[0055] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0056] It should be noted that the terms "including" and "having" and any variations thereof in the embodiments of the present application and the accompanying drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0057] It is understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first line length value may be referred to as a second line length value, and similarly, a second line length value may be referred to as a first line length value. Both the first line length value and the second line length value are line length values, but they are not the same line length value. The term "plurality" used in this application refers to two or more. The term "and / or" used in this application refers to one of the schemes, or any combination of multiple schemes.

[0058] In the process of charging a car with a charging pile, both the charging pile and the vehicle will generate a certain amount of power loss. However, the user side is unable to evaluate the pros and cons of the power loss generated by this charging at different charging stations or charging piles, and is unable to perceive the pros and cons of the comparative benefits of charging power loss assessment in advance. This may lead to unsatisfactory power loss costs on the end user's charging bill and cause complaints, affecting the user's actual charging experience, and affecting user retention and satisfaction.

[0059] The current charging station recommendation algorithm does not consider the recommended charging stations from the perspective of comparing the power loss generated during the charging process. The operating platform is also unable to predict the differences in power loss among charging stations recommended to users in advance, and is unable to plan charging stations that generate less power loss for users in advance, thereby failing to provide better services to users.

[0060] The embodiments of the present application provide a charging site evaluation method, device, electronic device, and storage medium, so that users can know the power loss advantages and disadvantages of multiple charging sites in advance, thereby improving the user's charging experience and satisfaction.

[0061] See also Figure 1 , Figure 1 Schematic diagram of an application scenario of a charging station evaluation method disclosed in an embodiment of the present application. Figure 1 As shown, the charging site evaluation method can be applied to a server 110 , and the application scenario includes the server 110 , a terminal device 120 , a charging site 130 , and a charging device 140 .

[0062] The server 110 establishes a communication connection with one or more terminal devices 120 . Optionally, the server 110 may also establish a communication connection with one or more charging sites 130 , respectively, to perform data transmission with the terminal devices 120 and the charging sites 130 .

[0063] The server 110 may be used to process the charging request sent by the terminal device 120 and the charging data sent by the charging station 130. Optionally, the server 110 may include but is not limited to a hardware server, a cloud server, etc., which is not specifically limited in the embodiment of the present application. The server 110 may be an independent server device or a server cluster composed of multiple server devices.

[0064] Optionally, the terminal device 120 may include but is not limited to a mobile phone, a tablet computer, a smart wearable device or a vehicle-mounted terminal. For example, the terminal device 120 may be a personal electronic device of the vehicle owner, or an electronic device installed in the vehicle, which is not limited here. Optionally, the terminal device 120 may run a target application, through which the target application may communicate with the server 110 and send a charging request to the server 110.

[0065] The charging site 130 may be provided with one or more charging devices 140 , which may be used to charge the vehicle and send charging data to the server 110 .

[0066] Optionally, the charging device 140 may be a DC charging device or an AC charging device, which is not specifically limited in the present embodiment. For example, the charging device 140 may be a DC charging pile or an AC charging pile.

[0067] In the embodiment of the present application, the terminal device 120 may send a charging request to the server 110, and the server 110 receives the charging request sent by the terminal device 120. The server 110 determines the charging site to be evaluated based on the charging request. The server 110 may determine the target power loss evaluation result corresponding to the charging site 130, and the target power loss evaluation result is used to indicate the charging loss situation corresponding to the charging site 130. The server sends the recommended site reference information including the target power loss evaluation result to the terminal device 120. The terminal device 120 receives and outputs the recommended site reference information.

[0068] For example, Figure 2 A timing diagram of a charging station evaluation method in an embodiment.

[0069] The charging station evaluation method may include the following steps:

[0070] 1. The terminal device sends a charging request to the server;

[0071] 2. The server receives the charging request sent by the terminal device;

[0072] 3. The server determines the charging site to be evaluated based on the charging request;

[0073] 4. The server determines the target power loss assessment result corresponding to the charging station;

[0074] 5. The server sends the recommended site reference information containing the target power loss assessment results to the terminal device.

[0075] Please read further Figure 3 , Figure 3 1 is a flow chart of a charging station evaluation method disclosed in an embodiment of the present application, and the charging station evaluation method can be applied to the above-mentioned server 110. Figure 3 As shown, the charging station evaluation method may include the following steps:

[0076] Step 310: receiving a charging request sent by a terminal device.

[0077] When the user needs to charge the vehicle, the user can send a charging request to the server through the terminal device, and the server can receive the charging request sent by the terminal device.

[0078] Optionally, the charging request may include one or more information such as identification information, vehicle model, remaining power of the vehicle, current location information, etc., which is not specifically limited in the embodiments of the present application. Among them, identification information may refer to information used to uniquely identify a terminal device, or information used to uniquely identify a user's identity. For example, identification information may include a device ID (Identifier) ​​of a terminal device, a user account logged in on the terminal device, etc.; a vehicle model may include but is not limited to a vehicle manufacturer, a vehicle category, a vehicle configuration, etc.; and current location information may be used to indicate the current geographic location of the vehicle.

[0079] Step 320: Determine a charging site to be evaluated according to the charging request.

[0080] The server may receive a charging request sent by the terminal device, and determine one or more charging sites to be evaluated based on the charging request.

[0081] In some embodiments, the server may determine the charging site to be evaluated based on the current location coordinates contained in the charging request sent by the terminal device. Specifically, the server may calculate the distance between the current vehicle and each charging site based on the current location coordinates contained in the charging request sent by the terminal device and the location coordinates corresponding to each pre-stored charging site. Optionally, the server may sort the charging sites from near to far according to the distance from the vehicle, and determine the charging sites ranked in the top N as the charging sites to be evaluated, where N may be a positive integer. By determining the charging site to be evaluated based on the distance between each charging site and the vehicle, it is possible to ensure that the charging site to be evaluated is within the reach of the vehicle, thereby avoiding the situation where the remaining power of the vehicle is exhausted during driving due to the long distance.

[0082] In some embodiments, the server may query the user's corresponding historical charging sites from the memory according to the identification information contained in the charging request sent by the terminal device, and determine the historical charging sites as the charging sites to be evaluated. By using the user's historical charging sites as the charging sites to be evaluated, the user's charging habits can be fully considered, thereby improving the user's charging experience and satisfaction.

[0083] In some embodiments, the charging request may also include a budgeted fee, and the user may input the budgeted fee corresponding to the charging in the terminal device, which may represent the maximum charging fee that the user can accept. The server may determine the charging site to be evaluated based on the budgeted fee included in the charging request sent by the terminal device. Specifically, the server may calculate the charging power corresponding to each charging site based on the pre-stored electricity prices corresponding to each charging site and the budgeted fee included in the charging request sent by the terminal device, and determine the charging site with a charging power greater than or equal to the power threshold as the charging site to be evaluated. Among them, the power threshold may be determined based on the remaining power of the vehicle, the rated power, etc. The charging power corresponding to each charging site is calculated by the budgeted fee corresponding to the charging input by the user, and the charging site with a charging power greater than or equal to the power threshold is determined as the charging site to be evaluated, which can ensure the charging power of the vehicle while meeting the user's expectations, thereby improving the user's charging experience and satisfaction.

[0084] Step 330: determine a target power loss assessment result of the charging site, where the target power loss assessment result is used to indicate the charging loss situation of the charging site.

[0085] In some embodiments, after the server determines the charging site to be evaluated, the server may determine a target power loss assessment result according to the indicator values ​​corresponding to the charging site to be evaluated and one or more power loss assessment factors.

[0086] The power loss assessment factor may refer to a factor that can assess the charging loss of a charging station. Optionally, the power loss assessment factor may include but is not limited to one or more of the length of the charging line, the ambient temperature, the charging voltage, and the comprehensive performance of the charging pile.

[0087] The charging line length may refer to the line length of the charging equipment at the charging station. For example, the charging line length may refer to the length of the power transmission line between the charging gun and the connected charging pile.

[0088] The ambient temperature may refer to the temperature of the environment in which the charging station is located, and the ambient temperature may be detected by a temperature detection device in the charging station. Optionally, the temperature detection device may include a temperature sensor, an infrared thermometer, a resistance temperature detector, etc., which is not specifically limited in the embodiments of the present application.

[0089] In some embodiments, the temperature detection device may detect the ambient temperature of the charging station at preset intervals.

[0090] The charging voltage may refer to the voltage output by the charging device in the charging station.

[0091] The comprehensive performance of a charging pile may refer to the charging efficiency of the charging equipment used to characterize a charging station. The charging efficiency refers to the proportion of electrical energy input to the charging equipment that can be effectively converted into chemical energy stored in the vehicle battery.

[0092] As an optional implementation, the server may calculate the power loss assessment score corresponding to each charging site to be evaluated based on the index values ​​corresponding to the multiple charging sites to be evaluated and one or more power loss assessment factors, and determine the power loss assessment score corresponding to each charging site to be evaluated as the target power loss assessment result. Optionally, the larger the power loss assessment score corresponding to the charging site to be evaluated, the smaller the charging loss generated by the charging site to be evaluated during the charging process, and the better the charging effect of the charging equipment in the charging site to be evaluated. By calculating the power loss assessment score corresponding to each charging site to be evaluated based on the index values ​​corresponding to the multiple charging sites to be evaluated and one or more power loss assessment factors, the charging loss situation of each charging site to be evaluated can be quantified, and the user can intuitively see the pros and cons of the power loss of each charging site to be evaluated, thereby improving the user's charging experience and satisfaction.

[0093] Further, multiple power loss levels may be pre-set, and each power loss level may have a corresponding power loss assessment score range. The server may divide the power loss assessment scores corresponding to each charging station to be evaluated according to the pre-set power loss level, determine the power loss level corresponding to each charging station to be evaluated, and determine the power loss level corresponding to each charging station to be evaluated as the target power loss assessment result. Exemplarily, the higher the power loss level, the greater the power loss corresponding to the charging station. For example, the server may pre-set five power loss levels, the power loss assessment score range corresponding to the first power loss level is 0 to 0.2, the power loss assessment score range corresponding to the second power loss level is 0.2 to 0.4, the power loss assessment score range corresponding to the third power loss level is 0.4 to 0.6, the power loss assessment score range corresponding to the fourth power loss level is 0.6 to 0.8, and the power loss assessment score range corresponding to the fifth power loss level is 0.8 to 1. When the power loss assessment score corresponding to the charging station to be evaluated is 0.9, it can be determined that the power loss level corresponding to the charging station to be evaluated is the fifth power loss level. By dividing the power loss assessment scores corresponding to each charging station to be evaluated into power loss levels, users can more intuitively see the power loss advantages and disadvantages of each charging station to be evaluated, thereby improving the user's charging experience and satisfaction.

[0094] Step 340: Send recommended site reference information including target power loss assessment results to the terminal device.

[0095] After determining the target power loss assessment result, the server may send recommended site reference information including the target power loss assessment result to the terminal device.

[0096] As an implementation method, the server may directly use the target power loss assessment results corresponding to each charging station to be assessed as reference information for recommending stations.

[0097] The terminal device may receive the recommended site reference information including the target power loss assessment result sent by the server and display the recommended site reference information. The recommended site reference information may be used to display the assessment results corresponding to the recommended multiple charging sites to the user.

[0098] As an optional implementation, after receiving the recommended site reference information, the terminal device can directly display the target power loss assessment results corresponding to each charging site to be evaluated.

[0099] Exemplarily, the target power loss assessment result includes the power loss level corresponding to the charging site to be assessed. The terminal device can display the power loss level corresponding to each charging site to be assessed based on the received recommended site reference information. Exemplarily, the target power loss assessment result includes the power loss assessment score corresponding to the charging site to be assessed, and the terminal device can display the power loss assessment score corresponding to each charging site to be assessed based on the received recommended site reference information. By sending the power loss level and power loss assessment score corresponding to each charging site to be assessed to the terminal device, the user can intuitively see the charging loss situation of each charging site to be assessed, thereby improving the user's charging experience and satisfaction.

[0100] Furthermore, the server may sort the multiple charging stations to be evaluated in descending order of the power loss evaluation scores, obtain ranking results corresponding to the multiple charging stations to be evaluated, and send recommended station reference information including the ranking results to the terminal device; the terminal device may receive the recommended station reference information including the ranking results and display the ranking results. By displaying the ranking results of the power loss evaluation scores corresponding to each charging station to be evaluated, the power loss pros and cons corresponding to each charging station to be evaluated can be intuitively displayed.

[0101] In some embodiments, the server may calculate the estimated power loss cost based on the target power loss assessment result corresponding to the charging site to be assessed, and send the recommended site reference information to the terminal device, the recommended site reference information including the estimated power loss costs corresponding to the multiple charging sites to be assessed. The terminal device may display the estimated power loss costs corresponding to the multiple charging sites to be assessed based on the received recommended site reference information. Exemplarily, the target power loss assessment result includes the estimated power loss corresponding to the multiple charging sites to be assessed, and the server may calculate the estimated power loss cost corresponding to each charging site to be assessed based on the product of the electricity price corresponding to each charging site to be assessed and the estimated power loss, and send the recommended site reference information including the estimated power loss costs corresponding to the multiple charging sites to be assessed to the terminal device. Among them, the estimated power loss may refer to the estimated amount of power lost by the vehicle during charging at the charging site to be assessed. The terminal device may receive the recommended site reference information and display the estimated power loss costs corresponding to the multiple charging sites to be assessed. The estimated electricity loss costs corresponding to each charging station are displayed to users through terminal devices. Users can know the electricity loss costs they need to pay in advance, ensuring the user's right to know. Users can choose a suitable charging station according to their own budget, thereby improving the user's charging experience and satisfaction.

[0102] As another implementation, the server may determine the comprehensive evaluation results corresponding to each charging station to be evaluated based on the target power loss evaluation results corresponding to each charging station to be evaluated and other evaluation results, and use the comprehensive evaluation results corresponding to each charging station to be evaluated as reference information for recommended stations.

[0103] Among them, other evaluation results may include but are not limited to the charging price ranking corresponding to each charging station to be evaluated, the distance ranking between each charging station to be evaluated and the vehicle, etc., which is not specifically limited in this embodiment of the present application.

[0104] In some embodiments, the server may determine the comprehensive evaluation score corresponding to each charging station to be evaluated according to the multiple evaluation results and corresponding weights corresponding to each charging station to be evaluated; and sort the multiple charging stations to be evaluated in order from high to low according to the comprehensive evaluation scores to obtain the comprehensive ranking results corresponding to the multiple charging stations to be evaluated; further, the server may send the recommended station reference information containing the comprehensive ranking results to the terminal device. The terminal device may receive the recommended station reference information containing the comprehensive ranking results and display the comprehensive ranking results. By considering multiple evaluation results, the recommended station reference information can be made more comprehensive and reliable.

[0105] Among them, multiple evaluation results refer to evaluation results determined based on evaluation factors other than power loss. Optionally, multiple evaluation results may include but are not limited to the charging price ranking corresponding to each charging station to be evaluated, the distance ranking between each charging station to be evaluated and the vehicle, etc. The embodiment of the present application does not make specific limitations on this.

[0106] The weights corresponding to multiple evaluation results can be set according to user needs, and the embodiments of the present application do not impose specific limitations on this.

[0107] In some embodiments, the server may perform a weighted sum or weighted average of the various evaluation results corresponding to the charging station to be evaluated and the corresponding weights to obtain a comprehensive evaluation score corresponding to the charging station to be evaluated. By weighted averaging or weighted summing the multiple evaluation results corresponding to the charging station to be evaluated and integrating the multiple evaluation results, the singleness of the reference information of the recommended station can be avoided.

[0108] In the embodiment of the present application, the server receives a charging request sent by a terminal device; according to the charging request, determines a charging site to be evaluated; determines a target power loss evaluation result corresponding to the charging site; the target power loss evaluation result is used to indicate the charging loss situation corresponding to the charging site; and sends recommended site reference information containing the target power loss evaluation result to the terminal device. In the embodiment of the present application, the server can determine the target power loss evaluation result corresponding to the charging site, and send the recommended site reference information containing the target power loss evaluation result to the terminal device, which ensures the user's right to know and gives the user's usage expectations. The user can know the power loss advantages and disadvantages of multiple charging sites in advance, which improves the user's charging experience and satisfaction.

[0109] In some embodiments, Figure 4 As shown, the step server determines the target power loss assessment result according to the indicator values ​​corresponding to the charging station and one or more power loss assessment factors, which may include the following steps:

[0110] Step 410, obtaining index values ​​corresponding to the charging station and one or more power loss assessment factors, wherein the one or more power loss assessment factors include at least one of the following: charging line length, ambient temperature, charging voltage, and comprehensive performance of the charging pile.

[0111] In some embodiments, the server may query the indicator value corresponding to the charging site to be evaluated and the power loss assessment factor from the memory according to the correspondence between the site identifier corresponding to the charging site to be evaluated and the power loss assessment factor. The site identifier corresponding to the charging site to be evaluated can be used to uniquely identify the charging site.

[0112] In some embodiments, the charging equipment in the charging station may send indicator values ​​corresponding to the power loss assessment factors to the server at preset time intervals. The server may receive the indicator values ​​and store them in correspondence with the station identifier corresponding to the charging station.

[0113] In some embodiments, after the server obtains the index values ​​corresponding to the charging station and one or more power loss assessment factors, the server may perform positive processing on the index values ​​corresponding to each charging station and the power loss assessment factor, and obtain a positively correlated index value with the power loss assessment factor, if the power loss assessment factor is not positively correlated with the target power loss assessment result. Then, the target power loss assessment result is determined based on the positively correlated index values ​​corresponding to each charging station to be assessed and the multiple power loss assessment factors.

[0114] Among them, the positive correlation means that when the index value corresponding to the power loss assessment factor increases, the target power loss assessment result also increases accordingly, which is a positive correlation influence. Furthermore, the positive correlation means that when the index value corresponding to the power loss assessment factor increases, the power loss assessment score also increases accordingly, which is a positive correlation influence on the power loss assessment score.

[0115] In some embodiments, the power loss assessment factor includes the length of the charging line. Since the longer the charging line is, the higher the power loss generated during the charging process is, the charging line length is negatively correlated with the power loss assessment score, not positively correlated. Therefore, the indicator value of the charging line length needs to be positively processed. The server can calculate the reciprocal of the first line length value corresponding to the charging station to obtain the second line length value corresponding to the charging station. The second line length value is the positive line length value obtained after the first line length value is positively processed.

[0116] Among them, the first line length value is the indicator value corresponding to the charging station and the charging line length; the second line length value can be used to determine the target power loss assessment result of the charging station.

[0117] For example, the second line length value corresponding to the charging station can be calculated with reference to the following formula (1):

[0118]

[0119] Among them, x i A first line length value may be indicated; A second line length value may be indicated.

[0120] In some embodiments, the power loss assessment factor includes the ambient temperature, such as Figure 5 As shown, the step of performing positive processing on the indicator value of the ambient temperature may include steps 510 to 520.

[0121] Step 510, calculating the temperature distance between the first ambient temperature value corresponding to the charging station and the target temperature range; the first ambient temperature value is an index value corresponding to the charging station and the ambient temperature.

[0122] The first ambient temperature value may be an ambient temperature value detected in real time by a temperature detection device in the charging station to be evaluated. The target temperature range may include a maximum temperature and a minimum temperature. For example, the target temperature range may be a temperature range that has a smaller impact on the power loss generated during the charging process. The server may calculate the temperature distance between the first ambient temperature value corresponding to the charging station to be evaluated and the target temperature range. The temperature distance may refer to the difference between the first ambient temperature value corresponding to the charging station to be evaluated and the target temperature range. The larger the temperature distance, the greater the difference between the first ambient temperature value corresponding to the charging station to be evaluated and the target temperature range, and the greater the impact on the power loss during the charging process, which will result in more power loss.

[0123] In some embodiments, the server may determine whether the first ambient temperature value corresponding to the charging station to be evaluated is within the target temperature range. If the first ambient temperature value is not within the target temperature range, and the first ambient temperature value corresponding to the charging station is less than the minimum temperature value, the server may calculate the minimum temperature value minus the first ambient temperature value corresponding to the charging station to obtain the temperature distance corresponding to the charging station.

[0124] If the first ambient temperature value is not within the target temperature range and the first ambient temperature value corresponding to the charging station is greater than the maximum temperature, the server can calculate the first ambient temperature value corresponding to the charging station minus the maximum temperature to obtain the temperature distance corresponding to the charging station.

[0125] When the first ambient temperature value corresponding to the charging station is within the target temperature range, the server may determine that the temperature distance corresponding to the first charging station is zero.

[0126] For example, the maximum temperature value may be represented as b, the minimum temperature value may be represented as a, and the first ambient temperature value corresponding to the charging station may be represented as x. i , then when the first ambient temperature value corresponding to the charging station is less than the minimum temperature value, the temperature distance corresponding to the charging station can be expressed as ax i ; When the first ambient temperature value corresponding to the charging station is greater than the maximum temperature, the temperature distance corresponding to the charging station can be expressed as x i -b.

[0127] Step 520, determining a second ambient temperature value corresponding to the charging station according to the temperature distance corresponding to the charging station; the second ambient temperature value is used to determine a target power loss assessment result of the charging station.

[0128] In some embodiments, the server may use the maximum value of the temperature distances corresponding to multiple charging sites as the first maximum difference value; the server may calculate the first ratio between the temperature distance corresponding to each charging site and the first maximum difference value; and subtract the second ratio corresponding to each charging site from 1 to obtain the second ambient temperature value corresponding to each charging site.

[0129] For example, the first maximum difference value may be represented as M, then M=max{a-min{x i},max{x i}-b}, where min{x i} may represent the minimum value of the first ambient temperature values ​​corresponding to multiple charging stations, max{x i} may represent the maximum value of the first ambient temperature values ​​corresponding to multiple charging stations.

[0130] The second ambient temperature value corresponding to the charging station can be calculated by referring to the following formula (2):

[0131]

[0132] in, It can represent the second ambient temperature value corresponding to the i-th charging station.

[0133] As another optional implementation, the server may calculate the estimated power loss corresponding to each charging site to be evaluated based on the indicator values ​​corresponding to the multiple charging sites to be evaluated and one or more power loss assessment factors, and calculate the estimated power loss cost corresponding to each charging site to be evaluated based on the estimated power loss corresponding to each charging site to be evaluated and the pre-stored electricity price corresponding to each charging site, and determine the estimated power loss cost corresponding to each charging site to be evaluated as the target power loss assessment result.

[0134] In some embodiments, after the server determines the charging site to be evaluated, the server may determine a target power loss assessment result for the charging site to be evaluated based on historical power loss assessment results corresponding to the charging site to be evaluated.

[0135] Optionally, the historical power loss assessment results corresponding to the charging site to be evaluated may include the historical power loss level corresponding to the charging site, the historical assessment score corresponding to the charging site, the historical power loss cost corresponding to the charging site, etc., which is not limited to this embodiment of the present application.

[0136] Taking the historical power loss assessment result as the historical power loss level corresponding to the charging site to be evaluated as an example, the server can determine the power loss level that appears most times in the historical power loss levels corresponding to the charging site to be evaluated as the power loss level corresponding to the charging site to be evaluated, and use the power loss level corresponding to the charging site as the target power loss assessment result.

[0137] By considering the user's historical evaluation results, the user's personal habits can be fully taken into account, thereby improving the user's charging experience and satisfaction.

[0138] In the embodiment of the present application, the server can calculate the temperature distance between the first ambient temperature value corresponding to the charging station and the target temperature range; the first ambient temperature value is the index value corresponding to the charging station and the ambient temperature. Then, the server can determine the second ambient temperature value corresponding to the charging station according to the temperature distance corresponding to the charging station; the second ambient temperature value is used to determine the target power loss assessment result of the charging station. By converting the first ambient temperature value into the second ambient temperature value, the first ambient temperature value is positively correlated with the target power loss assessment result.

[0139] In some embodiments, the power loss assessment factor includes a comprehensive performance index of the charging pile, such as Figure 6 As shown, the step of performing positive processing on the comprehensive performance index of the charging pile may include steps 610 to 620.

[0140] Step 610, calculating the absolute value of the difference between the first charging pile comprehensive performance value corresponding to the charging station and the target charging pile comprehensive performance value.

[0141] Among them, the first charging pile comprehensive performance value may refer to the index value corresponding to the charging station to be evaluated and the charging pile comprehensive performance index; the target charging pile comprehensive performance value may refer to the temperature range that has a smaller impact on the power loss generated during the charging process. The server can calculate the absolute value of the difference between the first charging pile comprehensive performance value corresponding to the charging station and the target charging pile comprehensive performance value. The absolute value of the difference may refer to the difference between the first charging pile comprehensive performance value corresponding to the charging station to be evaluated and the target charging pile comprehensive performance value. The larger the absolute value of the difference, the greater the difference between the first charging pile comprehensive performance value corresponding to the charging station to be evaluated and the target charging pile comprehensive performance value, the greater the impact on the power loss during the charging process, and more power loss will be generated.

[0142] For example, the comprehensive performance value of the first charging pile corresponding to the i-th charging station to be evaluated is x i , the target charging pile comprehensive performance value is x best The absolute value of the difference between the comprehensive performance value of the first charging pile corresponding to the i-th charging station to be evaluated and the comprehensive performance value of the target charging pile can be expressed as |x i -x best |.

[0143] Step 620, determining a second charging pile comprehensive performance value corresponding to the charging station according to the absolute value of the difference corresponding to the charging station; the second charging pile comprehensive performance value is used to determine a target power loss assessment result of the charging station.

[0144] In some embodiments, the server may use the maximum value of the absolute values ​​of the differences corresponding to multiple charging stations to be evaluated as the second maximum difference value; calculate the ratio between the absolute value of the differences corresponding to each charging station to be evaluated and the second maximum difference value; subtract the first ratio corresponding to each charging station to be evaluated from 1 to obtain the second charging pile comprehensive performance value corresponding to each charging station to be evaluated.

[0145] Exemplarily, the second maximum difference value may be represented as M, then M=max{|x i -x best |}, the comprehensive performance value of the second charging pile can be calculated by referring to the following formula (3):

[0146]

[0147] in, It can represent the comprehensive performance value of the second charging pile corresponding to the i-th charging station to be evaluated.

[0148] In the embodiment of the present application, the server can calculate the absolute value of the difference between the first charging pile comprehensive performance value corresponding to the charging site to be evaluated and the target charging pile comprehensive performance value; determine the second charging pile comprehensive performance value corresponding to the charging site to be evaluated according to the absolute value of the difference corresponding to the charging site to be evaluated; the second charging pile comprehensive performance value is used to determine the target power loss evaluation result of the charging site to be evaluated. By converting the first charging pile comprehensive performance value into the second charging pile comprehensive performance value, the first charging pile comprehensive performance value is forward-oriented, so that the first charging pile comprehensive performance value is positively correlated with the target power loss evaluation result.

[0149] In some embodiments, after performing positive normalization processing on the index values ​​corresponding to multiple charging stations to be evaluated and one or more power loss assessment factors, the server may perform normalization processing on the positive normalized index values ​​corresponding to each charging station to be evaluated and the power loss assessment factor, so as to convert the index value corresponding to the power loss assessment factor into the numerical range corresponding to the power loss assessment factor. Then, the server may determine the power loss assessment result corresponding to each charging station to be evaluated according to the standardized index values ​​corresponding to each charging station to be evaluated and the multiple power loss assessment factors.

[0150] Step 420: Determine a target power loss assessment result of the charging station according to the indicator values ​​corresponding to one or more power loss assessment factors.

[0151] In some embodiments, the server may calculate the power loss assessment score corresponding to the charging station to be evaluated based on the indicator values ​​corresponding to the charging station to be evaluated and one or more power loss assessment factors, and use the power loss assessment score corresponding to the charging station to be evaluated as the target power loss assessment result.

[0152] Specifically, the server can determine the maximum index value and the minimum index value corresponding to each power loss assessment factor based on the index values ​​corresponding to multiple charging stations to be evaluated and one or more power loss assessment factors; then the server can calculate the first distance corresponding to the charging station to be evaluated based on the difference between the index values ​​corresponding to the charging station to be evaluated and each power loss assessment factor and the maximum index value corresponding to each power loss assessment factor; the server can calculate the second distance corresponding to the charging station to be evaluated based on the difference between the index values ​​corresponding to the charging station to be evaluated and each power loss assessment factor and the minimum index value corresponding to each power loss assessment factor; then the server can calculate the power loss assessment score corresponding to the charging station to be evaluated based on the first distance and the second distance corresponding to the charging station to be evaluated.

[0153] For example, the index values ​​corresponding to the plurality of charging stations to be evaluated and the one or more power loss evaluation factors can be expressed as the following formula (4):

[0154]

[0155] Where n represents the total number of charging stations to be evaluated; m represents the total number of power loss evaluation factors; z nm It can represent the index value corresponding to the nth charging station and the mth power loss assessment factor.

[0156] The minimum index value corresponding to each power loss assessment factor can be expressed as:

[0157]

[0158] Among them, min{z 11 ,z 21 ,...,z n1} may represent obtaining the minimum index value among the index values ​​of the first power loss assessment index corresponding to each charging station to be assessed; min{z 12 ,z 22 ,...,z n2} may represent obtaining the minimum index value among the index values ​​of the second power loss assessment index corresponding to each charging station to be assessed; min{z 1m ,z 2m ,...,z nm} may represent obtaining the minimum index value among the index values ​​of the mth power loss assessment index corresponding to each charging station to be assessed; arrive It can respectively represent the minimum index values ​​corresponding to the 1st power loss assessment factor to the mth power loss assessment factor.

[0159] The maximum index value corresponding to each power loss assessment factor can be expressed as:

[0160]

[0161] Among them, max{z 11 ,z 21 ,...,z n1} may represent obtaining the maximum index value among the index values ​​of the first power loss assessment index corresponding to each charging station to be assessed; max{z 12 ,z 22 ,...,z n2} may represent obtaining the maximum index value among the index values ​​of the second power loss assessment index corresponding to each charging station to be assessed; max{z 1m ,z 2m ,...,z nm} may represent obtaining the maximum index value among the index values ​​of the mth power loss assessment index corresponding to each charging station to be assessed; arrive It can respectively represent the maximum index values ​​corresponding to the 1st power loss assessment factor to the mth power loss assessment factor.

[0162] Then the first distance corresponding to the i-th charging station to be evaluated can be calculated by referring to the following formula (5):

[0163]

[0164] in, may represent the first distance corresponding to the i-th charging station to be evaluated; w j It can represent the weight corresponding to the jth power loss assessment factor; It can represent the maximum index value corresponding to the jth power loss assessment factor; ij It can represent the index value corresponding to the i-th charging station to be evaluated and the j-th power loss assessment factor.

[0165] The second distance corresponding to the i-th charging station to be evaluated can be calculated by referring to the following formula (6):

[0166]

[0167] in, may represent the second distance corresponding to the i-th charging station to be evaluated; w j It can represent the weight corresponding to the jth power loss assessment factor; It can represent the minimum index value corresponding to the jth power loss assessment factor; ij It can represent the index value corresponding to the i-th charging station to be evaluated and the j-th power loss assessment factor.

[0168] Then according to the first distance corresponding to the i-th charging station to be evaluated and the second distance The calculation of the power loss assessment score corresponding to the i-th charging station to be evaluated can refer to the following formula (7):

[0169]

[0170] Among them, S i It can represent the power loss assessment score corresponding to the i-th charging station to be evaluated.

[0171] In the embodiment of the present application, the server can obtain the index values ​​corresponding to the charging site to be evaluated and one or more power loss evaluation factors, wherein the one or more power loss evaluation factors include at least one of the following: charging line length, ambient temperature, charging voltage and charging pile comprehensive performance, wherein the charging line length refers to the line length of the charging equipment at the charging site, the ambient temperature refers to the temperature of the environment in which the charging site is located, the charging voltage refers to the voltage output by the charging equipment in the charging site to be evaluated, and the charging pile comprehensive performance is used to characterize the charging efficiency of the charging equipment at the charging site; and then the server can determine the target power loss evaluation result of the charging site to be evaluated according to the index values ​​corresponding to the one or more power loss evaluation factors. By integrating multiple power loss evaluation factors such as charging line length, ambient temperature, charging voltage and charging pile comprehensive performance, the target power loss evaluation result can be made more accurate, improving the user's charging experience and satisfaction.
