There is a need of integration between fuel cell (FC) and battery to help electric vehicle to work under cold start, acceleration and deceleration modes, which are problems unique to an electric vehicle application. The dynamics of FC is slower compared with the electric vehicle load dynamics and there is a need to design suitable converters for interfacing auxiliary source during this period. The converters interfacing the auxiliary power source (battery) need to have faster dynamic response so that it can interface the battery with DC bus bar. In the fuel cell hybrid electric vehicle (FCHEV), during cold start mode, the battery supplies to the DC bus bar during the heat up process. In this article, the architecture of FCHEV has been developed using a resonant DAB-IBDC converter with symmetric CLLC. The architecture of FCHEV had analyzed and modeled in this manuscript. The model of FC accounting for material conservation, delay effects due to fuel and oxidant, and losses has also developed to get more accurate FC output voltage. The operation of the FCHEV during cold start, normal, acceleration and deceleration conditions studied in detail. Furthermore, simulation results of the designed 1.4 kW EV verify with theoretical analysis in the four modes for urban transport applications especially for three-wheeler applications like e-rickshaw.
