Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application.
The following first describes a system architecture and application scenarios that may be involved in the embodiments of the present application.
Referring to fig. 1, a schematic block diagram of a structure of an electric vehicle charging system provided in an embodiment of the present application includes a charging station 11, an electric vehicle 12, a user terminal device 13, and a server 14, where the charging station includes a plurality of charging piles, and each charging pile includes a plurality of charging sockets. Corresponding APP can be installed in the user terminal equipment to realize corresponding functions in the charging process, such as code scanning payment, charging order generation, charging order uploading and the like. The user terminal device may be, but is not limited to, a mobile phone, a smart wearable device, a tablet computer, or the like. The electric vehicle may be any type of electric vehicle, for example, an electric two-wheeled vehicle or an electric four-wheeled vehicle.
The electric vehicle charging process based on the system can comprise the following steps: after a user drives the electric vehicle to arrive at a charging station, scanning the two-dimensional code on the charging pile through a mobile phone to generate a charging order; after the corresponding socket of the charging pile supplies power, a user can connect the electric vehicle to the charging pile through the plug and the power adapter to start charging the electric vehicle; when the charging time reaches the preset charging time, the charging fee reaches the prepayment fee or the electric vehicle is full, the charging plug can be unplugged, and a charging process is completed.
In the charging process of the electric vehicle, the charging pile can record the charging data of the electric vehicle in real time, report the charging data to the charging pile management platform, and store the charging data to the database. The charging data generally includes charging current data, charging voltage data, charging power data, and the like. In addition, the charging order data of the user can be uploaded to the server for storage.
Based on the system architecture shown in fig. 1, the server may analyze charging data corresponding to a certain charging order of a certain user through the recorded data to determine whether the battery of the electric vehicle of the user is aged, and if it is analyzed that the aging phenomenon of the battery of the electric vehicle of the certain user occurs, prompt information may be generated to warn the user about the health condition of the battery of the electric vehicle. For example, after a user completes a charging order, the server acquires telemetering data corresponding to a charging pile according to the charging order of the user so as to obtain charging current data of the electric vehicle of the user during the current charging, and then judges whether the charging current data meets a preset condition, if so, the battery of the user is judged to be aged; and then, the server generates aging prompt information, the aging prompt information is sent to a user mobile phone, and the aging prompt information is displayed to the user through the user mobile phone APP, so that the user can timely know the battery health condition of the electric vehicle.
Of course, the embodiments of the present application may not be based on the above system architecture or application scenario, and the purposes of the embodiments of the present application may also be achieved.
The technical solutions provided in the embodiments of the present application will be described below by specific embodiments.
Referring to fig. 2, a schematic flow chart of a method for identifying battery aging of an electric vehicle according to an embodiment of the present application may include the following steps:
and step S201, acquiring charging data of the electric vehicle.
It should be noted that the charging data generally refers to data of a charging process of the electric vehicle. Based on the system architecture or the application scenario of fig. 1, a charging process refers to a process corresponding to one charging order, that is, the charging data is charging data corresponding to one charging order, and at this time, the charging data is reported by the charging pile. In other words, in some embodiments, the telemetry data uploaded by the corresponding charging pile may be acquired through charging order data of a user of the electric vehicle, where the telemetry data includes charging data. The charging data includes, but is not limited to, charging current data, charging voltage data, charging power data and the like, and the charging order data includes information such as a user unique identifier, charging start time, charging end time, charging pile number and the like. Specifically, after a user completes a charging order, the server searches telemetering data reported by a corresponding charging pile from a database according to information of a user unique identifier, charging start time, charging end time, a charging pile number and the like in the charging order, and then searches charging data corresponding to the user unique identifier, the charging start time, the charging end time and the like from the telemetering data so as to obtain charging data corresponding to the current charging of the user.
Of course, the technical solution of the embodiment of the present application may not be applied to the system architecture or the application scenario shown in fig. 1, and in this case, the charging data may refer to charging data recorded when the electric vehicle is charged by a certain charging device.
Step S202, determining whether the charging data meets a preset condition.
Wherein the preset condition comprises at least one of the following conditions:
the first item: the charging time is less than or equal to the charging time threshold;
the second term is: the oscillation number is greater than or equal to an oscillation number threshold value, and the average voltage is less than a preset threshold value;
the third item: the charging data has a second stage, the duration time of the second stage is greater than or equal to a first preset time threshold, the starting point of the second stage is smaller than a preset time point, and the total charging amount of the charging process corresponding to the charging data is smaller than a preset charging amount threshold;
the fourth item: the charging data has a second stage, the duration time of the second stage is greater than or equal to a first preset duration threshold and less than or equal to a second preset duration threshold, and the current of the second stage is less than a preset current threshold;
the fifth item: the total power of the charging data is smaller than a first preset power threshold value and the average power is smaller than a second preset power threshold value.
It is understood that the charging period may be calculated by the charging start time and the charging end time. When the charging time period is less than or equal to the charging time period threshold, it may be determined that the charging time is too short. The charging duration threshold is an empirical threshold, for example, the charging duration threshold is 5 hours.
In the embodiment of the present application, the oscillation may be defined as: the number of rising times is more than 4 and the number of falling times is more than 4 in a certain time period. Wherein, the rising amplitude is greater than 0.49 and defined as a rise, and the falling amplitude is greater than 0.49 and defined as a fall. And counting the current oscillation times in the charging data according to the oscillation definition and the charging current data in the charging data. In the charging process of the electric vehicle, the charging voltage is generally constant, the charging current data can change along with the change of the charging time, and the oscillation mainly aims at the charging current data.
The oscillation number threshold and the preset threshold are empirical thresholds. In this embodiment, the oscillation number threshold may be 5, and the preset threshold may be an electricity consumption threshold for one hour, where the threshold is 0.05. In specific application, after the average voltage is calculated according to charging voltage data, the average voltage and the unit of the preset threshold are unified, and then the average voltage and the unit of the preset threshold are compared. When the oscillation quantity of the charging data is greater than or equal to the oscillation quantity threshold and the average voltage is less than the preset threshold, it can be determined that the charging amount is small and the charging is oscillating.
It is understood that the complete charging process of the electric vehicle generally includes a first stage, a second stage and a third stage, wherein the first stage is a steady charging of current and voltage, the second stage is a descending charging with a constant voltage and a small current, and the third stage is a trickle charging with a constant voltage and a small current until the current voltage is zero.
The duration of the second phase may be calculated by the time of the end point of the first phase and the time of the end point of the second phase. In this embodiment of the application, the first preset duration threshold may be specifically 0.5 h. The predetermined time may be 79min, for example. The preset charge amount threshold value may be, for example, 0.59508C. The second preset time threshold may be, for example, 1.5h, and the preset current threshold is 0.16A. The first preset power threshold may be, for example, 0.24 and the second preset power threshold may be, for example, 0.05.
And when the charging data meets at least one item of the five items, judging that the battery of the electric vehicle has an aging phenomenon. On the contrary, when none of the above five items is satisfied, it is determined that the charging data does not satisfy the preset condition, at this time, it may be further determined whether the charging data satisfies other types, for example, whether the charging data is normal charging, whether the charging data is simultaneously charging for a plurality of vehicles, and the like, and of course, it may also be directly determined that the battery of the electric vehicle is not aged.
And S203, if the charging data meets the preset conditions, judging that the battery of the electric vehicle is aged.
According to the embodiment of the application, whether the battery of the electric vehicle is aged or not is judged by judging whether the electric vehicle charging data accord with the preset condition or not, the identification of the electric vehicle battery aging is realized, whether the electric vehicle battery is aged or not is known in time, the potential safety hazard of the electric vehicle charging process is reduced, and the safety of the electric vehicle charging process is improved.
The above step S202 will be further described below.
Referring to fig. 3, which is a schematic block diagram illustrating a specific process of step S202 provided in the embodiment of the present application, the specific process of determining whether the charging data meets the preset condition may include:
step S301, judging whether the charging time of the charging data is less than or equal to the charging time threshold. If the charging duration is less than or equal to the charging duration threshold, go to step S302. If the charging duration is greater than the charging duration threshold, the process proceeds to step S303.
And step S302, judging that the charging data meets the preset conditions.
Step S303, respectively judging whether the oscillation quantity of the charging data is greater than or equal to an oscillation quantity threshold value and whether the average voltage of the charging data is less than a preset threshold value; if the oscillation number is greater than or equal to the oscillation number threshold and the average voltage is less than the predetermined threshold, the process returns to step S302. Otherwise, if the oscillation number is smaller than the oscillation number threshold and/or the average voltage is greater than or equal to the preset threshold, the process proceeds to step S304.
Step S304, respectively determining whether the charging data has a second phase, whether the duration of the second phase is greater than or equal to a first preset duration threshold, whether the starting time point of the second phase is less than a preset time point, and whether the total charging amount of the charging process corresponding to the charging data is less than a preset charging amount threshold.
If the charging data has a second phase, the duration of the second phase is greater than or equal to the first preset duration threshold, the starting time point of the second phase is less than the preset time point, and the total charging amount of the charging process corresponding to the charging data is less than the preset charging amount threshold, the process returns to the step S302.
When at least one of the charging data does not have the second phase, the duration of the second phase is less than the first preset duration threshold, the starting time point of the second phase is equal to or greater than the preset time point, or the total charging amount of the charging process corresponding to the charging data is equal to or greater than the preset charging amount threshold exists, the flow proceeds to step S305.
Step S305, respectively determining whether the charging data has a second phase, whether the duration of the second phase is greater than the first preset duration threshold and less than or equal to the second preset duration threshold, and whether the current of the charging data is less than the preset current threshold.
If the charging data has a second phase, the duration of the second phase is greater than the first preset duration threshold and less than or equal to the second preset duration threshold, and the current of the charging data is less than the preset current threshold, the process returns to the step S302.
Otherwise, when at least one of the charging data does not have the second phase, the duration of the second phase is less than or equal to the first preset duration threshold or is greater than or equal to the second preset duration threshold, and the current of the charging data is greater than or equal to the preset current threshold, the step S306 is performed.
Step S306, respectively determining whether the total power of the charging data is smaller than a first preset power threshold and whether the average power is smaller than a second preset power threshold. If the total power of the charging data is smaller than the first preset power threshold and the average power is smaller than the second preset power threshold, the step S302 is returned to. Otherwise, if the total power of the charging data is greater than or equal to the first preset power threshold, and/or the average power is greater than or equal to the second preset power threshold, the step S307 is performed.
And step S307, judging that the charging data does not meet the preset condition.
It should be noted that the judgment process of the above 5 conditions may also be executed in parallel.
The manner of identifying whether the charging data meets the preset condition may be any, for example, the charging data is identified by a pre-trained neural network. However, compared with other identification methods, the method corresponding to fig. 3 performs intelligent calculation on the charging data directly according to the predefined condition, and the identification precision and the identification accuracy are higher.
The technical scheme for identifying the aging of the battery of the electric vehicle can be applied to various scenes. The charging pile scenario based on the system architecture shown in fig. 1 will be described below.
Referring to fig. 4, another schematic flow chart of a method for identifying battery degradation of an electric vehicle according to an embodiment of the present application may include the following steps:
step S401, charging order data of a user of the electric vehicle are obtained.
Specifically, after a user generates a charging order through a mobile phone or other terminal equipment, the user terminal equipment uploads the charging order to the server. The charging order data comprises but is not limited to information such as a user ID, an order electric quantity, a user mobile phone number, an order duration, an equipment ID of a charging pile, a socket serial number of the charging pile, an order ending reason code, an equipment type of the charging pile, an order starting time, an order ending time, a site ID of the charging pile, a site name of the charging pile, a box delivery number of the charging pile and the like.
And step S402, detecting whether the electric vehicle is analyzed according to the charging order data.
Specifically, after receiving the charging order data of the user, the server determines whether the electric vehicle of the user has been subjected to intelligent process charging curve analysis or not based on unique identification information such as a user ID of the charging order data, and if the electric vehicle of the user has been analyzed, generates prompt information according to a previous analysis result, and sends the prompt information to the user terminal device. And if the order is not analyzed, acquiring the charging data corresponding to the order for intelligent analysis.
Step S403, acquiring telemetering data corresponding to the charging pile through charging order data of a user of the electric vehicle, wherein the telemetering data comprises charging data.
Specifically, the server searches corresponding telemetering data from a database of the charging pile management platform according to a user ID, charging pile information, charging site information, order start/end time and the like in the charging order data, wherein the telemetering data is reported by the charging pile and generally comprises charging current data and charging voltage data.
And step S404, determining whether the charging data meets a preset condition.
And S405, if the charging data meet the preset conditions, judging that the battery of the electric vehicle is aged.
It should be noted that steps S404 to S405 are the same as steps S202 to S203, and for related introduction, reference is made to the above corresponding contents, which are not described herein again.
And step S406, generating prompt information and/or suggestion information of battery aging.
And step S407, sending the prompt information and/or the suggestion information to the terminal equipment of the user of the electric vehicle to instruct the terminal equipment to present the prompt information and/or the suggestion information to the user of the electric vehicle.
Specifically, the server may generate a prompt or advice message if it is determined that the battery of the electric vehicle is aged. The prompting information is used for prompting a user that the electric vehicle is aged, and the suggestion information is a countermeasure which can be adopted by the user aiming at the battery aging phenomenon. For example, the server generates information including prompt information and advice information, which is specifically "according to the intelligent analysis of the charging curve, you change little in the amount of electricity although charging for a long time, presumably due to aging of the battery, and advise you to repair or replace the battery".
It can be understood that, in the prior art, when a charging station is on fire or an electric vehicle spontaneously ignites in the charging process, a great part of safety accidents occur, namely, the battery health condition of the electric vehicle cannot be concerned or known in time by an electric vehicle owner, so that potential safety hazards in the charging process cannot be eliminated in time or in advance. And this application embodiment carries out intelligent analysis through the electric motor car charging data to filling electric pile report, judges whether user's electric motor car battery appears the battery phenomenon of ageing, if the battery ages, then generates tip information in order to warn the user for the user in time learns and concerns the battery health status of self electric motor car, in order to reduce or eliminate the potential safety hazard in the electric motor car charging process, improves the security of electric motor car charging process.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
