Abstract

Electrified light commercial vehicles have gained increasing interest as an energy efficient means of transportation. At the same time, they are characterized by limited traveling range, necessitating careful design of batteries recharging planning and respective charging infrastructure deployment. Early available hydrogen fuel cell vehicles have the potential to overcome the range anxiety limitation, they require though an extended H2-refueling network. The scope of this work is to demonstrate a model-based evaluation of the H2-refueling strategy for a battery electric light commercial vehicle, equipped with a hydrogen fuel-cell based range extender. For this purpose, advanced vehicle modeling was combined with statistical analysis to thoroughly evaluate the studied vehicle's energy consumption, under a broad range of operating conditions and eventually define an optimal refueling strategy. The attempted analysis not only allowed for defining the refueling strategy, but also enabled to optimize the H2-tank size, which tends to highlight the interest of the followed approach.
