Description

Thermal management device, charging system and charging pile for electric vehicles

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on October 23, 2023, with application number 202311379785.3 and application name “Thermal management device, charging system and charging pile for electric vehicles”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of electric vehicles, and more specifically, to a thermal management device for an electric vehicle, a charging system including the thermal management device for an electric vehicle, and a charging pile including the thermal management device for an electric vehicle or the above-mentioned charging system. Background Art

[0003] With the rapid development of pure electric vehicles and plug-in electric vehicles in the domestic and international automotive fields, and the increasingly comprehensive functional configurations of various vehicles, consumers are now placing higher and higher demands on the capacity of energy storage components, namely power battery packs. At the same time, consumers are also placing higher demands on charging speed and efficiency.

[0004] Pure electric passenger cars for household use typically require a one-hour recharge time to meet convenience requirements. Advances in distribution grids and charging stations have made it possible to shorten charging times by increasing charging power. However, this increase in charging power and current also places higher demands on battery thermal management. Currently, electric vehicles rely on the cooling capacity of their air conditioning systems to cool their power batteries.

[0005] As mentioned above, the existing battery cooling and heating functions are achieved by relying on the air conditioning system of the electric vehicle itself to achieve refrigeration, thereby cooling the antifreeze, and then cooling the battery through the flow of the antifreeze.

[0006] The power battery cooling functions of existing electric and hybrid vehicles on the market primarily rely on passive cooling and active cooling methods. For passive cooling, when the ambient temperature is relatively low, the cooling circuits are connected in series through a four-way valve. Driven by a water pump, the coolant transfers the heat generated by the power battery to the radiator. Air, driven by a fan, flows through the radiator, removing the heat from the coolant flowing through the radiator, thereby cooling the power battery. For active cooling, when the ambient temperature is relatively high, direct heat dissipation from the power battery through the radiator is not possible. In this case, the cooling circuits are connected in parallel through the switching of the four-way valves. The coolant flows through a heat exchanger, first transferring the heat from the power battery to the refrigerant in another circuit, and then through a condenser to the external environment. Under these operating conditions, the battery's cooling capacity is limited by the ambient temperature; higher ambient temperatures result in lower cooling capacity.

[0007] When a vehicle is charged at high power, the power battery will generate a large amount of heat. If the heat cannot be removed in time, the charging power will be limited to ensure the safety of the power battery.

[0008] When charging in a high-temperature environment, the coolant in the cooling circuit, driven by a water pump, removes the heat generated by the power battery and transfers the heat to the refrigerant in another circuit through a heat exchanger. The refrigerant flows through the condenser under the drive of the compressor, and the ambient air flows through the condenser under the action of a fan, removing the heat from the condenser. However, when the ambient temperature is too high, the difference between the temperature of the air flowing through the outside of the condenser and the temperature of the refrigerant flowing through the inside of the condenser decreases, resulting in a decrease in the cooling effect of the condenser, which in turn affects the cooling capacity of the power battery, causing the battery charging power to decrease, and thus increasing the time required for charging. At this time, models capable of super-fast charging may not be able to enter the super-fast charging mode due to the high battery temperature.

[0009] Summary of the Invention

[0010] To address the aforementioned issue, namely that the existing temperature control achieved by vehicle air conditioning does not meet the cooling power requirements and is dependent on the ambient temperature, thereby affecting the overall temperature control effect on the power battery, which in turn may adversely affect the rapid charging of the power battery and potentially prolong the charging time, both of which are detrimental to the development of electric vehicles, the inventors of the present disclosure have innovatively devised a method of utilizing an external refrigeration system to reduce the ambient temperature of the environment in which the power battery is located, thereby accelerating the cooling rate of the power battery and ensuring smooth rapid charging of the power battery.

[0043] As mentioned above, in one example, the cooling power of the temperature control achieved by the vehicle air conditioner cannot meet the requirements and is dependent on the ambient temperature, thereby affecting the overall temperature control effect of the power battery, which may have an adverse effect on the rapid charging of the power battery and may prolong the charging time, which is not conducive to the development of electric vehicles.

[0044] In order to solve the above technical problems, the inventors of the present disclosure innovatively thought of using an external refrigeration system to lower the ambient temperature of the environment in which the power battery is located, thereby accelerating the cooling speed of the power battery and ensuring that the power battery can be quickly charged smoothly, thereby making the cooling speed of the power battery pack reach an ideal state, increasing the charging power and shortening the charging time, thereby improving customer satisfaction and product competitiveness. The present disclosure proposes a thermal management device for an electric vehicle, the thermal management device includes a connecting device, wherein the connecting device includes: an air inlet arranged on a first end thereof; an air outlet arranged on a second end thereof; a channel for gas circulation arranged in the connecting device, one end of the channel being the air inlet and the other end of the channel being the air outlet, wherein the air inlet is used to receive gas, the temperature of the gas flowing in through the air inlet is lower than the ambient temperature of the environment in which the thermal management device is located, and the gas flows out of the air outlet after passing through the channel, and wherein the second end of the connecting device is used to connect or contact the grille of the electric vehicle, the edge of the second end of the connecting device can cover the grille of the electric vehicle, and the temperature of the gas flowing out through the air outlet is lower than the ambient temperature, so as to cool the components in the grille. In this way, the gas outside the vehicle that is lower in temperature than the ambient temperature can be input into the space behind the vehicle's grille under the action of the connecting device. The power battery is stored in this space, thereby accelerating the cooling process of the power battery to meet the cooling requirements during charging of the power battery, so that the cooling speed of the power battery pack reaches an ideal state, the charging power is increased, the charging time is shortened, and customer satisfaction and product competitiveness are improved.

[0045] The following describes a thermal management device, a charging pile, and a corresponding charging system according to the present disclosure in conjunction with the accompanying drawings. FIG1 shows an exemplary block diagram of a thermal management device according to one embodiment of the present disclosure, FIG2 shows an exemplary block diagram of a thermal management device according to another embodiment of the present disclosure, FIG3 shows an exemplary block diagram of a thermal management device according to yet another embodiment of the present disclosure, and FIG4 shows an exemplary block diagram of a charging system according to one embodiment of the present disclosure.

[0046] As can be seen from FIG1 , the thermal management device 100 for an electric vehicle according to the present disclosure at least includes a connecting device 110, wherein the connecting device 110 includes an air inlet 111 provided on a first end thereof (e.g., the left end shown in FIG1 ), an air outlet 112 provided on a second end thereof (e.g., the right end shown in FIG1 ), and a channel 113 for gas circulation provided in the connecting device 110, wherein one end of the channel 113 is the air inlet 111 and the other end of the channel 113 is the air outlet 112, wherein the air inlet 111 is provided on a first end thereof (e.g., the left end shown in FIG1 ), an air outlet 112 provided on a second end thereof (e.g., the right end shown in FIG1 ), and a channel 113 for gas circulation provided in the connecting device 110, wherein the air inlet 111 is provided on a first end thereof (e.g., the left end shown in FIG1 ), an air outlet 112 provided on a second end thereof (e.g., the right end shown in FIG1 ). 11 is used to receive gas. The temperature of the gas flowing in through the air inlet 111 is lower than the ambient temperature of the environment in which the thermal management device 100 is located. The gas flows out of the air outlet 112 after passing through the channel 113. In addition, the second end of the connecting device 110 is used to connect to or contact the grille of the electric vehicle (not shown in the figure). The edge of the second end of the connecting device 110 can cover the grille of the electric vehicle. The temperature of the gas flowing out of the air outlet 112 is lower than the ambient temperature, thereby cooling the components within the grille. In this way, the gas outside the vehicle with a lower temperature than the ambient temperature can be input into the space behind the vehicle grille under the action of the connecting device 110. The power battery is stored in this space, thereby accelerating the cooling process of the power battery to meet the cooling requirements during charging of the power battery, so that the cooling speed of the power battery pack reaches an ideal state, improving charging power and shortening charging time, thereby improving customer satisfaction and product competitiveness.

[0047] Here, the temperature of the gas entering through the air inlet is lower than the ambient temperature of the environment in which the thermal management device is located. For example, gas can be extracted from the basement of a building or from other locations where the temperature is lower than the current ambient temperature, and the temperature of the gas at these locations is lower than the current ambient temperature. That is, the thermal management device according to the present disclosure includes at least one connecting device 110, which is used to adapt to the grille of the electric vehicle and is provided with an outlet 112 on one side of the connecting device 110 (for example, the right side as shown in Figure 1) that is fluidly connected to the air inlet 111, wherein the outer contour of the outlet 112 of the connecting device 110 (for example, an elastic body with adjustable shape and size around the periphery) can cover the grille and output gas below the ambient temperature through the outlet 112. Here, the outlet 112 can be set as a small opening on the outer shell of the connecting device 110, or it can be designed as an outlet of a size corresponding to the opening formed by the elastomer covering the grille. In one embodiment of the present disclosure, to accommodate the varying sizes of the front grilles of different electric vehicles being charged, the side of the connection device 110 closest to the electric vehicle (e.g., the right side in FIG1 ) is configured to be scalable, allowing its size to be adapted to the size of the grille. In this manner, the thermal management device 100 for electric vehicles according to the present disclosure can adapt to varying vehicle front fascia sizes, expanding its application scenarios.

[0048] Furthermore, since different electric vehicles to be charged have different cooling requirements, corresponding control modules or control devices can also be designed, such as flow rate control devices (not shown in the figure), which are fluidically connected to the air inlet and configured to adjust the gas flow rate at the air outlet. In this way, the thermal management device for electric vehicles according to the present disclosure can provide gas with corresponding flow rates according to the cooling requirements of different vehicles at different ambient temperatures and different charging currents, so that the thermal management device for electric vehicles according to the present disclosure can more specifically meet the cooling requirements of electric vehicles to be charged.

[0049] Furthermore, in order to further control the temperature entering the thermal management device according to the present disclosure, the thermal management device according to the present disclosure can also include a refrigeration device. Figure 2 shows an exemplary block diagram of a thermal management device according to another embodiment of the present disclosure. As can be seen from Figure 2, the thermal management device according to the present disclosure mainly includes two parts. First, the thermal management device 200 according to the present disclosure includes a connecting device 210, the connecting device 210 includes an air inlet 211 provided on its first end (for example, the left end shown in Figure 2), an air outlet 212 provided on its second end (for example, the right end shown in Figure 2), and a channel 213 for gas circulation provided in the connecting device 210, one end of the channel 213 is the air inlet 211 and the other end of the channel 213 is the air outlet 212, wherein The air inlet 211 is used to receive gas. The temperature of the gas flowing in through the air inlet 211 is lower than the ambient temperature of the environment in which the thermal management device 200 is located. The gas flows through the channel 213 and then flows out of the air outlet 212. The second end of the connecting device 210 is used to connect to or contact the grille of the electric vehicle (not shown in the figure). The edge of the second end of the connecting device 210 can cover the grille of the electric vehicle. The temperature of the gas flowing out of the air outlet 212 is lower than the ambient temperature, thereby cooling the components within the grille. In this way, the connecting device 210 can input gas outside the vehicle with a lower temperature than the ambient temperature into the space behind the vehicle grille, where the power battery is stored. This space can accelerate the cooling process of the power battery to meet the cooling requirements during charging, so that the cooling speed of the power battery pack reaches an ideal state, improving charging power and shortening charging time, thereby enhancing customer satisfaction and product competitiveness. Furthermore, the thermal management device 200 further includes a refrigeration device 220, which is connected to the connection device 210, for example, via a pipe 222, and is configured to output gas at a temperature lower than the ambient temperature to the air inlet 211. In this manner, the thermal management device 200 for an electric vehicle according to the present disclosure can include an independent refrigeration device 220, thereby being able to provide gas at a temperature lower than the ambient temperature independently of the operation of an external refrigerator, thereby further expanding the application scenarios of the thermal management device 200 for an electric vehicle according to the present disclosure.

[0050] In order to enable the connecting device 210 to better cover the air intake grille of the electric vehicle to be charged, the right side of the shell of the connecting device 210 can, for example, include an outer frame (e.g., around the air outlet 212) and an inner frame (the shell portion forming the air outlet 212), wherein the outer frame is located outside the inner frame, the channel 213 is arranged inside the inner frame, and the size of the inner frame is adjustable. In order to further improve the sealing between the connecting device 210 and the electric vehicle to be charged, and thereby improve the utilization rate of the gas used for cooling, the connecting device 210 also includes a sealing structure (not shown in the figure), which is arranged at the air outlet 212 and is used to form a sealed connection between the air outlet 212 and the grille. Specifically, the sealing structure is constructed as an elastic member, for example. At this time, the connecting device 210 also includes an elastic member (not shown in the figure), which is arranged at the second end (the right end in Figure 2) of the connecting device 210, and the elastic member is used to seal with the shell of the vehicle.

[0051] In order to obtain the target flow rate value, in one embodiment according to the present disclosure, the thermal management device 200 also includes an input device (not shown in the figure, such as a touch screen), which is used to receive the target flow rate value, and the flow rate control device is used to adjust the gas flow rate at the outlet 212 according to the target flow rate value.

[0052] In addition, the thermal management device 200 can further include, for example, a control module (e.g., a microcontroller unit, MCU), which is connected to the refrigeration device 220 and configured to adjust the temperature of the gas output by the refrigeration device 220 to the air inlet 211. To obtain a target temperature value, the thermal management device 200 also includes an input device (not shown in the figure, such as a touch screen), which is used to receive the target temperature value. The control module is used to adjust the temperature of the gas output by the refrigeration device 220 to the air inlet 211 via the pipeline 222 according to the target temperature value.

[0053] The structure of the refrigeration device 220 according to the contents of the present disclosure will be further described below. Here, the refrigeration device 220 includes a compressor, an evaporator, a condenser, and a refrigerant pipeline for connecting the compressor, evaporator and condenser. In this way, the thermal management device according to the contents of the present disclosure also has a refrigerant pipeline, so that the temperature of the gas entering the connecting device 210 can be further optimized and adjusted. Here, one connecting device 210 can be used as one refrigeration device 220, or two or three connecting devices 210 can share one refrigeration device 220. In one embodiment of the contents of the present disclosure, one refrigeration device 220 is connected to one connecting device 210, or one refrigeration device 220 is connected to at least two connecting devices 210.

[0054] In order to adjust the position of the connection device according to the present disclosure, FIG3 shows an exemplary block diagram of a thermal management device 300 according to another embodiment of the present disclosure.

The temperature of the gas flowing in through the air inlet 311 is lower than the ambient temperature of the environment in which the thermal management device 300 is located. The gas flows through the channel 313 and flows out of the air outlet 312. The second end of the connecting device 310 is used to connect to or contact the grille of the electric vehicle (not shown in the figure). The edge of the second end of the connecting device 310 can cover the grille of the electric vehicle. The temperature of the gas flowing out of the air outlet 312 is lower than the ambient temperature, thereby cooling the components within the grille. In this way, the connecting device 310 can be used to input gas outside the vehicle with a lower temperature than the ambient temperature into the space behind the vehicle grille. The power battery is stored in this space, thereby accelerating the cooling process of the power battery to meet the cooling requirements during charging of the power battery, so that the cooling speed of the power battery pack reaches an ideal state, improving charging power and shortening charging time, thereby improving customer satisfaction and product competitiveness. Furthermore, the thermal management device 300 further includes a refrigeration device 320, which is connected to the connection device 310, for example, via a pipe 322, and is configured to output gas at a temperature lower than the ambient temperature to the air inlet 311. In this manner, the thermal management device 300 for an electric vehicle according to the present disclosure can include an independent refrigeration device 320, thereby being able to provide gas at a temperature lower than the ambient temperature independently of the operation of an external refrigerator, thereby further expanding the application scenarios of the thermal management device 300 for an electric vehicle according to the present disclosure.

[0055] In order to enable the connecting device 310 to better cover the air intake grille of the electric vehicle to be charged, the right side of the shell of the connecting device 310 can, for example, include an outer frame (e.g., around the air outlet 312) and an inner frame (the shell portion forming the air outlet 312), wherein the outer frame is located outside the inner frame, and the channel 313 is arranged inside the inner frame, and the size of the inner frame is adjustable. In order to further improve the sealing between the connecting device 310 and the electric vehicle to be charged, and thereby improve the utilization rate of the gas used for cooling, the connecting device 310 also includes a sealing structure (not shown in the figure), which is arranged at the air outlet 312 and is used to form a sealed connection between the air outlet 312 and the grille. Specifically, the sealing structure is constructed as an elastic member, for example. At this time, the connecting device 310 also includes an elastic member (not shown in the figure), which is arranged at the second end (the right end in Figure 3) of the connecting device 310, and the elastic member is used to seal with the shell of the vehicle.

[0056] In order to obtain the target flow rate value, in one embodiment according to the present disclosure, the thermal management device 300 also includes an input device (not shown in the figure, such as a touch screen), which is used to receive the target flow rate value, and the flow rate control device is used to adjust the gas flow rate at the outlet 312 according to the target flow rate value.

[0058] The structure of the refrigeration device 320 according to the contents of the present disclosure will be further described below. Here, the refrigeration device 320 includes a compressor, an evaporator, a condenser, and a refrigerant pipeline for connecting the compressor, evaporator and condenser. In this way, the thermal management device according to the contents of the present disclosure also has a refrigerant pipeline, so that the temperature of the gas entering the connecting device 310 can be further optimized and adjusted. Here, one connecting device 310 can use one refrigeration device 320, or two or three connecting devices 310 can share one refrigeration device 320. In summary, in one embodiment according to the contents of the present disclosure, one refrigeration device 320 is connected to one connecting device 310, or one refrigeration device 320 is connected to at least two connecting devices 310. In other words, generally speaking, one charging pile needs to be equipped with one connecting device, but multiple charging piles can share one cold source, that is, a common refrigeration device.

[0059] In addition, the thermal management device 300 also includes a moving device 330 (for example, a roller as shown in the figure), which is arranged on the connecting device 310 (for example, at the bottom of the connecting device 310 in the figure) and is configured to adjust the position of the connecting device 310 relative to the grille of the electric vehicle (not shown in the figure). In this way, the thermal management device 300 for electric vehicles according to the present disclosure can be moved to the position of the electric vehicle to be charged after determining the position of the electric vehicle to be charged, so that the connecting device 310 can be conveniently mechanically connected to it. For example, the movable cold air module is integrated with a travel mechanism 330, which is driven by its own motor and can automatically move according to the position of the charging vehicle detected by the vehicle cover assembly camera, ensuring that the vehicle grille cover assembly and the charging vehicle grille are aligned, and providing retention force between the vehicle grille cover assembly and the charging vehicle grille, ensuring the seal between the vehicle grille cover assembly and the charging vehicle grille during operation. The movable cold air module and the refrigeration unit are connected by an elastic pipe 322 to ensure that the movable cold air module can move within the designed range to meet the mobility requirements of different vehicle models and different parking locations; the outside of the elastic pipe 322 is protected by a bellows to ensure that the internal elastic pipe 322 is not worn or damaged.

[0060] After being able to move, in one embodiment according to the present disclosure, it is possible that the thermal management device 300 further includes a locking device (for example, a bearing pin capable of locking the above-mentioned roller, which can stop the roller from rotating), and the locking device locks the connecting device when the connecting device 310 reaches a predetermined position. In this way, the thermal management device 300 for an electric vehicle according to the present disclosure can be moved to the position of the electric vehicle to be charged after determining the position of the electric vehicle to be charged, and then the connecting device can be conveniently mechanically connected thereto. Then, in order to further improve the connection effect, the connecting device can be locked with the help of the locking device.

[0061] In addition, the thermal management device 300 also includes a communication module (such as a communication chip) and a control module (such as a microcontroller chip MCU), wherein the communication module is used to obtain the position information of the electric vehicle, and the control module is used to control the moving device to drive the connecting device to move according to the position information, so that the connecting device is connected or in contact with the grille. In this way, the thermal management device for electric vehicles according to the contents of the present disclosure can obtain the position information of the electric vehicle to be charged, so that the connecting device can be conveniently moved to the position of the electric vehicle and mechanically connected thereto. For example, the communication module can be used to communicate and connect with smart devices such as mobile phones and PADs, and then the thermal management device according to the contents of the present disclosure can be set through these smart devices. In one embodiment of the present disclosure, the communication module is also configured to obtain the size information of the grille, and the control module is also used to adjust the size of the second end of the connecting device according to the size information of the grille, so that the connecting device is adapted to the grille.

In this way, the thermal management device 300 for an electric vehicle according to the present disclosure can acquire the position information of the electric vehicle to be charged, thereby enabling the connection device 310 to be conveniently moved to the location of the electric vehicle and mechanically connected thereto. For example, a thermal management device 300 with a camera can be set up around the charging pile. When it is detected that an electric vehicle to be charged is approaching, the specific position of the electric vehicle to be charged can be analyzed based on the picture or image taken by the camera. Then, the connecting device 310 can be moved to a relatively close position and then mechanically connected to it to ensure that the gas output from the outlet 312 can enter the grille of the electric vehicle to be charged.

[0063] In one embodiment of the present disclosure, the control module is further configured to obtain size information of the grille of the electric vehicle based on the image information of the electric vehicle, and to adjust the size of the second end of the connecting device based on the size information of the grille so that the connecting device 310 fits the grille. In this manner, the thermal management device 300 for an electric vehicle according to the present disclosure can dynamically determine the size of the front air intake grille of the electric vehicle to be charged based on the acquired image after determining the location of the electric vehicle to be charged, thereby enabling the connecting device 310 to conveniently adjust the size and mechanically connect thereto.

[0064] In order to facilitate the input of target parameters, the thermal management device 300 includes an input device (not shown in the figure, such as a touch screen), through which the desired flow rate and temperature values ​​can be obtained. Here, the input device is, for example, a touch screen, a button, or input via a keyboard or an intelligent device connected to the thermal management device. In this way, the required input, i.e., the desired flow rate and temperature values, can be input into the thermal management device according to the content of the present disclosure in a targeted manner. Specifically, the user can select automatic control (the movable coolant module provides a wind speed of 2m / s and an outlet air temperature of 25°C by default) or manually set the required cooling capacity on the operation panel according to needs (the cooling capacity can be divided into three levels of low / middle / high or the user can manually adjust the required outlet air speed and outlet air temperature). The control component controls the operation of the refrigeration unit and the movable cold air module according to the user's set value, and provides the cooling capacity, outlet air temperature and outlet air speed set or required by the user. The control module is integrated with a remote control function, and the user can establish a connection with the auxiliary thermal management device by downloading an APP, which can realize the functions of mobile phone reservation or direct control by mobile phone.

[0065] The above example is that the thermal management device according to the contents of the present disclosure includes an independent refrigeration device. Of course, those skilled in the art should understand that the refrigeration device can also reuse an existing refrigeration device, such as the cold air generated by the central air-conditioning of a building. At this time, Figure 4 shows an exemplary block diagram of a thermal management device 400 according to another embodiment of the present disclosure. As can be seen from Figure 4, the thermal management device according to the contents of the present disclosure mainly includes two parts. First, the thermal management device 400 according to the contents of the present disclosure includes a connecting device 410, the connecting device 410 includes an air inlet 411 provided on its first end (for example, the left end shown in Figure 4), an air outlet 412 provided on its second end (for example, the right end shown in Figure 4), and a channel 413 for gas circulation provided in the connecting device 410, one end of the channel 413 is the air inlet 411 and the other end of the channel 413 is the air outlet 412, wherein, The air inlet 411 is used to receive gas. The temperature of the gas flowing in through the air inlet 411 is lower than the ambient temperature of the environment in which the thermal management device 400 is located. The gas flows through the channel 413 and flows out of the air outlet 412. In addition, the second end of the connecting device 410 is used to connect to or contact the grille of the electric vehicle (not shown in the figure). The edge of the second end of the connecting device 410 can cover the grille of the electric vehicle. The temperature of the gas flowing out of the air outlet 412 is lower than the ambient temperature, thereby cooling the components within the grille. In this way, the connecting device 410 can be used to input gas outside the vehicle with a lower temperature than the ambient temperature into the space behind the vehicle grille. The power battery is stored in this space, thereby accelerating the cooling process of the power battery to meet the cooling requirements during charging of the power battery, so that the cooling speed of the power battery pack reaches an ideal state, improving charging power and shortening charging time, thereby improving customer satisfaction and product competitiveness. In addition, secondly, the thermal management device 400 further includes a refrigeration device 420 , which is connected to the connecting device 410 , for example, via a pipe 422 , and is configured to output gas with a temperature lower than the ambient temperature to the air inlet 411 .

[0066] In order to enable the connecting device 410 to better cover the air intake grille of the electric vehicle to be charged, the right side of the shell of the connecting device 410 can, for example, include an outer frame (e.g., around the air outlet 412) and an inner frame (the shell portion forming the air outlet 412), wherein the outer frame is located on the outside of the inner frame, the channel 413 is arranged inside the inner frame, and the size of the inner frame is adjustable. In order to further improve the sealing between the connecting device 410 and the electric vehicle to be charged, and thereby improve the utilization rate of the gas used for cooling, the connecting device 410 also includes a sealing structure (not shown in the figure), which is arranged at the air outlet 412 and is used to form a sealed connection between the air outlet 412 and the grille. Specifically, the sealing structure is constructed as an elastic member, for example. At this time, the connecting device 410 also includes an elastic member (not shown in the figure), which is arranged at the second end (the right end in Figure 3) of the connecting device 410, and the elastic member is used to seal with the shell of the vehicle.

[0068] In addition, the thermal management device 400 can also include, for example, a control module (e.g., a microcontroller MCU), which is connected to the refrigeration device 420 and configured to adjust the temperature of the gas output by the refrigeration device 420 to the air inlet 411. To obtain a target temperature value, the thermal management device 400 also includes an input device (not shown in the figure, such as a touch screen), which is used to receive the target temperature value. The control module is used to adjust the temperature of the gas output by the refrigeration device 420 to the air inlet 411 via the pipeline 422 according to the target temperature value.

[0069] In addition, the thermal management device 400 also includes a moving device 430 (for example, a roller as shown in the figure), which is arranged on the connecting device 410 (for example, at the bottom of the connecting device 410 in the figure) and is configured to adjust the position of the connecting device 410 relative to the grille of the electric vehicle (not shown in the figure). In this way, the thermal management device 400 for electric vehicles according to the present disclosure can be moved to the position of the electric vehicle to be charged after determining the position of the electric vehicle to be charged, so that the connecting device 410 can be conveniently mechanically connected to it. For example, the movable cold air module is integrated with a running mechanism 430, which is driven by its own motor and can automatically move according to the position of the charging vehicle detected by the vehicle cover assembly camera, ensuring that the vehicle grille cover assembly and the charging vehicle grille are aligned, and providing retention between the vehicle grille cover assembly and the charging vehicle grille to ensure the seal between the vehicle grille cover assembly and the charging vehicle grille during operation. The movable cold air module and the refrigeration unit are connected by an elastic pipe 422 to ensure that the movable cold air module can move within the designed range to meet the mobility requirements of different vehicle models and different parking locations; the outside of the elastic pipe 422 is protected by a bellows to ensure that the internal elastic pipe 422 is not worn or damaged.

[0070] After being able to move, in one embodiment according to the present disclosure, it is possible that the thermal management device 400 further includes a locking device (for example, a bearing pin capable of locking the above-mentioned roller, which can stop the roller from rotating), and the locking device locks the connecting device when the connecting device 410 reaches a predetermined position.

[0071] In addition, the thermal management device 400 also includes a communication module (such as a communication chip) and a control module (such as a microcontroller chip MCU), wherein the communication module is used to obtain the position information of the electric vehicle, and the control module is used to control the moving device to drive the connecting device to move according to the position information, so that the connecting device is connected or in contact with the grille. In this way, the thermal management device for electric vehicles according to the contents of the present disclosure can obtain the position information of the electric vehicle to be charged, so that the connecting device can be conveniently moved to the position of the electric vehicle and mechanically connected thereto. For example, the communication module can be used to communicate and connect with smart devices such as mobile phones and PADs, and then the thermal management device according to the contents of the present disclosure can be set through these smart devices. In one embodiment of the present disclosure, the communication module is also configured to obtain the size information of the grille, and the control module is also used to adjust the size of the second end of the connecting device according to the size information of the grille, so that the connecting device is adapted to the grille.

[0072] In one embodiment of the present disclosure, the thermal management device 400 further includes an image acquisition device (not shown), such as a camera and a control module, wherein the image acquisition device is configured to acquire image information of the electric vehicle, and the control module acquires position information of the electric vehicle based on the image information of the electric vehicle. The control module is further configured to control the movement device 430 to move the connection device 410 based on the position information, so that the connection device 410 is connected or in contact with the grille. In this way, the thermal management device 400 for an electric vehicle according to the present disclosure can acquire the position information of the electric vehicle to be charged, thereby enabling the connection device 410 to be conveniently moved to the location of the electric vehicle and mechanically connected thereto. For example, a thermal management device 400 with a camera can be set up around the charging pile.

Then, the connecting device 410 can be moved to a relatively close position and then mechanically connected to it to ensure that the gas output from the outlet 412 can enter the grille of the electric vehicle to be charged.

[0073] In one embodiment of the present disclosure, the control module is further configured to obtain size information of the grille of the electric vehicle based on the image information of the electric vehicle, and to adjust the size of the second end of the connecting device based on the size information of the grille so that the connecting device 410 fits the grille. In this manner, the thermal management device 400 for an electric vehicle according to the present disclosure can dynamically determine the size of the front air intake grille of the electric vehicle to be charged based on the acquired image after determining the location of the electric vehicle to be charged, thereby enabling the connecting device 410 to conveniently adapt to the size and mechanically connect thereto.

[0074] In order to facilitate the input of target parameters, the thermal management device 400 includes an input device (not shown in the figure, such as a touch screen), through which the desired flow rate and temperature values ​​can be obtained. Here, the input device is, for example, a touch screen, a button, or input via a keyboard or an intelligent device connected to the thermal management device. In this way, the required input, i.e., the desired flow rate and temperature values, can be input into the thermal management device according to the content of the present disclosure in a targeted manner. Specifically, the user can select automatic control (the movable coolant module provides a wind speed of 2m / s and an outlet air temperature of 25°C by default) or manually set the required cooling capacity on the operation panel according to needs (the cooling capacity can be divided into three levels of low / middle / high or the user can manually adjust the required outlet air speed and outlet air temperature).

The control module is integrated with a remote control function, and the user can establish a connection with the auxiliary thermal management device by downloading an APP, which can realize the functions of mobile phone reservation or direct control by mobile phone.

[0075] The difference from Figure 3 is that the thermal management device 400 shown in Figure 4 does not have its own independent refrigeration device, but instead its air inlet 411 is connected to a cold air duct 422 of a building central air conditioner 420 with cold air, so that gas below the ambient temperature can be obtained. This not only saves the manufacturing cost of the thermal management device 400 according to the contents of this disclosure, but also improves the efficiency of refrigeration and solves the cost of refrigeration. At this time, the thermal management device 400 can be arranged close to the charging pile 440 and can be shared by multiple charging piles 440 nearby. After the electric vehicle is connected to the charging pile 440 and the thermal management device 400, the thermal management device 400 will automatically identify the charging pile for charging according to the position of the movable cold air module, and the energy consumption costs generated will be included in the charging pile for charging the vehicle.

[0076] The structure of the refrigeration device 420 according to the contents of the present disclosure will be further described below. Here, the refrigeration device 420 includes a compressor, an evaporator, a condenser, and a refrigerant pipeline for connecting the compressor, evaporator and condenser. In this way, the thermal management device according to the contents of the present disclosure also has a refrigerant pipeline, so that the temperature of the gas entering the connecting device 410 can be further optimized and adjusted. Here, one connecting device 410 can use one refrigeration device 420, or two or three connecting devices 410 can share one refrigeration device 420. In summary, in one embodiment according to the contents of the present disclosure, one refrigeration device 420 is connected to one connecting device 410, or one refrigeration device 420 is connected to at least two connecting devices 410. In other words, generally speaking, one charging pile needs to be equipped with one connecting device, but multiple charging piles can share one cold source, that is, a common refrigeration device. As shown in FIG4 , the refrigeration device 420 does not correspond one-to-one with the connection device 410 or is not exclusively used by the connection device 410 , but rather shares the refrigeration device of other connection devices 410 or charging piles 440 , or even shares the refrigeration facilities of a building.

[0077] In addition, the second aspect of the present disclosure provides a charging pile, which includes the thermal management device according to the first aspect of the present disclosure. In other words, the thermal management device can be integrated with the charging pile, so that the charging pile also has an additional thermal management function.

[0078] In addition, the above-mentioned thermal management device can also be constructed relatively independently from the charging pile, but can cooperate with each other during specific operation, that is, the present disclosure also proposes a charging system, which includes the thermal management device proposed according to the first aspect of the present disclosure or the charging pile proposed according to the second aspect of the present disclosure.

[0079] In summary, in the thermal management device, charging system or charging pile for electric vehicles according to the contents of the present disclosure, gas outside the vehicle with a lower temperature than the ambient temperature can be input into the space behind the grille of the vehicle under the action of the connecting device. Power batteries are stored in this space, thereby accelerating the cooling process of the power batteries to meet the cooling requirements during charging of the power batteries, so that the cooling speed of the power battery pack reaches an ideal state, the charging power is increased, the charging time is shortened, and customer satisfaction and product competitiveness are improved.
