Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery pack, in particular to a storage battery pack with uniform cooling system. BACKGROUND

[0002] In actual power storage work, the temperature control of the storage battery is particularly important. In the traditional battery pack, the cooling air flows into the battery box from the front inlet, then flows out from the rear outlet. The cooling air is heated by the working battery cells during the movement, and the convection heat exchange of the battery pack decreases rapidly. The current storage battery pack with uniform cooling system is not convenient to control the uniform cooling of the battery, and the heat dissipation uniformity is poor. At the same time, the battery protection effect is poor. A large amount of condensed water is generated during air conditioning cooling work, which usually needs to be protected by an aluminum protective shell while ensuring heat dissipation. However, the aluminum protective shell soaked for a long time is prone to sand leakage, which is not convenient to use tail gas for leakage protection. At the same time, the terminal of the traditional battery pack is usually directly welded with copper bar, and the terminal is prone to loose connection when the battery swells, which may cause hidden troubles such as loose connection. In order to ensure the stability of the battery pack transportation and other work, the battery cell is usually fixed, and once the local battery cell swells, it is easy to cause extrusion damage to the surrounding battery cells, which may expand the safety hidden trouble, and it is not convenient to automatically control the compensation of the swelling distance.
