Sliding mode control for fuel cell supported battery charger in vehicle‐to‐vehicle interaction

In typical vehicle‐to‐vehicle (V2V) charging systems, energy transfer is provided from a battery electric vehicle (BEV) to charge the energy storage unit of another BEV. In this study, the utilization of a fuel cell electric vehicle (FCEV) as an energy provider is purposed to charge the energy storage unit of a BEV in V2V interaction. Since FCEVs are filled with hydrogen, it also eliminates the disadvantages of traditional BEV energy providers, such as a reduction in the amount of stored energy and the need for more time to charge fully. In the designed system, a new plug‐in external V2V battery charger topology supported by an FCEV has been proposed to supply electrical energy. In order to control the energy transfer between electric vehicles (EVs), a sliding mode controller is adapted to manage the external converter interface located between vehicles. The designed controller shows improved robustness against the system dynamics uncertainties and disturbances generated by a variety of internal and external causes. In the designed section, a proton exchange membrane fuel cell with the maximum operational rating of 75 kW is used as an energy provider to feed consumer loads. The proposed system has been designed and analyzed for several loading situations from 20% to 100% loading and obtained performance results have been compared with a conventional controlled V2V battery charger system. The case studies validate that the proposed V2V charger system gives better results than the conventional controlled FC‐supported V2V. The stability and robustness of output electrical waveforms are better for the designed system. In this context, the tracking error of the conventional controller is about 8% larger than that of the designed sliding mode control for dynamic load changes. The sliding mode controller has a faster settling time (approximately 0.12 s) in comparison with the conventional controlled V2V charger system. Also, mean absolute error values verify that the designed sliding mode controller operates smoothly under all cases except load transition compared to the typical control method. As a result, the case studies show that satisfactory results have been obtained for the designed system.

Long-Range Li-Ion 3D Diffusion in the High-Temperature Hexagonal Phase of LiBH₄ Studied by ⁷Li Pulsed Field Gradient NMR and MD Simulations

Lithium diffusion pathways have been determined in three dimensions using molecular dynamics simulations and 7 Li pulsed-field gradient spin-echo (PGSE) NMR diffusometry. Lithium ions arrange in multiple hexagonally arranged and intertwined columns oriented at different angles on (001) surfaces. It has been found that lithium jumps are characterized by zig−zag patterns with the main diffusion tensor axis aligned along the [001] direction. Additional diffusion tensor dimensions appear in the (001) planes through multiple jumps along the [001] direction. The simulation results were confirmed by non-linear spin-echo attenuation in the 7 Li PGSE NMR experiment and three-dimensional diffusion model developed for Li + -ion conductivity. The exact values of the main diffusion tensor components D ⊥ = (D 11 + D 22 )/2 and D ∥ = D 33 were derived from the uni-dimensional projection of diffusion tensor under macroscopic powder averaging condition. The single ionic jump in the [001] direction was related to D ∥ , while translation on the ( 001) plane required at least two jumps through the zig−zag path and related to D ⊥ . Lithium diffusion in the [001] direction is faster than that in the (001) planes. The activation energies for D ⊥ and D ∥ were determined between 105 and 130 °C and varied between 0.47 and 0.51 eV, which suggests that both diffusion coefficients are related to the same mechanism of the jump. Pre-exponential factors for D ∥ and D ⊥ were also determined and equal to 4.8 × 10 −6 m 2 s −1 for D ∥ and 3.8 × 10 −7 m 2 s −1 for D ⊥ , respectively, which confirms that molecular translations between (001) surfaces are not performed in a single jump.
