[0062] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0063] The present application discloses a thermal management system, which is applied to a hydrogen production and energy storage system 100 . The hydrogen production and energy storage system 100 includes a hydrogen production device 110 and an electrochemical energy storage device 120 .

[0064] Reference below Figure 1-Figure 3 A thermal management system according to an embodiment of the present application is described.

[0065] In some embodiments, Figure 1-Figure 3 As shown, the thermal management system includes: a first heat exchange circulation loop 131 , a second heat exchange circulation loop 132 , a first temperature sensor 133A, a second temperature sensor 133B and a heat exchanger 135 .

[0066] The first heat exchange circulation loop 131 is connected to the heat dissipation part of the hydrogen production equipment 110; the second heat exchange circulation loop 132 is connected to the heat dissipation part of the electrochemical energy storage device 120; the first temperature sensor 133A is used to detect the temperature of the cooling medium in the first heat exchange circulation loop 131; the second temperature sensor 133B is used to detect the temperature of the cooling medium in the second heat exchange circulation loop 132; the first path of the heat exchanger 135 is connected to the first heat exchange circulation loop 131, and the second path of the heat exchanger 135 is connected to the second circulation loop, and at least one of the first heat exchange circulation loop 131 and the second heat exchange circulation loop 132 can be selectively connected to the heat exchanger 135.

[0067] The cooling medium in the first heat exchange circulation loop 131 may include, but is not limited to, coolant, refrigerant or air, etc., which is not limited here.

[0068] For example, in some embodiments, the cooling medium in the first heat exchange circulation loop 131 is coolant.

[0069] The cooling medium in the second heat exchange circulation loop 132 may include, but is not limited to, coolant, refrigerant or air, etc., which is not limited here.

[0070] For example, in some embodiments, the cooling medium in the second heat exchange circulation loop 132 is a refrigerant.

[0071] In some embodiments, Figure 1As shown, the first heat exchange circulation loop 131 can be selectively connected to the heat exchanger 135 , and the second circulation loop is connected to the heat exchanger 135 .

[0072] In other embodiments, Figure 2 As shown, the first heat exchange circulation loop 131 is connected to the heat exchanger 135 , and the second heat exchange circulation loop 132 can be selectively connected to the heat exchanger 135 .

[0073] In some other embodiments, the first heat exchange circulation loop 131 and the second heat exchange circulation loop 132 may be selectively connected to the heat exchanger 135 .

[0074] The first temperature sensor 133A may be disposed in the first heat exchange circulation loop 131, the hydrogen production equipment 110 or other components, which is not limited here.

[0075] For example, in some embodiments, Figure 1-Figure 3 As shown, the first temperature sensor 133A is disposed in the first heat exchange circulation loop 131 .

[0076] The second temperature sensor 133B may be disposed in the second heat exchange circulation loop 132 , the electrochemical energy storage device 120 , or other components, which is not limited here.

[0077] For example, in some embodiments, Figure 1-Figure 3 As shown, the second temperature sensor 133B is disposed in the second heat exchange circulation loop 132 .

[0078] In actual implementation, Figure 1-Figure 3As shown, when the detection value of the first temperature sensor 133A is too high and the detection value of the second temperature sensor 133B is too low, the operating temperature of the hydrogen production equipment 110 is too high and needs to be dissipated to maintain safe operation, while the operating temperature of the electrochemical energy storage device 120 is too low and needs to be heated to maintain normal operation, and the heat exchanger 135 is connected to the first heat exchange circulation loop 131 and the second heat exchange circulation loop 132. In other words, the cooling medium in the first heat exchange circulation loop 131 can exchange heat with the cooling medium in the second heat exchange circulation loop 132 through the heat exchanger 135, thereby realizing indirect heating of the electrochemical energy storage device 120 by the hydrogen production equipment 110; When the detection value of the first temperature sensor 133A is too low and the detection value of the second temperature sensor 133B is too high, the operating temperature of the hydrogen production equipment 110 is too low and needs to be heated to maintain normal and safe operation, while the operating temperature of the electrochemical energy storage device 120 is too high and needs to be dissipated to maintain safe operation. The heat exchanger 135 is connected to the first heat exchange circulation loop 131 and the second heat exchange circulation loop 132. In other words, the cooling medium in the first heat exchange circulation loop 131 can exchange heat with the cooling medium in the second heat exchange circulation loop 132 through the heat exchanger 135, thereby realizing indirect heating of the hydrogen production equipment 110 by the electrochemical energy storage device 120.

[0079] The thermal management system provided in the embodiment of the present application realizes bidirectional heat exchange between the hydrogen production equipment 110 and the electrochemical energy storage equipment 120 through the arrangement of the above-mentioned heat exchanger 135 and the design that at least one of the first heat exchange circulation loop 131 and the second heat exchange circulation loop 132 can be selectively connected to the heat exchanger 135. When there is surplus heat in the hydrogen production equipment 110 and the electrochemical energy storage equipment 120, they can be used by each other, thereby improving energy utilization and further improving the energy efficiency of the thermal management system. At the same time, the hydrogen production equipment 110 and the electrochemical energy storage equipment 120 can be preheated with each other, which helps to quickly respond and start the hydrogen production equipment 110 and the electrochemical energy storage equipment 120, thereby optimizing the performance of the entire hydrogen production and energy storage system 100.

[0080] In some embodiments, Figure 1-Figure 3 As shown, the thermal management system may further include: a first branch 137 , a first valve 101 , a second valve 102 and a controller 134 .

[0081] The first valve 101 can be arranged in the first branch 137; the second valve 102 can be connected in series with one of the branches of the heat exchanger 135, and one of the branches of the heat exchanger 135 and the second valve 102 can be connected in parallel with the first branch 137; the controller 134 can be electrically connected to the first temperature sensor 133A, the second temperature sensor 133B, the first valve 101 and the second valve 102, and the controller 134 can be used to control the first valve 101 and the second valve 102 based on the detection values ​​of the first temperature sensor 133A and the second temperature sensor 133B.

[0082] In actual implementation, Figure 1-Figure 3 As shown, the first temperature sensor 133A and the second temperature sensor 133B can feed back their respective detection values ​​to the controller 134, and the controller 134 can control the opening and closing states of the first valve 101 and the second valve 102 based on the detection values ​​fed back by the first temperature sensor 133A and the second temperature sensor 133B. Specifically, when the first valve 101 is opened, the cooling medium can flow through the first branch 137, and when the first valve 101 is closed, the cooling medium cannot flow through the first branch 137; when the second valve 102 is opened, the cooling medium can flow through the heat exchanger 135, and when the second valve 102 is closed, the cooling medium cannot flow through the heat exchanger 135.

[0083] It should be noted that if the heat exchange between the hydrogen production device 110 and the electrochemical energy storage device 120 needs to be controlled more accurately, the controller 134 can control the heat exchange per unit time by controlling the opening of the first valve 101 and the second valve 102 .

[0084] The thermal management system provided in the embodiment of the present application, through the settings of the above-mentioned first branch 137, the first valve 101, the second valve 102 and the controller 134, realizes that the thermal management system adjusts the first valve 101 and the second valve 102 according to the operating temperature of the hydrogen production equipment 110 and the energy storage equipment to promote heat exchange between the hydrogen production equipment 110 and the energy storage equipment, and can fully utilize the preheating of the hydrogen production equipment 110 and the energy storage equipment, effectively improve the energy utilization rate, and at the same time, the controller 134 can respond quickly and issue instructions after obtaining data, thereby improving the accuracy of thermal control and reducing heat loss.

[0085] In some embodiments, Figure 2 As shown, the first heat exchange circulation loop 131 can be selectively connected to the heat exchanger 135, the second heat exchange circulation loop 132 can be connected to the heat exchanger 135, the second valve 102 can be connected between the first path of the heat exchanger 135 and the hydrogen production equipment 110, and the first branch 137 can be connected in parallel with the first path of the heat exchanger 135 and the second valve 102.

[0086] In this embodiment, if Figure 2As shown, the first temperature sensor 133A can be arranged between the outlet of the hydrogen production equipment 110 and the inlet of the first path of the heat exchanger 135, and the second temperature sensor 133B can be arranged between the outlet of the electrochemical energy storage device 120 and the inlet of the second path of the heat exchanger 135. When the first valve 101 is opened, the first heat exchange circulation loop 131 can be connected to the first branch 137, and when the first valve 101 is closed, the first heat exchange circulation loop 131 is not connected to the first branch 137; when the second valve 102 is opened, the first heat exchange circulation loop 131 can be connected to the first path of the heat exchanger 135, and when the second valve 102 is closed, the first heat exchange circulation loop 131 is not connected to the first path of the heat exchanger 135.

[0087] The thermal management system provided in the embodiment of the present application is designed that the first heat exchange circulation loop 131 can be selectively connected to the heat exchanger 135 and the second circulation loop is connected to the heat exchanger 135, so that the first branch 137, the first valve 101 and the second valve 102 are all arranged at the location of the first heat exchange circulation loop 131, thereby minimizing the number of valves and pipelines used, improving space utilization and saving manufacturing costs.

[0088] In some embodiments, Figure 1 and Figure 3 As shown, the first heat exchange circulation loop 131 can be connected to the heat exchanger 135, the second heat exchange circulation loop 132 can be selectively connected to the heat exchanger 135, the second valve 102 can be connected between the second path of the heat exchanger 135 and the electrochemical energy storage device 120, and the first branch 137 can be connected in parallel with the second path of the heat exchanger 135 and the second valve 102.

[0089] In this embodiment, if Figure 2 As shown, the first temperature sensor 133A can be arranged between the outlet of the hydrogen production equipment 110 and the inlet of the first path of the heat exchanger 135, and the second temperature sensor 133B can be arranged between the outlet of the electrochemical energy storage device 120 and the inlet of the second path of the heat exchanger 135. When the first valve 101 is opened, the second heat exchange circulation loop 132 can be connected to the first branch 137, and when the first valve 101 is closed, the second heat exchange circulation loop 132 is not connected to the first branch 137; when the second valve 102 is opened, the second heat exchange circulation loop 132 can be connected to the second path of the heat exchanger 135, and when the second valve 102 is closed, the second heat exchange circulation loop 132 is not connected to the second path of the heat exchanger 135.

[0090] The thermal management system provided in the embodiment of the present application is designed that the first heat exchange circulation loop 131 is connected to the heat exchanger 135 and the second heat exchange circulation loop 132 can be selectively connected to the heat exchanger 135, so that the first branch 137, the first valve 101 and the second valve 102 are all arranged at the location of the second heat exchange circulation loop 132, thereby minimizing the number of valves and pipelines used, improving space utilization and saving manufacturing costs.

[0091] In some embodiments, the controller 134 may include: a first comparator and a first processor.

[0092] The first comparator can be used to compare the detection value of the first temperature sensor 133A with the first target threshold, and can be used to compare the detection value of the second temperature sensor 133B with the second target threshold; the first processor can be electrically connected to the first comparator, and the first processor can be used to output a control instruction based on the comparison result. When the comparison result is that the detection value of the first temperature sensor 133A is less than the first target threshold and the detection value of the second temperature sensor 133B is greater than the second target threshold, the control instruction can be used to control the first valve 101 to close and control the second valve 102 to open.

[0093] The first target threshold may be a lower limit value for normal operation of the hydrogen production device 110 , and the second target threshold may be an upper limit value for normal operation of the electrochemical energy storage device 120 , and the second target threshold must be greater than the first target threshold value.

[0094] In actual implementation, Figure 1-Figure 3 As shown, the first temperature sensor 133A and the second temperature sensor 133B can feed back the detection values ​​to the first comparator, and the first comparator can compare the detection value of the first temperature sensor 133A with the first target threshold and compare the detection value of the second temperature sensor 133B with the second target threshold, so as to obtain a comparison result. The first comparator can feed back the comparison result to the first processor. When the comparison result is that the detection value of the first temperature sensor 133A is less than the first target threshold and the detection value of the second temperature sensor 133B is greater than the second target threshold, in response to the comparison result, the controller 134 can output a control instruction, and the control instruction can control the first valve 101 to close, and control the second valve 102 to open.

[0095] It should be noted that, under normal circumstances, the first valve 101 is in an open state, and the second valve 102 is in a closed state.

[0096] The thermal management system provided in the embodiment of the present application realizes data processing of the detection values ​​of the first temperature sensor 133A and the second temperature sensor 133B, and output of instructions for the first valve 101 and the second valve 102 through the settings of the above-mentioned first comparator and the first processor, thereby providing hardware support for numerical comparison. When the hydrogen production equipment 110 is overcooled and the electrochemical energy storage equipment 120 is overheated, the electrochemical energy storage equipment 120 is prompted to indirectly heat the hydrogen production equipment 110, thereby improving the control accuracy of the joint thermal management between the hydrogen production equipment 110 and the electrochemical energy storage equipment 120.

[0097] In some embodiments, the controller 134 may include: a second comparator and a second processor.

[0098] The second comparator can be used to compare the detection value of the first temperature sensor 133A with the third target threshold, and can be used to compare the detection value of the second temperature sensor 133B with the fourth target threshold; the second processor can be electrically connected to the second comparator, and the second processor can be used to output a control instruction based on the comparison result. When the comparison result is that the detection value of the first temperature sensor 133A is greater than the third target threshold and the detection value of the second temperature sensor 133B is less than the fourth target threshold, the control instruction can be used to control the first valve 101 to close and control the second valve 102 to open.

[0099] The third target threshold may be an upper limit value for normal operation of the hydrogen production device 110 , the fourth target threshold may be a lower limit value for normal operation of the electrochemical energy storage device 120 , and the third target threshold must be greater than the fourth target threshold.

[0100] It can be understood that within the temperature range from the first target threshold to the third target threshold, the hydrogen production equipment 110 can operate normally and effectively without causing performance degradation or damage due to overheating; within the temperature range from the fourth target threshold to the second target threshold, the electrochemical energy storage device 120 can operate normally and effectively without causing performance degradation or damage due to overheating.

[0101] In actual implementation, Figure 1-Figure 3 As shown, the first temperature sensor 133A and the second temperature sensor 133B can feed back the detection values ​​to the first comparator, and the first comparator can compare the detection value of the first temperature sensor 133A with the third target threshold and compare the detection value of the second temperature sensor 133B with the fourth target threshold to obtain a comparison result. The first comparator can feed back the comparison result to the first processor. When the comparison result is that the detection value of the first temperature sensor 133A is greater than the third target threshold and the detection value of the second temperature sensor 133B is less than the fourth target threshold, in response to the comparison result, the controller 134 can control the first valve 101 to close, and control the second valve 102 to open.

[0102] It should be noted that, under normal circumstances, the first valve 101 is in an open state, and the second valve 102 is in a closed state.

[0103] The thermal management system provided in the embodiment of the present application realizes data processing of the detection values ​​of the first temperature sensor 133A and the second temperature sensor 133B, and outputs instructions for the first valve 101 and the second valve 102 through the settings of the above-mentioned second comparator and the second processor, thereby providing hardware support for numerical comparison. When the hydrogen production equipment 110 is overheated and the electrochemical energy storage equipment 120 is overcooled, the hydrogen production equipment 110 is prompted to indirectly heat the electrochemical energy storage equipment 120, thereby improving the control accuracy of the joint thermal management between the hydrogen production equipment 110 and the electrochemical energy storage equipment 120.

[0104] In some embodiments, Figure 3 As shown, the thermal management system may further include a heat sink 136 .

[0105] The radiator 136 can be selectively connected to both the first heat exchange circulation loop 131 and the second heat exchange circulation loop 132 .

[0106] The radiator 136 may include, but is not limited to, an air-cooled radiator, a water-cooled radiator, or a heat pipe radiator, etc., which is not limited here.

[0107] For example, in some embodiments, the heat sink 136 is an air-cooled heat sink.

[0108] It is understandable that when the hydrogen production equipment 110 is at an abnormally high temperature and the temperature of the electrochemical energy storage equipment 120 is relatively low, although the electrochemical energy storage equipment 120 can exchange heat with the hydrogen production equipment 110 through the first heat exchange circulation loop 131, the heat exchanger 135 and the second heat exchange circulation loop 132, the cooling capacity that the electrochemical energy storage equipment 120 can provide is still insufficient for the abnormally high temperature hydrogen production equipment 110; similarly, when the electrochemical energy storage equipment 120 is at an abnormally high temperature and the temperature of the hydrogen production equipment 110 is relatively low, although the hydrogen production equipment 110 can exchange heat with the electrochemical energy storage equipment 120 through the first heat exchange circulation loop 131, the heat exchanger 135 and the second heat exchange circulation loop 132, the cooling capacity that the hydrogen production equipment 110 can provide is still insufficient for the abnormally high temperature electrochemical energy storage equipment 120.

[0109] In actual implementation, when the detection value of the first temperature sensor 133A is abnormally too high, the radiator 136 is connected to the first heat exchange circulation loop 131, so that the radiator 136 can cool the hydrogen production equipment 110. When the detection value of the first temperature sensor 133A is abnormally too high and the detection value of the second temperature sensor 133B is too low, the heat exchanger 135 is connected to the first heat exchange circulation loop 131 and the second heat exchange circulation loop 132, and the radiator 136 is connected to the first heat exchange circulation loop 131, so that the electrochemical energy storage device 120 and the radiator 136 can cool the hydrogen production equipment 110. Heat dissipation: When the detection value of the second temperature sensor 133B is abnormally too high, the radiator 136 is connected to the second heat exchange circulation loop 132, so that the radiator 136 can dissipate heat and cool the electrochemical energy storage device 120; when the detection value of the first temperature sensor 133A is too low and the detection value of the second temperature sensor 133B is abnormally too high, the heat exchanger 135 is connected to the first heat exchange circulation loop 131 and the second heat exchange circulation loop 132, and the radiator 136 is connected to the second heat exchange circulation loop 132, so that the hydrogen production equipment 110 and the radiator 136 can jointly dissipate heat for the electrochemical energy storage device 120.

[0110] The thermal management system provided in the embodiment of the present application is used in combination with the heat exchanger 135 through the setting of the above-mentioned radiator 136. When one of the hydrogen production equipment 110 and the electrochemical energy storage equipment 120 is abnormally high in temperature and the other is relatively low in temperature, the radiator 136 can further perform a second heat dissipation on the abnormally high temperature equipment on the basis of heat exchange between the hydrogen production equipment 110 and the electrochemical energy storage equipment 120, thereby realizing the mutual utilization of heat of the hydrogen production equipment 110 and the electrochemical energy storage equipment 120, improving energy utilization, and enhancing the energy efficiency ratio of the thermal management system. At the same time, it also fully prepares for the abnormal overheating of the hydrogen production equipment 110 and the electrochemical energy storage equipment 120, enriches the joint thermal management strategy of the hydrogen production equipment 110 and the electrochemical energy storage equipment 120, and comprehensively optimizes the safety performance of the hydrogen production energy storage system 100.

[0111] In some embodiments, Figure 3 As shown, the thermal management system may further include: a third valve 103 , a fourth valve 104 and a second branch 138 .

[0112] The third valve 103 can be arranged in the first heat exchange circulation loop 131, the second branch 138 can be connected in parallel with the third valve 103, the first branch of the radiator 136 can be connected to the second branch 138, the fourth valve 104 can be arranged in the second branch 138, and the fourth valve 104 can be located between the first branch of the radiator 136 and the hydrogen production equipment 110; wherein, the controller 134 can be electrically connected to the third valve 103 and the fourth valve 104, and the controller 134 can be used to control the third valve 103 and the fourth valve 104 based on the detection value of the first temperature sensor 133A.

[0113] In this embodiment, if Figure 3 As shown, the radiator 136 , the third valve 103 , the fourth valve 104 and the second branch 138 may be disposed between the outlet of the hydrogen production equipment 110 and the inlet of the heat exchanger 135 .

[0114] In other embodiments, the radiator 136 , the third valve 103 , the fourth valve 104 , and the second branch 138 may be disposed between the inlet of the hydrogen production equipment 110 and the outlet of the heat exchanger 135 .

[0115] In actual implementation, Figure 3 As shown, the first temperature sensor 133A can feed back the detection value to the controller 134, and the controller 134 can control the opening and closing states of the third valve 103 and the fourth valve 104 based on the detection value fed back by the first temperature sensor 133A. Specifically, when the third valve 103 is opened and the fourth valve 104 is closed, the cooling medium in the first heat exchange circulation loop 131 cannot flow through the first path of the radiator 136; when the third valve 103 is closed and the fourth valve 104 is opened, the cooling medium in the first heat exchange circulation loop 131 can flow through the first path of the radiator 136; when the third valve 103 and the fourth valve 104 are both opened, at least part of the cooling medium in the first heat exchange circulation loop 131 can flow through the first path of the radiator 136.

[0116] It should be noted that if the heat exchange amount of the hydrogen production equipment 110 needs to be controlled more accurately, the controller 134 can control the heat exchange amount per unit time by controlling the opening degrees of the third valve 103 and the fourth valve 104 .

[0117] The thermal management system provided in the embodiment of the present application, through the settings of the above-mentioned second branch 138, the third valve 103 and the fourth valve 104, realizes that the thermal management system adjusts the third valve 103 and the fourth valve 104 according to the operating temperature of the hydrogen production equipment 110 to increase the heat dissipation of the hydrogen production equipment 110, and can quickly dissipate a large amount of heat of the hydrogen production equipment 110 through the first path of the radiator 136, effectively improving the heat dissipation efficiency of the hydrogen production equipment 110. At the same time, the controller 134 can respond quickly and issue instructions after acquiring data, thereby improving the accuracy of thermal control and reducing the negative impact of continuous high temperature on the working performance of the hydrogen production equipment 110.

[0118] In some embodiments, the controller 134 may include: a third comparator and a third processor.

[0119] The third comparator can be used to compare the detection value of the first temperature sensor 133A with the fifth target threshold; the third processor can be electrically connected to the third comparator, and the third processor can be used to output a control instruction based on the comparison result, and the control instruction can be used to control the third valve 103 and the fourth valve 104.

[0120] The fifth target threshold may be an upper limit value for safe operation of the hydrogen production equipment 110 , and the fifth target threshold is greater than the third target threshold.

[0121] In actual implementation, Figure 3 As shown, the first temperature sensor 133A can feed back the detection value to the third comparator, and the third comparator can compare the detection value of the first temperature sensor 133A with the fifth target threshold to obtain a comparison result. The third comparator can feed back the comparison result to the third processor. When the comparison result is that the detection value of the first temperature sensor 133A is greater than the fifth target threshold, in response to the comparison result, the controller 134 can output a control instruction, and the control instruction can control the third valve 103 to close, and control the fourth valve 104 to open.

[0122] It should be noted that, under normal circumstances, the third valve 103 is in an open state, and the fourth valve 104 is in a closed state.

[0123] The thermal management system provided in the embodiment of the present application realizes data processing of the detection value of the first temperature sensor 133A and command output of the third valve 103 and the fourth valve 104 through the setting of the above-mentioned third comparator and the third processor, and provides hardware support for numerical comparison. In the case of abnormal overheating of the hydrogen production equipment 110, the radiator 136 is prompted to perform efficient and direct heat dissipation and cooling for the hydrogen production equipment 110, so that the thermal management system can be applicable to high-power hydrogen production equipment 110, thereby increasing the scope of use of the thermal management system.

[0124] In some embodiments, Figure 3 As shown, the thermal management system may further include: a fifth valve 105 , a sixth valve 106 and a third branch 139 .

[0125] The fifth valve 105 can be arranged in the second heat exchange circulation loop 132, the third branch 139 can be connected in parallel with the fifth valve 105, the second path of the radiator 136 can be connected to the third branch 139, the sixth valve 106 can be arranged in the third branch 139, and the sixth valve 106 can be located between the second path of the radiator 136 and the electrochemical energy storage device 120; wherein, the controller 134 can be electrically connected to the fifth valve 105 and the sixth valve 106, and the controller 134 can be used to control the fifth valve 105 and the sixth valve 106 based on the detection value of the second temperature sensor 133B.

[0126] In this embodiment, if Figure 3 As shown, the radiator 136 , the fifth valve 105 , the sixth valve 106 and the third branch 139 may be disposed between the outlet of the hydrogen production equipment 110 and the inlet of the heat exchanger 135 .

[0127] In other embodiments, the radiator 136 , the fifth valve 105 , the sixth valve 106 , and the third branch 139 may be disposed between the inlet of the hydrogen production equipment 110 and the outlet of the heat exchanger 135 .

[0128] In actual implementation, Figure 3 As shown, the second temperature sensor 133B can feed back the detection value to the controller 134, and the controller 134 can control the opening and closing states of the fifth valve 105 and the sixth valve 106 based on the detection value fed back by the second temperature sensor 133B. Specifically, when the fifth valve 105 is opened and the sixth valve 106 is closed, the cooling medium in the second heat exchange circulation loop 132 cannot flow through the second path of the radiator 136; when the fifth valve 105 is closed and the sixth valve 106 is opened, the cooling medium in the second heat exchange circulation loop 132 can flow through the second path of the radiator 136; when the fifth valve 105 and the sixth valve 106 are both opened, at least part of the cooling medium in the second heat exchange circulation loop 132 can flow through the second path of the radiator 136.

[0129] It should be noted that if the heat exchange amount of the electrochemical energy storage device 120 needs to be controlled more accurately, the controller 134 can control the heat exchange amount per unit time by controlling the opening degrees of the fifth valve 105 and the sixth valve 106 .

[0130] The thermal management system provided in the embodiment of the present application, through the settings of the above-mentioned third branch 139, the fifth valve 105 and the sixth valve 106, realizes that the thermal management system adjusts the fifth valve 105 and the sixth valve 106 according to the working temperature of the electrochemical energy storage device 120 to increase the heat dissipation of the electrochemical energy storage device 120, and can quickly dissipate a large amount of heat of the electrochemical energy storage device 120 through the second path of the radiator 136, effectively improving the heat dissipation efficiency of the electrochemical energy storage device 120. At the same time, the controller 134 can respond quickly and issue instructions after acquiring data, thereby improving the accuracy of thermal control and reducing the negative impact of continuous high temperature on the working performance of the electrochemical energy storage device 120.

[0131] In some embodiments, the controller 134 may include: a fourth comparator and a fourth processor.

[0132] The fourth comparator can be used to compare the detection value of the second temperature sensor 133B with the sixth target threshold; the fourth processor can be electrically connected to the fourth comparator, and the fourth processor can be used to output a control instruction based on the comparison result, and the control instruction can be used to control the fifth valve 105 and the sixth valve 106.

[0133] The sixth target threshold may be an upper limit value for safe operation of the electrochemical energy storage device 120 , and the sixth target threshold is greater than the second target threshold.

[0134] In actual implementation, Figure 3 As shown, the second temperature sensor 133B can feed back the detection value to the fourth comparator, and the fourth comparator can compare the detection value of the second temperature sensor 133B with the sixth target threshold to obtain a comparison result. The fourth comparator can feed back the comparison result to the fourth processor. When the comparison result is that the detection value of the second temperature sensor 133B is greater than the sixth target threshold, in response to the comparison result, the controller 134 can output a control instruction, and the control instruction can control the fifth valve 105 to close, and control the sixth valve 106 to open.

[0135] It should be noted that, under normal circumstances, the fifth valve 105 is in an open state, and the sixth valve 106 is in a closed state.

[0136] The thermal management system provided in the embodiment of the present application realizes data processing of the detection value of the second temperature sensor 133B and command output of the fifth valve 105 and the sixth valve 106 through the setting of the above-mentioned fourth comparator and the fourth processor, and provides hardware support for numerical comparison. In the case of abnormal overheating of the electrochemical energy storage device 120, the radiator 136 is prompted to perform efficient and direct heat dissipation and cooling for the electrochemical energy storage device 120, so that the thermal management system can be applicable to high-power electrochemical energy storage devices 120, thereby increasing the scope of use of the thermal management system.

[0144] The hydrogen production and energy storage system 100 is electrically connected to the new energy power generation system 200 .

[0145] It is understandable that if Figure 4 As shown, in the new energy hydrogen production and storage system 10, the new energy power generation system 200 can convert renewable energy into electrical energy, and the new energy power generation system 200 can provide this electrical energy to the hydrogen production equipment 110. In this way, the hydrogen production equipment 110 does not need an external power supply, and the hydrogen production equipment 110 can use this electrical energy to electrolyze water to obtain hydrogen and oxygen. This process combines new energy power generation and water electrolysis hydrogen production technology to realize the direct conversion and storage of renewable energy into hydrogen energy.
