Design of Electric Vehicle Centralized Charging Control System Based on PLC
In order to solve the problems of energy shortage and environmental pollution caused by exhaust emissions from traditional fuel vehicles,and to achieve the goals of energy conservation,emission reduction,reduction of vehicle costs and environmental protection,a kind of mobility tool,electric vehicles,is gradually replacing fuel vehicles under the subsidies of policies.However,now the imperfection and insufficient number of charging infrastructures constrains its healthy development and comprehensive popularization.Therefore,it is especially necessary to design a charging control system.This design takes Siemens S7-200 as the control core,and through the input module,it realizes timed charging and code-sweeping charging,and has the functions of fault alarm and automatic disconnection of faulty charging piles.
