[0024] Figure 1 The schematic diagram of a fuel cell engine system simulation device according to an exemplary embodiment of this application is shown. The following will be Figure 1 a detailed description of the fuel cell engine system simulation device of the exemplary embodiments of this application.

[0025] The fuel cell engine system simulation device according to the present application is used to simulate the output characteristics of a fuel cell engine to detect the functions of a fuel cell engine system test bench. The fuel cell engine system simulation device includes a water circuit system, an exhaust system, a hydrogen supply system, an electronic control system, and an electric energy output system. The water circuit system is used to simulate the water circulation in the fuel cell system and the heat generation of the engine to detect the cooling water temperature control and regulation ability of the test bench. The exhaust system is used to simulate the engine exhaust emissions (emissions of hydrogen and air) to detect the ability of the test bench to handle high-temperature and high-humidity air and hydrogen emissions under a specified pressure and to detect the hydrogen exhaust concentration. The hydrogen supply system is used to simulate hydrogen supply to debug the hydrogen supply pipeline, related sensors, and valve components of the test bench. The electronic control system supplies power to and controls the fuel cell engine system simulation device. The electric energy output system is used to simulate the power output of the engine with a high-power regulated power supply to detect the electronic load of the test bench.

[0026] The fuel cell engine system simulation device may further include a support frame. The water circuit system, the exhaust system, the hydrogen supply system, the electronic control system, and the electric energy output system are fixed to the support frame. The support frame can be built, for example, using an aluminum profile structure, which is convenient for pipeline fixing and upgrading and expansion. By fixing the various systems of the fuel cell engine system simulation device to the support frame, the effects of a compact structure, a small floor space, and a high degree of integration can be achieved.

[0027] The water circuit system simulates the engine circulating water circuit. As Figure 1As shown, the water circuit system includes a water pump 307, a heat exchanger 308, and a heater 311 on the main circulation pipeline between the water inlet B and the water outlet A. The water outlet A and the water inlet B are respectively connected to the water inlet and the water outlet of the test bench to form a circulation. When the water circuit system works, the water pumped out by the water pump 307 enters the test bench through the water inlet of the test bench connected to the water outlet A of the water circuit system, returns to the main circulation pipeline from the water inlet B after circulating in the test bench, flows through the heat exchanger 308 and the heater 311, and then flows out from the water outlet A and enters the water inlet of the test bench, thus forming a water circuit circulation between the test bench and the fuel cell engine system simulation device. In the main circulation pipeline, the heater 311 heats the flowing water, while the heat exchanger 308 dissipates the heat of the flowing water. By controlling the heating time of the heater 311 and the water flow rate on the cold side of the heat exchanger 308, the water temperature in the main circulation pipeline can be controlled. The water circuit system may include a cold-side water flow control valve 312 for controlling the water flow rate on the cold side of the heat exchanger 308. The heat exchanger 308 may be a plate heat exchanger, for example. The cold-side water flow control valve may be a proportional valve, for example. The water circulating in the main circulation pipeline exchanges heat with the cold-side water of the heat exchanger 308, thereby achieving heat dissipation. By controlling the opening degree of the cold-side water flow control valve 312, the water flow rate on the cold side of the heat exchanger 308 is controlled, and further the temperature of the water in the main circulation pipeline is controlled. When it is necessary to reduce the water temperature in the main circulation pipeline, the valve of the cold-side water flow control valve 312 can be opened wider, so that the water flow rate on the cold side of the heat exchanger 308 increases and the heat dissipation amount increases, thereby reducing the water temperature in the main circulation pipeline; when it is necessary to increase the water temperature in the main circulation pipeline, the valve of the cold-side water flow control valve 312 can be closed, thereby turning off the water flow rate on the cold side of the heat exchanger 308 and increasing the water temperature in the main circulation pipeline. The heater 311 heats the water in the main circulation pipeline. When it is necessary to increase the water temperature in the main circulation pipeline, the heater 311 heats the water in the main circulation pipeline. When it is necessary to reduce the water temperature, the heater 311 can stop heating.

[0028] Preferably, the water pump 307 is a variable-frequency water pump. By controlling the frequency of the frequency converter of the water pump 307, the rotation speed of the water pump is set, thereby changing the water flow rate. For example, the water flow rate of 9 m3 / h when a 60KW engine operates at full power can be simulated by controlling the frequency of the frequency converter of the water pump 307.

[0029] In the water circuit system, by controlling the water temperature in the main circulation pipeline and coordinating with the change of the water flow rate, the performance of the temperature control module of the test bench can be detected.

[0030] Optionally, a pressure sensor 301 and a temperature sensor 302 are provided near the water inlet B of the main circulation pipeline, a pressure sensor 303 and a temperature sensor 304 are provided near the water outlet A, and a temperature sensor 313 is provided at the heater 311, so as to be able to sense the temperature and pressure of the water at the corresponding positions in the main circulation pipeline. An electronic thermostat 300 may also be provided on the main circulation pipeline to control the flow rates of the large circulation and the small circulation. In addition, optionally, a flow meter 305 may also be provided on the main circulation pipeline to measure the water flow rate in the main circulation pipeline.

[0031] Optionally, the water circuit system further includes an exhaust / filling port C, and the exhaust / filling port C and the heater 311 are connected through an exhaust / filling pipeline to perform exhaust / filling.

[0032] The tail exhaust system includes a hydrogen tail exhaust system and an air tail exhaust system. The air tail exhaust system is used to simulate the air tail exhaust of the engine, and the hydrogen tail exhaust system is used to simulate the hydrogen tail exhaust of the engine. During testing, compressed air is usually used instead of hydrogen. Therefore, in the tail exhaust system of this application, compressed air is introduced from the compressed air inlet and then divided into two paths. One path leads to the air tail exhaust system for humidification to simulate the air tail exhaust, and the other path leads to the hydrogen tail exhaust system for humidification to simulate the hydrogen tail exhaust. The simulated air tail exhaust and hydrogen tail exhaust are sent to the tail exhaust inlet of the test bench, which is equivalent to the engine tail exhaust.

[0033] The air exhaust system includes a first humidifying tank 404. The first humidifying tank 404 is, for example, a bubbling humidifying tank. The first humidifying tank 404 is connected to the compressed air inlet of the exhaust system through a first air inlet pipeline, connected to a water source through a first water inlet pipeline, and connected to the first exhaust port E of the exhaust system through a first exhaust pipeline. An appropriate amount of water is added to the first humidifying tank 404 through the first water inlet pipeline. A first heater 414 may be provided on the first water inlet pipeline. The first heater 414 heats the water flowing through it, and the water temperature control of the first water inlet pipeline can be achieved by controlling the heating time of the first heater 414. The first heater 414 may be one or more, and the power may be, for example, 6KW. One or more first temperature sensors 409 may be provided at the connection of the first water inlet pipeline and the first humidifying tank 404. The start and stop of the first heater 414 can be controlled according to the temperature sensed by the temperature sensor 409 to maintain the water in the first humidifying tank 404 at a predetermined temperature, such as about 70°C. A temperature sensor 413 may be provided inside the first heater 414. A first heat exchanger 412 may also be provided on the first water inlet pipeline, and the first heat exchanger 412 dissipates heat from the water flowing through it. The water temperature control of the first water inlet pipeline can also be achieved by controlling the cold-side water flow of the first heat exchanger 412. A solenoid valve 416 may be provided on the first water inlet pipeline to control the on-off of the first water inlet pipeline. A water pump 415 may also be provided on the first water inlet pipeline to increase the water pressure. Level sensors 410 and 411 may be provided inside the first humidifying tank 404. A solenoid valve 408 for controlling drainage may also be provided on the first humidifying tank 404. If the level sensors 410 and 411 sense that the liquid level in the first humidifying tank 404 is too high, the solenoid valve 408 can be controlled to drain the water.

[0034] The compressed air enters the first humidifying tank 404 from bottom to top through the first air inlet pipeline for bubbling humidification, then reaches the first exhaust port E connected to the exhaust inlet of the test bench through the first exhaust pipeline, and enters the test bench through the exhaust inlet of the test bench, thereby simulating the air exhaust of the engine. The air exhaust system may be provided with a first air inlet pipeline flow control valve 405A, such as a proportional valve, on the first air inlet pipeline. The air flow in the first air inlet pipeline can be controlled through the first air inlet pipeline flow control valve 405A, and thus the air exhaust flow entering the test bench can be controlled. A flow meter 405 may also be provided on the first air inlet pipeline to measure the air flow flowing through the first air inlet pipeline. In addition, a temperature sensor 403 may be provided at the connection of the first exhaust pipeline and the first humidifying tank 404. Temperature sensors 402 and a pressure sensor 406 may be provided on the first exhaust pipeline, and a pressure sensor 407 may be provided on the first air inlet pipeline.

[0035] The hydrogen tail gas exhaust system includes a second humidifying tank 206. The second humidifying tank 206 is, for example, a bubbling humidifying tank. The second humidifying tank 206 is connected to the compressed air inlet of the tail gas exhaust system through a second intake air pipe, connected to a water source through a second water inlet pipe, and connected to the second exhaust port F of the tail gas exhaust system through a second exhaust pipe. An appropriate amount of water is added to the second humidifying tank 206 through the second water inlet pipe. A second heater 218 is provided on the second water inlet pipe. The second heater 218 heats the water flowing through it. The water temperature control of the second water inlet pipe can be achieved by controlling the heating time of the second heater 218. The second heater 218 can be one or more, and the power can be, for example, 6KW. One or more second temperature sensors 209 can be provided at the connection of the second water inlet pipe and the second humidifying tank 206. The start and stop of the second heater 218 can be controlled according to the temperature sensed by the temperature sensor 209 to maintain the water in the second humidifying tank 206 at a predetermined temperature, such as about 70°C. A temperature sensor 211 can be provided inside the heater. A second heat exchanger 210 can also be provided on the second water inlet pipe. The second heat exchanger 210 dissipates heat from the water flowing through it. The water temperature control of the second water inlet pipe can be achieved by controlling the cold-side water flow of the second heat exchanger 210. A solenoid valve 213 can be provided on the second water inlet pipe to control the on-off of the second water inlet pipe. A water pump 212 can also be provided on the second water inlet pipe to increase the water pressure. Level sensors 215 and 216 can be provided inside the second humidifying tank 206. A solenoid valve 214 for controlling drainage can also be provided on the second humidifying tank 206. If the level sensors 215 and 216 sense that the liquid level in the second humidifying tank 20 is too high, the solenoid valve 214 can be controlled to drain the water.

[0036] The compressed air enters the second humidifying tank 206 from bottom to top through the second intake air pipe for bubbling humidification, then reaches the second exhaust port F connected to the tail gas exhaust inlet of the test bench through the second exhaust pipe, and enters the test bench through the tail gas exhaust inlet of the test bench, thereby simulating the hydrogen tail gas exhaust of the engine. The hydrogen tail gas exhaust system can be provided with a second intake air pipe flow control valve 201A, such as a proportional valve, on the second intake air pipe. The flow rate of the air in the second intake air pipe can be controlled through the second intake air pipe flow control valve 201A, and then the flow rate of the hydrogen tail gas exhaust entering the test bench can be controlled. A flow meter 201 can also be provided on the second intake air pipe to measure the air flow rate flowing through the second intake air pipe. In addition, a temperature sensor 208 can be provided at the connection of the second exhaust pipe and the second humidifying tank 206. Temperature sensors 203 and pressure sensors 202 can be provided on the second exhaust pipe.

[0037] In this application, bubbling humidification is carried out through a humidification tank at a certain liquid level. By controlling the start and stop of the heater according to the temperature sensor at the humidification tank, the temperature inside the humidification tank can be maintained at a predetermined temperature, such as about 70 °C. The tail gas discharge flow is controlled by controlling the flow control valve. For example, the tail gas discharge flow of a 30KW engine can be simulated up to 2500 slpm, and that of a 60KW engine can be simulated up to 5000 slpm. After bubbling humidification and mixing with hydrogen, it is introduced into the test bench to detect the hydrogen tail gas concentration, and / or to detect the high-temperature and high-humidity air and hydrogen discharge capacity of the test bench under a specified pressure.

[0038] The hydrogen supply system simulates hydrogen supply to debug the hydrogen supply pipeline, related sensors and valve parts of the test bench. The hydrogen supply system includes a hydrogen pipeline connected to the hydrogen inlet D, and a flow meter 204 and a hydrogen pipeline flow control valve 205 provided on the hydrogen pipeline. The hydrogen pipeline flow control valve 205 can be a proportional valve, for example. The hydrogen supply system simulates the hydrogen intake of the engine. Hydrogen enters the hydrogen pipeline of the hydrogen supply system of the fuel cell engine system simulation device from the test bench through the hydrogen inlet D connected to the hydrogen supply pipeline of the test bench. The flow meter 204 measures the hydrogen flow in the hydrogen pipeline, and the hydrogen pipeline flow control valve 205 adjusts the hydrogen flow in the hydrogen pipeline, and then vents it. By comparing the reading of the flow meter 204 with the reading of the flow meter in the hydrogen supply pipeline of the test bench, it is possible to detect whether the hydrogen supply, pressure sensor and flow meter of the test bench meet the requirements. During testing, nitrogen is often used instead of hydrogen. In this case, the gas flowing through the hydrogen inlet D, hydrogen pipeline, flow meter 204 and hydrogen pipeline flow control valve 205 is nitrogen.

[0039] The electronic control system is connected to the electrical equipment in the fuel cell engine system simulation device and is used to supply power and control the electrical equipment in the fuel cell engine system simulation device. The above-mentioned electrical equipment is, for example, a water pump, valve, heater, sensor, etc. The electronic control system can include a power supply module and a control module. The power supply module supplies power to the electrical equipment in the fuel cell engine system simulation device. The power supply module can be a storage battery, for example. The control module controls the electrical equipment in the fuel cell engine system simulation device. The control module can be a host computer, for example. The control module can be communicatively connected to the test bench. The control module can work in manual mode or automatic mode. In manual mode, the control module controls each component of the fuel cell engine system simulation device separately; in automatic mode, after the test bench sends a startup command and a target power to the fuel cell engine system simulation device, the fuel cell engine system simulation device sets the control parameters of the above-mentioned components according to the target power according to a preset value; at the same time, the state of the fuel cell engine system simulation device is sent to the test bench according to the communication protocol of the fuel cell engine.

[0040] The electric energy output system simulates the electric power output of an engine. The electric energy output system includes a high-power voltage-stabilized power supply, such as a 200kW DC adjustable power supply. When the fuel cell engine system simulation device works, the high-power voltage-stabilized power supply is connected to the electronic load of the test bench. The high-power voltage-stabilized power supply outputs direct current, and it can detect whether the electronic load of the test bench meets the requirements.

[0041] The fuel cell engine system simulation device of the present application can simulate the operating conditions of a fuel cell engine system (especially a 30 / 60kW fuel cell engine system). It can perform the detection of the test bench without integrating a set of fuel cell engine systems, so it can save costs.

[0042] The fuel cell engine system simulation device of the present application can accurately simulate the operating conditions of hydrogen supply, air supply, cooling water supply, heat generation, and electric energy output of a fuel cell engine system (especially a 30 / 60kW fuel cell engine system).

[0043] In addition, the fuel cell engine system simulation device of the present application also has the advantages of a compact structure, a small occupied space, and a high integration level.

[0044] In the description of the present application, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description. Without contrary instructions, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present application; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0045] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation other than the orientation described in the figure for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will be positioned as "below other devices or structures" or "under other devices or structures" afterwards. Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations are made for the spatial relative descriptions used here.

[0046] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional declaration, these terms have no special meaning, and thus should not be construed as a limitation on the scope of protection of this application.

[0047] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0048] The above are only the preferred embodiments of this application and are not used to limit this application. For those skilled in the art, this application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included within the scope of protection of this application.
