Abstract
This study suggested the evaluation model for Lithium-ion battery life. Considering the trend that eco-system has become serious concern against the global environment, Lithium-ion battery is most promising represented by Electric Vehicle. However, estimation method for residual battery performance has not been established. Therefore, asset value and payout period are forced to be unsure, namely, the spread of Lithium-ion battery has been prevented. This evaluation model developed in this study can calculate the residual battery performance by degradation rate database and assumed battery use pattern. The degradation rate database was established using charge–discharge test of Lithium-ion battery cell. By applying the database, the residual battery performance can be calculated under any battery use scenario. This model was validated by comparing the experimental data with the simulation result.
