摘要： An all-solid-state battery system includes an assembled battery configured by connecting a plurality of cells, and a control device that performs charge control and discharge control of the assembled battery. Each of the plurality of cells is an all-solid-state battery. The control device is configured to perform an equalization process of evenly approximating the amount of stored electricity between the cells in the plateau region in the relationship between the voltage and the amount of stored electricity of the assembled battery in the charge control or the discharge control of the assembled battery.

摘要： A battery system includes: a battery case; a battery housed in the battery case, the battery being composed of a sulfide-based all-solid-state battery; a first detection unit located on a bottom surface of the battery case inside the battery case and configured to detect hydrogen sulfide; a second detection unit located vertically above the bottom surface inside the battery case and configured to detect hydrogen sulfide; and a control device. The control device includes an abnormality processing unit configured to perform an abnormality process based on detection results from the first detection unit and the second detection unit. The abnormality processing unit is configured to perform a first abnormality process when hydrogen sulfide is detected only by the first detection unit, and to perform a second abnormality process when hydrogen sulfide is detected by the second detection unit.

摘要： A driving apparatus is controlled by using a driving command that is obtained by applying an accelerator operation amount to a relation between the accelerator operation amount and the driving command for the driving apparatus, and the relation is set by using a distribution of usage of the driving command by a driver such that a gradient that is a change in the driving command with a change in the accelerator operation amount in a high usage range including a value having a longest usage time among values of the driving command is less than the gradient in a range other than the high usage range.
