[0045] The present application embodiment provides a charging station availability guarantee method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the charging station availability assurance method of the present application.

[0046] In this embodiment, the charging station availability assurance method includes steps S10 to S50.

[0047] S10: Obtaining the energy consumption rate of the battery during the driving of the vehicle.

[0048] S20: Obtain the current planned path information of the vehicle.

[0049] S30: Calculate the first position that the vehicle will reach when the battery power drops to a first preset battery power according to the energy consumption rate of the vehicle and the current planned path information of the vehicle.

[0050] S40: Search for charging stations according to the first location to obtain charging station search results.

[0051] S50: Pushing a driving plan to the user based on the search results.

[0052] It should be noted that the energy consumption rate refers to the amount of energy consumed by a vehicle traveling a unit distance (such as kilometers, miles, etc.).

[0053] It should be noted that planning path information refers to the information of one or more optimal paths calculated by an algorithm or method based on the target location and the starting location in a given environment or map. This path can be a sequence of points or a curve connecting the starting point and the end point, aiming to enable a mobile object (such as a robot, a vehicle, etc.) to reach the destination efficiently and without collision.

[0054] As you can understand, planning path information usually includes the following key elements:

[0055] Starting position: The initial position of the moving object, which is the starting point of path planning.

[0056] Target position: The final position that the moving object needs to reach, which is the end point of path planning.

[0057] Path points: A sequence of intermediate points connecting the starting position and the target position, which form the skeleton of the path.

[0058] Path length: The sum of the distances between all points on a path, which is an important indicator for evaluating the quality of a path.

[0059] Obstacle information: information such as the location, shape, and size of obstacles that need to be considered when planning a path to ensure the safety of the path.

[0060] Path optimization indicators: such as shortest time, shortest distance, lowest energy consumption, etc., are used to evaluate the advantages and disadvantages of different paths and select the optimal path.

[0061] It should be noted that the energy consumption rate of the battery during vehicle driving can be obtained by measuring the power consumption per 100 kilometers, calculating the driving speed correlation, operating condition testing method, constant speed testing method, or by recording and analyzing actual driving data. This embodiment does not limit this.

[0062] It should be noted that the method for obtaining the vehicle's current planned path information may be by using a vehicle-mounted GPS device, a mobile phone application, or other methods, which are not limited in this embodiment.

[0063] In this embodiment, the first power level is set to 20% of the power level.

[0064] Understandably, 20% of the power is equivalent to the vehicle entering the low-power zone, which provides a certain redundancy to avoid the risk of sudden power outage.

[0065] Understandably, considering the actual vehicle energy consumption rate and driving conditions, 20% of the power can usually cover a driving distance of tens of kilometers, which is enough to cope with a variety of scenarios such as cities or highways.

[0066] It should be noted that the first electrical quantity can be modified according to actual needs, and this embodiment does not limit this.

[0067] It should be noted that the first position refers to the position reached when the power level drops to a first preset power level.

[0068] It can be understood that a driving plan refers to a series of measures and regulations formulated to ensure the safe, efficient and comfortable driving of vehicles on the road. These measures and regulations cover route planning, vehicle selection, driver training, compliance with traffic regulations, driving speed control, emergency response measures and other aspects.

[0069] As you can understand, driving plans usually include the following key elements:

[0070] Route planning: Select the best driving route based on factors such as destination, traffic flow, road conditions, traffic rules, etc. This includes determining the starting and end points, as well as key nodes along the way and possible detours.

[0071] Vehicle selection: Choose the right vehicle type based on driving needs and environmental conditions. This includes considering factors such as vehicle size, load capacity, fuel efficiency, and safety.

[0072] Traffic regulations compliance: Ensure that drivers strictly comply with traffic regulations during driving, including speed limits, driving directions, traffic lights, etc. This helps maintain road traffic order and ensure driving safety.

[0073] Driving speed control: According to road conditions and traffic rules, the driving speed can be reasonably controlled. This helps to reduce energy consumption, improve driving efficiency, and reduce the possibility of accidents.

[0074] Emergency response measures: Develop emergency response measures, including plans for dealing with traffic accidents, vehicle breakdowns, bad weather, etc. This helps to take quick action in an emergency to ensure the safety of people and vehicles.

[0075] It can be understood that the distance the vehicle will travel when the current power level drops to the first preset power level can be calculated based on the vehicle's energy consumption rate, and the first location reached when the power level drops to the first preset power level can be calculated based on the vehicle's currently planned route information and the distance the vehicle will travel when the current power level drops to the first preset power level.

[0076] It should be noted that the method of searching for charging stations may be through a third-party application, a brand application, or an application launched by a power company, which is not limited in this embodiment.

[0077] It is understandable that after obtaining the charging station search results, it is necessary to provide the user with a driving plan based on the search results, such as navigating to the charging station closest to the first location, or navigating to a suitable location based on the status of the charging station (such as being disabled or all charging piles are occupied and there are no available charging piles), etc. This embodiment does not limit this.

[0078] In specific implementation, the energy consumption rate of the battery during vehicle driving is obtained; the current planned route information of the vehicle is obtained; the first position reached when the battery power of the vehicle drops to a first preset power level is calculated based on the energy consumption rate of the vehicle and the current planned route information of the vehicle; a charging station is searched based on the first position to obtain the charging station search result; and a driving plan is pushed to the user based on the search result.

[0079] This embodiment pushes a driving plan to the user based on the vehicle energy consumption rate and charging station data, reduces the risk of long-distance driving due to unavailable charging stations, and improves the practicality and user experience of electric vehicles.

[0080] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the first embodiment can refer to the above introduction, and will not be repeated in the following. Figure 2 , Figure 2 This is a flow chart of the second embodiment of the charging station availability assurance method of the present application.

[0081] In this embodiment, the steps of step S10 specifically include steps S101 to S103.

[0082] S101: Obtaining the initial power of the vehicle battery.

[0083] S102: When the vehicle power level drops to a second preset power level, obtaining a second mileage traveled from the initial power level to the second preset power level.

[0084] S103: Calculate the energy consumption rate of the vehicle according to the initial power, the second preset power and the second mileage.

[0085] It can be understood that the initial power level of the vehicle battery refers to the power level of the vehicle battery when it is used for the first time after being fully charged or when it leaves the factory.

[0086] In this embodiment, the second preset power level is set to 50% power level.

[0087] It is understandable that, on the one hand, 50% power can provide the vehicle with a larger remaining driving distance, and even if some charging stations are unavailable in the future, there is still enough time to make adjustments; on the other hand, from 100% to 50% power range, the energy consumption rate changes relatively smoothly, which helps to more accurately predict future energy consumption.

[0088] It can be understood that the energy consumption rate ECR of a vehicle from the initial power to 50% power can be calculated by the following formula:

[0089]

[0090] Among them, E initial Indicates the initial charge of the vehicle (e.g. 100%), E current represents the second preset power (such as 50%), dtraveled represents the mileage when the vehicle's power drops from the initial power to the second preset power; the calculated energy consumption rate ECR can be used to predict the mileage d when the vehicle's power drops from the second preset power to the first preset power expected :

[0091] Among them, E future The first preset power level (eg, 20%).

[0092] In specific implementation, the initial power of the vehicle battery is obtained; when the vehicle power drops to a second preset power, the second mileage traveled from the initial power to the second preset power is obtained; the energy consumption rate of the vehicle is calculated based on the initial power, the second preset power and the second mileage. The current planned route information of the vehicle is obtained; the first location reached when the vehicle power drops to the first preset power is calculated based on the vehicle energy consumption rate and the current planned route information of the vehicle; a charging station is searched based on the first location to obtain a charging station search result; and a driving plan is pushed to the user based on the search result.

[0093] It can be understood that the second mileage refers to the mileage traveled from the initial power level to the second preset power level.

[0094] This embodiment calculates the energy consumption rate of the vehicle according to the initial power, the second preset power and the second mileage traveled from the initial power to the second preset power, so as to more accurately predict future energy consumption.

[0095] Based on the second embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those of the second embodiment can be referred to the above introduction, and will not be repeated in the following. Figure 3 , Figure 3 This is a flow chart of the third embodiment of the charging station availability assurance method of the present application.

[0096] In this embodiment, the steps of step S30 specifically include steps S301 to S302; the steps of step S40 specifically include steps S401 to S402; and the steps of step S50 specifically include steps S501 to S502.

[0097] S301: Calculate a first mileage traveled when the battery level of the vehicle drops to a first preset battery level based on the energy consumption rate.

[0098] S302: Determine a first location to be reached when the battery power of the vehicle drops to a first preset battery power according to the planned route information and the first mileage.

[0099] S401: Obtaining the effective radius of the vehicle searching for a charging station.

[0100] S402: Searching for charging stations according to the effective radius with the first location as the center, and obtaining charging station search results.

[0101] S501: Determine a target charging station for charging the vehicle battery according to the search result.

[0102] S502: Determine a driving plan for the vehicle according to the target charging station, and push the driving plan.

[0103] In this embodiment, step S501 specifically also includes steps S5011 to S5012.

[0104] S5011: If the search result indicates that there is a charging station within the effective radius of the first location, taking the charging station closest to the first location as the target charging station;

[0105] S5012: If the search result indicates that there is no charging station within the effective radius of the first position, the charging station closest to the current position is used as the target charging station.

[0106] It can be understood that the effective radius refers to the effective range of the vehicle searching for a charging station. If the charging station is beyond the effective radius from the first position, the charging station is determined to be an invalid charging station. If the charging station is within the effective radius from the first position, the charging station is determined to be a valid charging station.

[0107] It should be noted that the effective radius can be modified according to actual needs.

[0108] In this embodiment, the effective radius is set to 5 km.

[0109] Understandably, the 5km range provides the vehicle with appropriate safety margins, ensuring that when the battery drops to 20%, the vehicle still has enough driving distance to cope with slight deviations in the location of charging stations. If the range is reduced, some charging stations that are slightly off the path but still feasible may be missed; if the range is increased, unnecessary detours may be triggered, increasing the risk of running out of power.

[0110] It is understandable that when the vehicle's battery drops to 50%, the vehicle will automatically trigger a cloud request to calculate whether the vehicle can find a suitable charging station when the battery drops to 20%. The expected mileage in the future is calculated according to the above formula, and then a charging station search is performed based on the mileage, with a search range of 5km.

[0111] Furthermore, if the search result shows that there is a charging station within the effective radius of the first location, the charging station closest to the first location is used as the target charging station to ensure that the vehicle can be charged before the battery is exhausted, reducing the user's anxiety about battery life. If the search result shows that there is no charging station within the effective radius of the first location, the charging station closest to the current location is used as the target charging station to prevent the owner from being unable to recharge in time before the battery is exhausted due to the subsequent failure to find an available charging station.

[0112] In a specific implementation, the first mileage traveled when the battery power of the vehicle drops to a first preset power level is calculated according to the energy consumption rate; the first position reached when the battery power of the vehicle drops to the first preset power level is determined according to the planned route information and the first mileage; the effective radius of the vehicle searching for a charging station is obtained; with the first position as the center, charging stations are searched according to the effective radius to obtain a charging station search result; if the search result shows that a charging station exists within the effective radius of the first position, the charging station closest to the first position is used as the target charging station; if the search result shows that there is no charging station within the effective radius of the first position, the charging station closest to the current position is used as the target charging station.

[0113] By setting an effective range, this embodiment can further ensure that the vehicle can be charged before the battery is exhausted, thereby reducing the user's battery anxiety.

[0114] In addition, to achieve the above-mentioned purpose, the present application also proposes a charging station availability guarantee device, which includes: an information interaction module, a calculation module, a search module and a processing module.

[0115] The information interaction module is used to obtain the energy consumption rate of the battery and the current planned path information of the vehicle during the driving process of the vehicle;

[0116] The calculation module is used to calculate the first position that the vehicle will reach when the power of the vehicle drops to a first preset power according to the energy consumption rate of the vehicle and the current planned path information of the vehicle;

[0117] The search module is used to search for charging station information according to the first location;

[0118] The processing module is used to plan a driving plan based on the search results;

[0119] The information interaction module is also used to push the driving plan to the user.
