[0009] Preferably, a fixing protrusion for positioning the aluminum bar is provided inside the groove.

[0010] Preferably, a plurality of through holes are provided in the middle of the blister tray.

[0011] Preferably, a cable tie for fixing the wire harness passes through the interior of the plurality of through holes.

[0012] Preferably, a blister cover is provided on the top of the blister tray, and the blister cover and the blister tray are clamped with each other.

[0013] Preferably, a steel belt is fixed to the outer sides of the plurality of battery modules.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Using wiring harnesses instead of PCB boards reduces the welding process on the information collection line, reduces the occurrence of poor soldering quality problems, and reduces after-sales costs.

[0016] 2. Use blister trays, which have low mold opening costs and low unit prices, thus greatly reducing costs.

[0017] 3. The wiring harness and aluminum bar are fixed on the blister tray to form a whole. When the module is laser welded, it can be directly placed on the stacked modules, and the screws are locked at both ends for welding. There is no need to add tooling to fix the aluminum bar and wiring harness, which simplifies the processing technology.

[0018] 4. The insulation cover is made of blister cover, which is snapped together with the blister plate, which is both beautiful and ensures the insulation effect. BRIEF DESCRIPTION OF THE DRAWINGS
