电动车智能充电系统分析设计

ABSTRACTAs global warming and energy grew tense and serious air pollution,electricvehicles become a new kind of transportation has become more and more popular,with its green environmental protection,the transportation is convenient,the price islow wait for an advantage to capture each big market,every household has a basicelectric vehicles.Electric car charger as a important basis of quality electric cars isalso one of the important parameters of customers consider consumption,generalelectric car charger is shorter,charging slow,lots of vulcanization reaction,to producelarge amounts of gas.Charge imbalance,so let the life of the charger short greatly,make the vehicle's less and less,to satisfy our daily traffic demand.So,we start to lookfor an intelligent electric car chargers,according to the shortcomings of the ordinaryelectric car charger for the corresponding correction,this design USES two kinds ofchips,one kind is AT89C52,the other is a LM331,learned after the application ofsingle chip microcomputer and the C language knowledge to design a new type ofintelligent charger,using current mode control scheme,make its equalizing charge,donot affect the service life of the charger and electric vehicles.Using the innovation ofintegrated circuit to control chip with high power tube integration.Mainly usesimulation of the intelligent charger all kinds of hardware parts to complete thesystem of the input signal,the C language programming to complete the software part,in general,the design is based on C language and single chip microcomputerintelligent design.Key words:AT89C52;LM331;Single chip microcomputer;The C language Thecharger:Battery life
