Description

Technical Field

[0001] This invention relates to the field of battery swapping for energy vehicles, and more particularly to an integrated thermal management system. Background Technology

[0002] With the rapid development of electric vehicles, one of the major challenges facing the industry is how to quickly replenish their energy, making them as convenient as traditional gasoline-powered cars. The emergence of charging and battery swapping stations has successfully solved this problem. These stations replace the batteries in the vehicle that need charging with fully charged batteries from the battery compartment, and then send the replaced batteries back into the compartment for charging. Lithium-ion batteries are the core component of electric vehicles. As users' demands for electric vehicles increase, the requirements for the power performance and fast-charging performance of the battery system are also rising, leading to higher requirements for the design of the battery cooling system.

[0003] Currently, battery swapping stations for new energy vehicles generally employ distributed thermal management systems for battery pack thermal management. This means each charging station is equipped with its own battery thermal management system, which can heat and cool the battery. However, the requirement for the entire battery pack to be simultaneously cooled and heated is not met, resulting in wasted resources. When heating the battery, the thermal management system typically uses PTC (porcelain heating element), which has an energy conversion efficiency of less than 1. This leads to significant energy waste when the swapping station operates in northern winters. Summary of the Invention

[0037] Example 1

[0038] Figure 1 This is a structural framework diagram of an integrated thermal management system provided in Embodiment 1 of the present invention. Figure 1As shown, the integrated thermal management system includes a refrigeration system 100, a chilled water system 200, a hot water system 300, a battery pack pipeline 500, and a hot / cold reversing valve 400.

[0039] The refrigeration system 100 is connected to the cold water system 200 and the hot water system 300. The cold water system 200 and the hot water system 300 are respectively connected to the same hot and cold reversing valve 400. The hot and cold reversing valve 400 is connected to the battery pack pipeline 500. The battery pack pipeline 500 leads into the battery pack 600 to cool or heat the battery pack 600.

[0040] The refrigeration system 100 is used for cooling or heating, and cools or heats the water in the cold water system 200 or the hot water system 300; the hot / cold water reversing valve 400 can switch between the cold water system 200 and the hot water system 300; the battery pack pipeline 500 cools or heats the battery pack 600 by connecting to the cold water system 200 or the hot water system 300; there can be one or more hot / cold water reversing valves 400.

[0041] Specifically, Figure 2 This is a schematic diagram of an integrated thermal management system provided in Embodiment 1 of the present invention.

[0042] like Figure 2 The refrigeration system 100 shown includes a compressor 101, a four-way reversing valve 102, an air-cooled condenser 103, an evaporator 104, a water-cooled condenser 105, a first solenoid valve 108, and a second solenoid valve 109. The four-way reversing valve 102, the first solenoid valve 108, and the second solenoid valve 109 are used to control the refrigeration system 100 to operate in refrigeration mode, heating mode, or heat recovery mode.

[0043] Specifically, compressor 101 discharges high-temperature, high-pressure refrigerant gas. Both air-cooled condenser 103 and water-cooled condenser 105 liquefy the high-temperature, high-pressure first refrigerant gas into refrigerant. Evaporator 104 evaporates the refrigerant into a second refrigerant gas, which returns to compressor 101 to continue the refrigeration process. The four-way reversing valve 102 adjusts the pipe connection direction at its location to switch operating modes. The first solenoid valve 108 and the second solenoid valve 109 control the flow and cutoff of the refrigerant gas discharged from compressor 101. Therefore, by controlling the first solenoid valve 108 and the second solenoid valve 109, the refrigerant gas discharged from compressor 101 can be discharged into different pipes according to the different refrigeration modes. Through the cooperation of the four-way reversing valve 102, the first solenoid valve 108, and the second solenoid valve 109, the refrigeration system 100 can be controlled to operate in refrigeration mode, heating mode, or heat recovery mode.

[0044] The chilled water system 200 includes a first water pump 201 connected to the evaporator 104 and a chilled water pipeline 202;

[0045] The water in the cold water pipe 202 is cooled by the evaporator 104. The refrigerant flowing through the evaporator 104 evaporates into a gaseous state and then lowers its temperature, thereby absorbing heat from the water in the cold water pipe 202 to lower the water temperature to become chilled water.

[0046] The hot water system 300 includes a second water pump 301 connected to the water-cooled condenser 105 and a hot water pipe 302;

[0047] In this process, the water in the hot water pipe 302 is heated by the water-cooled condenser 105. The refrigerant flowing through the water-cooled condenser 105 is compressed by the compressor into a high-temperature and high-pressure refrigerant, which then releases heat to the water in the hot water pipe 302, thereby raising the water temperature in the hot water pipe 302 to become heated water.

[0048] The hot / cold reversing valve 400 is used to switch the connection of the cold water system 200 or the hot water system 300 to the battery pack pipeline 500.

[0049] Different hot and cold reversing valves switch the connection of the cold water system 200 or the hot water system 300 to the battery pack pipeline corresponding to the hot and cold reversing valve.

[0050] The battery pack piping 500 is connected to the hot / cold reversing valve 400 and passes through the battery pack 600 to cool or heat the battery pack 13.

[0051] Specifically, the cold water system 200 and the hot water system 300 are connected to multiple hot and cold reversing valves 400. Each hot and cold reversing valve 400 is connected to a corresponding battery pack pipeline 500 for simultaneously cooling and / or heating the corresponding battery pack 600.

[0052] The refrigeration system 100 also includes a first throttling mechanism 106 and a second throttling mechanism 107, which are used to control the flow rate of the refrigerant discharged from the air-cooled condenser 103.

Figure 3 for Figure 2 Schematic diagram of the 400 intercooler / heater reversing valve. Figure 3 As shown, the hot / cold reversing valve 400 includes a valve body 401 and a valve core 402. The valve core 401 switches between the cold water system 200 and the hot water system 300 via rotation and is connected to the battery pack pipeline 500.

[0054] Specifically, the valve body 402 includes a cold water inlet 4011, a hot water inlet 4012, a cold water outlet 4016, a hot water outlet 4013, a first battery inlet 4014, and a second battery inlet 4015; wherein the cold water inlet 4011, the hot water inlet 4012, the cold water outlet 4016, the hot water outlet 4013, the first battery inlet 4014, and the second battery inlet 4015 are evenly distributed on the outside of the valve body 402.

[0055] The valve core 402 is located inside the valve body 401. The valve core 402 has a valve core pipeline 4021 inside. By rotating the valve core 402, the valve core pipeline can connect to different water inlets and different battery water inlets on the valve body 402, and at the same time divide the valve body 401 into two unconnected water channels.

[0056] Specifically, such as Figure 3 As shown, valve core 402 is switched between cold water inlet 4011 and first battery inlet 4014. At this time, battery pack pipeline 500 is connected to cold water system 200 through hot / cold reversing valve 400. Further, cold water enters from cold water inlet 4011, enters battery pack pipeline 500 from first battery inlet 4014, enters battery pack 600, cools battery pack 600, enters second battery inlet 4015 from battery pack pipeline 500, enters valve body 401, and then enters cold water system 200 from cold water outlet 4016.

[0057] Optionally, valve core 402 can also be redirected to hot water inlet 4012 and second battery inlet 4015. In this case, battery pack pipeline 500 is connected to hot water system 300 through hot / cold reversing valve 400.

The air-cooled condenser 106 is used to liquefy the first refrigerant gas discharged from compressor 101 into the first refrigerant liquid; the inlet of evaporator 104 is connected to the outlet of air-cooled condenser 103 through the first throttling mechanism 106 and the second throttling mechanism 107. The evaporator 104 is used to evaporate the first refrigerant liquid into the second refrigerant gas; the inlet of compressor 101 is connected to the outlet of evaporator 104 through the four-way reversing valve 102. The evaporator 104 is used to discharge the second refrigerant gas into compressor 101.

[0061] The evaporator 104 cools the water in the cold water pipe 202. Furthermore, the hot / cold reversing valve 400 connects to the cold water system 200, directing cold water into the battery pack pipe 500 to cool the battery pack 600, thus achieving battery cooling.

[0064] Specifically, at this time, the refrigeration system works as follows: the exhaust port of compressor 101 is connected to the inlet of water-cooled condenser 105 through the first solenoid valve 108. Water-cooled condenser 105 is used to liquefy the third refrigerant gas discharged from compressor 101 into the second refrigerant. The inlet of air-cooled condenser 103 is connected to the outlet of water-cooled condenser 105 through the first throttling mechanism 106. Air-cooled condenser 103 is used as an evaporator at this time to evaporate the second refrigerant into the fourth refrigerant gas. The air inlet of compressor 101 is connected to the outlet of air-cooled condenser 103 through the four-way reversing valve 102 to discharge the fourth refrigerant gas into compressor 101.

[0065] The water-cooled condenser 105 heats the water in the hot water pipe 302. Furthermore, the hot / cold reversing valve 400 connects to the hot water system 300, directing hot water into the battery pack pipe 500 to heat the battery pack 600, thus heating the battery.

[0066] Figure 6 This is a schematic diagram of the working structure of an integrated thermal management system in heat recovery mode according to Embodiment 1 of the present invention.

Furthermore, different hot / cold reversing valves 400 are connected to the cold water system 200 or the hot water system 300, supplying cold or hot water to different battery pack pipes 500 to cool or heat different battery packs 600, thus achieving simultaneous cooling or heating of different battery packs.
