Anyone who drives an electric car will sooner or later be asked this question: Which charging cable do I need? The choice seems simple, but it is surprisingly technical. If you choose the wrong cable, you charge too slowly, your charging point doesn't work, or worse: you damage the system.
In this article, we explain exactly:
-
Which charging cables there are
-
What your car supports (Type 1 or Type 2, 1-phase or 3-phase)
-
How long your cable needs to be
-
What you need to know about load capacity and safety
-
And how to quickly make the right choice
Step 1: What type of plug do you need?
In Europe, there are two standards: Type 1 and Type 2. Almost all modern EVs (from 2018) use Type 2.
| Plug type | Common with | Features |
|---|---|---|
| Type 1 | Old models from Asia (Nissan Leaf, Mitsubishi) | Single-sided connection, 1-phase |
| Type 2 | European models (Volkswagen, Kia, BMW, Tesla, Peugeot, etc.) | Most common, suitable for 1-phase and 3-phase |
Are you unsure? Check your charging port or check your manual. Bar2Charge is also happy to help you via chat.
Step 2: Determine your car's charging capacity
Not every EV can charge at full power. The maximum loading capacity the type of your car determines which type of cable you need:
| Car charging capacity | Required cable |
|---|---|
| 3.7 kW (1-phase 16A) | Type 2 – 1-phase 16A cable |
| 7.4 kW (1-phase 32A) | Type 2 – 1-phase 32A cable |
| 11 kW (3-phase 16A) | Type 2 – 3-phase 16A cable |
| 22 kW (3-phase 32A) | Type 2 – 3-phase 32A cable |
Please note: using a heavier cable than necessary is possible, but conversely, you will experience slower charging or errors.
Step 3: How long should your charging cable be?
The best-selling lengths are:
-
5 meters: standard, suitable for driveway or public bollard
-
7 meters: if your charging port is on the other side of your car
-
10 meters: only if really necessary; heavier and more expensive
Choose as short as possible for convenience, safety, and less weight loss.
Example: popular EVs and suitable charging cables
| Model | Plug type | Max. power | Recommended cable |
|---|---|---|---|
| Kia Niro EV | Type 2 | 11 kW | Type 2 – 3-phase 16A, 5m |
| Tesla Model 3 | Type 2 | 11 kW | Type 2 – 3-phase 16A, 7m |
| Renault Zoe | Type 2 | 22 kW | Type 2 – 3-phase 32A, 5m |
| Volkswagen ID.4 | Type 2 | 11 kW | Type 2 – 3-phase 16A, 5m |
| Nissan Leaf (older) | Type 1 | 3.7 kW | Type 1 – 1-phase 16A, 5m |

Safety: why not every cable is suitable
A cheap cable from an unknown brand seems attractive, but can pose risks:
-
Overheating during prolonged charging
-
No correct communication with charging point
-
Insufficient protection against leakage current
-
No CE/TÜV certification
Always choose a reliable cable with the correct certifications.
Bonus: what is the difference between coiled cable and straight cable?
Spiral cables They are handy if you want a tidy look. They retract automatically. The downside? They are often usable for a slightly shorter time than their length suggests.
Straight cables are more flexible and suitable for longer distances, for example between the sidewalk and the driveway.
Frequently Asked Questions
Can I use a 22 kW cable with an 11 kW car?
Yes. You simply charge at 11 kW. The cable is 'overqualified' and therefore future-proof.
Is 1-phase or 3-phase better?
3-phase is faster, provided your car and meter box support it. For home use, 11 kW (3-phase) is ideal.
What if I choose the wrong cable?
You can charge, but possibly more slowly or with interruptions. Safety and efficiency are then not optimal.
Conclusion
Choosing the right charging cable starts with:
-
It type of plug (usually Type 2)
-
The loading capacity of your EV
-
The desired assets and the right one length
Invest in a reliable, approved cable; it is the link between your car and safe charging.
