Abstract
A battery system that can prevent a burst of a battery and a battery safety alarm system therefor are provided. A battery system includes a lithium ion battery formed in a cylindrical shape and including an organic electrolytic solution as an electrolyte. A laser beam source emits a laser beam. An optical fiber of a single mode is wound around an outer circumferential portion of the lithium ion battery in a plurality of lines and via which the laser beam emitted from the light source is transmitted. A detector receives the laser beam transmitted via the optical fiber and detects abnormality of the lithium ion battery on the basis of a loss of the laser beam due to the optical fiber or a change with time of the loss. An alarm warns a user of the abnormality when abnormality of the lithium ion battery is detected by the detector.
