Intelligent charging pile of electric vehicles and charging control method thereof

Abstract

The invention discloses an intelligent charging pile of electric vehicles and a charging control method thereof. The intelligent charging pile comprises a charging master control unit, a human-computer 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 adjustment unit, a money recognition unit and an information storage unit. The human-computer interaction interface, the communication unit, the information reading unit, the metering unit, the alternating current contactor, the power grid real-time load detection unit, the charging load adjustment unit, the money recognition unit and the information storage unit are connected with the charging master control unit respectively. The power grid real-time load detection unit, the metering unit, the charging load adjustment unit and the alternating current contactor are sequentially connected onto a circuit between a power gird and the charging socket in series. The intelligent charging pile is safe, reliable, comprehensive in functions and suitable to be used by the masses.

Description

technical field [0001] The invention relates to a charging pile, in particular to an intelligent charging pile used by an electric vehicle and a charging control method thereof. 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 vehi...

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".
