[0036] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Reference Figure 1a , showing a schematic structural diagram of a cooling and heating system for an electric transportation vehicle provided by an embodiment of the present invention; the cooling and heating system comprises: one or more first energy storage devices 101, one or more second energy storage devices 102, a pneumatic conveying device 104 and a temperature control module, the pneumatic conveying device 104 comprises a circulation pipeline and a delivery pump on the circulation pipeline, the first energy storage device 101 is connected to the second energy storage device 102 through a circulation pipeline, the second energy storage device 102 is connected to the air supply module of the electric transportation vehicle 103 through a circulation pipeline, the first energy storage device is filled with a first energy storage medium, the second energy storage device is filled with a second energy storage medium, the temperature range of the first energy storage medium and the second energy storage medium is -250°C to 3000°C, the inlet of the first energy storage device is connected to the delivery pump through a circulation pipeline, the outlet of the first energy storage device is connected to the inlet of the second energy storage device through the circulation pipeline, and the outlet of the second energy storage device is connected to the electric transportation vehicle through the circulation pipeline.

[0038] Among them, when the first energy storage device stores heat energy, the first energy storage medium and the second energy storage medium are high temperature resistant and high specific heat capacity media, so as to facilitate the storage of heat energy and can quickly exchange heat with the fluid working medium. In an embodiment of the present invention, the first energy storage medium and the second energy storage medium can withstand temperatures up to 3000 degrees Celsius; when the first energy storage device stores cold energy, the first energy storage medium and the second energy storage medium can withstand low temperatures. In an embodiment of the present invention, the first energy storage medium and the second energy storage medium can withstand low temperatures of -250°C.

[0039] The specific materials of the first energy storage medium and the second energy storage medium in the embodiment of the present invention can be selected according to the actual application scenario, and there is no excessive restriction on this in the embodiment of the present invention.

[0040] In the embodiment of the present invention, the second energy storage device is a buffer device between the first energy storage device and the electric transportation vehicle. The temperature range in the first energy storage device can be between -250°C and 3000°C, so that the first energy storage device can store a large amount of heat energy or cold energy, and the second energy storage device acts as a buffer device to adjust the temperature of the heat energy released by the first energy storage device, so that the appropriate temperature can be finally delivered to the electric transportation vehicle, thereby realizing cooling and heating at the vehicle end without starting the air conditioner.

[0041] It should be noted that in the embodiment of the present invention, in order to ensure that the energy of -250°C to 3000°C of the first energy storage device can be used, the materials of each component in the cooling and heating system also need to be selected to be applicable to this temperature range.

[0042] In one embodiment of the present invention, the first energy storage device is detachably connected to the electric transportation vehicle, so that it can be easily disassembled and replaced when the energy is exhausted.

[0043] In another embodiment of the present invention, the heat or cold stored in the first energy storage device may come from: solar energy, wind energy, valley electricity, refrigerators, industrial waste heat, geothermal energy, biomass energy, electricity conversion, environmental thermal energy, chemical reaction heat, nuclear energy, wind energy and tidal energy.

[0044] Among them, 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 is waste heat generated during industrial production, such as steel, chemical, and electric power industries, which 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 energy generated during biomass combustion or biomass pyrolysis can be stored for heating or power generation. Electric energy conversion can be converted into heat energy or cold energy for storage through resistance heating, electrochemical reactions, or electrolysis of water. Environmental thermal energy is heat energy in the environment, such as heat energy in air, water, or soil, which can be extracted and stored through heat pump technology. Cold energy can be generated by refrigerators or heat pump systems and stored in low-temperature storage equipment, such as ice storage systems. Chemical reaction heat is the heat released during certain chemical reactions, such as the heat generated by the reaction of sodium hydroxide and water. The heat generated in nuclear reactors can be used to generate steam, which in turn drives turbines to generate electricity and stores excess heat. Wind and tidal energy: The excess electricity generated by these renewable energy sources during the power generation process can be converted into thermal energy storage through electric-to-thermal conversion equipment.

[0045] In one embodiment of the present invention, the plurality of first energy storage devices are connected in series or in parallel, and the plurality of second energy storage devices are connected in series or in parallel.

[0046] In an embodiment of the present invention, the pneumatic conveying device is used to provide a fluid medium for the cooling and heating system. The fluid medium is air. The pneumatic conveying device in the embodiment of the present invention can control the speed of air supply, thereby controlling the temperature and wind speed of the fluid medium delivered to the electric transportation vehicle.

[0047] In an embodiment of the present invention, the first energy storage device is used to store heat or cold through the first energy storage medium, and uses the first energy storage medium to exchange energy with an introduced fluid medium.

[0048] When the first energy storage device stores heat, when a fluid medium is introduced into the first energy storage device, the temperature of the fluid medium is much lower than the first energy storage medium in the first energy storage device, so that the first energy storage medium can transfer the temperature to the fluid medium, and the fluid medium carries the heat out of the first energy storage device. In this stage, the heat is transferred from the first energy storage device to the fluid medium.

[0049] When the first energy storage device stores cold energy, when a fluid working medium is introduced into the first energy storage device, the temperature of the first energy storage medium in the first energy storage device is much lower than that of the fluid working medium. When the fluid working medium flows into the first energy storage device, the first energy storage medium contacts the fluid working medium, so that the cold energy is transferred from the first energy storage medium to the fluid working medium.

[0050] In an embodiment of the present invention, the second energy storage device can be used to receive the heated fluid medium delivered by the first energy storage device, and use the second energy storage medium to exchange energy with the fluid medium, so that the high-temperature fluid medium transfers heat to the low-temperature first energy storage medium for storage. The temperature of the fluid medium drops, and the fluid medium is delivered to the electric transportation vehicle to provide cooling or heating for the electric transportation vehicle.

[0051] In an embodiment of the present invention, a temperature control module may be further provided in the cooling and heating system, and the temperature control module may be used to monitor the operating state of the electric transportation vehicle and control the first energy storage device to start or stop energy release according to the operating state.

[0052] The operating status of the electric vehicle may include the status of the cooling and heating system in the electric vehicle, the startup status of the vehicle-mounted heating system, etc.

[0053] Specifically, when it is monitored that the operating state of the electric vehicle is to start the on-board heating system, the first energy storage device can be controlled to start energy release; when it is monitored that the operating state of the electric vehicle is that the energy of the second energy storage device is exhausted, the second energy storage device can be controlled to stop energy release.

[0054] In practical applications, the temperature control system may respond to the user's start-up operation on the onboard heating system of the electric vehicle and determine that the user needs heating or heat supply at this time, thereby controlling the first energy storage device to start energy release.

[0055] In one embodiment of the present invention, the control conditions of the temperature control module can be preset, and the control conditions can be associated with the electric energy of the electric vehicle required to turn on the air conditioner in the vehicle. For example, it can be set that when the electric energy of the electric vehicle is lower than a preset value, the temperature control system monitors the operating status of the electric vehicle and controls the first energy storage device to start or stop energy release according to the operating status.

[0056] The control conditions can also be associated with the start time and the outdoor temperature. For example, when the outdoor temperature reaches a first preset temperature or is lower than a second preset temperature, the temperature control system monitors the operating status of the electric vehicle and controls the first energy storage device to start or stop energy release according to the operating status.

[0057] In the embodiment of the present invention, by turning on the first energy storage device, the electric vehicle can supply heating air or cooling air without consuming electrical energy.

[0058] In one embodiment of the present invention, a first valve is provided on the circulation pipeline before the inlet of the first energy storage device, and a second valve is provided 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 valve and the second valve to control the first energy storage device to start or stop energy release.

[0059] Specifically, when the first valve is opened and the second valve is opened, the first energy storage device starts to release energy; when the first valve is closed and the second valve is closed, the first energy storage device stops releasing energy.

[0060] In practical applications, when there are multiple first energy storage devices, each first energy storage device is provided with a corresponding first valve and a second valve. By opening and closing the first valve and the second valve, each first energy storage device can be controlled to release energy in series or in parallel.

[0061] Similarly, when there are multiple second energy storage devices, a third valve can be set on the circulation pipeline after the outlet of each second energy storage device and a fourth valve can be set on the circulation pipeline before the inlet, and then the temperature control device can control the second energy storage device to cache energy by controlling the opening and closing of the third valve and the fourth valve, thereby realizing the second energy storage device as a temperature buffer device to adjust the temperature of the ultra-high temperature fluid working medium output by the first energy storage device.

[0062] In practical applications, the second energy storage device can be controlled to cache energy in series or in parallel by controlling the opening and closing of the third valve and the fourth valve.

[0063] In one embodiment of the present invention, the temperature control module includes a first temperature meter (such as Figure 1a T1 in the figure), a second temperature meter (such as Figure 1a T2 in the figure), a third temperature meter (such as Figure 1a T3 in the figure) and a fourth temperature meter (such as Figure 1a T4 in ).

[0064] Among them, the first thermometer monitors the maximum temperature of the first energy storage device, the second thermometer monitors the minimum temperature of the first energy storage device, the third thermometer monitors the maximum temperature of the second energy storage device, and the fourth thermometer monitors the minimum temperature of the second energy storage device.

[0065] In one embodiment of the present invention, the temperature control module is further used to monitor the interior temperature of the electric transportation 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.

[0066] Specifically, when there is a demand for heating air, when the temperature inside the vehicle is much lower than the preset temperature, the air intake speed can be increased to achieve rapid temperature rise. For example, a mapping relationship between the temperature difference between the temperature inside the vehicle and the preset temperature and the air intake speed can be preset, and after determining the temperature difference, the air intake speed corresponding to the temperature difference is determined according to the mapping relationship.

[0067] The temperature control module in the embodiment of the present invention also includes a fresh air device connected to the outlet of the second energy storage device. When the first energy storage device stores thermal energy, the fresh air device is turned on. The fresh air device is used to cool the gas output from the second storage tank to the preset temperature of the vehicle heating system for easy application in electric vehicles.

[0068] By adding fresh air equipment, the fresh air equipment can reasonably distribute the high-temperature gas flow and fresh air flow from the outlet of the second storage tank according to the required temperature. For example, assuming the outlet temperature of the second storage tank is 600°C and the gas volume is 0.01m / s; adding fresh air of 0.3m / s, the gas temperature entering the car will eventually reach 40°C.

[0069] The purpose of adding fresh air equipment in the embodiment of the present invention is to reduce the gas velocity of the high-temperature storage tank so that the heat output is relatively less; because the temperature required for heating is <100°C; and the temperature of the first storage tank is as high as 3000°C, and the energy level is quite different; by using fresh air equipment, the gas temperature at the outlet of the second storage tank can be reduced, which increases safety while also meeting the normal gas volume requirements of electric transportation vehicles.

[0070] Reference Figure 1b , which is a cooling and heating system in an embodiment of the present invention, the fresh air device 21 can be arranged on the circulation pipeline between the second energy storage device 102 and the electric transportation vehicle 103.

[0071] In one embodiment of the present invention, when there are multiple first energy storage devices, the top inlet of a target energy storage device among the multiple first energy storage devices can be connected to the bottom outlet of the second energy storage device through a circulation pipeline, and the bottom outlet of the first target energy storage device can be connected to the bottom outlet of the second device through a circulation pipeline, wherein the target energy storage device is the energy storage device that first releases energy among the multiple first energy storage devices; the cooling and heating system is used to transport the fluid working medium output from the bottom outlet of the second energy storage device to the target energy storage device through the circulation pipeline after the energy of the target energy storage device is released, and output it to the electric transportation vehicle after energy exchange in the target energy storage device.

[0072] That is, in the embodiment of the present invention, the energy release process can be divided into two stages. In the first stage, all the first energy storage devices release energy together, and the second energy storage device buffers part of the energy. The fluid working medium carrying part of the energy is then transported to the electric transportation vehicle to achieve cooling and heating of the vehicle.

[0073] In the second stage, after part of the energy of the first energy storage device (i.e., the target energy storage device) is released, the target energy storage device is separated from the first energy storage device and connected in series with the second energy storage device through a circulation pipeline to serve as a buffer device to cache energy.

[0074] Among them, the first valve and the third valve of the target energy storage device can be set as three-way valves. The first end of the first valve is connected to the gas transportation device, the second end is connected to the top of the target energy storage device, and the third end is connected to the bottom of the second energy storage device; the first end of the second valve is connected to the bottom of the first energy storage device, the second end is connected to the bottom of the other first energy storage device, and the third end is connected to the bottom of the second energy storage device. A fifth valve is set between the second energy storage device and the electric transportation vehicle. The fifth valve can be a three-way valve, the first end of the three-way valve is connected to the second energy storage device, the second end is connected to the electric transportation vehicle, and the third end is connected to the third end of the first valve.

[0075] Reference Figure 1c , showing a cooling and heating system in an embodiment of the present invention, the first energy storage device includes a target energy storage device 11, the valves corresponding to the target energy storage device 11 include a first valve 31 and a second valve 32, and a fifth valve 33 is arranged on the circulation pipeline at the outlet of the second energy storage device 102.

[0076] In the first stage, the first end of the first valve 31 is connected to the second end, and the third end is closed, so that the gas transport device can input the gas into the target energy storage device; the first end of the second valve 32 is connected to the second end, and the third end is closed, and the first end of the fifth valve is connected to the second end, and the third end is closed, so that the fluid working medium output by the first energy storage device can be input into the second energy storage device from the top of the second energy storage device. The second energy storage device then stores part of the energy and outputs it, which is then transported to the electric transportation vehicle 103 along the circulation pipeline.

[0077] In the second stage, the second end of the first valve 31 is connected to the third end, and the first end is closed, the first end of the second valve 32 is connected to the third end, and the second end is closed, the first end of the fifth valve 33 is closed, and the second end is connected to the third end, so that the target energy storage device 11 is independent of the other first energy storage devices, and the target energy storage device 11 is connected in series with the second energy storage device 102, and the fluid working medium output by the second energy storage device 102 flows into the target energy storage device 11 through the second valve 32, and then the target energy storage device stores part of the energy, which is transported to the fifth valve 33 through the first valve 31, and then transported to the electric transportation vehicle.

[0078] In one embodiment of the present invention, the first energy storage device is charged in an energy storage system, and the energy storage system includes a fluidized bed charging module, a fixed bed energy storage module, and a circulation pipeline connecting the fluidized bed charging module and the fixed bed energy storage module, the fluidized bed charging module is a fluidized bed heat charging device or a fluidized bed cold charging device, the fixed bed energy storage module includes a first fixed bed group consisting of a plurality of detachable fixed beds connected in series or in parallel, a second fixed bed connected in series with the first fixed bed group, and a first thermometer located at the top of the second fixed bed, and a second thermometer located at the bottom of the second fixed bed, a fluid working medium passes through the circulation pipeline, a third energy storage medium is filled in the fluidized bed cavity of the fluidized bed charging module, and a first energy storage medium is filled in the fixed bed cavity of the fixed bed energy storage module, wherein the first energy storage device is a fixed bed in the first fixed bed group.

[0079] In actual applications, after the fluid working medium flows into the fluidized bed charging module, the fluid working medium exchanges energy with the third energy storage medium, and the fluid working medium carries the energy to the fixed bed energy storage module, and stores energy in the fixed beds in the first fixed bed group in turn, and then outputs it from the second fixed bed. Through the above arrangement, the fixed beds in the first fixed bed group are filled with energy, and then the charged fixed beds can be removed for standby use. Specifically, the charged fixed bed can be used in the cooling and heating system of the electric transportation vehicle in the embodiment of the present invention as a first energy storage device to release energy.

[0080] In one embodiment of the present invention, when the first energy storage device stores thermal energy, the second energy storage device can be connected to a thermal energy conversion device to convert the thermal energy into other forms of energy required by the vehicle, such as electrical energy, mechanical energy, etc.

[0081] Specifically, when the heat energy conversion device is a thermoelectric conversion device, the thermoelectric conversion device may include a cold water pump, a water pipeline, and a steam power generation device. The water pipeline is partially placed in the second energy storage device. When the first energy storage device is turned on to release energy, the cold water pump is started, and water flows through the water pipeline. When the fluid working medium heated by the first energy storage device is input into the second energy storage device, it contacts the water pipeline, heats the water pipeline, cools the fluid working medium, and at the same time, the water in the water pipeline is heated to generate steam, and the generated steam enters the steam power generation device, converts heat energy into electrical energy, and realizes power supply for electric transportation vehicles.

[0082] When the thermal energy conversion device is a thermal energy and mechanical energy conversion device, the thermal energy conversion device can be an engine, and the fluid in the second energy storage device can intermittently enter the engine to expand and do work, thereby outputting mechanical energy, and then connecting with the wheel axle through the transmission to increase the vehicle's cruising range.

[0083] In the embodiment of the present invention, the cooling and heating system can realize the energy storage device to provide heat / cooling for pure electric vehicles without consuming battery energy, and the temperature range supported by the energy storage device is -250°C to 3000°C. Therefore, the cooling and heating system in the embodiment of the present invention can realize ultra-high and ultra-low temperature cooling and heating.
