In this study, the battery pack and ESP32 microcontroller-based management system (BMS) design for electric bicycle have been carried out. The software updates were realized when was in box, thanks to built-in Wi-Fi feature of ESP32. voltage values read precisely, a stable BMS created with 12-bit ADC-based controller. had temperature control from 7 different points. data received DS18B20 digita...

In recent year, the development of hybrid renewable energy sources has the important role of power generation. This paper focused on design of hybrid PV / Wind power system and its battery management system. The fuzzy logic control based battery management system has been designed for effective power utilization. The proposed control to operate the battery charging and discharging mode during n...

In this paper, we propose a wireless system discovery scheme capable of supporting effective device power management by employing a battery-efficient wireless network scanning procedure. Multi-mode terminals must be able to discover other wireless systems and, above all, to execute an inter-system handover in the heterogeneous wireless network environment. The existing methods introduced in rec...

in the present study, a model of a large lithium polymer (li-po) battery for use in the simulation of hybrid electric vehicles (hevs) is developed. to attain this goal, an equivalent circuit (ec) consisting of a series resistor and two rc parallel networks is considered. the accuracy and the response time of the model for use in an hev simulator are studied. the battery parameters identificatio...

A new valve regulated lead-acid (VRLA) gel motive power battery and PV system power center have been tested in the laboratory and at a PV hybrid telecommunication site. The power center provides battery charge control, system remote communications, and data acquisition at the field test site. Extensive laboratory and field-test data were used to improve battery performance by optimizing, regula...

In this paper, battery/ultracapacitor hybrid energy storage system (HESS) is proposed for electric vehicles, it is used to large dc-dc converter by using ultra capacitor and battery. It is also use the dc link for the purpose of maintain the peak voltage value. By the help of battery and ultracapacitor they are operate. The battery is used to charging the capacitor in case of discharge the capa...

This paper proposes an approach for the hybrid solar photovoltaic and wind power system in Battery management for stand-alone applications. Battery charging process is non-linear, time-varying with a considerable time delay so it is difficult to achieve the best energy management performance by using traditional control approaches. A fuzzy control strategy for battery charging or discharging us...
