A smart charging pile for electric vehicles

Abstract

The invention discloses an intelligent charging pile of an electrombile, which comprises a charging main control unit, a human-computer interaction interface, a communication unit, an information reading unit, a measurement unit, an alternating current contactor and a charging socket, wherein the intelligent charging pile further comprises a real-time load detection unit of a power grid, a charging load regulating unit, a coin recognition unit and an information storage unit; the human-computer interaction interface, the communication unit, the information reading unit, the measurement unit, the alternating current contactor, the real-time load detection unit of the power grid, the charging load regulating unit, the coin recognition unit and the information storage unit are connected with the charging main control unit respectively; the real-time load detection unit of the power grid, the measurement unit, the charging load regulating unit and the alternating current contactor are sequentially connected in series onto a circuit between the power grid and the charging socket. The intelligent charging pile of the electrombile is safe and reliable, comprehensive in functions, and more suitable for being used by the masses.

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 ...

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".
