Radiating type flexible package battery module group

Abstract

The invention provides a radiating type flexible package battery module group. The radiating type flexible package battery module group comprises flexible package monomer batteries, radiating aluminum plates, battery connecting pieces, acrylonitrile butadiene styrene (ABS) insulating clamp plates and insulating parts, wherein 1 to 4 mounting holes of which corresponding aperture is 4 to 8 millimeters are formed on each radiating aluminum plate and each ABS insulating clamp plate in directions vertical to the plates; pull rods vertical to the axial direction of the monomer batteries fix the radiating aluminum plates and the ABS insulating clamp plates through the mounting holes; heat-conducting plates are arranged along the arrangement direction of the flexible package monomer batteries and in a direction vertical to the axial direction of the monomer batteries, and are closely attached to hems of the radiating aluminum plates; two heat pipes are arranged at one end of each heat-conducting plate and are connected with a radiator through a guide rail groove. According to the flexible package battery module group, the radiating aluminum plates are adopted for cooling, so that the whole structure can be quickly refrigerated, a good radiating effect is achieved, and the aim of prolonging the service life of a battery is fulfilled.

Description

Technical field: [0001] The invention relates to a battery, in particular to a heat dissipation type soft package battery module group. Background technique: [0002] Most of the existing battery cell structures are a plurality of soft-packaged batteries connected in parallel, and then arranged in a hard insulating casing. The upper part of the casing is provided with a positive terminal and a negative terminal. The positive tabs of the soft-packaged batteries are connected to each other and set on the positive terminal of the casing. The negative tabs of the flexible-packaged batteries are connected to each other and set on the negative terminal of the casing. This battery structure is the basis for designing a battery box. structure and connections. On the one hand, the battery designed in this way makes it difficult to dissipate the heat of the soft-packed battery in the hard shell, and on the other hand, it is difficult to monitor the temperature inside the plastic-seal...

AI Technical Summary

Problems solved by technology

Screws are used to directly connect the battery tabs together, and there is no fixing method. When the battery box vibrates, the connection will be ineffective and a safety accident will occur.

[0007] The battery groups in the prior art are generally fixed with steel plates and long bolts. The steel plates are conductors and non-insulating, and are connected to the battery box, which may easily cause the entire battery box to be electrified and cause short-circuit accidents.

Due to the connection between the batteries, the height of the steel plate is much smaller than the top of the battery, so the data acquisition line of the internal management system of the battery box cannot use the steel plate to form a wire slot, and cannot be fixed, leading to chaos
