Abstract

The embodiment of the invention discloses a cell deformation detection device and method, and a terminal; the cell deformation detection device comprises a deformation detection module and a control module; the control module and the deformation detection module are electrically connected; the deformation detection module is used for detecting cell deformations; the control module is used for determining whether the cell has deformation abnormity or not according to the deformation detection result of the deformation detection module; the deformation detection module and the control module arearranged, so the cell deformation detection device can have cell deformation detection and deformation abnormity determination functions, thus safely detecting cells.

Description

technical field [0001] Embodiments of the present invention relate to a display terminal, and in particular, to a battery deformation detection device and method, and a terminal. Background technique [0002] Terminal batteries such as lithium-ion batteries will generate a small amount of gas during charging. Usually, the gas generated during charging will be absorbed during discharging, so slight deformation such as swelling during use is allowed. [0003] However, in abnormal use scenarios, such as excessive charging current or excessive discharging current, a large amount of gas will be generated inside the battery due to serious heating, causing the battery to bulge rapidly and abnormal deformation, which will shorten the service life of the battery at least, and cause battery failure in severe cases. Explosion, threatening the personal safety of users. [0004] Existing terminals do not have the function of detecting whether the battery is abnormally deformed, and cann...
