Beschreibung
Zusammenfassung:	The invention relates to an internal gas estimation device for a secondary battery and a vehicle. The internal gas estimation device for the secondary battery can further reduce cost and estimate the components and the amount of gas generated in the secondary battery. An internal gas estimation device for a secondary battery according to one embodiment of the present invention estimates the amount and composition of an internal gas generated inside a rechargeable secondary battery, the internal gas estimation device comprising: one or more processors; and one or more memories electrically connected to the processor, the processor detecting at least the presence or absence of a gas generation period during which the secondary battery is in an overcharged state of the secondary battery exceeding an appropriate use upper limit and a high temperature state of the secondary battery exceeding the appropriate use upper limit, the processor estimates an amount and a composition of the internal gas based on a result o
