Electromobile charging pile control device with safety protection function

Abstract

The invention discloses an electromobile charging pile control device with a safety protection function, which comprises an electromobile charging central control unit and an electromobile charging execution unit. The electromobile charging central control unit mainly comprises a central processing unit (CPU) control unit, a storage unit, a radio frequency card reading unit, a communication unit and the like. The electromobile charging execution unit mainly comprises a general packet radio service (GPRS) communication unit, a human-machine interaction unit, a charge-discharge detection control unit and the like. The electromobile charging pile control device can achieve billing of charging of electromobiles and is convenient and simple in operation. The electromobile charging pile control device with the safety protection function can achieve functions of identification of users and ciphering and deciphering of data through the safety storage unit and improves safety of data transmission. The electromobile charging pile can adopt adaptive algorithm to calculate remaining electric quantity according to an energy characteristic curve of a storage battery and an equivalent circuit obtained through current and voltage of the storage battery during work, and accuracy is relatively higher.

Description

Technical field: [0001] The invention relates to a control device for an electric vehicle, in particular to a control device for a charging pile of an electric vehicle with a safety protection function. Background technique: [0002] With the low-carbon economy becoming the main theme of my country's economic development, electric vehicles can reduce oil consumption and reduce polluting gas emissions, and have become a vigorously developed industry in my country. The electric vehicle charging station provides energy supply for the operation of electric vehicles, which is a necessary supporting facility for the development of electric vehicles. However, the existing devices occupy a large area, consume more funds, and consume a lot of human resources. massive development. Therefore, the development of low-cost charging piles has become an inevitable trend in the development of electric vehicles. In terms of the realization of the existing electric vehicle charging pile tech...
