In one or more embodiments of the present application, a method for performing thermal management is provided, where a thermal management system of a vehicle includes a control module, a waste heat recovery pipeline 1 connected to a high-pressure component heat exchanger, a first heat exchange pipeline 2 connected to a heat pump air conditioner 20, and a second heat exchange pipeline 3 connected to a battery pack 15. The control module can regulate and control the connection state of the waste heat recovery pipeline 1 and the first heat exchange pipeline 2 and/or the second heat exchange pipeline 3.

As shown in fig. 1, the thermal management execution method includes:

s100, confirming that the vehicle is in an energy-saving mode, and acquiring the predicted driving mileage of the vehicle;

s200, responding to the fact that the predicted driving mileage is larger than a first preset value, obtaining ambient temperature information and battery pack temperature information, and determining a thermal management execution mode according to the ambient temperature information and/or the battery pack temperature information;

and S300, sending an execution signal corresponding to the thermal management execution mode to the control module so as to communicate the waste heat recovery pipeline 1 with the first heat exchange pipeline 2 and/or the second heat exchange pipeline 3.

As can be seen from the above, according to the thermal management execution method provided by the application, when the vehicle is in the energy saving mode, the estimated driving mileage is greater than the first preset value, it is determined that the vehicle is in the long mileage mode, the thermal management execution mode is determined according to the ambient environment temperature information and/or the battery pack temperature information, when the waste heat recovery pipeline 1 is communicated with the first heat exchange pipeline 2, the waste heat generated by the high-pressure component can be conveyed to the heat pump air conditioner 20 for utilization, when the waste heat recovery pipeline 1 is communicated with the second heat exchange pipeline 3, the waste heat generated by the high-pressure component can be conveyed to the battery pack 15 for utilization, by the arrangement, the heat of the waste heat recovery pipeline 1 can be effectively utilized, so that the vehicle can save the energy of the vehicle per se and output the heat pump air conditioner 20 or the battery pack 15 in the energy saving mode, and the environmental temperature comfort of the vehicle member cabin can be improved on the premise of ensuring the vehicle driving mileage as far as possible.

It should be noted that, in the embodiment of the present application, the waste heat recovery pipeline 1 is connected to the high-pressure part heat exchanger 7, the high-pressure part heat exchanger is a heat exchanger connected to the high-pressure part, here, the high-pressure part is a vehicle body related part such as a motor and an electronic control device, the vehicle body related part can continuously generate heat in a working state, the generated heat is conveyed to the waste heat recovery pipeline 1 through the high-pressure part heat exchanger, and through the aforementioned thermal management execution strategy, the heat can be utilized by the heat pump air conditioner 20 or the battery pack 15, so as to improve the waste heat recovery effect of the vehicle. In addition, the heat pump air conditioner 20 may employ a heat exchange device that is well-known in the art and is capable of heating or cooling the passenger compartment by exchanging heat with the external environment or heating the passenger compartment by exchanging heat with the waste heat recovery pipe 1.

In some embodiments, the control module is configured to adjust a connection state of the waste heat recovery pipeline 1, the first heat exchange pipeline 2, and the second heat exchange pipeline 3 through a reversing valve 9, and the control module controls a valve port of the reversing valve 9 to switch to a different pipeline, so as to adjust the connection state of the waste heat recovery pipeline 1, the first heat exchange pipeline 2, and the second heat exchange pipeline 3.

The steps are all carried out when the vehicle is in a starting state, the whole vehicle running mode comprises an energy-saving mode and a non-energy-saving mode, the mode for acquiring the whole vehicle running mode can be that a user manually selects the energy-saving mode after starting the vehicle, or can be automatically adjusted to the energy-saving mode according to the electric quantity of the vehicle, and exemplarily, when the electric quantity of the vehicle is lower than 40%, the whole vehicle running mode enters the energy-saving mode. Here, the non-energy saving mode includes a normal driving mode in which the entire vehicle power amount can be utilized to the maximum extent to maintain a desired driving state without considering the vehicle power consumption, and a power mode in which the energy saving mode and the power mode are compromised. Since the definitions and standards of the entire vehicle travel patterns of the respective vehicle enterprises are different, the following embodiments are subject to the exemplary description.

In some embodiments, in step S100, the manner of obtaining the predicted mileage of the vehicle may refer to the following steps:

s101, responding to the situation that the vehicle is in a navigation mode, and obtaining the predicted driving mileage according to the distance between the starting position and the end position of the navigation mode;

s101', in response to the fact that the vehicle is not in the navigation mode, obtaining the predicted driving mileage according to a human-computer interaction result, wherein the human-computer interaction result comprises the following steps: the predicted driving mileage selected by the user independently is larger than the first preset value or the predicted driving mileage selected by the user independently is smaller than the first preset value.

In the above steps, the vehicle is in a navigation mode, that is, on a display panel of the vehicle-mounted device system, the user autonomously selects the navigation mode, and the distance between the starting point position and the ending point position on the display panel is used as the predicted driving mileage; for example, when the user does not select the navigation mode of the car machine system, the user may jump out of a selection page on the display panel, where the selection page includes two options, that is, a mileage option greater than the first preset value or a predicted mileage option smaller than the first preset value, and the user needs to manually select the corresponding option, and automatically enter the subsequent thermal management execution method of the present application when selecting the predicted mileage option greater than the first preset value. Further, the display modes of the two options can be referred to as follows: "long-mileage travel", "short-mileage travel"; or other display modes which can take the first preset value as a boundary.

In the step S200, the first preset value may be set by combining various factors such as the attribute of the vehicle itself and the behavior habit of the user, for example, the first preset value is 20km, that is, a boundary line of 20km is defined, a short driving distance is defined between 0km and 20km, and when the vehicle-mounted navigation distance is greater than 20km, the vehicle driving time is longer, which proves that the vehicle is performing long-distance driving. Of course, preset mileage intervals of other numerical values may be set.

In some embodiments, the ambient temperature information corresponds to a preset ambient temperature partition table, the battery pack temperature information corresponds to a preset battery pack temperature partition table, and the preset ambient temperature partition table and the preset battery pack temperature partition table both include a plurality of temperature sections.

Here, for example, the ambient temperature information may be obtained by measuring with a temperature sensor around the vehicle body, or the ambient temperature at the current position may be obtained by positioning the vehicle body with a networked big data platform; the battery pack temperature information refers to the cell temperature in the battery pack 15, and when the cell temperatures in the battery pack 15 are uneven, the temperature value of the cell with the lowest temperature in the battery pack 15 is used as the battery pack temperature information for reference, so that the battery pack 15 with uneven temperature can be heated, the balanced temperature rise of the battery pack 15 can be maintained, and the stable discharge of the battery pack 15 can be facilitated.

Based on the above embodiment, in step S200, the determining a thermal management execution mode according to the ambient environment temperature information or the battery pack temperature information includes:

s201, determining a first temperature interval of the ambient temperature information in the preset ambient temperature partition table, and determining a second temperature interval of the battery pack temperature information in the preset battery pack temperature partition table;

and S202, determining a corresponding thermal management execution mode based on the first temperature interval or the second temperature interval.

In the above steps, the preset environment temperature partition table includes, for example, the following temperature intervals: below-10 deg.C, -10 deg.C to 15 deg.C, above 15 deg.C. When the vehicle is in a temperature range higher than 15 ℃, the temperature information of the battery pack is not too low, so that the heating process of the battery pack 15 is not required to be considered; when the vehicle is in the temperature range of lower than-10 ℃ or between-10 ℃ and 15 ℃, a corresponding execution strategy needs to be adopted by combining the heating requirement of a user and the temperature information of the battery pack. Here, the battery pack temperature information may be displayed by a temperature sensor provided in the battery pack 15, and the battery pack temperature information may be considered as supplementary with the ambient temperature information as a reference, or may be provided with the same temperature section as the ambient temperature information for reference correspondence.

In some embodiments, before step S300, the thermal management execution method further includes:

s300', sending a heat storage execution signal to the control module so that the waste heat recovery pipeline 1 is in a heat storage state, wherein the heat storage state is a state that the waste heat recovery pipeline 1 is not communicated with any pipeline for heat exchange.

In the above steps, the execution logic for sending the heat accumulation execution signal to the control module may refer to the following scenarios:

s301', obtaining test temperature information of a liquid outlet port of the waste heat recovery pipeline 1;

and S302', in response to the fact that the difference value between the test temperature information and the battery pack temperature information is smaller than a second preset value, sending a heat storage execution signal.

In the above steps, for example, the second preset value may be 5 ℃, when the difference between the test temperature information and the battery pack temperature information is less than 5 ℃, the liquid temperature of the waste heat recovery pipeline 1 is substantially the same as the battery pack temperature, and the liquid heat of the waste heat recovery pipeline 1 cannot perform an ideal heating effect on the battery pack 15, so that the waste heat recovery pipeline 1 needs to be in a heat storage state, that is, the high-voltage component is heated after being operated for a period of time, and then the heat storage state is released.

In the above steps, the temperature of the liquid outlet of the waste heat recovery pipeline 1 can be acquired by using a liquid temperature sensor, and since the vehicle is in a long-distance driving state, the temperature of the waste heat recovery pipeline 1 fluctuates within a certain range after increasing along with the increase of the driving time, so that the test temperature information only needs to be acquired in the early period, and when the difference between the test temperature information and the battery pack temperature information is greater than a second preset value, the temperature acquisition work of the liquid outlet of the waste heat recovery pipeline 1 is stopped.

In some embodiments, the heat pump air conditioner 20 is in communication with a vehicle passenger compartment heat exchanger such that the heat pump air conditioner 20 heats or cools the vehicle passenger compartment, and the thermal management implementation method further includes:

and responding to the situation that the passenger compartment of the vehicle is in a heating mode, sending a heating execution signal to the control module so as to enable the heat pump air conditioner 20 to exchange heat with the external environment heat and/or the waste heat recovery pipeline 1 heat.

In the above steps, the heat pump air conditioner 20 may perform heat exchange only by using the external environment, may perform heat exchange by using the heat of the waste heat recovery pipeline 1, may perform heat exchange by using the external environment and the heat of the waste heat recovery pipeline 1 at the same time, and the specific implementation strategy may be determined according to the ambient temperature information.

In some embodiments, the step S300 of providing the first liquid pump 14 on the waste heat recovery pipeline 1, where the execution signal includes flow data of the first liquid pump 14, and sending the execution signal corresponding to the thermal management execution mode to the control module to communicate the waste heat recovery pipeline 1 with the first heat exchange pipeline 2 includes:

s301, sending the execution signal to the first liquid pump 14, so that the first liquid pump 14 adjusts the flow rate of the waste heat recovery pipeline 1 according to the flow rate data corresponding to the execution signal.

In the above steps, the first liquid pump 14 is configured to drive the liquid in the waste heat recovery pipeline 1 to flow back, so that the liquid in the waste heat recovery pipeline 1 forms a complete loop, and the heating efficiency of the waste heat recovery pipeline 1 is adjusted by controlling the flow data of the first liquid pump 14.

Similarly, the second heat exchange pipeline 3 is provided with a second liquid pump 13, the execution signal includes flow data of the second liquid pump 13, and in step S300, the execution signal corresponding to the thermal management execution mode is sent to the control module, so that the waste heat recovery pipeline 1 is communicated with the second heat exchange pipeline 3, including:

s302, sending the execution signal to the second liquid pump 13, so that the second liquid pump 13 adjusts the flow rate of the second heat exchange pipeline 3 according to the flow rate data corresponding to the execution signal.

In the above steps, the second liquid pump 13 is used to drive the liquid in the second heat exchange pipeline 3 to flow back, so that in a scene that the waste heat recovery pipeline 1 and the second heat exchange pipeline 3 are disconnected, the second heat exchange pipeline 3 can still form a complete path with other pipelines through the second liquid pump 13. The regulation of the heating efficiency of the second heat exchange line 3 is achieved by controlling the flow data of the second hydraulic pump 13. Here, for example, the other pipeline may be a heating pipeline 5 connected with a water heating PTC, and in a scenario where the waste heat recovery pipeline 1 and the second heat exchange pipeline 3 are disconnected, the second heat exchange pipeline 3 can still form a complete path with the heating pipeline 5 through the second liquid pump 13.

Furthermore, a parallel pipeline 4 with adjustable on-off is arranged on the second heat exchange pipeline 3, the parallel pipeline 4 is connected in parallel with the second liquid pump 13 and the battery pack 15, and the execution signal comprises adjustment data of the parallel pipeline 4;

the sending of the execution signal corresponding to the thermal management execution mode to the control module to communicate the waste heat recovery pipeline 1 with the second heat exchange pipeline 3 includes:

and sending the execution signal carrying the regulating data to the parallel pipeline 4, and controlling the parallel pipeline 4 to be in a passage state so as to communicate the waste heat recovery pipeline 1 with the second heat exchange pipeline 3.

In the above steps, a stop valve capable of controlling on-off is arranged on the parallel pipeline 4, and the control module is used for controlling on-off of the stop valve to realize control on-off state of the parallel pipeline. The parallel pipeline 4 is arranged, so that the problems of high noise and high energy consumption caused by the fact that the first liquid pump 14 and the second liquid pump 13 work in the state that the waste heat recovery pipeline 1 is communicated with the second heat exchange pipeline 3 can be avoided.

For example, as shown in fig. 2 and fig. 3, the arrow direction in fig. 2 is a heat flow direction, fig. 3 specifically illustrates a logic diagram for determining in a certain driving scenario, and an execution process of a thermal management execution strategy on a thermal management system includes the following scenarios:

(1) The ambient temperature information shows that the ambient temperature is greater than 15 deg.c, or the battery pack temperature information shows that the battery pack temperature is greater than 15 deg.c, at which point the battery pack 15 need not be heated.

(2) The ambient temperature information shows that the ambient temperature is-10 ℃ to 15 ℃, a user starts warm air to meet the heating requirement, the battery pack temperature information shows that the temperature of the battery pack is lower than 15 ℃, at the moment, the waste heat recovery pipeline 1 is communicated with the first heat exchange pipeline 2, the heat pump air conditioner 20 exchanges heat with the waste heat recovery pipeline 1 and supplies heat to the passenger compartment, and the battery pack 15 is not heated; when the temperature in the passenger cabin is higher than 15 ℃, the connection between the waste heat recovery pipeline 1 and the first heat exchange pipeline 2 is disconnected, and the heat pump air conditioner 20 continues to heat the passenger cabin through external environment heat exchange.

(3) The ambient temperature information shows that the ambient temperature is-10 ℃ to 15 ℃, a user has no heating requirement or the temperature of a passenger cabin is more than 15 ℃, whether the difference value between the test temperature information and the temperature information of the battery pack is more than 5 ℃ is judged, when the difference value is more than 5 ℃, the waste heat recovery pipeline 1 is communicated with the second heat exchange pipeline 3, the high-pressure part generates heat to heat the battery pack 15, the first liquid pump 14 operates at a duty ratio of 60%, the second liquid pump 13 does not operate, the parallel pipeline 4 is in a passage state until the temperature information of the battery pack shows that the temperature of the battery pack is more than 15 ℃ or the waste heat recovery pipeline 1 and the second heat exchange pipeline 3 are disconnected after the driving is finished.

(4) The ambient temperature information shows that the ambient temperature is lower than-10 ℃, if the user does not start the warm air, the user pays more attention to the driving range of the vehicle in the scene, at the moment, the difference value between the test temperature information and the temperature information of the battery pack is judged, when the difference value is higher than 5 ℃, the waste heat recovery pipeline 1 is communicated with the second heat exchange pipeline 3, when the difference value is lower than 5 ℃, the waste heat recovery pipeline 1 is required to enter a heat storage state, at the moment, the waste heat recovery pipeline 1 is communicated with the first heat exchange pipeline 2, but the heat pump air conditioner 20 does not exchange heat with the waste heat recovery pipeline 1, only the waste heat recovery pipeline 1 realizes the function of a complete circulation path, when the vehicle runs for a period of time and the difference value is higher than 5 ℃, the waste heat recovery pipeline 1 is communicated with the second heat exchange pipeline 3 to heat the battery pack 15, and the heating mode can refer to the execution mode of the scene (3).

(5) In the scenario (4), when the waste heat recovery pipeline 1 enters the heat storage state, the waste heat recovery pipeline 1 is communicated with the heating pipeline 5, but the water heating PTC does not work, and only the heating pipeline 5 and the waste heat recovery pipeline 1 form a complete loop.

(6) The ambient temperature information shows that the ambient temperature is lower than-10 ℃, a user starts hot air with a heating requirement, the waste heat recovery pipeline 1 is communicated with the first heat exchange pipeline 2, and the heat pump air conditioner 20 performs heat exchange with the waste heat recovery pipeline 1 to supply heat to the passenger compartment; in the process, the difference value between the temperature of the liquid outlet port of the first heat exchange pipeline 2 and the temperature information of the battery pack is continuously detected, and the waste heat recovery pipeline 1 is communicated with the second heat exchange pipeline 3 when the difference value is larger than 5 ℃, so that the waste heat recovery pipeline 1 heats the battery pack 15.

It should be noted that the difference between the temperature of the liquid outlet port of the first heat exchange pipeline 2 and the temperature information of the battery pack is greater than 5 ℃, which proves that after the liquid in the waste heat recovery pipeline 1 is subjected to heat exchange through the first heat exchange pipeline 2, the temperature of the liquid in the pipeline is still higher than the temperature of the battery pack, and the liquid with relatively high temperature can continue to heat the battery pack 15, so that the energy utilization effect is further improved. Of course, the first preset value is only illustrated by way of example, and may be 4 ℃, 6 ℃ or the like.

In the above embodiment, the actually adopted thermal management execution strategies are different according to different actual scenarios, but the core idea is as follows: the liquid in the waste heat recovery pipeline 1 is utilized as much as possible to heat the passenger compartment of the first heat exchange pipeline 2 or the battery pack 15 of the second heat exchange pipeline 3, and the battery pack 15 is heated in a gradient heating mode according to different reference temperatures.

Because the temperature rise of battery package 15 is favorable to the promotion of battery package 15 discharge capacity, under long mileage driving state, battery package 15 self heat can rise, nevertheless when battery package temperature heating to a certain extent, can not bring the profit for the promotion of whole continuation of the journey for its electric quantity that heats consumption, need the focus to optimize air conditioning system energy consumption this moment. This setting can be great degree reduce the thermal invalid of vehicle itself and spill over to with the heat cyclic utilization that the vehicle produced, effectively promoted the energy utilization effect of vehicle, practice thrift the vehicle energy, promote vehicle continuation of the journey.

The method of the embodiment can also be applied to a distributed scene and is completed by the mutual cooperation of a plurality of devices. In such a distributed scenario, one of the multiple devices may only perform one or more steps of the method of the embodiment, and the multiple devices interact with each other to complete the method.

The apparatus of the foregoing embodiment is used to implement the corresponding thermal management execution method in any of the foregoing embodiments, and has the beneficial effects of the corresponding method embodiment, which are not described herein again.

Based on the same inventive concept, the application also provides a thermal management system, and the system can be used for executing the thermal management execution method.

As shown in fig. 5, the heat management system of the present application includes a waste heat recovery pipeline 1, a first heat exchange pipeline 2, a second heat exchange pipeline 3, and a reversing valve 9, wherein a high-pressure component heat exchanger 7 is disposed on the waste heat recovery pipeline 1; the first heat exchange pipeline 2 is provided with a battery cooler 10 and a heat pump air conditioner 20 in series; a second liquid pump 13 and a battery pack 15 are arranged on the second heat exchange pipeline 3 in series; the reversing valve 9 is used for communicating at least two of the first heat exchange pipeline 2, the second heat exchange pipeline 3 and the waste heat recovery pipeline 1 for heat exchange.

As can be seen from the above, in the heat management system provided by the application, the reversing valve 9 is arranged between the waste heat recovery pipeline 1, the first heat exchange pipeline 2 and the second heat exchange pipeline 3, and the reversing valve 9 is used for communicating at least two of the first heat exchange pipeline 2, the second heat exchange pipeline 3 and the waste heat recovery pipeline 1 for heat exchange, so that interference conflict between the waste heat recovery pipeline 1 and the first heat exchange pipeline 2 and the work of the second heat exchange pipeline 3 when heat exchange is performed, and interference conflict between the waste heat recovery pipeline 1 and the work of the first heat exchange pipeline 2 when heat exchange is performed between the waste heat recovery pipeline 1 and the second heat exchange pipeline 3 are avoided;

in addition, because the inlet temperature of battery package 15 has certain restriction, the liquid in the waste heat recovery pipeline 1 that surpasss the inlet temperature restriction can form the heat exchange with heat pump air conditioner 20 via first heat transfer pipeline 2 to make the outlet temperature of waste heat recovery pipeline 1 unrestricted, thermal waste heat utilization rate in the waste heat recovery pipeline 1 can more effectual promotion.

It should be noted that the aforementioned high-pressure component heat exchanger 7 is a heat exchanger connected to a high-pressure component, where the high-pressure component refers to a vehicle body related component such as a motor and an electric control device, and these components continuously generate heat in a working state, the generated heat is conveyed to the waste heat recovery pipeline 1 through the high-pressure component heat exchanger 7, and the heat is subsequently utilized by the heat pump air conditioner 20 or the battery pack 15, so as to improve a waste heat recovery effect of the vehicle.

In addition, the heat pump air conditioner 20 and the battery cooler 10 (chiller) both mentioned in the present embodiment may employ a heat exchange device of a vehicle well-known in the art. In some embodiments, the thermal management system further comprises a control module, the control module is electrically connected with the reversing valve, and the control module can control the valve port of the reversing valve to be switched to a connection and disconnection state, so that the pipelines are connected or disconnected under the control of the control module.

In some embodiments, as shown in fig. 5, the thermal management system further comprises a heating pipeline 5, a heating element 18 is disposed on the heating pipeline 5, and the heating pipeline 5 can communicate with the second heat exchange pipeline 3 through the reversing valve 9. Here, the heating element 18 may employ a water heating PTC (Positive Temperature coefficient thermistor) device, and the heating element 18 can convert electric energy into heat energy, thereby inputting high-power heat to the battery pack 15.

As can be seen from fig. 5, the liquid outlet end of the heating pipeline 5, the waste heat recovery pipeline 1 and the second heat exchange pipeline 3 are connected through a tee joint, the liquid inlet end of the heating pipeline 5 is connected with the reversing valve 9, and the circulation loop of the heating pipeline 5 and the second heat exchange pipeline 3 is realized by switching the valve port of the reversing valve 9.

Further, the heat management system also comprises a passenger compartment pipeline 6, and the heating element 18, the passenger compartment heat exchanger 19 and the heat pump air conditioner 20 are arranged on the passenger compartment pipeline 6 in series, so that when the temperature of the passenger compartment of the vehicle is low, the heating element 18 inputs high-power heat to the passenger compartment heat exchanger 19, and the temperature of the passenger compartment of the vehicle is ensured. The passenger compartment heat exchanger 19 is used to communicate with an air outlet of the passenger compartment in order to supply cold or hot air to the passenger compartment. Because the heating element 18, the passenger compartment heat exchanger 19 and the heat pump air conditioner 20 are arranged in series, the heat pump air conditioner 20 and the heating element 18 can simultaneously do work on the passenger compartment heat exchanger 19, so that different scenes that only the heat pump air conditioner 20 is started in a low-temperature environment or the heat pump air conditioner 20 and the heating element 18 are started in a lower-temperature environment can be flexibly selected, and the heat utilization maximization of a vehicle is ensured.

In the above embodiment, since the heat pump air conditioner 20 has a low temperature requirement on the outlet side of the waste heat recovery pipeline 1, the upper temperature limit on the outlet side of the high-pressure component may not be set, so that the waste heat of the waste heat recovery pipeline 1 is more fully utilized, and the heat storage process of the driving system may also be omitted.

Further, as shown in fig. 5, the heating pipeline 5 is connected in parallel with the second heat exchange pipeline 3 and the passenger compartment pipeline 6, so that the heating element 18 can input heat to the battery pack 15 on one hand and can also input heat through the passenger compartment heat exchanger 19 on the other hand, the heat and the heat do not interfere with each other, the heating can be implemented independently or simultaneously, and the use scene of the heating element 18 can be expanded.

In some embodiments, a parallel pipeline 4 is further disposed on the second heat exchange pipeline 3, the parallel pipeline 4 is connected in parallel with the second hydraulic pump 13 and in series with the battery pack 15, and the waste heat recovery pipeline 1 can be connected with the battery pack 15 through the parallel pipeline 4. From this, when the heat of waste heat recovery pipeline 1 was enough to satisfy the heating demand of battery package, can adopt parallel pipeline 4 to avoid second liquid pump 13 to reduce second liquid pump 13's frequency of use, be favorable to further promoting energy utilization.

In the above embodiment, the parallel pipeline 4 may be provided with the first stop valve 16 to control the on-off state thereof, when the first stop valve 16 is opened, because the parallel pipeline 4 is arranged in parallel with the second liquid pump 13, in a state where the second liquid pump 13 is not operated, the liquid carrying the residual heat of the high-pressure component circulates from the parallel pipeline 4 with smaller resistance to the battery pack; when the first shut-off valve 16 is closed, the parallel line 4 is disconnected and fluid can only flow through the battery pack by the second fluid pump 13.

As shown in fig. 5, in some embodiments, the thermal management system further includes a heat dissipation pipeline 21, a heat dissipation member 22 is disposed on the heat dissipation pipeline 21, and the waste heat recovery pipeline 1 is communicated with the heat dissipation pipeline 21 via the directional valve 9, so that when heat generated by the high-pressure component is too high, the heat can be dissipated to the outside of the vehicle body through the heat dissipation member 22, and the high-pressure component is prevented from being continuously at a high temperature and affecting the service life.

In some embodiments, a first temperature sensor 8 is disposed at a liquid outlet side of the waste heat recovery pipeline 1, and a second temperature sensor 11 is disposed at a liquid outlet side of the first heat exchange pipeline 2. Can monitor waste heat recovery pipeline 1's liquid outlet temperature through first temperature sensor 8, can monitor second heat transfer pipeline 3's liquid outlet temperature through setting up second temperature sensor 11, this setting can be convenient for accuse heat temperature to be favorable to setting for reasonable logic command and realize thermal cyclic utilization. Here, a temperature sensor for detecting the battery core should be further provided on the battery pack, and the temperature sensor may be implemented by using an existing mature technology, which is not described in this embodiment again.

In the above embodiment, the waste heat recovery pipeline 1 is provided with the first liquid pump 14, and one side of the liquid inlet of the waste heat recovery pipeline 1 is connected to the first heat exchange pipeline 2, the second heat exchange pipeline 3 and the heat dissipation pipeline 21 through the connecting component 12. Illustratively, the connector 12 may be implemented as a conventional four-way valve or other fluid valve capable of multiple connections. Here, the first liquid pump 14 can be arranged to deliver the residual heat of the high-pressure components to the heat pump air conditioner 20 and the passenger compartment heat exchanger 19, and also to deliver the residual heat of the high-pressure components to the battery pack through the parallel pipeline 4 on the premise of avoiding the second liquid pump 13, so that the use effect of the first liquid pump 14 is effectively improved; the connecting piece 12 is arranged, so that the structural connection difficulty can be greatly reduced, and the simple and reliable connection structure is ensured.

As shown in fig. 5, in some embodiments, a second stop valve 17 is further disposed between the waste heat recovery pipeline 1 and the second heat exchange pipeline 3, and the second stop valve 17 can control an on-off state of the second heat exchange pipeline 3, so as to prevent liquid of the second heat exchange pipeline 3 from flowing back to affect normal heat exchange.

It should be noted that the aforementioned reversing valve 9 may adopt a five-way valve to realize the switching state between the pipelines, and when the five-way valve is adopted, it has one input port and four output ports, the waste heat recovery pipeline 1 is used as the input port, and is respectively connected with the heat dissipation pipeline 21, the heating pipeline 5, the first heat exchange pipeline 2, and the second heat exchange pipeline 3, and the connection or disconnection state of the waste heat recovery pipeline 1 and different pipelines is realized by switching the valve port position of the five-way valve.
