전력변환 시스템용 고 신뢰성 BMS

Abstract

The Global Environment Agency's CO2 emission restrictions have increased in their complexity over the last several years. In particular, the International Maritime Organization’s (IMO) 2020 deadline for a fuel sulfur dioxide cap of 0.5% means there is growing impetus for environmental and safety systems. Most of all, electric vehicles and electric ships are becoming the most eco-friendly vehicles of the future. The role of the battery of electric transportations is important to improve efficiency and safety, This paper presents high-reliability battery management system which estimates OCV, during battery operation. Even the battery problems are occurred, high-reliability BMS supplies sustainable DC power source. In addition, how it can be useful in monitoring and control is discussed. Advanced high-reliability BMS is expected to reduce further accident from battery malfunction.
