortens the fluid conduit between the motor and the thermal management system, which not only helps reduce fluid flow resistance and fluid conduit complexity, but also improves space utilization and thermal management effectiveness within the motorcycle.

[0039] In a preferred embodiment, battery 1100 may further include a third battery connector for electrically connecting to the electric motorcycle's thermal management module. Preferably, battery 1100 also includes a battery fluid interface on the same side as the third battery connector, for simultaneously electrically and fluidically connecting battery 1100 to the thermal management module via direct insertion of the third battery connector. This allows the electric motorcycle's powertrain and thermal management system to be integrated, thereby improving the electric motorcycle's functional integration.

[0040] Although the fluid interfaces shown in the figures are all arranged outside the electrical interface, it is conceivable that these fluid interfaces can also be constructed inside the electrical interface, or integrated with the electrical interface in a connector. For example, the battery fluid interface can be constructed in the first battery connector, the second battery connector and / or the third battery connector, and the motor fluid interface can also be constructed in the motor connector. Through this integrated arrangement, the functions of electrical and fluid connection can be integrated into one connector, so that the fluid connection and electrical connection can be completed at the same time by plugging the same connector. It should be understood that the number and arrangement of interfaces inside the connector are not limited to the method described herein, but can be adjusted according to the needs of pipelines and electrical cables or according to the corresponding interfaces on the battery or motor.

[0041] The present disclosure implements an integrated power system for an electric motorcycle through the following implementation schemes.
