Title: METHOD FOR DETECTING SWELLING OF RECHARGEABLE BATTERY, AND PORTABLE ELECTRONIC DEVICE
Abstract:
Provided is a terminal, comprising: a housing, the housing comprising a rear cover (260, 560) of the terminal; a rechargeable battery (190, 250, 350, 450) placed in an accommodating space (380, 480), in the housing, for the rechargeable battery, the rechargeable battery (190, 250, 350, 450) comprising a first surface and a second surface, and the first surface being close to the rear cover (260, 560) of the terminal; a first electrode and a second electrode, the first electrode and the second electrode being located at an inner side of the rear cover (260, 560) of the terminal; a conductive sheet (453) located on the first surface of the rechargeable battery (190, 250, 350, 450), the conductive sheet (453) being opposite the first electrode and the second electrode; a detector (691), an input end thereof being connected to the first electrode and the second electrode, and used for detecting a swelling state of the rechargeable battery (190, 250, 350, 450); and a processing unit (692) connected to an output end of the detector and used for controlling, based on the swelling state of the rechargeable battery (190, 250, 350, 450), the input of electricity into the rechargeable battery. The terminal can detect, in a timely manner, whether a battery is swollen.
