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.

“…The FCs are more appropriate for applications with long-term variations as an energetic source while batteries are more adapted for applications on the time scale of several minutes/seconds as a secondary source. 3 Several models of the FCEVs are commercialized on the market such as Toyota Mirai, Hyundai Tucson and Honda FCX Clarity. These vehicles have approximately similar characteristics with 100-kW power levels.…”

“…1,2 Furthermore, the FCEVs have some limitations in term of drive range, cost and fuel consumption. 3 Hybrid electric vehicles have more than one power source, which needs a management strategy to determine the mission profile of each source according to the load power and sources constrains. The energy management strategy (EMS) is considered as a main key of development of FCEV because it defines the fuel consumption and the energy storage source (ESS) lifetime.…”

This article presents a comparative study between the performances of different energy management strategies for hybrid energy storage source supplying electric vehicle. In our case, the hybrid supply is composed of fuel cell as an energy source and lithium-ion batteries as a power buffer. The two storage systems are connected to the DC bus via DC/DC boost converters. The used management strategies influence greatly the hybrid energy storage source performances. For this reason, a new online strategy is developed to improve the fuel consumption and the hybrid source lifetime. The performances (hydrogen consumption and applied stress on each source) of this new strategy are compared with those obtained with literature strategies for 700 km of range. Furthermore, an experimental validation of two online energy management strategies is carried out to validate the simulation results using 1-kW test bench. The experimental results prove that the developed strategy improves hydrogen consumption compared to the frequency strategy and it improves also the lifetime of the hybrid storage system.

“…Sizing seems to only influence the weight and volume of the hybrid storage system, nevertheless, the initial cost, life-cycle cost, battery lifespan, vehicle efficiency, and other elements are relative to sizing optimization. The procedure can be simple if it only considered the boundary conditions such as energy consumption, peak power, weight limitation, and terminal voltage [10][11][12]. Most of the sizing is based on certain EMS.…”

In order to design a well-performing hybrid storage system for trams, optimization of energy management strategy (EMS) and sizing is crucial. This paper proposes an improved EMS with energy interaction between the battery and supercapacitor and makes collaborative optimization on both sizing and EMS parameters to obtain the best working performance of the hybrid storage system. This paper demonstrates the whole process of the improvement of the EMS, the traction calculation, the parameter optimization, and the sizing optimization based on real tram and line conditions. The improved strategy is proven to be superior as it guarantees normal operation and avoids shutdown conditions when the supercapacitor is at a low voltage. Furthermore, the optimized sizing result largely decreases the weight of the storage system and obtains a long battery lifespan.
