This paper presents a parallel energy-sharing control strategy for the application of fuel cell hybrid vehicles (FCHVs). The hybrid source discussed consists of a fuel cells (FCs) generator and energy storage units (ESUs) which composed by the battery and ultracapacitor (UC) modules. A direct current (DC) bus is used to interface between the energy sources and the electric vehicles (EV) propuls...

The use of series architecture nowadays is mainly on hybrid buses. In comparison with series-parallel and parallel architectures, which are usually exploited medium-size cars, the allows achieving internal combustion engine higher efficiency. downside this architecture, due to a double energy conversion (i.e., mechanical converted in electrical again energy), that additional losses introduced. ...

1. Introduction There is a growing demand for power semiconductors applied to motor drive inverters for electric vehicles (EVs) and hybrid electric vehicles (HEVs). Based on the results of the development and mass production of automotive power semiconductors, which require very high reliability and functionality, Mitsubishi Electric has developed the J-Series Intelligent Power Modules (IPMs) a...

This paper focuses on Hybrid Energy Storage Systems (HESS), consisting of a combination of batteries and Electric Double Layer Capacitors (EDLC), for electric urban busses. The aim of the paper is to develop a methodology to determine the hybridization percentage that allows the electric bus to work with the highest efficiency while reducing battery aging, depending on the chosen topology, cont...
