Detailed Description

The present invention will be described in detail with reference to the following embodiments. The following examples will aid those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any way. It should be noted that various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention. All of which belong to the protection scope of the present invention.

As shown in fig. 1 and 2, according to the utility model provides a pair of battery package module end plate and battery module, including end plate body and end plate lid, wherein: the endplate body including a central region and an edge region surrounding the central region; the intermediate region comprises an open cavity structure; the end plate cover is matched with the cavity structure and covers the opening of the cavity structure; one side of the cavity structure is provided with an opening, and a connector for connecting external equipment is installed at the opening; a BMS module is installed in the cavity structure. The end plate body is an aluminum end plate body. The cavity structure is internally used as an aluminum substrate. The edge area is set to be a hollow structure. The left side and the right side of the top of the end plate body are provided with mounting holes, and fillet transition surfaces are arranged between the left side surface and the right side surface of the end plate body and the front side surface of the end plate body. The upper surface of the end plate body is a plane.

The utility model discloses with the BMS design on the end plate, regard the PCB of substrate to the end plate, then welding components and parts. The entire structure of the end plate also becomes the outer case of the BMS. Specifically, the utility model discloses carry out the insulating layer coating in the inside BMS paster region of end plate, paste the copper foil, the pressfitting, the etching, then brush operations such as solder mask, produce the PCB design of BMS paster. Then directly carry out the paster above this, directly cover with the end plate lid after the paster is accomplished, let BMS and end plate become integrative design.

The utility model discloses a set up the end plate of aluminium material as aluminium base board, need not to provide the substrate that is used for the paster again, saved the PCB cost, also alleviateed the weight of whole system more.
