Description

Technical part

The invention falls within the field of power equipment. Specifically, it includes a hydrogen storage device, a safety device, a hydrogen storage system, a temperature control system, and a temperature control method for hydrogen-powered bicycles.

background technology

It is quite common to use hydrogen storage tanks as hydrogen storage. Whether hydrogen fuel cell systems or other products that use hydrogen fuel cells, a hydrogen supply is required. At present, hydrogen storage technologies can be mainly divided into three types: high pressure gas, liquid hydrogen and hydrogen storage alloy. Among them, high-pressure gas hydrogen storage has higher energy, weight and density, but larger volume and poor safety. Although the energy, weight and density of the liquid hydrogen storage mode are also high, the energy consumption for liquefaction is large. At the same time, insulated storage tanks must be used, which are generally suitable for large storage tanks; The energy, weight and density of the hydrogen storage alloy can meet the basic usage requirements, but its safety is relatively high.

In general application, a hydrogen storage alloy is more practical. Among them, the hydrogen storage alloy technology mainly uses the hydrogen storage tank as the hydrogen storage container. Regardless of whether it is a mobile vehicle using the hydrogen storage tank or a stationary or portable power supply system, after the hydrogen is supplied from the hydrogen storage tank, hydrogen needs to be supplemented. However, at this stage, the structure of the hydrogen storage device is not scientific and reasonable enough, and there is no appropriate safety mechanism to limit its development and spread.

Specific Embodiments

In the following description, a large number of specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be implemented without one or more of these details. In other examples, to avoid confusion with the invention, some technical features known in the art are not described.

Please refer 1 for the structure of the hydrogen storage device and its piping in the currently available technology, in which various function valves 400 are independent bodies, one end of which is connected to the cylinder 120 through piping, and the other end is connected to a multi-stage pressure reducing valve through B a pipeline, and then connected to the stack 300 to realize hydrogen charging, decompression and hydrogen extraction of the hydrogen storage cylinder, and hydrogen supply of the stack. As a result, the piping of hydrogen-powered bicycles is complex, intertwined, and makes subsequent maintenance difficult.

In order to simplify the piping arrangement and improve the rationality of the structure of the hydrogen energy bicycle, the present invention provides a safe low-pressure hydrogen storage device, comprising: a bottle body, a combination valve arranged at the air outlet of the bottle body, and a built-in The solid hydrogen storage material of the bottle body; the integrated connection structure between the cylinder body and the combined valve, instead of the piping connection or line connection, is directly installed and manufactured by the factory according to the design requirements The connection structure, including but not limited to screw fitting, Clamp fitting, welding and other tight connection methods, so that the hydrogen storage bottle and the combined valve form a closed cavity. A solid-state hydrogen storage material is stored in the closed cavity. After heating the solid-state hydrogen storage material, the stack is supplied with a pressure of 15-65kPa through the combined valve, so that the internal pressure of the hydrogen storage bottle is higher than that of the hydrogen storage bottle when it is not used. Small (low-pressure hydrogen storage in the general sense), it will not cause any harm to users.

In another embodiment, the combined valve is a multifunctional integrated valve, and the combined valve includes: a valve body, a connection port, an inflation port, an air outlet, a control valve, a safety valve, and a pressure control valve; the connection port is connected to the air outlet of the bottle body to transfer hydrogen into the valve body; the inflation port communicates with the connection port, takes in hydrogen in one direction and transfers it to the connection port; the air outlet communicates with the connection port, takes in hydrogen and connects it to a stack, and supplies 15-65 kpa of hydrogen to the stack, it should be noted that for those skilled in the art, on the premise of not affecting the realization of its function, the gas inlet and gas outlet are combined. Two is one; the control valve is located at the connection point of the inflation port, the air outlet and the connection port, and controls the opening and closing of the connection port and the inflation port passage, the connection port and the air outlet port; the safety valve is connected to the connection port to ensure that the internal pressure of the bottle body is regulated within the low pressure range of 1-3Mpa; the pressure control valve is arranged at the connection port and the air outlet passage to control the air pressure in the valve body. By combining multiple function valves to design a combination valve, the combination valve has reasonable design structure, high integration, good safety performance and long service life. It further simplifies the pipeline layout of the hydrogen energy bike, reduces the possibility of pipeline intertwining, and reduces the difficulty of subsequent maintenance.

In a further embodiment, a sealing connection with a shut-off function is included, and the sealing connection comprises two parts: a first connection and a second connection, the first connection being connected to the air outlet and the second connection being connected to the outlet via a pipe Chimney is connected for chimney gas supply. When the first connector is disconnected from the second connector, the first connector has the function of shutting off the flow to form an open circuit to avoid hydrogen leakage; when the second connector is inserted into the first connector, a passage is formed and connected hydrogen is supplied to the stack through a pipeline to the stack; by connecting the sealing joint to the valve port of the gas outlet, when the hydrogen storage device is transported or replaced, the first joint is in an open-circuit state, and the gas outlet of the combination valve is automatically closed, thereby improving the combination. The airtightness of the valve further reduces hydrogen leakage.

In another embodiment, the bottle body comprises an inner liner, a wrapping layer and an outer wrap in sequence from the inside out; the bottle body is made of aluminum alloy seamless material and aluminum alloy liner carbon fiber wrap composite material, and the volume is 1000-5000ml. Compared with traditional steel bottles, the weight can be reduced by 40%-70%, and at the same time, it has the Features of high safety and easy portability, and the aluminum alloy has unique corrosion resistance after oxidation.

In another embodiment, in order to realize that the hydrogen storage device can store hydrogen at a low pressure, the hydrogen storage device further includes a heating element and an electrical connection element. Among them, the adjustment of the heating element can pre-store the hydrogen storage device to a solid hydrogen storage material, the stored solid hydrogen storage material can be less, or the storage is liquid hydrogen, hydrogen storage powder, etc., the internal pressure of the hydrogen storage bottle is regulated to 1. In the low pressure range of -3 MPa, the hydrogen pressure supplied to the stack through the combined valve regulator is 15-65 kPa. When the heating element heats the internal solid hydrogen storage material, the pressure of the internal solid hydrogen storage material gradually increases due to the rise in temperature of the solid hydrogen storage material and the sealing of the hydrogen storage device and evaporates to hydrogen range and can therefore be used in high-voltage application scenarios. In this regard, the heating element extends from the bottom of the bottle body to the middle of the bottle body along the axial direction of the hydrogen storage device (that is, the longitudinal direction), and the extension length is limited, that is, not equal to the entire axial direction of the hydrogen storage device, so that when heated after inserting the element, the tip end of which, which can also be called a heating end, is separated from the bottle mouth of the bottle body, so as not to prevent the bottle mouth of the hydrogen storage device from transferring the solid hydrogen storage material to the outside.

It is understood that the heating element mentioned above extends into the hydrogen storage device, but is not limited to extending into the interior of the hydrogen storage device. Conversely, in the case of an irregular shape of the hydrogen storage device, the heating element protrudes into the outer center of the bottle body, while in the case of a regular shape of the hydrogen storage device, the heating element can protrude into the interior of the bottle body. or the heating element may be partially deep. To the outer center of the bottle body, the other part extends into the inner part of the bottle body, and the heat is transferred to the solid hydrogen storage material after heat is generated by contact conduction or radiation conduction, thereby heating the solid hydrogen storage material.

In a further embodiment, the bottle body is provided with a groove body embedded in the bottle body for arranging the heating element in the groove body. The tank body includes an inner layer and an outer layer, a first cavity is formed between the inner layer and the outer layer, and a heating medium is installed in the first cavity, and the heating medium includes, but is not limited to, water and silicone oil, heat transfer oil, as a conducting medium and also as a thermal insulation medium by configuring the thermal conduction path to heat the hydrogen storage device and the solid hydrogen storage material, thereby making the heating process of the solid hydrogen storage material more stable and safe. In the present invention, the heating medium is preferably water, since water has a higher specific heat capacity, the heating process is smoother, making the heating process of the solid hydrogen storage material more stable and safer.

In addition to the heating element, the hydrogen storage device further includes an electrical connection element electrically connected to the heating element and exposed to the bottle body. The power source of the heating element comes from the electrical connection element, and the electrical connection element is connected to an external power supply. After power-on, the external power supply transmits electrical energy to the electrical connection element, and then the electrical connection element transmits electrical energy to the heating element. After the electrical power is generated , the electrical energy is converted into heat, thereby heating the solid-state hydrogen storage material and increasing the pressure of the solid-state hydrogen storage material in the hydrogen storage device.

In contrast, when the temperature of the hydrogen storage device is too high, the pressure in the hydrogen storage device becomes too high, and hydrogen leakage or even explosion may occur. Therefore, the hydrogen storage device also includes a cooling element. The cooling element serves as an emergency protection element to reduce the internal temperature of the hydrogen storage device in the event of a sustained high temperature or fire, to quickly cool the solid hydrogen storage material and control the internal pressure of the hydrogen storage bottle is maintained in the low pressure range of 1-3 MPa , thereby realizing temperature relief and improving the safety performance of the hydrogen storage bottle. Specifically, when the temperature reaches the threshold, an instruction is triggered and sent to the cooling element. Based on the instruction, start the cooling element to cool the hydrogen storage bottle. The cooling element can take various forms, such as physical cooling (e.g., a circulating cooling system) or chemical cooling. In the present invention, the cooling element is preferably a chemical cooling element containing at least one endothermic reactant, and the endothermic reactant is an endothermic effect caused by a response to a trigger, such as when the temperature reaches a threshold, the ammonium salt, Nitrate dissolves in water, triggering an endothermic reaction and producing a cooling effect.

In a further embodiment, the hydrogen storage device further comprises a protective cover for protecting the gas outlet and the combined valve of the hydrogen storage device, wherein an identification label such as an RFID/QR code is printed on one side of the protective cover. Since the installation and placement direction of the hydrogen storage device is unique, in the present invention, the printing direction of the identification label is the same as the standard placement direction of the hydrogen storage device. The user can judge the orientation of the hydrogen storage device by identifying the direction of the label, and ensure that the installation and placement direction of the hydrogen storage device meets the requirements.

The above technical solutions are further elaborated below with reference to the attached drawings and specific embodiments.

Hydrogen storage device 100 including: cylinder 120, tank 121, heating layer 122, anti-slip groove 123, opening 124, receiving step 125, primary chamber 121a, inner layer 121b, outer layer 121c, heating element 126 and electrical connection element 127; The safety device 200 is a combination valve comprising valve 230, connection port 231, inflation port 232, safety valve 233, pressure control valve 234, gas outlet 235, control valve 236 and valve 237; A cooling element 150, a secondary chamber 151, a trigger separator 152, a sealing connection 240 and a first connection 2410; protective cover 160, protective cover 161, identification label 162, low pressure gas outlet 163; Handle 170, Mounting Slot 171, Handle 172, Slide 173 and Connecting Rod 174.

Referring to FIGS. 2-4, in this embodiment, the heating element 126 does not extend into the interior of the cylinder 120, that is, the method of heating the heating element 126 for the solid hydrogen storage material is indirect conduction heating rather than direct contact heating. For this purpose, the cylinder 120 is provided with a container 121 along its axis. The tank 121 can be formed by extending the bottom of the cylinder 120 to the inside of the cylinder 120, but the cylinder 120 remains closed as a whole, and the irregular shape formed by the extension part is the tank 121. Hence the tank 121 is separated from the inside of the cylinder 120 by the wall of the cylinder 120, so that the tank 121 is separated from the inside of the cylinder 120 and the tank 121 is still connected to the outside of the cylinder 120.

Wherein the tank is a double layer structure comprising an inner layer 121b and an outer layer 121c, with a clearance reserved between the inner layer 121b and the outer layer 121c to form a closed primary chamber 121a. The primary chamber 121a is filled with a heating medium serving as both a conducting medium and a heat insulating medium. The media heats the hydrogen storage device and the solid hydrogen storage materials through a thermal conduction path, making the heating process of solid hydrogen storage materials more stable and safer.

With the tank 121, the heating element 126 penetrates into the tank 121 and fits into the tank 121 with a clearance, that is, the outer surface of the heating element 126 is in close contact with the inner wall of the tank 121 heating element 126 generates heat, heats the heating element 126 the thermal medium first before heating the cylinder 120 and transferring the heat from the cylinder 120 to the solid hydrogen storage material. The heating medium is preferably water because of its higher specific heat capacity than water. The heating process of water is more smooth, which can slow down the heating efficiency of solid hydrogen storage materials, but allows precise control of the heating temperature for solid hydrogen storage materials.

It should be understood that the heating element 126 and the tank 121 need not be engaged with the inside diameter of the tank 121 at every point on the side of the heating element 126 . The outer surface of the heating element 126 can also be designed in such a way that it is wavy or zigzag. The high parts of the zigzag lines or the crests of the waves touch the tank 121. Between the bottom part of the tooth (or the valley of the waves) and the inner wall of the tank 121 is an air layer, both a thermal insulation layer and a conductive layer. The heat generated by the heating element 126 can be indirectly transferred to the cylinder 120 through the air layer, and the overall heat transfer of the heating element 126 can also be controlled.

In addition, the heating end of the heating element 126 is far from the electrical connection element 127 and does not touch the tank 121 directly. In contrast, the length of the tank 121 along the axis of the cylinder 120 is greater than the length of the heating element 126 along the axis of the cylinder 120. Therefore, there is a heating layer 122 between the heating end of the heating element 126 and the bottom of the tank 121. The heating layer 122 is similar to the air layer, and the heat of the heating element 126 is transmitted to the cylinder 120 through the heating layer 122, thereby preventing excessive heating of solid hydrogen storage materials. That is, the heating layer 122 can serve as both a thermal conductor and a thermal insulator to slightly control the heating efficiency of the heating element 126 on the solid hydrogen storage materials.

By applying the heating element 126, the cylinder 120 and solid hydrogen storage materials, the heating process of the solid hydrogen storage material becomes more stable and safer.

On the other hand, the hydrogen storage device also includes a cooling element 150. The cooling element 150 is disposed within or to one side of the primary chamber 121a and separated from the primary chamber 121a by a trip separator 152 to form a secondary chamber 151. At least one endothermic reactant is formed within the secondary chamber 151 saved. In this embodiment, the endothermic reactant is ammonium salt and nitrate. At high temperature, trigger the trigger separator 152, connect the secondary chamber 151 and the primary chamber 121a, trigger the endothermic reactant, mix the ammonium salt and nitrate with water, cause the endothermic effect, reduce the temperature of the heating medium to the temperature of the cylinder and the solid hydrogen storage materials. This reduces the temperature of the cylinder and relieves the pressure.

The tripping separator 152 may be a baffle made of high temperature auto-melting material or a valve that is automatically opened by high temperature tripping. For example, the valve includes, but is not limited to, a magnetic switch. The magnetic material with a suitable Curie point is selected as the controller. The magnetic material can be a neodymium iron boron magnet. When the temperature is higher than the preset temperature, the magnetic material changes to paramagnetism to play the role of magnetic isolation. The partition is automatically deployed to connect the secondary chamber 151 and the primary chamber 121a and deploy the cooling element 150; In contrast, the initiating separator 152 remains isolated at all times.

The cooling element 150 can be automatically triggered by the materials with specific properties without the need for temperature alerts, which improves the response time of the cooling element 150, lowers the internal temperature of the hydrogen storage device, and controls the internal pressure of the device to maintain it in the low-pressure range of 1-3MPa.

When installing heater 126, the installation end of heater 126 is externally threaded and the notch of slot 121 is internally threaded; The male thread mates with the female thread to secure the heater element 126 in the tank 121. Optionally, the bottom of the cylinder 120 is flush with the notch of the tank 121 so that the bottom of the cylinder 120 is flat. When the hydrogen storage device 100 is placed, the bottom of the cylinder 120 can be attached directly to the placement surface. Unlike the shape of the hydrogen storage device 100 in the currently available technology, the installation is more convenient. In order to prevent the hydrogen storage device 100 from tipping over, at least one anti-slip groove 123 is provided on the lower end face of the cylinder 120 . The anti-slip groove 123 is arranged at a preset angle along the radial direction of the cylinder 120 or with the radial direction of the cylinder 110 arranged obliquely, for example, or the anti-slip groove 123 at multiple preset angles to generate friction in different directions and the anti-slip effect further to reinforce.

Preferably or optionally, the heating element 126 is a resistance wire and a temperature sensor is built-in or the temperature sensor is external to the resistance wire to sense the temperature of the resistance wire, allowing the user to monitor the heating process of the heating element 126 in real-time. On the other hand, the electrical connection element 127 has a plug-in interface into which an external power supply unit for receiving electrical energy is plugged.

A receiving step 125 is preferably or optionally arranged on the female electrical connection element 127 of the cylinder 120, and if the radial width of the receiving step 125 is greater than the radial width of the heating element 126, the heating element 126 can penetrate away from the receiving step 125 and the radial width of the electrical connector 127 conforms to the receiving step 125 so that when the electrical connector 127 is installed in contact with the receiving step 125, with the extension of the heating element 126, the electrical connector 127 passes through the receiving step 125 is blocked, the displacement that can extend to the center of the cylinder 120 is limited by the receiving step 125, and the part of the electrical connection member 127 protrudes from the cylinder 120, which is convenient for users to connect the external power supply . With the above design, the receiving stage 125 can be configured with a design that is additionally permanently connected to the electrical connector 127, such as snap-type, thread-type, etc., to further stabilize the installation relationship between the heating element 126 and the cylinder 120 and prevent the problem of expulsion of the heating element 126 after the internal pressure of the solid hydrogen storage material increases.

It goes without saying that the electrical connection element 127 must not protrude from the cylinder 120 in order to achieve the uniform overall shape of the hydrogen storage device 100, but rather, for example, is slightly recessed or flush with the receptacle is step 125. If the electrical connection element 127 on the receptacle step 125 is slightly set back , an additional sealing end can be placed on the receiving step 125. When the electrical connector 127 is not connected to the external power supply, the sealing end is sealed with the receiving step 125 and the electrical connector 127 is hidden inside, which can only be opened when it needs to be used.

Preferably or optionally, with reference to Figures 5 to 6, the hydrogen storage system also includes a safety device 200 using a combination valve located at the mouth of the cylinder 120; The combination valve includes a valve 230; The connection port 231 communicates with the gas outlet of the cylinder to transmit hydrogen to the valve 230; The inflation port 232 is connected to the connection port 231, receives hydrogen in one direction and transmits it to the connection port 231; The gas outlet 235 is connected to the connection interface 231, receives hydrogen, is connected to a stack and supplies hydrogen to the stack; A control valve 236 is arranged at the junction between the gas filling port 232, the gas outlet 235 and the connecting port 231 to control the opening and closing of the channel of the connecting port 231 and the gas filling port 232 and the connecting port 231 and the channel of the gas outlet 235; The safety valve 233 is connected to the connection interface 231 to ensure that the internal pressure of the cylinder is controlled within the low pressure range of 1-3MPa; The pressure control valve 234 is arranged at the connection interface 231 and the channel of the gas outlet 235 to control the gas pressure in the valve 230 . By combining and designing a variety of functional valves into a combined valve, the combined valve has reasonable design structure, high integration, good safety performance and long service life. It further simplifies the pipeline layout of hydrogen-powered bicycles, reducing pipeline tangles and the difficulty of future maintenance.

Preferably or optionally, the gas inlet 232 and the gas outlet 235 are combined to form a vent, and a two-way valve is arranged on the channel between the vent and the connection port 231 ensures the one-way hydrogen flow from the vent to the connection port 231; During the gas discharge process, the two-way valve ensures that hydrogen flows unidirectionally from connection port 231 to the vent. Alternatively, with reference to 6 two vent lines are disposed between the vent and the communication port 231, and one-way valves are disposed on the two vent lines, respectively. One one-way valve ensures gas supply to the electric stack and the other one-way valve ensures gas inflation to the cylinder. The design of the vent line inside the valve reduces the external connection interface of the combination valve, so that the valve has a high degree of integration, reasonable and compact structure, and light weight, reducing the risk of gas leakage.

Preferably or optionally, the sealing joint 240 has a flow disrupting function, and the sealing joint 240 comprises a first joint 2410 and two second joints; Wherein the first connector 2410 is connected to the gas outlet 235 and the second connector is connected to the stack by a tube for supplying gas to the stack. When the first connector 2410 is disconnected from the second connector, the first connector 2410 has the function of interrupting current to form an open circuit to prevent hydrogen leakage; When the second connector is inserted into the first connector 2410, a channel is formed and connected to the stack by tubing, and hydrogen is supplied to the stack; By connecting the sealing connector 240 to the valve hole of the gas outlet 235, the first connector 2410 is in the open during transportation and replacement of the hydrogen storage device Circulation state, and the gas outlet 235 is automatically closed, which improves the airtightness of the valve and further reduces hydrogen leakage.

Preferably or optionally, the hydrogen storage device also comprises a protective cover 160 comprising a protective cover 161 mounted on the gas outlet of the hydrogen storage cylinder and hermetically connected to the cylinder; An integrated structure is formed between the protective cover 161 and the combination valve. On the one hand, it serves to protect the gas outlet and the combination valve of the hydrogen storage tank; on the other hand, the protective cover 161 is combined with the combination valve to form a safety combination valve which can be used for safety control of gas leakage; On one side of the protective cover 161 an identification tag 162 such as an RFID/QR code is printed. A seal 240 on the other side of the protective cover 161 passes through the protective cover 161 and is exposed to the protective cover 161 to form a low pressure gas outlet 163 which conveniently connects to the second connector and provides low pressure hydrogen to the stack; Since the installation and placement direction of the hydrogen storage device is unique, the printing direction of the identification label 162 in the invention is the same as the standard installation and placement direction of the hydrogen storage device. The user can judge the directivity of the hydrogen storage device from the direction of the identification tag 162 to ensure that the installation direction of the hydrogen storage device meets the requirements.

When the above identification tag 162 is used, the user obtains the tag ID of the RFID/QR code associated with the hydrogen storage device through the scanning equipment, and then transmits it to the service terminal through the communication unit to provide the relevant information about the hydrogen receive hydrogen storage device, including but not limited to the following information: the hydrogen storage device number, the date of manufacture, the relevant parameters of the hydrogen storage device, the last hydrogen charging time and amount, and the hydrogen storage amount in the hydrogen storage medium. It should be noted that the above information is updated in real time with the processing, transportation and use of the hydrogen storage device.

Preferably or optionally, the identification tag 162 is permanently installed on the inside of the protective cover, and its identification area is exposed on the outside of the protective cover 161 through a hollow or transparent area intended for identification and information updating of identification devices on the protective cover 161. Based on the above design, the user can remove or install the identification tag 162 only under the premise that the protective cover 161 is opened. When the protective cover is installed on the cylinder, it is impossible to install or remove the identification tag 162 on the cylinder outside the protective cover. Therefore, it has better stability and avoids the identification tag 162 peeling off caused by human factors or natural factors.

Preferably or optionally, a handle 170 is installed on the cylinder 120 or the protective cover 161, and the handle 170 is a foldable handle 170. See in particular 7 . The handle includes a mounting slot 171 located inside or outside the cylinder barrel of the shell, a handle 172 hinged at one end to the top of the mounting slot 171, and an axial slide 173 located at the other end of the handle 172, a connecting rod 174 having one end hinged to the bottom of the mounting slot 171 and the other end clamped onto the slide groove 173. When the handle 170 is used, the user only has to pull out the lower part of the handle 172, and the connecting rod moves down, creating a gap between the handle 172 and the mounting slot 171, which forms the handle 170. On the other hand, when the handle 170 is not needed, the handle 172 only needs to be placed in the mounting slot 171, which greatly reduces the space occupied by the hydrogen storage device 100, and improves the transportation to the hydrogen storage efficiency in the process of batch transportation. It should be noted that the exemplary installation of handle 170 outside of cylinder 120 in 7 cannot be construed as limiting the installation position of the handle 170. For those skilled in the art, the handle 170 can be installed on the cylinder 120, the protective cover 161, or other locations suitable for installation.

After the hydrogen storage device is provided, it can be applied to hydrogen-powered bicycles. The hydrogen powered bicycle includes an engine and a stack connected to the engine. The stack is also connected to the hydrogen storage device to receive the discharged hydrogen to generate electric power using the hydrogen pressure.

With reference to 23 In order to improve the hydrogen desorption efficiency of the low-pressure hydrogen storage device, a temperature control system for the hydrogen storage device is shown. The hydrogen storage device includes a bottle body and a valve body placed at the air outlet of the bottle body. After the solid hydrogen storage material in the hydrogen storage device is heated, the stack is pressurized to 15-50 kPa through the valve Body pressure regulator When not in use, the internal pressure of the hydrogen storage device is low (low-pressure Hydrogen storage in the general sense), which does not cause any harm to users, and the storage can be liquid hydrogen, hydrogen powder, etc. When it is necessary to use or improve the internal hydrogen release efficiency, the hydrogen storage device can be heated. To this end, the temperature control system also includes temperature monitoring equipment and heating equipment. The temperature monitoring equipment is installed in the hydrogen storage device. For example, it can be used with the hydrogen storage device. A temperature sensor is fixed at the same position as the pressure valve of the pressure monitoring device, which is used as a temperature monitoring device when the temperature monitoring device works. It monitors the temperature in the bottle body of the hydrogen storage device, that is, directly monitors the solid-state hydrogen storage device in real time .The temperature of the material, for the temperature of the solid-state hydrogen storage material, the temperature monitoring device generates a temperature signal carrying the current temperature information of the solid-state hydrogen storage material. On the other hand, the heating device can be placed in the hydrogen storage device or outside the hydrogen storage device, and directly or indirectly heat the solid hydrogen storage material when working, for example, when the heating device is placed outside the hydrogen storage device, the heat generated by the heating device is first transferred to the bottle body and becomes passed to the solid hydrogen storage material; when the heater is placed inside the bottle body, the heat generated by the heater is directly transmitted or radiated to the solid-state hydrogen storage material, thereby increasing the temperature of the solid-state hydrogen storage material. Due to the closed nature of the hydrogen storage device, with constant quality, the solid state hydrogen storage material will also increase in pressure, ie, from a low pressure state to a high pressure state.

Since the solid-state hydrogen storage material cannot be heated indefinitely, the temperature control system also includes a temperature control module that is electrically connected to the temperature monitoring device or the heating device, with the temperature signal being formed by the temperature monitor and sent to the temperature control module. A temperature threshold is pre-stored in the temperature control module, and the temperature threshold reflects the expected operating temperature of the hydrogen storage device or the temperature of the solid hydrogen storage material therein with the expected rate of hydrogen desorption. The temperature control module compares the current temperature to the temperature threshold. When the current temperature information transmitted by the temperature signal is lower than the temperature threshold, it means that the temperature of the low-pressure solid-state hydrogen storage material is low. and the hydrogen release rate at that time will not reach the threshold. When expected, the temperature control module generates an activation command and sends it to the heater. Based on the activation command, the heater starts to work and heat solid-state hydrogen storage material in the hydrogen storage device, and the temperature of the solid-state hydrogen storage material will rise. After it is high, it will increase its hydrogen release rate to meet the needs of normal use.

In a preferred embodiment, the temperature control module includes a temperature comparison circuit, a heater control circuit, and a heater protection circuit. In particular, the temperature comparison circuit is electrically connected to the temperature monitoring device, and the above-mentioned temperature threshold (which can be a specific value or data range) is stored therein, which receives the temperature signal and compares the current temperature with the temperature threshold; the heater control circuit compares the temperature with the circuit and the heater are electrically connected, and the comparison results of the temperature comparison circuit, such as. B. the current temperature is greater than the temperature threshold, the current temperature is equal to the temperature threshold, the current temperature is less than the temperature threshold, etc., are sent to the heater control circuit, based on different comparison results, produce different For example, when the current temperature is greater than the temperature threshold or the current temperature is equal to the temperature threshold, it means that the hydrogen desorption rate in the hydrogen storage before direction is sufficient, and if the current temperature is lower than the temperature threshold, the activation command is generated; the heating protection circuit is set in the heating control circuit. The operating status of the entire temperature control module is monitored for the heating.

Further, the temperature control module also includes a clock unit that is electrically connected to the heating control circuit and adds clock information to the activation instruction, the clock information including the heating time t; the heating time t is calculated based on the following formula: t = (temperature threshold - current temperature) × time threshold / temperature threshold difference, the temperature threshold difference and the time threshold are pre-stored based on a test temperature and a test time. In addition to the above heating time t, the heating time t can also be set to a fixed value, within the set heating time t, the activation of the heater is maintained, and the activation is terminated after the heating time t is over. A weight value can also be added in the calculation formula of the heating time t, and the weight value adjusts the heating time t according to the scene used (regional information, seasonal information, etc.) to adjust the heating time t at any time according to different usage conditions.

Preferably, even when the heating device is activated, the heating state is adjusted in real time, for example, after the heating time t, the monitoring result of the temperature monitoring device on the hydrogen storage device is updated Current If the temperature is still lower than the temperature threshold, the temperature control module generates an activation command again and sends the activation command to the Heater to control the heater and keep working. It is understood that if the current temperature is still lower than the temperature threshold when reheating, the above steps are repeated until the current temperature is higher than or equal to the temperature threshold, that is, if it is within the heating time t that current temperature during the heating process is higher than If the temperature threshold is set, it means that the heat provided by the heating process is sufficient, then the temperature control module calculates the difference between the current temperature and the temperature threshold, and compares the difference with a preset difference that is pre-stored in the temperature control module The difference between the current temperature and the temperature threshold is greater than the preset difference, and the shutdown command is sent to the heating device within the heating time t in advance. This means that the heating effect is fulfilled within the heating time t and not only fulfilled exactly, but if there is a certain redundancy, the heating process is terminated prematurely.

In a preferred embodiment, the temperature monitoring device is a temperature sensor which is fastened in the bottle body and connected to the valve body and which can be arranged together with the pressure sensor for monitoring the pressure in the hydrogen storage device. The heater is in the form of a band and is placed on the outside of the bottle body. Or in other preferred embodiments, the heater extends into the bottle body for heating the hydrogen storage device, while the temperature monitor is attached to the heater and is integrally formed with the heater (the heater itself is a heating component with a temperature monitor) or a temperature monitor is installed on the heater . The end of the heater is provided with a connector, the tempering module has an electrical connector, and the electrical connector is inserted into the connector to connect with the heater. By supplying electrical energy to the heating device, the heating device turns on the electrical energy into thermal energy. In another embodiment, the electrical connector further comprises a heat conducting element, and the waste heat of the temperature monitoring device is transferred to the heating device through the heat conducting element. The heat compensation mechanism can further save energy.

The working state of the working state, the working state control logic is generated by the battery pack control unit. Preferably, the cell stack controller can also provide thermal energy to the temperature control system, ie the waste heat generated during operation of the fuel cell stack will offset the heat at the temperature monitoring device, thereby saving energy.

Referring to 8th until 10 In another embodiment, the hydrogen storage cylinder 180 of the hydrogen storage device 100 comprises a cylinder 181, multiple filter devices 183, a combination valve disposed outside the gas outlet of the cylinder 181, and a solid hydrogen storage material evenly distributed in the cylinder 181; The filter device 183 can be installed inside the gas outlet of the cylinder and at the bottom of the combined valve connection port, and is mainly used to isolate solid hydrogen storage materials. Compared to the person skilled in the art, the installation position of the filter device is not limited to the two locations mentioned above. The safety device 200 is a multifunction combination valve. The connection structure between the cylinder 181 and the combination valve is an integrated connection structure rather than a piping connection or pipe connection, which is directly installed and manufactured by the factory according to the design requirements. The connection structure includes, but is not limited to, thread fitting, press fitting, welding, and other connection methods such that the hydrogen storage device and the combination valve form a closed chamber. A solid hydrogen storage material is stored in the closed chamber. After the solid hydrogen storage material is heated, the hydrogen pressure supplied to the stack through the combination valve is 15-50kPa, so the internal pressure of the hydrogen storage device is low when not in use (generally low-pressure hydrogen storage). will not harm users.

In another embodiment, the connection port 231 is a two-way valve having one end connected to the hydrogen storage cylinder 180; The gas charging port 232 is a one-way valve. When the gas charging port 232 is connected to the external gas source, it can only flow unidirectionally from the external gas source to the hydrogen storage cylinder 180 instead of flowing toward the hydrogen storage cylinder 180, thereby ensuring the airtightness of the safety device 200; The gas outlet 235 is a pressure holding valve or a one-way valve, or a pressure holding valve is arranged at the connection port and the gas outlet passage. When the pressure in the hydrogen storage cylinder 180 is greater than the outside pressure, the gas outlet 235 is in the channel state.

In another embodiment, the sealing connection has a flow disrupting function, and the sealing connection comprises a first connection 2410 and a second connection; Wherein the first connector 2410 is connected to the gas outlet 235 and the second connector is connected to the stack 300 by a tube for supplying gas to the stack 300 . When the first connector 2410 is disconnected from the second connector, the first connector 2410 has the function of interrupting current to form an open circuit to avoid hydrogen leakage; When the second connector is inserted into the first connector 2410, a channel is formed and connected to the stack 300 by tubing to provide hydrogen to the stack 300; By connecting the sealing connector to the valve port of the gas outlet 235, the first connector 2410 is in the open circuit state when the hydrogen storage cylinder 180 is transported and replaced. The gas outlet of the safety device 200 is automatically closed, which improves the airtightness of the safety device 200, further reduces the leakage of hydrogen, and reduces the disassembly and installation of the leather hose.

In another embodiment, the safety device 200 is an integrated molded structure that exhibits superior sealing performance and structural stability. The safety device 200 is installed at the gas outlet of the hydrogen storage bottle 180; The connection between the safety device 200 and the hydrogen storage cylinder 180 is not a pipe connection or a line connection, but an integrated connection that is produced and installed directly at the factory according to the design specifications. The connection structure includes, but is not limited to, thread fitting, press fitting, welding, and other connection methods such that the hydrogen storage cylinder 180 and the safety device 200 form a closed chamber. A solid hydrogen storage material is stored in the closed chamber. After the solid hydrogen storage material is heated, the hydrogen pressure provided to the stack by the safety device 200 is 15-50 kPa, which makes the internal pressure of the hydrogen storage cylinder 180 smaller (generally low-pressure hydrogen storage) when not in use, and will not harm users inflict

In another embodiment, the cylinder 181 comprises a liner, wrap and jacket inside out; The cylinder 181 is made of seamless aluminum alloy material and aluminum alloy liner carbon fiber composite winding material with a volume of 1000-5000 ml. Compared with traditional steel cylinders, it can reduce the weight by 40% - 70% and features high security and easy transportation. In addition, an aluminum alloy has a unique resistance to corrosion after oxidation.

In another embodiment, referring to FIG. 9, the cylinder 181 is internally provided with a conduit 182 installed on the central axis of the cylinder 181, and a plurality of screens 184 are permanently installed along the conduit 182 at a predetermined spacing and angle . The cylinder 181 is divided into a primary chamber 185 and a secondary chamber 186 . The filter hole of the screen 184 is larger than the particle size of the solid hydrogen storage material, that is, only hydrogen is allowed to pass through, and the solid hydrogen storage materials are isolated; The primary chamber 185 and the secondary chamber 186 are arranged at intervals, and the volume of the primary chamber 185 is larger than that of the secondary chamber 186; A solid hydrogen storage material is stored in the primary chamber 185, and the volume of the solid hydrogen storage material is 60-90% of the volume of the primary chamber 185; A plurality of elastic balls 187 are arranged in the secondary chamber 186, the diameter of the elastic balls 187 is smaller than the height of the secondary chamber 186, and a vent hole connected at least to the secondary chamber is arranged on the conducting pipe 182. Preferably, the conducting pipe 182 is a mesh metal pipe, and that Metal pipe is made of aluminum alloy, titanium alloy or copper metal. On the one hand, the solid hydrogen storage material releases hydrogen, and the hydrogen flows from high pressure to low pressure. The first container, screen 184, secondary chamber 186, vent, conduit 182 and filter assembly 183 enter the safety assembly 200 through the connection port 231. FIG. On the other hand, the said conduction line can also increase the heat conduction and heat exchange efficiency of the hydrogen storage material, provide good heat exchange conditions for hydrogen absorption and release, reduce the cost of hydrogen absorption and release, and have better heat exchange effect and lower labor cost. In this embodiment, by laying solid hydrogen storage materials on the primary chamber 185, accumulation of solid hydrogen storage materials is avoided, and the contact area between hydrogen and solid hydrogen storage materials is increased. Regardless of the process of hydrogen charging or discharging, hydrogen charging and discharging can be realized faster and more comprehensively, fully showing the hydrogen storage performance of solid hydrogen storage materials. Since the hydrogen storage device in the invention is more commonly used in hydrogen-powered bicycles, it will inevitably bump when the bicycle is used. When the energy is transferred to the elastic ball 187, it obviously rebounds and lightly impacts the two sets of screens 184 located above and below the secondary chamber and the solid hydrogen storage material located above the screen 184. thereby causing the solid hydrogen storage material to tip over, thereby further improving the hydrogen storage performance of the solid hydrogen storage materials.

In another embodiment, since the hydrogen storage device is generally installed obliquely on the hydrogen-powered bicycles, referring to FIG. 10, the hydrogen storage device is installed obliquely on the support frame. Due to the inclined arrangement of the hydrogen storage device, the solid hydrogen storage materials will slip and eventually accumulate on the side of the cylinder 181 near the inclined direction, thereby reducing the specific surface area of the solid hydrogen storage materials is reduced. Referring to FIGS. 8 through 10, the included angle between the strainer 184 and the draft tube 182 is the same as the inclination angle of the hydrogen storage device, thereby ensuring that the direction of installation of the strainer 184 is parallel to the horizontal plane. By arranging the screen 184 horizontally, the solid hydrogen storage material can be loaded on the screen 184, and the specific surface area of the solid hydrogen storage material can be increased, so that hydrogen loading and hydrogen discharge can be achieved faster and faster. to fully showcase the hydrogen storage performance of the solid hydrogen storage material.

In another embodiment, due to the directivity on the screen 184, the direction of installation and placement of the hydrogen storage device is unique. Therefore, an identification tag is attached to the outer periphery of the hydrogen storage device. The setting direction of the identification plate is opposite to the direction of the gas outlet of the hydrogen storage, ie opposite to the direction of the hydrogen storage and opposite to the tilting direction; Users can judge the installation and placement direction of the hydrogen storage device by identifying the direction of the label, ensure that the installation and placement direction of the hydrogen storage device meets the requirements, avoid the accumulation of solid hydrogen storage materials, and give full play to the hydrogen storage performance of solid hydrogen storage materials. Of course, the identification tag can be an identification tag 162, a handle 170, or other conspicuous accessory; The identification tag 162 can be an RFID/QR code, for example.

In another embodiment, the hydrogen storage device also includes a protective cover 160 installed at the mouth of the hydrogen storage cylinder 180 to protect the gas outlet and the combination valve of the hydrogen storage device; An identification label 162 such as an RFID/QR code is printed on one side of the protective cover 160 . A sealing connector on the other side of the protective cover 160 passes through the protective cover 160 and is exposed to the protective cover 160 to form a low-pressure gas outlet that is convenient to connect to the second connector and provide low-pressure hydrogen to the stack; Since the installation and placement direction of the hydrogen storage device is unique, the printing direction of the identification label 162 in the invention is the same as the standard installation and placement direction of the hydrogen storage device. The user can judge the directivity of the hydrogen storage device from the direction of the identification tag 162 to ensure that the installation direction of the hydrogen storage device meets the requirements.

When the above identification tag 162 is used, the user obtains the tag ID of the RFID/QR code associated with the hydrogen storage device through the scanning equipment, and then transmits it to the service terminal through the communication unit to provide the relevant information about the hydrogen receive hydrogen storage device, including but not limited to the following information: the hydrogen storage device number, the date of manufacture, the relevant parameters of the hydrogen storage device, the last hydrogen charging time and amount, and the hydrogen storage amount in the hydrogen storage medium. It should be noted that the above information is updated in real time with the processing, transportation and use of the hydrogen storage device.

In another embodiment, the identification tag 162 is fixedly installed on the inside of the protective cover 160 and its identification area is exposed on the outside of the protective cover 160 through a cavity attached to the protective cover 160 for identification and information updating of identification devices. Based on the above design, the user can only remove or install the identification tag 162 provided that the protective cover 160 is opened. When the protective cover 160 is installed on the cylinder 181, the identification tag 162 cannot be installed and removed outside the protective cover 160. Therefore, it has better stability and avoids the identification tag 151 falling off caused by human negligence or natural factors .

In another embodiment, a handle 170 is installed on the cylinder 181 or the protective cover 160, and the handle 170 is a foldable handle 170. See particularly Figures 8-9. The handle 170 includes a mounting slot 171 located inside or outside of the housing of the cylinder 181 a handle 172 pivoted at one end to the top of the mounting slot 171 and an axial chute 173 located at the other end of the handle 172 and a connecting rod 174 hinged at one end bottom of the mounting slot 171 and the other End clamped on the sliding groove 173. When the handle 170 is used, the user need only pull out the bottom of the handle 172 and the connecting rod 174 moves downward so that there is a space between the handle 172 and the mounting slot 171 to form the handle 170. On the other hand, when the handle 170 is not needed, the handle 172 only needs to be placed in the attachment slot 171, which greatly reduces the occupied space and improves the hydrogen storage transport efficiency in batch transport. It should be noted that the exemplary installation of handle 170 outside of cylinder 181 in 9 and 10 cannot be construed as limiting the installation position of the handle 170. For those skilled in the art, the handle 170 can be installed in the cylinder 181, the protective cover 160, or other positions suitable for installation.

In another embodiment, in order to prevent the hydrogen storage device from tipping over, at least one anti-slip groove 188 is arranged on the lower end surface of the cylinder 181 in the radial direction of the cylinder 181 or with the radial direction of the cylinder 181, for example, arranged diagonally, or the anti-slip grooves 188 are arranged in plural preset angles to create friction in different directions, and further enhance anti-slip effect.

After the hydrogen storage device is provided, it can be applied to hydrogen-powered bicycles that include an engine and a stack connected to the engine. The stack is also connected to the hydrogen storage device to receive the discharged hydrogen to generate electrical energy using the hydrogen.

With reference to 12 , another preferred embodiment, two vent lines are placed between the vent port and the connection port 231, and one-way valves are placed respectively on the two vent lines, one one-way valve ensuring the gas supply to the stack. and a one-way valve provides inflation of gas into the cylinder. The design of the vent line inside the valve reduces the external connection interface of the combination valve, so that the valve has a high degree of integration, reasonable and compact structure, and light weight, reducing the risk of gas leakage.

In another embodiment, referring to Figures 13 to 14, the gas outlet of the gas outlet 235 is connected with a gasket connection; The sealing connection functions to stop flow and comprises a first connection 2410 and a second connection 2420; The first connector 2410 is connected to the gas outlet 235 and the second connector 2420 is connected to the stack 300 through a tube for supplying gas to the stack 300 . When the first connector 2410 is disconnected from the second connector 2420, the first connector 2410 has a current interrupting function to form an interrupt to prevent hydrogen leakage; When the second connector 2420 is inserted into the first connector 2410, a channel is formed and connected to the stack 300 by tubing to provide hydrogen to the stack 300; By connecting the sealing connector to the valve hole of the gas outlet 235, the first connector 120 is in the open-cycle state during transportation and replacement of the hydrogen storage device. The gas outlet of the safety device (combination valve) 200 is automatically closed, which improves the airtightness of the valve, further reduces hydrogen leakage, and at the same time, the hydrogen storage device is replaced quickly and conveniently.

In a further embodiment, the first port 2410 comprises: a first main section 2411 hermetically connected to the gas outlet 235, a second main section 2412 hermetically connected to the second port 2420, in which a sealing gas nozzle 2413 is arranged, second main section 2412 and an elastic member 2414 disposed outside the seal gas nozzle 2413; As the elastic member 2414 accumulates energy, the seal gas nozzle 2413 tends to remain closed.

Specifically, an annular first lip 2415 and a second lip 2416 are disposed on the outer surface of the first main portion 2411 and a predetermined gap is left between the first lip 2415 and the second lip 2416 . When the first main portion 2411 is connected to the gas outlet 235, due to the interference fit between the first lip 2415, the second lip 2416 and the gas outlet 235, a chamber, namely the first sealing chamber 2417, is formed between the first lip 2415 and the second lip 2416. Through the interference fit between the first lip 2415, the second lip 2416 and the gas outlet of the gas outlet 235 and the first seal Chamber 2417 creates the sealing connection between the gas outlet of the gas outlet 235 and the primary part 2411.

The seal gas nozzle 2413 includes a permanent portion 2413a permanently connected to the second main portion 2412, a bent portion 2413b connected to the permanent portion 2413a and inclined along the central axis of the first connection 2410, and a sealing portion 2413c connected to the bend is connected to section 2413b; The seal gas nozzle 2413 is an integrally formed structure. In addition, an annular elastic member 2414 is interposed between the sealing portion 2413c and the first main portion 2411 . The position of the elastic member 2414 is limited between the sealing portion 2413c and the first main portion 2411 . The position can be permanent or secured by the limiting member 2434 to ensure that the position of the elastic member 2414 does not slide relatively. Because the elastic member 2414 stores energy, the seal gas nozzle 2413 tends to remain closed. The cross-sectional shape of the elastic member 2414 of the invention is “W”, one end of which is in contact with the first main portion 2411 and the other end is in contact with the sealing portion 2413c. On the one hand, the elastic element 2414 stores energy, so that the sealing gas nozzle 2413 has a tendency to remain closed and can undergo some deformation; On the other hand, when the elastic member 2414 is deformed, the elastic member 2414 can also play the role of a sealing ring, because the outer surface of the elastic member 2414 is coated with a layer of flexible protective material, especially when the elastic member 2414 is deformed, the sealing effect can be improved be greatly improved.

In another embodiment, the second connector 2420 includes: a third main portion 2421 for sealing connection with the secondary main portion 2412; The fourth main section 2422 is hermetically connected to the gas supply line of the electric stack, and the upper pillar 2423 is placed inside the third main section 2421 and bulged outward and slack-fitted with the permanent section 2413a and the upper pillar 2423 is a hollow tube; When the second connector 2420 is inserted into the first connector 2410, the upper column 2423 raises the seal gas nozzle 2413, forces the seal gas nozzle 2413 to open, forms a path and supplies hydrogen to the gas supply line of the electrostack through a hollow tube.

Similarly, the outer surface of the third main portion 2421 is provided with an annular third lip 2424 and a fourth lip 2425 , and a predetermined gap is left between the third lip 2424 and the fourth lip 2425 . When the third main section 2421 is inserted into the first connector 120, the third lip 2424 and the fourth lip 2425 are an interference fit with the inner surface of the secondary main section 2412. Between the third lip 2424 and the fourth lip 2425 a chamber is formed, i.e. the second sealing chamber 2426. Also, a triangular cross-section groove 2418 is located on the inside of the secondary main section 2412, and an embedded element 2427 that mates with the recess is located on the outer edge of the third main section. The second connection 2420 and the first connection 2410 are sealed by embedding the embedded element 2427 in the groove portion 2418, the interference fit between the third lip 2424, the fourth lip 2425 and the inner surface of the secondary main portion 2412 and the second sealing chamber 2426.

It should be noted that the first port 2410 is always connected to the combination valve, so the tightness of the connection between the gas outlet 235 and the first main section 2411 is particularly important. Therefore, when the first connector 2410 is installed on the combination valve, an annular groove 2431 is placed outside of the gas outlet 235 and at a position that aligns with the first lip 2415 and the second lip 2416 . A locking element 2432 is installed on the ring groove 2431. The annular groove 2431 is transitionally equipped with the closing element 2432, which strengthens the closing of the sealing nozzle 2413 connection between the gas outlet 235 and the first main section 2411.

In another embodiment, the sealing gas nozzle 2413 exerts a rearward force on the upper column 2423 due to the energy storage effect of the elastic member 2414, so that the connection stability of the sealing joint during the gas transmission process becomes particularly important. Therefore, a buckle or clasp is arranged between the first connector 2410 and the second connector 2420 to ensure the connection stability of the first connector 2410 and the second connector 2420 . In the invention, a plurality of convex points 2433 are arranged on the outer surface of the upper pillar 2423, and a circular stopper 2434 corresponding to the convex tips 2433 is on arranged on the permanent portion 2413a; When installing the second connector 2420, slide the locking member 2432 to the side near the gas outlet 235, and then insert the second connector 2420 into the first connector 2410 can easily slide past the stopper 2434, and then the locking member 2432 to the side far from the gas outlet 235, preventing the convex tip 2433 from moving backwards. This operation secures the first connector 2410 and the second connector 2420.

Referring to FIGS. 15-17, in a preferred embodiment of the present invention, the hydrogen storage device comprises a bottle body and a solid hydrogen storage material built into the bottle body. It is made of seamless aluminum alloy material and carbon fiber wrapped aluminum alloy composite material, with a volume of 1000-5000ml. Compared with traditional steel bottles, the weight can be reduced by 40%-70%, and it has the characteristics of high safety and easy portability . , and the aluminum alloy has a unique corrosion resistance after oxidation.

The hydrogen storage device can store hydrogen at low pressure, and the hydrogen storage device also includes a heating element and an electrical connector. The adjustment of the heating element can pre-store the hydrogen storage device to a solid hydrogen storage material, the stored solid hydrogen storage material can be less, or the storage is liquid hydrogen, hydrogen storage powder, etc., the internal pressure of the hydrogen storage device is regulated to 1. Within the low pressure range of 3 MPa, the pressure of hydrogen supplied to the stack by the valve body pressure regulator is 15-50 kPa. When the heating element heats the internal solid hydrogen storage material, due to the increase in the temperature of the solid hydrogen storage material and the sealing of the hydrogen storage device, the pressure of the internal solid hydrogen storage material gradually increases and evaporates into hydrogen. In this regard, the heating element extends from the bottom of the bottle body to the center of the bottle body along the axial direction of the hydrogen storage device (i.e., the longitudinal direction), and the extension length is limited, that is, not equal to the entire axial direction of the hydrogen storage device, so that when heated after inserting the element, the tip end of which, which can also be called a heating end, is separated from the bottle mouth of the bottle body, so as not to prevent the bottle mouth of the hydrogen storage device from transferring the solid hydrogen storage material to the outside.

It is understood that the heating element mentioned above extends into the hydrogen storage device, but is not limited to extending into the interior of the hydrogen storage device. Conversely, in the case of an irregular shape of the hydrogen storage device, the heating element protrudes into the outer center of the bottle body, while in the case of a regular shape of the hydrogen storage device, the heating element can protrude into the interior of the bottle body. or the heating element may be partially deep. Towards the outer center of the bottle body, the other part extends into the inner part of the bottle body pers, and the heat is transferred to the solid hydrogen storage material after heat is generated by contact conduction or radiation conduction, thereby heating the solid hydrogen storage material.

In addition to the heating element, the hydrogen storage device also includes an electrical connection element which is electrically connected to the heating element and is exposed on the bottle body. The power source of the heating element comes from the electrical connection element, and the electrical connection element is connected to an external power supply. After power-on, the external power supply transmits electrical energy to the electrical connection element, and then the electrical connection element transmits electrical energy to the heating element. After the electrical power is generated , the electrical energy is converted into heat, thereby heating the solid-state hydrogen storage material and increasing the pressure of the solid-state hydrogen storage material in the hydrogen storage device.

In different embodiments, the heating elements are installed differently.

With reference to 15 In this embodiment, the heating element 130 does not extend into the inside of the bottle body 120, that is, the heating method of the heating element 130 for the solid hydrogen storage material is indirect conduction heating rather than direct contact heating. Here, the bottle body 120 is provided along its axial direction with a groove body 121, which may be formed such that the bottom of the bottle body 120 extends to the inside of the bottle body 120, but the bottle body 120 is kept in a closed state as a whole, and the Extension part is formed in an irregular shape in the groove body 121, therefore the groove body 121 and the inside of the bottle body 120 are separated by the jacket wall of the bottle body 120, so that the groove body 121 is separated from the inside of the bottle body 120 and the groove body 121 is further separated from the bottle body 120 is. outdoor connectivity.

After the tank body 121 is provided, the heater 130 penetrates into the tank body 121 and fits with the tank body 121 in a loose fit, that is, the outer surface of the heater 130 is in close contact with the inner wall of the tank body 121 and heat is in the Heating element 130 generated. After that, the heater 130 directly heats the bottle body 120, and then the bottle body 120 conducts heat to the solid hydrogen storage material. In this heating mode, the heating efficiency of the solid-state hydrogen storage material can be slowed down, but the heatable temperature of the solid-state hydrogen storage material can be more precisely controlled.

It is understood that the interaction between the heating element 130 and the tank body 121 is not limited to the clearance fit between each side of the heating element 130 and the interior of the tank body 121 . It may also be that the outer surface of the heating element 130 has the shape of a tooth or a wave shape. There is also a layer of air between the inner walls. The layer of air is both a thermal insulation layer and a conductive layer. The heat generated from the heater 130 can be conducted indirectly to the bottle body 120 through the air layer, and the total heat transfer of the heater 130 can also be quantitatively controlled.

Further, the heating end of the heating element 130 remote from the electric connecting element 140 is not in direct contact with the tank body 121. In contrast, the length of the tank body 121 along the axial direction of the bottle body 120 is greater than the length of the heating element 130 along the axial direction of the Bottle body 120. , so that there is a heating layer 122 between the heating end of the heating element 130 and the tank bottom of the tank body 121. The heating layer 122 similar to the above-mentioned air layer Excessive heating of the solid-state hydrogen storage material. That is, after the heating layer 122 is provided, it acts as both a conducting medium and a heat insulating medium, which slightly controls the heating efficiency of the heating element 130 for the solid hydrogen storage material.

By configuring the heat conduction path as a heating element 130 - bottle body 120 - solid hydrogen storage material, the heating process of the solid hydrogen storage material is made more stable and safer.

When installing the heater 130, the installation end of the heater 130 is male-threaded, and the slit of the tank body 121 is female-threaded; Optionally, the bottom of the bottle body 120 is flush with the notch of the tank body 121, so that the bottom of the bottle body 120 is flat, and when the hydrogen storage device 100 is placed, the bottom of the bottle B. schenkörpers 120 can be attached directly to the placement surface. Also, unlike the prior art form of the hydrogen storage device 100, it is more convenient to install. In order to prevent the hydrogen storage device 100 from falling over, at least one anti-slip groove 123 is opened on the lower end surface of the bottle body 110, and the opening direction of the anti-slip groove 123 is along the radial direction of the bottle body 1120 or at a predetermined angle with the radial direction of the bottle body 120 For example, the anti-slip grooves 123 are arranged obliquely or at a plurality of preset angles to generate frictional forces in different directions, thereby further enhancing the anti-slip effect.

With reference to 16 In this embodiment, the heating element 130 is in direct contact with the solid hydrogen storage material. Therefore, an opening 124 is provided in the bottle body 120 along the axial direction, and the opening 124 communicates with the inside space and the outside space of the bottle body 120. The heating element 130 can enter the inside of the bottle body 120 from the opening 124 and close the opening 124 to prevent the solid hydrogen storage material from overflowing. At the same time, the heating element 130 heats the solid-state hydrogen storage material after it is turned on.

Similarly, to achieve the sealing of port 124, the installation end of heating element 130 is externally threaded and port 124 is internally threaded;

In each of the above embodiments, the heating element 130 is a resistance wire with a built-in temperature sensor, or the temperature sensor is placed externally on the resistance wire to sense the temperature of the resistance wire, allowing the user to monitor the heating process of the heating element 130 in real time. On the other hand, the electrical connector 140 has a socket into which an external power source is plugged in to receive power.

A receiving step 135 is preferably or optionally provided where the bottle body 120 receives the electrical connection element 140, the radial width of the receiving step 125 being greater than the radial width of the heating element 130 and the heating element 130 being able to penetrate through the receiving step 125. , and the radial width of the electrical connection element 140 coincides with the receiving step 125, so that when the electrical connection element 140 is installed in contact with the receiving step 125, when the heating element 130 extends, the electrical connection element 140 is blocked by the receiving step 125, the Displacement that can reach the middle of the bottle body 120 is limited by the receiving step 125, and the electric connector 140 partially protrudes from the bottle body 120, which is convenient for the user to connect an external power source. In the above configuration, the receiving step 125 can be provided with an additional configuration for fixed connection with the electrical connection member 140, such as a snap type, a screw type, etc., to further stabilize the installation relationship between the heating element 130 and the bottle body 120 and prevent the internal solid state hydrogen storage. The problem of ejection of the heating element 130 after the material pressure is increased.

It goes without saying that in order to achieve consistency in the overall shape of the hydrogen storage device 100, the electrical connection element 140 must not protrude from the bottle body 120, for example it must be slightly recessed at the receiving step 125. or be flush with the adjustment level 115. If the electrical connector 140 is slightly recessed at the receiving step 125, an additional sealing end may be provided at the receiving step 125. When the electrical connector 140 is not connected to an external power source, the sealing end is sealed to the receiving step 125 to seal the electrical connector 140 to the receiving step 125 . The connector 140 is hidden inside and is only opened when needed.

Referring to FIG. 17, the safety device 200 preferably further comprises a valve body 220 located at the bottle mouth of the bottle body 120, the valve body 220 comprising: an air inlet valve 221 communicating with the bottle mouth and transmitting hydrogen into the bottle body 120; an inflation valve 222 communicating with the intake valve 221 receives hydrogen in one direction and transmits it to the intake valve 221; safety valve 223; Pressure control valve 224, controls the air pressure in the valve body 220, the outlet valve 225 communicates with the inlet valve 221, takes in hydrogen, is connected to a stack, and 15-50 kpa hydrogen is supplied to the stack, valve 226 is switched manually.

Having the hydrogen storage device mentioned above, it can be applied to a hydrogen energy moped. The hydrogen energy moped includes an engine and a stack connected to the engine, and the stack is further connected to the hydrogen storage device to receive the exhaust hydrogen to use the hydrogen pressure to generate electricity.

With reference to 23 In order to improve the hydrogen desorption efficiency of the low-pressure hydrogen storage device, a temperature control system for the hydrogen storage device is shown. The hydrogen storage device includes a bottle body and a valve body placed at the air outlet of the bottle body. After the solid hydrogen storage material in the hydrogen storage device is heated, the stack is pressurized to 15-50 kPa through the valve Body pressure regulator When not in use, the internal pressure of the hydrogen storage device is low (low-pressure Hydrogen storage in the general sense), which does not cause any harm to users, and the storage can be liquid hydrogen, hydrogen powder, etc. When it is necessary to use or improve the internal hydrogen release efficiency, the hydrogen storage device can be heated. To this end, the temperature control system also includes temperature monitoring equipment and heating equipment. The temperature monitoring equipment is installed in the hydrogen storage device. For example, it can be used with the hydrogen storage device. A temperature sensor is fixed at the same position as the pressure valve of the pressure monitoring device, which is used as a temperature monitoring device when the temperature monitoring device works. It monitors the temperature in the bottle body of the hydrogen storage device, that is, directly monitors the solid-state hydrogen storage device in real time .The temperature of the material, for the temperature of the solid-state hydrogen storage material, the temperature monitoring device generates a temperature signal carrying the current temperature information of the solid-state hydrogen storage material. On the other hand, the heating device can be placed in the hydrogen storage device or outside the hydrogen storage device, and directly or indirectly heat the solid hydrogen storage material when working, for example, when the heating device is placed outside the hydrogen storage device, the heat generated by the heating device is first transferred to the bottle body and becomes passed to the solid hydrogen storage material; when the heater is placed inside the bottle body, the heat generated by the heater is directly transmitted or radiated to the solid-state hydrogen storage material, thereby increasing the temperature of the solid-state hydrogen storage material. Due to the closed nature of the hydrogen storage device, with constant quality, the solid state hydrogen storage material will also increase in pressure, ie, from a low pressure state to a high pressure state.

Since the solid-state hydrogen storage material cannot be heated indefinitely, the temperature control system also includes a temperature control module that is electrically connected to the temperature monitoring device or the heating device, with the temperature signal being formed by the temperature monitor and sent to the temperature control module. A temperature threshold is pre-stored in the temperature control module, and the temperature threshold reflects the expected operating temperature of the hydrogen storage device or the temperature of the solid hydrogen storage material therein with the expected rate of hydrogen desorption. The temperature control module compares the current temperature to the temperature threshold. When the current temperature information transmitted by the temperature signal is lower than the temperature threshold, it means that the temperature of the low-pressure solid-state hydrogen storage material is low. and the hydrogen release rate at that time will not reach the threshold. When expected, the temperature control module generates an activation command and sends it to the heater. Based on the activation command, the heater starts to work and heat solid-state hydrogen storage material in the hydrogen storage device, and the temperature of the solid-state hydrogen storage material will rise. After it is high, it will increase its hydrogen release rate to meet the needs of normal use.

In a preferred embodiment, the temperature control module includes a temperature comparison circuit, a heater control circuit, and a heater protection circuit. In particular, the temperature comparison circuit is electrically connected to the temperature monitoring device, and the above-mentioned temperature threshold (which can be a specific value or data range) is stored therein, which receives the temperature signal and compares the current temperature with the temperature threshold; the heater control circuit compares the temperature with the circuit and the heater are electrically connected, and the comparison results of the temperature comparison circuit, such as. B. the current temperature is greater than the temperature threshold, the current temperature is equal to the temperature threshold, the current temperature is less than the temperature threshold, etc., are sent to the heater control circuit, based on different comparison results, produce different For example, when the current temperature is greater than the temperature threshold or the current temperature is equal to the temperature threshold, it means that the hydrogen desorption rate in the hydrogen storage device is sufficient, and when the current temperature is lower than the temperature threshold, the activation command is generated; the heating protection circuit is set in the heating control circuit. The operating status of the entire temperature control module is monitored for the heating.

Further, the temperature control module also includes a clock unit that is electrically connected to the heating control circuit and adds clock information to the activation instruction, the clock information including the heating time t; the heating time t is calculated based on the following formula: t = (temperature threshold - current temperature) × time threshold / temperature threshold difference, the temperature threshold difference and the time threshold are pre-stored based on a test temperature and a test time. In addition to the above heating time t, the heating time t can also be set to a fixed value, within the set heating time t, the activation of the heater is maintained, and the activation is terminated after the heating time t is over. A weight value can also be added in the calculation formula of the heating time t, and the weight value adjusts the heating time t according to the scene used (regional information, seasonal information, etc.) to adjust the heating time t at any time according to different usage conditions.

Preferably, even when the heating device is activated, the heating state is adjusted in real time, for example, after the heating time t, the monitoring result of the temperature monitoring device on the hydrogen storage device is updated Current If the temperature is still lower than the temperature threshold, the temperature control module generates an activation command again and sends the activation command to the Heater to control the heater and keep working. It is understood that if the current temperature is still lower than the temperature threshold when reheating, the above steps are repeated until the current temperature is higher than or equal to the temperature threshold, that is, if it is within the heating time t that current temperature during the heating process is higher than If the temperature threshold is set, it means that the heat provided by the heating process is sufficient, then the temperature control module calculates the difference between the current temperature and the temperature threshold, and compares the difference with a preset difference that is pre-stored in the temperature control module The difference between the current temperature and the temperature threshold is greater than the preset difference, and the shutdown command is sent to the heating device within the heating time t in advance. This means that the heating effect is fulfilled within the heating time t and not only fulfilled exactly, but if there is a certain redundancy, the heating process is terminated prematurely.

In a preferred embodiment, the temperature monitoring device is a temperature sensor which is fastened in the bottle body and connected to the valve body and which can be arranged together with the pressure sensor for monitoring the pressure in the hydrogen storage device. The heater is in the form of a band and is placed on the outside of the bottle body. Or in other preferred embodiments, the heater extends into the bottle body for heating the hydrogen storage device, while the temperature monitor is attached to the heater and is integrally formed with the heater (the heater itself is a heating component with a temperature monitor) or a temperature monitor is installed on the heater . The end of the heater is provided with a connector, the tempering module has an electrical connector, and the electrical connector is inserted into the connector to connect with the heater. By supplying electrical energy to the heating device, the heating device turns on the electrical energy into thermal energy. In another embodiment, the electrical connector further comprises a heat conducting element, and the waste heat of the temperature monitoring device is transferred to the heating device through the heat conducting element. The heat compensation mechanism can further save energy.

Preferably, the cell stack controller can also provide thermal energy to the temperature control system, ie the waste heat generated during operation of the fuel cell stack will offset the heat at the temperature monitoring device, thereby saving energy.
