Abstract:
1. A battery system, comprising: an all-solid-state lithium secondary battery (a) comprising a sulfide-comprising solid electrolyte material; at least one reducing device (b); and a signal outputting device (c), wherein the at least one reducing device (b) reduces a charge-discharge amount of the all-solid-state lithium secondary battery (a) if a temperature in an inside of the all-solid-state lithium secondary battery (a) reaches a first threshold value, wherein the signal outputting device (c) outputs a predetermined notification signal if the temperature in the inside of the all-solid-state lithium secondary battery (a) reaches a second threshold value, and wherein the signal outputting device (c) continues outputting the predetermined notification signal if the temperature, after reaching the second threshold value, falls below the second threshold value.
