Using a bidirectional DC/DC converter along with low-voltage energy storage for the high-voltage dc bus supplied by a fuel cell has become a major option for FCV (Fuel Cell Vehicles) [1]–[3]. Bidirectional power flow enables energy release during startup and hill climbing, and also the energy capture of regenerative brake. A common strategy to improve fuel efficiency in a hybrid vehicle is to downsize the peak power rating of the primary energy source for more efficient operation at part load, and then make up for the deficit using peak power assist from the energy storage system [4]. One of the challenging problem for FCV energy management is the introduction of some innovative strategy able to optimize the power flow control, leading to an intelligent mode change between Buck (i.e. conversion from an higher to a lower voltage) and Boost (i.e. conversion from a lower to an higher voltage) operations.
