An intelligent electric vehicle charging pile

Abstract

The invention discloses an intelligent electromobile charging pile which comprises a charging main control unit, a man-machine interaction interface, a communication unit, an information reading unit, a metering unit, an alternating-current contactor, a charging socket, a power grid real-time load detection unit, a charging load adjusting unit and a coin recognition unit. The man-machine interaction interface, the communication unit, the information reading unit, the metering unit, the alternating-current contactor, the charging socket, the power grid real-time load detection unit, the charging load adjusting unit and the coin recognition unit are connected with the charging main control unit respectively, and the power grid real-time load detection unit, the metering unit, the charging load adjusting unit and the alternating-current contactor are serially connected on a line between a power grid and the charging socket sequentially. The intelligent electromobile charging pile is safe, reliable, comprehensive in function and more suitable for the masses to use.

Description

technical field [0001] The invention relates to a charging pile, in particular to an intelligent charging pile for electric vehicles. Background technique [0002] With the increasingly intensified contradictions between economic development, energy supply, and environmental pollution, energy conservation and consumption reduction and reduction of dependence on fossil fuels have become urgent problems to be solved for the sustainable economic development of countries all over the world. Electric vehicles have the advantages of fuel saving, environmental protection, and high efficiency. Scientists and industrial circles all over the world generally believe that electric vehicles are an important clean transportation tool in the 21st century. Electric vehicle charging stations and charging networks are important infrastructure for the large-scale and industrialized development of electric vehicles. [0003] At present, electric vehicle charging facilities can be divided into ...

AI Technical Summary

Problems solved by technology

The above-mentioned charging piles allow people to charge electric vehicles conveniently and quickly, but at present, the charging control mode of this kind of AC charging piles is the same, and the charging cannot be selected according to the load of the local power grid at that time, and only supports the charging mode of swiping cards. That is, the prepaid and then consumed mode, for users who do not apply for a card or do not recharge in time, they can only "look and sigh".
