Low Cost Battery Management System

Abstract

This article addresses the issue of battery management system for the development of an electric scooter. Considering developing electric vehicle needs big financial supports, the development of the electric scooter is an educational project conducted at the Technical University of Ostrava. Electric scooter is equipped with a brushless motor with permanent magnets and engine controller, measuring and monitoring system for speed regulation, energy flow control and both online and off-line data analysis, visualization system for real-time diagnostics and battery management with balancing modules system. Implementing these devices to develop an electric vehicle brings a wide area of scientific research. As a part of the project for electric scooter development, a battery management system which oversees the running parameters of the accumulator was developed at the university. The function of the balance module, especially its software, will be described in this article.
