Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The charging device of the embodiment of the invention is in a constant power charging mode (namely the same charging time and the same charging energy), and the charging mode of the charging device is based on the step type charging price, namely the charging device charges the same electric quantity in different time periods and the user needs to pay different prices, wherein the charging price in the valley period is Pr1/kWh, the charging price in the normal period is Pr2/kWh, and the charging price in the peak period is Pr3/kWh, wherein Pr3 is more than Pr2 and more than Pr 1. In addition, the service provider can charge corresponding service fee for every power of the battery, but on the basis of Pr3 > Pr2 > Pr1, the price relationship of the valley period, the ordinary period and the peak period after charging the service fee is still the same.
As shown in fig. 1, which is a schematic diagram of distribution of different charging periods in a day, time division points between the different charging periods in fig. 1 are T1-T6, respectively. The embodiment of the present invention will be described with reference to fig. 1 as an example. Fig. 1 is only one distribution of different charging periods in a day, which is listed for convenience of subsequent description, and may actually be other distribution, fig. 1 should not constitute a limitation on different charging periods, and the charging analysis principle of other distribution of different charging periods is the same as that of the example in fig. 1.
The first embodiment is as follows:
referring to fig. 2, fig. 2 is a flowchart of a charging method according to an embodiment of the invention. The embodiment of the invention provides a charging method, which comprises the following steps:
step 201: and acquiring the amount of charge to be charged of the battery.
The charge amount is the electric quantity required to be charged into the battery by the charging device. The mode of acquiring the amount to be charged can be receiving the amount to be charged input by the user; it may also be a percentage to be charged that receives user input, and the amount to be charged is determined by the percentage to be charged and the battery capacity, for example: the user inputs the percentage to be charged to be 20%, and the charging device obtains the amount to be charged according to the product of the percentage to be charged and the capacity of the battery to be charged. The above list is merely a few specific possible solutions, and is not considered as a limitation to obtain the amount of charge to be charged of the battery.
Step 202: generating a reference charging strategy based on the amount to be charged; wherein the reference charging strategy comprises at least one of a first charging strategy and a second charging strategy; the first charging strategy comprises a shortest occupying time length required for completing charging and a first charging fee corresponding to the shortest occupying time length; the second charging strategy includes a minimum charging rate required to complete charging and a first occupancy period corresponding to the minimum charging rate.
After the amount to be charged is determined, the charging amount per hour is determined, that is, the actual charging time can be determined, and then the first charging strategy and/or the second charging strategy can be generated based on the distribution situation of different charging periods in one day.
The charging device comprises a charging device, a charging system and a charging control device, wherein the occupying time is the time for occupying the charging device during charging, namely the time from the occupying starting time point to the occupying ending time point of the charging device occupied by a battery, and the shortest occupying time is the charging time required for occupying the charging device and leaving the charging device all the time until charging is completed; the lowest charging cost is the time period when the battery is charged is the lowest price (i.e. the valley time period), and the charging electric quantity reaches the cost required by the user to be charged.
In an embodiment of the present invention, the occupancy starting time point may be a time point when the charging device detects a battery to be charged, for example: when a vehicle is plugged in a charging gun of a charging pile, the charging pile acquires a current time point as an occupied initial time point; alternatively, the occupation start time point may be set by the user; alternatively, the charging device may use the target charging policy received from the user as the occupation starting time point, or may determine the occupation starting time point in other manners, which are only examples and should not be regarded as limitations to the manner of determining the occupation starting time point.
It should be noted that the occupation end time point is the earliest time point at which the battery can no longer occupy the charging device after being fully charged. The point in time when the battery leaves the charging device after it has been connected to the charging device for a period of time during which the charging device is not charging the battery after completion of charging does not belong to the occupation end point in the embodiment of the present invention.
The generated reference charging strategy can be viewed by a user, wherein the shortest occupation time, the first occupation time, the lowest charging fee and the first charging fee can be displayed through a display screen or a light-emitting diode panel.
Step 203: receiving a target charging strategy set by a user according to the reference charging strategy, and charging the battery according to the target charging strategy; wherein the target charging strategy comprises a target occupancy duration and a target charging fee.
When a user sets a target charging strategy, the user can check the reference charging strategy, the first charging strategy can be directly adopted as the target charging strategy, the second charging strategy can be directly adopted as the target charging strategy, the set occupation time or charging cost can be adjusted according to the reference charging strategy and the actual charging requirement of the user, the target charging strategies different from the first charging strategy and the second charging strategy are obtained, and the subsequent charging device charges the battery according to the target charging strategies. For example:
when the reference charging strategy comprises a first charging strategy, a user can determine a target charging strategy by setting an occupation time length, wherein the occupation time length which can be set by the user is greater than or equal to the shortest occupation time length, and the charging cost corresponding to the target charging strategy is less than or equal to the first charging cost;
when the reference charging strategy comprises a second charging strategy, the user can determine the target charging strategy by setting the charging fee, at this time, the charging fee which can be set by the user is greater than or equal to the lowest charging fee, and the occupied time length corresponding to the target charging strategy is less than or equal to the first occupied time length.
As shown in fig. 1, taking an example that the amount to be charged needs to be charged for 3 hours, the initial time point of occupation is 13 points, and the reference charging policy is the first charging policy, if the user is time-strained and needs to be charged up at the fastest time, the user may use the first charging policy as the target charging policy, so that the charging device starts charging from 13 points until the charging of the battery is completed at 16 points, and the user needs to pay Pr3+2Pr 2; if the user time is relatively abundant and can stay for 4 hours, the occupied time of the target charging strategy is 4 hours, the charging device occupies the charging device from 13 points and starts charging from 14 points until 17 points finish charging the battery, and at the moment, the user only needs to pay 3Pr2, which is less than Pr3+2Pr2 paid at the fastest speed, so that the payment cost of the user is reduced.
In the embodiment of the invention, the charging device can provide the reference charging strategy for the user, so that the user can conveniently set the charging time and the charging expense in the target charging strategy according to the requirement of the user, the charging expense required to be paid by the user can be reduced by charging the battery through the strategy with lower charging expense under the condition of sufficient time, and the charging cost of the user is saved.
The second embodiment:
as shown in fig. 3, fig. 3 is a flowchart of a charging method according to another embodiment of the present invention. An embodiment of the present invention provides a charging method, including:
step 301: receiving the end electric quantity of the battery set by a user when charging is completed, and acquiring the initial electric quantity of the battery;
step 302: and taking the electric quantity difference value between the ending electric quantity and the starting electric quantity as the to-be-charged quantity of the battery.
The charging device can acquire the initial electric quantity of the battery before charging after being connected with the battery, and then receives the end electric quantity of the battery after charging is finished when the user sets the end of the occupation through the input of the operation interface, so as to calculate the to-be-charged quantity.
The start electric quantity and the end electric quantity may both be electric quantity percentages of the battery, and then the amount to be charged is determined based on the capacity of the battery, for example: the initial charge amount is 31%, and the end charge amount is 100%, then the amount to be charged is obtained based on 69% and the capacity of the battery.
Step 303: generating a reference charging strategy based on the amount to be charged.
The implementation process and beneficial effects of step 303 may refer to the description in step 202, and are not described herein again.
In an alternative embodiment, if the reference charging strategy includes a first charging strategy (i.e. a shortest occupied time period required for completing charging and a first charging fee corresponding to the shortest occupied time period), then the step 303 of generating the reference charging strategy based on the amount to be charged may include the step of generating the first charging strategy, and the step of generating the first charging strategy may include:
determining a charging time length based on the charge amount to be charged and the charge amount in unit time;
and taking the charging time as the shortest occupying time, and calculating the first charging fee based on the shortest occupying time.
Namely, a reference charging strategy is generated, wherein the charging time length is used as the shortest occupation time length, and the charging cost between the occupation starting time point and the occupation ending time point is used as the first charging cost, and the time length between the occupation ending time point and the occupation starting time point is equal to the charging time length.
The charging time is the charging time of the display device to the battery within the occupied time, and the charging time is less than or equal to the occupied time. And under the condition that the occupied time length is equal to the charging time length, the occupied time length is shortest. The first charging fee is the sum of the charging fees at the occupation start time point and the occupation end time point.
As shown in fig. 4, taking the charging time as 5 hours as an example, when the initial occupancy time point a is 13 points, the end occupancy time point a' is 18 points, and the first charging fee can be calculated as 2Pr3+3Pr 2; when the occupancy start time point B is 2 points, the occupancy end time point B' is 7 points, and the first charging fee can be calculated to be 4Pr1+ Pr 2. As a result, the first charging cost is related to the occupancy duration and the occupancy start time.
In the embodiment, when the reference charging strategy comprises the first charging strategy, the shortest occupying time and the corresponding first charging cost can be quickly and accurately calculated, and a user can conveniently make a target charging strategy according to the shortest occupying time and the corresponding first charging cost under the condition of time shortage.
It should be noted that, based on the amount to be charged and the amount of charge in the unit time, the charging period is determined;
and taking the charging time as the shortest occupying time, and calculating the first charging fee based on the shortest occupying time. The same applies to the embodiment shown in fig. 2, with the same advantageous effects.
In an alternative embodiment, if the reference charging policy includes a second charging policy (i.e. the shortest charging fee required for completing charging and the first occupied time period corresponding to the shortest charging fee), then the step 303 of generating the reference charging policy based on the amount to be charged may include the step of generating the second charging policy, and the step of generating the second charging policy may include:
determining a charging time length based on the charge amount to be charged and the charge amount in unit time;
and taking the charge required by the charging time length distributed in the valley time period as the lowest charging charge, and determining the first occupation time length according to the occupation starting time point and the latest time point of the charging time length distributed in the valley time period after the occupation starting time point.
The charging duration is distributed at the latest time point in the valley time period, namely the time point for finishing charging, and the charging device does not need to be occupied after charging is finished, so that the charging device also occupies the finishing time point. The time length between the occupation starting time point and the occupation ending time point is the occupation time length. The valley period corresponding to the lowest charging fee may be a complete period of time or a dispersed plurality of periods of time, the earliest time point of the valley period may be an occupation starting time point, or may be a period of time after the occupation starting time point, and no matter which form of the valley period, the valley period included between the occupation ending time point and the occupation starting time point is equal to the charging period.
The charging method comprises the steps of generating a lowest charging cost which is the cost required by charging all the charging time periods in a valley time period, and taking the time period between an occupation starting time point and the latest time point of the charging time period distributed in the valley time period after the occupation starting time point as a reference charging strategy of a first occupation time period, wherein the valley time period equal to the charging time period is included between the occupation ending time point and the occupation starting time point.
As shown in fig. 5, for example, the charging duration is 5 hours, the lowest charging fee is 5Pr1, but different occupancy start time points may occupy different end time points. When the occupation starting time point C is 16 points, the charging can be carried out only when 23 points are needed, the charging is finished at 4 points on the next day after 5 hours, and the 4 points on the next day are the occupation finishing time point C'; when the occupation starting time point D is 24 points, the charging can be started immediately, the occupation time length is equal to the charging time length and is 5 hours, and the next day of 5 points is the occupation ending time point D'.
In this embodiment, when the reference charging policy includes the second charging policy, the minimum charging cost and the corresponding first occupation duration can be quickly and accurately calculated, so that the user can conveniently set the target charging policy according to the minimum charging cost and the corresponding first occupation duration under the condition of sufficient time.
It should be noted that, based on the amount to be charged and the amount of charge in the unit time, the charging period is determined; and taking the charge required by the charging time length distributed in the valley time period as the lowest charging charge, and calculating the first occupation time length based on the occupation starting time point and the occupation ending time point corresponding to the lowest charging charge. The same applies to the embodiment shown in fig. 2, with the same advantageous effects.
Step 304: and receiving a target charging strategy set by a user according to the reference charging strategy, and charging according to the target charging strategy.
The target occupation time is greater than or equal to the shortest occupation time, and the target charging cost is less than or equal to the first charging cost; and/or the presence of a gas in the gas,
the target occupying time length is less than or equal to the first occupying time length, and the target charging cost is greater than or equal to the lowest charging cost.
The implementation process and beneficial effects of step 304 may refer to the description in step 203, and are not described herein again.
The user can check the reference charging strategy on the operation interface, namely check the shortest charging time and the first charging cost when the reference charging strategy only comprises the first charging strategy; looking at the lowest charge rate and the first charge duration when the reference charge strategy includes only the second charge strategy; when the reference charging strategy includes both the first charging strategy and the second charging strategy, the shortest charging period, the first charging rate, the lowest charging rate, and the first charging period are observed, as shown in fig. 6.
In an optional embodiment, the user may adjust the occupied time period, so that the charging fee is automatically adjusted according to the occupied time period and the distribution of different charging periods. At this time, the target charging strategy set by the user is obtained by the following steps:
receiving the target occupation duration input by a user;
and generating the target charging cost based on the target occupation time.
Under the condition that a user inputs a target occupation time length according to a display panel, the process of generating the target charging fee comprises calculating and displaying the target charging fee corresponding to the target occupation time length.
Specifically, when the reference charging policy includes a first charging policy, the method may include:
receiving a target occupation time length input by a user, wherein the target occupation time length is greater than or equal to the shortest occupation time length; calculating a lowest charging fee between an occupation start time point and an occupation end time point as a target charging fee, wherein a time length between the occupation end time point and the charging start time point is equal to the target occupation time length, and the target charging fee is less than or equal to the first charging fee.
Specifically, when the reference charging strategy includes the second charging strategy, the method may include:
receiving a target occupation duration input by a user, wherein the target occupation duration is less than or equal to the first occupation duration; calculating a minimum charging fee between an occupancy start time point and an occupancy end time point as a target charging fee, wherein a time period between the occupancy end time point and the charging start time point is equal to the target occupancy time period, and the target charging fee is greater than or equal to the minimum charging fee.
When the reference charging strategy comprises a first charging strategy, the target occupation time length set by the user is not less than the shortest occupation time length, and the target charging cost obtained after adjustment is not higher than the first charging cost; when the reference charging strategy comprises a second charging strategy, the target charging time set by the user is not longer than the first charging time, and the adjusted target charging cost is not less than the lowest charging cost.
The lowest charging rate between the occupation start time and the occupation end time is taken as the charging rate, and can be understood as follows: when a valley period between the occupation starting time point and the occupation ending time point is greater than or equal to the charging time, charging the battery only in the valley period; when the valley period between the occupation starting time point and the occupation ending time point is less than the charging period, the period exceeding the valley period is used for preferentially charging the battery in the flat period.
Taking the initial occupation time S of 5 points, the charging time of 6 hours, and the occupation time set by the user of 10 hours as an example: the shortest occupation time corresponding to the first charging strategy is 6 hours, and the first charging cost is Pr1+3Pr2+2Pr 3; the second charging strategy corresponds to a minimum charging cost of 6Pr1 and a first occupancy duration of 23 hours. After the user specifies the charging time period, the occupation ending time point S' is determined to be 15 points, and charging is performed by using 6 hours with the relatively lowest cost between 5 points and 15 points, as shown in fig. 7, so that the charging cost is Pr1+4Rr2+ Pr 3.
In the embodiment, the user can flexibly adjust the occupied time in the target charging strategy according to the reference charging strategy and the time for waiting for charging, the battery is charged in the mode of lowest payment cost within the time for waiting for charging, and the payment cost of the user is reduced on the basis of ensuring the requirement of the user on the occupied time.
In another alternative embodiment, the user may adjust the charging fee so that the occupied time period is automatically adjusted according to the charging fee and the distribution of different charging periods. At this time, the target charging strategy set by the user is obtained by the following steps:
receiving the target charging fee input by a user;
and generating the target occupation time length based on the target charging cost.
Under the condition that a user inputs target occupation time according to a display panel, the target occupation time is generated by calculating and displaying the target occupation time corresponding to the target charging cost.
Specifically, when the reference charging policy includes a first charging policy, the method may include:
receiving a target charging fee input by a user, wherein the target charging fee is greater than or equal to the minimum charging fee; calculating the shortest time length between the occupation starting time point and the occupation ending time point as a target occupation time length, wherein the actual charging cost between the occupation ending time point and the occupation starting time point is equal to the target charging cost, and the target occupation time length is less than or equal to the first occupation time length.
Specifically, when the reference charging strategy includes the second charging strategy, the method may include:
receiving a target charging fee set by a user, wherein the target charging fee is less than or equal to the first charging fee; calculating the shortest time length between the occupation starting time point and the occupation ending time point as a target occupation time length, wherein the actual charging cost between the occupation ending time point and the occupation starting time point is equal to the target charging cost, and the target occupation time length is greater than or equal to the shortest occupation time length.
When the reference charging strategy comprises a first charging strategy, the charging cost set by the user is not higher than the first charging cost, and the occupied time length obtained after adjustment is not lower than the shortest occupied time length; when the reference charging strategy comprises a second charging strategy, the charging cost set by the user is not lower than the lowest charging cost, and the occupied time length obtained after adjustment is not higher than the first occupied time length.
If the user adjusts the first charging rate Prmax to the target rate Prre with reference to the first charging strategy (as shown in fig. 8a, Q is the occupation start time point, and Q' is the occupation end time point): when Prmax-Prre ≦ (T4-T3). times.Pr 2, it is necessary to shift the partial charging time of the T2-T3 period to the T3-T4 period, assuming that the period of time remaining in the T2-T3 charging is X1 and the period of time shifted to the T3-T4 period is X2, then the following equation applies:
from equation 4, it can be derived:
thereby obtaining that the adjusted occupation time is: T-T3-T0 + X2 as shown in fig. 8 b.
