초록
배터리는 ESS, 전기자동차 및 무정전 전원 백업 시스템 등의 다양한 분야에서 사용이 증가하고 있다. 납산배터리는 에너지밀도가 낮지만, 신뢰성이 높고 저가격의 이점으로 대용량 전력백업 장비에 가장 많이 사용되는 배터리이다. 배터리의 사용에 따라 노화가 진행되면 충전 가능 용량(SoH)이 줄어들게 되어 상태를 추정하는 것이 매우 중요하며, 배터리의 내부저항으로 SoH를 추정하는 방법을 많이 사용한다. 본 논문에서는 대표적인 대용량 무정전 전원장치인 IDC를 위한 배터리 모니터링시스템(BMS)을 제안하였다. 내부저항을 측정하는 간단한 알고리즘을 제안하고, BMS 시스템 구성을 위한 CPU 및 아날로그회로 구성과 신호처리 알고리즘에 대한 연산 블록도를 보였다. 실제 IDC 현장에 적용한 측정결과 사례를 제시하여 제안한방법의 유용함을 보였다.
Abstract
Batteries are being used in ESS, electric vehicles and uninterruptible power backup systems. Lead-acid batteries arethe most used batteries for high capacity power back up equipment due to their high reliability and low price advantages. It is very important to estimate the chargeable capacity(SoH), and many algorithms were proposed to estimate theinternal resistance of the battery. In this paper, the Battery Monitoring System(BMS) for high capacity uninterruptiblepower supply for IDC is proposed. A simple algorithm for estimating internal resistance was proposed. An computationalblock diagram of the proposed signal processing algorithm and BMS system configuration of CPU and analog circuitwere shown. The proposed method was proved useful by presenting data examples of application to actual IDC sites.
