Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
Under the large background of energy conservation and emission reduction of automobiles, the technology of the electric automobiles is rapidly developed, and from the perspective of user experience, the charging time of the automobiles is effectively reduced, so that the products have higher market competitiveness. The current direct current common mode of charging is that the single stake charges to in the daily life scene, for example the charging area such as market, it all is single existence to fill electric pile, however, is subject to the restraint of electric framework, and the single stake can't provide the electric current that is greater than 250A for the vehicle, and the charging time of difficult effective reduction vehicle influences user and uses experience.
Based on the above problem, an embodiment of the present invention provides a multi-charging-pile combined charging method, as shown in fig. 1, the multi-charging-pile combined charging method specifically includes the following steps:
step S101: and acquiring the current use state of each charging pile in the target area and the combined charging requirement of the object to be charged.
The target area can be areas where a plurality of charging piles are distributed, such as shopping malls and office buildings, the current use state of each charging pile is divided into charging and idle states, the combined charging demand is that after an object to be charged, namely an electric automobile, is connected into a certain charging pile, a charging mode selected and set by a user on the charging pile is a multi-pile combined charging mode. This joint charging demand specifically includes: the charging time, the charging current and other parameters required by the electric automobile.
Step S102: and determining a target charging pile based on the combined charging demand.
Specifically, in an embodiment, the step S102 specifically includes the following steps:
step S201: and determining the target charging pile identifier of the current connection of the object to be charged based on the combined charging requirement.
Step S202: and determining the target charging pile based on the target charging pile identifier.
Specifically, each charging pile in the target area has a unique identifier, and if all charging piles in the target area are uniformly numbered, the number corresponding to each charging pile is the charging pile identifier corresponding to the charging pile. When a user provides a combined charging demand through a certain charging pile, the combined charging demand can be provided with the serial number of the charging pile, so that the charging pile which is actually plugged and connected with an electric automobile of the user can be determined by identifying the charging pile identification on the combined charging demand, and the charging pile is the target charging pile.
Step S103: and determining a first charging pile set participating in the joint charging based on the joint charging demand and the current use state of each charging pile.
Specifically, because the use states of the charging piles are different, some charging piles may be currently providing charging services for other users, and such charging piles cannot participate in combined charging, so that the charging pile preparation work of multi-pile combined charging can be realized by screening the charging piles to obtain a charging pile set for charging each auxiliary main charging pile meeting the combined charging requirement.
Step S104: and establishing a charging relation between the target charging pile and the object to be charged.
Specifically, a charging relation between the target charging pile and the object to be charged is established based on the target charging pile identifier. Illustratively, the BMS of the electric vehicle can communicate with the charging post through the number of the target charging post, so that the BMS can complete the preparation and configuration of the charging and the control of the charging process according to the actual situation.
Step S105: and controlling the target charging pile and the first charging pile to be integrated into an object to be charged for joint charging based on the charging relation and the joint charging requirement.
Specifically, all the power supply lines of the charging piles in the target area are connected in parallel, so that each charging pile can independently provide single-pile charging for a user, and multi-pile combined charging can be realized through the mutually connected power supply lines.
By executing the steps, the multi-charging-pile combined charging method provided by the embodiment of the invention automatically matches a plurality of charging piles for combined charging based on the combined charging requirement of the user and the use state of the charging piles in the target area, so that the combined large-current rapid charging of the multi-charging-pile is realized, the single charging time of the user is shortened by reasonably utilizing the limited charging pile resources, the charging efficiency is improved, and the use experience of the user is further improved.
Specifically, in an embodiment, the step S103 specifically includes the following steps:
step S301: a target charging current for the object to be charged is determined based on the combined charging demand.
Specifically, the target charging current is updated based on the first charging current by acquiring the first charging current corresponding to the target charging pile. For example, assuming that the charging current required in the combined charging requirement set by the user is 1000A, and assuming that the charging current provided by the target charging post is 250A, the required target charging current is 750A.
Step S302: and selecting a first charging pile set meeting the target charging current requirement from the charging piles of which the current use state is the idle state.
Specifically, in step S302, the number of charging piles participating in the combined charging is determined based on the target charging current and the preset single-pile charging current; charging piles meeting the number of the charging piles are selected from the charging piles in the idle state in the current use state to form a first charging pile set. For example, assuming that the target charging current is 750A and the preset single-pile charging current is 250A, a total of 3 charging piles are required to participate in joint charging in addition to the target charging pile, and then five charging piles are selected from all the idle charging piles to form a first charging pile set.
In practical application, the first charging pile set may be screened according to factors such as the current remaining power condition of each charging pile, so as to further improve the charging effect of the combined charging.
Specifically, in an embodiment, the step S105 specifically includes the following steps:
step S401: and acquiring a first charging pile identifier corresponding to each first charging pile in the first charging pile set.
Wherein, the first electric pile sign that fills is the number that each electric pile that fills who participates in joint charging corresponds.
Step S402: first data of the object to be charged, which are generated to the target charging pile based on the charging relation, are received, and the first data are forwarded to each first charging pile based on the first charging pile identification.
Specifically, after a certain charging pile is connected to a gun, the electric vehicle can perform communication in the whole charging process to the charging pile through a Battery Management System (BMS System) of the electric vehicle, such as: the charging pile parameter configuration, the monitoring of the charging state in the charging process and the like are realized, and because other charging piles participate in charging, the data messages sent by the BMS and received by the target charging pile are forwarded to the charging piles participating in the combined charging according to the charging pile identifications corresponding to the charging piles for responding.
Step S403: and receiving second data sent by each first charging pile, and forwarding the second data to the target charging pile so that the target charging pile feeds the second data back to the object to be charged based on the charging relation.
Specifically, after all the charging piles participating in the combined charging are executed according to parameter configuration requirements or state monitoring requirements sent by the BMS, the obtained execution data is finally fed back to the BMS through the target charging pile, so that data communication between the BMS and all the charging piles participating in the combined charging is realized, and multi-pile combined charging for the same electric vehicle can be realized based on data messages in the whole charging process.
It should be noted that, the format and content of the communication message related to the BMS and the charging pile in the whole charging process and the specific implementation process of each charging pile for performing parameter configuration and monitoring of the charging process according to the communication message are the prior art, and specific reference may be made to the related description of the prior art, which is not described herein again.
By executing the steps, the multi-charging-pile combined charging method provided by the embodiment of the invention automatically matches a plurality of charging piles for combined charging based on the combined charging requirement of the user and the use state of the charging piles in the target area, so that the combined large-current rapid charging of the multi-charging-pile is realized, the single charging time of the user is shortened by reasonably utilizing the limited charging pile resources, the charging efficiency is improved, and the use experience of the user is further improved.
