Application scheme of charging pile

　　 Charging pile electric vehicle as a kind of green transportation with broad development prospects , In the future, the popularization speed will be extremely fast , The future market prospect will also be great . In the context of the global energy crisis and environmental crisis , The Chinese government actively promotes the application and development of new energy vehicles . Charge / As an important supporting infrastructure necessary for the development of electric vehicles , It has very important social and economic benefits . Electric vehicle charging / The construction of replacement power stations has been carried out nationwide .
　　 The whole system consists of electric vehicle charging piles 、 Concentrator 、 The battery management system consists of four parts (BMS), Charging management service platform .

　　 Electric car charging post ( bolt ) The control circuit of is mainly embedded ARM After the processor completes , Users can swipe their cards for user identification 、 Balance inquiry 、 Charge inquiry and other functions , It can also provide voice output interface , Realize voice interaction . The user can choose four charging methods according to the instructions of the LCD ： Including charging on time 、 Charge according to the electricity 、 Automatic charging 、 Charge by mileage .
　　 Electric vehicle charger controller and concentrator use CAN Bus for data interaction , The concentrator and server platform use wired internet or wireless Internet GPRS Network data interaction , To be on the safe side , Secure encryption of electricity billing and amount data .
　　 Battery management system (BMS) The main function is to monitor the working state of the battery （ Battery voltage 、 Current and temperature ）, Predict the battery capacity of the power battery (SOC) And the corresponding remaining mileage , Battery management , Avoid over discharge 、 Overcharge 、 Overheating and serious imbalance between individual batteries , Maximize the storage capacity and cycle life of the battery .
　　 Charging service management platform mainly includes charging management 、 Charging operation 、 Comprehensive query of three functions . Basic data involved in the centralized charging management system , Such as electric vehicle information 、 Battery information 、 User card information 、 Charging pile （ Bolt ） Information ; Charging operation mainly manages user charging ; Comprehensive query refers to the comprehensive analysis and query of management and operation data .
