Introduction

Rancang bangun sistem manajemen dan proteksi pada baterai 48 v 12 ah. Rancang bangun Sistem Manajemen Baterai (BMS) & proteksi baterai Li-ion 48V 12Ah sepeda listrik. Perpanjang usia dengan proteksi tegangan/arus berlebih & monitoring IoT.

Abstract

Batteries, particularly lithium-ion, are a key component in energy storage due to their high energy density, long lifespan, and fast rechargability. fast recharge capability. In addition to their efficiency, we must pay attention to factors factors that can affect the life and service life of the battery. For this reason, the author will create a battery management and protection system in order to extend the life of the battery itself. the service life itself. In order to support this tool, a monitoring monitoring system that will be made based on IOT. Protection that will be made is over voltage protection, low voltage protection, over current protection, and over charge protection. also over charge protection. Protection will be made by looking at the parameters displayed by ESP32. ESP32 will use PZEM-017 sensor and shunt resistor as voltage and current sensors. as voltage and current sensors. In this case, the battery in question will have a voltage of 48 Volts and is intended for electric bicycle batteries.

Review

The article, titled "RANCANG BANGUN SISTEM MANAJEMEN DAN PROTEKSI PADA BATERAI 48 V 12 AH," tackles a highly relevant and critical area in modern energy storage: the development of a Battery Management System (BMS) for lithium-ion batteries. Given the pervasive use of Li-ion technology in applications such as electric bicycles, as indicated by the abstract, ensuring their longevity, safety, and optimal performance is paramount. The authors' stated goal of designing a comprehensive management and protection system directly addresses these crucial concerns, aiming to mitigate factors that can degrade battery life and serviceability. The abstract effectively outlines the core functionalities of the proposed system, focusing on essential protection mechanisms. These include over-voltage, low-voltage, over-current, and over-charge protection, which are all vital for safe and reliable battery operation. A commendable feature is the integration of an IoT-based monitoring system, leveraging an ESP32 microcontroller in conjunction with a PZEM-017 sensor and shunt resistor for voltage and current sensing. This modern approach to data acquisition allows for remote monitoring and potentially more proactive management of the 48V 12Ah battery pack, suggesting a practical and implementable solution for enhancing battery reliability and extending its operational lifespan. While the abstract provides a strong overview of the proposed system, several areas could benefit from further elaboration to fully convey the scope and innovation of the work. Notably, for a multi-cell 48V battery pack, the abstract does not explicitly mention the implementation of a cell balancing mechanism, which is fundamental for maximizing the lifespan and usable capacity of such packs. Furthermore, a discussion on thermal management, a critical aspect of Li-ion battery safety and performance, appears to be absent. Future iterations of the abstract, or the full paper, should also detail the specific Li-ion chemistry used, elaborate on the algorithms governing the stated protections, and provide insights into the expected performance metrics or validation methodologies used to substantiate the claim of "extended life."
