Intelligent charging pile of electric vehicles

Abstract

The invention provides an intelligent charging pile of electric vehicles, and belongs to the technical field of charging equipment. The charging pile comprises an AC / DC power supply module, an electric parameter acquisition module, an electric quantity measurement module and a main control MCU, wherein the AC / DC power supply module, the electric parameter acquisition module, the electric quantitymeasurement module and the main control MCU are sequentially connected, the AC / DC power supply module is connected with commercial power, the main control MCU is connected with an IC card reading module, a coin-feed module and a communication module. The electric parameter acquisition module is connected with the load control module, the temperature acquisition module and the leakage protection module, the main control MCU is connected with the temperature acquisition module, the load control module is connected with the charging output module, the electric quantity measurement module accurately acquires the voltage, the current, the power, the power factor and the electric energy consumption in the charging process in real time. The charging data acquisition part of the intelligent charging pile of electric vehicles adopts the electric quantity metering chip to accurately acquire the voltage, the current, the power, the power factor and the electric energy consumption in the chargingprocess in real time, and charges according to the actual consumed electric quantity.

Description

technical field [0001] The invention belongs to the technical field of charging equipment, and in particular relates to an electric vehicle intelligent charging pile. Background technique [0002] At present, the number of electric vehicles in China is 180 million. According to incomplete statistics, there are tens of thousands of fires in the country every year, causing heavy casualties and property losses. The main cause of fires is the irregular charging of electric vehicles. If there is no corresponding parking and charging area for electric bicycles, the phenomenon of privately pulling random connections or moving batteries upstairs for charging often occurs. If a phenomenon such as a fire caused by charging occurs, it may bring great property losses, after all, the scope of the impact is relatively concentrated. [0003] In addition, due to the lack of safe charging equipment in the community, the owners have the phenomenon of pulling wires and charging in front of th...
