A Guide to Selecting the Right Type of EV Charging Cable

Switching to an electric vehicle is an exciting step into a greener, cleaner future—but one of the first practical decisions you’ll face is selecting the right EV charging cable. With multiple options available, from Type 1 vs Type 2 to single-phase vs three-phase, it’s easy to feel overwhelmed.

At EVwired, we simplify EV ownership. In this guide, we’ll break down everything you need to know about EV charging cables, so you can choose the right one for your car, your charger, and your lifestyle.

Why Choosing the Right EV Charging Cable Matters

Using the correct EV cable isn’t just about convenience—it’s about safety, efficiency, and protecting your vehicle’s battery health. The right cable ensures:

Faster, reliable charging.
Compatibility with home and public charge points.
Safe operation in all weather conditions

Let’s explore how to get it right.

Step 1: Know Your EV's Plug Type – Type 1 or Type 2?

EVs sold in the UK almost always support Type 2 connectors, but some older or imported models may use Type 1.

🔌 Type 1 Cables

5-pin connector.
Single-phase only (up to 7.4kW).
Common in older US and Asian models.
Includes a latch to secure the connection.

Compatible With: Nissan Leaf (older models), Mitsubishi Outlander PHEV, and Chevrolet Volt.

🔌 Type 2 Cables

7-pin connector.
Supports both single-phase and three-phase charging (up to 22kW).
Standard for most European and UK vehicles.
Features a locking mechanism for added security.

Compatible With: Tesla Model 3/Y, BMW i3, Hyundai Kona, Kia e-Niro, VW ID.3, and Renault Zoe.

Step 2: Choose Between Single-Phase and Three-Phase Charging

⚡ Single-Phase Cables

Deliver up to 7.4kW.
Ideal for home charging.
Provides approx. 15–30 miles of range per hour.
Standard for most UK residential installations.

⚡ Three-Phase Cables

Delivers up to 22kW.
Suitable for homes with access to a three-phase power supply, workplace chargers, and public chargers.
Offers faster charging speeds.
Requires a three-phase compatible car and power supply.

Step 3: Decide on Cable Length and Style

5 Metres: Best for small driveways or garage use.
7 Metres: Offers extra reach for slightly awkward spaces.
10 Metres: Perfect for on-street parking or shared charging spaces.
15 Metres: Ideal for hard to reach areas and where extra length is needed.

Step 4: Weather Resistance and Safety Features

When buying a charging cable, it's important to look out for:

IP55 Waterproof & Dustproof Rating – Safe to use in UK rain.
Heat Resistance – Important for rapid charging.
Protective End Caps – Keeps connectors clean and dry.

Step 5: Where Will You Be Charging Most?

🏡 Charging at Home

You’ll likely need:

A Type 2 single-phase charging cable.
A compatible wall box or granny charger for 3-pin UK plug sockets.

⚡ Charging in Public

Most UK public charge points require:

A Type 2 cable (single or three-phase).
Faster speeds than home setups.
Make sure to carry your own cable—some stations don’t supply one.

Choosing the right EV charging cable may seem complicated at first, but with a little guidance, it’s simple. Whether you’re charging at home, work, or on the go, the right cable can make your EV experience seamless and stress-free.
