Two-way chargeable intelligent charging pile

Abstract

The invention discloses a two-way chargeable intelligent charging pile. The two-way chargeable intelligent charging pile comprises a charging main control unit, a human-machine interaction interface, a communication unit, an information reading unit, a measurement unit, an alternating current contactor and a charging socket; the two-way chargeable intelligent charging pile also comprises a power grid real-time load detecting unit, a charging load adjusting unit and a battery information detecting unit; the human-machine interaction interface, the communication unit, the information reading unit, the measurement unit, the alternating current contactor, the power grid real-time load detecting unit, the charging load adjusting unit and the battery information detecting unit are connected with the charging main control unit respectively; and the power grid real-time load detecting unit, the measurement unit, the charging load adjusting unit and the alternating current contactor are sequentially connected onto a circuit which is arranged between a power grid and the charging socket in series. The two-way chargeable intelligent charging pile has the advantages of being safe and reliable, comprehensive in function and suitable for usage of 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 ...

AI Technical Summary

Problems solved by technology

The above-mentioned charging piles can allow people to charge electric vehicles conveniently and quickly, but the charging control mode of this kind of AC charging piles is the same at present, and the charging cannot be selected according to the load of the local power grid or battery at that time.

Moreover, there may be unexpected events in the power grid in some places, which will cause the load of the power grid to drop suddenly, which will seriously affect the electricity consumption of nearby residents. However, through normal line maintenance, the maintenance time is longer, which brings great inconvenience to people's lives.
