Development of arduino-based battery management system for lithium-ion battery using pico-hydro generator from rainwater system

Abstract

The lack of electricity access in some rural areas has become a significant concern, and unless cost-effective solutions like Pico-Hydro generators are adopted, this issue will worsen. This research focuses on designing and implementing an Arduino-based Battery Management System (BMS) for Lithium-Ion batteries integrated with a Pico-Hydro Generator powered by a rainwater system. The study aims to develop a control system for the rainwater tank, create a BMS for battery management, and test the system to achieve a 5V-12V power bank output. Through 15 trials, the BMS successfully regulated current values and demonstrated stable performance during the testing procedure, with the voltage output ranging from 5.2 V to 5.29 V (average: 5.25V), the current output varying from 3.24 A to 3.41 A (average: 3.3 A), and the power output ranging from 16.85 W to 18.04 W (average: 17.37 Watts). Furthermore, the BMS successfully charged a 3600 mAh battery within an estimated 3.52 hours. The researchers suggest raising the water tank's height to at least 6 meters, increasing the battery's mAh rating for improved power storage, and proposing a drainage system to recycle water from the tank for reuse, requiring further investigation and exploration.
