Non-uniformity of Lithium-ion cells in a battery pack is inevitable and has become the bottleneck to the pack capacity, especially in the fast charging process. Therefore, a balancing approach is essentially required. This paper proposes an active online cell balancing approach in a tfast charging process using the state of charge (SOC) as balancing criterion. The goal of this approach is to co...

Beberapa daerah pedesaan di Indonesia masih memiliki rasio elektrifikasi yang rendah karena letak geografis menyulitkan dalam membangun jaringan listrik. Alternatif solusi agar mendapatkan energi listrik adalah menggunakan panel surya. Namun, keluaran dari surya bersifat intermitten, sehingga memerlukan tempat penyimpanan atau baterai. Teknologi baterai terkini lithium ion diklaim lifetime lama...

An electric vehicle is a type of that uses motor and battery pack instead an internal combustion engine. Power given from battery-pack rather than petrol. This saves money has smaller impact on the environment as well. There are few barriers for rapid adoption vehicles, like lack charging infrastructure, limitations technology high purchase costs. In this project, I am going to converting petro...

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...

Modern automobiles are entirely controlled by electronic circuits and programs which undoubtedly exposes them to the threat of cyberattacks. Alongside, there is a potential for massive growth in electric vehicle (EV) adoption. The cyber vulnerabilities are magnified with electric vehicles because of the unique and critical risks that entail most EV batteries. EV battery packs provide ‘limited d...

We present results of a math-based model of a battery electric vehicle (BEV) designed in MapleSim1. This model has the benefits of being described in a physically consistent way using acausal system components. We used a battery model by Chen and Rinćon-Mora to develop a math-based model of a complete battery pack, and developed simple power controller, motor/generator, terrain, and drive-cycle...

This paper describes the development of a Battery Management System (BMS) State of Charge/Health (SOC/SOH) algorithm that was developed and proven for three different lithium ion based cell chemistries (nanophosphate, lithium manganese oxide, lithium iron phosphate). In addition, a universal BMS architecture based on this algorithm was developed that can support other chemistries, capacities, a...
