Abstract
A system and method of estimating the state of health of an all-solid-state battery are provided to detect the amount of hydrogen sulfide that is generated in all-solid-state battery cells and using the amount as a factor for estimating the state of health of the battery. The method of estimating a state of health (SOH) of an all-solid-state battery includes detecting whether hydrogen sulfide is generated in each cell of the all-solid-state battery, and estimating the state of health of the all-solid-state battery corresponding to an amount or an increase rate of generated hydrogen sulfide based on data prepared in advance.
