The exchange of the energy storage unit from an electric vehicle is considered as an alternative to in-vehicle battery charging or regeneration. If the exchange process is mechanically assisted or automated, the exchange can be accomplished in much less time than that required for in-vehicle charging. Many means for accomplishing battery exchange have been proposed or attempted, with various de...

This paper presents the design and construction of charge controller for wind energy source. The charge controller is a small prototype that is suitable to charge small battery.

The charge controller is designed using PIC 16F877A microcontroller, liquid-crystal display (LCD), silicon-controlled rectifier (SCR), rectifier diodes...

This report describes the design, construction and test results of an inductively coupled battery charger for robot power supplies. The system should be capable of charging several robot batteries at once from a contactless charging station. The charger should be capable of providing different charging conditions to several different kinds of battery at once. The system should be capable of cha...

The greenhouse gases and air pollution generated by extensive energy use have exacerbated climate change. An electric-bus (e-bus) transportation system favors reducing pollution and carbon emissions. This study analyzed the minimization of construction costs for an all batteryswapping public e-bus transportation system. A simulation was conducted according to existing timetables and routes. Day...

This paper proposes a novel design for a solar-powered charger for low-power devices. The level of the charging current is controllable and any residue power is saveable to a rechargeable 9V battery. Two power sources (AC and solar) are used, and two charging speeds are possible. Quick charging is 20% of the battery output current (almost 180mA/hr) so the current is limited to 34 mA. Two types ...

The portable fuel-cell powered battery charging station provides a good solution to recharging batteries in field applications. This paper presents the design and testing of control strategies for this system using the Virtual Test Bed (VTB). The VTB provides a unique environment to model interdisciplinary components, to rapidly prototype the control system, and to simulate complex systems. In ...

This paper contains the design of a three stage solar battery charge controller and a comparative study of this charge control technique with three conventional solar battery charge control techniques such as 1. Constant Current (CC) charging, 2. Two stage constant current constant voltage (CC-CV) charging technique. The analysis and the comparative study of the aforesaid charging techniques ar...

A study on plug-in electric vehicle (PEV) charging load and its impacts on distribution transformers loss-of-life, is presented in this paper. The assessment is based on residential PEV battery charging. As the exact forecasting of the charging load is not possible, the method for predicting the electric vehicle (EV) charging load is stochastically formulated. With the help of the stochastic mo...

A charge equalisation circuit is proposed for the series-connected battery bank in a serial charging scheme. The charge equalisation is based on buck–boost conversion, and hence is essentially nondissipative. The subcircuit associated with each battery acts as a current diverter to transfer the excess charging current from the fully charged batteries to the flat ones. By dynamic redistribution ...
