Problems solved by technology

When the temperature is too high or the temperature is too low, the activity of lithium ions will deteriorate
As a result, when charging at low temperature, the capacity of the lithium battery will decrease and the charging time will be longer. When charging at high temperature, the life of the lithium battery will be shortened, and the charging time will be shortened

Abstract

The invention discloses a charging temperature adjusting device and a mobile terminal; the charging temperature adjusting device comprises a semiconductor assembly and a selector switch; the semiconductor assembly is connected with a battery; when the battery temperature is lower than a first temperature threshold, the selector switch controls the semiconductor assembly to heat up the battery; when the battery temperature is higher than a second temperature threshold, the selector switch controls the semiconductor assembly to cool down the battery. The charging temperature adjusting device can control the lithium battery temperature in a preset temperature scope, thus ensuring lithium ion motion activity to be in a good state in electrolyte, improving charging efficiency, and protecting the battery hardware performance.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to the field of mobile terminals, and in particular to a charging temperature adjustment device and a mobile terminal. Background technique [0002] With the development of terminal technology, users can not only use mobile terminals for traditional applications, such as using mobile phones to answer or make calls, but at the same time, users can also use mobile terminals for video playback, audio playback, web browsing, taking pictures, navigation, and playing games, etc. application. [0003] As the frequency of use of mobile terminals increases, mobile terminals need to be charged frequently to meet the needs of users. Currently, most mobile terminals use lithium batteries. The charging principle of a lithium battery is that when the battery is charged, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move to the negati...
