Description

Technical Field

[0001] This utility model relates to the field of battery wiring harness technology, specifically a battery pack cell wiring harness assembly. Background Technology

[0002] The automotive industry has become a pillar industry in my country, with new energy vehicles being a crucial component. New energy vehicles utilize battery packs installed within the vehicle, operating on electricity to power the battery, making them more energy-efficient and environmentally friendly, aligning with national environmental policies. However, current battery packs primarily consist of individual batteries connected to connector assemblies via cables. To maintain a neat internal structure and facilitate future maintenance, the cables are typically bundled into harnesses and guided. Existing harness assemblies have many sharp edges, especially when guiding the cables, as the cable sheaths are often located at these edges, easily leading to damage. Current harnesses are mainly secured with tape, but the significant heat generated during battery operation reduces the tape's adhesiveness. Utility Model Content

[0003] The purpose of this invention is to provide a battery pack cell harness assembly to solve the problems mentioned in the background art.
