It has been shown that none of any energy sources which own high specific energy or high specific power, but not both, can solely fulfil all the demands of hybrid electric vehicle (HEV) in some circumstances. In this paper a battery/ultra-capacitor hybrid energy storage system (B/UC HESS) using ultracapacitors which replace primary sole Ni-MH energy source, without any changes in other parts of HEV was presented. Based on the energy flow of energy storage system and operating status of the vehicle, a nonlinear proportional factor control strategy with a goal of improving battery life was introduced. The simulation results under different urban driving cycles show that the peak charge/discharge currents are smoothed effectively, which benefits the battery lifetime improvement. The results also show that the buffering effect of ultracapacitors has optimized the charging and discharging processes of Ni-MH battery considerably.

This contribution outlines the design of electric vehicle direct-current (DC) bus control system supplied by a battery/ultracapacitor hybrid energy storage system, and its coordination with the fully electrified vehicle driveline control system. The control strategy features an upper-level DC bus voltage feedback controller and a direct load compensator for stiff tracking of variable (speed-dependent) voltage target. The inner control level, comprising dedicated battery and ultracapacitor current controllers, is commanded by an intermediate-level control scheme which dynamically distributes the upper-level current command between the ultracapacitor and the battery energy storage systems. The feedback control system is designed and analytical expressions for feedback controller parameters are obtained by using the damping optimum criterion. The proposed methodology is verified by means of simulations and experimentally for different realistic operating regimes, including electric vehicle DC bus load step change, hybrid energy storage system charging/discharging, and electric vehicle driveline subject to New European Driving Cycle (NEDC), Urban Driving Dynamometer Schedule (UDDS), New York Certification Cycle (NYCC) and California Unified Cycle (LA92), as well as for abrupt acceleration/deceleration regimes.
