Detailed Description
Exemplary embodiments of the present application will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present application are included to facilitate understanding, and are to be considered merely exemplary. 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 application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Before describing embodiments of the present invention, a blockchain-based charging control method, device, electronic apparatus and medium blockchain network system for implementing the embodiments of the present invention will be described. The nodes participating in the blockchain network system of the embodiment of the invention comprise: the system comprises a common computing storage node, a vehicle owner equipment node and a charging station equipment node. The common computing storage node is typically a node device in a blockchain network, for example, a city management committee electric coal guiding an electric company, can store blockchain data, and can participate in a blockchain transaction request interaction process. The vehicle owner device node may be a mobile terminal of a user charging the vehicle, or a terminal device configured on the user's vehicle, which may be a cell phone, a tablet computer, a vehicle-mounted terminal mounted on the vehicle, etc. The charging station equipment node may be an overall control equipment node of the charging station, or may be an equipment node of each charging device (such as a charging post) that provides charging of the vehicle.
It should be noted that, in the blockchain system provided by the embodiment of the present invention, the main equipment node and the charging station equipment node may be blockchain nodes, or may not be blockchain nodes, but may interact with the blockchain nodes through interfaces provided by the blockchain nodes, and participate in the blockchain network. Alternatively, 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 (e.g., a lightweight node communication software development kit (Software Development Kit, SDK) installed on the owner mobile device and the charging device), similar to a full node, deployed with deployment data of a blockchain, such as smart contracts, consensus mechanisms, etc. Thus, the transaction request interaction process of the blockchain may be engaged, but not all of the blockdata is stored. When the lightweight node needs to inquire transaction data in the blockchain, the transaction data can be acquired from other nodes in real time and verified in a set mode. The lightweight node has low requirement on hardware configuration of equipment deployed by the lightweight node, the lightweight node can be integrated on an operating system level to control hardware in terminal equipment, and meanwhile, the lightweight node can interact with upper-layer application software to provide blockchain support for functions of the application software.
Fig. 1 is a flowchart of a blockchain-based charging control method performed by a node in a blockchain network according to an embodiment of the present application. The embodiment can be applied to the situation of balancing the load of charging stations in all areas. Typically, the present embodiment may be applied to a case where charging service fees of a charging station are adjusted according to electric load information of the charging station to achieve balancing of loads of charging stations in each area. The blockchain-based charging control method disclosed in the embodiment may be executed by an electronic device carrying a node in a blockchain network, and in particular, may be executed by a blockchain-based charging control device, which may be implemented by software and/or hardware and configured in the electronic device. Referring to fig. 1, the blockchain-based charging control method performed by a node in a blockchain network according to the present embodiment includes:
s110, acquiring electric load information of at least two charging stations from at least two charging station equipment.
Wherein the electrical load information may include an electrical load value, which 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 device may be a charging peg.
For example, since charging stations selected for charging by the vehicle owner device are unevenly distributed, charging stations in a part of areas have a large electric load, and charging stations in other areas have a small electric load, even are not charged, and thus, 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, the power load information is reported to a blockchain network, and nodes in the blockchain network acquire the power load information reported by at least two charging stations and store the power load information on a blockchain. For example, the uplink transaction request including the power load information may be generated by at least two charging piles after the power load information is acquired, and transmitted to the blockchain network. And after receiving the uplink transaction request, the blockchain node processes the received uplink transaction request, acquires power load information of at least two charging stations and stores the power load information in the blockchain.
In order to prevent the power load information from being tampered, when the at least two charging stations report the power load information, the power load information can be encrypted first, and then the encrypted power load information is reported to the blockchain 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, 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 the embodiment of the present application, at least two charging stations may report at least one of identification information, working state information and location information of the charging stations to the blockchain network, so that the blockchain network stores the electric load information in association with at least one of the identification information, the working state information and the location information of the charging stations, thereby facilitating the blockchain to determine at least one of the identification information, the working state information and the location information of the charging stations corresponding to the electric load information.
S120, invoking a first intelligent contract, determining 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 charging car owners according to the charging service fees.
Wherein, the first intelligent contract can comprise a predetermined regulation rule of charging service fees. Because the car owner considers the situation of car owner equipment position information and charging station position information, generally can select nearby charging stations to charge car owner equipment, therefore can lead to the car owner equipment that needs to charge in the partial region more, the charging stations in this region are all used, cause the charge load big, and the charge power and the charge quantity of charging stations are big. While fewer vehicle owners need to charge in a partial area, charging stations in that area are underutilized. Therefore, in the embodiment of the application, the first intelligent contract can be invoked, and the charge service charge of at least two charging stations is determined according to the power load information of at least two charging stations, so that the at least two charging stations can charge the charge car owners according to the respective charge service. The charge service fee of the charging station corresponding to the electric load information may be adjusted according to the electric load information, or the charge service fee of other charging stations may be adjusted according to the electric load information. Since the charging car owner may select the charging station with reference to the charging service fees of each charging station while considering the car owner device location information and the charging station location information, determining the charging service fees of at least two charging stations can adjust the charging load number of the charging stations to achieve load balancing.
In an 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 higher electric load, more vehicle owner devices are charged by using the charging station, and at this time, if the vehicle owner devices selecting the charging station to charge are expected to be reduced, the scheme adopted in the embodiment of the application is to adaptively increase the charging service fee of the charging station, so that part of vehicle owners consider that the charging service fee is higher and select the charging station with lower charging service fee to charge. For the charging station with lower electric load, the charging service charge of the high charging station is reduced adaptively, so that partial vehicle owners can select the charging station to charge vehicle owner equipment in consideration of the lower charging service charge of the charging station, and the balance adjustment of the load of the charging station is realized.
According to the technical scheme, the charging service fees of at least two charging stations are determined according to the electric load information acquired from the at least two charging stations, so that the problem that partial charging stations are excessively loaded and charging stations in other areas are not reasonably used due to the fact that the charging stations in the nearby areas are intensively used by vehicle owner equipment for charging is solved, and the effect of dynamically adjusting the charging service fees according to the service conditions of the charging stations in each area to balance the loads of the charging stations in each area is achieved.
Fig. 2 is a flow chart of another block chain based charge control method performed by a node in a block chain network according to an embodiment of the present application. This embodiment is an alternative to the embodiments described above. Referring to fig. 2, the charging control method based on the blockchain provided in this embodiment includes:
s210, acquiring electric load information of at least two charging stations from at least two charging station equipment.
S220, invoking a first intelligent contract, determining 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 charging car owners according to the charging service fees.
And S230, responding to a charging information inquiry request of the vehicle owner equipment, and sending 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, the APP or applet may be loaded in the vehicle owner device, and the charging information inquiry request is used to request to obtain charging information of the charging station through the blockchain network, and may be generated by the APP or applet. APP or applet sends the information inquiry request that charges to the blockchain network to the intelligent contract in the access blockchain network obtains the information that charges of charging station, and the car owner of being convenient for selects the charging station to charge car owner's equipment according to the information that charges. Because the charging service fees of at least two charging stations are stored in the blockchain network, the nodes in the blockchain network send the at least two charging service fees to the vehicle owner equipment, so that the vehicle owner can select the proper charging station for charging according to the charging service fee measurement.
In an embodiment of the present application, the method further includes: and responding to a charging information inquiry request of the vehicle owner equipment, and sending working state information and 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 charge, the working state information and the position information.
For example, the operating state information may include that the charging station is in charge and not in charge. When a vehicle owner selects a charging station to charge, not only the charging service charge of the charging station but also other factors are required to be considered, and the charging station is comprehensively and comprehensively measured and selected, so that nodes in the blockchain network can send the charging service charge, the working state information and the position information of at least two charging stations to vehicle owner equipment, and the vehicle owner can select a proper charging station to charge according to the information received by the vehicle owner equipment in multiple aspects. For example, the first charging station is not in charging, the charging service fee is lower, the position of the first charging station is far away from the position of the vehicle owner device, the second charging station is not in charging, the charging service fee is higher than the charging service fee of the first charging station, the position of the second charging station is near to the position of the vehicle owner device, and at the moment, the vehicle owner can balance and select the first charging station with lower charging service fee to charge the vehicle owner device.
S240, after the vehicle owner completes charging by adopting any charging station, determining an actual charging amount.
The charging station may report the actual charging amount of the charging to the blockchain network, or the vehicle owner device may report the actual charging amount of the charging to the blockchain network, and the blockchain network determines and stores the actual charging amount.
S250, invoking a second intelligent contract, and determining charging cost according to the actual charging amount, the basic electricity price and the charging service cost of the charging station.
Wherein, the second intelligent contract can be pre-stored with the calculation rule of the charge expense. The base price of electricity may be a government-determined price, uniformly configured by the government, and set by the government invoking the second smart contract in advance. The base price of electricity may also fluctuate with changes in peak or valley periods of electricity usage, e.g., the base price of electricity charged at night may be lower than the base price of electricity charged during the day, not under intelligent contract regulation control of the blockchain network. The nodes in the blockchain network can also send basic electricity prices while sending charging service fees to the vehicle owner equipment. The charging cost can be calculated by the following steps: charge rate=charge rate (basic electricity rate+charge service rate). The vehicle owner equipment can access the blockchain network, acquire charging fees and pay electric fees. Alternatively, after the charging of the main device of the electric power company is finished, the electric power company calculates the charging cost by accessing the second intelligent contract in the blockchain network, and issues the charging cost to the blockchain network, as shown in fig. 3. Note that, as in fig. 3, only two charging stations are illustrated, and the number of charging stations is not limited.
According to the embodiment of the application, the charging service fees of the at least two charging stations are sent to the vehicle owner equipment in response to the charging information inquiry request of the vehicle owner equipment, so that the vehicle owner can select the charging stations to charge according to the charging service fees, and the vehicle owner can select the charging stations to charge according to the charging service fees. After the vehicle owner finishes charging by adopting any charging station, determining the actual charging amount, calling a second intelligent contract, and determining the charging cost according to the actual charging amount, the basic electricity price and the charging service cost of the charging station, so that the charging cost is accurately calculated, and the vehicle owner pays the electricity fee.
