The invention discloses a method and an apparatus used for detecting the heat resistance safety property of a cell phone battery. The method comprises steps that: a, the cell phone battery is fully charged; b, a heat-generating body is prepared, and temperature-measuring probes are respectively connected to the heat-generating body and to the cell phone battery; c, the heat-generating body is heated to a temperature of 245-250 DEG C; the cell phone battery requiring detection is placed at the center of the heat-generating body, and is naturally cooled to room temperature; the changes of the battery are observed; and d, the changes of the battery are observed and recorded. When an existing cell phone battery is used, high-temperature resistance detection is not carried out. The implementation of the invention assists in filling the gaps. With the detection method provided by the invention, qualified cell phone batteries can be prevented from exploding, combusting, and splashing electrolyte under high temperatures when applied in batches. Therefore, serious accidents caused by explosion, combustion and electrolyte splashing can be prevented, and personal safety of consumers can be ensured.
Description
technical field [0001] The invention relates to a mobile phone battery testing method, in particular to a method and device for testing the temperature-resistant safety performance of the mobile phone battery. Background technique [0002] With the popularity of communications, mobile phones have become an indispensable item in people's lives, and with the reduction of communication charges, more and more people use mobile phones to talk for a long time, and the phenomenon of mobile phone heating will inevitably exist when the mobile phone is used for a long time , If there is a short circuit in the mobile phone circuit, it will also cause the mobile phone battery to heat up rapidly. There are many types of accidents when the mobile phone battery heats up. The common ones are normal phenomena such as liquid leakage and deformation, but there are also some accidents that may harm the human body such as explosions and splashing liquid. Later change detection is crucial. Con...
