Abstract

A gas estimating unit configured to estimate an amount and a composition of a gas generated inside a secondary battery includes at least one processor and at least one memory electrically coupled to each other. The at least one processor is configured to detect a presence or absence of a gas generating period. The gas generating period is a period for which the gas is generated inside the secondary battery while the secondary battery is in one or both of an overcharging state in which the secondary battery exceeds a voltage limit and a high-temperature state in which the secondary battery exceeds a temperature limit.
