Description

Technical Field

[0001] The utility model relates to the technical field of soft-pack batteries, in particular to a soft-pack battery module with high stability. Background Art

[0002] A soft-pack battery module is composed of multiple soft-pack cells. At present, the application of soft-pack cells mainly considers stacking the cells or gluing and fixing the cells. With the rapid development of new energy technologies, soft-pack cells are widely used due to their high energy density, flexible design, and high safety. At present, the outside of the soft-pack cell is usually covered with an aluminum-plastic film. During the charge and discharge process of the soft-pack cell, the active substance inside the soft-pack cell reacts with the electrolyte, causing the internal pressure of the soft-pack cell to increase, and the aluminum-plastic film expands and ruptures to release the internal pressure.

[0003] The aluminum-plastic film on the outside of the soft-pack battery cell is a flexible material. Therefore, the direction of expansion and pressure relief of the soft-pack battery cell is random, the direction of heat spread is uncertain, and it is easy to cause adjacent soft-pack battery cells to be ignited;

[0004] Secondly, when the soft-pack battery cell bulges, the staff cannot find it in time. The battery cell that has not been replaced is prone to excessive heat after use, and it is easy to spontaneously combust after the heat accumulates, which poses a safety hazard. Utility Model Content

[0015] Optionally, springs are fixedly installed at equal distances on the outside of the inner shell, and a limit rod is fixedly installed inside the spring;

[0016] The spring is used to position baffle one and baffle two. When a bulge appears on the battery cell body, baffle one or baffle two will be pushed to move, causing the inner shell to be misaligned, thereby reminding the user that there is a problem with the soft-pack battery.

[0017] Optionally, an anti-slip sheet is fixedly installed on the outer side of the spring, and the anti-slip sheet is circular in shape, and a sensor is fixedly installed on the anti-slip sheet, and the sensor is electrically connected to the buzzer;
