Description

Technical Field

[0001] The present invention relates to the technical field of power supply control for vehicle-mounted refrigerators, and in particular to a power supply control method and device for a vehicle-mounted refrigerator. Background Art

[0002] With the popularity of new energy vehicles and consumers' increasing demand for travel comfort, car refrigerators are becoming more and more popular in the market as an accessory to enhance driving experience. Car refrigerators can not only provide cold drinks and fresh food for users on long-distance trips, but also bring a touch of coolness to passengers in the hot summer. However, the energy consumption of car refrigerators has always been one of the key factors restricting their performance.

[0003] The existing publication number CN116749768A discloses a power supply control method, device and electronic device for a vehicle refrigerator, wherein the method includes: obtaining refrigerator setting information of a vehicle, the refrigerator setting information including off-vehicle setting information; the off-vehicle setting information is used to indicate the off-vehicle power supply mode of the vehicle refrigerator; obtaining the vehicle status of the vehicle; the vehicle status includes: a first vehicle status and a second vehicle status; in the first vehicle status, the vehicle's battery does not supply power to the motor; in the second vehicle status, the vehicle's battery supplies power to the motor; when the vehicle switches from the second vehicle status to the first vehicle status, according to the off-vehicle power supply mode, controlling whether the battery supplies power to the vehicle refrigerator, thereby being able to meet different usage requirements of the vehicle refrigerator by objects in the vehicle through different off-vehicle setting information, thereby improving the power supply control efficiency of the vehicle refrigerator.

[0004] Although the existing technology realizes the control of the power supply of the vehicle refrigerator, it cannot reasonably plan the power supply of the vehicle refrigerator according to the specific driving route and battery capacity, and cannot plan the power supply of the refrigerator in advance according to the user's usage habits. Therefore, we propose a method and device for controlling the power supply of the vehicle refrigerator. Summary of the invention

[0005] The purpose of the present invention is to provide a method and device for controlling power supply of a vehicle refrigerator, so as to solve the problem in the prior art that the power supply of the vehicle refrigerator cannot be reasonably planned according to the specific driving route and battery capacity, and the refrigerator power supply cannot be planned in advance according to the user's usage habits.

[0006] To achieve the above object, the present invention provides the following technical solution: a method for controlling power supply of a vehicle refrigerator, comprising the following steps:

[0007] S1. Obtain the itinerary plan: departure location, destination, driving route, whether charging is planned during the journey, and estimated driving time;

[0008] S2. Battery capacity acquisition: obtain the remaining battery capacity;

[0009] S3, determining whether the battery capacity supports the planned trip;

[0010] S4. If S3 determines that the planned trip is not supported, the refrigerator is not turned on; if S3 determines that the planned trip is supported, it calculates whether the power at the end of the trip is lower than the threshold;

[0011] S5. If the calculation result of S4 is lower than the threshold, the refrigerator is not turned on; if the calculation result of S4 is higher than the threshold, the working time of the refrigerator at the highest power is calculated;

[0012] S6. If the working time calculated by S5 is greater than the driving time, the refrigerator can be turned on at will; if the working time calculated by S5 is less than the driving time, the working time of the refrigerator at the lowest power is calculated;

[0013] S7. If the working time calculated by S6 is greater than the driving time, the refrigerator adopts a power supply method of first high power and then low power; if the working time calculated by S6 is less than the driving time, the refrigerator adopts a power supply method of first low power and then off.

[0014] Preferably, if charging is performed midway in S1, the destination is calculated based on the planned charging address, and the estimated driving time is also based on the time to arrive at the charging address.

[0015] Preferably, after charging is completed, the starting point automatically becomes the charging address, and the destination is the originally planned destination.

[0016] Preferably, the method also includes inputting the weight of the placed item and the approximate temperature of the placed item, and estimating the amount of electricity required to cool the item to the desired temperature based on the weight and initial temperature of the item.

[0017] Preferably, it also includes the number of times the refrigerator door is opened per unit driving time and per unit driving frequency, and estimates the amount of electricity required to open the refrigerator door and cool it down to the required temperature each time.

[0018] Preferably, it also includes big data prediction, dynamically adjusting the power supply plan according to driving habits and environmental factors. If big data predicts that the car owner will buy food for refrigeration during a certain period of time, the power supply system will reserve enough electricity for the refrigerator in advance.

[0019] A vehicle refrigerator power supply control device comprises a travel acquisition module, a power acquisition module, a comparison module, a power selection module, a switch module and a control module;

[0020] The trip acquisition module is used to obtain the departure location, destination, driving route, whether charging is planned during the trip, and the estimated driving time;

[0021] The power acquisition module is used to obtain the remaining capacity of the battery;

[0022] The comparison module is used for comparing the amount of electricity and the time;

[0023] The power selection module is used to select the working power of the refrigerator;

[0024] The switch module is used to control the switch of the refrigerator;

[0025] The control module is used to control each module.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. Based on the itinerary plan and battery capacity, determine whether the battery capacity supports the planned itinerary; if the battery capacity determines that the planned itinerary is not supported, the refrigerator will not be turned on; if the battery capacity determines that the planned itinerary is supported, calculate whether the power at the end of the itinerary is lower than the threshold; if the remaining power calculation result is lower than the threshold, the refrigerator will not be turned on; it can be used to ensure the vehicle's driving power.

[0028] 2. If the working time of the remaining power is greater than the driving time, the refrigerator can be set to turn on at will; if the working time of the remaining power is less than the driving time, the working time of the refrigerator at the lowest power is calculated; if the calculated working time is greater than the driving time, the refrigerator adopts a power supply method of first high power and then low power; if the calculated working time is less than the driving time, the refrigerator adopts a power supply method of first low power and then shut down; thus, the refrigerator can be powered very reasonably.

[0029] 3. Input the weight of the items placed and the approximate temperature of the items, and estimate the amount of electricity required to cool down to the required temperature based on the weight of the items and the initial temperature; the number of times the refrigerator door is opened per unit driving time and per unit driving number, and estimate the amount of electricity required to cool down to the required temperature each time the refrigerator door is opened; dynamically adjust the power supply plan based on driving habits and environmental factors. If big data predicts that the owner will buy food for refrigeration during a certain period of time, the power supply system will reserve enough electricity for the refrigerator in advance. The power supply of the refrigerator can be planned in advance based on the user's usage habits. BRIEF DESCRIPTION OF THE DRAWINGS
