Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention discloses a method for scheduling charging piles in a charging station, so as to achieve saving of charging time of an electric vehicle and prolonging of service life of the charging piles, and the method for scheduling charging piles in the charging station includes:
step S01: the charging pile in the idle state in the charging station is determined, and then the process proceeds to step S02.
Specifically, the embodiment of the invention periodically or aperiodically scans the idle state of each charging pile in the charging station, and determines the charging pile currently in the idle state. The charging pile in the idle state is a charging pile which is not occupied at present and can directly charge an electric vehicle after the electric vehicle is newly connected into the electric vehicle. For example, a charging station is not currently occupied, but is locked for some reason (e.g., a user has used the charging post within a certain time period in advance, the charging post is in a locked state within the certain time period) or is disabled (e.g., a part of the charging post needs to be disabled due to insufficient power supply of a power grid, or a charging post is temporarily disabled due to maintenance), and the charging post is not listed as a charging post in an idle state.
Step S02: and respectively calculating scores of the charging piles in the idle state in the charging station under different index items. Wherein the different index items include: the charging system comprises at least one index item influencing the charging time of the electric automobile and at least one index item influencing the service life of a charging pile. Thereafter, the process proceeds to step S03.
Specifically, one fills electric pile and can save electric automobile charging time under the index item that influences electric automobile charging time more, and then should fill electric pile score under this index item higher. Fill electric pile life can prolong more under the index item that a influence fills electric pile life, then should fill electric pile score under this index item higher.
One index item that affects the charging time of an electric vehicle may be, for example, charging pile convenience. Specifically, can set up the sequencing of different charging pile convenience according to factors such as export, entry, crossing, topography in the charging station, the sequencing leans on the front more and fills electric pile convenience better, possess higher convenience score. The formula for calculating the convenience score of the charging pile may be, for example: the charging piles are sorted according to the sequence from good to bad convenience, the serial numbers of the sorting are sequentially accumulated from 1, the score of the convenience of the charging piles C1 is (total sorting serial number-current sorting serial number of the charging piles)/total sorting serial number 100%, for example, 80 charging piles exist in the charging station in total, the convenience sorting serial number of a certain charging pile is 20, and the convenience score of the charging pile C1 is (80-20)/80 × 100% 75.
Yet another index item that affects the charging time of the electric vehicle may be, for example, the charging efficiency. Specifically, the ratio of the output power to the rated power of the charging pile is the charging efficiency of the charging pile, and if the charging efficiency score C3 of the charging pile is 100% of the output power of the charging pile/the rated power of the charging pile, for example, if the rated power of a certain charging pile is 120KW and the actual output power is 105KW, the charging efficiency score C3 of the charging pile is 105/120 100% and 87.5.
In the embodiment of the present invention, the at least one index item affecting the charging time of the electric vehicle may be set to include: any one or two of the two index items of the convenience and the charging efficiency of the charging pile are provided.
One index item influencing the service life of the charging pile can be, for example, the use frequency of the charging pile or the total use duration of the charging pile. Specifically, the use frequencies of different charging piles in the same charging station may be different, and the more frequently a charging pile is used, the faster the life loss of electronic components in the charging pile is, so that the service life of the charging pile is shortened, and therefore the use frequency of the charging pile is used as an index item influencing the service life of the charging pile in the embodiment of the invention. Generally speaking, a fill electric pile and use more frequently, should fill electric pile and use total duration just longer, so can use total duration to replace filling electric pile frequency of use as the index item that influences electric pile life with filling electric pile. The formula for calculating the total duration of use of the charging pile may be, for example: the total charging pile usage duration score C2 is (average of total usage duration of all charging piles-total usage duration of current charging piles)/average of total usage duration of all charging piles 100%, for example, there are 80 charging piles in total in the charging station, the sum of total usage duration of all charging piles in the charging station is 30000 hours, the total usage duration of a certain charging pile is 200 hours, and then the total usage duration score C2 of the charging pile is (30000/80-200)/30000/80 is 100% — 46.7.
Step S03: and calculating the scores of each charging pile in the idle state in the charging station according to different index items, and performing weighting and summarizing to obtain a comprehensive score. Thereafter, the process proceeds to step S04.
Specifically, the weights of different index items can be set according to actual needs. For example, considering that a user side and an operator are both benefited by the method for dispatching the charging piles in the charging station, the service life of the charging piles is adjusted to be beneficial to the operator, the charging time of the electric vehicle can bring convenience and rapidness to customers, the factors beneficial to both sides can be set to account for 50%, and then the weight of the use frequency of the charging piles can be set to be 50% under the condition that the considered index items are the convenience of the charging piles, the charging efficiency and the use frequency of the charging piles. The charging pile convenience and the charging efficiency are weighted together to account for 50%, and considering that the charging efficiency is more influenced by the charging pile convenience to users than the charging pile convenience, the weight of the assignable charging efficiency is 30%, and the weight of the charging pile convenience is 20%, at this time, the total score C of the charging piles after the scores under the three indexes are weighted and summarized is C1 + 20% + C2 + 50% + C3.
Step S04: and pushing the charging pile information with the highest comprehensive score to the charging user.
Specifically, the higher the composite score is, the higher the priority is. The embodiment of the invention pushes the charging pile composite message with the highest priority to the charging user, and guides the user to go to the charging pile with the high priority for charging, so as to realize the win-win situation of the user and the operator to the maximum extent.
The pushing mode may be any one of the following two modes:
1) the charging pile information with the highest comprehensive score is displayed on a display screen of a charging station entrance, and the message content can be as follows: the honored user advises you to charge the charging pile No. 3 according to the intelligent operation result of the station.
2) Sending the charging pile information with the highest comprehensive score to a portable intelligent terminal of a user; the mode of sending to the portable intelligent terminal of the user includes but is not limited to a mobile APP, an applet, a public number and the like, and the portable intelligent terminal includes but is not limited to a smart phone or a smart watch and the like. The user can enter a mobile APP, an applet or a public number by scanning a two-dimensional code shown at the entrance of the substation to receive the push information.
As can be seen from the above description of the embodiments of the present invention, the embodiments of the present invention comprehensively consider factors such as the charging time of the electric vehicle and the service life of the charging pile to calculate the comprehensive score of each charging pile in the idle state in the charging station, determine the charging pile information with the highest comprehensive score to recommend to the user, and guide the user to go to the charging pile with the highest priority for charging, thereby achieving saving of the charging time of the electric vehicle and prolonging of the service life of the charging pile.
In addition, when the power supply of the charging station power grid is insufficient, if all the charging piles are charged, the actual output power of each charging pile is lower than the rated power, and the charging time of a user is prolonged. Therefore, after the charging pile information with the highest comprehensive score is pushed to the user each time, the embodiment of the invention can further comprise: when the input total power of the charging station is less than the sum of the rated power of all charging piles, the charging pile with the lowest priority is closed to ensure that other charging piles can operate at full power, and the charging time of a single user is reduced by changing the time in space.
As shown in fig. 2, the corresponding method for scheduling charging piles in charging stations includes:
step S11: the charging pile in the idle state in the charging station is determined, and then the process proceeds to step S12.
Step S12: respectively calculating scores of each charging pile in an idle state in the charging station under different index items; the different index items comprise at least one index item influencing the charging time of the electric automobile and at least one index item influencing the service life of the charging pile. Thereafter, the process proceeds to step S13.
Step S13: and calculating the scores of each charging pile in the idle state in the charging station according to different index items, and performing weighting and summarizing to obtain a comprehensive score. Thereafter, the process proceeds to step S14.
Step S14: and pushing the charging pile information with the highest comprehensive score to the charging user. Thereafter, the process proceeds to step S15.
Step S15: and judging whether the total input power of the charging station is less than the sum of the rated powers of all the charging piles, if so, entering the step S16, otherwise, returning to the step S11.
Step S16: and closing the charging pile with the lowest comprehensive score, and then, entering the step S15.
