“…It was concluded that the current (or power) dynamics have the major influence. Then the Root Mean Square (RMS) power (image of dynamic current) and absolute energy are used in this work to know how often battery pack and fuel cell are solicited [11]. Figure 33.5 shows the different needed evaluation parameters as RMS powers, absolute energy and the fuel consumption respectively.…”

The aim of this paper focuses on optimal sizing of Energy Storage System (ESS) based on Fuel cell using different battery technologies for Fuel Cell Electric Vehicles (FCEV) applications. The main objective consists to optimize ESS sizes, cost with a longer lifecycle for a Fuel Cell Electric Vehicle with 650 km driving cycle range. In this way, we study the influence of battery technologies which is considered as a secondary source on the storage system characteristics. The obtained results show that considerable gains have been achieved in terms of weight, volume and cost using Ultra High Power (UHP) technology comparatively with high power and high energy technologies. Otherwise, an experimental validation is carried out to complement the simulation results via a 1 kW test bench with Hardware In the Loop approach. As expected, UHP technology confirms its capabilities of decreasing the applied stress on the fuel cell and consequently reduces the hydrogen consumption.

“…It is noted in Mayer et al (2012) that high power lithium-ion batteries cost more than FC system (twice) for electric vehicle application. Also, one of the main challenges in PEM FC automobile markets is the premature degradation (aging) of the FC systems (Herb et al , 2013). This pushes experts to favor the FC system than the battery in a hybrid source, especially where the DOD is limited to low rates (guarantee of maximizing lifespan) and battery power rates are respected.…”

Purpose The purpose of this paper is to propose and compare two energy management strategies (EMSs). First, a classic method based on frequency separation with fixed limits on fuel cell (FC) power is presented and tested. Then, the improvement of the classic strategy is developed and implemented when the main enhancements are its ease of implementation, hydrogen economy and extending hybrid source lifetime. Design/methodology/approach The proposed EMS is developed using an online variable power limitation of the FC depending on the battery state of charge while ensuring that the energy of batteries remains in its operating depth of discharge (DOD) range. Findings In the objective to show the benefits of the developed strategy, a comparative analysis was conducted between two strategies. The simulation and experimental results show the effectiveness and gains obtained by the improved energy management system (IEMS) in terms of fuel economy (13 per cent) and decreasing the applied stress on the FC (22 per cent) which leads to a longer life span of the whole system. Originality/value The proposed approach is developed and tested by simulation. To confirm it, a test bench has been assembled as hardware in the loop (HIL) real-time system. The presented experimental results confirm the efficiency and show the providing gains of the IEMS.

“…Environmental problem and energy shortage are two major issues in our society, and it is imminent to develop clean and pollutionfree energy. The fuel cell is one of the promising energy sources due to its high efficiency and non-pollution [1], and it has a very high value of applied research in the field of DC microgrid and electric vehicles [2]. Fuel cell vehicles have the following advantages: clean electrical energy generation with zero emissions, high energy conversion efficiency, and a higher range [3][4][5].…”

In order to meet the requirements of the fuel cell stack power interface converter applied in the fuel cell vehicles, a common ground wide voltage-gain range DC-DC converter is proposed. On the input voltage side, an interleaved structure is adopted in this converter to reduce the input current ripple. On the output voltage side, two series capacitors are combined with a diode-capacitor structure to improve the voltage gain and reduce the voltage stress of power semiconductors and capacitors. As a result, the efficiency and reliability of the proposed converter can be improved. The operating principle, steady-state characteristic, parameter design, efficiency calculation, and comparison with other converters are analysed. A 1.6 kW prototype of the proposed converter with the 400 V output voltage has been developed to validate the analytical results. Theoretical analysis and experimental results show that the proposed converter can meet the requirements of a fuel cell stack power interface converter and is suitable for use as a fuel cell stack power interface converter applied in fuel cell vehicles.
