This paper presents a Matlab/Simulink toolbox for the backward quasi-static modelling and simulation of Hybrid and Electrical Power-trains (HEP) mainly direct towards their correct sizing and optimization. The tool consists of several blocks representing the main components of a power-train, e.g. thermal engines, electrical motors and generators, electrical storage devices, clutches, transmissions and other mechanical coupling equipment, all of them characterized by their static efficiency maps. Mission profiles, fuel consumption and emission indexes, control and management logics are also included. The framework is also equipped with GUI interfaces and graphics functions for helping out-of-range exceptions handling and parameter/result import/export functions towards Excel files for further analyses and final presentations. The final goal of the toolbox is that of providing a friendly virtual framework for the initial sizing of HEP which allows the designer to quickly build, simulate and verify the effectiveness of a power-train with respect to given objectives on efficiency, fuel consumption and emissions reduction along a given mission profile. A case of study undertaken with the present toolbox is presented in order to demonstrate its effectiveness.
