Linear vs. Coiled EV Charging Cables: Why are Linear Cables the Better Choice?

Overview of the Two Cable Structures

Coiled EV cables have a spiral appearance that provides good stretch and flexibility. Its construction helps to alleviate cable tangling and knotting problems, while improving abrasion resistance and longevity. Commonly used in space-constrained or heavy-use environments, this type of cable is suitable for temporary stretching and rapid retraction.

Straight EV cables, on the other hand, have a clean, smooth linear design and are commonly used in a variety of charging scenarios, including domestic garages, commercial charging posts and public spaces. They excel in actual charging efficiency, safety and heat management, making them one of the most popular cable types today.

Comparative analysis of performance

1. Stronger tensile and compression resistance

The linear cable has a sturdy structure with higher tensile strength, able to withstand frequent pulling and dragging without breaking. At the same time, the linear design gives it excellent resistance to compression, even if the external pressure can effectively protect the internal conductor to avoid signal interruption.

2. Higher Charging Efficiency, More Direct Energy Transfer

The linear cable significantly reduces voltage loss, allowing for more efficient transfer of power to the vehicle's battery and increasing the overall charging speed. This is especially important for fast charging scenarios, which can help users save waiting time.

3. Better Heat Dissipation and Reduced Risk of Overheating

Due to their more open structure, straight cables have a greater ability to dissipate heat during use, which helps to minimize overheating of the cables, thus prolonging their lifespan and improving charging safety.

4. Easier handling and storage

Compared to coiled cables, straight cables are simpler to store and route. Especially in the trunk, garage and other areas with limited space, its regular shape can save more space, not easy to knot, easy to daily maintenance and management.

Limitations of coiled cables

Although coiled cables offer some flexibility, there are limitations in the following aspects:

Short effective use length: longer cables are needed for the same span;

Difficulty in storage: the spiral structure takes up more space when coiled;

Poor heat dissipation: it is easy for heat to build up during a long period of time charging, which affects the performance.

Compatibility and Safety

NexwayEV's linear cables are widely compatible with Type 1 (SAE J1772) and Type 2 (IEC 62196) interface standards available on the market, and are suitable for most domestic and public charging facilities. In addition, these cables have passed IEC 62196, CE, UKCA, RoHS and other international certifications to ensure safety, environmental protection and compliance with regional market requirements.
