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 a mobile charging vehicle lie in its high mobility, flexible deployment, fast energy replenishment, and adaptability to various scenarios. By using the mobile charging vehicle to charge during off-peak electricity prices and discharge during peak hours, it can assist the power grid in balancing the load, reduce electricity costs, and can play an advantage in emergency rescue and disaster response. Its mobility fills the gap in the charging network. The mobile charging vehicle includes a vehicle, a carriage, energy storage batteries, a charging system, and a control system. Among them, the energy storage batteries, the charging system, and the control system are fixed in the carriage. The charging system is used to convert different specifications of power inputs into unified electric energy and store it in the energy storage batteries, and the control system is used to regulate the temperature, humidity, and charging status of the energy storage batteries.

[0004] When the storage battery overheats, it is likely to cause an unstable output of the mobile charging vehicle, resulting in a decrease in the charging efficiency of the mobile charging vehicle. Summary of the Invention

[0005] In order to improve the stability of the mobile charging vehicle in use and be able to timely reduce the temperature value of the energy storage battery, the present invention provides a thermal management method and system based on a mobile charging vehicle.

[0006] In a first aspect, the present invention provides a thermal management method based on a mobile charging vehicle, adopting the following technical solution: A thermal management method based on a mobile charging vehicle includes: Step 100: Collect the battery temperature of the energy storage battery; Step 101: When the battery temperature is higher than a preset working temperature, determine the temperature difference in response to the battery temperature and the preset working temperature, and collect the ambient temperature of the charging vehicle; 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; Step 103: Determine the air guiding coefficient in response to the cooling wind speed and the driving speed; Step 104: Determine the air guiding area in response to the air guiding coefficient; Step 105: Control a preset air guiding device to open according to the air guiding area to introduce external wind power for battery cooling.

[0007] By adopting the above technical solution, when the energy storage battery overheats during the driving of the charging vehicle, the air outside the vehicle is introduced into the carriage by means of the air guiding device, and the wind speed blown into the carriage is adjusted by adjusting the air guiding area of the air guiding device, so as to reduce the temperature of the energy storage battery by the wind with a relatively large wind speed generated during the high-speed driving of the vehicle, and improve the stability of the mobile charging vehicle during use.

[0008] Optionally, it further includes: Step 106: When the air guiding area is greater than a preset air guiding threshold, determine the area difference in response to the air guiding area and the preset air guiding threshold; Step 107: Determine the wind speed difference in response to the area difference; Step 108: Determine the humidification rate in response to the wind speed difference, and collect the water tank level in the water tank; Step 109: Determine the evaporation rate in response to the water tank level and the preset air guiding threshold; Step 110: Determine the opening coefficient in response to the humidification rate and the evaporation rate; Step 111: Determine the humidification area in response to the opening coefficient; Step 112: Control the preset water tank to open the connection port communicating with the preset air guiding device according to the humidification area.

[0009] By adopting the above technical solution, when the vehicle is driving at a relatively low speed, the wind generated during the driving process is relatively small. At this time, the air guiding area required for the air guiding device to increase the wind speed is likely to be too large. By opening the connection port between the air guiding device and the water tank, the wind introduced by the air guiding device blows through the water tank, thereby cooling and humidifying the wind to improve the cooling effect of the wind and the stability of the mobile charging vehicle during use.

[0010] Optionally, it further includes a water collection method, and the water collection method includes: Step 200: When the battery temperature is higher than the preset working temperature, collect the ambient humidity; Step 201: When the ambient humidity is higher than the preset water collection threshold, determine the heat absorption rate in response to the ambient humidity and the temperature difference; Step 202: Determine the heat absorption air volume in response to the heat absorption rate; Step 203: Determine the heat absorption area in response to the heat absorption air volume; Step 204: Control the preset air guiding device to open according to the heat absorption area to introduce the external wind force to the isolation layer preset outside the battery.

[0011] By adopting the above technical solution, when the external humidity is too high, directly introducing the high-humidity wind from the outside easily causes the humidity inside the carriage to be too high, which may lead to short circuits in the energy storage battery, charging system, and control system inside the carriage. The high-humidity wind is introduced into an isolation layer inside the carriage that is isolated from the energy storage battery, charging system, and control system through a wind guiding device to reduce the occurrence of short circuits in the energy storage battery, charging system, and control system.

[0012] Optionally, the water collection method further includes: Step 205: When the environmental humidity is higher than a preset water collection threshold, determine the dew point temperature in response to the environmental humidity; Step 206: When the dew point temperature is not greater than a preset water collection temperature, determine the water collection temperature difference in response to the dew point temperature and the preset water collection temperature; Step 207: Determine the water collection rate in response to the water collection temperature difference; Step 208: Determine the water collection area in response to the water collection rate and the heat absorption air volume; Step 209: Control a preset wind guiding device to open according to the water collection area to introduce the wind into the isolation layer to a water collection plate preset in a water tank.

[0013] By adopting the above technical solution, the higher the external humidity, the higher the dew point temperature. The high-humidity wind is introduced onto the water collection plate in the water tank through the wind guiding device, so that the high-temperature and high-humidity wind condenses into water droplets by the relatively low-temperature water collection plate, and the water droplets are driven along the water collection plate into the water tank, thereby maintaining the water volume in the water tank.

[0014] Optionally, the water collection method further includes: Step 210: When the water level in the water tank is lower than a preset cooling threshold, retrieve the driving route; Step 211: Retrieve the regional humidity in response to the driving route, and retrieve the regional route in response to the driving route; Step 212: Determine the water collection route in response to the regional humidity and the regional route; Step 213: Generate a water collection suggestion in response to the water collection route; Step 214: Control a preset prompt device to display the water collection suggestion.

[0015] By adopting the above technical solution, when the water volume in the water tank is too low, the meteorological data and traffic route data of the area where the vehicle is located are retrieved, so as to plan a driving route with relatively sufficient environmental water vapor, thereby reducing the loss of the water volume in the water tank.

[0016] Optionally, it further includes a charging cooling method, and the charging cooling method includes: Step 300: When the driving speed is lower than a preset wind guiding threshold, retrieve the charging information of the battery; Step 301: Determine whether it is in the charging process from the charging information; 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 air guiding threshold; Step 303: Determine the bypass radius in response to the lower limit of the vehicle speed, and collect the charging image of the charging vehicle; Step 304: Determine the bypass path in response to the bypass radius and the charging image; Step 305: Generate a driving suggestion in response to the bypass path; Step 306: Control a preset prompting device to display the driving suggestion.

[0017] By adopting the above technical solution, when the driving speed of the vehicle is too low, it is difficult to form a relatively large wind speed, and heat is easily continuously generated during the charging process of the battery. At this time, the prompting device plans a route for the vehicle to continuously drive to generate a stable wind, so as to generate a stable wind through driving.

[0018] Optionally, the charging cooling method further includes: Step 307: When in the charging process, collect the ambient wind speed and ambient wind direction; Step 308: When the ambient wind speed is higher than a preset collection threshold, calculate the difference between the lower limit of the vehicle speed and the ambient wind speed and define it as the lower limit of the vehicle speed; Step 309: Determine the windward distance in response to the lower limit of the vehicle speed; Step 310: Update the bypass path in response to the ambient wind direction, the windward distance, and the charging image.

[0019] By adopting the above technical solution, when the wind force in the area where the vehicle is located is large, by adjusting the driving direction of the vehicle, the efficiency of introducing the wind force when the vehicle is driving against the wind is improved, and the wind force is used to reduce the speed required for the vehicle to travel, thereby improving the stability of the air volume introduced by the air guiding device.

[0020] Optionally, the charging cooling method further includes: Step 311: When in the charging process, determine the moving space in response to the charging image; Step 312: When the moving space is less than a preset driving threshold, determine the cooling area in response to the ambient wind direction and the charging image; Step 313: Determine the cooling position based on the cooling area and a preset driving width; Step 314: Generate a cooling suggestion in response to the cooling position; Step 315: Control a preset prompting device to display the cooling suggestion.

[0021] By adopting the above technical solution, when there is no road around the location of the vehicle for the vehicle to circulate, the area on the windward side where the charging vehicle can dock is found according to the wind direction of the region, and the position where there is a road for the charging vehicle to drive into is screened out from the area, so as to suggest to the driver to drive the vehicle to receive the natural wind from the outside through the prompting device.

[0022] Optionally, the charging and cooling method further includes: Step 316: Determine the regional height in response to the temperature reduction area; Step 317: Determine the wind shielding rate in response to the regional height, environmental wind direction and preset carriage height; Step 318: Determine the temperature reduction efficiency in response to the environmental wind speed and wind shielding rate; Step 319: Determine the temperature reduction lower limit in response to the environmental wind speed; Step 320: Update the temperature reduction area in response to the temperature reduction efficiency and temperature reduction lower limit.

[0023] By adopting the above technical solution, when there are obstacles on the ground, the natural wind blowing towards the charging vehicle is easily blocked by the obstacles on the ground, resulting in a decrease in the temperature reduction effect of the natural wind on the charging vehicle. Select the position with a stronger temperature reduction effect in the area on the windward side where the charging vehicle can dock, so as to improve the accuracy of the temperature reduction suggestion.

[0024] In a second aspect, the present application provides a thermal management system based on a mobile charging vehicle, adopting the following technical solution: A thermal management system based on a mobile charging vehicle, including: An acquisition module, configured to acquire battery temperature, environmental temperature, water tank liquid level, environmental humidity, charging image, environmental wind speed and environmental wind direction; A memory, configured to store any one of the above thermal management methods based on a mobile charging vehicle; A processor, and the program in the memory can be loaded and executed by the processor.

[0025] By adopting the above technical solution, when the energy storage battery overheats during the driving process of the charging vehicle, the air outside the vehicle is introduced into the carriage by using the air guiding device, and the wind speed blown into the carriage is adjusted by adjusting the air guiding area of the air guiding device, so as to reduce the temperature of the energy storage battery by the wind with a relatively high wind speed generated during the high-speed driving of the vehicle, and improve the stability of the use of the mobile charging vehicle.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: When the energy storage battery overheats during the driving of the charging vehicle, a wind guiding device is used to introduce the wind outside the vehicle into the carriage, and the wind speed blown into the carriage is adjusted by adjusting the wind guiding area of the wind guiding device, so as to reduce the temperature of the energy storage battery through the wind with a relatively high wind speed generated during the high-speed driving of the vehicle, and improve the stability of the mobile charging vehicle during use; When the vehicle is driving at a relatively low speed, the wind generated during the driving process is relatively small. At this time, the wind guiding area that needs to be expanded by the wind guiding device to increase the wind speed is likely to be too large. By opening the connection port between the wind guiding device and the water tank, the wind introduced by the wind guiding device is made to blow through the water tank, so as to cool and humidify the wind to improve the cooling effect of the wind and the stability of the mobile charging vehicle during use; When the external humidity is too high, directly introducing the high-humidity wind outside is likely to cause the humidity inside the carriage to be too high, resulting in short circuits in the energy storage battery, charging system, and control system inside the carriage. The high-humidity wind is introduced into the isolation layer inside the carriage that is isolated from the energy storage battery, charging system, and control system through the wind guiding device to reduce the occurrence of short circuits in the energy storage battery, charging system, and control system.

[0027] Figure 1 is a flowchart of a thermal management method based on a mobile charging vehicle. Detailed Embodiments

[0028] In order to make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] Refer to Figure 1 , a thermal management method based on a mobile charging vehicle, includes: Step 100: Collect the battery temperature of the energy storage battery.

[0030] The energy storage battery is the battery used to store electrical energy inside the carriage, and the battery temperature is the temperature value of the energy storage battery. The battery temperature can be collected by a temperature sensor, and the collection method of the battery temperature is selected by the staff according to the actual situation and will not be elaborated here.

[0031] Step 101: When the battery temperature is higher than the preset working temperature, determine the temperature difference in response to the battery temperature and the preset working temperature, and collect the ambient temperature of the charging vehicle.

[0032] The operating temperature refers to the maximum temperature at which the battery stably outputs electrical energy. The operating temperature is selected by the staff according to the actual situation and will not be elaborated here. When the battery temperature is higher than the operating temperature, it means that the temperature of the energy storage battery is too high at this time and cooling is required immediately. The temperature difference refers to the difference value used to show the high-temperature situation 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 value outside the carriage. The ambient temperature can be collected by a temperature sensor. The calculation method of the temperature difference and the collection method of the ambient temperature are selected by the staff according to the actual situation and will not be elaborated here.

[0033] 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.

[0034] The cooling wind speed refers to the wind speed required to cool the high-temperature energy storage battery to a temperature lower than the operating temperature, that is, the wind speed value required to make the temperature difference become 0. The cooling wind speed can be obtained by querying from a temperature relationship table. The temperature relationship table refers to a data table that records different temperature differences, ambient temperatures, and their corresponding cooling wind speeds.

[0035] The driving speed refers to the vehicle speed of the charging vehicle. The driving speed can be directly retrieved from the vehicle-mounted system of the charging vehicle. The retrieval method of the driving speed is selected by the staff according to the actual situation and will not be elaborated here.

[0036] Step 103: Determine the air guiding coefficient in response to the cooling wind speed and the driving speed.

[0037] The isolation layer refers to the space for air flow between the carriage and the energy storage battery. The air guiding device refers to the equipment used to introduce the external wind force into the carriage. The air guiding device generally consists of a pipe with a baffle at one end. The orientation of the pipe is consistent with the driving direction of the vehicle. One end of the pipe is arranged outside the carriage, and the other end of the pipe is connected to the carriage or the isolation layer. The baffle is circumferentially arranged at the end of the pipe outside the carriage. The air volume introduced into the pipe can be adjusted by adjusting the angle of the baffle. The isolation layer and the air guiding device are selected by the staff according to the actual situation and will not be elaborated here.

[0038] The air guiding coefficient refers to the numerical value used to show the air volume that needs to be introduced through the air guiding device. Among them, the wind speed value outside the carriage is shown by the driving speed. Generally, the quotient of the cooling wind speed and the driving speed is used as the air guiding coefficient.

[0039] Step 104: Determine the air guiding area in response to the air guiding coefficient.

[0040] The air guiding area refers to the area value that the air guiding device needs to expand. The air guiding area can be retrieved from an area data table. The area data table refers to a data table that records different air guiding coefficients and their corresponding air guiding areas.

[0041] Step 105: Control the preset air guiding device to open according to the air guiding area to introduce external wind power for battery cooling.

[0042] When the energy storage battery of the charging vehicle overheats during driving, the air guiding device is used to introduce the wind outside the vehicle into the carriage, and the wind speed blown into the carriage is adjusted by adjusting the air guiding area of the air guiding device, so as to reduce the temperature of the energy storage battery through the wind with a large wind speed generated during the high-speed driving of the vehicle, and improve the stability of the mobile charging vehicle.

[0043] A thermal management method based on a mobile charging vehicle further includes: Step 106: When the air guiding area is greater than a preset air guiding threshold, determine the area difference in response to the air guiding area and the preset air guiding threshold.

[0044] The air guiding threshold refers to the maximum area value that the air guiding device can expand. The air guiding threshold is selected by the staff according to the actual situation and will not be elaborated here. That the air guiding area is greater than the air guiding threshold means that the wind speed outside the carriage is too low, and at this time, the wind speed introduced from the outside is not sufficient to effectively reduce the temperature value of the energy storage battery. The area difference is a value used to show the lack of the expanded area of the air guiding device. Generally, the difference between the air guiding area and the air guiding threshold is used as the area difference.

[0045] Step 107: Determine the wind speed difference in response to the area difference.

[0046] The wind speed difference is a value used to show the lack of the external wind speed. The wind speed difference can be queried from the wind difference relationship table. The wind difference relationship table is a data table that records different area differences and their corresponding wind speed differences.

[0047] Step 108: Determine the humidification rate in response to the wind speed difference, and collect the water tank level in the water tank.

[0048] The water tank refers to a container fixed on the charging vehicle and used to store clean water. The water tank is respectively connected to the pipelines of the isolation layer and the air guiding device, and the connection ports of the water tank with the pipelines of the isolation layer and the air guiding device are both located above the water tank to reduce the situation that the liquid water in the water tank flows out from the connection ports. Valves are arranged on the connection ports to control the opening and closing of the connection ports. The water tank is selected by the staff according to the actual situation and will not be elaborated here.

[0049] The humidification rate is the rate of increasing the humidity of the wind power required to make up for the wind speed difference. The humidification rate can be queried from the humidification relationship table. The humidification relationship table is a data table that records different wind speed differences and their corresponding humidification rates.

[0050] The water tank level refers to the water level of the liquid water in the water tank. The water tank level can be collected by a liquid level sensor. The collection method of the water tank level is selected by the staff according to the actual situation and will not be elaborated here.

[0051] Step 109: Determine the evaporation rate in response to the water tank level and a preset air guiding threshold.

[0052] The evaporation rate refers to the rate at which the liquid water in the water tank evaporates, that is, the humidification rate of the water tank for the air flowing through the pipeline of the air guiding device. The higher the water tank level and the larger the air guiding threshold, the greater the evaporation rate. The evaporation rate can be queried from the evaporation relationship table, which is a data table recording different water tank levels, air guiding thresholds, and their corresponding evaporation rates.

[0053] Step 110: Determine the opening coefficient in response to the humidification rate and the evaporation rate.

[0054] The opening coefficient refers to the numerical value of the opening size of the valve used to show the connection condition of the connection port between the water tank and the pipeline of the air guiding device. Generally, the quotient of the humidification rate and the evaporation rate is calculated as the opening coefficient.

[0055] Step 111: Determine the humidification area in response to the opening coefficient.

[0056] The humidification area refers to the opening area of the valve that controls the connection condition of the connection port between the water tank and the pipeline of the air guiding device. The larger the opening coefficient, the larger the required humidification area. The humidification area can be queried from the opening relationship table, which is a data table recording different opening coefficients and their corresponding humidification areas.

[0057] Step 112: Control the preset water tank to open the connection port communicating with the preset air guiding device according to the humidification area.

[0058] When the vehicle is traveling at a low speed, the wind generated during the driving process is small. At this time, in order to increase the wind speed, the air guiding area that the air guiding device needs to expand is likely to be too large. By opening the connection port between the air guiding device and the water tank, the air introduced by the air guiding device can blow through the water tank, thereby cooling and humidifying the air to improve the cooling effect of the air and enhance the stability of the mobile charging vehicle.

[0059] The water collection method includes: Step 200: When the battery temperature is higher than the preset operating temperature, collect the ambient humidity.

[0060] The ambient humidity refers to the absolute humidity value at the location where the charging vehicle is located. The ambient humidity can be collected by a humidity sensor set outside the carriage. The collection method of the ambient humidity is selected by the staff according to the actual situation and will not be elaborated here.

[0061] Step 201: When the ambient humidity is higher than the preset water collection threshold, determine the heat absorption rate in response to the ambient humidity and the temperature difference.

[0062] 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.

[0063] Step 202: Determine the heat absorption air volume in response to the heat absorption rate.

[0064] 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.

[0065] Step 203: Determine a heat absorption area in response to the heat absorption air volume.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] Water harvesting methods also include: 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.

[0070] 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.

[0071] Step 206: When the dew point temperature is not greater than the preset water collection temperature, determine the water collection temperature difference in response to the dew point temperature and the preset water collection temperature.

[0072] The water collection plate refers to a device fixed in the water tank for driving the condensation of water droplets from water vapor in the air. Generally, a metal plate is used. The water collection plate is correspondingly arranged at the communication port between the water tank and the isolation layer, and the water collection plate is generally vertically arranged to facilitate the water droplets condensed on the water collection plate to flow into the water tank. The water collection plate is selected by the staff according to the actual situation and will not be elaborated here.

[0073] The water collection temperature refers to the temperature value of the water collection plate at normal temperature. The water collection temperature is selected by the staff according to the actual situation and will not be elaborated here. That the dew point temperature is not greater than the water collection temperature indicates that when the outside air contacts the water collection plate, water droplets are likely to condense. The water collection temperature difference is a value used to show the ease of water droplet condensation on the water collection plate. Generally, the difference between the dew point temperature and the water collection temperature is calculated as the water collection temperature difference. The larger the water collection temperature difference, the easier the water droplets are to condense.

[0074] Step 207: Determine the water collection rate in response to the water collection temperature difference.

[0075] The water collection rate refers to the maximum speed value at which water droplets can be fully condensed when the air flow passes through the water collection plate. The larger the water collection temperature difference, the larger the water collection rate. The water collection rate can be queried from the rate relationship table, which is a data table recording different water collection temperature differences and their corresponding water collection rates.

[0076] Step 208: Determine the water collection area in response to the water collection rate and the heat absorption air volume.

[0077] The water collection area refers to the opening and closing size of the valve that controls the communication situation between the water tank and the isolation 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. Preferably, the average value of the water collection rate and the heat absorption air volume is used as the water collection air volume. Then, the water collection area corresponding to the water collection air volume is queried from the water collection relationship table, which is a data table recording 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.

[0078] Step 209: Control the preset air guiding device to open according to the water collection area to introduce the wind in the isolation layer onto the water collection plate preset in the water tank.

[0079] The higher the humidity of the outside world, the higher the dew point temperature. By guiding the high-humidity wind into the water collection plate in the water tank through the air guiding device, the high-temperature and high-humidity wind can be condensed into water droplets by the relatively low-temperature water collection plate, and the water droplets are driven to enter the water tank along the water collection plate, thereby maintaining the water volume in the water tank.

[0080] The water collection method further includes: Step 210: When the water level in the water tank is lower than the preset cooling threshold, retrieve the driving route.

[0081] The cooling threshold refers to the minimum liquid level value that ensures the cooling effect of the water tank. The cooling threshold is selected by the staff according to the actual situation and will not be elaborated here. When the water tank liquid level is lower than the cooling threshold, it means that the water level in the water tank is too low, and at this time, water needs to be replenished as soon as possible. The driving route refers to a dataset containing information such as the location of the charging vehicle, the driving end point, and the driving speed. The driving route can be directly retrieved from the in-vehicle system of the charging vehicle. The method for retrieving the driving route is selected by the staff according to the actual situation and will not be elaborated here.

[0082] Step 211: Respond to the retrieved regional humidity of the driving route and respond to the retrieved regional route of the driving route.

[0083] 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. The meteorological data can be retrieved from the local meteorological station. The method for retrieving regional humidity is selected by the staff according to the actual situation and will not be elaborated here.

[0084] Regional route refers to the traffic route 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 traffic data. The traffic data can be retrieved from the navigation system. The method for retrieving the regional route is selected by the staff according to the actual situation and will not be elaborated here.

[0085] Step 212: Determine the water collection route in response to the regional humidity and regional route.

[0086] 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 end point. First, the driving end point can be retrieved from the driving route, and then all the routes from the location of the charging vehicle to the driving end point can be planned by the regional route. Finally, the humidity contained in each route can be calculated by combining 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.

[0087] Step 213: Generate a water collection suggestion in response to the water collection route.

[0088] The prompting device refers to the device used to display information to the driver, usually a display screen. The prompting device is selected by the staff according to the actual situation and will not be elaborated here. The water collection suggestion refers to the dataset that displays the water collection route to the driver through the prompting device. The method for generating the water collection suggestion is common knowledge in the field and will not be elaborated here.

[0089] Step 214: Control the preset prompting device to display the water collection suggestion.

[0090] When the water level in the water tank is too low, retrieve the meteorological data and traffic route data of the area where the vehicle is located, so as to plan a driving route with sufficient environmental water vapor, thereby reducing the loss of water volume in the water tank.

[0091] The charging cooling method includes: Step 300: When the driving speed is lower than the preset air guiding threshold, retrieve the charging information of the battery.

[0092] The charging information refers to the data including the input and output of electric energy of the energy storage battery, which can be retrieved from the control system in the carriage. The retrieval method of the charging information is selected by the staff according to the actual situation and will not be elaborated here.

[0093] Step 301: Judge whether it is in the charging process according to the charging information.

[0094] Being in the charging process means that the battery is outputting or inputting electric energy. The judgment method of the charging process is selected by the staff according to the actual situation and will not be elaborated here.

[0095] Step 302: When in the charging process, determine the lower limit of the vehicle speed in response to the cooling wind speed and the preset air guiding threshold.

[0096] The lower limit of the vehicle speed refers to the minimum external wind speed value required for the air guiding device to expand to the maximum to form an air flow with a cooling wind speed, that is, the minimum speed value required for the vehicle to travel. The air guiding coefficient corresponding to the air guiding threshold can be queried from the area data table, and then the quotient of the cooling wind speed and the air guiding coefficient is calculated as the lower limit of the vehicle speed.

[0097] Step 303: Determine the circumferential radius in response to the lower limit of the vehicle speed and collect the charging image of the charging vehicle.

[0098] The circumferential radius refers to the radius value of the charging vehicle moving in a circular motion around the charging or being charged device. By adjusting the circumferential radius to maintain the angular velocity during the vehicle driving process, the larger the lower limit of the vehicle speed, the larger the circumferential radius. The calculation method of the circumferential radius is common knowledge in the field and will not be elaborated here. The charging image refers to the picture of the area where the charging vehicle is located. The charging image can be collected through the camera on the charging vehicle. The collection method of the charging image is selected by the staff according to the actual situation and will not be elaborated here.

[0099] Step 304: Determine the circumferential path in response to the circumferential radius and the charging image.

[0100] The circumferential path refers to the route of the charging vehicle moving in a circular motion around the charging or being charged device. The determination method of the circumferential path is common knowledge in the field and will not be elaborated here.

[0101] Step 305: Generate a driving suggestion in response to the circumferential path.

[0102] The driving suggestion refers to a dataset that shows a detour route to the driver through a prompting device. The method for generating the driving suggestion is common knowledge to those skilled in the art and will not be elaborated here.

[0103] Step 306: Control the preset prompting device to display the driving suggestion.

[0104] When the driving speed of the vehicle is too low, it is difficult to form a relatively large wind speed, and heat is easily continuously generated during the charging process of the battery. At this time, a route for the vehicle to continuously drive to generate a stable wind force is planned through the prompting device, so as to generate a stable wind force through driving.

[0105] The charging cooling method further includes: Step 307: When in the charging process, collect the ambient wind speed and ambient wind direction.

[0106] 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 set on the carriage. The collection methods of the ambient wind speed and ambient wind direction are selected by the staff according to the actual situation and will not be elaborated here.

[0107] Step 308: When the ambient wind speed is higher than a preset collection threshold, calculate the difference between the lower limit of the vehicle speed and the ambient wind speed and define it as the lower limit of the vehicle speed.

[0108] The collection threshold refers to the minimum wind speed value that can be introduced through the wind guiding device. The collection threshold is selected by the staff according to the actual situation and will not be elaborated here. The ambient wind speed being higher than the collection threshold represents that the wind speed of the environment that can be collected, that is, the wind force of the environment can be used to reduce the speed value that the charging vehicle needs to travel.

[0109] Step 309: Determine the windward distance in response to the lower limit of the vehicle speed.

[0110] The windward distance refers to the position point farthest from the charging device or the device being charged in the route of the vehicle's travel. The detour radius can be calculated from the lower limit of the vehicle speed, and then the length value of the route traveled by the charging vehicle can be calculated from the detour radius. Finally, the quotient of the length value and 4 is calculated as the windward distance.

[0111] Step 310: Update the detour route in response to the ambient wind direction, windward distance, and charging image.

[0112] When the wind force at the location where the charging vehicle is located is relatively large, the reciprocating route between the first position point of the upwind distance along the ambient wind direction from the charging device or the device being charged to the second position point of the upwind distance along the reverse direction of the ambient wind direction from the charging device or the device being charged is used as a new detour path to improve the efficiency of the air volume introduced by the air guiding device when the charging vehicle is traveling against the wind, thereby reducing the speed required for the vehicle to travel by utilizing the wind force, and further improving the stability of the air volume introduced by the air guiding device.

[0113] The charging and cooling method further includes: Step 311: When in the charging process, determine the moving space in response to the charging image.

[0114] The moving space refers to the area value where the charging vehicle can reciprocate in the area where the charging vehicle is located. The moving space can be identified through image recognition technology. The method for identifying the moving space is common knowledge for those skilled in the art and will not be elaborated here.

[0115] Step 312: When the moving space is less than a preset driving threshold, determine the cooling area in response to the ambient wind direction and the charging image.

[0116] The driving threshold refers to the minimum area value for the charging vehicle to reciprocate. The driving threshold is selected by the staff according to the actual situation and will not be elaborated here. The moving space being less than the driving threshold means that there is no space in the area where the charging vehicle is located for the charging vehicle to reciprocate. The cooling area refers to the area with a higher cooling effect. Generally, the area in the charging image located in the reverse direction of the ambient wind direction of the charging vehicle is used as the cooling area. The method for determining the cooling area is common knowledge for those skilled in the art and will not be elaborated here.

[0117] Step 313: Determine the cooling position based on the cooling area and a preset driving width.

[0118] The driving width refers to the minimum width value of the road that the charging vehicle can pass through, that is, the body width of the charging vehicle. The driving width is selected by the staff according to the actual situation and will not be elaborated here. The cooling position refers to the position point in the cooling area that the charging vehicle can reach. The road and its width can be identified from the charging image through image recognition technology, and then the roads with a width greater than the driving width in the road are screened out, and the position in the road that is 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 for those skilled in the art and will not be elaborated here.

[0119] Step 314: Generate a cooling suggestion in response to the cooling position.

[0120] The cooling suggestion refers to a data set used to display the cooling position and the route to reach the cooling position to the driver through a prompting device. The method for generating the cooling suggestion is common knowledge for those skilled in the art and will not be elaborated here.

[0121] Step 315: Control a preset prompting device to display the cooling suggestion.

[0122] When there is no road around the location of the vehicle for the vehicle to circulate, find the area on the windward side where the charging vehicle can park according to the wind direction of the region, and screen out the positions in the area where there is a road for the charging vehicle to drive into, so as to suggest to the driver to drive the vehicle to receive the natural wind from the outside through the prompting device.

[0123] The charging cooling method further includes: Step 316: Determine the regional height in response to the cooling area.

[0124] The regional height refers to the height values of each point in the cooling area. The regional height can be identified by image recognition technology. The method for identifying the regional height is common knowledge for those skilled in the art and will not be elaborated here.

[0125] Step 317: Determine the wind shielding rate in response to the regional height, environmental wind direction, and a preset carriage height.

[0126] The carriage height refers to the highest height value of the charging vehicle carriage. The carriage height is selected by the staff according to the actual situation and will not be elaborated here. The wind shielding rate refers to the ratio of the wind blocked at each position point in the cooling area. The quotient of the regional height and the carriage height in the opposite direction of the environmental wind direction at each position point in the cooling area can be calculated as the wind shielding rate. The method for calculating the wind shielding rate is common knowledge for those skilled in the art and will not be elaborated here.

[0127] Step 318: Determine the cooling efficiency in response to the environmental wind speed and the wind shielding rate.

[0128] The cooling efficiency refers to the value showing the cooling effect of the outside wind. Generally, the product of the environmental wind speed and the wind shielding rate is calculated as the cooling efficiency.

[0129] Step 319: Determine the cooling lower limit in response to the environmental wind speed.

[0130] The cooling lower limit refers to the value showing the cooling effect of the wind at the location of the charging vehicle. The method for determining the cooling lower limit is common knowledge for those skilled in the art and will not be elaborated here.

[0131] Step 320: Update the cooling area in response to the cooling efficiency and the cooling lower limit.

[0132] When there are obstacles on the ground, it is easy to cause the natural wind blowing towards the charging vehicle to be blocked by the obstacles on the ground, resulting in a decrease in the cooling effect of the natural wind on the charging vehicle. Screen out the areas in the cooling area where the cooling efficiency is lower than the cooling lower limit, so as to select the positions with stronger cooling effects in the cooling area, thereby improving the accuracy of the cooling suggestion.
