BATTERY LIFE ESTIMATION METHOD AND BATTERY LIFE ESTIMATION DEVICE |
摘要 |
According to an embodiment, a battery life estimation method includes: calculating, for a secondary battery, battery characteristic data at a present time including at least an internal resistance value; storing use condition data including a temperature time distribution and a current value time distribution during an estimation period and a degradation characteristic map representing a distribution of degradation constants with respect to battery voltages and temperatures; and estimating a degradation amount by integrating residence times on a battery voltage temperature plane in the degradation characteristic map based on the battery characteristic data at the present time and the use condition data. |
