Emergency l ight ing systems are frequently employed as a required safety feature within business premises. These systems comprise essentially of a control circuit, a battery pack, a trickle charging circuit, and either an in-built incandescent lamp, or an inverter that will allow the battery supply to drive the existing fluorescent tubes. It is the latter version, and the requisite DC-AC inver...

Abstract In special vehicles, single cells or battery packs often provide energy for the vehicle after being connected in series and parallel. However, due to influence of production process use environment, inconsistencies may occur pack, resulting a decline performance pack. Therefore, balance management system has increasingly become an indispensable module system. It can perform real-time b...

As lithium-ion battery (LIB) cells degrade over time and usage, it is crucial to understand their remaining capacity, also known as State of Health (SoH), inconsistencies between in a pack, cell-to-cell variation (CtCV), appropriately operate maintain LIB packs. This study outlines efforts model pack SoH CtCV nickel-cobalt-aluminum (NCA) lithium-iron-phosphate (LFP) packs consisting four series...

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...
