Which charging cable should I choose?

All Voldt® charging cables include a 3-year full warranty and 100 days of hassle-free returns. We stand behind the quality of our European-made products, which are tested to meet the highest standards of safety and durability. Every cable is built to last. If something isn’t right, we’ll make it right: whether that means a quick replacement, repair, or return. It’s our way of ensuring you can charge with complete confidence, every time.

No noticeable power loss, even with longer cables

No, Voldt charging cables do not experience any significant power loss due to their length. Voldt uses only high-quality copper conductors with low resistance, ensuring that even longer cables (such as 10 or 15 metres) can efficiently transmit current without noticeable voltage drop. The cables are designed according to international standards (such as IEC 61851 and IEC 62196), which specify maximum allowable voltage drop and heat development, so charging performance remains optimal.

Optimal conductor size prevents voltage drop

In theory, longer charging cables could lead to some power loss, particularly if the cable has a thin conductor or is made from lower-quality materials. Voldt prevents this by using conductors with appropriate cross-sectional area depending on the cable’s maximum current rating (e.g. 6 mm² for 32A 3-phase cables). This keeps voltage drop to negligible levels—typically less than 1%—which is well within regulatory limits. This is crucial for both safety and charging efficiency.

Tested for performance and safety

Finally, all Voldt cables are rigorously tested for electrical performance, temperature rise, and reliability under load. Customers can trust that even a 15-metre cable performs just as well as a shorter one. This makes Voldt cables ideal for situations where the charging point is further away from the vehicle, without compromising on speed or safety.

Temperature protection in EV charging cables is a built-in safety feature that automatically prevents overheating during the charging process. It continuously monitors the temperature at critical contact points—typically in the plug or control box—and interrupts or limits power flow if the temperature exceeds a safe threshold. This is essential to prevent damage to the cable, plug, vehicle inlet, or household socket, especially when charging at higher currents such as 16A or 32A.

How it works technically

In Voldt® charging cables with temperature protection, integrated sensors—often thermistors or thermal fuses—are positioned near the plug contacts and control circuitry. These sensors communicate with the control unit (IC-CPD in Mode 2 chargers, or the car's onboard system in Mode 3) to regulate or stop the current when a critical temperature is reached, usually between 70°C and 90°C depending on the component. For example, Voldt®’s mobile charging cable includes this feature in the plug housing to protect household sockets, which are less robust than dedicated charging stations.

Why temperature protection is crucial for safety and durability

Overheating is one of the leading causes of EV charging malfunctions and fire hazards, especially with cheaper cables lacking certification. Long charging sessions, poorly ventilated areas, or worn-out sockets can all lead to heat buildup. With temperature protection, the cable can proactively detect unsafe conditions and shut down charging before any damage occurs. This not only enhances user safety but also extends the lifespan of both the cable and the vehicle’s charging inlet.

Voldt® cables with built-in thermal protection

All Voldt® mobile chargers are equipped with advanced temperature monitoring, CE and TÜV certified for reliability. This makes them suitable even for older or less stable socket installations. In addition, Voldt®’s robust plug designs—crafted with European-grade materials—are engineered for excellent thermal conductivity and heat dissipation, further enhancing safety during daily use. When choosing a charging cable, always verify the presence of temperature protection for peace of mind and long-term performance.
