DETAILED DESCRIPTION

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0033] The widespread adoption of electric vehicles and vehicles powered by low-carbon, renewable fuels like hydrogen, methanol, and ammonia will contribute to achieving peak carbon emissions and reducing carbon emissions in the transportation sector. Currently, electric vehicles are gaining market share year by year. However, due to limitations in battery technology, charging times for existing electric vehicles remain significantly longer than those of fuel-powered vehicles, while their range is lower. With limited access to charging stations, electric vehicle owners are prone to range anxiety, especially during peak charging periods. Electric vehicles often break down due to a lack of power during long journeys. Furthermore, during peak charging periods, expanding the capacity of existing charging stations is difficult, significantly impacting the power grid and leading to significantly longer charging times.

[0034] In related technologies, renewable fuel vehicles represented by hydrogen fuel cell vehicles can circumvent the problem of long charging time for electric vehicles. Among the many clean fuels, hydrogen is abundant in source, has high calorific value, and has zero carbon emissions, and is considered to be the most ideal clean energy. However, at this stage, the cost of hydrogen production is high, and storage and transportation are relatively difficult, which greatly limits the development of the hydrogen economy.

[0035] In response to the above technical problems, the technical concept of the present invention is to design a mobile charging vehicle using methanol and ammonia as raw materials, which can be used to supply electric vehicles with electricity, hydrogen and renewable fuels. The vehicle can be deployed off-grid at integrated energy supply stations operating during peak hours as a means of alleviating charging peaks. It can also be deployed in a distributed manner or used for roadside rescue.

[0036] Figure 1 This is a schematic diagram of the structure of a mobile charging vehicle based on renewable fuel provided by an embodiment of the present invention. Figure 1 As shown, the mobile energy charging vehicle 10 based on renewable fuel includes a transport vehicle 101, and a fuel storage tank 102, a direct fuel cell 103 and an external power supply system 104 arranged on the transport vehicle 101;

[0037] The fuel storage tank 102 is connected to the direct fuel cell 103 for providing renewable fuel to the direct fuel cell 103; the direct fuel cell 103 is connected to the external power supply system 104 for providing the first electrical energy to the external power supply system 104; the external power supply system 104 provides an external charging terminal for charging the connected charging device.

[0038] Specifically, the fuel storage tank 102 stores renewable fuel, such as methanol, ammonia, etc., and one port of the fuel storage tank 102 is connected to the direct fuel cell 103 for delivering renewable fuel thereto; the direct fuel cell 103 generates electricity using renewable fuel and supplies the generated electricity to the external power supply system 104; the external power supply system 104 can be understood as a charging pile with a charging end. When a charging device such as an electric car needs to be charged, it can be connected to the charging end to achieve charging.

[0039] In some embodiments, the transport vehicle 101 is further equipped with a fuel filling system 105; the fuel filling system 105 is connected to the fuel storage tank 102 and is used to provide renewable fuel to the fuel cell device. Specifically, in addition to providing external power, the mobile charging vehicle 10 can also supply fuel to the user's fuel cell vehicle through the fuel filling system 105, thus achieving simultaneous fuel and power supply, allowing the user to choose to charge or recharge according to their needs.

[0040] In some embodiments, the fuel filling system 105 is further configured to extract renewable fuel from a charging station 20 and inject it into the fuel storage tank 102. Specifically, when the renewable fuel content in the fuel storage tank 102 is low, the mobile charging vehicle 10 can move to a nearby charging station 20, extract renewable fuel from the charging station 20 via the fuel filling system 105, and inject the fuel into the fuel storage tank 102.

[0041] In some embodiments, the renewable fuel is one of alcohol and ammonia; the alcohol includes at least one of the following: methanol and ethanol; the ammonia includes at least one of the following: liquid ammonia and ammonia gas.

[0042] Specifically, the renewable fuel selected in the embodiment of the present invention is methanol or ammonia for the following reasons: First, compared with batteries, methanol and ammonia have a larger volume density. For example, the volume energy density of methanol reaches 4300Wh / L, and the volume energy density of liquid ammonia can reach 3778Wh / L, which is much higher than the energy density of less than 400Wh / L of existing lithium-ion batteries. Therefore, the fuel storage tank 102 can be small in size and occupy a small area; second, compared with hydrogen, the production cost of hydrogen is high, and the storage and transportation are relatively difficult. Methanol and ammonia are easier to transport and store, and are better clean energy carriers; finally, clean fuels such as methanol and ammonia can be produced from hydrogen. For example, methanol can be obtained by reacting hydrogen and carbon dioxide, and ammonia can be produced from hydrogen and nitrogen, which is environmentally friendly.

[0043] In some embodiments, when the renewable fuel is methanol, the direct fuel cell 103 is a methanol fuel cell; the methanol fuel cell includes at least one of the following: an alkaline methanol fuel cell, a proton exchange membrane methanol fuel cell, a phosphate methanol fuel cell, and a solid oxide methanol fuel cell.

[0044] Specifically, when the renewable fuel in the fuel storage tank 102 is methanol, a direct methanol fuel cell is used. In the direct methanol fuel cell, the power generation process is as follows:

[0045] Anode: CH3OH+H2O→CO2+6H + +6e -

[0046] Cathode: O2+4e - +4H + →2H2O

[0047] The methanol fuel cells used include, but are not limited to, alkaline methanol fuel cells, proton exchange membrane methanol fuel cells, phosphate methanol fuel cells, and solid oxide methanol fuel cells.

[0048] In some embodiments, when the renewable fuel is ammonia, the direct fuel cell 103 is an ammonia fuel cell; the ammonia fuel cell includes at least one of the following: an alkaline ammonia fuel cell, a proton exchange membrane ammonia fuel cell, a phosphate ammonia fuel cell, and a solid oxide ammonia fuel cell.

[0049] Specifically, when the renewable fuel in the fuel storage tank 102 is ammonia, a direct ammonia fuel cell is used. In the direct ammonia fuel cell, the power generation process is as follows:

[0050] Anode: 2NH3→N2+6H + +6e -

[0051] Cathode: O2+4e - +4H + →2H2O

[0052] The ammonia fuel cells used include, but are not limited to, alkaline ammonia fuel cells, proton exchange membrane ammonia fuel cells, phosphate ammonia fuel cells, and solid oxide ammonia fuel cells.

[0053] The renewable fuel-based mobile charging vehicle provided in this embodiment includes a transport vehicle, and a fuel storage tank, a direct fuel cell and an external power supply system arranged on the transport vehicle; the fuel storage tank is connected to the direct fuel cell for providing renewable fuel to the direct fuel cell; the direct fuel cell is connected to the external power supply system for providing a first electric energy to the external power supply system; the external power supply system provides an external charging terminal for charging a connected charging device; the designed mobile charging vehicle is flexible and can be externally charged and refueled without being restricted by the power grid and the charging mother station; the charging efficiency is high and it is environmentally friendly; the entire system is relatively compact and occupies a small area; the initial investment cost and operating cost are reduced, especially meeting the charging needs during peak charging periods.

[0054] Based on the above embodiments, Figure 2 A schematic diagram of the structure of another mobile charging vehicle based on renewable fuel provided by an embodiment of the present invention is shown in FIG. Figure 2 As shown, the transport vehicle 101 is also provided with a reforming hydrogen production device 106 and a hydrogen fuel cell 107; the reforming hydrogen production device 106 is connected to the fuel storage tank 102, and is used to produce hydrogen based on the obtained renewable fuel; the hydrogen fuel cell 107 is connected to the reforming hydrogen production device 106, and is used to generate a second electrical energy based on the obtained hydrogen; the hydrogen fuel cell 107 is connected to the external power supply system 104, and is used to provide the second electrical energy to the external power supply system 104.

[0055] Specifically, the mobile charging vehicle 10 provided in this embodiment is based on the fuel supply and power generation system of the aforementioned embodiment, and further adds an on-board reforming hydrogen production device 106. The renewable fuel in the fuel storage tank 102 is first reformed into hydrogen by the reforming hydrogen production device 106, and then supplied to the hydrogen fuel cell 107 to generate electricity, so that the charging equipment such as electric vehicles can be powered through the external power supply system 104.

[0056] In some embodiments, when the renewable fuel is methanol, the reforming hydrogen production device 106 performs a hydrogen production reaction based on the methanol and condensed water, and the condensed water comes from the hydrogen fuel cell 107 .

[0057] Specifically, for the mobile charging vehicle 10 storing methanol, the chemical reactions occurring in the reforming hydrogen production device 106 are as follows:

[0058] CH3OH+H2O→CO2+3H2

[0059] The required water comes from the condensed water generated by the hydrogen fuel cell 107 .

[0060] For the mobile charging vehicle 10 storing ammonia, the chemical reactions occurring in the reforming hydrogen production device 106 are as follows:

[0061] 2NH3→N2+H2.

[0062] In some embodiments, the transport vehicle 101 is further provided with an external hydrogenation system 108 ; the external hydrogenation system 108 is connected to the reforming hydrogen production device 106 to provide hydrogen to the hydrogen fuel device.

[0063] Specifically, the reforming hydrogen production device 106 is further added with an external hydrogenation system 108. The external hydrogenation system 108 can be understood as a hydrogenation machine for supplying hydrogen to the outside. Therefore, the mobile charging vehicle 10 designed in this embodiment can simultaneously supply electric vehicles, vehicles using the corresponding fuel in the fuel storage tank 102, and hydrogen fuel cell vehicles. Users can charge, refuel or add hydrogen according to their own needs.

[0064] In some embodiments, the transport vehicle 101 is also provided with a control system; the control system is used to receive charging information input by the user through a human-computer interaction interface, and control the direct fuel cell 103 or hydrogen fuel cell 107 to provide electrical energy to the external power supply system 104 according to the charging information.

[0065] Specifically, when an electric vehicle needs to be charged, the user can connect the electric vehicle to the charging terminal of the external power supply system 104, and can input charging information, such as charging time, charging speed, etc., through the human-computer interaction interface; after the control system receives the charging information, it will control the direct fuel cell 103 or the hydrogen fuel cell 107 to supply power to the external power supply system 104, that is, the direct fuel cell 103 obtains renewable fuel from the fuel storage tank 102 to generate electricity, or the reforming hydrogen production device 106 obtains renewable fuel from the fuel storage tank 102 to generate hydrogen, and transports the hydrogen to the hydrogen fuel cell 107, and the hydrogen fuel cell 107 generates electricity.

[0066] In some embodiments, the control system is specifically used for at least one of the following: under a first operating condition, controlling the direct fuel cell 103 to provide the first electrical energy to the external power supply system 104; under a second operating condition, controlling the hydrogen fuel cell 107 to provide the second electrical energy to the external power supply system 104; under a third operating condition, controlling the direct fuel cell 103 and the hydrogen fuel cell 107 to simultaneously provide the first electrical energy and the second electrical energy to the external power supply system 104.

[0067] Specifically, during the charging off-season, one of the direct fuel cell 103 and the hydrogen fuel cell 107 can be controlled to supply power to the external power supply system 104; during the charging peak period, the direct fuel cell 103 and the hydrogen fuel cell 107 can be controlled to supply power to the external power supply system 104 at the same time.

[0068] In some embodiments, the control system is further used to: receive first charging information input by the user through the human-computer interaction interface, and control the fuel filling system 105 to extract renewable fuel from the fuel storage tank 102 and inject it into the fuel cell device according to the first charging information.

[0069] Specifically, when a renewable fuel cell vehicle needs to be refueled, it can be connected to the fuel filling system 105 and information such as the fuel filling amount and filling speed can be input into the human-computer interaction interface. The control system controls the fuel filling system 105 based on the input information to extract fuel from the fuel storage tank 102 and fill it into the fuel cell vehicle.

[0070] In some embodiments, the control system is also used to: receive second charging information input by the user through the human-computer interaction interface, and control the external hydrogenation system 108 to extract hydrogen from the reforming hydrogen production device 106 and inject it into the hydrogen fuel cell equipment according to the second charging information.

[0071] Specifically, when a hydrogen fuel cell vehicle needs to be refilled with hydrogen, it can be connected to the external hydrogenation system 108, and the hydrogenation amount, hydrogenation speed and other information can be input into the human-computer interaction interface. The control system extracts hydrogen from the reforming hydrogen production device 106 and injects it into the hydrogen fuel cell vehicle based on the received hydrogenation information.

The control system may also, under a second operating condition, open K2 and close K1, K3, and K4, so that the hydrogen fuel cell 107 supplies power to the external power supply system 104. The control system may also, under a third operating condition, open K1 and K2 and close K3 and K4, so that both the direct fuel cell 103 and the hydrogen fuel cell 107 supply power to the external power supply system 104 simultaneously. When fuel filling is required, the control system can control K4 to open and K1, K2, and K3 to close, so that the fuel filling system 105 extracts fuel from the fuel storage tank 102. When hydrogenation is required, the control system can control K2 and K3 to open and K1 and K4 to close, so that the reforming hydrogen production device 106 extracts fuel from the fuel storage tank 102 to produce hydrogen, and injects hydrogen through the external hydrogenation system 108.

[0073] In some embodiments, the control system is further configured to detect a current content of the renewable fuel in the fuel storage tank 102 and output an alarm message when the current content is lower than a preset threshold.
