Description

Thermal management system for electric motorcycle, thermal management module and electric motorcycle Technical Field

[0001] The present disclosure relates to the field of motorcycles, and in particular to a thermal management system, a thermal management module 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 motorcycles, especially electric motorcycles, achieve increasingly advanced performance, the requirements for thermal management are rapidly increasing. In related technologies, thermal management components are typically distributed across the motorcycle body, with external piping and wiring providing fluid and electrical connections between these components.

[0004] However, adopting this decentralized thermal management system may have the following problems: First, these decentralized components need to occupy different locations in the vehicle's interior, which will lead to lower utilization of the already limited interior space. Second, the need to arrange pipes and wires connecting these components may also increase the complexity of the vehicle's layout and installation, and the body integration is relatively low. In addition, as the length of the fluid pipeline increases, on the one hand, the internal flow resistance will also increase, so a fluid pump that can provide greater power may be required. On the other hand, the increase in flow distance leads to relatively poor thermal management effect, which also makes the energy utilization of the entire system low, and the motorcycle's endurance may also be poor.

[0005] Summary of the Invention

[0006] One of the objectives of the present disclosure is to provide a thermal management 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 thermal management system for an electric motorcycle. The thermal management system includes a base plate, a motor thermal management circuit, a battery thermal management circuit, and electrical circuitry. The motor thermal management circuit includes the electric motorcycle's motor and motor piping, wherein the motor piping is fluidically connected to the motor and includes a first fluid for cooling and / or heating the motor. The battery thermal management circuit includes the electric motorcycle's battery and battery piping, wherein the battery piping is fluidically connected to the battery and includes a second fluid for cooling and / or heating the battery. The electrical circuitry is used to electrically connect the motor, the battery, the motor thermal management circuit, and the battery thermal management circuit. The motor piping, the battery piping, and the electrical circuitry are all located on the base plate. By integrating both the piping and the electrical circuitry onto the base plate, the thermal management system according to the present disclosure can achieve an integrated thermal management design for the electric motorcycle, which at least simplifies the installation of the thermal management system and improves the internal space utilization of the electric motorcycle.

[0008] A second aspect of the present disclosure provides a thermal management module for an electric motorcycle. The thermal management module comprises a housing, a motor conduit, a battery conduit, and electrical wiring. The motor conduit is configured to fluidically connect to the electric motorcycle's motor and includes a first fluid for cooling and / or heating the motor; the battery conduit is configured to fluidically connect to the electric motorcycle's battery and includes a second fluid for cooling and / or heating the battery; and the electrical wiring is configured to electrically connect the thermal management module. The motor conduit, battery conduit, and electrical wiring are all located within the housing. By integrating the motor conduit, battery conduit, and electrical wiring within the module's housing, the thermal management module according to the present disclosure achieves an integrated thermal management design for an electric motorcycle. Furthermore, the thermal management module can be installed by directly plugging it into the motorcycle's battery and / or motor, eliminating the need for fluid conduits or electrical wiring between them. This simplifies installation and reduces fluid flow resistance, while also improving space utilization and thermal management effectiveness within the motorcycle.

[0009] A third aspect of the present disclosure provides an electric motorcycle comprising the aforementioned thermal management system and / or thermal management module, such as a motorcycle solely powered by electricity, or a pure electric motorcycle. The electric motorcycle according to the present disclosure can be adapted with an integrated thermal management system or integrated thermal management module, thereby simplifying and reducing the installation process and difficulty of the motorcycle and improving internal space utilization and thermal management effectiveness.

[0015] 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.

[0016] 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.

[0017] 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 integral; directly or indirectly through an intermediary; fluidically, electrically, or mechanically. Furthermore, in the description of this disclosure, unless otherwise expressly specified or limited, the term "fixed" means connecting or securing several components together according to technical requirements to achieve mechanical assembly while maintaining the correct relative positions and relationships, such as the mechanical connection between a screw and a threaded hole. The term "electrical interface" does not limit the form of an electrical connector, but can be any coupling device that connects electrical terminals to form a circuit. For those skilled in the art, the specific meanings of the above terms in this disclosure can be understood according to specific circumstances.

[0018] 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 "above," "inside," "below," "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 above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein are interpreted accordingly.

[0019] In the relevant technical field, gasoline-powered motorcycles typically only include cooling systems for the engine. In comparison, electric motorcycles need to meet more complex operating conditions and requirements for thermal management of both the motor and battery. Using the cooling system of a gasoline-powered motorcycle for an electric motorcycle may present the following problems: First, the structural design of the engine cooling circuit is generally more complex, and using the engine cooling system for battery or motor cooling may create unnecessary structural redundancy. Second, because the engine of a gasoline-powered motorcycle only operates in an overheated state, its thermal management typically only has cooling functions. However, for electric motorcycles, a thermal management system with both cooling and heating functions may be required. For example, in some situations (e.g., winter or low-temperature conditions), it may be necessary to heat the battery and / or motor to maintain a more suitable operating temperature (e.g., within the range of 0°C to 40°C) and / or the motor (e.g., within the range of -20°C to 85°C).

[0020] In the relevant technical field, the thermal management system of electric vehicles is usually composed of three major systems: the motor cooling system, the battery thermal management system, and the air conditioning system (such as the cabin air conditioning system). If the thermal management system of electric vehicles is used in electric motorcycles, there may be the following problems: First, electric motorcycles do not have air conditioning systems. However, if the air conditioning system is directly omitted, the coupling relationship between the three systems may be destroyed and it will be difficult to adapt to the unique operating conditions of electric motorcycles. Second, because the body frame of a car is much larger than that of a motorcycle, the layout of their internal components, pipes, and lines is also quite different. Compared with the internal space of a car body that has enough space to layout the thermal management system, the thermal management system of an electric motorcycle not only needs to be able to omit the active air cooling module (such as the air conditioning system), but also needs to meet the requirements of higher space utilization, so as to still achieve the thermal management effect of the battery and motor in the relatively limited space inside the body.

[0021] Based on this, the thermal management design of electric motorcycles needs to meet the working conditions and thermal management requirements that are specific to electric motorcycles, which are different from those of fuel motorcycles and electric vehicles. To this end, the thermal management system or thermal management module for electric motorcycles provided by the present disclosure adopts an integrated thermal management arrangement. In a preferred embodiment, all components of the thermal management system except the battery and the motor can be integrated onto the substrate and constituted as a thermal management module. Here, all pipes and wires can be integrated and built into the interior of the thermal management module, battery and motor. By directly plugging and docking the fluid interface and the electrical interface, the thermal management module can be connected to the battery and / or motor, thereby completing the assembly of the thermal management system. In this way, the thermal management system or thermal management module is highly integrated, thereby making full use of the internal space of the electric motorcycle and reducing the complexity of installation.

[0022] Embodiments of the present disclosure are described below with reference to the accompanying exemplary drawings.

[0023] Figure 1 shows a thermal management system 1000 for an electric motorcycle according to one embodiment of the present disclosure. The electric motorcycle can be powered purely electrically or by a combination of electricity and fuel. Thermal management system 1000 may include a substrate 1100, a motor thermal management circuit 1200, a battery thermal management circuit 1300, and electrical circuitry.

[0024] Here, the motor thermal management loop 1200 can be formed by fluidly connecting a motor conduit 1210 with a motor 1220, and a first fluid 1230 for cooling and / or heating the motor can be provided therein. Similarly, the battery thermal management loop 1300 can be formed by fluidly connecting a battery conduit 1310 with a battery 1320, and a second fluid 1330 for cooling and / or heating the battery can be provided therein. It should be understood that the conduit can be any connector capable of fluid transport, such as a hose or tube connecting various components, preferably a rubber tube, nylon tube, plastic tube, metal tube, or other tubular member that achieves the above functions. It should be understood that the fluid can be any substance capable of heat exchange, such as gas, water, ethanol, glycerin, ethylene glycol, mixtures of the foregoing substances, or other substances that achieve the above functions. Preferably, the first fluid and the second fluid can be the same or different fluid media (e.g., coolant), and at least one of them can be a fluid medium that has both cooling and heating functions.

[0025] Here, electrical circuits are used to electrically connect the thermal management system 1000, for example, to electrically connect the thermal management system's substrate 1100, battery thermal management circuit 1300, motor thermal management circuit 1200, and other components. In other words, electrical circuits can be used to electrically connect all or part of a thermal management system or thermal management module. Within the scope of this disclosure, an electrical circuit can be any electrical component that can electrically connect or transmit current between electrical devices, such as wires, printed circuit boards, or other electrical components that achieve these functions.

[0026] Advantageously, the motor pipeline 1210, the battery pipeline 1310 and the electrical circuit are all integrated on a substrate 1100 of the thermal management system. Here, the substrate can be any carrier that can integrate electrical circuits and fluid pipelines. In the thermal management system 1000, all pipelines or electrical circuits for fluid connection or electrical connection are either provided on the substrate or in the housing, or provided inside the motor or battery, and no fluid pipelines or electrical circuits are provided outside or between these components (on the substrate or in the housing, motor and battery). Therefore, the thermal management system or thermal management module according to the present disclosure does not require separate installation of pipelines or electrical circuits, which can reduce the difficulty and complexity of installation of the electric motorcycle.

[0027] Furthermore, the motor thermal management circuit 1200 may further include a motor heat sink 1240, a first fluid storage tank 1250, and a first fluid pump 1260. Advantageously, these components may also be mounted on the base plate 1100 (e.g., via screw connections) and fluidically connected to one another via the motor conduit 1210. Similarly, the battery thermal management circuit 1300 may further include a battery heat sink 1340, a second fluid storage tank 1350, and a second fluid pump 1360. Advantageously, these components may also be mounted on the base plate 1100 (e.g., via screw connections) and fluidically connected to one another via the battery conduit 1310.

[0028] In a preferred embodiment, the battery thermal management circuit 1300 may further include a semiconductor cooling chip 1390. The semiconductor cooling chip may be mounted on the substrate 1100, for example, by screw connections, and electrically connected via electrical wiring. Preferably, when a forward current is passed, the semiconductor cooling chip can be used for heating, for example, indirectly heating the battery via a second fluid and / or directly heating the battery, while when a reverse current is passed, the semiconductor cooling chip can be used for cooling, for example, indirectly cooling the battery via a second fluid and / or directly cooling the battery. Preferably, the opening or closing of the semiconductor cooling chip and the direction of the current flow can be controlled by a controller.

[0029] Within the scope of this disclosure, a heat sink can be any device that uses a thermally conductive material and a heat transfer medium and transfers heat from a heat source to the environment, for example, through a surface. Examples include aluminum alloy heat sinks, copper heat sinks, or other devices that achieve the aforementioned functions. It should be understood that the battery heat sink 1340 and the motor heat sink 1240 can be removably mounted to the baseplate via threaded connections, keyed connections, rivet connections, or can also be non-removably mounted to the baseplate via welding connections. Within the scope of this disclosure, a fluid storage tank can be any open or closed box capable of storing fluid. Within the scope of this disclosure, a fluid pump can be any device capable of transporting or pressurizing a fluid using energy such as electricity or mechanical energy, preferably an electronic pump. Preferably, the opening and closing of the first and second fluid pumps and the flow rate can be controlled by a controller to accommodate different thermal management requirements. Furthermore, all fluid connections within the baseplate can be sealed using sealing methods such as rubber seals.

[0030] In a preferred embodiment, as shown in FIG1 , the thermal management system may further include a circulation loop 1500 connected between the motor thermal management loop 1200 and the battery thermal management loop 1300 . Circulation loop 1500 can be used to control the connectivity between the different thermal management loops to facilitate fluid exchange. For example, when the battery temperature is low, heat dissipated by the motor can be used to heat the battery (or vice versa) through fluid exchange, thereby reducing system energy consumption.

[0031] The circulation loop 1500 may further include a first circulation pump 1520 disposed within the first fluid storage tank 1250, a second circulation pump 1530 disposed within the second fluid storage tank 1350, and a circulation line 1510. The circulation line 1510 is used to fluidically connect the first circulation pump 1520 with the second fluid storage tank 1350, and to fluidically connect the second circulation pump 1530 with the first fluid storage tank 1250. Preferably, the circulation loop can have at least a closed state and an open state. When the circulation loop is in the closed state, the first fluid storage tank 1250 and the second fluid storage tank 1350 are separated, and the first and second fluids therein do not flow into each other (i.e., the first and second fluids circulate in their respective circuits, and fluid from one circuit does not flow into the other circuit). This allows the motor thermal management circuit and the battery thermal management circuit to operate independently of each other. When the circulation loop is in an open state, the first fluid storage tank 1250 and the second fluid storage tank 1350 can be connected through a circulation pipeline, so that the first fluid and the second fluid can circulate with each other (that is, the first fluid and the second fluid can flow from one loop into the other loop), and at least one of the first circulation pump 1520 and the second circulation pump 1530 can provide fluid power to enable the motor thermal management loop and the battery thermal management loop to circulate with each other and realize heat exchange.

[0032] The thermal management system 1000 may also include a controller for controlling the on / off state or flow rate of the first and second circulation pumps, thereby controlling whether the first and second fluids circulate in the motor thermal management circuit and the battery thermal management circuit, and the amount of the fluids circulated. Specifically, temperature sensors 1296 and 1396 may be used to monitor the battery and motor temperatures in real time or sporadically. When the battery temperature is detected to be below a preset battery low-temperature threshold (e.g., within the range of -10°C to 10°C, preferably -5°C to 5°C, and preferably 0°C) and the motor temperature is higher than the battery temperature (e.g., in winter or when the motorcycle's ambient temperature is low), the controller may issue a control signal to activate the first and second circulation pumps, thereby opening the circulation circuits and enabling heat exchange between the battery thermal management circuit and the motor thermal management circuit. This allows the motor's heat to be used to heat the battery, fully utilizing the motor's heat while preventing operational failures when the battery is at low temperatures. It is contemplated that, if necessary, the battery's heat could be used to heat the motor in a similar manner. The controller can also be used to control the opening or closing of the semiconductor refrigeration chip 1390 and the direction of the current. For example, when the battery temperature is lower than a preset battery low temperature threshold, the controller sends a control signal to turn on the semiconductor refrigeration chip and the current is in the forward direction, thereby the semiconductor refrigeration chip can heat the fluid in the battery pipeline to indirectly heat the battery, or can directly heat the battery; when the battery temperature is greater than a preset battery high temperature threshold (for example, in the range of 35°C to 55°C, preferably in the range of 40°C to 45°C, and particularly preferably 40°C), the controller can send a control signal to reverse the current of the semiconductor refrigeration chip, thereby the semiconductor refrigeration chip can cool the fluid in the battery pipeline to indirectly cool the battery, or can directly cool the battery; when the battery temperature is greater than the preset battery low temperature threshold and less than the preset battery high temperature threshold, the controller sends a control signal to turn off the semiconductor refrigeration chip.

[0033] FIG2 exemplarily illustrates a thermal management module according to an embodiment of the present disclosure. It should be understood that the thermal management module 2000 can be configured as part of the thermal management system 1000, for example, including the remaining components other than the battery and the motor. Therefore, the solution described in the present disclosure regarding the thermal management system (for example, with the aid of FIG1 ) can also be adaptively applied to the thermal management module, and vice versa. The content already described in detail above will not be repeated.

[0034] As shown in Figure 2, thermal management module 2000 may include a housing, motor circuit 1210, battery circuit 1310, and electrical circuits. A first fluid 1230 and a second fluid 1330 flow through motor circuit 1210 and battery circuit 1310, respectively. Within the scope of this disclosure, the housing may be understood as any supporting component that replaces or is additional to substrate 1100. Therefore, the components previously integrated on substrate 1100 may also be arranged within the housing, either in place of or in addition to the housing, thereby similarly or further enhancing the module's integration.

[0035] Here, the first fluid tank 1250 and the second fluid tank 1350 provide sufficient storage space for the first and second fluids, respectively. Preferably, the first and second fluid tanks 1250, 1350 are located above the thermal management module and are provided with tank filler ports 1251 and 1351, respectively, for injecting the first and second fluids. This allows the user to conveniently open the tank filler port located at the top of the thermal management module without having to access other components. Alternatively, the first and second fluid tanks 1250, 1350 may be configured as two separate tanks. To maximize vehicle interior space, the two tanks may be designed to be of the same or similar size and shape and arranged side by side above the thermal management module. Alternatively, the first and second fluid tanks 1250, 1350 may be constructed in a single tank, divided into two compartments by a partition disposed in the middle of the tank, thereby forming the first and second fluid tanks 1250, 1350.

[0036] Here, the first fluid pump 1260 and the second fluid pump 1360 can be used to provide power for the fluid, causing the first fluid 1230 and the second fluid 1330 to flow in the motor thermal management circuit 1200 and the battery thermal management circuit 1300, respectively, thereby achieving a thermal management effect. Preferably, the first fluid pump 1260 and the second fluid pump 1360 can be electronic pumps, which may include an electrical plug and a pump fluid interface. For ease of installation, the electrical plug and the pump fluid interface are preferably located on the same side of the electronic pump. Accordingly, the base plate may be provided with an electrical socket, a fluid inlet, and a fluid outlet corresponding to the position of the electronic pump. The electrical plug of the electronic pump and the electrical socket on the base plate can be plugged together to achieve an electrical connection to the electronic pump, and the pump fluid interface of the electronic pump can be plugged together to achieve a fluid connection to the fluid inlet and fluid outlet on the base plate. In addition, the electronic pump can be assembled to the base plate using a removable structure, such as a screw and a screw hole. To enhance fluid sealing, the use of sealing members such as rubber sealing rings at the pump fluid interface can also be considered.

[0037] Here, the motor conduit 1210 can be fluidically connected to other components of the motor thermal management circuit 1200 via the shortest lateral and / or longitudinal path from the first fluid inlet 1271, thereby reducing flow resistance and lowering the power demand on the fluid pump. At the motor heat sink 1240, the motor conduit 1210 can be arranged in an S-shape to ensure sufficient heat exchange between the first fluid in the motor conduit and the motor heat sink. The first fluid ultimately flows along the motor conduit to the first fluid outlet 1272, exiting the thermal management module and flowing into a fluid conduit located within the motor or battery, which is directly plugged into the thermal management module.

[0038] Here, the battery line 1310 can be fluidically connected to other components of the battery thermal management circuit 1300 via the shortest path in the horizontal and / or vertical directions from the second fluid inlet 1371, thereby reducing flow resistance and lowering the power demand on the fluid pump. At the battery heat sink 1300, the battery line 1310 can be arranged in an S-shape to allow for more complete heat exchange between the second fluid in the battery line and the battery heat sink. The second fluid ultimately flows along the battery line 1310 to the second fluid outlet 1372, thereby leaving the thermal management module and flowing to a fluid pipeline directly connected to the thermal management module and disposed inside the motor or battery.

[0039] In a preferred embodiment, the battery circuit 1310 can be arranged in an S-shape at the semiconductor cooling plate 1390 to enable sufficient heat exchange between the second fluid in the battery circuit and the semiconductor cooling plate. The semiconductor cooling plate can be arranged in the lower half of the substrate (e.g., the bottom area) and can at least partially overlap with the battery circuit 1310. It should be understood that the position of the semiconductor cooling plate on the substrate is not limited and can be adjusted accordingly based on the position of the battery or battery circuit, as long as it can partially cover the battery circuit and / or battery, and preferably does not cover any motor circuits.

[0040] Figure 3 shows an exemplary layout of thermal management module 2000. In this example, first and second fluid storage tanks 1250 and 1350 are arranged side by side at the top of the thermal management module. First and second fluid pumps 1260 and 1360 are located on either side of the thermal management module, respectively. Motor heat sink 1240 and battery heat sink 1340 are arranged sequentially from top to bottom in the center of the baseplate. This layout minimizes the fluid and electrical connections between components, reducing flow resistance and electrical wiring complexity.

[0041] Preferably, liquid level sensors 1280 and 1380 may be provided in the first fluid storage tank 1250 and the second fluid storage tank 1350, respectively. Liquid level sensors 1280 and 1380 may be electrically connected via electrical circuits and used to detect the fluid levels in the first and second fluid storage tanks 1250 and 1350 in real time or at irregular intervals. Upon detecting that the fluid levels in the fluid storage tanks fall below a preset threshold, a reminder to the user to add fluid may be issued, thereby immediately preventing the thermal management system and / or thermal management module from malfunctioning due to insufficient fluid.

[0042] In addition, the thermal management module 2000 may also include fans 1130, for example, six to eight fans. These fans 1130 are electrically connected through electrical circuits and are preferably arranged laterally on one side of the motor heat sink and / or the battery heat sink, so that the airflow output from the fan can cool the surface of the heat sink. The lateral installation of the fan is also beneficial to prevent mud and other debris that may splash into the motorcycle when it is moving from adhering to the fan. It should be understood that the fan can be arranged on any side of the motor heat sink or the battery heat sink, or on one side of the motor heat sink and the battery heat sink at the same time. In addition, the number and position of the fans can be flexibly adjusted according to actual needs. Preferably, the operation of the fan can also be controlled by a controller according to usage requirements. For example, when the battery temperature is higher than a preset battery high temperature threshold (e.g., within the range of 35°C to 55°C, preferably within the range of 40°C to 45°C, and particularly preferably 40°C) or the motor temperature is higher than a preset motor high temperature threshold (e.g., within the range of 55°C to 100°C, preferably within the range of 75°C to 95°C, and particularly preferably 85°C), the controller may issue a control signal to operate the fan. It should be understood that the fan control signal is not necessarily limited to the battery temperature or the motor temperature. For example, a fan mounted on one side of the battery heat dissipation device may operate when the battery temperature is higher than a preset high temperature threshold, while a fan mounted on one side of the motor heat dissipation device may operate when the motor temperature is higher than a preset high temperature threshold.

[0043] Figure 4 illustrates an exemplary fluid interface and electrical interface of thermal management module 2000. As described above, thermal management module 2000 includes a first fluid interface, a second fluid interface, and an electrical interface. The first fluid interface may include a first fluid inlet and a first fluid outlet, while the second fluid interface may include a second fluid inlet and a second fluid outlet. In a preferred embodiment, all or a portion of the first fluid inlet, first fluid outlet, second fluid inlet, second fluid outlet, and electrical interface 1410 may be provided within a single connector interface. This allows for simultaneous fluid and electrical connections within the thermal management module, or for simultaneous fluid connections between the battery thermal management circuit and the motor thermal management circuit, through a single connector interface.

[0044] Preferably, the first fluid inlet 1271 , the first fluid outlet 1272 , the second fluid outlet 1372 and the electrical interface 1410 may be collectively constituted in one connector interface 1120 , while the second fluid inlet 1371 is disposed outside the connector interface 1120 .

[0045] In connector interface 1120, first fluid inlet 1271 and first fluid outlet 1272 are arranged side by side at the upper portion of the connector interface, second fluid outlet 1272 is arranged in the middle portion of the connector interface, and electrical interface 1410 is arranged at the lower portion of the connector interface. It should be understood that the layout of first fluid inlet 1271, first fluid outlet 1272, second fluid outlet 1372, and electrical interface 1410 within the thermal management module is not limited to the aforementioned arrangement; rather, the number and arrangement of interfaces within connector interface 1120 can be adjusted based on the needs of pipelines and electrical circuits, or based on corresponding interfaces on batteries or motors.

[0046] Here, the first fluid interface 1270 can be directly plugged into the fluid interface of the battery 1320 and / or the motor 1220, thereby achieving a fluid connection between the motor pipeline and the internal pipeline of the motor and / or the battery without the need for other fluid pipelines therebetween.
