1、电动汽车蓄电池的键合图法建模与仿真廖连莹, 赵兴福, 王仲范(qv,q430070)K1:按照键合图的规则, 分别建立了蓄电池等效电路的键合图模型和冷却系统的键合图模型, 然后将电系统和热系统耦合在一起, 实现了蓄电池系统的键合图模型。最后建立了蓄电池的数学模型和仿真模型, 并实现了动态仿真。1oM:键合图;蓄电池;电动汽车;热系统;建模与仿真ms|:TM912DSM:AcI|:1008-7923 (2005)01-0003-04ModellingandsimulationofstorgaebatteriesforelectricvehicleswithbondgraphLIAO Lian-y
