Abstract

The embodiment of the invention relates to the technical field of electronics, and discloses a battery, a terminal and a battery protection method. The battery comprises a battery core, a battery protection board, a battery shell and a resistance strain sensor. The battery shell covers the battery core and the battery protection board. The battery protection board is electrically connected with the positive electrode lug and the negative electrode lug of the battery core. The battery protection board is provided with a control chip. The resistance strain sensor comprises a sensitive grid and pins led out of the sensitive grid. The sensitive grid is fixed within the area of the battery core. The pins are electrically connected with the control chip on the battery protection board. According to the technical scheme of the invention, the sensitive grid is fixed with the area of the battery core, and the pins are electrically connected with the control chip on the battery protection board. In this way, during the charging process of the battery, the variation of the battery itself can be detected according to the variation of the resistance value. Therefore, the voltage and the current of the battery during the charging process can be reasonably controlled. The over-expansion of the battery is avoided.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a battery, a terminal and a battery protection method. Background technique [0002] With the development of mobile terminals, mobile terminals such as mobile phones and tablet computers have become indispensable tools in life and work. As the function of the mobile terminal becomes more and more powerful, in order to ensure the standby time, the battery capacity of the mobile terminal is also increased, and the charging speed of the battery is also faster and faster. Mobile terminals currently on the market usually optimize battery charging through ordinary circuits, so as to realize fast charging of the battery. [0003] However, in the process of realizing the present invention, the inventor found that there are the following problems in the prior art: through the ordinary circuit to optimize the battery charging, although the battery can be quickly charged, but in the pr...
