In these days, there is a tendency that research of Prognostics and Health Management (PHM) of Lithium-ion battery that prevent accidents in advance by predicting the Remaining of Life (RUL). However, there is a difficulty in battery evaluation for composite condition of an operating conditions and a storage conditions, due to the time consuming. Research on the RUL of Lithium-ion battery in composite condition are progressing by combining an operating condition and a storage condition. Conventional method such as Miner’s Rule may not fully meet the needs of battery evaluation for RUL. Because it does not take into account overloads caused by a variable amplitude loading history. In order to solve the problem of accurately predicting the RUL of Lithium-ion battery, two approaches applied to predicting the RUL of Lithium-ion battery. We demonstrate the usefulness of two proposed methods by comparing with real-data of composite condition.
