As an alternative to the photoelectrochemical water splitting for use in the fuel cells used to generate electrical power, this study set out to develop a solar energy rechargeable battery system based on photoelectrochemical water oxidation. We refer to this design as a "solar water battery". The solar water battery integrates a photoelectrochemical cell and battery into a single device. It us...

This paper proposed a optimal strategy for coordinated operation of electric vehicles (EVs) charging and discharging with wind-thermal system. By aggregating a large number of EVs, the huge total battery capacity is sufficient to stabilize the disturbance of the transmission grid. Hence, a dynamic environmental dispatch model which coordinates a cluster of charging and discharging controllable ...

An electric vehicle (EV) battery charging station (EV-BCS) based on a bipolar dc power grid is presented in this paper, which capable of delivering to the (vehicle-to-grid – V2G mode), and directly exchange between different EVs connected EV-BCS (vehicle-to-vehicle V2V besides traditional operation (grid-to-vehicle G2V mode). The three-level bidirectional buck-boost dc-dc converters has modular...

This article gives an overview of the Electric Energy Storage (EES) library, which is proposed for inclusion in the Modelica Standard Library. The library contains models with different complexity for simulating of electric energy storages like batteries (single cells as well as stacks) interacting with loads, battery management systems and charging devices. It is shown how the models are defin...

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 maximum charging current of the charge controller is about 7 A. 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...

This paper describes the integration of power electronic and energy storage applications in distribution substations. Auxiliary circuits must provide motor-driven power switches, protection relays and telecontrol systems with constant power supply, thus minimising power outages and their negative effects on consumers. Requirements on the apparatus are proportional to the distributed voltage lev...

It has been shown that none of any energy sources which own high specific energy or high specific power, but not both, can solely fulfil all the demands of hybrid electric vehicle (HEV) in some circumstances. In this paper a simulation model for battery/ultra-capacitor hybrid energy storage system (B/UC HESS) was presented by Matlab/Simulink. Based on the model a low-pass filtering control stra...

The central part of an energy storage system is the DC-DC converter which connects the ultracapacitor pack or the battery pack and a DC bus of an energy system. In this paper the bi-directional converter which operates in discontinuous conduction mode is designed in order to reduce the costs and remove the current control loop in each phase. High current ripples associated with this mode operat...
