Publication number: 20240047774Abstract: One embodiment of the present invention is to provide a highly safe monitoring system for a secondary battery which ensures safety by warning a user when detecting an abnormality in the secondary battery, for example, when detecting a phenomenon that impairs safety of the secondary battery in an early stage. The monitoring system uses an imaging device which captures images of an external view of the secondary battery. Furthermore, for facilitating an abnormality detection, temperature sensitive paint is either sprayed or applied on at least part of a surface of an exterior body of the secondary battery. In addition, a light source for irradiating the temperature sensitive paint with light is also provided. With this structure, the abnormal portion can emit light (or exhibit a color) in the case where abnormal heat generation occurs locally, whereby the imaging device can distinguish an abnormal portion from image data by the imaging device.Type: ApplicationFiled: December 2, 2021Publication date: February 8, 2024Applicant: Semiconductor Energy Laboratory Co., Ltd.Inventors: Takeshi OSADA, Yosuke TSUKAMOTO, Takayuki IKEDA
