Explosion-proof and flame-retardant structure of lithium battery based on internal temperature measurement

Abstract

The invention discloses an explosion-proof flame-retardant structure of a lithium battery based on internal temperature measurement, which comprises a box body, a cover body buckled and connected with the box body, and a controller connected to the side wall of the box body, the bottom surface of the inner cavity of the box body is connected with a plurality of semiconductor chilling plates, and the box body is connected with a copper body below the semiconductor chilling plates. A plurality of copper columns are connected to the front side wall and the left side wall of the box body, external radiators are connected to the positions, corresponding to the copper columns, of the front side wall and the left side wall of the box body, a first temperature sensor and a second temperature sensor are installed in the box body, and two stepped clamping blocks are placed in the box body; two locking columns are connected to the upper portion of the cover body, and an electric control superfine dry powder fire extinguisher is connected to the upper portion of the cover body. The stepped clamping block is provided with a plurality of stepped notches with different gradients, the stepped clamping block is provided with a plurality of storage cavities with upward openings, and a plurality of gaskets with different widths and lengths are placed in the storage cavities.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof and flame-retardant structures of lithium batteries, and in particular relates to an explosion-proof and flame-retardant structure of lithium batteries based on internal temperature measurement. Background technique [0002] Lithium batteries are a type of batteries that use lithium metal or lithium alloys as positive / negative electrode materials and use non-aqueous electrolyte solutions. [0003] In order to reduce the impact of the external environment, lithium battery packs are usually placed in a relatively closed environment. These conditions of use will cause a large amount of heat generated by the lithium battery pack during work, which cannot be discharged smoothly and quickly, resulting in a sharp rise in the temperature of the lithium battery. Working at a higher temperature for a long time will shorten the battery life and reduce the battery life. Performance; the long-term une...

AI Technical Summary

Problems solved by technology

[0005] 1. The internal lithium battery pack L cannot be cooled efficiently and quickly;

[0006] 2. Unable to adapt to lithium battery packs L of different sizes and hold them stably;

[0007] 3. It cannot automatically monitor the temperature in a closed environment and perform automatic cooling treatment. When the temperature rises abnormally and causes the lithium battery pack L to spontaneously ignite, there is no automatic extinguishing facility, which further expands the danger
