Embodiments of the present application are described in detail below with reference to the accompanying drawings.

In one or more embodiments of the present application, a thermal management execution strategy 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 7, 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, and the control module can regulate and control connection states of the waste heat recovery pipeline, the first heat exchange pipeline, and the second heat exchange pipeline.

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

s100, responding to the situation 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 smaller than a first preset value, obtaining vehicle temperature information, and determining a thermal management execution mode according to the vehicle temperature information;

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

As can be seen from the above description, according to the thermal management execution strategy provided by the present application, when the vehicle is in the energy saving mode, the thermal management execution mode is determined according to the vehicle 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 delivered to the heat pump air conditioner 20 for use, and 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 delivered to the battery pack 15 for use.

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 7 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 electric control device, and these vehicle body related parts can continuously generate heat in a working state, and the generated heat is conveyed to the waste heat recovery pipeline 11 through the high-pressure part heat exchanger 7, and through the aforementioned heat 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.

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

In some embodiments, as shown in fig. 2, in step S100, obtaining the predicted mileage of the vehicle in response to the vehicle being in the energy saving mode includes:

s101, acquiring a whole vehicle running mode, wherein the whole vehicle running mode comprises an energy-saving mode and a non-energy-saving mode;

s102, responding to the situation that the vehicle is in an energy-saving mode, and obtaining the predicted driving mileage of the vehicle according to a vehicle navigation mode or a man-machine interaction result; 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.

The steps are all carried out when the vehicle is in a starting state, the mode of acquiring the running mode of the whole vehicle can be that a user manually selects an energy-saving mode after starting the vehicle, and can also be automatically adjusted to the energy-saving mode according to the electric quantity of the vehicle, and for example, when the electric quantity of the vehicle is lower than 30%, the running mode of the whole vehicle 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 overall driving mode definitions and standards of the various enterprises are different, the following embodiments are subject to the exemplary explanation.

In some embodiments, for example, the obtained predicted driving mileage of the vehicle may be determined by a mileage of a car navigation started by a user, and the predicted driving mileage is obtained according to a distance between a start position and an end position of the navigation mode; when the user does not select the car navigation system, the user can jump to a selection interface through a human-computer interaction page, and the user selects whether to drive in long mileage or in short mileage; and when the vehicle is determined to be in the energy-saving mode and the vehicle is in the short-distance driving state, executing the thermal management execution strategy.

In step S103, the preset mileage interval may be set by combining various factors such as the attribute of the vehicle itself and the behavior habits of the user, for example, the first preset value may be 20km, that is, 20km is used as a boundary, and when the obtained predicted mileage is less than 20km, the vehicle running time is short, which proves that the vehicle runs with a short mileage. Of course, preset mileage intervals of other numerical values may be set.

In some embodiments, the vehicle temperature information includes ambient temperature information and battery pack temperature information, wherein 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 zones.

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 temperature in the battery pack 15 is 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 is also heated, the balanced temperature rise of the battery pack 15 is kept, and the stable discharge of the battery pack 15 is facilitated.

Based on the above embodiment, in step S200, the determining a thermal management execution mode according to the vehicle temperature information includes:

s204, 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 S205, determining a corresponding thermal management execution mode based on the first temperature interval and the second temperature interval.

In the above steps, the preset environment temperature partition table includes, for example, the following temperature intervals: below-20 deg.C, -20 deg.C to 15 deg.C, above 15 deg.C. The first temperature interval determined according to the ambient temperature information should be one of the temperature intervals. 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 interval of lower than-20 ℃ or-20 ℃ to 15 ℃, the corresponding execution strategy is required to be adopted according to the heating requirement of the 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 to be supplemented with ambient temperature information, where the second temperature zone is one of a plurality of temperature zones in the preset battery pack temperature partition table.

For example, as shown in fig. 3 and 4, the arrow direction in fig. 3 is a heat flow direction, fig. 4 specifically illustrates a judgment logic block diagram in a certain driving scenario, and the execution process of the thermal management execution policy on the thermal management system includes the following scenarios:

(1) The collected ambient temperature information is between minus 20 ℃ and 15 ℃, the user opens the warm air to meet the heating requirement, the temperature information of the battery pack shows that the temperature of the battery pack is lower than 0 ℃, at the moment, the waste heat recovery pipeline 1 is communicated with the first heat exchange pipeline 2, the heat in the waste heat recovery pipeline 1 is transmitted to the heat pump air conditioner 20 through the first heat exchange pipeline 2, and therefore the heat pump air conditioner 20 transmits the heat to the passenger cabin.

(2) The collected ambient temperature information is between-20 ℃ and 15 ℃, a user opens a warm air to meet the heating requirement, the temperature information of the battery pack shows that the temperature of the battery pack 15 is lower than 0 ℃, at the moment, the waste heat recovery pipeline 1, the first heat exchange pipeline 2 and the second heat exchange pipeline 3 are communicated, part of heat in the waste heat recovery pipeline 1 is conveyed to the heat pump air conditioner 20 through the first heat exchange pipeline 2, and part of heat is conveyed to the battery pack 15 through the second heat exchange pipeline 3 to heat the battery pack 15.

(3) The collected ambient temperature information is between-20 ℃ and 15 ℃, a user does not have heating requirements, but the temperature information of the battery pack shows that the temperature of the battery pack 15 is lower than 0 ℃, at the moment, the waste heat recovery pipeline 1 is communicated with the second heat exchange pipeline 3, and heat in the waste heat recovery pipeline 1 is conveyed to the battery pack 15 through the second heat exchange pipeline 3 to heat the battery pack 15.

(4) The collected ambient temperature information is higher than 15 ℃, and the battery pack 15 and the passenger compartment are not heated in the energy-saving mode and the short-distance driving scene.

In each of the above scenarios, further, a temperature sensor is further disposed at a liquid outlet end of the first heat exchange pipeline 2 for detecting a liquid temperature in the pipeline, in the step S300, the sending an 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:

s301, obtaining test temperature information of a liquid outlet port of the first heat exchange pipeline 2;

s302, responding to the fact that the difference value between the test temperature information and the battery pack temperature information is larger than a first preset value, and sending out an execution signal.

In the above steps, the obtained difference between the test temperature information and the battery pack temperature information may be used as a reference factor to comprehensively consider the execution state, for example, the first preset value is 5 ℃, and the difference between the test temperature information and the battery pack temperature information is greater than 5 ℃, which proves that after the liquid in the waste heat recovery pipeline 1 is subjected to heat exchange via the first heat exchange pipeline 2, the temperature of the liquid in the pipeline is still higher than the temperature of the battery pack 15, and the relatively high-temperature liquid can continue to heat the battery pack 15, thereby further improving the energy utilization effect. Of course, the first preset value is only illustrated by way of example, and may be 4 ℃, 6 ℃ or the like.

For example, in the foregoing scenario (2), the collected ambient temperature information is between-20 ℃ and 15 ℃, the user opens a heating demand when warm air has been supplied, the difference between the test temperature information and the battery pack temperature information is greater than 5 ℃, at this time, the waste heat recovery pipeline 1, the first heat exchange pipeline 2 and the second heat exchange pipeline 3 are all communicated, a part of heat in the waste heat recovery pipeline 1 is delivered to the heat pump air conditioner 20 through the first heat exchange pipeline 2, and a part of heat is delivered to the battery pack 15 through the second heat exchange pipeline 3 to heat the battery pack 15; when the difference between the test temperature information and the battery pack temperature information is less than 5 ℃, the waste heat recovery pipeline 1 can be communicated with the first heat exchange pipeline 2 only for heat exchange.

For example, in the foregoing scenario (3), the collected ambient temperature information is at-20 ℃ to 15 ℃, the user has no heating requirement, and can directly determine the difference between the test temperature information and the battery pack temperature information, and when the difference is greater than 5 ℃, the waste heat recovery pipeline 1 is communicated with the second heat exchange pipeline 3, so that the liquid in the waste heat recovery pipeline 1 heats the battery pack 15.

In some embodiments, the thermal management system of the vehicle further comprises a heating circuit 5 connected to the heating element 18, and the heating element 18 may be a water heating PTC device as is well known in the art, or other related devices for converting electrical energy into heat energy.

Based on the heating pipeline 5 in the above embodiment, the thermal management execution strategy of the present application further includes:

s400, obtaining ambient environment temperature information;

and S500, responding to the condition that the ambient temperature information is less than a second preset value, sending an execution signal to the control module so as to enable the heating pipeline 5 to be communicated with the first heat exchange pipeline 2 and/or the second heat exchange pipeline 3.

In the above embodiment, for example, the second preset value may be-20 ℃, and when the ambient temperature information is lower than-20 ℃, the execution scenario of the thermal management execution policy on the thermal management system includes the following scenarios:

(5) The ambient temperature information is lower than-20 ℃, a user actively starts the heating function of the battery pack 15, in this scene, although the battery pack is in an energy-saving mode, the user still needs strong vehicle power to drive, at the moment, the heating pipeline 5 is communicated with the first heat exchange pipeline 2 and the second heat exchange pipeline 3, the heating element 18 heats the battery pack 15, and the heating pipeline 5 and the second heat exchange pipeline 3 are disconnected when the temperature information of the battery pack is-10 ℃; in the process, the temperature of the heating pipeline 5 to the passenger compartment of the first heat exchange pipeline 2 is kept above 0 ℃ so as to ensure the basic driving experience of users.

(6) The ambient temperature information is lower than-20 ℃, but is influenced by the electric quantity of the vehicle, a user does not actively start the heating function of the battery pack 15, and on the premise, when the difference between the test temperature information and the battery pack temperature information is detected to be greater than 5 ℃, the waste heat recovery pipeline 1 is communicated with the second heat exchange pipeline 3, so that the liquid of the waste heat recovery pipeline 1 heats the battery pack 15; in the process, if a user has a heating demand, the heating pipeline 5 is communicated with the first heat exchange pipeline 2, so that the heating element 18 heats the passenger compartment to be more than 0 ℃, then the waste heat recovery pipeline 1 is communicated with the first heat exchange pipeline 2, and the liquid of the waste heat recovery pipeline 1 is used for heating the passenger compartment.

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 cabin of the first heat exchange pipeline 2 or the battery pack 15 of the second heat exchange pipeline 3, and the heating pipeline 5 is adopted to heat the passenger cabin of the first heat exchange pipeline 2 or the battery pack 15 of the second heat exchange pipeline 3 on the premise that the liquid in the waste heat recovery pipeline 1 cannot be heated sufficiently. 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.

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:

s303, 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 S200, 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:

s303', 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 the second heat exchange pipeline 3 can still form a complete passage with the heating pipeline 5 through the second liquid pump 13 in a scene that the waste heat recovery pipeline 1 and the second heat exchange pipeline 3 are disconnected. The adjustment of the heating efficiency of the second heat exchange pipeline 3 is realized by controlling the flow data of the second hydraulic 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 hydraulic pump 13 and the battery pack 15, and the execution signal comprises adjustment data of the parallel pipeline;

the sending of the execution signal corresponding to the thermal management execution mode to the control module to communicate the waste heat recovery pipeline 13 with the second heat exchange pipeline 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 to control 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.

Illustratively, the adjustment of the flow data of the first liquid pump 14 may be achieved by adjusting a duty cycle of the first liquid pump 14, and the adjustment of the flow data of the second liquid pump 13 may be achieved by adjusting a duty cycle of the second liquid pump 13. For example, in the scenario (1), since the ambient temperature is not in the extremely low state below-20 ℃, in this scenario, the first liquid pump 14 may be controlled to operate at a 50% duty cycle, the second liquid pump 13 is not operated, the stop valve controls the parallel pipeline 4 to be opened, and only the first liquid pump 14 is used for pumping circulation of the liquid.

For another example, in the scene (2), since the waste heat recovery pipeline 1 is communicated with the first heat exchange pipeline 2 and the second heat exchange pipeline 3, the first liquid pump 14 can be controlled to operate at a duty ratio of 60%, the second liquid pump 13 can be controlled to operate at a duty ratio of 40%, and the stop valve controls the parallel pipeline 4 to be disconnected.

For another example, in the scene (3), since the waste heat recovery pipeline 1 is communicated with the second heat exchange pipeline 3, the first liquid pump 14 can be controlled to operate at a duty ratio of 60%, and the parallel pipeline 4 is controlled to be closed by the stop valve.

For another example, in a scene (5), the heating pipeline 5 is communicated with both the first heat exchange pipeline 2 and the second heat exchange pipeline 3, and in this scene, the stop valve controls the parallel pipeline 4 to be disconnected, and controls the second hydraulic pump 13 to operate at 50% duty ratio.

For another example, in the scene (6), the waste heat recovery pipeline 1 is communicated with the second heat exchange pipeline 3, at this time, the first liquid pump 14 is controlled to operate at a duty ratio of 60%, and the second liquid pump 13 is controlled to be closed.

In the above embodiments, the operation duty ratios of the first liquid pump 14 and the second liquid pump 13 are only exemplified, and the actual adjustment parameters thereof can be flexibly adjusted according to the driving state of the vehicle.

Through the arrangement, different thermal management execution strategies can be flexibly selected according to different demand scenes of users, user-defined is supported, and vehicle energy consumption and driving requirements are effectively balanced.

It should be noted that the method of the embodiment of the present application may be executed by a single device, such as a computer or a server.

In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.

Based on the same inventive concept, the application also provides a thermal management device corresponding to the method of any embodiment.

Referring to fig. 5, the thermal management device includes:

a sensing module 23 configured to acquire a predicted driving range of the vehicle in response to the vehicle being in an energy saving mode;

the data processing module 24 is configured to respond to the predicted driving mileage being smaller than a first preset value, acquire vehicle temperature information, and determine a thermal management execution mode according to the vehicle temperature information;

For convenience of description, the above devices are described as being divided into various modules by functions, and are described separately. Of course, the functionality of the various modules may be implemented in the same one or more pieces of software and/or hardware in the practice of the present application.

The apparatus in the foregoing embodiment is used to implement the corresponding thermal management execution policy 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 which can be used for executing the thermal management execution strategy.

As shown in fig. 6, the heat management system described in 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 high-pressure part heat exchanger 7 is a heat exchanger connected to a high-pressure part, where the high-pressure part is a vehicle body related part such as a motor and an electric control device, and the parts can continuously generate heat in an operating state, the generated heat is conveyed to the waste heat recovery pipeline 1 through the high-pressure part 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, both the heat pump air conditioner 20 and the battery cooler 10 (chi l er) mentioned in the present embodiment may employ a heat exchange device of a vehicle well-known in the art.

In some embodiments, as shown in fig. 6, 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 be a water heating PTC (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. 6, the liquid outlet end of the heating pipeline 5, the waste heat recovery pipeline 1 and the second heat exchange pipeline 3 are connected by a tee joint, the liquid inlet end of the heating pipeline 5 is connected with the reversing valve 9, and the valve port of the reversing valve 9 is switched to realize the circulation loop of the heating pipeline 5 and the second heat exchange pipeline 3.

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. 6, 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, which do not interfere with each other, and can be implemented separately or simultaneously, thereby expanding the usage scenario of the heating element 18.

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 to 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 does not work, the liquid carrying the waste 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. 6, 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 the liquid outlet temperature of waste heat recovery pipeline 1 through first temperature sensor 8, can monitor the liquid outlet temperature of second heat transfer pipeline 3 through setting up second temperature sensor 11, this setting can be convenient for the accuse heat temperature to be favorable to setting for reasonable logic command and realize thermal cyclic utilization. Here, a temperature sensor for detecting the electric core should be further disposed 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 respectively connected with the first heat exchange pipeline 2, the second heat exchange pipeline 3 and the heat dissipation pipeline 21 through the connecting piece 12. Illustratively, the connector 12 may be a 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. 6, 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 the 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 a switching state between the pipelines, and when the five-way valve is adopted, it has one input port and four output ports, and the waste heat recovery pipeline 1 is used as the input port and is respectively connected to the heat dissipation pipeline 21, the heating pipeline 5, the first heat exchange pipeline 2, and the second heat exchange pipeline 3, and by switching the valve port position of the five-way valve, a connection or disconnection state between the waste heat recovery pipeline 1 and different pipelines is realized.

The following describes the thermal management system of the present application in several exemplary application scenarios, where an arrow direction indicates a flow direction of liquid, a dark line represents a related pipeline that is working at this time, a light line represents a related pipeline that does not form a passage at this time, ports of the reversing valve 9 are respectively denoted by a, b, c, d, and e, the port a is correspondingly connected to the waste heat recovery pipeline 1, the port b is correspondingly connected to the heat dissipation pipeline 21, the port c is correspondingly connected to the heating pipeline 5, the port d is correspondingly connected to the first heat exchange pipeline 2, and the port e is correspondingly connected to the second heat exchange pipeline 3.

As shown in fig. 7 to 12, in some embodiments, the implementation process of the thermal management system corresponding to the foregoing thermal management implementation policy includes the following scenarios:

(1) As shown in fig. 7, when the vehicle body senses that the ambient temperature is low, the passenger compartment has a heating demand, but when the cell temperature of the battery pack is still within an acceptable range, only the port ad in fig. 2 may be communicated, at this time, the heat generated by the high-voltage component is transmitted to the battery cooler 10 through the waste heat recovery pipeline 1 and the port d, and the heat pump air conditioner 20 receives the heat through the battery cooler 10 and transmits the heat to the passenger compartment heat exchanger 19, and transmits the heat to the passenger compartment through the passenger compartment heat exchanger 19 to realize heating in the passenger compartment.

(2) As shown in fig. 8, in some embodiments, for example, when the vehicle body senses that the environmental temperature is low, the temperature of the battery cell of the battery pack needs to be low, the first temperature sensor 8 detects and obtains the temperature value of the waste heat recovery pipeline 1, and when the temperature value is 4 ℃ -6 ℃ higher than the lowest temperature value allowed by the battery cell of the battery pack, it is proved that the liquid passing through the waste heat recovery pipeline 1 alone can realize the battery cell heating of the battery pack, at this time, the first liquid pump 14 is opened, and controls the ae port of the reversing valve 9 to communicate, and controls the second stop valve 17 to open to form a passage, the first stop valve 16 is opened to form a passage, the waste heat recovery pipeline 1 and the second heat exchange pipeline 3 form a passage, and the liquid is directly conveyed to the battery pack 15 via the parallel pipeline 4 to supply heat to the battery cell of the battery pack.

(3) As shown in fig. 9, in some embodiments, for example, long distance driving causes more heat generated by high-voltage components of the vehicle body, the heat pump air conditioner 20 may absorb waste heat of the high-voltage components, and may support heating of the passenger compartment, and the residual heat of the high-voltage components may be left, and at this time, the battery pack may be heated at the same time. If the temperature value of the liquid passing through the heat pump air conditioner 20 is monitored by the second temperature sensor 11, when the temperature value is 4-6 ℃ higher than the lowest temperature value allowed by the electric core of the battery pack, it is proved that the residual heat of the liquid passing through the heat pump air conditioner 20 can heat the electric core of the battery pack, at this time, the aec port of the reversing valve 9 is communicated, the second liquid pump 13 and the first liquid pump 14 are both opened, the first stop valve 16 is closed to form an open circuit, the second stop valve 17 is opened to form a passage, the liquid in the residual heat recovery pipeline 1 is firstly conveyed to the first heat exchange pipeline 2 through the ad port to exchange heat with the heat pump air conditioner 20, the liquid passing through the battery cooler 10 is conveyed to the battery pack 15 through the four-way and the second heat exchange pipeline 3, and therefore the electric core of the battery pack is heated.

In the above embodiments, the difference between the temperature value of the waste heat recovery pipeline 1 monitored by the first temperature sensor 8 and the lowest temperature value allowed by the battery core may be set by combining multiple reference factors, and the difference between the temperature value of the waste heat recovery pipeline 1 monitored by the second temperature sensor 11 and the lowest temperature value allowed by the battery pack battery core may be set by combining multiple reference factors, for example, according to the usage scenario of the battery pack, the thermal insulation performance of the battery pack itself, and the like.

(4) As shown in fig. 10, in some embodiments, for example, when the vehicle body senses that the ambient temperature is low, the heat of the waste heat recovery pipeline 1 is insufficient to heat the battery pack, at this time, the ad port of the reversing valve 9 is communicated, the ec port is communicated, the second liquid pump 13 and the first liquid pump 14 are opened, the first stop valve 16 is opened to form a passage, and the second stop valve 17 is closed to form an open circuit, in this state, on one hand, the liquid in the waste heat recovery pipeline 1 is conveyed to the first heat exchange pipeline 2 through the communicated ad port, so that the heat pump air conditioner 20 absorbs the heat and conveys the heat to the passenger compartment heat exchanger 19 to heat the passenger compartment, on the other hand, because the second stop valve 17 is closed, the heating pipeline 5 and the second heat exchange pipeline 3 are communicated, and the heating element 18 can heat the liquid in the second heat exchange pipeline 3, so that the circulation passage of the liquid among the battery pack 15, the reversing valve 9 and the heating pipeline 5 is realized under the pumping action of the second liquid pump 13, and because the heating power of the heating element 18 is high, the battery pack in this state can be heated quickly, thereby ensuring the normal driving effect.

(5) As shown in fig. 11, in some embodiments, for example, when the vehicle body senses that the ambient temperature is high, the heat of the waste heat recovery pipeline 1 can be directly utilized to supply heat to the battery pack 15, and the heat pump air conditioner 20 directly exchanges heat with the ambient environment to realize heat supply to the passenger compartment, where ae ports of the reversing valve 9 are communicated, that is, only the waste heat recovery pipeline 1 and the second heat exchange pipeline 3 are communicated, the first stop valve 16 is opened to form a passage, the second stop valve 17 is opened to form a passage, and the liquid in the waste heat recovery pipeline 1 is conveyed to the battery pack 15 through the reversing valve 9 and flows back to the waste heat recovery pipeline 1 through the four-way.

(6) Alternatively, as shown in fig. 12, in some embodiments, for example, when the vehicle body senses that the ambient temperature is high, the heat pump air conditioner 20 may directly exchange heat with the ambient environment to supply heat to the passenger compartment, and in order to rapidly heat up the battery pack, the ec port may be communicated, and at this time, the heating pipeline 5 is communicated with the second heat exchange pipeline 3, and the heating element 18 of the heating pipeline 5 is used to deliver heat to the battery pack 15.

In the above embodiment, the valve port of the reversing valve is switched to implement the execution action of the thermal management execution strategy.

In the above embodiment, the operation of heating the battery pack may also be applied to the case where the temperatures of the different battery cells of the battery pack are different, that is, in order to keep the battery cells of the battery pack at the uniform temperature, the operation of heating the battery pack is adopted.
