Description
Technical Field

Background
The charging pile in the technology is public quick charging equipment. At present, the conventional fuel oil automobile is refueled for only a few minutes, and the electric automobile is quickly charged for only a few tens of minutes or even a few hours. Even though the construction of charging pile (station) infrastructure has been advanced vigorously in recent years, the situation of queuing a large amount of charging piles is frequent, especially during the peak period of charging. Although each type of charging arrangement has its own corresponding APP, it can observe the free charging piles of nearby or pre-arrived charging stations and the situation where charging piles are in use. But when the owner reaches the charging stake, other owners may be placed in front of it.
For example, "patent publication No.: CN117291757a, name: a charging pile dispatching system and a charging pile dispatching method' are disclosed in Chinese patent, which comprises: the mobile terminal is used for sending request information to the charging scheduling cloud platform; the charging scheduling cloud platform is used for updating charging pile time period information based on the request information and the vehicle information pre-bound by the mobile terminal and synchronizing the charging pile time period information to the charging pile management system, wherein the charging pile time period information comprises time period types and corresponding time period vehicle information; the charging pile management system is used for acquiring target vehicle information corresponding to the vehicle end system and controlling the opening or closing of charging permission corresponding to the target charging pile according to the target vehicle information and the charging pile period information. This technique simply reserves charging to occupy the charging pile in advance, but cannot be dynamically evaluated for a charging pile that is about to end in the reservation time to the charging start time. And other autonomous interrupt charges cannot be updated before the start of the charging time. The technology can only reserve the reserved charging piles at reserved time, and the scheduling efficiency is still low. For example, if other vehicles start charging before the reserved charging starts and still in a charging state at the start of the reserved charging, the conflict between the reserved charging and the occupation of the other people in charging cannot be resolved.
And the patent publication number is as follows: CN110322120a, name: the invention relates to a Chinese patent invention of an electric vehicle charging scheduling method and system based on benefit maximization, which comprises the following steps: acquiring a charging station position recommended for a user according to the collected road condition information, the current vehicle information, the information of the nearby charging stations and the benefit maximization principle; obtaining the recommended charging electric quantity for the user according to the historical driving information of the vehicle and the benefit maximization principle; and charging according to the charging station position and the charging quantity. The technology only stands at the angle of the charging pile to maximize benefits, but congestion and queuing charging still exists for the electric automobile owners, and the technology is not unmanned charging, but is required to solve the problem of charging congestion and queuing.
Therefore, it is urgently needed to provide a charging pile reservation charging scheduling method and device based on block chain, which is simple in logic, safe and reliable.
