Hybrid electric vehicles (HEV) are those equipped with two or more energy sources, usually, a fuel tank with its associated internal combustion engine (ICE) and an electrical storage system (ESS), typically a bank of batteries. In order to efficiently operate the system it is necessary to determine the instantaneous power split between the two sources when the vehicle performs a predetermined duty cycle. In this work, this problem is posed as an optimal control problem with constraints. Specifically, it is posed as an inventory control problem and solved using dynamic programming (DP). Results obtained for the case of the HEV that is being developed in the Applied Electronics Group, National University of Río Cuarto are shown.
