Problems solved by technology

[0003] The existing method of monitoring the battery temperature is usually to mount a flexible circuit board with a thermistor welded on the battery. However, since the thermistor and the flexible circuit board all require a certain height, the volume of the existing electronic equipment will increase. Larger, not conducive to the development of thinner and lighter electronic equipment

Abstract

The embodiment of the present invention discloses an electronic device and a method for detecting the surface temperature of a battery. The electronic device includes: a battery body structure; a metal layer located on the surface of the battery body structure, and the metal layer includes a first metal region and a second metal region. A metal area, the thermocouple characteristics of the first metal area and the second metal area are different; a processor electrically connected to the metal layer, used for according to the first metal area and the second metal area The potential difference obtains the temperature of the surface of the battery body structure, so that the first metal region and the second metal region with different thermocouple characteristics in the metal layer located on the surface of the battery body structure can be directly used to monitor the temperature of the surface of the battery body structure without Furthermore, a flexible circuit board and a heat-sensitive element are additionally arranged to reduce the volume of the electronic device while monitoring the temperature of the battery, which is beneficial to the development of thinner and lighter electronic devices.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an electronic equipment and a method for detecting the surface temperature of a battery thereof. Background technique [0002] With the continuous increase of the battery capacity of electronic equipment, its charging current is also increasing, which leads to more and more heating of the battery during the charging process of the existing mobile phone. Therefore, accurately monitoring the battery temperature to ensure the safety of electronic equipment has become a technical problem to be solved urgently by those skilled in the art. [0003] The existing method of monitoring the battery temperature is usually to mount a flexible circuit board with a thermistor welded on the battery. However, since the thermistor and the flexible circuit board all require a certain height, the volume of the existing electronic equipment will increase. Larger size is not conducive to...
