Abstract
The invention relates to a method for operating a battery system (EB), preferably a lithium-ion battery system, containing at least one battery device, wherein in the case that a safe state of the at least one battery device is brought about from an irregular operating state of the at least one battery device, a current state of the at least one battery device is continuously checked and evaluated by means of at least one component (CSC) of the battery system and the bringing about of the safe state is performed in dependence on the current state of the at least one battery device or an environmental state of the at least one battery device, wherein in particular after the safe state of the at least one battery device has been brought about, hazard information is transmitted to a battery management system (BMS) by means of the at least one component (CSC) of the battery system (EB), wherein the hazard information in particular is hazard information about the current state of the at least one battery device and/or about the environmental state of the at least one battery device and/or about the fact that the safe state of the at least one battery device is present.
