Abstract: An all-solid-state secondary battery system comprising: a sealed battery having formed by housing, in an outer package, a stacked battery; a jig adapted to constrain the sealed battery in the stacking direction; one or more contact pressure sensors provided at least either between an outermost layer surface of the stacked battery and the outer package or in the inside of the stacked battery; one or more gas pressure sensors provided in a space inside the outer package; and a control device adapted to stop charging by judging as an overcharge state only when the change in contact pressure sensed by at least one of the contact pressure sensors is equal to or more than a threshold value, and the change in gas pressure sensed by at least one of the gas pressure sensors is equal to or more than the threshold value.
