Description
ILoad=ITraction+ILift
Ibattery=ILoad+IBOP−IDC/DC (1)
CC=(バッテリーアンペアアワー定格)*3600
バッテリー容量は、その後、非効率なバッテリー放電と充電を考慮して調整される。
Ibattery≧0の場合、CC(Ib)=3600*(バッテリーアンペアアワー定格)*e−(放電係数)*Ibattery(k)
Ibattery<0の場合、CC(Ib)=3600*((バッテリーアンペアアワー定格)−(充電係数)*Ibattery(k))
コンデンサCCは電流Ibattery(k)の電流源と並列に接続され、バッテリーの放電と充電をモデル化する。
IFC(k)=max{IFCmin;min{IFCmax;IFC(k)}}
