Status Review of Power Control Strategies for Fuel Cell Based Hybrid Electric Vehicles

Abstract

Fuel cell-hybrid electric vehicles (FC-HEVs) have become one of the most promising alternatives for the development of low emission and fuel efficient vehicles. A fuel cell vehicle can significantly benefit from being hybridized with an energy storage system (ESS), in terms of vehicle performance, fuel economy, and vehicle cost. A power control strategy is essentially required for FC-HEVs, in order to achieve appropriate power management and regulation among different energy sources and propulsion systems on board the vehicle. Based on this background, this paper aims at reviewing few widely proposed power control strategies developed for FC-HEVs. First, popularly proposed power system configurations for FC-HEVs will be introduced, followed by selectively reviewing and discussing a range of accepted power control strategies for FC-HEVs, from the point of view of critical vehicle performance parameters.
