Description

Technical Field

[0001] The present invention relates to the field of mobile charging, and in particular to a thermal management method and system based on a mobile charging vehicle. Background Art

[0002] A mobile charging vehicle is a movable charging device.

[0003] The advantages of mobile charging vehicles are high mobility, flexible deployment, rapid energy replenishment and adaptability to a variety of scenarios. Mobile charging vehicles can be used to charge at low electricity prices and discharge during peak hours to assist the power grid in balancing loads and reducing electricity costs. They can also play an advantage in emergency rescue and disaster response. Their mobility fills the gap in the charging network. Mobile charging vehicles include vehicles, carriages, energy storage batteries, charging systems and control systems. The energy storage batteries, charging systems and control systems are fixed in the carriages. The charging system is used to convert power inputs of different specifications into unified electrical energy stored in the energy storage batteries. The control system is used to regulate the temperature, humidity and charging status of the energy storage batteries.

[0004] When the storage battery is overheated, it is easy to cause the output of the mobile charging vehicle to be unstable, thereby causing the charging efficiency of the mobile charging vehicle to decrease. Summary of the Invention

[0005] In order to improve the stability of the use of mobile charging vehicles and timely reduce the temperature of energy storage batteries, the present invention provides a thermal management method and system based on mobile charging vehicles.

[0006] In a first aspect, the present invention provides a thermal management method based on a mobile charging vehicle, which adopts the following technical solutions:

[0007] A thermal management method based on a mobile charging vehicle, comprising:

[0008] Step 100: collecting the battery temperature of the energy storage battery;

[0009] Step 101: When the battery temperature is higher than a preset operating temperature, a temperature difference is determined in response to the battery temperature and the preset operating temperature, and an ambient temperature of the charging vehicle is collected;

[0010] Step 102: determining a cooling wind speed in response to the temperature difference and the ambient temperature, and retrieving the driving speed of the charging vehicle;

[0011] Step 103: determining a wind conduction coefficient in response to the cooling wind speed and the driving speed;

[0012] Step 104: determining an air guide area in response to the air guide coefficient;

[0013] Step 105: Control the preset air guide device to open according to the air guide area to introduce external wind to cool the battery.

[0014] By adopting the above technical solution, when the energy storage battery of the charging vehicle overheats during driving, the wind outside the vehicle is introduced into the vehicle compartment by using an air guide device, and the wind speed blowing into the vehicle compartment is adjusted by adjusting the wind guide area of ​​the air guide device, thereby reducing the temperature of the energy storage battery through the wind with a higher wind speed generated by the high-speed driving of the vehicle, thereby improving the stability of the mobile charging vehicle.

[0015] Optionally, also include:

[0016] Step 106: When the air guide area is greater than a preset air guide threshold, determining an area difference in response to the air guide area and the preset air guide threshold;

[0017] Step 107: determining a wind speed difference in response to the area difference;

[0018] Step 108: determining a humidification rate in response to the wind speed difference, and collecting a water tank liquid level in the water tank;

[0019] Step 109: determining an evaporation rate in response to the water tank liquid level and a preset air guide threshold;

[0020] Step 110: determining an opening factor in response to the humidification rate and the evaporation rate;

[0021] Step 111: determining a humidification area in response to the opening coefficient;

[0022] Step 112: Control the preset water tank to open a connection port communicating with the preset air guide device according to the humidification area.

[0023] By adopting the above technical solution, when the vehicle is traveling at a slow speed, the wind force generated during driving is small. At this time, in order to increase the wind speed, the wind guide area required to be expanded by the wind guide device is likely to be too large. By opening the connection port between the wind guide device and the water tank so that the wind introduced by the wind guide device blows through the water tank, the wind is cooled and humidified to improve the cooling effect of the wind, thereby improving the stability of the mobile charging vehicle.

[0024] Optionally, a water collection method is further included, and the water collection method includes:

[0025] Step 200: When the battery temperature is higher than a preset operating temperature, collecting ambient humidity;

[0026] Step 201: When the ambient humidity is higher than a preset water collection threshold, determining a heat absorption rate in response to the ambient humidity and a temperature difference;

[0027] Step 202: determining a heat absorption air volume in response to the heat absorption rate;

[0028] Step 203: determining a heat absorption area in response to the heat absorption air volume;

[0029] Step 204: Control the preset air guide device to open according to the heat absorption area to guide external wind force to the insulation layer preset outside the battery.

[0030] By adopting the above technical solution, when the outside humidity is too high, directly introducing high-humidity wind from the outside can easily cause excessive humidity in the car, thereby causing short circuits in the energy storage battery, charging system and control system in the car. The high-humidity wind is introduced into the car through the air guide device into an insulation layer that is isolated from the energy storage battery, charging system and control system, so as to reduce the short circuits in the energy storage battery, charging system and control system.

[0031] Optionally, the water collection method further comprises:

[0032] Step 205: When the ambient humidity is higher than a preset water collection threshold, determining a dew point temperature in response to the ambient humidity;

[0033] Step 206: When the dew point temperature is greater than the preset water collection temperature, determining a water collection temperature difference in response to the dew point temperature and the preset water collection temperature;

[0034] Step 207: determining a water collection rate in response to the water collection temperature difference;

[0035] Step 208: determining a water collection area in response to the water collection rate and the heat absorption air volume;

[0036] Step 209: Control the preset air guide device to open according to the water collection area to introduce the wind force of the isolation layer to the water collection plate preset in the water tank.

[0037] By adopting the above technical solution, the higher the external humidity, the higher the dew point temperature. The high-humidity wind is introduced into the water collecting plate in the water tank through the air guide device, so that the high-temperature and high-humidity wind condenses into water droplets through the water collecting plate with lower temperature, and drives the water droplets along the water collecting plate into the water tank, thereby maintaining the water level in the water tank.

[0038] Optionally, the water collection method further comprises:

[0039] Step 210: When the water tank liquid level is lower than a preset cooling threshold, retrieve the driving route;

[0040] Step 211: Retrieving regional humidity in response to the driving route, and retrieving a regional route in response to the driving route;

[0041] Step 212: determining a water collection route in response to the regional humidity and the regional route;

[0042] Step 213: generating a water collection suggestion in response to the water collection route;

[0043] Step 214: Control a preset prompt device to display the water collection suggestion.

[0044] By adopting the above technical solution, when the water level in the water tank is too low, the meteorological data and traffic route data of the vehicle's area are retrieved to plan a driving route with sufficient ambient water vapor, thereby reducing the loss of water in the water tank.

[0045] Optionally, a charging cooling method is further included, and the charging cooling method includes:

[0046] Step 300: When the driving speed is lower than a preset wind deflection threshold, retrieving battery charging information;

[0047] Step 301: Determine whether the device is in the charging process based on the charging information;

[0048] Step 302: When the vehicle is charging, determine a lower vehicle speed limit in response to the cooling wind speed and a preset wind guide threshold;

[0049] Step 303: determining a detour radius in response to the vehicle speed lower limit, and collecting a charging image of the charging vehicle;

[0050] Step 304: determining a detour path in response to the detour radius and the charging image;

[0051] Step 305: generating a driving suggestion in response to the detour route;

[0052] Step 306: Control a preset prompt device to display the driving suggestion.

[0053] By adopting the above technical solution, when the vehicle's driving speed is too low, it is difficult to form a large wind speed, and the battery is likely to continue to generate heat during charging. At this time, the prompt device plans a route for the vehicle to continue driving to generate stable wind force, thereby generating stable wind force through driving.

[0054] Optionally, the charging cooling method further includes:

[0055] Step 307: When charging, collect ambient wind speed and direction;

[0056] Step 308: When the ambient wind speed is higher than a preset collection threshold, the difference between the vehicle speed lower limit and the ambient wind speed is calculated and defined as the vehicle speed lower limit;

[0057] Step 309: determining a headwind distance in response to the vehicle speed lower limit;

[0058] Step 310: Update the detour path in response to the ambient wind direction, windward distance, and charging image.

[0059] By adopting the above technical solution, when the wind in the area where the vehicle is located is strong, the direction of the vehicle's travel is adjusted to improve the efficiency of introducing wind when the vehicle is traveling against the wind, and the wind force is used to reduce the speed at which the vehicle needs to travel, thereby improving the stability of the air volume introduced by the wind guide device.

[0060] Optionally, the charging cooling method further includes:

[0061] Step 311: When in the charging process, determining a movement space in response to the charging image;

[0062] Step 312: When the moving space is less than a preset driving threshold, determining a cooling area in response to the ambient wind direction and the charging image;

[0063] Step 313: Determine a cooling position based on the cooling area and the preset driving width;

[0064] Step 314: generating a cooling recommendation in response to the cooling location;

[0065] Step 315: Control a preset prompt device to display the cooling suggestion.

[0066] By adopting the above technical solution, when there is no road for the vehicle to circulate around the location of the vehicle, the area on the windward side where the charging vehicle can park is found according to the wind direction of the area, and the location where there is a road for the charging vehicle to enter is screened out from the area, so that the driver is advised to drive the vehicle to receive the natural wind force from the outside through the prompt device.

[0067] Optionally, the charging cooling method further includes:

[0068] Step 316: Determine a zone height in response to the cooling zone;

[0069] Step 317: Determine a wind blocking rate in response to the area height, the ambient wind direction, and a preset vehicle cabin height;

[0070] Step 318: Determine a cooling efficiency in response to the ambient wind speed and the wind blocking rate;

[0071] Step 319: determining a lower limit of temperature reduction in response to the ambient wind speed;

[0072] Step 320: Update the cooling area in response to the cooling efficiency and the cooling lower limit.

[0073] By adopting the above technical solution, when there are obstructions on the ground, the natural wind blowing towards the charging vehicle is easily blocked by the obstructions on the ground, thereby reducing the cooling effect of the natural wind on the charging vehicle. A location with a stronger cooling effect is selected on the windward side where the charging vehicle can be parked, thereby improving the accuracy of the cooling recommendation.

[0074] In a second aspect, the present application provides a thermal management system based on a mobile charging vehicle, which adopts the following technical solutions:

[0075] A thermal management system based on a mobile charging vehicle, comprising:

[0076] Acquisition module, used to collect battery temperature, ambient temperature, water tank level, ambient humidity, charging image, ambient wind speed and ambient wind direction;

[0077] A memory, configured to store any one of the above-mentioned thermal management methods based on a mobile charging vehicle;

[0078] The processor can load and execute the program in the memory.

[0079] By adopting the above technical solution, when the energy storage battery of the charging vehicle overheats during driving, the wind outside the vehicle is introduced into the vehicle compartment by using an air guide device, and the wind speed blowing into the vehicle compartment is adjusted by adjusting the wind guide area of ​​the air guide device, thereby reducing the temperature of the energy storage battery through the wind with a higher wind speed generated by the high-speed driving of the vehicle, thereby improving the stability of the mobile charging vehicle.

[0080] In summary, this application includes at least one of the following beneficial technical effects:

[0081] When the energy storage battery overheats during driving, the wind guide device is used to introduce the wind outside the vehicle into the vehicle compartment. The wind speed blowing into the vehicle compartment is adjusted by adjusting the wind guide area of ​​the wind guide device. In this way, the high wind speed generated by the high speed of the vehicle can reduce the temperature of the energy storage battery and improve the stability of the mobile charging vehicle.

[0082] When the vehicle is traveling at a slow speed, the wind force generated during driving is small. At this time, in order to increase the wind speed, the wind guide device needs to expand the wind guide area too large. By opening the connection port between the wind guide device and the water tank, the wind introduced by the wind guide device is blown through the water tank, thereby cooling and humidifying the wind to improve the cooling effect of the wind and improve the stability of the mobile charging vehicle.

[0083] When the outside humidity is too high, directly introducing high-humidity wind from the outside can easily cause excessive humidity in the car, thereby causing short circuits in the energy storage batteries, charging systems and control systems in the car. The high-humidity wind is introduced into the car through an air guide device into an insulation layer that is isolated from the energy storage batteries, charging systems and control systems to reduce short circuits in the energy storage batteries, charging systems and control systems.

[0084] Figure 1 The present invention is a flow chart of a thermal management method based on a mobile charging vehicle. DETAILED DESCRIPTION

[0085] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0086] Reference Figure 1 , a thermal management method based on a mobile charging vehicle, comprising:

[0087] Step 100: Collect the battery temperature of the energy storage battery.

[0088] The energy storage battery is a battery used to store electrical energy in the vehicle compartment. The battery temperature is the temperature value of the energy storage battery. The battery temperature can be collected by a temperature sensor. The method of collecting the battery temperature is selected by the staff based on actual conditions and will not be elaborated here.

[0089] Step 101: When the battery temperature is higher than a preset operating temperature, a temperature difference is determined in response to the battery temperature and the preset operating temperature, and the ambient temperature of the charging vehicle is collected.

[0090] The operating temperature refers to the maximum temperature at which the battery can stably output electrical energy. The operating temperature is selected by staff based on actual conditions and is not detailed here. A battery temperature higher than the operating temperature indicates that the energy storage battery is too hot and requires timely cooling. The temperature difference refers to the difference used to indicate high-temperature conditions of the energy storage battery. The temperature difference can be calculated as the difference between the battery temperature and the operating temperature. The ambient temperature refers to the temperature outside the vehicle compartment. A temperature sensor can be used to collect the ambient temperature. The method for calculating the temperature difference and collecting the ambient temperature is selected by staff based on actual conditions and is not detailed here.

[0091] Step 102: Determine the cooling wind speed in response to the temperature difference and the ambient temperature, and retrieve the driving speed of the charging vehicle.

[0092] The cooling wind speed refers to the wind speed required to cool the high-temperature energy storage battery to a temperature below the operating temperature, that is, the wind speed required to reduce the temperature difference to 0. The cooling wind speed can be obtained from the temperature relationship table. The temperature relationship table refers to a data table that records different temperature differences and ambient temperatures and their corresponding cooling wind speeds.

[0093] The driving speed refers to the speed of the charging vehicle. The driving speed can be directly retrieved from the vehicle computer system of the charging vehicle. The method of retrieving the driving speed is selected by the staff according to the actual situation and will not be elaborated here.

[0094] Step 103: Determine a wind conduction coefficient in response to the cooling wind speed and the driving speed.

[0095] The insulating layer refers to the space set between the car and the energy storage battery for air flow to pass through. The wind guide device refers to the equipment used to introduce external wind into the car. The wind guide device is generally composed of a pipe with a baffle at one end. The direction of the pipe is consistent with the driving direction of the vehicle. One end of the pipe is set outside the car, and the other end of the pipe is connected to the car or the insulating layer. The baffle is circumferentially arranged at the end of the pipe outside the car. The angle of the baffle can be adjusted to adjust the air volume introduced into the pipe. The insulating layer and wind guide device are selected by the staff according to actual conditions and will not be elaborated here.

[0096] The wind conduction coefficient refers to a value used to show the amount of air that needs to be introduced through the wind guide device, where the wind speed outside the vehicle is shown by the driving speed. Generally, the quotient of the cooling wind speed and the driving speed is used as the wind conduction coefficient.

[0097] Step 104: Determine a wind guide area in response to the wind guide coefficient.

[0098] The wind guide area refers to the area value that the wind guide device needs to expand. The wind guide area can be queried from the area data table. The area data table refers to a data table that records different wind guide coefficients and their corresponding wind guide areas.

[0099] Step 105: Control the preset air guide device to open according to the air guide area to introduce external wind to cool the battery.

[0100] When the energy storage battery overheats during driving, an air guide device is used to introduce wind from outside the vehicle into the vehicle compartment, and the wind speed blowing into the vehicle compartment is adjusted by adjusting the wind guide area of ​​the air guide device. In this way, the temperature of the energy storage battery is reduced by the wind with a higher wind speed generated by the high-speed driving of the vehicle, thereby improving the stability of the mobile charging vehicle.

[0101] A thermal management method based on a mobile charging vehicle, further comprising:

[0102] Step 106: When the wind guide area is greater than a preset wind guide threshold, an area difference is determined in response to the wind guide area and the preset wind guide threshold.

[0103] The wind guide threshold refers to the maximum area that the wind guide device can expand. The wind guide threshold is selected by staff based on actual conditions and is not detailed here. If the wind guide area is greater than the wind guide threshold, it means the wind speed outside the vehicle is too low. In this case, the wind speed introduced from the outside is insufficient to effectively reduce the temperature of the energy storage battery. The area difference is a value used to indicate the lack of expansion area of ​​the wind guide device. The area difference is generally calculated as the difference between the wind guide area and the wind guide threshold.

[0104] Step 107: Determine a wind speed difference in response to the area difference.

[0105] The wind speed difference refers to a value used to show the lack of external wind speed. The wind speed difference can be queried from the wind difference relationship table. The wind difference relationship table refers to a data table that records different area differences and their corresponding wind speed differences.

[0106] Step 108: Determine a humidification rate in response to the wind speed difference, and collect a water tank liquid level in the water tank.

[0107] The water tank refers to a container fixed on the charging vehicle and used to store clean water. The water tank is connected to the pipes of the insulation layer and the air guide device respectively, and the connecting ports of the water tank and the pipes of the insulation layer and the air guide device are all located above the water tank to reduce the outflow of liquid water in the water tank from the connecting ports. Valves are provided on the connecting ports to control the opening and closing of the connecting ports. The water tank is selected by the staff according to actual conditions and will not be elaborated here.

[0108] The humidification rate refers to the rate at which the wind speed and humidity need to be increased in order to compensate for the wind speed difference. The humidification rate can be found from the humidification relationship table, which is a data table that records different wind speed differences and their corresponding humidification rates.

[0109] The water tank liquid level refers to the water level of the liquid water in the water tank. The water tank liquid level can be collected by a liquid level sensor. The method of collecting the water tank liquid level is selected by the staff according to the actual situation and will not be elaborated here.

[0110] Step 109: Determine an evaporation rate in response to the water tank liquid level and a preset air flow threshold.

[0111] The evaporation rate refers to the rate at which liquid water in the water tank evaporates, that is, the humidification rate of the water tank for the air flowing through the pipe of the air guide device. The higher the water tank liquid level and the larger the air guide threshold, the greater the evaporation rate. The evaporation rate can be queried from the evaporation relationship table. The evaporation relationship table refers to a data table that records different water tank liquid levels and air guide thresholds and their corresponding evaporation rates.

[0112] Step 110: Determine an opening factor in response to the humidification rate and the evaporation rate.

[0113] The opening coefficient refers to the value of the opening size of the valve used to show the connectivity of the connecting port between the water tank and the pipe of the air guide device. Generally, the quotient of the humidification rate and the evaporation rate is calculated as the opening coefficient.

[0114] Step 111: Determine a humidification area in response to the opening coefficient.

[0115] The humidification area refers to the opening area of ​​the valve that controls the connectivity of the connecting port between the water tank and the pipe of the air guide device. The larger the opening coefficient, the larger the required humidification area. The humidification area can be queried from the opening relationship table. The opening relationship table refers to a data table that records different opening coefficients and their corresponding humidification areas.

[0116] Step 112: Control the preset water tank to open a connection port communicating with the preset air guide device according to the humidification area.

[0117] When the vehicle is traveling at a slow speed, the wind force generated during driving is small. At this time, in order to increase the wind speed, the wind guide area required to be expanded by the wind guide device is likely to be too large. By opening the connection port between the wind guide device and the water tank so that the wind introduced by the wind guide device blows through the water tank, the wind is cooled and humidified to improve the cooling effect of the wind and improve the stability of the mobile charging vehicle.

[0118] Water harvesting methods include:

[0119] Step 200: When the battery temperature is higher than a preset operating temperature, collect the ambient humidity.

[0120] Ambient humidity refers to the absolute humidity value at the location of the charging vehicle. The ambient humidity can be collected by a humidity sensor installed outside the vehicle. The method of collecting the ambient humidity is selected by the staff based on actual conditions and will not be elaborated here.

[0121] Step 201: When the ambient humidity is higher than a preset water collection threshold, determine a heat absorption rate in response to the ambient humidity and a temperature difference.

[0122] The water collection threshold refers to the minimum humidity value at which water vapor carried by wind can easily cause short circuits and other faults in the energy storage battery. This threshold is selected by staff based on actual conditions and is not detailed here. Ambient humidity above the water collection threshold indicates excessive moisture in the outside air, and directly introducing outside air into the vehicle can easily cause energy storage battery failure. The heat absorption rate refers to the rate at which high-humidity air absorbs heat. The greater the difference between ambient humidity and temperature, the greater the heat absorption rate. The heat absorption rate can be found in the heat absorption relationship table, which records the corresponding heat absorption rates for different ambient humidity and temperature differences.

[0123] Step 202: Determine the heat absorption air volume in response to the heat absorption rate.

[0124] The heat absorption air volume refers to the minimum volume through which the wind can fully carry away the heat in unit time. The greater the heat absorption rate, the smaller the heat absorption air volume. The heat absorption air volume can be queried from the air volume relationship table. The air volume relationship table refers to a data table that records different heat absorption rates and their corresponding heat absorption air volumes.

[0125] Step 203: Determine a heat absorption area in response to the heat absorption air volume.

[0126] The heat absorption area refers to the area value that the air guide device needs to expand. The larger the heat absorption air volume, the larger the heat absorption area that needs to be expanded. The heat absorption area can be queried from the expansion relationship table. The expansion relationship table refers to a data table that records different heat absorption air volumes and their corresponding heat absorption areas.

[0127] Step 204: Control the preset air guide device to open according to the heat absorption area to guide external wind force to the insulation layer preset outside the battery.

[0128] When the outside humidity is too high, directly introducing high-humidity wind from the outside can easily cause excessive humidity in the car, thereby causing short circuits in the energy storage batteries, charging systems and control systems in the car. The high-humidity wind is introduced into the car through an air guide device into an insulation layer that is isolated from the energy storage batteries, charging systems and control systems to reduce short circuits in the energy storage batteries, charging systems and control systems.

[0129] Water harvesting methods also include:

[0130] Step 205: When the ambient humidity is higher than a preset water collection threshold, determine the dew point temperature in response to the ambient humidity.

[0131] The dew point temperature refers to the maximum temperature at which water vapor in the air easily condenses into water droplets. The method for determining the dew point temperature is common knowledge among those skilled in the art and will not be elaborated here.

[0132] Step 206: When the dew point temperature is greater than the preset water collection temperature, determine a water collection temperature difference in response to the dew point temperature and the preset water collection temperature.

[0133] A water collecting plate refers to a device fixed in a water tank to drive water vapor in the air to condense into water droplets. It is generally made of a metal plate. The water collecting plate is set corresponding to the connecting port of the water tank and the insulation layer, and the water collecting plate is generally set vertically to facilitate the water droplets condensed on the water collecting plate to flow into the water tank. The water collecting plate is selected by the staff according to actual conditions and will not be elaborated here.

[0134] The water collection temperature refers to the temperature of the water collection plate at room temperature. The water collection temperature is selected by staff based on actual conditions and is not detailed here. A dew point temperature greater than the water collection temperature indicates that water droplets easily condense when the outside air contacts the water collection plate. The water collection temperature difference is a numerical value used to indicate the ease with which water droplets condense on the water collection plate. The water collection temperature difference is generally calculated as the difference between the dew point temperature and the water collection temperature. A larger water collection temperature difference indicates a greater likelihood of water droplets condensing.

[0135] Step 207: Determine a water collection rate in response to the water collection temperature difference.

[0136] The water collection rate refers to the maximum speed at which water droplets can fully condense when the air flow passes through the water collection plate. The greater the water collection temperature difference, the greater the water collection rate. The water collection rate can be queried from the rate relationship table. The rate relationship table refers to a data table that records different water collection temperature differences and their corresponding water collection rates.

[0137] Step 208: Determine a water collection area in response to the water collection rate and the heat absorption air volume.

[0138] The water collection area refers to the opening and closing size of the valve that controls the connectivity between the water tank and the insulation layer. Any value greater than the water collection rate and less than the heat absorption air volume can be used as the water collection air volume. The average value of the water collection rate and the heat absorption air volume is preferably used as the water collection air volume. The water collection area corresponding to the water collection air volume is then queried from the water collection relationship table. The water collection relationship table refers to a data table that records different water collection air volumes and their corresponding water collection areas. When the water collection rate is greater than the heat absorption air volume, the heat absorption air volume is used as the water collection air volume.

[0139] Step 209: Control the preset air guide device to open according to the water collection area to introduce the wind force of the isolation layer to the water collection plate preset in the water tank.

[0140] The higher the outside humidity, the higher the dew point temperature. The high-humidity wind is introduced into the water collecting plate in the water tank through the air guide device, so that the high-temperature and high-humidity wind condenses into water droplets through the water collecting plate with lower temperature, and drives the water droplets along the water collecting plate into the water tank, thereby maintaining the water level in the water tank.

[0141] Water harvesting methods also include:

[0142] Step 210: When the water tank liquid level is lower than a preset cooling threshold, the driving route is retrieved.

[0143] The cooling threshold refers to the minimum liquid level required to maintain the cooling effect of the water tank. This threshold is selected by staff based on actual conditions and is not detailed here. A water tank level below the cooling threshold indicates that the water level is too low and requires immediate replenishment. The driving route is a dataset containing information such as the charging vehicle's location, destination, and speed. The driving route can be retrieved directly from the charging vehicle's onboard system. The method for retrieving the driving route is selected by staff based on actual conditions and is not detailed here.

[0144] Step 211: Retrieve regional humidity in response to the driving route, and retrieve regional routes in response to the driving route.

[0145] Regional humidity refers to the humidity distribution in the area where the charging vehicle is located. It can be retrieved by combining the location of the charging vehicle included in the driving route with meteorological data. Meteorological data can be retrieved from the local weather station. The method of retrieving regional humidity is selected by the staff based on actual conditions and will not be elaborated here.

[0146] The regional route refers to the distribution of traffic routes in the area where the charging vehicle is located. It can be retrieved by combining the location of the charging vehicle included in the driving route with traffic data. The traffic data can be retrieved from the navigation system. The method of retrieving the regional route is selected by the staff based on actual conditions and will not be elaborated here.

[0147] Step 212: Determine a water collection route in response to the regional humidity and the regional route.

[0148] The water collection route refers to the route with the richest water vapor among all the routes from the location of the charging vehicle to the destination. The destination can be retrieved from the driving route first, and then all routes from the location of the charging vehicle to the destination can be planned from the regional route. Finally, the humidity of each route is calculated based on the route and regional humidity, and the route with the highest humidity is selected as the water collection route. The method for determining the water collection route is selected by the staff according to the actual situation and will not be elaborated here.

[0149] Step 213: Generate a water collection suggestion in response to the water collection route.

[0150] A prompting device is a device used to display information to the driver, typically a display screen. The prompting device is selected by the operator based on the actual situation and is not described in detail here. A water collection suggestion is a dataset of water collection routes presented to the driver via the prompting device. The method for generating water collection suggestions is common knowledge in the art and is not described here.

[0151] Step 214: Control a preset prompt device to display the water collection suggestion.

[0152] When the water level in the water tank is too low, the weather data and traffic route data of the vehicle's area are retrieved to plan a driving route with more sufficient ambient water vapor, thereby reducing the loss of water in the water tank.

[0153] Charge cooling methods include:

[0154] Step 300: When the driving speed is lower than a preset wind deflection threshold, the battery charging information is retrieved.

[0155] Charging information refers to data containing the input and output of electrical energy of the energy storage battery, which can be retrieved from the control system in the car. The method of retrieving the charging information is selected by the staff based on the actual situation and will not be elaborated here.

[0156] Step 301: Determine whether the battery is in the charging process based on the charging information.

[0157] Being in the charging process means that the battery is outputting or inputting electrical energy. The judgment method of the charging process is selected by the staff according to the actual situation and will not be elaborated here.

[0158] Step 302: When in the charging process, determine the lower limit of the vehicle speed in response to the cooling wind speed and a preset wind guide threshold.

[0159] The lower speed limit refers to the minimum external wind speed required to form an airflow with a cooling wind speed when the wind guide device is deployed to its maximum, that is, the minimum speed the vehicle needs to travel. The wind guide coefficient corresponding to the wind guide threshold can be queried from the area data table, and then the quotient of the cooling wind speed and the wind guide coefficient is calculated as the lower speed limit.

[0160] Step 303: Determine a detour radius in response to the vehicle speed lower limit, and collect a charging image of the charging vehicle.

[0161] The detour radius refers to the radius of the circular motion of the charging vehicle around the charging or charged equipment. The detour radius is adjusted to maintain the vehicle's angular velocity during travel. The greater the lower speed limit, the larger the detour radius. The calculation method for the detour radius is common knowledge in the field and is not detailed here. The charging image refers to an image of the area where the charging vehicle is located. This image can be captured by the charging vehicle's camera. The method for capturing the charging image is selected by the operator based on actual circumstances and is not detailed here.

[0162] Step 304: Determine a detour path in response to the detour radius and the charging image.

[0163] The detour path refers to the route that the charging vehicle takes in a circular motion around the charging or charged equipment. The method for determining the detour path is common knowledge among those skilled in the art and will not be elaborated here.

[0164] Step 305: Generate a driving suggestion in response to the detour route.

[0165] Driving suggestions refer to a data set of detour routes displayed to the driver through a prompt device. The method of generating driving suggestions is common knowledge in this field and will not be described in detail here.

[0166] Step 306: Control a preset prompt device to display the driving suggestion.

[0167] When the vehicle's driving speed is too low, it is difficult to form a large wind speed, and the battery is likely to continue to generate heat during charging. At this time, the device is prompted to plan a route for the vehicle to continue driving to generate stable wind, thereby generating stable wind through driving.

[0168] The charging cooling method also includes:

[0169] Step 307: When in the charging process, collect the ambient wind speed and ambient wind direction.

[0170] The ambient wind speed refers to the wind speed value at the location of the charging vehicle, and the ambient wind direction refers to the wind direction at the location of the charging vehicle. The ambient wind speed and ambient wind direction can be collected by a wind sensor installed on the vehicle. The method of collecting the ambient wind speed and ambient wind direction is selected by the staff according to the actual situation and will not be elaborated here.

[0171] Step 308: When the ambient wind speed is higher than a preset collection threshold, the difference between the vehicle speed lower limit and the ambient wind speed is calculated and defined as the vehicle speed lower limit.

[0172] The collection threshold refers to the minimum wind speed that can be imported through the wind guide device. The collection threshold is selected by the staff based on the actual situation and is not detailed here. If the ambient wind speed is higher than the collection threshold, the ambient wind speed can be collected, and the ambient wind force can be used to reduce the required speed of the charging vehicle.

[0173] Step 309: Determine the headwind distance in response to the vehicle speed lower limit.

[0174] The headwind distance refers to the point on the vehicle's route that is farthest from the charging device or the device being charged. The detour radius can be calculated based on the vehicle's lower speed limit. The length of the charging vehicle's route can then be calculated based on the detour radius. Finally, the quotient of the length and 4 is calculated as the headwind distance.

[0175] Step 310: Update the detour path in response to the ambient wind direction, windward distance, and charging image.

[0176] When the wind force at the location of the charging vehicle is strong, a round trip route between a first position point of the charging device or the charged device at a distance upwind along the ambient wind direction and a second position point of the charging device or the charged device at a distance upwind along the opposite direction of the ambient wind direction is used as a new detour route to improve the efficiency of the wind guide device in introducing air volume when the charging vehicle is traveling against the wind, thereby utilizing wind force to reduce the speed at which the vehicle needs to travel, and thereby improving the stability of the air volume introduced by the wind guide device.

[0177] The charging cooling method also includes:

[0178] Step 311 : When in the charging process, determine a movement space in response to the charging image.

[0179] The moving space refers to the area in the area where the charging vehicle is located that can be used for the charging vehicle to travel back and forth. The moving space can be identified by image recognition technology. The identification method of the moving space is common knowledge in this field and will not be described here.

[0180] Step 312: When the moving space is smaller than a preset driving threshold, a cooling area is determined in response to the ambient wind direction and the charging image.

[0181] The driving threshold refers to the minimum area required for the charging vehicle to travel back and forth. This threshold is selected by staff based on actual conditions and is not detailed here. A movement space less than the driving threshold indicates that there is no space for the charging vehicle to travel back and forth in the area where the charging vehicle is located. The cooling zone is defined as an area with a high cooling effect. Generally, the area in the charging image that is opposite to the ambient wind direction of the charging vehicle is used as the cooling zone. The method for determining the cooling zone is common knowledge in this field and is not detailed here.

[0182] Step 313: Determine a cooling position based on the cooling area and the preset driving width.

[0183] The driving width refers to the minimum width of the road that a charging vehicle can pass through, i.e., the width of the charging vehicle. The driving width is selected by the staff based on actual conditions and is not detailed here. The cooling position refers to the location within the cooling area that the charging vehicle can reach. Image recognition technology can be used to identify roads and their widths from the charging image. Roads with a width greater than the driving width are then selected, and the location on the road farthest from the charging vehicle in the ambient wind direction is selected as the cooling position. The method for determining the cooling position is common knowledge in the field and is not detailed here.

[0184] Step 314: Generate a cooling recommendation in response to the cooling location.

[0185] The cooling suggestion refers to a data set used to display the cooling location and the route to the cooling location to the driver through a prompt device. The method for generating the cooling suggestion is common knowledge among people in this field and will not be described in detail here.

[0186] Step 315: Control a preset prompt device to display the cooling suggestion.

[0187] When there is no road for the vehicle to circulate around the vehicle's location, the area on the windward side where the charging vehicle can park is found according to the wind direction of the area, and the location where there is a road for the charging vehicle to enter is screened out from the area, so as to suggest the driver to drive the vehicle to receive the natural wind force from the outside through the prompt device.

[0188] The charging cooling method also includes:

[0189] Step 316: Determine a zone height in response to the cooling zone.

[0190] The regional height refers to the height value of each point in the cooling area, and the regional height can be identified by image recognition technology. The method for identifying the regional height is common knowledge among people in this field and will not be described in detail here.

[0191] Step 317: Determine the wind blocking rate in response to the area height, the ambient wind direction and the preset vehicle cabin height.

[0192] The compartment height refers to the maximum height of the charging vehicle compartment. The compartment height is selected by the staff based on actual conditions and is not detailed here. The wind blocking ratio refers to the ratio of wind blocked at each location in the cooling area. The wind blocking ratio can be calculated as the quotient of the area height opposite to the ambient wind direction at each location in the cooling area and the compartment height. The calculation method of the wind blocking ratio is common knowledge in this field and is not detailed here.

[0193] Step 318: Determine the cooling efficiency in response to the ambient wind speed and the wind blocking rate.

[0194] Cooling efficiency refers to the value that shows the cooling effect of external wind force. Generally, the product of ambient wind speed and wind blocking rate is calculated as the cooling efficiency.

[0195] Step 319: Determine a lower limit of temperature reduction in response to the ambient wind speed.

[0196] The lower limit of temperature reduction refers to a value used to show the cooling effect of the wind force at the location of the charging vehicle. The method for determining the lower limit of temperature reduction is common knowledge in this field and will not be described in detail here.

[0197] Step 320: Update the cooling area in response to the cooling efficiency and the cooling lower limit.

[0198] When there are obstructions on the ground, the natural wind blowing towards the charging vehicle is easily blocked by the obstructions on the ground, resulting in a decrease in the cooling effect of the natural wind on the charging vehicle. Areas in the cooling area where the cooling efficiency is lower than the lower limit of the cooling are screened out, thereby selecting locations in the cooling area with stronger cooling effects, thereby improving the accuracy of the cooling recommendations.
