| Abstract |
Recently, electrical energy storage system(ESS) have been used in a wide range of applications, for example, in connection with renewable energy (Photovoltaic power generation, wind power generation, etc.) to improve energy efficiency, frequency regulation and power stabilization. Also, mobile devices such as portable IT devices (smart phones, notebooks, smart mobility, etc.) demand is rapidly increasing. As a result, the supply of battery energy storage system(BESS) based on lithium batteries also rapidly increasing. In addition to that fire accidents have been increasing due to complex problems such as ESS management, poor operation and inadequate installation environment. In this paper, protection circuit module(PCM) and battery management system(BMS) of battery energy storage module(BESM) in BESS has contemplated. In connection with the common problem of thermal runaway of battery management, the safety enhancement for thermal stability is simulated through temperature sensing for individual cells. To this end, embedded-based multi-channel temperature monitoring compensates the limitation of temperature monitoring has battery protection devices(PCM and BMS etc.). Also, to overcome the problem of rapidly the battery life aging due to over-voltage and under-voltage protection of transient range based on PCM, we propose a BMS using embedded module and PCM with module level voltage & current management function. |
