The battery thermal management system (BTMS) utilizing phase change materials (PCM) has shown promising performance in high heat flux dissipation. However, conventional PCM systems do not fully exploit the latent properties of paraffin wax to enhance cooling efficiency. To address this issue, paper proposes a novel multilayer composite material for BTMS, aiming improve and overcome low conducti...

1. Project Goals The objective of this task is develop (or adopt from literature) a model that estimates the battery degradation as the function of the DESD use profile. The off-line degradation model supports system cost-benefit studies while the on-line implementation resides on the DESD ARM board (BeagleBoneBlack), and supports the IEM application. The on-line model will be implemented on th...

As part of the ongoing effort to be independent of petroleum resources and to be free from pollutant emission issues, various electric vehicles have been developed and tested through their integration with real world systems. In the current paper, yet another application specific EV for public transportation, an electric bus, is introduced and explained with results from the pilot test program ...

This paper explains the design of a standalone Solar/ Fuel cell/ Battery hybrid power system which involves the design of individual systems along with the power management circuit. The variation of solar insolation according to the time and the Maximum Power Point Tracking’s (MPPT) Perturb and Observe (P&O) algorithm is considered in the design of solar system. Similarly, the control of fuel f...

This paper proposes an energy management strategy for hybrid power system HPS which is composed of a photovoltaic generator, wind turbine, fuel cell generator and NaS battery storage device, feeding a type house. This strategy is based on Fuzzy Logic Control technique. The hybrid power system is sized to provide the energy demand of the inhabitants of the house and if there is an extra power ge...

A portable proton exchange membrane (PEM) fuel cell operates at room temperature, has an energy density which is 4 to 6 times larger than that of a Li-ion battery, and thus is a promising next generation power source for power-hungry portable devices. However, in spite of the high energy density, fuel cells have limited power capacity and cannot respond to sudden changes in the load. Thus, a sy...
