Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of motorcycles, in particular to a thermal management system, a thermal management module and an electric motorcycle. BACKGROUND

[0002] The background section provided herein is merely for information and is not necessarily a prior art of the present disclosure.

[0003] With the increasing performance configurations of motorcycles, especially electric motorcycles, the requirements for thermal management of these motorcycles are also rapidly increasing. In the related art, the components for thermal management are usually arranged in different positions of the motorcycle body in a scattered manner, and fluid connection and electrical connection between the components are realized through external pipelines and wires.

[0004] However, the thermal management system with such a scattered arrangement may have the following problems. First, the scattered components need to occupy different internal space positions, which will result in a low utilization rate of the limited internal space. Second, since the pipelines and wires connecting between the components need to be arranged, the complexity of the internal arrangement and installation may also be increased, and the integration of the motorcycle body is relatively low. In addition, with the increase of the length of the fluid pipeline, on the one hand, the internal flow resistance will also increase, so a fluid pump with larger power may be needed, on the other hand, the increase of the flow distance results in a relatively poor thermal management effect, and the energy utilization rate of the whole system is low, so the endurance of the motorcycle may also be poor. SUMMARY

[0005] One of the purposes of the present disclosure is to provide a thermal management system for an electric motorcycle, which can at least partially solve the above problems. The purpose can be achieved by the following technical solutions:

[0006] The first aspect of the present disclosure provides a thermal management system for an electric motorcycle, comprising a substrate, a motor thermal management loop, a battery thermal management loop and an electrical circuit, the motor thermal management loop comprising a motor of the electric motorcycle and a motor circuit, wherein the motor circuit is in fluid connection with the motor and comprises a first fluid for cooling and / or heating the motor, the battery thermal management loop comprising a battery of the electric motorcycle and a battery circuit, wherein the battery circuit is in fluid connection with the battery and comprises a second fluid for cooling and / or heating the battery, the electrical circuit for electrically connecting the motor, the battery, the motor thermal management loop and the battery thermal management loop, wherein the motor circuit, the battery circuit and the electrical circuit are all located on the substrate. By integrating the circuit and the electrical circuit on the substrate, the thermal management system according to the present disclosure can realize 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.

[0007] The second aspect of the present disclosure provides a thermal management module for an electric motorcycle, comprising a housing, a motor circuit, a battery circuit and an electrical circuit, the motor circuit for being in fluid connection with a motor of the electric motorcycle and comprising a first fluid for cooling and / or heating the motor, the battery circuit for being in fluid connection with a battery of the electric motorcycle and comprising a second fluid for cooling and / or heating the battery, the electrical circuit for electrically connecting the thermal management module, wherein the motor circuit, the battery circuit and the electrical circuit are all located inside the housing. By integrating the motor circuit, the battery circuit and the electrical circuit inside the housing of the module, the thermal management module according to the present disclosure can realize an integrated thermal management design for the electric motorcycle, and in addition, the installation of the thermal management module can be completed by directly plugging it to the battery and / or the motor of the motorcycle, without the fluid circuits or the electrical circuits between the module and them. This not only can simplify the installation and reduce the flow resistance of the fluid, but also can improve the internal space utilization and the thermal management effect of the motorcycle.

[0008] The third aspect of the present disclosure provides an electric motorcycle comprising the above-mentioned thermal management system and / or the above-mentioned thermal management module, for example, a motorcycle driven only by electricity, or a pure electric motorcycle. The electric motorcycle according to the present disclosure can be adapted to the integrated thermal management system or the integrated thermal management module, so as to not only simplify the installation process of the motorcycle and reduce the installation difficulty, but also improve the internal space utilization and the thermal management effect of the motorcycle.

[0014] Exemplary embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. While example embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms without being limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0015] It is to be understood that the terms used herein are merely for the purpose of describing particular example embodiments and are by no means intended to be limiting. As used herein, the expressions "a", "an" and "the" can also mean "one or more than one", unless the context clearly dictates otherwise. The terms "includes", "including", and "has" are inclusive and therefore specify the presence of 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.

[0016] Although the terms first, second, etc. can 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 can be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as "first", "second", and "third" and other numerical terms as used herein, are used merely to identify different elements, components, regions, layers or sections, unless the context clearly indicates otherwise. In addition, in the description of the disclosure, unless explicitly stated and limited otherwise, the terms "set", "connected", "coupled" should be understood broadly, for example, can be fixed connection, can also be detachable connection, or integral connection; can be directly connected, or indirectly connected through an intermediate medium; can be fluid connection, or electrical connection or mechanical connection. In addition, in the description of the disclosure, unless explicitly stated and limited otherwise, the term "fixed" means that several components are coupled or fixed according to technical requirements, so as to realize mechanical assembly while maintaining correct relative position and mutual relationship, for example, mechanical connection mode of screw and screw hole. The term "electrical interface" does not limit the form of electrical connector, but can be any coupling device that connects electrical terminals to form an electrical circuit. For those skilled in the art, the specific meaning of the above terms in the disclosure can be understood according to the specific circumstances.

[0017] For ease of description, spatial relative terms can be used herein to describe the relationship of one element or feature to another element or feature as shown in the drawings, such as "upper", "middle", "lower", "inner", "close" and the like. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over, the element described as "below" or "under" the other element or feature will then be oriented "above" or "over" the other element or feature. Therefore, the example term "below" can include both upward and downward orientations. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used herein are interpreted accordingly.

[0018] In the related art, a fuel motorcycle usually only includes a cooling system for the engine. In contrast, an electric motorcycle needs to meet more complex working conditions and requirements for thermal management of the motor and the battery. If the cooling system of the fuel motorcycle is used for the electric motorcycle, the following problems may exist: first, the structural design of the cooling circuit for the engine is usually complex, and using the engine cooling system for the cooling of the battery or the motor may cause unnecessary redundancy in structure; second, since the engine of the fuel motorcycle only has a working state of excessively high temperature, its thermal management usually only has a cooling function, while for the electric motorcycle, a thermal management system that has both cooling and heating functions may be needed. For example, in some cases (e.g., winter or low-temperature state), the battery and / or the motor may also need to be heated to make the battery at a more suitable working temperature (e.g., in the range of 0°C to 40°C) and / or the motor at a suitable working temperature (e.g., in the range of -20°C to 85°C).

[0019] In the related art, the thermal management system of an electric vehicle usually consists of three systems, i.e., a motor cooling system, a battery thermal management system, and an air conditioning system (e.g., a cabin air conditioning system). If the thermal management system of the electric vehicle is used for the electric motorcycle, the following problems may exist: first, the electric motorcycle does not have an air conditioning system, and if the air conditioning system is directly omitted, the coupling relationship of the three systems may be destroyed, and it may be difficult to adapt to the specific working conditions of the electric motorcycle; second, since the body frame of the vehicle is much larger than that of the motorcycle, the layout of the components, pipelines, and lines inside them also has great differences. Compared with the vehicle body, which has enough space for the layout of the thermal management system, the thermal management system of the electric motorcycle not only needs to omit the active air cooling module (e.g., the air conditioning system), but also needs to meet the requirement of higher space utilization, so as to still achieve the thermal management effect of the battery and the motor in the relatively limited space inside the body.

[0020] Therefore, the thermal management design of the electric motorcycle needs to meet the specific working conditions and thermal management requirements of the electric motorcycle that are different from those of the fuel motorcycle and the electric vehicle. To this end, the thermal management system or the thermal management module for the electric motorcycle 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 on a substrate and formed into a thermal management module. Here, all pipelines and wires can be integrally built inside the thermal management module, the battery, and the motor. The thermal management module can be connected with the battery and / or the motor through direct insertion and butt joint of the fluid interface and the electrical interface, and thus the assembly of the thermal management system is completed. In this way, the thermal management system or the thermal management module is highly integrated, thereby achieving the effects of fully utilizing the internal space of the electric motorcycle and reducing the installation complexity.

[0021] Embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0022] Figure 1 A thermal management system 1000 for an electric motorcycle is shown, according to an embodiment of the present disclosure. The electric motorcycle can be a purely electrically driven motorcycle, or a hybrid electrically and fuel driven motorcycle. The thermal management system 1000 can include a base plate 1100, a motor thermal management loop 1200, a battery thermal management loop 1300, and an electrical wiring.

[0023] Here, the motor thermal management loop 1200 can be formed by fluidly connecting the motor conduit 1210 with the motor 1220, and having a first fluid 1230 disposed therein for cooling and / or heating the motor. Similarly, the battery thermal management loop 1300 can be formed by fluidly connecting the battery conduit 1310 with the battery 1320, and having a second fluid 1330 disposed therein for cooling and / or heating the battery. It should be understood that the conduit can be any connection capable of fluid transport, such as a hose or a pipe connecting the components, preferably a rubber tube, a nylon tube, a plastic tube, a metal tube, or other tubular member capable of performing the above functions. It should be understood that the fluid can be any substance capable of heat exchange, such as a gas, water, ethanol, glycerol, ethylene glycol, a mixture of the foregoing, or other substance capable of performing the above functions. Preferably, the first fluid and the second fluid can be the same or different fluid medium (e.g., coolant), and at least one of them can be a fluid medium having both cooling and heating functions.

[0024] Here, the electrical wiring is used for electrical connection of the thermal management system 1000, such as for electrical connection of the base plate 1100, the battery thermal management loop 1300, the motor thermal management loop 1200, and other components of the thermal management system. In other words, the electrical wiring can be used for electrical connection of the entire or a portion of the thermal management system or thermal management module. In the context of the present disclosure, the electrical wiring can be any electrical component capable of electrical connection or capable of transmitting electrical current between electrical devices, such as a wire, a printed circuit board, or other electrical component capable of performing the above functions.

[0025] Advantageously, the motor lines 1210, the battery lines 1310 and the electrical lines are all integrated on a base plate 1100 of the thermal management system. Here, the base plate can be any carrier capable of integrating the electrical lines and the fluid lines. In the thermal management system 1000, all lines for fluidic or electrical connections are either provided on the base plate or in the housing or in the interior of the motor or the battery, without any fluid lines or electrical lines being provided outside or between these components (base plate or housing, motor and battery). Thus, the thermal management system or the thermal management module according to the present disclosure does not require a separate installation of the lines, which reduces the installation effort and complexity of the e-motorcycle.

[0026] Furthermore, the motor thermal management circuit 1200 can also comprise a motor heat sink 1240, a first fluid tank 1250 and a first fluid pump 1260. Advantageously, these components can also be mounted (e.g. by screw connections) on the base plate 1100 and fluidically connected to each other by the motor lines 1210. Similarly, the battery thermal management circuit 1300 can also comprise a battery heat sink 1340, a second fluid tank 1350 and a second fluid pump 1360. Advantageously, these components can also be mounted (e.g. by screw connections) on the base plate 1100 and fluidically connected to each other by the battery lines 1310.

[0027] In a preferred embodiment, the battery thermal management circuit 1300 can also comprise a semiconductor refrigerator 1390. The semiconductor refrigerator can be mounted (e.g. by screw connections) on the base plate 1100 and electrically connected by the electrical lines. Preferably, the semiconductor refrigerator can be used for heating, e.g. indirectly by the second fluid and / or directly to the battery, in case of a forward current, and for cooling, e.g. indirectly by the second fluid and / or directly to the battery, in case of a reverse current. Preferably, the opening or closing of the semiconductor refrigerator and the direction of the current can be controlled by a controller.

[0028] Within the scope of this disclosure, the heat dissipation device can be any device that uses thermally conductive materials and heat transfer media and transfers heat from a heat source to the environment, for example, through a surface, such as an aluminum alloy heat sink, a copper heat sink, or other devices that achieve the above-mentioned functions. It should be understood that the battery heat dissipation device 1340 and the motor heat dissipation device 1240 can be detachably mounted to the substrate via threaded connections, keyed connections, riveted connections, etc., or can be non-detachably mounted to the substrate via welding connections, etc. Within the scope of this disclosure, the fluid storage tank can be any open or closed container capable of storing fluid. Within the scope of this disclosure, the fluid pump can be any conveying device capable of using electrical energy, mechanical energy, or other energy to transport or pressurize fluid, preferably an electric pump. Preferably, the opening or closing of the first fluid pump and the second fluid pump, as well as the flow rate, can be controlled by a controller to adapt to different thermal management requirements. Furthermore, all fluid connections within the substrate can be sealed using sealing methods such as rubber sealing rings.

[0029] In a preferred embodiment, such as Figure 1 As shown, 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. The circulation loop 1500 can be used to control whether different thermal management loops are connected to allow for fluid exchange. For example, when the battery temperature is low, the heat dissipated by the motor can be used for battery heating (or vice versa) through fluid exchange, thereby reducing the system's energy consumption.

[0030] The circulation loop 1500 may further include a first circulation pump 1520 disposed in a first fluid tank 1250, a second circulation pump 1530 disposed in a second fluid tank 1350, and a circulation pipeline 1510. Here, the circulation pipeline 1510 is used to fluidly connect the first circulation pump 1520 to the second fluid tank 1350, and to fluidly connect the second circulation pump 1530 to the first fluid tank 1250. Preferably, the circulation loop may have at least a closed state and an open state. When the circulation loop is in the closed state, the first fluid tank 1250 and the second fluid tank 1350 are separated, and the first fluid and the second fluid do not flow into each other (i.e., the first fluid and the second fluid circulate in their respective loops, and fluid from one loop does not flow into the other loop), thus the motor thermal management loop and the battery thermal management loop can operate independently of each other. When the circulation loop is open, the first fluid tank 1250 and the second fluid tank 1350 can be connected through the circulation pipeline, so that the first fluid and the second fluid can flow into each other (that is, the first fluid and the second fluid can flow into the other loop from one loop). 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 flow into each other and achieve heat exchange.

[0031] The thermal management system 1000 can further comprise a controller for controlling the opening or closing state of the first circulation pump, the second circulation pump or the flow rate thereof, so as to control whether the first fluid and the second fluid in the motor thermal management circuit and the battery thermal management circuit are circulated and the size of the circulation. Specifically, temperature sensors 1296, 1396 can be used to detect the temperature of the battery and the motor in real time or at irregular time. When the battery temperature is detected to be lower than a preset battery low temperature threshold (for example, in the range of -10°C to 10°C, and more preferably in the range of -5°C to 5°C, and more preferably 0°C) and the motor temperature is higher than the battery temperature (for example, in the case of winter or motorcycle ambient temperature is low), the controller can send a control signal to open the first circulation pump and the second circulation pump, so that the circulation circuit is in an open state, thereby realizing heat exchange between the battery thermal management circuit and the motor thermal management circuit. In this way, the heat of the motor can be used to heat the battery, which on the one hand makes full use of the heat of the motor, and on the other hand avoids the running failure of the battery at low temperature. It is envisaged that the heat of the battery can also be used to heat the motor in a similar manner if necessary. The controller can also be used to control the opening or closing of the semiconductor refrigeration piece 1390 and the current direction. For example, when the battery temperature is lower than the preset battery low temperature threshold, the controller sends a control signal to open the semiconductor refrigeration piece and the current is in the forward direction, so that the semiconductor refrigeration piece 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 more preferably 40°C), the controller can send a control signal to reverse the current of the semiconductor refrigeration piece, so that the semiconductor refrigeration piece 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 close the semiconductor refrigeration piece.

[0032] Figure 2 An exemplary thermal management module according to an embodiment of the present disclosure is shown. 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 parts other than the battery and the motor. Therefore, the solutions described in the present disclosure with respect to the thermal management system (for example, by means of Figure 1 ) can also be adaptively applied to the thermal management module, and vice versa. The foregoing will not be repeated.

[0033] As Figure 2As shown, the thermal management module 2000 can include a housing, a motor circuit 1210, a battery circuit 1310, and electric lines, and the first fluid 1230 and the second fluid 1330 flow through the motor circuit 1210 and the battery circuit 1310, respectively. In the context of the present disclosure, the housing can be understood as any carrier that is alternative or additional to the substrate 1100. Therefore, the aforementioned components integrated on the substrate 1100 can also be alternatively or additionally arranged in the housing, thereby similarly or further improving the integration of the module.

[0034] Here, the first fluid tank 1250 and the second fluid tank 1350 provide sufficient storage space for the first fluid and the second fluid, respectively. Preferably, the first fluid tank 1250 and the second fluid tank 1350 are arranged in the upper region of the thermal management module, and a tank filler 1251, 1351 for injecting the first fluid and the second fluid, respectively, is provided on the upper side of each of them, so that the user only needs to conveniently open the tank filler located at the uppermost side of the thermal management module without having to touch other components. Alternatively, the first fluid tank 1250 and the second fluid tank 1350 can be constituted by two independent tanks. In order to make full use of the interior space of the vehicle body, the two tanks can be designed to have the same or similar size and shape, and arranged side by side in the upper region of the thermal management module. Alternatively, the first fluid tank 1250 and the second fluid tank 1350 can also be constituted in one tank, and the tank is divided into two tank regions by a partition plate arranged in the middle of the tank, thereby forming the first fluid tank 1250 and the second fluid tank 1350.

[0035] Here, the first fluid pump 1260 and the second fluid pump 1360 can be used to provide power for the fluids, so that the first fluid 1230 and the second fluid 1330 flow in the motor thermal management circuit 1200 and the battery thermal management circuit 1300, respectively, thereby achieving the thermal management effect. Preferably, the first fluid pump 1260 and the second fluid pump 1360 can be electronic pumps, which can include an electric plug and a pump fluid interface. In order to facilitate installation, the electric plug and the pump fluid interface are preferably located on the same side of the electronic pump. Correspondingly, an electric socket, a fluid inlet and a fluid outlet corresponding to the position of the electronic pump can be provided on the substrate. The electric plug of the electronic pump and the electric socket on the substrate can be electrically connected by plugging, and the pump fluid interface of the electronic pump and the fluid inlet and the fluid outlet on the substrate can be fluidly connected by plugging. In addition, the electronic pump can also be assembled to the substrate by a detachable structure such as a screw and a screw hole. In order to increase the fluid seal, a sealing member such as a rubber sealing ring can also be considered at the pump fluid interface.

[0036] Here, the motor circuit 1210 can be fluidly connected to other components in the motor thermal management circuit 1200 from the first fluid inlet 1271 by the shortest horizontal and / or vertical path, thereby reducing flow resistance and power requirements for the fluid pump. At the motor heat sink 1240, the motor circuit 1210 can be arranged in an S-shape to allow sufficient heat exchange between the first fluid in the motor circuit and the motor heat sink. The first fluid eventually flows along the motor circuit to the first fluid outlet 1272, exiting the thermal management module and flowing to the fluid conduit disposed inside the motor or battery directly plugged with the thermal management module.

[0037] Here, the battery circuit 1310 can be fluidly connected to other components in the battery thermal management circuit 1300 from the second fluid inlet 1371 by the shortest horizontal and / or vertical path, thereby reducing flow resistance and power requirements for the fluid pump. At the battery heat sink 1340, the battery circuit 1310 can be arranged in an S-shape to allow sufficient heat exchange between the second fluid in the battery circuit and the battery heat sink. The second fluid eventually flows along the battery circuit 1310 to the second fluid outlet 1372, exiting the thermal management module and flowing to the fluid conduit disposed inside the motor or battery directly plugged with the thermal management module.

[0038] In a preferred embodiment, at the semiconductor refrigeration sheet 1390, the battery circuit 1310 can be arranged in an S-shape to allow sufficient heat exchange between the second fluid in the battery circuit and the semiconductor refrigeration sheet. The semiconductor refrigeration sheet can be arranged in the lower half region (e.g. bottom region) of the substrate and can at least partially overlap with the battery circuit 1310. It should be understood that the location of the semiconductor refrigeration sheet on the substrate is not limited and can be adjusted according to the location of the battery or battery circuit as long as it can partially cover the battery circuit and / or the battery, and preferably does not cover any motor circuit.

[0039] Figure 3 An exemplary arrangement of the thermal management module 2000 is shown. In this example, the first fluid tank 1250 and the second fluid tank 1350 are arranged side by side in the top region of the thermal management module, the first fluid pump 1260 and the second fluid pump 1360 are arranged in the two side regions of the thermal management module respectively, and the motor heat sink 1240 and the battery heat sink 1340 are arranged in the middle region of the substrate in sequence from top to bottom. With this layout, the fluid connection and electrical connection between components are as short as possible, thereby reducing flow resistance and complexity of electrical wiring.

[0040] Preferably, a liquid level sensor 1280, 1380 can be provided in the first fluid tank 1250 and the second fluid tank 1350, respectively. The liquid level sensor 1280, 1380 can be electrically connected by an electrical line and used to detect the fluid storage in the first fluid tank 1250 and the second fluid tank 1350 in real time or at irregular intervals. When the liquid level in the fluid tank is detected to be lower than a preset liquid level threshold, a user can be reminded to add fluid, so as to avoid the situation that the thermal management system and / or the thermal management module cannot normally operate due to insufficient fluid.

[0041] In addition, the thermal management module 2000 can further include fans 1130, for example, six to eight fans. The fans 1130 are electrically connected by an electrical line, 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 also helps to avoid the attachment of dirt and other debris that may be splashed when the motorcycle is running 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 can be located on one side of the motor heat sink and the battery heat sink. In addition, the number and position of the fan can be flexibly adjusted according to actual needs. Preferably, the operation of the fan can also be controlled by the controller according to the use demand. For example, when the battery temperature is higher 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) or the motor temperature is higher than a preset motor high temperature threshold (for example, in the range of 55°C to 100°C, preferably in the range of 75°C to 95°C, and particularly preferably 85°C), the controller can issue a control signal to make the fan operate. Here, it should be understood that the control signal of the fan is not necessarily limited to the temperature of the battery or necessarily limited to the temperature of the motor. For example, the fan installed on one side of the battery heat sink can operate when the battery temperature is higher than the preset high temperature threshold, and the fan installed on one side of the motor heat sink can operate when the motor temperature is higher than the preset high temperature threshold.

[0042] Figure 4An exemplary fluidic and electrical interface of the thermal management module 2000 is shown. As described above, the thermal management module 2000 includes a first fluidic interface, a second fluidic interface, and an electrical interface, wherein the first fluidic interface can include a first fluidic inlet and a first fluidic outlet, and the second fluidic interface can include a second fluidic inlet and a second fluidic outlet. In a preferred embodiment, all or a portion of the first fluidic inlet, the first fluidic outlet, the second fluidic inlet, the second fluidic outlet, and the electrical interface 1410 can be provided in one connector interface. In this way, the fluidic and electrical connections of the thermal management module can be accomplished simultaneously through one connector interface, or the fluidic connections of the battery thermal management circuit and the motor thermal management circuit can be accomplished simultaneously.

[0043] Preferably, the first fluidic inlet 1271, the first fluidic outlet 1272, the second fluidic outlet 1372, and the electrical interface 1410 can be collectively provided in one connector interface 1120, while the second fluidic inlet 1371 is provided outside the connector interface 1120.

[0044] In the connector interface 1120, the first fluidic inlet 1271 and the first fluidic outlet 1272 are provided side by side in the upper portion of the connector interface, the second fluidic outlet is provided in the middle portion of the connector interface, and the electrical interface is provided in the lower portion of the connector interface. It should be understood that the layout among the first fluidic inlet 1271, the first fluidic outlet 1272, the second fluidic outlet 1372, and the electrical interface 1410 in the thermal management module is not limited to the above-described manner, and the number and arrangement of the interfaces inside the connector interface 1120 can be adjusted according to the needs of the fluidic and electrical lines or according to the corresponding interfaces on the battery or the motor.
