Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and in particular to a cooling system for automobiles.

[0002] The power battery temperature control device being tested. Background Technology

[0003] For new energy vehicles, the performance test of the vehicle's cooling system mainly focuses on its temperature control effect on the power battery. In existing technologies, the conventional practice for testing the temperature control effect of the vehicle's cooling system on the power battery is to lower the temperature of the ring mold chamber to the target temperature, and then leave the vehicle in the ring mold chamber for a long period of time (more than 15 hours) until the power battery temperature reaches the specified temperature before starting the test.

[0004] If repeated testing or testing under different operating conditions is required, the immersion test must be repeated. This method results in a longer testing cycle due to the longer immersion time, which not only consumes testing resources and increases testing costs, but also greatly reduces production efficiency.

[0014] Furthermore, the testing device also includes a temperature acquisition component disposed on the power battery, the temperature acquisition component being used to acquire the temperature of the power battery.

[0015] Furthermore, the temperature acquisition component includes a temperature sensor mounted on the power battery and a digital display mounted outside the environmental chamber, wherein the temperature sensor is electrically connected to the digital display.

[0016] The power battery temperature control device for testing automotive cooling systems proposed in this utility model has the following beneficial effects:

[0017] (1) This temperature control device provides temperature control medium through temperature control mechanism, and the connecting pipeline delivers temperature control medium to power battery to cool or heat up power battery so that it can quickly reach the temperature required for automotive cooling system testing, thereby greatly reducing the immersion time of automotive cooling system testing, shortening the testing cycle, and thus reducing production costs and improving production efficiency.

[0018] (2) This temperature control device uses a first interceptor to cut off the liquid inlet pipe of the power battery, a second interceptor to cut off the liquid outlet pipe of the power battery, a third interceptor to cut off the liquid inlet pipe of the vehicle cooling system, and a fourth interceptor to cut off the liquid outlet pipe of the vehicle cooling system, thereby preventing the leakage of coolant in the liquid inlet and outlet pipes of the vehicle cooling system, as well as the liquid inlet and outlet pipes of the power battery, and ensuring the temperature control effect of the subsequent vehicle cooling system on the power battery;

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Please see Figures 1-3This utility model discloses a temperature control device for a power battery 102 used in testing an automotive cooling system 101. The device includes an environmental chamber 1, a temperature control mechanism 2, and a connecting pipe 3. The environmental chamber 1 can accommodate the entire vehicle 10, and the temperature control mechanism 2 is disposed within it. When the vehicle 10 is driven into the environmental chamber 1, the temperature control mechanism 2 is connected to the power battery 102 of the vehicle 10 via the connecting pipe 3. The temperature control mechanism 2 provides a temperature control medium, and the connecting pipe 3 delivers the temperature control medium to the power battery 102, thereby cooling or heating the power battery 102.

[0030] For new energy vehicles, the performance test of the vehicle cooling system 101 mainly focuses on its temperature control effect on the power battery 102. In existing technology, the conventional practice for testing the temperature control effect of the vehicle cooling system 101 on the power battery 102 is to lower the ambient temperature to the target temperature, then allow the vehicle to remain stationary in the ambient temperature chamber for an extended period (more than 15 hours) until the power battery 102 reaches the specified temperature before starting the test. If repeated testing or testing under different operating conditions is required, the vehicle immersion test must be repeated.

[0031] This method, due to the long immersion time, results in a prolonged testing cycle, consuming testing resources, increasing testing costs, and significantly reducing production efficiency. In this application, however, a temperature control medium is provided by a temperature control mechanism 2, and the medium is delivered to the power battery 102 via a connecting pipe 3. This cools or heats the power battery 102, quickly bringing it to the temperature required for testing the automotive cooling system 101. This significantly reduces the immersion time for testing the automotive cooling system 101, shortens the testing cycle, and consequently reduces production costs and improves production efficiency.

[0032] In practical use, the vehicle cooling system 101 is provided with a vehicle cooling system inlet pipe 1011 and a vehicle cooling system outlet pipe 1012, and the power battery 102 is provided with a power battery inlet pipe 1021 and a power battery outlet pipe 1022. The vehicle cooling system outlet pipe 1012 is connected to the power battery inlet pipe 1021, and the vehicle cooling system inlet pipe 1011 is connected to the power battery outlet pipe 1022, so that the coolant in the vehicle cooling system 101 circulates between the vehicle cooling system 101 and the power battery 102, and then heat is exchanged between the coolant and the power battery 102 to achieve temperature control of the power battery 102.

[0033] As mentioned in the preceding embodiments, the connecting pipe 3 connects the temperature control mechanism 2 to the power battery 102. Specifically, it connects the temperature control mechanism 2 to the power battery inlet pipe 1021 and the power battery outlet pipe 1022. Therefore, in this application, before testing the temperature control effect of the vehicle cooling system 101 on the power battery 102, the connections between the vehicle cooling system outlet pipe 1012 and the power battery inlet pipe 1021, and between the vehicle cooling system inlet pipe 1011 and the power battery outlet pipe 1022, must be disconnected.

[0034] Then, the temperature control mechanism 2 is connected to the power battery inlet pipe 1021 and the power battery outlet pipe 1022 through the connecting pipe 3, so that the temperature control medium provided by the temperature control mechanism 2 circulates between the temperature control mechanism 2 and the power battery inlet pipe 1021 and the power battery outlet pipe 1022, thereby exchanging heat with the power battery 102 through the temperature control medium, so as to achieve cooling or heating of the power battery 102.

[0035] It is foreseeable that the temperature control medium provided by the temperature control mechanism 2 of this application is the same as the coolant circulating between the vehicle cooling system 101 and the power battery 102. The difference is that the temperature control mechanism 2 can control the output coolant temperature, thereby exchanging heat with the power battery 102 through the coolant circulating between the temperature control mechanism 2 and the power battery 102, so as to achieve cooling or heating of the power battery 102.

[0036] Disconnecting the connection between the vehicle cooling system outlet pipe 1012 and the power battery inlet pipe 1021, as well as between the vehicle cooling system inlet pipe 1011 and the power battery outlet pipe 1022, will cause coolant leakage in the vehicle cooling system inlet pipe 1011 and outlet pipe 1012, as well as between the power battery inlet pipe 1021 and outlet pipe 1022. This will affect the subsequent testing of the temperature control effect of the vehicle cooling system 101 on the power battery 102, and will also affect the temperature control effect of the vehicle cooling system 101 on the power battery 102 during normal vehicle use.

[0037] Therefore, in this application, the temperature control device also includes a first interceptor 4, a second interceptor 5, a third interceptor 6, and a fourth interceptor 7. The first interceptor 4 is disposed on the power battery inlet pipe 1021, the second interceptor 5 is disposed on the power battery outlet pipe 1022, the third interceptor 6 is disposed on the vehicle cooling system inlet pipe 1011, and the fourth interceptor 7 is disposed on the vehicle cooling system outlet pipe 1012.

[0038] Before disconnecting the connection between the vehicle cooling system outlet pipe 1012 and the power battery inlet pipe 1021, and between the vehicle cooling system inlet pipe 1011 and the power battery outlet pipe 1022, the first interceptor 4 intercepts the power battery inlet pipe 1021, the second interceptor 5 intercepts the power battery outlet pipe 1022, the third interceptor 6 intercepts the vehicle cooling system inlet pipe 1011, and the fourth interceptor 7 intercepts the vehicle cooling system outlet pipe 1012. This prevents coolant leakage from the vehicle cooling system inlet pipe 1011 and outlet pipe 1012, as well as the power battery inlet pipe 1021 and outlet pipe 1022, ensuring the temperature control effect of the vehicle cooling system 101 on the power battery 102.

[0039] Specifically, in this embodiment, the first flow cut-off member 4, the second flow cut-off member 5, the third flow cut-off member 6, and the fourth flow cut-off member 7 are all flow cut-off clamps. Before disconnecting the connection between the vehicle cooling system outlet pipe 1012 and the power battery inlet pipe 1021, two flow cut-off clamps are respectively clamped at the ends of the power battery inlet pipe 1021 and the vehicle cooling system outlet pipe 1012 to prevent coolant leakage from the power battery inlet pipe 1021 and the vehicle cooling system outlet pipe 1012.

[0040] Before disconnecting the connection between the vehicle cooling system inlet pipe 1011 and the power battery outlet pipe 1022, clamp two additional flow cut-off clamps at the ends of the power battery outlet pipe 1022 and the vehicle cooling system inlet pipe 1011 to prevent coolant leakage from the power battery outlet pipe 1022 and the vehicle cooling system inlet pipe 1011, thereby ensuring the temperature control effect of the vehicle cooling system 101 on the power battery 102.

[0041] After connecting the temperature control mechanism 2 to the power battery inlet pipe 1021 and the power battery outlet pipe 1022 via the connecting pipe 3, the two flow-cutting clamps on the power battery inlet pipe 1021 and the power battery outlet pipe 1022 are removed respectively. This allows the temperature control medium provided by the temperature control mechanism 2 to be transported to the power battery inlet pipe 1021 through the connecting pipe 3, and then flow back to the temperature control mechanism 2 through the power battery outlet pipe 1022. During this process, the temperature control medium exchanges heat with the power battery 102, thereby cooling or heating the power battery 102.

[0042] In this embodiment, the connecting pipe 3 includes an inlet three-way regulating valve 31 and an outlet three-way regulating valve 32. After the connection between the vehicle cooling system outlet pipe 1012 and the power battery inlet pipe 1021 is disconnected, the inlet three-way regulating valve 31 is installed on the power battery inlet pipe 1021, so that the first end of the inlet three-way regulating valve 31 is connected to the power battery inlet pipe 1021, the second end is connected to the temperature control mechanism 2, and the third end is connected to the vehicle cooling system outlet pipe 1012.

[0043] After disconnecting the connection between the inlet pipe 1011 of the vehicle cooling system and the outlet pipe 1022 of the power battery, install the outlet three-way regulating valve 32 on the outlet pipe 1022 of the power battery, so that the first end of the outlet three-way regulating valve 32 is connected to the outlet pipe 1022 of the power battery, the second end is connected to the temperature control mechanism 2, and the third end is connected to the inlet pipe 1011 of the vehicle cooling system.

[0044] Therefore, by controlling the temperature of the power battery 102 through the temperature control mechanism 2, when the power battery 102 quickly reaches the specified temperature, the first and second ends of the inlet three-way regulating valve 31 and the first and second ends of the outlet three-way regulating valve 32 are opened, while the third end of the inlet three-way regulating valve 31 and the third end of the outlet three-way regulating valve 32 are closed, allowing the temperature control medium provided by the temperature control mechanism 2 to circulate between the power battery 102 and the temperature control mechanism 2. During this process, the temperature control medium exchanges heat with the power battery 102, achieving cooling or heating of the power battery 102.

[0045] After the power battery 102 reaches the specified temperature, the first and second ends of the inlet three-way regulating valve 31 and the first and second ends of the outlet three-way regulating valve 32 are closed, while the third end of the inlet three-way regulating valve 31 and the third end of the outlet three-way regulating valve 32 are opened. The two flow cut-off clamps on the inlet pipe 1011 and the outlet pipe 1012 of the vehicle cooling system are removed respectively, so that the temperature control effect of the vehicle cooling system 101 on the power battery 102 can be tested, further shortening the test time, thereby reducing production costs and improving production efficiency.

[0046] Furthermore, in this embodiment, the connecting pipe 3 also includes a first inlet pipe 33 and a first return pipe 34. The first inlet pipe 33 connects the second end of the inlet three-way regulating valve 31 to the temperature control mechanism 2, and the first return pipe 34 connects the second end of the outlet three-way regulating valve 32 to the temperature control mechanism 2. In this application, by connecting the second end of the inlet three-way regulating valve 31 to the temperature control mechanism 2 through the first inlet pipe 33, when the first and second ends of the inlet three-way regulating valve 31 are open, the temperature control medium provided by the temperature control mechanism 2 can enter the power battery inlet pipe 1021 through the first inlet pipe 33, the second end of the inlet three-way regulating valve 31, and the first end.

[0047] The second end of the outlet three-way regulating valve 32 is connected to the temperature control mechanism 2 via the first return pipe 34. When the first and second ends of the outlet three-way regulating valve 32 are open, the temperature control medium entering the water inlet pipe of the power battery 102 can flow back to the temperature control mechanism 2 through the first and second ends of the outlet three-way regulating valve 32 and the first return pipe 34. During this process, the temperature control medium exchanges heat with the power battery 102, thereby cooling or heating the power battery 102.

[0048] In this embodiment, the connecting pipe 3 also includes a first quick connector 35 and a second quick connector 36. When the first infusion pipe 33 connects the second end of the water inlet three-way regulating valve 31 to the temperature control mechanism 2, the first infusion pipe 33 is connected to the temperature control mechanism 2 through the first quick connector 35.

[0049] When the first return pipe 34 connects the second end of the outlet three-way regulating valve 32 to the temperature control mechanism 2, the first return pipe 34 is connected to the temperature control mechanism 2 through the second quick connector 36. This makes the connection between the first delivery pipe 33 and the temperature control mechanism 2, as well as the connection between the first return pipe 34 and the temperature control mechanism 2, simpler, more convenient, and easier to implement, further shortening the testing time, thereby reducing production costs and improving production efficiency.

[0050] In this embodiment, the temperature control mechanism 2 includes a housing 21, a circulation pipeline, a cooler 24, a heater 25, and a delivery pump 26. The circulation pipeline is disposed in the housing 21, and the inlet and outlet ends of the circulation pipeline extend outside the housing 21. A first quick connector 35 connects the first delivery pipe 33 to the outlet end of the circulation pipeline, and a second quick connector 36 connects the first return pipe 34 to the return end of the circulation pipeline. The cooler 24, the heater 25, and the delivery pump 26 are disposed on the circulation pipeline.

[0051] When it is necessary to cool down the power battery 102, the cooler 24 and the delivery pump 26 are started, so that the delivery pump 26 delivers the coolant cooled by the cooler 24 through the outlet end of the circulation pipeline to the first delivery pipe 33, and then through the first delivery pipe 33 and the inlet three-way regulating valve 31 into the power battery inlet pipe 1021. Then, it flows back to the circulation pipeline through the power battery outlet pipe 1022, the outlet three-way regulating valve 32 and the first return pipe 34. During this process, the cooled coolant exchanges heat with the power battery 102, thereby achieving the cooling of the power battery 102.

[0052] When it is necessary to heat up the power battery 102, the heater 25 and the delivery pump 26 are started, so that the delivery pump 26 delivers the coolant heated by the heater 25 through the outlet end of the circulation pipeline to the first delivery pipe 33, and then through the first delivery pipe 33 and the inlet three-way regulating valve 31 into the power battery inlet pipe 1021. Then, it flows back to the circulation pipeline through the power battery outlet pipe 1022, the outlet three-way regulating valve 32 and the first return pipe 34. During this process, the heated coolant exchanges heat with the power battery 102, thereby achieving the heating of the power battery 102.

[0053] Furthermore, in this embodiment, the temperature control mechanism 2 also includes a liquid storage tank 27, which is disposed in the housing 21 and used to store the temperature control medium. The circulation pipeline includes a second inlet pipe 22 and a second return pipe 23. One end of the second inlet pipe 22 is connected to the liquid storage tank 27 and the other end extends to the outside of the housing 21. One end of the second return pipe 23 is connected to the liquid storage tank 27 and the other end extends to the outside of the housing 21. That is, the outlet end of the circulation pipeline is the end of the second inlet pipe 22 extending to the outside of the housing 21, and the inlet end of the circulation pipeline is the end of the second return pipe 23 extending to the outside of the housing 21.

[0054] In this application, the cooler 24, heater 25, and delivery pump 26 are all mounted on the second liquid delivery pipe 22. The cooler 24 and heater 25 are connected in parallel on the second liquid delivery pipe 22, while the delivery pump 26 is connected in series with the cooler 24 and heater 25 on the second liquid delivery pipe 22. When the cooler 24 and delivery pump 26 are started, the delivery pump 26 delivers the coolant in the storage tank 27 to the first liquid delivery pipe 33 through the second liquid delivery pipe 22. During this process, the coolant flowing through the branch where the cooler 24 is located is cooled down by the cooler 24, thereby cooling the power battery 102 as it flows through it. Finally, the coolant flows back to the storage tank 27 through the second return pipe 23.

[0055] When the heater 25 and the delivery pump 26 are started, the delivery pump 26 delivers the coolant in the storage tank 27 to the first delivery pipe 33 through the second delivery pipe 22. During this process, the coolant flowing through the branch where the heater 25 is located is heated by the heater 25, so that when the coolant flows through the power battery 102, it heats up the power battery 102. Finally, it flows back to the storage tank 27 through the second return pipe 23.

[0056] As mentioned in the previous embodiments, before testing the temperature control effect of the vehicle cooling system 101 on the power battery 102, the temperature of the power battery 102 needs to reach a specified temperature. Therefore, in this embodiment, the temperature control device also includes a temperature acquisition component, which is disposed on the power battery 102 and used to acquire the temperature of the power battery 102.

[0057] The temperature information of the power battery 102 collected by the temperature acquisition component is transmitted to the control system, so that the control system controls the power of the cooler 24 and heater 25 in the temperature control mechanism 2, thereby controlling the temperature of the coolant delivered by the temperature control mechanism 2. The coolant delivered by the temperature control mechanism 2 then exchanges heat with the power battery 102, causing the temperature of the power battery 102 to decrease or increase until the temperature of the power battery 102 collected by the temperature acquisition component reaches the specified temperature.

[0058] Specifically, in this embodiment, the temperature acquisition component includes a temperature sensor 8 and a digital display 9. The temperature sensor 8 is mounted on the power battery 102 and is used to detect the temperature of the power battery 102. The digital display 9 is located outside the environmental chamber 1, and the temperature sensor 8 is electrically connected to the digital display 9, enabling the digital display 9 to display the temperature of the power battery 102 detected by the temperature sensor 8. This facilitates the temperature control device in controlling the temperature of the power battery 102, further shortens the testing time, and thus reduces production costs and improves production efficiency.
