Intelligent Battery Management System Analyzing & Optimizing of Multicell Battery Voltage
Journal Title: The International Journal of Technological Exploration and Learning - Year 2013, Vol 2, Issue 6
Abstract
The battery management system (BMS) is a critical component of electric and hybrid electric vehicles. The purpose of the BMS is to guarantee safe and reliable battery operation. To maintain the safety and reliability of the battery, state monitoring and evaluation, charge control, and cell balancing are functionalities that have been implemented in BMS. As an electrochemical product, a battery acts differently under different operational and environmental conditions. The uncertainty of a battery’s performance poses a challenge to the implementation of these functions. This paper addresses concerns for current BMSs. State evaluation of a battery, including state of charge, state of health, and state of life, is a critical task for a BMS. Through reviewing the latest Atmel ATA6870 IC technology for the state evaluation of batteries, the future challenges for BMSs are presented and possible solutions are proposed as well.
