| Abstract | |
This paper proposes an energy management system (EMS) applied to a series hybrid vehicle (SHV) powered by an internal combustion engine (ICE) and a hybrid energy storage system (HESS) consisting of chemical batteries and supercapacitors. The EMS enables power sharing among the ICE and the HESS under a fully active topology to improve control flexibility, considering that the ICE-generator set and HESS efficiencies are limited to a specific power injection operating range and transient responses. In this context, power sharing is performed using S-shaped functions that focus on maximizing supercapacitor usability to reduce fuel consumption and battery current stress. The advantage of the S-shaped function lies on its easy configuration and reduced number of control parameters. Additionally, meta-heuristic optimization is used to tune the S-shaped functions according to the sources requirements for optimal performance in standard driving cycles, while Lyapunov's indirect method performs the stability analysis of the control strategy. Finally, experimental and computational simulations are accomplished to evaluate the effectiveness of the proposed EMS compared with traditional methods and an optimal approach. (AU) | |
