Technical Field

Background

In order to ensure that the shared electric bicycle can meet the riding requirements of users, operators of the shared electric bicycle can periodically check and replace batteries of the shared electric bicycle. Generally, in order to ensure the maximization of the electric power benefit, and avoid the situation that the electric power of the shared electric bicycle is completely emptied to cause that the shared electric bicycle cannot be positioned, an operator can preset an electric replacement threshold for replacing a battery, and mark the shared electric bicycle as the electric bicycle needing to be replaced when the electric power of the shared electric bicycle falls below the electric replacement threshold, so as to dispatch a service staff to replace the battery of the electric bicycle.

In the prior art, the power-change threshold is typically set empirically. Typically 1/3. However, since the shared electric bicycle operates in a plurality of areas at the same time, the situation of each area is different, and if a unified power conversion threshold is set for each area, the electric quantity of the electric bicycle in a part of the areas is inevitably wasted, and the electric quantity of the electric bicycle in the other area is often insufficient.

Detailed Description

The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

In one embodiment, as shown in fig. 1, a method for determining a power change threshold of an electric bicycle is provided, and this embodiment is illustrated by applying the method to a server, where it is understood that the method may also be applied to a terminal, and may also be applied to a system including the terminal and the server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the steps of:

Step 102, acquiring each historical order of each first sample electric bicycle located in the target area in the historical time period.

In the embodiment of the present application, the historical time period is a period of time before the current time, for example, 7 days before the current day, one month before the current month, etc., and the specific length thereof may be set by those skilled in the art according to actual requirements. The target area is a preset area where the power change threshold needs to be calculated, such as an operation area in a city, a city and the like. The first sample electric bicycle can be selected from electric bicycles which are in the target area in the history time period, and a person skilled in the art can set and select the standard of the first sample electric bicycle according to actual requirements: for example, an electric bicycle with a parking time greater than a time length threshold in the target area is used as a first sample electric bicycle, an electric bicycle with an order in the target area is used as a first sample electric bicycle, and the embodiment of the present application is not limited thereto specifically. The historical orders for the first sample electric bicycle are orders that the first sample electric bicycle generated during a historical period of time.

Step 104, for any first sample electric bicycle, determining the power consumption weight of the first sample electric bicycle based on each historical order of the first sample electric bicycle.

In the embodiment of the application, as the conditions of different first sample electric bicycles are different, the data reliability is also different, and therefore, each first sample electric bicycle can be respectively provided with a power consumption weight for representing the reliability of the historical standby power consumption provided by the first sample electric bicycle.

The power consumption weight may be determined from a historical order of the first sample electric bicycle: for example, because the temperature of the parking environment has an influence on standby power consumption, the place and time of each historical standby power consumption generated by the first sample electric bicycle can be obtained according to the historical order of the first sample electric bicycle, and then the power consumption weight corresponding to the first sample electric bicycle is set according to the temperature of each place at each time: for example, the power consumption weight corresponding to the first sample electric bicycle with more historical standby power consumption generated at the moment of more extreme air temperature can be lower, and the power consumption weight corresponding to the first sample electric bicycle with more normal air temperature can be higher. Or because the battery health state also has an influence on the power consumption of the machine, and the frequency of using the electric bicycle is related to the battery health state, the battery health state of the first sample electric bicycle can be presumed according to the number of the historical orders of the first sample electric bicycle (for example, the battery health state corresponding to the first sample electric bicycle with larger number of the historical orders is lower, the battery health state corresponding to the first sample electric bicycle with smaller number of the historical orders is higher), and then the power consumption weight of each first sample electric bicycle is set according to the battery health state: for example, the first sample electric bicycle with poor battery health state has lower power consumption weight, and the first sample electric bicycle with good battery health state has higher power consumption weight. The power consumption weight of each first sample electric bicycle may also be set according to other criteria, which is not particularly limited in the embodiment of the present application.

And step 106, determining the daily standby power consumption of each first sample electric bicycle according to the historical standby power consumption of each first sample electric bicycle.

In the embodiment of the application, because the power change is generally carried out once a day, the daily standby power consumption of the electric bicycle needs to be considered when the power change threshold is calculated. The daily standby power consumption refers to power consumption required for the electric bicycle to perform standby for 24 hours. By way of example, the daily standby power consumption of the first sample electric bicycle may be calculated by summing up the historical standby power consumption of the first sample electric bicycle and the standby time periods corresponding to the historical standby power consumption, respectively, and further according to the ratio of the sum of the historical standby power consumption to the sum of the standby time periods.

Step 108, determining a standby electric quantity threshold according to the power consumption weight of each first sample electric bicycle and the daily standby power consumption of each first sample electric bicycle.

In the embodiment of the application, the standby electric quantity threshold value is used for representing the average electric quantity required by the electric bicycle in the target area for standby in one day. The amount of power should be greater than or equal to the average daily standby power consumption of the electric motor cars in the target area. The daily standby power consumption of each first sample electric bicycle can be weighted and summed according to the power consumption weight of each first sample electric bicycle, and then the sum result is divided by the number of the first sample electric bicycles, so that the average daily standby power consumption is obtained. The average daily standby power consumption can be directly used as a standby power quantity threshold value; or considering that in some target areas with larger areas or more scattered electric bicycle distribution, the batteries of the electric bicycle may not be replaced once a day, and a corresponding area coefficient may be set for each target area, so that the area coefficient is positively related to the area of the target area or the scattering degree of the electric bicycle, and further the product of the average daily standby power consumption and the area coefficient is used as the standby power threshold.

Step 110, determining a power conversion threshold for the target area according to the standby power threshold and the driving parameters of each second sample electric bicycle in the target area.

In the embodiment of the application, the second sample electric bicycle and the first sample electric bicycle can be the same electric bicycle or different electric bicycles. Because the update frequency of the standby electric quantity threshold value can be slower, and the electric quantity change threshold value is preferably updated in real time according to the running condition of each electric bicycle in the target area, the second sample electric bicycle can be the electric bicycle in the target area in a time period which is closer to the current time than the historical time period. For example, if the first sample electric bicycle is an electric bicycle that is in the target passing area in the 7 days before the present day, the second sample electric bicycle may be an electric bicycle that is in the target passing area in the 1 days before the present day.

The travel parameter refers to a parameter related to each travel of the electric bicycle, such as the number of travels, a travel duration, a travel mileage, a travel power consumption, and the like. Because the operation and maintenance personnel start to arrive at the position of the electric bicycle and change the electric bicycle for a certain period of time, the operation and maintenance personnel are informed of the need of changing the electric bicycle when the electric quantity of the electric bicycle is reduced to the standby electric quantity threshold value, and the electric bicycle cannot be used before the operation and maintenance personnel change the electric bicycle, so that the service efficiency of the vehicle is reduced; therefore, a power change threshold value which is not lower than the standby power threshold value can be determined according to the driving parameters and the standby power threshold value, so that the power change threshold value can consider the power required by the power change still in the operation state and still receiving orders in a time period for notifying the operation and maintenance personnel that the power of the power bicycle needs to be changed to the power change before the operation and maintenance personnel.

For example, the vehicle effect (that is, the ratio of the daily order amount (running times) to the number of all available electric bicycles in the area) of the target area may be calculated according to the running times of the second sample electric bicycles, and the average power consumption of each order of the target area may be calculated according to the running power consumption of the second sample electric bicycles, and further the power change threshold may be calculated according to the vehicle effect, the average power consumption and the standby power threshold. For example, the vehicle effect may be multiplied by the average power consumption, and then the multiplied result may be added to the standby power threshold, so as to obtain the power conversion threshold. Or considering that the electric quantity of the electric bicycle cannot be reduced to the standby electric quantity threshold value in the process of carrying out an order by a user, judging the longest mileage in a normal range according to the driving mileage of each second sample electric bicycle (for example, an outlier detection algorithm can be adopted to remove outliers, the longest mileage in the rest driving mileage is taken, or the longest mileage is obtained by adopting a statistical method, the embodiment of the application is not particularly limited to the above), and then adding the power consumption corresponding to the longest mileage to the standby electric quantity threshold value to obtain the power conversion threshold value. In addition, a coefficient may be given to each vehicle effect, and a product of the coefficient corresponding to the vehicle effect of the target area and the standby power threshold may be used as the power conversion threshold.

After determining the power change threshold for the target area, the server can continuously monitor the current electric quantity uploaded by each electric bicycle in the target area, and push the electric bicycle to the operation and maintenance personnel when the current electric quantity of the electric bicycle is smaller than the power change threshold, so that the operation and maintenance personnel can execute power change on the electric bicycle. The power change threshold may be updated periodically, such as once a week or month, to accommodate the most recent use of the electric bicycle in the target area.

According to the method for determining the power change threshold of the electric bicycle, the reliability of the historical standby power consumption of the first sample electric bicycle, namely the power consumption weight is determined according to the historical order of the first sample electric bicycle, the historical standby power consumption of the first sample electric bicycle is converted into daily standby power consumption, the standby power quantity threshold which enables each electric bicycle in a target area to be kept in a standby state is calculated according to the power consumption weight and the daily standby power consumption, and then the power change threshold for the target area is determined according to the standby power quantity threshold and the running parameters of each second sample electric bicycle in the target area, so that an operation and maintenance person can change the power of the electric bicycle with the power quantity below the power change threshold. According to the embodiment of the application, the power conversion threshold value for the target area is calculated according to the condition of each electric bicycle in the target area, so that the calculated power conversion threshold value can reflect the condition of each electric bicycle in the target area, and the accuracy of the power conversion threshold value is improved.

In one embodiment, as shown in FIG. 2, determining the power consumption weight of the first sample electric bicycle based on each historical order of the first sample electric bicycle in step 104 includes:

Step 202, determining a historical order quantity of the first sample electric bicycle based on each historical order of the first sample electric bicycle.

Step 204, determining an order volume interval to which the historical order volume belongs.

Step 206, determining the power consumption weight of the first sample electric bicycle according to the first preset power consumption weight corresponding to the order quantity interval, wherein the first preset power consumption weight is inversely related to the boundary size of the order quantity interval.

In the embodiment of the application, the power consumption weight of the first sample electric bicycle can be set through the historical order quantity (the quantity of the historical order), so that the influence of the order quantity on the accuracy of the historical standby power consumption provided by the first sample electric bicycle is eliminated through the power consumption weight.

The order quantity interval may be divided in advance, or may be divided according to a historical order quantity of each first sample electric bicycle. Each order quantity interval should be at least 1 in length. Under the condition that the order quantity interval is divided according to the historical order quantity in real time, the influence of inaccurate historical standby power consumption caused by uploading data is smaller as the first sample electric bicycles are more, so that the length of the order quantity interval and the number of the first sample electric bicycles can be inversely proportional.

For example, since the historical standby power consumption of the first sample electric bicycle with the historical order amount of 0 is most accurate, an order amount interval of [0, 1) (the order amount is less than 1 and greater than or equal to 0) may be first divided, and the first preset power consumption weight of the order amount interval may be set to 1. In the case of dividing the order quantity sections in advance, a first preset power consumption weight of each order quantity section may be set according to a boundary size (may be a left boundary or a right boundary) of each order quantity section such that the first preset power consumption weight and the boundary size are inversely related. For example, if each of the pre-divided order amount intervals is [0, 1), [1, 2), [2,3 ], the first preset power consumption weight of [1, 2) may be 0.98 and the first preset power consumption weight of [2, 3) may be 0.96. Under the condition that the order volume intervals are divided according to the historical order volume in real time, the order volume intervals can be ordered from small to large according to the boundary size, and then a first preset power consumption weight corresponding to each order volume interval is determined according to the preset relation between the first preset power consumption weight and the arrangement sequence: for example, a first preset power consumption weight corresponding to the order volume section arranged at the 1 st bit of the queue may be preset to be 1, the 2 nd bit corresponds to 0.98, and the 3 rd bit corresponds to 0.96 … …, if the result of sorting the divided order volume sections according to the boundary sizes from small to large is [0,1 ], [1,4], [4, 7), the first preset power consumption weight of the order volume section [0,1 ] may be made to be 1, the first preset power consumption weight of the order volume section [1,4] is 0.98, and the first preset power consumption weight of the order volume section [4, 7) is 0.96. Other ways of determining the first preset power consumption weight may also be used, which are not particularly limited in the embodiments of the present application.

After the order quantity interval is determined, the number of the historical orders of the first sample electric bicycle can be counted to obtain the historical order quantity, and then a first preset power consumption weight corresponding to the order quantity interval to which the historical order quantity of the first sample electric bicycle belongs is used as the power consumption weight corresponding to the first sample electric bicycle.

According to the method for determining the power change threshold of the electric bicycle, which is provided by the embodiment of the application, according to the first preset power consumption weight of the order volume interval to which the historical order volume of the first sample electric bicycle belongs, the power consumption weight corresponding to the first sample electric bicycle is determined, and the first preset power consumption weight is inversely related to the boundary size of the order volume interval. The more the order quantity is, the more the electric quantity used by the electric bicycle for uploading data after the order is ended is, the more inaccurate the historical standby power consumption of the electric bicycle is, so that the first preset power consumption weight is inversely related to the order quantity interval, the smaller the proportion of the electric bicycle with the larger order quantity is when the standby power consumption threshold value is finally calculated, the accuracy of the standby power consumption threshold value is improved, and the accuracy of the power change threshold value is further improved.

In one embodiment, as shown in FIG. 3, determining the power consumption weight of the first sample electric bicycle based on each historical order of the first sample electric bicycle in step 104 includes:

Step 302, determining each standby interval of the first sample electric bicycle based on each historical order of the first sample electric bicycle.

Step 304, for any standby interval, determining a second preset power consumption weight corresponding to the standby interval according to the length of the standby interval, wherein the length of the standby interval is positively correlated with the second preset power consumption weight.

Step 306, determining the power consumption weight corresponding to the first sample electric bicycle according to the second preset power consumption weight corresponding to each standby interval.

In the embodiment of the application, as the standby time of the electric bicycle is longer, the influence of uploading data to the server on the accuracy of the standby power consumption is smaller, one power consumption weight can be calculated for each standby time of the first sample electric bicycle, and then the power consumption weight for the first sample electric bicycle is obtained according to the power consumption weight of each standby time.

For example, according to each historical order of the first sample electric bicycle, the time when the first sample electric bicycle is not in the ordered running state, namely the standby interval, can be calculated, and the length of each standby interval is obtained. A relation formula of the length of the standby interval and the second preset power consumption weight can be preset, then the length of the standby interval is substituted into the formula, and the second preset power consumption weight of the standby interval is obtained through calculation; or a plurality of length intervals can be preset, a second preset power consumption weight is set for each length interval, and the second preset power consumption weight corresponding to the length interval of the standby interval is used as the second preset power consumption weight corresponding to the standby interval.

The power consumption weight corresponding to the first sample electric bicycle can be obtained according to the second preset power consumption weight corresponding to each standby interval, for example, the average value of each second preset power consumption weight is taken as the power consumption weight, and the median of each second preset power consumption weight is taken as the power consumption weight, which is not particularly limited in the embodiment of the application.

By way of specific example, since the power consumption of the transmission data is negligible when the length of the standby interval is 12 hours or more, the second preset power consumption weight corresponding to the standby interval of 12 hours or more may be set to 1. The relation formula of the length of the other standby interval and the second preset power consumption weight may be set to be that the second preset power consumption weight=the length of the standby interval× (1/60) +0.8, so that the length of the standby interval is in direct proportion to the second preset power consumption weight.

Taking the history time period as 2 days before the present day, the first sample electric bicycle generates the history standby power consumption 1 from 23 time of 1 st day to 5 time of 2 nd day, and generates the history standby power consumption 2 from 7 time of 2 nd day to 8 time, for example, the length of the standby section 1 corresponding to the history standby power consumption 1 is 6 hours, and the length of the standby section 2 corresponding to the history standby power consumption 2 is 1 hour. According to the above formula, the second preset power consumption weight of the standby interval 1 is 0.9, and the second preset power consumption weight of the standby interval 2 is 0.82. The second preset power consumption weights of the standby interval 1 and the standby interval 2 can be averaged to obtain the power consumption weight of the first sample electric bicycle of 0.86.

According to the method for determining the power conversion threshold of the electric bicycle, the second preset power consumption weight of each standby interval is determined according to the length of each standby interval of the first sample electric bicycle, the corresponding power consumption weight of the first sample electric bicycle is determined according to each second preset power consumption weight, and the second preset power consumption weight is positively correlated with the length of each standby interval. The longer the standby time is, the smaller the influence of the electric quantity used by the electric bicycle for uploading data after the order is ended on the standby power consumption is, the more accurate the historical standby power consumption of the electric bicycle is, so that the second preset power consumption weight is positively correlated with the length of the standby interval, the larger the specific gravity occupied by the electric bicycle with the larger length of the standby interval when the standby power consumption threshold is finally calculated is, the accuracy of the standby power consumption threshold is improved, and the accuracy of the power change threshold is further improved.

In one embodiment, as shown in fig. 4, in step 106, determining the daily standby power consumption of each first sample electric bicycle according to the historical standby power consumption of each first sample electric bicycle, includes:

Step 402, determining a standby time length corresponding to the historical standby power consumption for any historical standby power consumption of any first sample electric bicycle.

Step 404, for any first sample electric bicycle, determining the daily standby power consumption corresponding to the first sample electric bicycle according to each historical standby power consumption and the standby time length corresponding to each historical standby power consumption of the first sample electric bicycle.

According to the embodiment of the application, the standby time length corresponding to each historical standby power consumption of the first sample electric bicycle can be obtained, and the daily standby power consumption of the first sample electric bicycle can be calculated accordingly.

For each first sample electric bicycle, the actual standby power consumption of the first sample electric bicycle per day can be calculated according to the standby time corresponding to each historical standby power consumption generated by the first sample electric bicycle. For example, if the history period is 2 days before the present day, the first sample electric bicycle generates the history standby power consumption 1 from 23 on the 1 st day to 5 on the 2 nd day, and generates the history standby power consumption 2 from 7 on the 2 nd day to 8 days, the actual standby power consumption of the first sample electric bicycle on the 1 st day is 1/6×history standby power consumption 1, and the actual standby power consumption on the 2 nd day is 5/6×history standby power consumption 1+history standby power consumption 2.

After the daily actual standby power consumption of the first sample electric bicycle is obtained, the daily standby power consumption can be calculated according to the daily actual standby time of the first sample electric bicycle. The ratio of the actual standby power consumption to the actual standby time length can be used as the standby power consumption of the first sample electric bicycle per hour, and the standby power consumption per hour is multiplied by the number of hours (24) per day to obtain the daily standby power consumption. In the above example, the first sample electric bicycle has 24× (1/6×history standby power consumption 1)/1 on day 1 and 24× (5/6×history standby power consumption 1+history standby power consumption 2)/6 on day 2.

According to the method for determining the power change threshold of the electric bicycle, the power consumption (daily standby power consumption) required by 24 hours of standby of the first sample electric bicycle is calculated according to the standby time length corresponding to each historical standby power consumption of the first sample electric bicycle, so that the standby power quantity threshold can be calculated according to the daily standby power consumption. Because the power change is generally carried out once a day, the standby power threshold is calculated according to the daily standby power consumption, so that the server can ensure that before the power of the electric bicycle is reduced to the minimum power required by daily standby, the server informs operation and maintenance personnel to change the power of the electric bicycle, the situation that the electric bicycle cannot be relocated due to the fact that the power of the electric bicycle is exhausted is avoided, and the accuracy of the standby power threshold and the power change threshold is improved.

In one embodiment, as shown in fig. 5, in step 108, determining a power change threshold for the target area according to the standby power threshold and the driving parameters of each second sample electric bicycle in the target area includes:

Step 502, determining the expected order quantity aiming at the target area according to the running parameters of each second sample electric bicycle in the target area.

In step 504, a power change threshold for the target area is determined according to the expected order amount and the standby power threshold, and the power change threshold is positively correlated with the expected order amount.

In the embodiment of the application, in order to enable the electric bicycle to continue to operate while the electric quantity of the electric bicycle is reduced below the electricity changing threshold and the operation and maintenance personnel starts to change the electricity of the electric bicycle, the expected order quantity of the target area can be obtained according to the prediction of each second sample electric bicycle, and the electricity changing threshold can be set according to the expected order quantity. The expected order quantity refers to the average number of orders that can be received per electric bicycle per day in the target area.

For example, the daily vehicle effect (i.e. the ratio of the sum of the running times of each second sample electric bicycle to the number of second sample electric bicycles) of the target area can be calculated according to the running times of the running parameters of each second sample electric bicycle, so as to predict the expected order amount of the present day according to the change trend of the daily vehicle effect (for example, predicting by using a trained neural network, or predicting according to the relationship between the deduced vehicle effect and time change, etc.). Or the vehicle effect in the target area within a period of time can be averaged to obtain the expected order quantity of the present day, which is not particularly limited in the embodiment of the present application.

A coefficient can be set for each expected order quantity, and then the coefficient is multiplied by the standby electric quantity threshold value to obtain the power change threshold value of the target area. Or the power-change threshold of the target area may be determined in other manners, which is not specifically limited in the embodiment of the present application.

It should be noted that, since the user will usually be related to the remaining power of the electric bicycle when riding the electric bicycle, the determined power change threshold may be partially adjusted based on the running parameters of each second sample electric bicycle. For example, the electric quantity of each second sample electric bicycle at each start of running can be obtained, and then the ratio of the total number of running times of which the electric quantity is near the electricity change threshold value at the start of running and the sum of all running times is counted. If the ratio is too small (for example, less than a certain preset threshold, for example, 0.2), it indicates that the power-changing threshold is too low, and setting the power-changing threshold on the value will instead reduce the utilization rate of the electric bicycle, so that the power-changing threshold can be properly replaced and the ratio can be recalculated until the ratio meets the requirement.

According to the method for determining the electric bicycle power change threshold, the expected order quantity is determined according to the driving parameters, and the power change threshold is set according to the expected order quantity and the standby power threshold, so that the power of the electric bicycle can continue to operate when the power of the electric bicycle falls below the power change threshold but is still above the standby power threshold, and the utilization rate of the electric bicycle is improved.

In one embodiment, as shown in fig. 6, in step 504, determining a power change threshold for the target area according to the expected order volume and the standby power threshold includes:

Step 602, determining the order power consumption for the target area according to the driving parameters of each second sample electric bicycle in the target area.

In step 604, a power change threshold for the target area is determined according to the order power consumption, the expected order amount, and the standby power threshold.

According to the embodiment of the application, the order power consumption required by each electric bicycle to complete one order expectation in the target area can be calculated, and the electricity change threshold is determined according to the order power consumption, the expected order quantity and the standby power threshold.

For example, the running power consumption in the running parameters may be acquired, and an average value of the running power consumption may be taken as the order power consumption. Or in consideration of ensuring that the user can smoothly perform a long-distance order, when the electric bicycle is used, the electric quantity should not be reduced below a standby electric quantity threshold, the driving mileage corresponding to each driving power consumption can be obtained, and the average value of the driving power consumption with the driving mileage greater than the mileage threshold is taken as the order power consumption.

The method comprises the steps of estimating the order quantity (such as 1/2 and 1/3 of the expected order quantity) when the electric quantity of the electric bicycle falls below a power change threshold according to the expected order quantity, multiplying the order quantity by the power consumption of the order, and summing the multiplied result and a standby electric quantity threshold to obtain the power change threshold. Or, referring to the method in the foregoing embodiment, according to the running parameter of each second sample electric bicycle, determining the ratio of the total number of running times when the electric quantity of the electric bicycle falls to the vicinity of the power change threshold to the sum of all running times, obtaining the order quantity when the electric quantity of the electric bicycle falls below the power change threshold according to the product of the ratio and the expected order quantity, multiplying the order quantity by the power consumption of the order, and summing the multiplied result and the standby power quantity threshold to obtain the power change threshold. The power change threshold may also be calculated in other manners, which is not particularly limited in the embodiment of the present application.

Referring to fig. 7, an effect diagram of an embodiment of the present application is shown. In fig. 7, the horizontal axis refers to the remaining power of the electric bicycle, and the vertical axis refers to the ratio of the number of electric bicycles having the remaining power to the number of all electric bicycles. In the prior art, the power conversion threshold is generally set at 44%, that is, each electric bicycle covered by a transverse frame ① in the figure, which causes great waste. By the scheme provided by the embodiment of the application, different power conversion thresholds (21% for the A city and 22% for the B city) can be calculated for different cities, and the electric bicycle needing power conversion is compressed to the range covered by the mullion ②, so that the utilization rate of the electric bicycle is greatly improved.

According to the method for determining the electricity change threshold of the electric bicycle, the order power consumption is determined according to the driving parameters, and the electricity change threshold is set according to the expected order quantity, the order power consumption and the standby electric quantity threshold, so that the electric quantity of the electric bicycle can continue to operate when the electric quantity of the electric bicycle falls below the electricity change threshold but is still above the standby electric quantity threshold, and the utilization rate of the electric bicycle is improved.

In one embodiment, the method further comprises:

aiming at any target electric bicycle in the target area, under the condition that the target electric bicycle is in a running state, and the current electric quantity of the target electric bicycle is larger than a standby electric quantity threshold value and smaller than a power change threshold value, first alarm information is displayed, and the first alarm information is used for indicating that the target electric bicycle needs to be changed. Or alternatively

In the embodiment of the application, after the power-changing threshold and the standby power threshold are determined, when a user uses any target electric bicycle in the target area, the server can monitor the target electric bicycle according to the real-time power (current power) uploaded by the target electric bicycle. When the current electric quantity of the target electric bicycle is smaller than the power change threshold value but larger than the standby electric quantity threshold value, the electric quantity of the target electric bicycle is indicated to be lower, and the order can be completed continuously. At this time, the server may generate the first alarm information, and send the first alarm information to the target electric bicycle for playing (through a screen or a speaker of the target electric bicycle) so as to remind the user that the target electric bicycle may need to change electricity, but the target electric bicycle may still continue to run.

In the case that the current power of the target electric bicycle is smaller than or equal to the standby power threshold, the target electric bicycle is indicated to have to be subjected to power change, otherwise, the power consumption can be caused to be unable to be positioned. The server can generate second alarm information and send the second alarm information to the target electric bicycle for playing so as to remind the user that the target electric bicycle cannot continue running and the user needs to replace the electric bicycle. The server can also instruct the target electric bicycle to actively lock and stop and enter a standby state when the user pauses running for the first time after receiving the alarm information, so that the continuous consumption of electric quantity is avoided.

According to the method for determining the power change threshold of the electric bicycle, when the electric quantity of any electric bicycle is lower than the power change threshold but higher than the standby electric quantity threshold, the first alarm information is displayed to indicate that the target electric bicycle needs to change electricity, and when the electric quantity of the electric bicycle is lower than the standby electric quantity threshold, the second alarm information is displayed to indicate that the target electric bicycle cannot continue running, and the current electric quantity state of the electric bicycle can be reminded to a user.

In one embodiment, as shown in fig. 8, the method further includes:

Step 804, determining electric quantity display information aiming at the target electric bicycle according to the battery parameter of the target electric bicycle, the battery electric quantity of the target electric bicycle and the standby electric quantity threshold value, and displaying the electric quantity display information.

In the embodiment of the application, for any electric bicycle (target electric bicycle) in the target area, the electric quantity display information required to be displayed for the user can be determined according to the current battery electric quantity of the target electric bicycle, the determined standby electric quantity threshold value and the battery parameters of the target electric bicycle. The battery parameters may include a battery state of health, a battery discharge efficiency, and the like, and the power display information may include a battery power of the target electric bicycle, a standby power threshold, a power difference between the battery power and the standby power threshold, and a mileage that the electric bicycle may continue to travel.

The difference between the battery power of the target electric bicycle and the standby power threshold can be used as a power difference value, so that according to the battery parameter of the target electric bicycle, the corresponding driving mileage of the power difference value of the target electric bicycle is calculated, and the mileage is used as power display information of the target electric bicycle to be displayed to a user.

In addition, according to the order power consumption and the electric quantity difference in the foregoing embodiments, the number of orders corresponding to the large electric quantity difference is calculated, and the number of orders is also displayed to the user as electric quantity display information, so that the user can know how many mileage the electric bicycle can travel and how many orders are executed before the electric bicycle cannot be ridden, and the user can conveniently select a proper electric bicycle to ride.

According to the method for determining the power change threshold of the electric bicycle, the power display information is generated according to the standby power threshold, the battery parameters and the battery power, and the power display information is displayed, so that a user can know the current power related information of the electric bicycle, and the user can conveniently select a proper electric bicycle to ride.
