Detailed implementation manners

[0051] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different accompanying drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with this application. On the contrary, they are merely examples of devices and methods consistent with some aspects of this application as detailed in the appended claims.

[0052] Existing mobile hydrogen refueling stations face multiple challenges when operating in low-temperature environments. First, the viscosity of the hydraulic oil in the liquid-driven compressor significantly increases in low-temperature environments, which may cause difficulties in the normal startup of the hydraulic pump station and thus affect the operating efficiency of the compressor. Second, many precision instruments equipped in the hydrogen refueling station are easily affected by low temperatures, resulting in measurement errors or damage, threatening the safe operation of the hydrogen refueling station. Third, extremely low-temperature environments may also cause materials to contract due to cold, resulting in gaps at mechanical mating parts, thereby triggering leakage of pipe and valve components and further reducing the reliability of the equipment. In addition, the selection of low-temperature-resistant pipe and valve component materials to adapt to low-temperature environments significantly increases the construction cost of the hydrogen refueling station. These problems severely limit the safety, reliability, and operating efficiency of mobile hydrogen refueling stations in cold regions.

[0053] Aiming at problems such as the increase in the viscosity of hydraulic oil, instrument measurement errors, and cold shrinkage of pipe and valve components in low-temperature environments in the prior art, this technical solution designs an intelligent heating control method. The antifreeze is heated by an explosion-proof chiller, and the liquid-driven compressor, instruments, and pipe and valve components are precisely heated to ensure the normal startup of the hydraulic system, the precise operation of the instruments, and the equipment sealing performance, thereby improving the safety and reliability of the hydrogen refueling station in low-temperature environments.

[0054] The following uses specific embodiments to elaborate in detail on the technical solution of this application and how the technical solution of this application solves the above technical problems. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following will describe the embodiments of this application in conjunction with the accompanying drawings.

[0055] Figure 1 It is a schematic flowchart of Embodiment 1 of the heating control method for the mobile hydrogen refueling station provided in this application. As Figure 1 shown, the method includes:

[0056] S101. Obtain the working status information and compressor temperature of the mobile hydrogen refueling station.

[0057] Among them, the mobile hydrogen refueling station refers to a mobile device for hydrogen refueling, which is often used to provide hydrogen for hydrogen energy-using devices such as fuel cell vehicles. The working status information refers to the current working status of the mobile hydrogen refueling station, including the non-working status or the normal working status. The non-working status means that the mobile hydrogen refueling station is in a closed or standby state when it does not work for a long time, and the normal working status means that the mobile hydrogen refueling station is performing hydrogen refueling operations or is in a normal operating state.

[0058] The compressor temperature refers to the temperature inside or around the compressor. The compressor usually generates a relatively high temperature during operation, so it needs to be monitored and controlled to ensure that the compressor is within a reasonable working temperature range.

[0059] Specifically, sensors or monitoring devices can be used to determine whether the mobile hydrogen refueling station is in a normal working state or not. At the same time, devices such as temperature sensors can be used to obtain the temperature of the compressor in the mobile hydrogen refueling station, and this temperature value may be affected by various factors such as the ambient temperature.

[0060] S102. Determine whether the compressor temperature meets the compressor temperature requirement according to the working state information of the mobile hydrogen refueling station.

[0061] Among them, the compressor temperature requirement includes the first compressor temperature requirement or the second compressor temperature requirement. The first compressor temperature requirement is the temperature requirement for the compressor when the mobile hydrogen refueling station is in a non-working state. Generally speaking, the temperature of the compressor in the non-working state is relatively low, so it is required that the temperature cannot be lower than a certain requirement to avoid problems such as hydraulic oil freezing due to too low temperature. The second compressor temperature requirement is the temperature requirement for the compressor when the mobile hydrogen refueling station is in a normal working state. At this time, the temperature should be maintained within a suitable range, neither too low nor too high, to ensure the efficient operation of the compressor.

[0062] Specifically, according to the obtained working state information of the mobile hydrogen refueling station, it is judged whether the compressor temperature meets the temperature requirement. If the working state information is the non-working state, it is judged whether the compressor temperature is lower than the minimum temperature requirement. If it is lower than the minimum temperature requirement, the compressor temperature needs to be raised to the specified value through the heating program. If the working state information is the working state, it is judged whether the compressor temperature is lower than the working required temperature. If it is lower than the working required temperature, the heating program is started to ensure that the compressor temperature rises to the appropriate working temperature range.

[0063] S103. If the compressor temperature does not meet the compressor temperature requirement, generate a heating control instruction.

[0064] Among them, the heating control instruction is used to complete the heating of the mobile hydrogen refueling station. Specifically, by controlling the start of the chiller heating program, the antifreeze in the mobile hydrogen refueling station is heated, thereby increasing the temperature of the compressor and preventing the mobile hydrogen refueling station from being damaged due to too low temperature.

[0065] The heating control method of the mobile hydrogen refueling station provided by the embodiment of the present application obtains the working state information and the compressor temperature to judge whether the mobile hydrogen refueling station needs temperature control, and then judges whether the compressor temperature meets the requirements according to the working state information. If it does not meet the requirements, it enters the heating control mode. In the case where the temperature does not reach the standard, the chiller heating program is started by generating a heating control instruction to ensure that the temperature is raised to the safe range, thereby ensuring the reliable operation of the mobile hydrogen refueling station in a low-temperature environment.

[0066] Figure 2Schematic diagram of the second embodiment of the heating control method for the mobile hydrogen refueling station provided by this application. As Figure 2 shown, on the basis of the Figure 1 embodiment, if the working state information of the mobile hydrogen refueling station indicates that the mobile hydrogen refueling station is in a non-working state, the method further includes:

[0067] S201. According to the heating control instruction, start the chiller heating program to heat the antifreeze in the mobile hydrogen refueling station.

[0068] Among them, the chiller is a device suitable for controlling the liquid temperature in the hydrogen refueling station. Usually, it is used to adjust the temperature of the antifreeze. When the system needs to increase the temperature of the antifreeze, the heating program of the chiller will be started. The start of this heating program will activate the heater, thereby heating the antifreeze.

[0069] The antifreeze is a liquid used to keep the liquid from freezing under low temperature conditions. It is commonly used in the compressor cooling system. Especially when the compressor needs to operate in a low temperature environment, the antifreeze can prevent the liquid from freezing and ensure the normal operation of the compressor.

[0070] Exemplarily, when the obtained working state information of the mobile hydrogen refueling station indicates that the mobile hydrogen refueling station is in a long-term non-working state, and when the ambient temperature detected by the temperature sensor drops below minus 15 degrees, the heating program of the chiller will be started according to the heating control instruction. The main function of this program is to start the heater to heat the antifreeze. Through this process, the problem of antifreeze freezing caused by too low ambient temperature is prevented. Specifically, in the non-working state, due to the long-term non-operation, the temperature of equipment such as the compressor cylinder block may drop. At this time, by starting the heating program of the chiller, it is ensured that the temperature of the antifreeze gradually rises, thereby avoiding damage to the equipment caused by low temperature.

[0071] S202. Collect the first temperature change of the compressor during the operation of the chiller heating program.

[0072] Among them, the first temperature change refers to the temperature change of the compressor during the heating process of the chiller after the heating program is started, that is, whether the temperature of the compressor rises during the heating process and the rising amplitude.

[0073] Exemplarily, after starting the chiller heating program, monitor the temperature change of the compressor in real time. For example, collect the temperature change data of the compressor during the heating process through the temperature sensor. The main purpose is to ensure the impact of the heating process on the compressor. If the temperature of the compressor reaches the set value or the temperature change meets the requirements, it can be judged that the heating effect is good.

[0074] S203. When the first temperature change of the compressor meets the first preset temperature change requirement, turn off the chiller heating program to complete the heating control of the mobile hydrogen refueling station.

[0075] Among them, the first preset temperature change requirement is a preset standard temperature change range. After the chiller heating program is started, the temperature change of the compressor will be monitored to determine whether the temperature change meets the preset standard.

[0076] Exemplarily, when the first preset temperature change requirement is 5°C, after the first temperature change of the compressor is collected, it will be compared with the first preset temperature change requirement. If it is detected that the temperature of the compressor rises to 5°C, it proves that the temperature change meets the first preset temperature change. At this time, the chiller heating program can be controlled to continue to execute for 5 minutes to ensure that the temperature of the compressor remains stable. If within these five minutes, the temperature in the compressor room drops to -15°C again, the chiller heating program will continue to execute. If the temperature in the compressor room remains above -15°C within 5 minutes, the chiller heating program can be turned off. In addition, the ambient temperature detector in the compressor room will continuously monitor the temperature. Once the temperature drops to -15°C again, the above heating process will be repeated to ensure the stable operation of the mobile hydrogen refueling station in a low-temperature environment.

[0077] The heating control method of the mobile hydrogen refueling station provided by the embodiment of the present application explains the heating control process of the mobile hydrogen refueling station when it is in an unoperated state. By starting the chiller heating program according to the heating control instruction, the temperature of the antifreeze is increased to prevent freezing. At the same time, the temperature change of the compressor is collected in real time during the chiller heating process. When the temperature change of the compressor meets the preset requirements, the heating program is turned off to complete the heating control, ensuring that the mobile hydrogen refueling station is protected from the low temperature through temperature control when it is in an unoperated state.

[0078] Figure 3 It is a schematic flowchart of the third embodiment of the heating control method of the mobile hydrogen refueling station provided by the present application. As Figure 3 shown, on the basis of Figure 1 the embodiment, if the working state information of the mobile hydrogen refueling station indicates that the mobile hydrogen refueling station is in a normal working state, the method further includes:

[0079] S301. According to the heating control instruction, turn on the chiller heating program to heat the antifreeze in the mobile hydrogen refueling station.

[0080] In this step, when the mobile hydrogen refueling station is in a normal working state and it is detected that the temperature of the compressor does not meet the second compressor temperature requirement, the chiller heating program is turned on according to the heating control instruction to heat the antifreeze.

[0081] S302. Collect the second temperature change of the compressor and the temperature change of the hydraulic oil in the fuel tank during the operation of the chiller heating program.

[0082] After the chiller starts the heating mode, it will continuously collect the second temperature change of the compressor and the temperature change of the hydraulic oil in the fuel tank. These temperature change data are used to determine whether the mobile hydrogen refueling station can effectively maintain the compressor temperature within a safe operating range. Only when the compressor temperature reaches the set range will the chiller heating program be turned off to ensure that the mobile hydrogen refueling station operates in a normal working state.

[0083] S303. When the second temperature change of the compressor and the temperature change of the hydraulic oil meet the second preset temperature change requirement, turn off the chiller heating program to complete the heating control of the mobile hydrogen refueling station.

[0084] When the temperature of the compressor reaches the preset target through the second temperature change, the chiller cooling program will be commanded to turn off and the heating operation will stop. This process marks the completion of temperature regulation, ensuring that the compressor and hydraulic oil operate within a suitable temperature range and preventing damage to the mobile hydrogen refueling station at low temperatures.

[0085] Exemplarily, when the temperature sensor in the compressor room detects that the temperature drops to -5°C, the chiller heating program will automatically start and collect the temperature inside the chiller in real time. If the temperature sensor inside the chiller detects that the antifreeze temperature rises to 5°C, the chiller will start immediately to heat the antifreeze in the compressor and the hydraulic oil in the fuel tank. When the temperature of the compressor rises back to 0°C and the temperature of the hydraulic oil in the fuel tank rises to 20°C, it proves that the temperature change meets the second preset temperature change. At this time, the chiller heating program can be controlled to continue to execute for 5 minutes to ensure that the temperatures of the compressor and hydraulic oil remain stable. Within these 5 minutes, if the temperature of the hydraulic oil drops to 15°C, the chiller heating program will continue to execute. If the temperature of the hydraulic oil remains above 15°C, the chiller heating program will be controlled to turn off. The fuel tank temperature detector will continuously monitor the oil temperature. Once the temperature drops to 15°C, the above heating process will be repeated to ensure that the hydraulic oil temperature is maintained in an ideal state, thereby realizing the rapid start of the pump station and the smooth operation of the compressor.

[0086] The heating control method of the mobile hydrogen refueling station provided by the embodiments of the present application explains the heating control process of the mobile hydrogen refueling station in a normal working state. By collecting the temperature of the compressor and the problem of the hydraulic oil in real time, it not only improves the energy efficiency but also ensures the reliability of the mobile hydrogen refueling station in a low-temperature environment, preventing damage or failure of the mobile hydrogen refueling station caused by low temperature.

[0087] Figure 4 It is a schematic structural diagram of the heating control device of the mobile hydrogen refueling station provided by the present application. As Figure 4As shown in the figure, the heating control device 40 of the mobile hydrogen refueling station includes:

[0088] A hydrogen dispenser 401, a chiller module 402, a compressor module 403, a gas unloading module 404, and a control module 405.

[0089] Among them, the hydrogen dispenser 401 is the core device for the mobile hydrogen refueling station to interact with vehicles and undertakes the metering function during the hydrogen refueling process. It automatically controls the hydrogen refueling operation and communicates with the control module 405 of the hydrogen refueling station and the vehicle hydrogen refueling interface in real time. Its main components include high-pressure hydrogen pipelines, safety accessories (such as gas filters, inlet valves, mass flow meters, etc.), and a control unit.

[0090] The main function of the chiller module 402 is to provide cooling for the hydrogen refueling station and heat the antifreeze through a heating unit. The chiller module 402 includes a water tank, an oil tank, a gas heat exchange unit, and an oil tank heat exchange unit. The water tank is filled with antifreeze, and the oil tank is filled with hydraulic oil. Among them, the heating unit is used to heat the antifreeze to maintain the temperature. The water tank is used to store the antifreeze to ensure that the antifreeze always remains fluid under low-temperature conditions. The oil tank is used to store hydraulic oil to ensure that the hydraulic system can work smoothly in cold weather. The chiller module 402 ensures the normal operation of the chiller by heating the antifreeze and the oil tank, prevents the influence of low temperature on the equipment and the oil, and improves the working reliability of the hydrogen refueling station.

[0091] The compressor module 403 is a key device of the hydrogen refueling station and is used for the compression and transportation of hydrogen. A temperature sensor is set in the compressor module 403 to monitor the internal temperature of the compressor in real time. Through temperature monitoring, it is ensured that the compressor operates within an appropriate temperature range, avoiding equipment damage or low operating efficiency caused by too low temperature, and ensuring the efficient operation of the hydrogen refueling station.

[0092] The control module 405 is used to execute the entire heating control process. It coordinates with each part of the chiller module 402, the compressor module 403, and the gas unloading module 404 to execute the heating control method. Through the automated control system, the control module 405 ensures that the hydrogen refueling station can always be maintained within an appropriate working temperature range under various working conditions, improving the automation level and operating efficiency of the mobile hydrogen refueling station.

[0093] Furthermore, a gas heat exchange unit and an oil tank heat exchange unit are set in the chiller module 402. An intake heat exchanger, a primary exhaust heat exchanger, and a secondary exhaust heat exchanger are set in the gas heat exchange unit, which are used to heat key components such as the compressor cylinder block, the gas heat exchanger, and the oil tank through the circulation of the antifreeze. Through heating, it is ensured that the gas temperature in the compressor and the pipeline is appropriate, preventing equipment failures caused by low temperature and ensuring the smoothness of the hydrogen refueling process.

[0094] Further, a fuel tank heat exchange unit is provided with a fuel tank heat exchanger and a temperature sensor to monitor the temperature of the hydraulic oil in the fuel tank, ensure that the hydraulic oil remains within the ideal temperature range, improve the stability and efficiency of the hydraulic system, and ensure that the compressor can be started at any time.

[0095] The heating control device of the mobile hydrogen refueling station provided by the embodiment of the present application not only improves the reliability of the hydrogen refueling station in low-temperature environments by ensuring that the temperatures of key components (such as hydraulic oil and antifreeze) are maintained within a suitable range, but also provides guarantee for the long-term stable operation of the equipment. In particular, by heating the water tank and the fuel tank, the efficient operation of the hydraulic system and the refrigeration system at low temperatures is ensured, effectively avoiding equipment damage and failures caused by low temperatures.

[0096] Figure 5 It is a schematic flow chart of the fourth heating control embodiment of the mobile hydrogen refueling station provided by the embodiment of the present application. As Figure 5 shown, the connection unit corresponding to the explosion-proof chiller is shown. Specifically, the explosion-proof chiller is equipped with an explosion-proof heater to provide heat for the system in extremely low-temperature environments. The built-in water tank stores antifreeze, and the antifreeze realizes heating between compressors and equipment through circulation. The fuel tank stores hydraulic oil to drive the compressor piston. An ambient temperature sensor is installed in the compressor room, an antifreeze temperature sensor is installed in the chiller, and a hydraulic oil temperature sensor is installed in the fuel tank. The working states of the sensors, the explosion-proof chiller, and the pneumatic ball valves are coordinated through the control module. In addition, multiple pneumatic ball valves are equipped in the pipeline to control the flow direction of the antifreeze, and the antifreeze flows through the heat exchanger to form a cycle with the compressor cylinder block.

[0097] When the mobile hydrogen refueling station is in an idle state, the specific process is as follows:

[0098] When the ambient temperature sensor detects that the temperature in the compressor room drops to -15°C, the heating control module automatically triggers the heating program of the explosion-proof chiller. The explosion-proof heater starts to heat the antifreeze in the water tank to ensure that the temperature of the antifreeze gradually rises. When the internal temperature sensor of the chiller detects that the temperature of the antifreeze reaches 5°C, the chiller starts to operate. At this time, the pneumatic ball valve of the gas heat exchanger pipeline opens, and the antifreeze starts to circulate. The pneumatic ball valve of the fuel tank heat exchanger pipeline remains closed.

[0099] After the antifreeze flows out of the water tank, it successively passes through the intake air heat exchanger, the primary exhaust heat exchanger, the secondary exhaust heat exchanger, and the compressor cylinder block. Then, the antifreeze returns to the water tank, forming a closed-loop continuous cycle. It should be noted that during the circulation of the antifreeze, the compressor cylinder block will be heated to raise the temperature of the hydraulic oil in the cylinder block, ensuring the fluidity of the hydraulic system in a low-temperature environment and preventing damage to the equipment caused by cooling shrinkage. On the other hand, the compressor room can be heated. The antifreeze releases heat to increase the ambient temperature of the compressor room, preventing measurement errors or leaks in equipment such as instruments and pipe valves due to low temperature.

[0100] When the ambient temperature of the compressor room rises to 5°C, the chiller stops working, and the pneumatic ball valve in the gas heat exchanger pipeline closes. The heater stops after a 5-minute delay to ensure temperature stability. If the temperature in the compressor room drops to -15°C again within the delay time, the chiller and the heater will be restarted, and the heating process will start over.

[0101] When the mobile hydrogen refueling station is in normal operation, the specific process is as follows:

[0102] When the ambient temperature sensor in the compressor room detects that the temperature drops to -5°C, the heating program of the chiller automatically starts, and the explosion-proof heater starts to heat the antifreeze in the water tank to ensure that the temperature of the antifreeze gradually rises. When the antifreeze temperature sensor detects that the temperature of the antifreeze in the water tank reaches 5°C, the chiller starts to operate, and the pneumatic ball valves in the gas heat exchanger pipeline and the oil tank heat exchanger pipeline are opened synchronously.

[0103] The antifreeze flows out of the water tank and is divided into two circulation paths. The first path is the gas heat exchange circulation. The antifreeze successively passes through the intake air heat exchanger, the primary exhaust heat exchanger, and the secondary exhaust heat exchanger, and finally surrounds the compressor cylinder block and then returns to the water tank. Through this circulation, the compressor cylinder block can be heated to raise the temperature of the hydraulic oil in the cylinder block, ensuring that the cylinder block maintains an appropriate working temperature range and effectively preventing damage to the cylinder block caused by low temperature. In addition, by releasing heat through the antifreeze flowing through each heat exchanger, the compressor room is heated to protect components such as instruments and pipe valves, preventing leaks or measurement inaccuracies caused by metal cold shrinkage.

[0104] Second path: Hydraulic oil heating cycle. The antifreeze flows through the tank heat exchanger to heat the hydraulic oil, ensuring the working performance of the hydraulic system at low temperatures. When the ambient temperature in the compressor room rises to 0°C, the pneumatic ball valve in the gas heat exchanger pipeline automatically closes to stop heating the compressor room. When the tank temperature sensor detects that the hydraulic oil temperature reaches 20°C, the chiller automatically stops running. The pneumatic ball valve in the tank heat exchanger pipeline closes, and the explosion-proof heater stops working after a 5-minute delay to ensure temperature stability. Additionally, during the delayed operation of the explosion-proof heater, if the hydraulic oil temperature drops to 15°C, the chiller and the pneumatic ball valve will automatically restart, and the antifreeze will recirculate. If the hydraulic oil temperature remains above 15°C continuously, the explosion-proof heater and the chiller stop working. Through the real-time monitoring of the temperature sensor, the automatic repeated heating process is ensured in a low-temperature environment to maintain the normal operating temperature of the compressor room.

[0105] The heating control method of the mobile hydrogen refueling station proposed in this embodiment realizes comprehensive temperature protection for the compressor cylinder block, hydraulic oil, and other equipment in a low-temperature environment through the cooperation of the chiller, explosion-proof heater, antifreeze circulation, and intelligent temperature control module, ensuring the efficient and stable operation of the mobile hydrogen refueling station. At the same time, the split-path heating and intelligent control strategy further improve the energy utilization efficiency, providing a reliable guarantee for the operation of hydrogen refueling stations in low-temperature regions.
