Although choosing an electric car charging cable may seem like a detail, it is actually one of the most important decisions to ensure safety, compatibility and efficiency during charging.
The wallbox charging cable is an essential component of the entire ecosystem of any electric vehicle that has specific requirements in terms of power, connector type, and mode of use. Navigating through the various models available may not be easy.
In this guide to choosing an electric vehicle charging cable, we look in detail at the different types of connectors, the differences between single-phase and three-phase cables, and the main criteria for making an informed choice, especially in light of the latest European regulations and standards.
TL;DR Are you in a hurry? What to know now to choose wallbox charging cable
Connector type. Today 99% of electric cars have the Type 2 plug. If yours is different, you most likely have an obsolete model.
Single-phase or three-phase? If your car only charges in single-phase, a three-phase cable is not needed for now, but it may make sense if you plan to change cars.
How long should it be?
5 meters = good for almost anything
7meters = more suitable and safe if the socket is far away
Safety. The cable must be CE-certified and IEC 62196-compliant, equipped with DC leakage detector and IP55 or higher degree of protection-essential requirements to ensure its safety and avoid overheating, blackouts and damage to the system.

Connector types: what changes
Connector Type 1
Electric vehicle charging cables with Type 1 Connector are the original standard for American and Asian electric vehicles. It is rare in Europe today, but still found on some pre-2020 models. It supports only single-phase AC charging up to 7.4 kW.
Type 2 connector
The Type 2 Connector is the standard European connector for AC (alternating current) charging of electric vehicles. Found on almost all electric and plug-in hybrid vehicles sold in Europe, it is compatible with wallboxes and public charging stations. It can handle recharges from 3.7 kW up to 22 kW, depending on whether it is used in single-phase or three-phase.
CCS Combo 2
CCS Combo 2 is the most widely used system for rapid direct current (DC) charging. It combines a Type 2 cable connector with two additional pins for high-power delivery. It is integrated into fast and ultrafast stations; it does not affect portable cables.
CHAdeMO
CHAdeMO is the Japanese standard for DC wallbox charging. Today it is being discontinued in Europe, but still present on some Asian models. It requires dedicated charging stations with integrated cable.
Car charging cable: single-phase or three-phase
The distinction between single-phase and three-phase cable is crucial in the configuration of the car charging system, as it affects the power that can actually be transferred to the vehicle. The choice between single-phase and three-phase cable depends on two key factors: the compatibility of the vehicle’s on-board charger and the characteristics of the available electrical infrastructure.
- the Single-phase Cable allows charging up to 7.4 kW (32A, 230V) and is the most popular solution in residential settings, where single-phase electrical supplies are the norm.
- the Three-Phase Cable allows power up to 22 kW (32A, 400V), but can only be fully utilized when there is a compatible on-board charger and a wallbox charging point connected to a three-phase grid.
Does it make sense to buy a three-phase cable if the car only supports single-phase?
No, the use of a three-phase cable on a vehicle equipped only with a single-phase charger does not bring any advantage in terms of charging speed: the power will still be limited by the limitations of the car. Therefore, in this case, a three-phase cable is a strategic choice only in anticipation of the future purchase of a vehicle with superior features.
What is the ideal length of electric car charging cable?
The length of the car charging cable is of paramount importance. The choice of length affects the weight and manageability of the cable: a long cable is more versatile, but also bulkier.
The choice of charging cable length should take into account the actual distance between the charging point and the vehicle socket, the layout of the space, and the frequency of use in uncontrolled settings, such as public parking lots or shared areas.
The most common sizes of electric car charging cables
- 5 meters: this is the standard length, most widely used in the market. It represents a good compromise between versatility and maneuverability, being suitable for most residential installations and public columns.
- 7 meters: recommended when the location of the outlet on the vehicle is far from the charging point, or when charging often in public spaces where physical layout control may be lacking. The extra length can make a real difference in awkward situations.
- 3 meters: suitable only for extremely controlled environments, such as private garages where the wallbox is installed close to the car socket. It is unsuitable for dynamic or outdoor settings.
EV charging cable safety and certifications: the real difference
In the context of electric mobility, the quality of the charging cable should not be evaluated solely by the power supported or the length. What really makes the difference are the construction features and certified safety levels, which determine the reliability of the product over time and its suitability for everyday use, even in complex environmental conditions.
Certifications and regulatory compliance electric car cable
A home charging cable is reliable if it is certified according to European standards, starting with the CE marking, which certifies compliance with EU directives on electrical safety, electromagnetic compatibility and materials.
In addition, it is critical that the cable complies with IEC (International Electrotechnical Commission) standards, which specifically regulate home electric vehicle charging equipment, such as IEC 62196 for connectors and sockets.
Integrated safety devices
An often overlooked but technically crucial element is the presence of a direct current (DC) leakage detection system. This is an advanced protection required by the regulations to detect any fault currents originating from the electric vehicle, preventing them from damaging the system or compromising user safety. This function is essential for the proper operation of wallboxes and public columns in mode 3.
IP rating
The electric vehicle charging cable must have an IP55 rating or higher, a parameter that ensures resistance to external agents such as dust, splashing water and moisture. This feature is especially important for use in outdoor environments, public parking lots and uncovered areas, where the cable may be exposed to rain, mud or adverse weather conditions.
Thermal and mechanical resistance
The materials used in the construction of the EV charging cable must offer high resistance to heat and mechanical wear and tear. Indeed, during prolonged charging cycles-especially when performed at high power-the cable can reach significant temperatures. A low-quality sheath can warp, crack or degrade rapidly. The best cables employ industrial-grade rubbers and elastomeric materials designed to maintain insulating and structural properties over time.
Ergonomics and robustness of connections
The ergonomics of the connector directly affect the ease of daily use. A neat design with a non-slip grip and reinforced fittings, makes the cable more convenient to insert and disconnect even in cold or rainy conditions. In addition, the joints between connector and cable are the most mechanically critical point: they must be designed to resist repeated bending, twisting and accidental pulling, ensuring thousands of cycles without deterioration.
