Embodiment Construction

[0045] The invention provides a battery, a mobile terminal and a method for automatically breaking the circuit of a large current. When it is detected that the battery outputs a large current that may cause a short circuit, the connection between the battery and the main board of the mobile terminal is disconnected, and the mobile terminal is powered off to protect the battery and the main board. , It has played an effective preventive measure against the short circuit of the battery. And when starting up next time, after detecting the short circuit is removed, it will automatically identify whether the last power outage was caused by a short circuit or a normal shutdown operation, thereby prompting the user for the reason why the mobile terminal is abnormal. In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings a...

Abstract

The invention discloses a battery, a mobile terminal and a large-current automatic cutout method therefor. The mobile terminal comprises a main board and the battery; when the battery detects current exceeding a preset threshold, the battery cuts off of power supply to enable the main board to shutdowns, so that the battery and the main board are protected, and effective preventive measures on short circuits of the battery are realized; the battery restores to supply power after the first preset time to ensure normal starting up next time; the main board detects whether the battery outputs voltage sequence or not in starting up, if so, the main board judges whether the obtained voltage sequence is the same as a pre-stored sequence or not, if so, the main board prompts a user that the shutdown of last time is abnormal, so that the abnormal condition of the mobile terminal can be prompted.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a battery, a mobile terminal and a large current automatic circuit breaking method thereof. Background technique [0002] The battery is the main power supply part of the mobile terminal, which accumulates a large amount of electric energy; in the actual use of the mobile terminal, the following situations may occur: [0003] 1. When some conductive objects of the user (such as hand sweat and keys) come into contact with some exposed parts in the mobile terminal (such as earphone socket, charging port), it will short-circuit the main board of the mobile terminal. [0004] 2. Some conductive materials inside the mobile terminal fall off due to external force (such as falling), thus short-circuiting the main board of the mobile terminal. [0005] Under the above circumstances, the battery will output a very large current to make the battery circuit. The high current may d...
