Energy Optimization of Electric Vehicles by Distributing Driving Power Considering System State Changes

In a battery-electric vehicle, representative electric there is growing demand for performance and one-charge mileage improvement. As an alternative to such improvements, the capacity of battery has been increased; however, due corresponding increase in weight limited space increasing also limitations. Therefore, researches are being actively conducted improve system operation efficiency overcome This paper proposes distributing method driving forces battery-powered shuttle bus last-mile mobility equipped with decentralized while taking into account voltage changes input terminals charge. The were compared evaluated by performing energy consumption analysis using ‘Manhattan Bus Driving Cycle’ at low condition (SOC 20%). Various analyzes performed compared, as uniform distribution front rear wheels (Uniform), optimization without considering terminal change (Vnorm = 90 V), (Vdclink). result, it shows that proposed algorithm can 6.0% conventional force (Uniform). Moreover, real-time V) 5.3% method. obtain additional 0.7% total cost existing method, which vehicle cost-effectiveness reducing required achieve same mileage.
