Embodiment 1

[0022] figure 1 It is a flowchart of a method for detecting battery abnormality in a dual-battery product according to an embodiment of the present invention, such as figure 1 shown,

[0023] In step S110, the current voltage of the dual-battery product is detected, and when the detected current voltage is within a preset voltage range, the detection duration is determined according to the current voltage, and charging detection is started for the dual-battery product.

[0024] In step S120, within the determined detection period, the voltage of the dual-battery product being charged is detected multiple times, and the detected voltage value and the corresponding charging period are recorded each time.

[0025] In step S130, a linear curve is fitted according to the multiple sets of records of the voltage value and the charging duration, and whether there is a single battery abnormality in the dual-battery product is detected according to the slope of the fitted linear curve....

Embodiment 2

[0064] Figure 7 It is a schematic structural diagram of a device for detecting battery abnormality in a dual-battery product according to an embodiment of the present invention, such as Figure 7 As shown, the apparatus 700 includes a memory 720 and a processor 710. The memory 720 stores a computer program that can be executed by the processor 710. When the computer program is executed by the processor 710, the computer program can realize the following: figure 1 method steps shown.

[0065] The memory 720 and the processor 710 are communicatively connected through an internal bus 730. In one embodiment of the present invention, the memory 720 stores a computer program 721 for detecting battery abnormality of a dual-battery product.

[0066] In various embodiments, memory 720 may be memory or non-volatile memory. The non-volatile memory may be: a storage drive (eg, a hard disk drive), a solid-state disk, any type of storage disk (eg, an optical disc, a DVD, etc.), or a simi...

Abstract

The invention discloses a method and device for detecting the battery abnormality of a double-battery product. The method comprises the steps: detecting a current voltage of the double-battery product, determining the time duration according to the current voltage when the current voltage is detected to be within a preset voltage section, and starting the charging detection of the double-battery product; carrying out the detection of the voltage of the double-battery product in charging for many times in the determined detection time duration, and recording the voltage value detected at each time and a corresponding charging time duration; carrying out the fitting of one linear curve according to multiple groups of records of voltage values and the charging durations, and detecting whetherthe double-battery product has a single-battery abnormality or not according to the slope of the fitting linear curve. Compared with the prior art, the method and device can achieve the intelligent detection of the battery abnormality of the double-battery product without an additional battery voltage management and control chip, effectively eliminate the hidden safety troubles caused by a condition that the battery abnormality is not timely found, saves the overall space of a circuit control board, reduces the production cost, and improves the user experience.

Description

technical field [0001] The invention relates to the field of battery detection, in particular to a method and a device for detecting abnormality of a battery in a dual-battery product. Background technique [0002] The Bluetooth headset uses wireless transmission for data transmission, which eliminates the shackles of wires and greatly improves the convenience of use. After years of development, Bluetooth headsets have become a popular element in headset products and are well received by users. Among the current Bluetooth headset products, the most popular trend is sports characteristics, that is, lightweight, comfortable to wear, anti-shedding, waterproof and sweat-proof, and it is best to have a variety of sensors such as heart rate detection to monitor the user's physical function. [0003] In order to achieve the goal of wearing light, sports Bluetooth headsets mostly use thin wires to connect the wire control box and binaural earplugs. If the wire control box method is...
