In this paper, we present a system to estimate the health of a lead-acid car battery and warn the driver of upcoming battery failure in the near future. Most existing lead-acid battery state of health (SOH) estimation systems measure the battery impedance by sensing the voltage and current of a battery. However, current sensing is costly for parts and/or labor. A method to estimate SOH by sensing...
A power conditioning circuit for an electromagnetic energy harvesting device which is designed to harvest energy from the suspension of a freight train is presented in this paper. The electromagnetic transducer, which converts linear vibrations into electricity, is briefly discussed in this paper. After the output features of the transducer are studied, a buck-boost converter is designed to present...
Plug-in hybrid electric vehicles (PHEVs) are an emerging technology in the market and are helping to offset the negative effects of existing transportation methods that primarily rely on fossil fuel sources. As PHEVs are being introduced into the market, renewable energy sources such as solar power are taking a larger part in the energy sector. A need for high efficiency battery charging is required...
Photovoltaic modules have become a viable renewable energy source for energy systems in communications, commercial, and residential applications. Plug-in electric or hybrid vehicles appear in the market as an emerging technology to reduce carbon emissions and improve energy efficiency. PV modules and plug-in hybrid vehicles interact with the power grid as energy source and energy storage elements,...
