Description

TECHNICAL FIELD

[0001] The present application relates to an integrated thermal management system of a vehicle, which can effectively manage energy required for internal air conditioning, electronic device cooling, or battery cooling / heating in the field of vehicle thermal management. BACKGROUND

[0002] In recent years, the implementation of environmental protection technology and solutions such as energy depletion problems have become social problems related to electric vehicles. Electric vehicles are driven by electric motors that output power by being powered by batteries. Accordingly, electric vehicles have the advantages of not emitting carbon dioxide, producing less noise, and having higher energy efficiency of electric motors than energy efficiency of engines, so electric vehicles are attracting attention as environmentally friendly vehicles.

[0003] The core technology to realize such an electric vehicle is a technology related to a battery module, and in recent years, research has been actively conducted to reduce the weight and volume of the battery and to shorten the charging time. When the battery module is used in an optimal temperature environment, it can maintain optimal performance and a long service life. However, it is substantially difficult to use the battery module in an optimal temperature environment due to heat generated during operation and changes in external temperature.

[0004] In addition, electric vehicles do not have waste heat generated by combustion in a specific engine such as an internal combustion engine, so the interior of the electric vehicle is heated by an electric heating device in winter. In addition, in order to improve the charging / discharging performance of the battery during a cold period, preheating is required, so a separate cooling water heating type electric heater is used.

[0005] That is, a technology is adopted in which a heating / cooling system for controlling the temperature of a battery module is operated separately from a heating / cooling system for internal air conditioning of a vehicle to maintain an optimal temperature environment of the battery module. In other words, two independent heating / cooling systems are constructed, one for internal heating / cooling and the other for controlling the temperature of the battery module.

[0006] However, the existing operation method cannot effectively manage energy, resulting in a short driving distance, and long-distance driving cannot be achieved. In addition, when cooling is performed in summer, the driving distance is reduced by 30% or more, and when heating is performed in winter, the driving distance is reduced by 40% or more, so the problem of winter heating becomes serious, and there is no such problem in an internal combustion engine. When a large-capacity PTC is installed to solve the problem of winter heating, there are problems of a reduction in driving distance and an excessive increase in manufacturing cost and weight due to the use of a heat pump.

[0007] Therefore, a technology has been developed to easily install these systems in a vehicle and reduce the weight and manufacturing cost of the vehicle by effectively arranging and configuring these systems as an assembly.

[0008] However, according to the integrated thermal management system of the vehicle of the related art, cooling water heated by a cooling water heater is introduced to a heater core of an interior air conditioner for interior air conditioning, and the cooling water heated by the cooling water heater is also used when raising the temperature of a high-voltage battery.

[0009] However, in this case, the temperature range of the cooling water required for the interior air conditioner is different from the temperature range of the cooling water required when raising the temperature of the high-voltage battery, and thus the performance of the interior air conditioner is limited when raising the temperature of the high-voltage battery.

[0010] The information included in the Background section of the present disclosure is only intended to enhance the understanding of the general background of the present disclosure and is not intended to be taken as an acknowledgement or any form of suggestion that this information forms a prior art that is already known to those skilled in the art. SUMMARY

[0011] Various aspects of the present disclosure are directed to providing a technology capable of appropriately controlling the temperature of cooling water so that both interior heating by an interior air conditioner heating core and raising the temperature of a high-voltage battery satisfy performance requirements.

[0012] According to various aspects of the present disclosure, an integrated thermal management system of a vehicle is provided.

[0016] The controller can increase the ratio of the flow of the cooling water merged from the internal heating line into the battery line by controlling the first valve, thereby increasing a temperature of the cooling water introduced to the high-voltage battery, or can increase the ratio of the flow of the cooling water bypassing the high-voltage battery and flowing into the internal heating line by controlling the first valve, thereby decreasing the temperature of the cooling water introduced to the high-voltage battery.

[0018] The integrated thermal management system can further include a second valve installed at a branching point from the battery line to the bypass line or a connection point of the bypass line and the battery line and regulating a flow of the cooling water; wherein the controller can adjust a ratio of a flow of the cooling water flowing into the first radiator and a flow of the cooling water flowing into the bypass line by controlling the second valve.

[0019] The controller can increase the ratio of the flow of the cooling water flowing into the first radiator by controlling the second valve, thereby decreasing a temperature of the cooling water introduced to the high-voltage battery, or can increase the ratio of the flow of the cooling water flowing into the bypass line by controlling the second valve, thereby decreasing the temperature of the cooling water introduced to the high-voltage battery.

[0020] The integrated thermal management system can further include an electronic device line connected to an electronic device to be configured to perform heat exchange, having a second radiator and having cooling water flowing by a third pump; wherein the electronic device line can be separated from the bypass line and connected to the refrigerant line to be configured to perform heat exchange at the chiller.

[0022] The integrated thermal management system of the vehicle according to the present application has an effect that the performance of the interior air-conditioning heater can be maintained even if the high-voltage battery temperature is raised.

[0023] Further, the integrated thermal management system of the vehicle according to the present application has an effect that the thermal management efficiency is improved by integrating the thermal management of the high-voltage battery, the electronic device, and the interior air-conditioning, which can be maintained in different temperature ranges.

[0037] Figure 1 is a schematic view showing a configuration of an integrated thermal management system of a vehicle according to an example embodiment of the present application.

[0038] Referring to Figure 1 , an integrated thermal management system of a vehicle according to an example embodiment of the present application includes a battery line 100 connected to a high voltage battery B to be configured to perform heat exchange, the battery line 100 having a first radiator R1 and having cooling water flowing through a first pump P1; an interior heating line 200 connected to an interior air conditioning heating core 230, the interior heating line 200 having a cooling water heater 220, having cooling water flowing through a second pump P2, and having a first valve 210 at a downstream side of the heating core 230; a first battery heating line 300 branched from the interior heating line 200 at a downstream side of the heating core 230 and connected to the battery line 100 at an upstream side of the high voltage battery B; a second battery heating line 400 branched from the battery line 100 at a downstream side of the high voltage battery B and connected to the interior heating line 200; and a controller 500 simultaneously operating the first pump P1 and the second pump P2 such that the cooling water in the interior heating line 200 merges with the cooling water in the battery line 100 through the first battery heating line or the second battery heating line and then introduced to the high voltage battery B.

[0039] The cooling water can flow through the battery line 100 by the first pump P1, and the cooling water can flow to the high-pressure battery B to be configured to perform heat exchange. The cooling water in the battery line 100 can be connected to the outside air through the first radiator R1 to be configured to perform heat exchange.

[0040] The internal air-conditioning heating core 230 is installed in the internal heating line 200, and the cooling water flowing by the second pump P2 can circulate in the internal heating line 200. The cooling water heater 220 is installed at the upstream side of the internal air-conditioning heating core 230, and is capable of heating the cooling water.

[0041] The first battery heating line 300 and the second battery heating line 400 can connect the internal heating line 200 and the battery line 100. Specifically, the first battery heating line 300 and the second battery heating line 400 can be branched from the upstream side and the downstream side of the high-pressure battery B, respectively, and then can be connected to the internal heating line 200 at the downstream side of the heating core 230.

[0042] The first battery heating line 300 can be located at the upstream side of the second battery heating line 400, and when the second pump P2 is operated, the cooling water is branched from the internal heating line 200 to the battery line 100 through the first battery heating line 300, and the cooling water that has passed through the high-pressure battery B in the battery line 100 can be merged into the internal heating line 200 through the second battery heating line 400.

[0043] The controller 500 according to an exemplary embodiment of the present application can be implemented by a non-volatile memory configured to store data for controlling the operation of various components of a vehicle or software commands for executing an algorithm, and a processor configured to execute the operation described below using the data stored in the memory. The memory and the processor can be separate chips. Alternatively, the memory and the processor can be integrated in a single chip. The processor can be implemented as one or more processors.

[0044] The controller 500 simultaneously operates the first pump P1 and the second pump P2, whereby the cooling water in the internal heating line 200 and the cooling water in the battery line 100 can be mixed through the first battery heating line 300 and the second battery heating line 400.

[0045] When only the first pump P1 is operated, the cooling water in the battery line 100 can circulate in the battery line 100. Accordingly, the high-pressure battery B can be cooled.

[0046] When only the second pump P2 is operated, the cooling water in the inner heating line 200 can be circulated to be introduced to the high voltage battery B through the first battery heating line 300, and to be introduced back to the inner heating line 200 through the second battery heating line 400. Accordingly, the temperature of the high voltage battery B can be increased. In increasing the temperature of the high voltage battery B, approximately 40 ~ 50°C is preferred.

[0047] In order to heat the interior by the inner air conditioning heating core 230, the temperature of the cooling water in the inner heating line 200 introduced to the heating core 230 can be approximately 70°C, and the temperature of the cooling water having passed through the heating core 230 is approximately 60°C, which is a relatively high temperature for increasing the temperature of the high voltage battery B.

[0048] Accordingly, according to the related art, the temperature of the cooling water in the inner heating line 200 is decreased to maintain the temperature of the cooling water introduced to the high voltage battery B at an appropriate level, but there is a problem in that the inner heating performance is deteriorated.

[0049] According to an exemplary embodiment of the present application, in order to solve this problem, the first pump P1 and the second pump P2 can be both operated so that the cooling water in the battery line 100 and the cooling water in the inner heating line 200 can be introduced to the high voltage battery B after they are mixed.

[0050] The reservoir 900 stores the cooling water in both the battery line 100 and the electronic device line 800. The inside of the reservoir 900 is partitioned from each other so that the cooling water in the battery line 100 and the cooling water in the electronic device line are not mixed with each other.

[0051] Figure 2 、 Figure 3 and Figure 4 are schematic diagrams showing the flow of the cooling water in the integrated thermal management system of the vehicle according to various embodiments of the present application.

[0052] Referring to Figure 2 , the controller 500 can control the rotation speed of the first pump P1 and the rotation speed of the second pump P2 based on the required temperature or the required flow rate of the cooling water introduced to the high voltage battery B.

[0053] The controller 500 can control the rotation speed of the first pump P1 and the rotation speed of the second pump P2 so that the temperature of the cooling water ③ introduced to the high voltage battery B matches the required temperature.

[0054] The temperature Temp3 of the cooling water ③ introduced to the high voltage battery B can be determined as follows based on the outlet temperature Temp1 of the heating core 230, the proportion of the cooling water ① of the inner heating line 200, the temperature Temp2 of the cooling water in the battery line 100 introduced to the upstream side of the battery line 100, and the proportion of the cooling water ② of the battery line 100:

[0055] Temp3 = ① proportion of cooling water x Temp1 + ② proportion of cooling water x Temp2

[0056] As an exemplary embodiment of the present application, the controller 500 can decrease the proportion of the cooling water ① of the internal heating line 200 by increasing the rotation speed of the first pump P1 or decreasing the rotation speed of the second pump P2, thereby decreasing the temperature of the cooling water ③ introduced to the high-voltage battery B.

[0057] Alternatively, the controller 500 can increase the proportion of the cooling water ① of the internal heating line 200 by decreasing the rotation speed of the first pump P1 or increasing the rotation speed of the second pump P2, thereby increasing the temperature of the cooling water ③ introduced to the high-voltage battery B.

[0058] Further, the controller 500 can control the rotation speeds of the first pump P1 and the second pump P2 such that the flow rate of the cooling water ③ introduced to the high-voltage battery B follows a required flow rate. In more detail, the flow rate of the cooling water can be controlled by simultaneously increasing or decreasing the rotation speeds of the first pump P1 and the second pump P2. That is, the rotation speeds of the first pump P1 and the second pump P2 can be increased or decreased with the proportion of the cooling water ① of the internal heating line 200 and the proportion of the cooling water ② of the battery line 100 being fixed.

[0059] As described below, the cooling water ④ in the battery line 100 discharged from the high-voltage battery B can be introduced back to the battery line 100 on the upstream side of the high-voltage battery B after passing through the chiller 700 or the first radiator R1. The temperature Temp4 of the cooling water ④ in the battery line 100 discharged from the high-voltage battery B can be the same as the temperature Temp2 of the cooling water introduced to the battery line 100 on the upstream side of the high-voltage battery B, but can also vary depending on whether heat exchange is performed through the chiller 700 or the proportion of the cooling water flowing into the first radiator R1, as described above.

[0060] Referring to Figure 3 , the system can further include a first valve 210 installed at a point at which the internal heating line 200 branches to the first battery heating line 300 or at a point at which the second battery heating line 400 is connected to the internal heating line 200, and regulating the flow of the cooling water.

[0061] The first valve 210 is a three-way valve installed at a point at which the internal heating line 200 branches or is connected to the internal heating line 200, and can regulate the proportion of the cooling water between the cooling water ① branched from the internal heating line 200 to the first battery heating line 300 and the cooling water ⑤ flowing through the internal heating line 200 bypassing the high-voltage battery B.

[0062] Alternatively, the first valve 210 can be installed at a point at which the battery line 100 is connected to the internal heating line 200 through the second battery heating line 400.

[0063] The controller 500 can adjust the ratio of the flow rate of the cooling water ① flowing from the internal heating line 200 into the battery line 100 to the flow rate of the cooling water ⑤ bypassing the high-voltage battery B and flowing into the internal heating line 200 by controlling the first valve 210.

[0064] More specifically, the controller 500 can increase the ratio of the flow rate of the cooling water ① flowing from the internal heating line 200 into the battery line 100 by controlling the first valve 210, thereby increasing the temperature of the cooling water introduced to the high-voltage battery B.

[0065] Alternatively, the controller 500 can increase the ratio of the flow rate of the cooling water ⑤ bypassing the high-voltage battery B and flowing into the internal heating line 200 by controlling the first valve 210, thereby decreasing the temperature of the cooling water introduced to the high-voltage battery B.

[0066] That is, the controller 500 can adjust the ratio between the cooling water flowing into the high-voltage battery B and the cooling water ⑤ bypassing the high-voltage battery B by controlling the first valve 210, thereby controlling the temperature of the cooling water introduced to the high-voltage battery B and adjusting the amount of heat supplied to the high-voltage battery B from the internal heating line 200.

[0067] Referring again to Figure 1 , the system can further include a refrigerant line 600 having an internal air conditioning cooling core 610 and a compressor 620, and having a water-cooled condenser 640 connected to the internal heating line 200 to be configured to perform heat exchange or an air-cooled condenser 630 exposed to outside air to be configured to perform heat exchange with outside air, a bypass line 110 branched from the battery line 100, bypassing the first radiator R1, and connected to the battery line 100 on the upstream side of the first pump P1, and a chiller 700 to which the bypass line 110 and the refrigerant line 600 are connected to be configured to perform heat exchange.

[0068] The refrigerant line 600 can cool the cooling water in the battery line 100 using the chiller 700 by cooling the internal air conditioning cooling core 610 of the refrigerant line 600. The refrigerant compressed by the compressor 620 in the refrigerant line 600 can be cooled by the air-cooled condenser 630 or the water-cooled condenser 640. The water-cooled condenser 640 is installed on the upstream side of the cooling water heater 220 in the internal heating line 200 and can perform heat exchange with the cooling water in the internal heating line 200.

[0069] The bypass line 110 bypassing the first radiator R1 is connected to the battery line 100, and the cooling water in the battery line 100 can be heat-exchanged with the refrigerant line 600 at the chiller 700 in the bypass line 110.

[0070] The system can further include a second valve 120 installed at a point branching from the battery line 100 to the bypass line 110 or a point at which the bypass line 110 is connected to the battery line 100, and regulating the flow of the cooling water.

[0071] The second valve 120 can be a three-way valve installed at a point branching from the battery line 100 to the bypass line 110 or a point at which the bypass line 110 is connected to the battery line 100, and capable of regulating the ratio between the flow of the cooling water ⑥ flowing into the first radiator R1 and the flow of the cooling water ②-⑥ flowing into the bypass line 110.

[0072] The controller 500 can regulate the ratio between the flow of the cooling water ⑥ flowing into the first radiator R1 and the flow of the cooling water ②-⑥ flowing into the bypass line 110 by controlling the second valve 120.

[0073] As shown in FIG. 5, the controller 500 can control the second valve 120 to block the cooling water flowing into the first radiator R1, and allow only the cooling water flowing into the bypass line 110 to be introduced to the high-voltage battery B. Figure 2

[0074] As another exemplary embodiment of the present application, as shown in FIG. 6, the controller 500 can control the second valve 120 so that the cooling water flows into the first radiator R1. Figure 4

[0075] Specifically, the controller 500 can increase the ratio of the flow of the cooling water ⑥ flowing into the first radiator R1 by controlling the second valve 120, thereby lowering the temperature of the cooling water introduced to the high-voltage battery B, or can increase the ratio of the flow of the cooling water ②-⑥ flowing into the bypass line 110 by controlling the second valve 120, thereby lowering the temperature of the cooling water introduced to the high-voltage battery B.

[0076] The system can further include an electronic device line 800 connected to an electronic device 810, configured to be heat-exchanged, the electronic device line 800 having a second radiator R2, and having cooling water flowing through a third pump P3. The electronic device line 800 can be separated from the bypass line 110 and connected to the refrigerant line 600, configured to be heat-exchanged at the chiller 700.

[0077] ​​The electronic device line 800 can be configured separately from the battery line 100, since the electronic device line 800 is managed in a temperature range different from the high-pressure battery B, and can be heat-exchanged with the refrigerant line 600 at the chiller 700, like the bypass line 110 branched from the battery line 100. Accordingly, the chiller 700 can recover waste heat of cooling water heated by the high-pressure battery B or the electronic device 810 through the refrigerant line 600.

[0078] The chiller 700 and the internal air conditioning cooling core 610 of the refrigerant line 600 can be connected to each other in parallel, a first expansion valve can be installed at an upstream side of the chiller 700, and a second expansion valve 660 can be installed at an upstream side of the internal air conditioning cooling core 610.

[0079] The first expansion valve 650 connected to the refrigerant line 600 is installed at an upstream side of the chiller 700 and can control the flow rate of the refrigerant flowing into the chiller 700, and the second expansion valve 660 is installed at an upstream side of the internal air conditioning cooling core 610 and can control the flow rate of the refrigerant flowing into the internal air conditioning cooling core 610.

[0080] The controller 500 can control the cooling amount of the refrigerant line 600 at the chiller 700 by controlling the turn-on / turn-off of the first expansion valve 650, the turn-on / turn-off of the second expansion valve 660, or the operation of the compressor 620. That is, the controller 500 can control the flow rate of the refrigerant flowing into the chiller 700 by controlling the turn-on / turn-off of the first expansion valve 650, the turn-on / turn-off of the second expansion valve 660, or the operation of the compressor 620, and thus, the controller 500 can adjust the temperature of the cooling water in the battery line 100 by adjusting the cooling amount of the cooling water flowing into the bypass line 110.

[0081] That is, the controller 500 can control the temperature of the cooling water introduced into the high-pressure battery B by controlling the turn-on / turn-off of the first expansion valve 650, the turn-on / turn-off of the second expansion valve 660, or the operation of the compressor 620.
