[0024] To more clearly illustrate the technical solution of the present invention, the accompanying drawings used in the description of the present invention will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0025] Figure 1 This is a schematic diagram of the structure of a thermally driven electric vehicle according to an embodiment of the present invention;

[0026] Figure 2 This is a flowchart of the steps of a thermal storage driving method provided in an embodiment of the present invention. Detailed Implementation

[0027] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] Reference Figure 1 The diagram shows a schematic of the structure of a thermally driven electric vehicle according to an embodiment of the present invention. The electric vehicle includes: one or more first energy storage devices 101, a thermoelectric conversion module 102, a pneumatic conveying device 103, and a temperature control module. The pneumatic conveying device includes a circulation pipe and a conveying pump on the circulation pipe. The conveying pump is connected to the inlet of the first energy storage device through the circulation pipe to deliver a fluid working medium to the first energy storage device. The first energy storage device is filled with a first energy storage medium, and the first energy storage medium can withstand a temperature range of -250°C to 3000°C. The outlet of the first energy storage device is connected to the thermoelectric conversion module through the circulation pipe. The thermoelectric conversion module includes a compressor and a steam turbine generator.

[0029] In practical applications, the first energy storage device can store thermal energy up to 3000℃, with a high thermal density. Consequently, the first energy storage device can convert the stored thermal energy into electrical energy to continuously power electric vehicles, thereby improving the range of electric vehicles.

[0030] In this embodiment of the invention, when the first energy storage device stores thermal energy up to 3000°C, in order to realize the conversion between thermal energy and electrical energy, the thermoelectric conversion module, the pneumatic conveying device, and the temperature control module can all be adaptively adjusted according to the scenario. For example, the pipes in the pneumatic conveying device and the thermoelectric conversion module are made of high-temperature resistant materials, and the temperature range that the temperature control module can measure must include the highest and lowest temperatures in the scenario.

[0031] In this embodiment of the invention, the first energy storage medium can be selected from energy storage particles with high temperature resistance and high specific heat capacity, such as graphite particles. Graphite particles refer to tiny particles made of graphite material. Graphite is a mineral composed of carbon elements, with a layered crystal structure. The carbon atoms in each layer are bonded by strong covalent bonds, while the layers interact with each other through relatively weak van der Waals forces. Graphite particles also have excellent thermal conductivity, enabling them to effectively transfer heat. Furthermore, graphite exhibits good stability against most chemical substances at room temperature. Simultaneously, graphite can maintain the stability of its physical and chemical properties at high temperatures; the melting point of graphite is approximately 3652 degrees Celsius (6602 degrees Fahrenheit).

[0032] It should be noted that the specific material of the first energy storage medium in the embodiments of the present invention can be selected according to the actual application scenario, and is not limited to the graphite particles in the above example. No further restrictions are imposed on this in the embodiments of the present invention.

[0033] In one embodiment of the present invention, the first energy storage device is detachably connected to an electric vehicle. Specifically, the first energy storage device can be fixed in a specific first energy storage device clip slot; the first energy storage device can be replaced at any time, and the operation is simple.

[0034] In another embodiment of the present invention, the heat stored in the first energy storage device may be derived from: solar energy, wind energy, off-peak electricity, refrigeration equipment, industrial waste heat, geothermal energy, biomass energy, electrical energy conversion, environmental thermal energy, chemical reaction heat, nuclear energy, wind energy, and tidal energy.

[0035] Solar thermal energy can be collected by solar collectors and stored in thermal energy storage systems, such as hot water storage tanks or phase change materials. Industrial waste heat, generated during industrial production processes such as steel, chemical, and power industries, can be recovered and stored through heat exchangers. Geothermal energy can be extracted through geothermal wells and stored in geothermal energy storage systems for heating or power generation. Heat generated during biomass combustion or biomass pyrolysis can be stored for heating or power generation. Electrical energy can be converted into heat or cold energy for storage through methods such as resistance heating, electrochemical reactions, or water electrolysis. Environmental thermal energy, such as heat from the air, water, or soil, can be extracted and stored using heat pump technology. Chemical reaction heat is the heat released during certain chemical reactions, such as the heat generated by the reaction of sodium hydroxide with water. Heat generated in nuclear reactors can be used to produce steam, which drives turbines to generate electricity, and excess heat can be stored. Wind and tidal energy: Excess electricity generated during the power generation of these renewable energy sources can be converted into thermal energy for storage through electrothermal conversion equipment.

[0036] In one embodiment of the present invention, in order to store and release more heat, multiple first energy storage devices may be used in the electric vehicle, and the multiple first energy storage devices may be connected in series or in parallel.

[0037] In this embodiment of the invention, the functions of each module in the electric vehicle are as follows:

[0038] The pneumatic conveying device in this embodiment of the invention can be used to provide a fluid working medium to a first energy storage device; wherein the fluid working medium can be air or an inert gas. Furthermore, the pneumatic conveying device in this embodiment of the invention can adjust the gas flow rate entering the first energy storage device, thereby controlling the conversion rate of thermal energy to electrical energy.

[0039] In one embodiment of the present invention, the gas delivery device further includes a filter. The filter is used to filter the delivered gas, such as removing particles or other substances carried in the gas that may affect the conversion of heat energy to electrical energy in this embodiment of the invention.

[0040] In this embodiment of the invention, the first energy storage device can store heat through a first energy storage medium and exchange heat with an introduced fluid working medium. By selecting a first energy storage medium with high temperature resistance and high specific heat capacity, the first energy storage device ensures sufficient contact between the fluid working medium and the first energy storage medium after the fluid working medium, which is at a lower temperature, thus achieving heat transfer. Specifically, heat energy can be transferred from the first energy storage medium to the fluid working medium. Subsequently, the heat energy is released as the fluid working medium flows out of the first energy storage device.

[0041] The thermoelectric conversion module in this embodiment of the invention can be used to receive the heated fluid working medium from the first energy storage device, pressurize the fluid working medium using a compressor, and convert the heat of the pressurized fluid working medium into electrical energy using a steam turbine generator to power electric vehicles. The electric vehicles in this embodiment of the invention can be electric vehicles.

[0042] The temperature control module in this embodiment of the invention can be used to monitor the operating status of electric vehicles and control the first energy storage device to start or stop energy release according to the operating status.

[0043] Specifically, a first valve is installed on the circulation pipeline before the inlet of the first energy storage device, and a second valve is installed on the circulation pipeline after the outlet of the first energy storage device. The temperature control module controls the opening or closing of the first and second valves to control the first energy storage device to start or stop releasing energy.

[0044] In practical applications, the temperature control module can control the opening and closing of the first and second valves. In scenarios where the first energy storage device needs to release heat, the temperature control module can open the first and second valves, allowing the first energy storage device to exchange heat with a working fluid and output the heated working fluid, thus releasing heat. In scenarios where the first energy storage device does not need to release energy, the temperature control system can close the first and second valves, keeping the first energy storage device in a static environment and preventing it from releasing energy.

[0045] In this embodiment of the invention, the status information of the electric vehicle includes battery status information; the temperature control system can monitor the battery status information and then control the first valve and the second valve based on the battery status information. Specifically, when the battery status information of the electric vehicle indicates that the remaining charge is less than a first preset charge, the temperature control module can control the opening of the first valve and the second valve to control the first energy storage device to release energy; when the battery status information of the electric vehicle indicates that the remaining charge is greater than or equal to a second preset charge, the temperature control module can control the closing of the first valve and the second valve to control the first energy storage device to stop releasing energy.

[0046] In one embodiment of the present invention, the electric vehicle further includes a central control system. The central control system may include a central control interface for displaying the real-time status of the vehicle. The temperature control module includes a first temperature meter (e.g., [missing information]) connected to the top of the first energy storage device. Figure 1 T1 in the first energy storage device and a second temperature controller (such as T1) connected to the top of the first energy storage device. Figure 1 T2); where the top of the first energy storage device is the fluid working medium outlet with the lowest temperature, and the bottom of the first energy storage device is the fluid working medium inlet with the highest temperature.

[0047] The central control system generates a first alert message indicating that the first energy storage device is running out of energy when the second temperature controller detects that the temperature of the first energy storage device is lower than a first set value. This first alert message is then displayed on the central control interface of the central control system. For example, the first alert message could read, "The first energy storage device is about to run out of energy; please recharge." When the temperature control module detects that the temperature of the first energy storage device is lower than the first set value, it controls the first energy storage device to stop releasing energy.

[0048] The central control system is also used during the charging phase of the first energy storage device. When the first temperature gauge detects that the temperature is higher than the second set value, it generates a second reminder message to indicate that the first energy storage device is fully charged, and displays the second reminder message on the central control interface of the central control system. For example, the second reminder message could be "The first energy storage device is fully charged, please unplug it." At the same time, the external charging circuit is disconnected to avoid overcharging.

[0049] It should be noted that the first and second set values ​​in the embodiments of the present invention can be set according to the actual scenario, and no restrictions are imposed on them in the embodiments of the present invention.

[0050] The temperature control system is used to control the first energy storage device to shut off energy release when it detects that the first energy storage device is in the charging stage, and to control the first energy storage device to start energy release when it receives a command from the central control system to control the first energy storage device to start energy release.

[0051] In one embodiment of the present invention, a first energy storage device is charged in an energy storage system. The energy storage system includes a fluidized bed charging module, a fixed bed energy storage module, and a circulation pipe connecting the fluidized bed charging module and the fixed bed energy storage module. The fixed bed energy storage module includes a first fixed bed group consisting of multiple fixed beds connected in series or in parallel, a second fixed bed connected in series with the first fixed bed group, a third thermometer located at the top of the second fixed bed, and a fourth thermometer located at the bottom of the second fixed bed. A fluid working medium is circulated in the circulation pipe. The fluidized bed cavity of the fluidized bed charging module is filled with a second first energy storage medium, and the fixed bed cavity of the fixed bed energy storage module is filled with a first energy storage medium. The first energy storage device is a fixed bed in the first fixed bed group.

[0052] In practical applications, the fluidized bed energy charging module heats the incoming fluid working medium, which then exchanges energy with the first energy storage medium. The fluid working medium carries the energy to the fixed bed energy storage module, where it stores energy in the fixed beds within the first fixed bed group before outputting it from the second fixed bed. This configuration allows the fixed beds in the first fixed bed group to be fully charged, and the charged fixed beds can then be disassembled for later use. Specifically, the charged fixed beds can be used in the electric vehicles described in this embodiment of the invention as the first energy storage device for energy release.

[0053] In one embodiment of the present invention, the thermal energy carried by the fluid working fluid is used to generate electricity at the thermoelectric conversion module. The generated electricity powers the vehicles. After thermoelectric conversion, the fluid working fluid has a lower temperature and can be directly discharged or recycled. When it is necessary to recycle the fluid working fluid, a circulation pipeline can be set between the thermoelectric conversion module and the delivery pump. The thermoelectric converted fluid working fluid is transported to the delivery pump through the circulation pipeline, and then the delivery pump inputs the fluid working fluid back into the first energy storage device for thermal energy conversion.

[0054] In one embodiment of the present invention, the electric vehicle includes: a second energy storage device, which is filled with a second energy storage medium. The second energy storage device is located between a first energy storage device and a thermoelectric conversion module. The second energy storage device uses the second energy storage medium and exchanges energy with the fluid working medium output from the first energy storage medium, thereby enabling the second energy storage medium to store energy. In this embodiment of the present invention, the second energy storage device can be used as an intermediate energy storage device between the first energy storage device and the thermoelectric conversion module to effectively control the temperature of the fluid working medium entering the thermoelectric conversion module. The second energy storage medium can withstand a temperature range of -250°C to 3000°C.

[0055] In one embodiment of the present invention, the temperature control module is also used to monitor the interior temperature of the electric vehicle and adjust the air intake speed of the pneumatic conveying device based on the interior temperature and the preset temperature of the vehicle heating system. The first outlet of the second energy storage device is connected to the thermoelectric conversion module, and the second outlet of the second energy storage device is connected to the fresh air device of the temperature control module. The fresh air device is used to cool the gas output from the second outlet of the second energy storage device to the preset temperature of the vehicle heating system.

[0056] That is, the second energy storage device, acting as an intermediate energy storage device, stores the heat carried by the fluid working medium flowing through it, thereby cooling the fluid working medium. Some of the heat is retained within the second energy storage device. The cooled fluid working medium, after passing through the second energy storage device, can then be transported to the thermoelectric conversion module through the first outlet. The second energy storage device can also provide heating for electric vehicles. Specifically, a fluid working medium can be supplied into the second energy storage device, where it exchanges heat with the device, transferring the heat energy from the second energy storage device to the fluid working medium, thus heating it. The heated fluid working medium is then transported from the second outlet to the fresh air system, providing vehicle heating.

[0057] In one embodiment of the present invention, in order to avoid energy waste, the outlet of the thermoelectric conversion module can be connected to the inlet of the pneumatic conveying equipment through a circulation pipe, so as to return the fluid working medium output from the thermoelectric conversion module to the pneumatic conveying equipment, realize the circulation of the fluid working medium of the entire system, and improve the thermal energy utilization rate.

[0058] In another embodiment of the invention, a third energy storage device may be installed on the circulation pipeline between the inlet of the pneumatic conveying device and the outlet of the thermoelectric conversion module. The third energy storage device is filled with a third energy storage medium, wherein the second energy storage medium can withstand a temperature range of -250°C to 3000°C. The third energy storage device is used to receive the fluid working medium output by the thermoelectric conversion module and to exchange heat with the fluid working medium using the third energy storage medium.

[0059] In this embodiment of the invention, the first energy storage device can be used as a backup energy source to convert thermal energy into electrical energy to power electric vehicles, thereby extending the driving range of electric vehicles. At the same time, the energy storage temperature of the first energy storage device is as high as 3000℃ and the energy storage density is large, which can release more energy for electric vehicles.

[0060] Reference Figure 2This diagram illustrates a flowchart of the steps of a thermal storage drive method for an electric vehicle according to an embodiment of the present invention. The method is applied to a thermally driven electric vehicle, which includes: one or more first energy storage devices, a thermoelectric conversion module, a pneumatic conveying device, and a temperature control module. The pneumatic conveying device includes a circulation pipe and a delivery pump on the circulation pipe. The delivery pump is connected to the inlet of the first energy storage device through the circulation pipe to deliver a fluid working medium to the first energy storage device. The first energy storage device is filled with a first energy storage medium, and the first energy storage medium can withstand a temperature range of -250°C to 3000°C. The outlet of the first energy storage device is connected to the thermoelectric conversion module through the circulation pipe. The thermoelectric conversion module includes a compressor and a steam turbine generator.

[0061] Pneumatic conveying equipment is used to provide the working fluid for the first energy storage device;

[0062] The first energy storage device is used to store heat through a first energy storage medium and to exchange heat with the introduced fluid working medium using the first energy storage medium.

[0063] The thermoelectric conversion module is used to receive the heated fluid working medium, pressurize the fluid working medium with a compressor, and convert the heat of the pressurized fluid working medium into electrical energy to power electric vehicles.

[0064] The temperature control module is used to monitor the operating status of electric vehicles and control the first energy storage device to start or stop energy release according to the operating status.

[0065] The thermal storage drive method based on this electric vehicle may specifically include the following steps:

[0066] Step S201: After the first energy storage device is turned on, the first energy storage medium filled in the first energy storage device is used to heat the fluid working medium input into the first energy storage device.

[0067] In practical applications, this first energy storage device can store thermal energy up to 3000℃, with a high thermal density, thus allowing it to release more heat.

[0068] After the first energy storage device is turned on, the fluid working medium is introduced into the first energy storage device from the bottom through a delivery pump. Inside the first energy storage device, heat energy exchange occurs between the high-temperature first energy storage medium that stores heat and the low-temperature fluid working medium. That is, the low-temperature fluid working medium is heated to a high-temperature fluid working medium, and then the heated fluid working medium is output from the top of the first energy storage device.

[0069] Step S202: After pressurizing the heated fluid working medium, a steam turbine generator is used to convert the heat of the pressurized fluid working medium into electrical energy.

[0070] After being heated, the working fluid is output from the top of the first energy storage device and can be transported to the compressor through a circulation pipeline. The gas is then compressed in the compressor and delivered to the steam turbine generator, which can then use the heat of the working fluid to convert it into electrical energy.

[0071] Step S203: Use electric power to drive electric vehicles.

[0072] In this embodiment of the invention, the electric vehicle also includes a central control system, and the temperature control module includes a first temperature instrument connected to the top of the first energy storage device and a second temperature controller connected to the top of the first energy storage device.

[0073] When the second temperature controller detects that the temperature of the first energy storage device is lower than the first set value, it generates a first reminder message to indicate that the first energy storage device has run out of energy, and displays the first reminder message on the central control interface of the central control system.

[0074] During the charging phase of the first energy storage device, when the first temperature instrument detects that the temperature is higher than the second set value, it generates a second reminder message to indicate that the first energy storage device is fully charged, and displays the second reminder message on the central control interface of the central control system.

[0075] When the first energy storage device is detected to be in the charging stage, the first energy storage device is controlled to shut off energy release. When a command is received from the central control system to control the first energy storage device to start energy release, the first energy storage device is controlled to start energy release.

[0076] Specifically, a first valve is installed on the circulation pipe before the inlet of the first energy storage device, and a second valve is installed on the circulation pipe after the outlet of the first energy storage device. The temperature control module controls the opening or closing of the first and second valves to control the energy release of the first energy storage device. That is, when the first and second valves are closed, the first energy storage device stops releasing energy; when the first and second valves are open, the first energy storage device starts releasing energy.

[0077] Specifically, when the battery status information of the electric vehicle is detected to be less than the first preset power level, the first valve and the second valve are opened to control the first energy storage device to release energy. When the battery status information of the electric vehicle is detected to be greater than or equal to the second preset power level, the first valve and the second valve are closed to control the first energy storage device to stop releasing energy.

[0078] In this embodiment of the invention, after the first energy storage device is turned on, the first energy storage medium filled in the first energy storage device heats the fluid working medium input into the first energy storage device; after the heated fluid working medium is pressurized, a steam turbine generator is used to convert the heat of the pressurized fluid working medium into electrical energy; the electric energy is used to drive the electric vehicle, thereby enabling the first energy storage device to serve as a backup energy source, converting heat energy into electrical energy to power the electric vehicle, extending the range of the electric vehicle. At the same time, the energy storage temperature of the first energy storage device is as high as 3000℃, and the energy storage density is large, which can release more energy for the electric vehicle.
