This paper presents a review and analysis of failure detection methods of composites materials systems and development and application of a bamboo bicycle. The paper begins by presenting the current market condition of composites materials and in particular, carbon fibre and carbon fibre reinforced plastic (CFRF). The work proceeds to investigate the failure detection methods that have been applied...
This paper provides a simple and advanced technique to monitor and predict the state of health (SOH) and the open circuit voltage (OCV) for valve regulated lead acid (VRLA) battery cells. The underlying principal of the technique described in this paper employs a mathematical model that can simulate different pore geometries shape and a simple equation to predict the equilibrated cell voltage after...
This paper presents an innovative electronic-magnetic gearing motor. The motor is designed and tested. This electronic-magnetic gearing (EMG) assembles parallel, serial or hybrid connections of stator windings into gears to accommodate the different speed and torque demands in the drive cycle. The objective of EMG is to increase the maximum speed and maximum torque range of the motor. A 1.5kw prototype...
This paper describes the design and implementation of an open circuit voltage (OCV) prediction mechanism for Li-ion based battery systems. This approach involves the development of a simulation model incorporating Li-ion cells, modules and later the PV-battery system. The simulation model is used to analyse the effect of the prediction mechanism and is validated with the experimental data obtained...
The optoelectronic coupling for a pulse-driven Josephson junction array (JJA) for use as a quantum voltage synthesizer has been designed. This system uses optoelectronic components to drive a group of JJAs in parallel. Since the drive system is electrically isolated from the JJAs, they can be connected in series, leading to a higher output voltage. A thin film circuit, including interdigitated capacitors...
This paper investigates the design of an optimal battery management system for hybrid electric vehicles to allow performance improvements. Battery management systems are an important subsystem for hybrid electric vehicles, which ensure that the batteries are operating within the specified safe operating conditions. Thus, the design of a battery management system plays an important role on battery...
