Description

Technical Field

[0002] Energy storage connecting cables are cables specially used to connect various components in the power energy storage system, such as battery modules, battery clusters, battery clusters and combiner boxes, and battery clusters and energy storage converters. They are designed to ensure the effective transmission of electric energy and the safe and stable operation of the system. Energy storage connecting cables are widely used in solar photovoltaic power generation systems, wind power generation systems, electric vehicle charging stations and other fields. In these systems, the connecting cables are responsible for the effective transmission of electric energy between battery modules or battery clusters to ensure the normal operation of the system and the efficient use of electric energy.

[0003] At present, when setting up the protection structure of some energy storage connecting wires, only an insulating layer is set on the outside of the wire. The material of the insulating layer is usually polyvinyl chloride, polyethylene or cross-linked polyethylene. Although these materials have certain elasticity, when the connecting wire needs to be bent at a large angle, the insulating layer made of these materials is still damaged or broken. At this time, if the operator accidentally touches the exposed connecting wire, he may suffer electric shock injury, which has certain safety hazards. Therefore, an anti-electric shock energy storage connecting wire is proposed. Utility Model Content
