At present, the development of electric automobiles can accelerate fuel oil substitution and reduce the carbon emission of automobile exhaust, and has important significance for guaranteeing energy safety, promoting energy conservation and emission reduction, preventing and treating atmospheric pollution and promoting China to move from the automobile kingdom to the automobile strong country. With the continuous acceleration of the development of the electric automobile industry, the quantity of electric automobiles in China is higher and higher, and as one of the most important charging infrastructures of the electric automobiles, the charging facility is important to provide charging service for users safely, reliably, conveniently and effectively.
Before 2020, in the popularization and application process of the pure electric vehicle, due to the factors of insufficient battery endurance mileage, few charging infrastructures, poor electric vehicle security value and the like, private car owners purchase and use a few of the pure electric vehicle, and the pure electric vehicle is mainly applied to the field of public transportation, such as buses, taxis, network appointment vehicles, logistics vehicles, official commuters and the like. However, with the improvement of charging facilities, the vigorous popularization of national policies, the continuous innovation of battery technology, the increase of endurance mileage, the promotion of various factors such as the construction of factories in Tesla, and the like, the improvement of the manufacturing level and the quality of electric vehicles is promoted, the electric vehicles are gradually accepted by common people, users who buy and use electric vehicles rapidly increase, Tesla is difficult to obtain, the BYD sales volume is doubled, and the household trend of pure electric vehicles is gradually formed.
The problem of charging is still popularized to present puzzlement domestic electric automobile, looks for a difficulty, and public charging station is not many and unstable, has the stake to fill, and the charge expense is expensive (need to pay service fee + charges of electricity), and the charge time is still longer etc. with refueling time comparing. Therefore, the household car owner wants to install the charging pile in the residential area and the parking space, so that the charging pile can be charged as long as the household car owner returns home, waiting time is shortened, and cost is low. However, in all old districts, especially in main urban areas of various cities, the construction period is long, the charging capacity is not reserved in the original power supply and distribution facilities, the capacity exceeds the power consumption of two families by 7KW of a slow charging alternating current pile, and the expansion cost of the electric power of the old districts is high and the difficulty is high, so that the contradiction between the urgent pile construction demand of private electric vehicle users and the serious shortage of the electric power capacity is caused.
Through the above analysis, the problems and defects of the prior art are as follows: the number of the existing electric automobile charging stations is insufficient, operators are numerous, corresponding APPs need to be downloaded by an automobile owner aiming at different operators, and information management and charging pricing are disordered; the private charging pile is difficult to install and use due to serious shortage of power capacity of a community, a power supply transformer is in a full-load or even overload state in a charging peak period, ordered charging cannot be realized, safety accidents are easy to cause, and no electric equipment exists when the power supply capacity is sufficient in a late night period, so that the power resource is not sufficiently utilized; the existing charging pile self-built by a private electric vehicle owner does not have an intelligent information system, and the external sharing of vacant time periods is difficult to realize; residential property can not provide charging service and effective management for the electric vehicle, so that residential experience is improved, and contradiction between the residential property and an owner is caused.
The difficulty in solving the above problems and defects is: the existing power supply capacity of residential communities is seriously insufficient, or the power consumption of the residential communities is very unbalanced, the expansion method is high in cost and uneconomical, and the technical and construction difficulty of the residential communities is high.
The significance of solving the problems and the defects is as follows: through the real-time supervision to transformer power supply capacity, can be under the current power supply facility equipment condition of unchanging the district, solve the district owner and build the demand of filling electric pile by oneself, can also supply power to the electric wire netting and cut off the peak and fill the valley, guarantee the electric wire netting steady operation, the electric motor car owner can also share the electric pile and the parking stall of oneself and increase the income, intelligent orderly charging still avoids the contradiction between the owner, between owner and the property, is a win-win scheme of solving current old district electric automobile problem of charging.
