An electric vehicle intelligent charging pile with adjustable output voltage

Abstract

The invention discloses an output-voltage-adjustable intelligent charging pile for electric vehicles. The output-voltage-adjustable intelligent charging pile comprises a main charging 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 real-time power grid load detection unit, a charging load adjustment unit and an information storage unit; the man-machine interaction interface, the communication unit, the information reading unit, the metering unit, the alternating-current contactor, the real-time power grid load detection unit, the charging load adjustment unit and the information storage unit are all connected with the main charging control unit; the real-time power grid load detection unit, the metering unit, the charging load adjustment unit and the alternating-current contactor are connected on a line between a power grid and the charging socket sequentially in series. The charging pile is safe, reliable, complete in function and more suitable for 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 at that time. If the voltage is too high or too low, it will directly Charging the battery can easily damage the performance of the battery
