Problems solved by technology

[0002] The pouch battery will swell after being used to a certain extent. With the increase of the usage time of the pouch battery, it is easy to be abused and exceed the service life of the pouch battery, which will cause the pouch battery to swell. When the amplitude exceeds the expansion threshold and continues to be used, the performance parameters of the pouch battery will drop sharply, and it will easily cause safety problems such as combustion and explosion, causing casualties
[0003] However, even though the use risk of pouch batteries exceeding the expansion threshold is so great, the existing technology still lacks an effective method for effectively detecting whether the expansion of pouch batteries exceeds the expansion threshold, even if there is a method for detecting the expansion of pouch batteries , its structure is relatively complicated, and its implementation cost is relatively high, so it cannot be promoted in different industries

Embodiment Construction

[0031] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0032] refer to figure 1 The pouch battery expansion detection system 1000 of this embodiment includes a pouch battery expansion detection device 100 and a battery management system. The battery management system is a system for obtaining various performance parameters of the battery, controlling battery on-off, and daily maintenance of the battery. . The pouch battery expansion detection device 100 is electrically connected to the battery management system. The pouch battery expansion detection device 100 detects whether the expansion of the battery 2 exceeds a predetermined threshold and generates an expansion signal, and transmits the expansion signal to the battery management system. The expansion signal selectively connects or discon...

Abstract

The invention discloses a soft package battery expansion detection device, which is suitable for carrying out expansion detection on a battery in the battery compartment. A gap is formed between the inner wall of the battery compartment and the outer wall of the battery, the soft package battery expansion detection device is installed in the gap, and when the battery expands and the soft package battery expansion detection device is triggered, the soft package battery expansion detection device generates an expansion signal; the soft package battery expansion detection device is simple in structure and low in implementation cost, can effectively detect the expansion of the battery, and avoids safety accidents caused by the expansion of the battery. The invention also discloses a soft package battery expansion detection system. The invention also discloses a soft package battery expansion detection method.

Description

technical field [0001] The invention relates to the field of battery expansion detection, in particular to a pouch battery expansion detection device, system and method. Background technique [0002] The pouch battery will swell after being used to a certain extent. With the increase of the usage time of the pouch battery, it is easy to be abused and exceed the service life of the pouch battery, which will cause the pouch battery to swell. When the amplitude exceeds the expansion threshold and continues to be used, the performance parameters of the pouch battery will drop sharply, and it will easily cause safety problems such as combustion and explosion, resulting in casualties. [0003] However, even though the use risk of pouch batteries exceeding the expansion threshold is so great, the existing technology still lacks an effective method for effectively detecting whether the expansion of pouch batteries exceeds the expansion threshold, even if there is a method for detect...
