Embodiment Construction

[0065] In the battery detection method of the embodiment of the present invention, the value of a judgment parameter is obtained in real time during the charging process, and the current value of the judgment parameter is compared with the standard value to judge whether there is a battery cell disconnection, thereby improving the safety of the battery .

[0066] Here, first of all, the safety hazards caused by the open circuit of the battery are explained as follows.

[0067] For a series and multi-parallel battery structure, there are multiple parallel cells, and some cells in the multiple parallel cells are disconnected, which will not cause the entire battery to be disconnected. The entire battery can still complete the power supply and Discharge.

[0068] However, for battery charging, it has a safety threshold of charging current. If the charging current of a single cell is too high, it will not only lead to a reduction in battery life, but in more serious cases, the rechargea...

Abstract

The invention aims at providing a battery detecting method, a battery and an electronic device and improving the battery safety. The battery comprises multiple parallelly-connected battery cells. The battery detecting method comprises the steps of charging the battery; obtaining a current value for judging diameters of the battery; obtaining a standard value for judging the diameters; obtaining a comparison value of the current value judging the diameters and the standard value for judging the diameters; and confirming that disconnected battery cells exist in the battery when the comparison value meets a predetermined condition. The safety of the battery in use is improved.

Description

Technical field [0001] The invention belongs to the field of electronics, and particularly relates to a battery detection method, a battery and an electronic device. Background technique [0002] With the continuous advancement of electronic technology, more and more electronic devices are moving in the direction of portability, such as mobile phones, notebook computers, tablet computers, etc., which are all portable electronic devices. [0003] And portable electronic devices have a way to use rechargeable batteries to supply power. [0004] The current rechargeable batteries are divided into multiple methods. Among them, in order to improve the battery life, the single-string multiple-parallel method has become the basic structure of the battery of many electronic devices. [0005] However, the prior art does not provide how to detect the battery working condition of a single-string and multiple-parallel battery, and cannot guarantee the safe operation of the battery. Summary of th...
