Adaptive energy management for hybrid power system considering fuel economy and battery longevity

• Energy management method of electric vehicles with triple-source hybrid powertrain. Vehicle fuel economy and battery longevity are optimized at the same time. An adaptive constraint update algorithm is proposed for power distribution issue. A HIL platform used to experimentally validate presented EMS. It proved that total PHEV can be improved by approach. The adoption powertrain technology brings a bright prospective improve environmental friendliness traditional oil-fueled automotive solve range anxiety problem vehicle. However, concern aging cost main reason keeps plug-in (PHEV) from being popular. To PHEV, this paper proposes win-win energy strategy (EMS) Engine-Battery-Supercapacitor powertrains reduce consumption degradation First all, novel hierarchical optimization framework developed, where internal combustion engine (ICE), super capacitor (SC) gradationally scheduled. Then, an updating rule developed vehicle efficiency mitigate costs. Additionally, control-oriented analyzing model established evaluate PHEV. quantified operation further designed as feedback signal performance algorithm. verified Hardware-in-the-loop experiment. results indicate EMS coordinates ICE, driving motor (DM) storage system effectively reduced 6.1% 28.6% respectively compared Overall, introduction SC effectively. justify effectiveness economic conventional ones, which will encourage promotion PHEVs.
