Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Before describing the embodiments of the present invention, a block chain network system for performing the block chain-based charging control method, apparatus, electronic device and medium according to the embodiments of the present invention will be described. The nodes participating in the block chain network system of the embodiment of the present invention include: the system comprises a common calculation storage node, an owner equipment node and a charging station equipment node. The common computing storage node is typically a node device in a blockchain network, and may be, for example, a city management committee power grid that guides an electric power company, store blockchain data, and participate in a blockchain transaction request interaction process. The owner device node may be a mobile terminal of a user who charges a vehicle, or a terminal device configured on the vehicle of the user, where the mobile terminal device may be a mobile phone, a tablet computer, a vehicle-mounted terminal installed on the vehicle, or the like. The charging station device node may be an overall control device node of the charging station, or may be a device node of each charging device (e.g., charging pile) that provides charging for the vehicle.
It should be noted that, in the blockchain system provided in the embodiment of the present invention, the owner device node and the charging station device node may be blockchain nodes or may not be blockchain nodes, but may interact with the blockchain nodes through an interface provided by the blockchain nodes to participate in the blockchain network. Optionally, the owner device node may be a lightweight node deployed in the owner mobile device, and the charging device node may be a lightweight node deployed in the charging device (for example, a lightweight node communication Software Development Kit (SDK) is installed on the owner mobile device and the charging device), where the lightweight node is similar to a full node, and deploys deployment data with a block chain, such as an intelligent contract, a consensus mechanism, and the like. Therefore, can participate in the transaction request interaction process of the block chain, but not store all block data. When the lightweight node needs to inquire the transaction data in the block chain, the transaction data can be acquired from other nodes in real time and verified in a set mode. The lightweight node has lower requirements on the hardware configuration of the deployed equipment, can be integrated on the operating system level, controls the hardware in the terminal equipment, can interact with the upper application software, and provides block chain support for the functions of the application software.
Fig. 1 is a flowchart illustrating a charging control method based on a blockchain executed by a node in a blockchain network according to an embodiment of the present disclosure. The present embodiment is applicable to the case of balancing the charging station loads for each area. Typically, the present embodiment may be applied to adjust the charging service fee of the charging station according to the power load information of the charging station, so as to achieve the situation of balancing the charging station loads in each area. The charging control method based on the blockchain disclosed in this embodiment may be executed by an electronic device that carries nodes in the blockchain network, and specifically may be executed by a charging control apparatus based on the blockchain, where the apparatus may be implemented by software and/or hardware and configured in the electronic device. Referring to fig. 1, the charging control method based on a blockchain executed by a node in a blockchain network according to the present embodiment includes:
and S110, acquiring the power load information of at least two charging stations from at least two charging station devices.
The power load information may include a power load value, and the power load value may be a charging power and/or a charging amount. The at least two charging stations may be charging stations located in one area, or may be charging stations located in different areas. The charging station equipment may be a charging pile.
For example, since the charging stations selected by the owner device to use the charging are unevenly distributed, the power load of the charging stations in some areas is large, and the power load of the charging stations in other areas is small, even if the charging stations are not used for charging, it is necessary to control the charging use conditions of the charging stations in each area to balance the loads of the charging stations. In the embodiment of the application, at least two charging stations acquire power load information through at least two charging piles, and report the power load information to the blockchain network, and a node in the blockchain network acquires the power load information reported by the at least two charging stations and stores the power load information in the blockchain. For example, after the power load information is acquired, at least two charging piles may generate an uplink transaction request including the power load information, and send the uplink transaction request to the blockchain network. After receiving the uplink transaction request, the blockchain node processes the received uplink transaction request, acquires the power load information of at least two charging stations, and stores the power load information in the blockchain.
In order to prevent the electric load information from being tampered, when the electric load information is reported by at least two charging stations, the electric load information can be encrypted, and then the encrypted electric load information is reported to the block chain network. After receiving the power load information, the nodes in the block chain network firstly adopt an algorithm corresponding to the time when the power load information is encrypted by at least two charging stations to decrypt the received power load information, and then store the decrypted power load information. The specific encryption method and encryption algorithm are not particularly limited.
Optionally, in this embodiment of the application, at least two charging stations may also report at least one of the identification information, the operating state information, and the location information of the charging station to the blockchain network, so that the blockchain network stores the power load information in association with at least one of the charging station identification information, the operating state information, and the location information, thereby facilitating the blockchain to determine at least one of the identification information, the operating state information, and the location information of the charging station corresponding to the power load information.
And S120, calling a first intelligent contract, determining the charging service fees of the at least two charging stations according to the power load information of the at least two charging stations, and charging the charge to the charging vehicle owner according to the charging service fees.
Wherein the first intelligent contract may include a predetermined regulation rule of the charging service fee. Because the owner generally selects a nearby charging station to charge the owner device in consideration of the location information of the owner device and the location information of the charging station, there may be many owner devices that need to be charged in some areas, and the charging stations in the areas are all used, which results in a large charging load and a large charging power and a large charging amount of the charging stations. And less owner equipment needs to be charged in a part of the area, and the charging station in the area cannot be fully utilized. Therefore, in the embodiment of the present application, the first intelligent contract may be invoked, and charging service fees of the at least two charging stations are determined according to the power load information of the at least two charging stations, so that the at least two charging stations can charge the charging vehicle owner according to their respective charging services. The charging service fee of the charging station corresponding to the power load information may be adjusted according to the power load information, and the charging service fee of another charging station may be adjusted according to the power load information. Since the charging station may be selected by the charging station owner with reference to the charging service fees of the respective charging stations while considering the owner device location information and the charging station location information, determining the charging service fees of at least two charging stations enables the number of charging loads of the charging stations to be adjusted to achieve load balancing.
In the embodiment of the present application, the charging service fee of the charging station may be positively correlated with the power load value in the power load information of the charging station. For example, for a charging station with a higher power load, there are more owner devices to be charged by using the charging station, and if it is desired to reduce the number of owner devices to be charged by selecting the charging station, the charging service fee of the charging station is adaptively increased, so that a part of the owners of the charging stations consider that the charging service fee is higher, and select a charging station with a lower charging service fee instead to charge. For the charging station with lower electric load, the charging service fee of the high charging station is adaptively reduced, so that part of vehicle owners can select the charging station to charge the vehicle owner equipment in consideration of the lower charging service fee of the charging station, and therefore the load balance adjustment of the charging station is realized.
According to the technical scheme, the charging service fees of the at least two charging stations are determined according to the electric power load information acquired from the at least two charging stations, so that the problems that partial charging stations are too large in load and the charging stations in other areas are not reasonably used due to the fact that the owner equipment is intensively charged by using the charging stations in the nearby areas are solved, and the charging service fees are dynamically adjusted according to the service conditions of the charging stations in the areas so as to balance the loads of the charging stations in the areas.
Fig. 2 is a flowchart illustrating another charging control method performed by a node in a blockchain network according to an embodiment of the present disclosure. The present embodiment is an alternative proposed on the basis of the above-described embodiments. Referring to fig. 2, the charging control method based on the block chain provided in this embodiment includes:
and S210, acquiring the power load information of at least two charging stations from at least two charging station devices.
S220, calling a first intelligent contract, determining the charging service fees of the at least two charging stations according to the power load information of the at least two charging stations, and charging the charge to a charging vehicle owner according to the charging service fees.
And S230, responding to the charging information inquiry request of the vehicle owner equipment, and sending the charging service fees of the at least two charging stations to the vehicle owner equipment so that the vehicle owner can select the charging stations to charge according to the charging service fees.
As shown in fig. 3, an APP or an applet may be loaded in the owner device, and the charging information query request is used to request to obtain the charging information of the charging station through the blockchain network, and may be generated by the APP or the applet. The APP or the applet sends a charging information query request to the blockchain network so as to access an intelligent contract in the blockchain network, obtain charging information of the charging station and facilitate the vehicle owner to select the charging station to charge the vehicle owner device according to the charging information. Because the charging service fees of at least two charging stations are stored in the block chain network, the nodes in the block chain network send the at least two charging service fees to the vehicle owner device, so that the vehicle owner can select a proper charging station to charge according to the charging service fee.
In an embodiment of the present application, the method further includes: and responding to a charging information query request of the vehicle owner equipment, and sending the working state information and the position information of the at least two charging stations to the vehicle owner equipment so that the vehicle owner can select the charging stations according to the charging service fee, the working state information and the position information.
For example, the operating state information may include whether the charging station is charging or not charging. When the vehicle owner selects the charging station to charge, the charging service fee of the charging station may need to be considered, and other factors need to be considered, so that the charging service fee, the working state information and the position information of at least two charging stations can be sent to the vehicle owner device by the node in the block chain network, and the vehicle owner can select a proper charging station to charge according to the information received by the vehicle owner device in many aspects. For example, the first charging station is not in charging, the charging service fee is lower, and the location of the first charging station is farther from the location of the vehicle owner device, the second charging station is not in charging, and the charging service fee is higher than the charging service fee of the first charging station, and the location of the second charging station is closer to the location of the vehicle owner device.
And S240, after the owner finishes charging by adopting any charging station, determining the actual charging amount.
For example, the actual charging amount of the charge may be reported to the blockchain network by the charging station, or the actual charging amount of the charge may be reported to the blockchain network by the vehicle owner device, and the blockchain network determines and stores the actual charging amount.
And S250, calling a second intelligent contract, and determining the charging fee according to the actual charging amount, the basic electricity price and the charging service fee of the charging station.
The second intelligent contract may store a calculation rule of the charging fee in advance. The basic electricity price can be a price determined by the government, is uniformly configured by the government, and is set by the government by calling a second intelligent contract in advance. The basic electricity price may fluctuate with the change of the peak period or the valley period of the power utilization, for example, the basic electricity price for charging at night may be lower than that for charging at day, and is not regulated and controlled by the intelligent contract of the block chain network. The nodes in the blockchain network can also send the basic electricity price while sending the charging service fee to the vehicle owner device. The charging fee may be calculated by: charge is charge amount (base electricity price + charge service fee). The vehicle owner device can access the block chain network, obtain the charging fee and pay the electric charge. Alternatively, after the charging of the owner device is finished, the power company may calculate the charging cost by accessing the second intelligent contract in the blockchain network, and issue the charging cost to the blockchain network, as shown in fig. 3.
