The Difference between Coiled and Straight EV Cables

May 22, 2023

Consider taking a cross-country road trip in your sleek, futuristic EV. You're driving along, knowing you may recharge your vehicle's battery and resume cruising anytime. This unusual sensation of independence and peace of mind is made possible by the outstanding EV charging cables that easily link your vehicle to a nearby charging station.

The coiled and straight cables dominate the enormous terrain of EV cables. Each cable type has distinct qualities and benefits, responding to EV owners' global demands and preferences.

This post will examine the differences between coiled and straight EV cables and explain why straight cables are the best option for EV owners.

Understanding Coiled EV Cables

Coiled-shaped electric car charging cables have a spiral coil design, improving operation flexibility and maneuverability. The spiral form also protects the internal copper conductor, increasing its endurance and longevity. Coiled cables thrive when a shorter cable length is needed since they stretch and recoil readily.

Unveiling Straight EV Cables

On the contrary, linear electric vehicle (EV) cables exhibit a sleek design and typically possess greater length. Meticulously crafted to cater to various charging requirements, these cables have commendable durability and encompass safety attributes such as minimal resistance and voltage drop. Furthermore, their streamlined configuration facilitates proficient heat dissipation, eases the handling, and mitigates the potential for overheating during the charging process.

· Super handy cables for conveniently charging your EV in the garage or driveway.

· Public areas, parking lots, and commercial establishments can now offer the convenience of straight cables for easy EV charging.

· Straight cables are compatible with various charging stations, ensuring a seamless charging experience for EV owners in different locations.

These cables are an expert's choice to fill your EV's thirsty battery in any circumstances and weather conditions.

Comparing Coiled and Straight EV Cables

Tensile Strength and Compression Resistance

Straight EV cables inherently possess superior tensile strength compared to coiled cables, allowing them to endure significant pulling force without succumbing to breakage or excessive stretching. This inherent durability makes them highly reliable even in demanding charging scenarios.

Furthermore, straight EV cables are engineered to exhibit remarkable resistance against compression forces. This crucial attribute safeguards the cable's internal components and preserves the integrity of transmitted electrical signals. 

The ability to withstand compression becomes particularly valuable when the cables encounter substantial pressure from heavy loads or unforeseen impacts.

Working length limitation in Coiled cables

The physical attributes of coiled cables impose limitations on their effective working length. 

· A spiral structure necessitates more material and occupies extra space compared to straight cables of the same distance.

· Coiled cables become bulkier and heavier, making them more challenging to handle and operate.

Coiled cables require a substantially greater length to span the same distance (from the EV charger to the car). For instance, a 5-meter span would need an approximately 8-meter coiled ev charging cable. This additional length can prove burdensome, demanding more workload and resulting in an uneasy job.

Storage and Cable Management Challenges

An additional factor worthy of consideration is the inherent nature of coiled cables. The coiling process introduces a series of loops along the cable's length, which are instrumental in facilitating. However, these loops can pose a challenge when it comes to storage. Unlike straight cables, where one has greater control over manipulating the loops, the number of coils in a coiled cable remains fixed.

Consequently, coiled cables naturally occupy a more significant amount of space. In compact areas such as the trunk of a car, where space is at a premium, accommodating the extended length of a coiled cable can present difficulties.

Impact on Charging Speed and Time

It is worth emphasizing that straight cables offer a clear advantage when minimizing voltage drops, consequently enhancing charging efficiency and expediting the overall charging process.

This efficiency stems from their ability to transmit power effectively, reducing voltage drop and enabling electricity to flow more directly from the power source to the EV battery. The outcome is a significantly accelerated charging speed, facilitating swift recharging of renowned electric vehicle models like Tesla, BMW i3, or Audi e-Tron, beating down the performance achieved with coiled cables.

Safety Considerations and Risks

Due to their elevated positioning, coiled cables reduce trip hazards and improve visibility during the charging process. In contrast, straight cables necessitate careful positioning to mitigate potential risks, but when managed correctly, they offer entirely safe and risk-free charging. 

Costing & affordability

The cost of straight EV cables and coiled EV cables can differ based on factors like the manufacturer, cable length, materials used, and additional features. 

Generally, straight EV cables tend to be more budget-friendly when compared to coiled EV cables.

In 2023, evcome will present a cost-effective, affordable straight EV charger cable with excellent specifications. With a length of 5 meters, a rating of 220V 16A, and certification from IEC 62196, CE, UKCA, and ROHS, we ensure strict adherence to safety and quality standards.

Risk of Overheating and Cable Wear

Coiled cables have a greater chance of generating heat during the charging process. The coiling configuration limits the airflow around the ev charging cable, impeding effective heat dissipation. Excessive heat can degrade the cable's insulation and impact its overall performance and longevity.

On the other hand, Evcome's straight cables exhibit superior heat dissipation properties, mitigating the risk of overheating and minimizing cable wear during charging sessions. Heat dissipation not only enhances safety but also extends the lifespan of the cable, ensuring long-lasting reliability.

Are Straight Cables More Durable than Coiled Cables? 

Of course! Straight EV cables offer superior durability to coiled cables, owing to their robust linear construction.

The sturdy linear design of straight cables enables them to withstand the demanding conditions of regular use. This design minimizes the risk of kinking, bending, or tangling, which can potentially cause damage to the internal conductor or insulation. The exceptional durability of straight cables ensures their ability to endure multiple charging sessions and maintain reliable performance even after prolonged use.

Conversely, coiled cables inherently possess certain limitations in terms of durability. The coiling process introduces stress points, particularly at the bends and twists created during coiling. These stress points render the cable more susceptible to wear and tear, such as wire breakage or insulation damage, which can eventually impair its performance and lifespan.

Are Straight Cables Compatible with All Charging Stations? 

Straight cables are designed to be compatible with most electric vehicle (EV) charging stations, thanks to their standardized connectors and electrical specifications. The compatibility primarily relies on the type of connector employed on the ev charging cable and the interface of the charging station.

In homes and public charging points, users widely utilize straight cables with Type 1 (SAE J1772) or Type 2 (IEC 62196) connectors for AC charging stations. These connectors adhere to industry standards, and manufacturers engineer them specifically to facilitate proper electrical connections and ensure safe charging.

Should I go for a coiled or Straight EV charging cable?

Opting for straight EV cables, particularly those offered by "EVCOME," is advisable for the best quality. Our straight cables provide superior durability, minimized voltage drops, efficient heat dissipation, and compatibility with various EV charging stations.
