More intelligent electric pile that fills can connect at the car and fill electric pile back, carries out remote control on the cell-phone, regularly charges, and the peak of charging is stagger, sparingly charges the expense.
The development of the V2G technology, V2G is short for Vehicle-to-Grid, and the core idea is to utilize a large amount of energy storage resources of electric vehicles as the buffer of a power Grid and renewable energy sources to realize bidirectional communication and bidirectional energy flow between the electric vehicles and the power Grid. The charging and discharging process of the electric automobile can be efficiently managed, the load generated when the electric automobile is charged and the impact on a power grid are reduced to the minimum, and meanwhile, the power resources of the electric automobile are fully utilized to improve the stability and the flexibility of the power grid. When the load of the power grid is too high, the energy storage resources of the electric automobile can feed electricity to the power grid, and when the load of the power grid is low, the electric automobile can store the surplus generated energy of the power grid, so that the resource waste is reduced. Use V2G technique on filling electric pile, the promotion that can be better fills electric pile trend intellectuality, promotes to fill electric pile market trend maturity.
And (4) the environment is compatible. The charging network is an infrastructure, and charging users, non-users, parking environments and city management rules are industrial environments for industry development. It is a common need for the growth of various industries by building environmentally compatible product designs and business models. The application of innovation methods such as potential value mining, grafting innovation, environment-compatible product design and the like in the charging pile construction industry is researched, value creation is realized through innovation, and the trend of industry development is to construct a social co-creation and win-win business model.
Big data and artificial intelligence applications. By utilizing a big data technology, a data island of a plurality of charging pile operators is opened, data interconnection and intercommunication are realized, a car-giving owner can see more service conditions of charging piles at one terminal, effective scheduling of an electric vehicle is realized, resource matching of the charging piles and the electric vehicle is realized, the existing charging pile resources are mastered, the problem of difficulty in charging is solved, and optimal configuration of the resources is realized.
