This system is designed for outdoor application in un-electrified remote rural areas. This system is an ideal application for house or village street lighting. The system is provided with battery storage backup sufficient to operate the light for 7-8 hours daily. The project is about to develop and fabricate the circuit that can charge the lead acid battery during day time by using solar as the...

A novel distributed transient thermal model is proposed to investigate the thermal behavior of nickel emetal hydride (NiMH) batteries under fast-charging processes at constant currents. Based on the method of integral transformation, a series-form solution for the temperature field inside the battery core is obtained that takes account for orthotropic heat conduction, transient heat generation,...

The economic operation of battery swapping stations (BSSs) is significant for the promotion of large-scale electric vehicles. This paper develops a linear programming model to maximize the daily operation profits of a BSS by considering constraints of the battery swapping demand of users and the charging/discharging balance of batteries in the BSS. Based on the BSS configuration and data from e...

Electric vehicles (EVs) are becoming popular in the United States. Battery EVs, powered exclusively by electricity, draw more attention because they emit zero exhaust fumes, transfer energy efficiently and can be more economical compared with internal combustion automobiles. This paper presents a comprehensive analysis of the real-world charging, driving and energy consumption patterns of elect...

Li-ion batteries are widely used in a variety of products ranging from consumer gadgets such as cell phones and laptops to electric vehicles. Their popularity can be attributed to high energy density and minimal maintenance. Charging these batteries can take anywhere from a few hours for low powered gadgets to many hours for high powered automobiles. Although theoretically possible, fast chargi...

Smart grids have been introduced to replace conventional power distribution systems without real time monitoring for accommodating the future market penetration of plug-in electric vehicles (PEVs). When a large number of PEVs require simultaneous battery charging, charging coordination techniques have become one of the most critical factors to optimize the PEV charging performance and the conve...

Battery maintainers are widely used in marine and ground vehicles whose batteries have cycles of operation involving long periods of non-active life. Durability of such batteries, without proper maintenance, does not exceed one year. Extension of the battery life-time requires very thorough monitoring and periodic, preferably automatic recharging to replenish lost charge due to battery selfdisc...

A battery-charging system for stand-alone photovoltaic (PV) applications is presented. Advantages of the proposed method are: better exploitation of the available PV energy by means of a maximum power point tracking (MPPT) technique employed in the control algorithm, increased battery lifetime due to higher level state of charge operation, and the charging control process does not depend on acc...
