Description

Technical Field

[0001] This utility model relates to the field of battery end plate technology, specifically to the extrusion structure of battery end plates for new energy vehicles. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.

[0003] With the rapid development of new energy vehicles, power batteries, as one of their core components, have also received widespread attention and research. Power batteries are typically composed of multiple cells, which expand during charging and discharging, mainly due to internal pressure changes caused by electrochemical reactions. If effective measures are not taken to address this expansion, it may adversely affect the safety and lifespan of the battery pack. Traditional end plates often lack structures to prevent the continuous swelling of the battery from causing compression on the end plates. Therefore, this paper proposes an end plate compression structure for new energy vehicle batteries. Utility Model Content

Alternatively, a cross-shaped screwdriver can be used. During adjustment, a flathead or cross-shaped screwdriver is inserted into the adjustment slot 401, and the screwdriver is rotated to rotate the adjustment plate 4. This causes the adjustment plate 4 to change position relative to the threaded hole 101, thus achieving the adjustment effect. A groove 403 is provided on one side of the connecting spring 302 of the adjustment plate 4. A buffer space 2 is provided on one side of the end plate body 1, and a buffer assembly 3 is installed in the buffer space 2.
