Charging device

Abstract

The invention discloses a charging device which comprises a master control charging unit, a man-machine interaction interface, a communication unit, an information reading unit, a metering unit, an alternating current contactor and a charging socket. An intelligent charging pile further comprises a power grid real-time load detection unit, a charging load adjusting unit, a battery information detection unit, a money recognition unit and an information storage unit. The master control charging unit comprises an information processing center module, a communication module, a user request information receiving module, an instruction output module, a metering information receiving module, a power grid information receiving module and a battery information receiving module, wherein the communication module, the user request information receiving module, the instruction output module, the metering information receiving module, the power grid information receiving module and the battery information receiving module are connected with the information processing center module respectively. The power grid real-time load detection unit, the metering unit, the charging load adjusting unit and the alternating current contactor are sequentially connected on a circuit between a power grid and a charging socket in series. The charging pile is safe and reliable, comprehensive in functions and more suitable for using of the mass.

Description

technical field [0001] The invention relates to a charging device, in particular to a charging device for an electric vehicle. 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 three t...

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, and only supports card swiping Charging mode, that is, pre-payment and then consumption mode, for users who do not have a card or do not recharge in time, they can only "look and sigh".
