Detailed Description
The application discloses a recommendation method for charging reservation. The method is based on a background, a mobile terminal and a charging station. The backstage can be the server, and mobile terminal and charging station all can with the server between signal transmission, but the charging station is equipped with a plurality of electric pile that fill in, but the state of charging station real-time detection electric pile. When the user needs to charge the automobile, a request is sent to the server through the mobile terminal, the server pushes a charging plan to the user according to information transmitted by the charging pile, and after the user inserts the charging gun into the automobile, the server can communicate with the charging station and control the charging pile to be used according to the charging plan, so that charging can be smoothly completed.
In one embodiment, as shown in fig. 1, there is provided a recommendation method for a reserved charging, the method comprising the steps of:
s10, receives the charge reservation request transmitted from the mobile terminal.
Specifically, a user sends a charging reservation request to a background through a mobile terminal, wherein the charging reservation request comprises the residual electric quantity before charging, identity identification information, charging starting time and a positioning position where the mobile terminal is located. The mobile terminal can be a smart phone or a smart device carried on a vehicle, and the identity identification information is the only identity information of the user. The location position may be a GPS location. The remaining capacity is the remaining capacity of the vehicle before charging, which is input by the user.
And S11, calculating the charging time length corresponding to the charging reservation request.
Specifically, the background subtracts the residual capacity from the preset standard full capacity to obtain the amount to be charged, and obtains the charging duration corresponding to the charging reservation request according to the amount to be charged and the preset standard charging power. The standard full charge is preset by a user according to a driven vehicle and is the charge when the vehicle is fully charged. The standard charging power is preset by background staff by analyzing the charging power of a large number of charging stations.
And S12, selecting optional charging stations from all the charging stations.
Specifically, the background selects, from among all the charging stations, a charging station whose distance from the corresponding location information to the positioning location of the mobile terminal is within a preset reasonable distance, which may be a linear distance between two location points on the map. A reasonable distance may be 5 km. And selecting the charging station of the specific charging pile in the idle state as an optional charging station from the selected charging stations. Every charging station is provided with unique positional information, when filling electric pile and being occupied, fills electric pile and be the in service state, when filling electric pile not occupied, is idle state.
And S13, calculating a first charging amount corresponding to each selectable charging station.
Specifically, the background calls out a preset electricity price value of each time period of the selectable power station in a preset time length range from a preset electricity price database. The unit of electricity price value may be yuan/kwh. The preset time length may be twelve hours, and the time length of each time period may be one hour or two hours. The electricity price value is preset by the staff according to the electricity price of each power station. The charging time length is multiplied by the standard charging power to obtain the charging amount of each time period, and the electricity price value is multiplied by the electric amount to obtain the charging fee of each time period. And adding the charging starting time to the charging duration to obtain charging ending time, and adding the charging cost of each time period between the charging starting time and the charging ending time to obtain a first charging amount corresponding to each optional charging station. For example, the start charging time is 14: 00, the charging time is 2 hours, the charging end time is 16: 00 with an hourly charge of 150 kilowatt-hours. The electricity rate value of the time period of the optional charging station a is 14: 00-15: 00 is 1 yuan/kwh, 15: 00-16: when 00 is 1.2 yuan/kwh, the charging time of the two time periods is 1 hour respectively. Then a first charge amount is 150 kw x 1 hour x 1 element/kw hour +150 kw x 1 hour x 1.2 elements/kw hour =330 elements.
And S14, selecting the target charging station corresponding to the first charging plan.
Specifically, after calculating a first charging amount corresponding to each optional charging station, the background selects an optional charging station with the lowest first charging amount from all the optional charging stations, takes the selected optional charging station as a target charging station, and generates a first charging plan, where the first charging plan includes the calculated charging duration, the first charging amount, and location information of the target charging station.
And S15, sending the first charging plan to the mobile terminal.
Specifically, the background sends the generated first charging plan to the mobile terminal, and after receiving the first charging plan, the user can go to the target charging station directly according to the provided position information of the target charging station to perform charging.
In another embodiment, considering that the provided charging plan is relatively single and is not enough to cover the problem of user requirement, as shown in fig. 2, a recommendation method for reserved charging may further include the following steps:
and S20, selecting the charging time period corresponding to each optional charging station.
Specifically, S20 may follow S12. After the selectable charging stations are selected, the background compares the charging starting time with the time period preset by each selectable charging station in sequence, judges whether the charging starting time falls within a certain time period of the selectable charging stations, and if so, adjusts the charging starting time to the starting time of the time period; otherwise, no adjustment is made. For example, one time period for optional charging station B is 13: 30-14: 30, start charging time 14: 00, the time period is adjusted to 14: 00-14: 30. and sequentially selecting the time periods with the minimum electricity price value as charging time periods in the corresponding time periods of each selectable charging station within a preset time length range from the charging starting time until the sum of the time lengths of the selected charging time periods is not less than the charging time length. And the last selected charging time period is the last time period. The preset time length can be 12 hours or 6 hours or smaller according to the use condition of the user. The time period with the smallest electricity price value is selected from the time periods from the starting charging time to the next twelve hours of the optional power station, and each time period corresponds to one electricity price value. For example, the charging time is 14: 00, the charging time is 2 hours, the preset time length is 6 hours, and the price of each time period of the optional charging station B is 13: 30-14: 30, 1.1 yuan/kilowatt-hour; 14: 30-15: 30, 0.9 yuan/kwh; 15: 30-16: 30, 1.3 yuan/kwh; 16: 30-17: 30, 1.2 yuan/kwh; 17: 30-18: 30, 1.3 yuan/kwh, 18: 30-19: 30, 1.3 yuan/kwh, wherein 13: 30-14: the 30 time period is adjusted to 14: 00-14: 30, the time period selected in turn is 14: 30-15: 30, 14: 00-14: 30 and 16: 30-17: and 30, taking 2.5 hours totally, and stopping selection if the time is more than 2 hours. Wherein 16: 30-17: and 30 is the last bit period. If the time periods with the same electricity price value exist, the time period closer to the charging starting time is preferably selected during selection.
And S21, calculating the time period electricity price corresponding to each charging time period.
Specifically, the time period electricity price corresponding to each charging time period is calculated according to the charging time length corresponding to each charging time, the standard charging power and the electricity price value, and the charging time length corresponding to the last time period is the time length left after the charging time length minus the time lengths of all the time periods selected before the last time period, for example, as in the above example, 16: 30-17: 30 is the last time period, then 16: 30-17: the charging time of 30 is 2 hours minus 0.5 hours minus 1 hour to 0.5 hours. The charging time length corresponding to the rest time periods is the time length of the time periods. And multiplying the charging time length by the standard charging power and then multiplying by the electricity price value to obtain the time period electricity price of each charging time period.
And S22, calculating a second charging amount corresponding to each optional charging station.
Specifically, the calculated electricity prices of all the time periods corresponding to each optional charging station are added, so that a second charging amount corresponding to each optional charging station can be obtained, namely the lowest charge of each optional charging station for full charging in a preset time range. The preset time range may be set to 12 hours or 6 hours.
And S23, selecting a target charging station corresponding to the second charging plan.
Specifically, the selectable charging station with the smallest corresponding second charging amount is selected as the target charging station of the second charging plan, and the second charging plan includes the second charging amount and the location information corresponding to the target charging station.
And S24, sending the first charging plan and the second charging plan to the mobile terminal.
Specifically, the background sends the second charging plan to the mobile terminal, if the user selects the second charging plan, the user inserts the charging gun into a charging port of the vehicle after driving the vehicle to a corresponding target charging station, and sends the identity identification information to the background through the charging pile, and the background can send an instruction to the charging station, so that the charging pile used by the user is charged within a charging time length corresponding to each charging time period, and the charging is suspended in the rest time until the electric quantity is charged to the standard full electric quantity.
In another embodiment, considering the situation that when the charging time is longer, the user will process other transactions during the charging period, but needs to estimate the charging end time by himself, after selecting the target charging station corresponding to the first charging plan, the background adds the charging start time to the charging time period to obtain the charging end time of the first charging plan, and adds the obtained charging end time to the first charging plan. Meanwhile, after the target charging station corresponding to the second charging plan is selected, the background judges whether the last time period is the latest of all the selected charging time periods, if so, the starting time of the last time period is added with the charging time corresponding to the last time period to obtain the charging ending time of the second charging plan; otherwise, the end time of the latest charging period is taken as the charging end time of the second charging plan. The background adds the derived charge end time to the second charging schedule. When the first charging plan and the second charging plan are sent to the user in the background, the user can directly know the respective charging end time of the two charging plans, and other affairs in the charging period are reasonably arranged according to the charging end time.
Considering a case where the charging post in the idle state in the target charging station may be repeatedly selected and occupied by other users during the user' S travel to the target charging station after the user selects the target charging station, at S24: the method comprises the steps of sending a first charging plan and a second charging plan to a mobile terminal, then receiving selection information aiming at the first charging plan and the second charging plan sent by the mobile terminal by a background, and changing the state of one idle state charging pile of a target charging station in the selection information into an in-use state by the background, so that the background occupies the position of the one idle state charging pile in the target charging station in advance. When the user selects the first charging plan, the target charging station is the target charging station of the first charging plan; when the user selects the second charging plan, the target charging station is the target charging station of the second charging plan. Charging is completed, after the user gets the car, charging end information can be sent to the background through the mobile terminal, and the background changes the state of one charging pile in the target charging station into an idle state in use, so that the charging pile is released.
In another embodiment, considering that in a charging peak period, the number of the idle-state charging piles is small, and there is a situation that other users cannot find the idle-state charging pile because the users forget to take the car in time after charging is completed, after the background changes the state of one of the target charging stations in the idle-state charging pile into the in-use state, when the charging end time is reached, the background changes the state of one of the target charging stations in the in-use state into the selectable state. And after the background receives the charging reservation request, if the distance from the corresponding position information to the positioning position of the mobile terminal is within a preset reasonable distance, and no charging station with a charging pile in a specific idle state exists, judging that a charging station with a selectable state exists, and if so, sending a vehicle taking reminder to the mobile terminal reaching the charging end time in the charging station. The content of the vehicle taking reminder can comprise the reminding content and the position information of the charging station where the vehicle is located. In order to remind the user in time to get the car, release and fill electric pile.
In one embodiment, considering the situation that when an obstacle exists between the positioning position and the position of the charging station, the actual driving distance is far more than the straight-line distance on the map, and when the electric quantity of the vehicle is insufficient, the vehicle cannot reach the target charging station, after receiving a charging reservation request sent by a user, the background draws a circle with a preset radius in a preset map by taking the positioning position in the charging reservation request as the center, and selects the charging station in the circle, wherein the preset radius can be 5 kilometers. The preset map can be a map provided by existing map software. And the background respectively calculates the driving distance from the selected charging station to the positioning position in the map, and divides the residual electric quantity by the preset power consumption per kilometer to obtain the drivable distance corresponding to the charging reservation request. The power consumption per kilometer is preset by the user according to the automobile condition. The background judges whether the drivable distance is smaller than a preset reasonable distance or not, if so, the drivable distance is screened out from the selected charging stations, and the charging stations with idle charging piles are taken as optional charging stations; otherwise, screening out the charging stations with driving distances smaller than a reasonable distance, and taking the charging stations with the charging piles in the idle state as optional charging stations. Therefore, the distance actually reaching the target charging station calculated by the background is more accurate, and the possibility that the vehicle cannot reach the target charging station when the electric quantity of the vehicle is insufficient is reduced.
Considering a case where the charging habit of the user is not necessarily a full charge, a recommendation method for a scheduled charging may further include the steps of:
and S30, receiving the charging end information sent by the target mobile terminal.
Specifically, when the user confirms that the vehicle is taken away after the charging is finished, charging end information is sent to the background through the mobile terminal, and the charging end information comprises the residual electric quantity after the charging and the identification information. The target mobile terminal may be any one of the mobile terminals.
And S31, recording the abnormal event.
Specifically, when the charged remaining capacity is smaller than the standard full capacity corresponding to the identification information, recording that the charged remaining capacity is smaller than the standard full capacity as an abnormal event.
And S32, determining the pre-charging amount corresponding to the target mobile terminal.
Specifically, the background judges whether the number of days from the recording time of the first abnormal event to the recording time of the last abnormal event is less than a preset number of days threshold, if so, calculates the average value of all charged residual electric quantities from the first abnormal event to the last abnormal event, and takes the calculated average value as the pre-charging quantity corresponding to the identification information; otherwise, calculating the average value of all charged residual electric quantities within the preset day threshold value, and taking the calculated average value as the pre-charging quantity corresponding to the identity identification information. And when the background calculates the amount to be charged after receiving the charging reservation request, acquiring the pre-charging amount corresponding to the identity information, and subtracting the residual electric quantity from the acquired pre-charging amount to obtain the amount to be charged.
According to the recommendation method for the reserved charging, when a user needs to charge the automobile, the background can automatically recommend two charging plans to the user according to the position of the user and the electricity prices of different power stations, one charging plan adopts a charging mode of continuously charging from the charging starting time, and a charging station with the lowest charging cost in the charging mode can be selected; the other charging plan adopts a charging mode that charging is started from the charging starting time only at low electricity price and charging is suspended at high electricity price, and a charging station with the lowest charging cost in the charging mode can be selected, so that a user can conveniently select a proper charging plan according to the self requirement during charging. And the background can adjust and calculate the numerical value of the parameter in the charging plan according to the charging habit of the user, so that the generated charging plan is more in line with the charging habit of the user.
