The Complete Guide to Choosing an EV Charging Cable

EV charging cables play a crucial role in transferring power from a source to your electric vehicle (EV). There are two primary types of charging points: tethered charging points, which come with a charging cable already attached, and untethered charging points that require you to provide your own cable.

Untethered charging points, typically AC chargers with a capacity ranging from 3 kWh to 42 kWh, can be found in various public locations. If you want the flexibility to charge at these locations, owning a compatible charging cable is beneficial. You may encounter these untethered points at workplaces or can even install one at home.

Rapid chargers (50 kWh and above) are different, as they always come with a tethered cable.

The process of selecting an EV charging cable may appear overwhelming due to the various maximum charging speeds, prices, and lengths available.

This guide aims to clarify the necessity of a charging cable and guide you through the selection process that aligns with your charging preferences.

When Should You Consider Acquiring a Charging Cable?

If your charging needs are solely met by tethered chargers, a charging cable may not be necessary. However, this could limit your charging options in the UK as public chargers are frequently untethered.

Here are some scenarios in which you will definitely need a charging cable:

Untethered Public Charging Stations

As highlighted earlier, if you encounter untethered public charging stations across the UK, having a charging cable is essential. These stations feature universal sockets that accommodate any connector type.

Since not all public chargers are untethered, utilizing an app like Bonnet can help you locate these sites efficiently.

Bonnet provides access to an extensive range of charging networks, ensuring you find available untethered charging points easily.

Home Charging Solutions

With more individuals opting for home charging installations, EV owners can conveniently charge their vehicles at home. Most home chargers provide power in the range of 3 to 7 kWh.

Installation costs for home charging points fall between £740 - £900, but you can benefit from grants such as the OZEV EV chargepoint grant, which could contribute up to £350 towards purchase and installation costs.

Depending on your preference, home charging points can be tethered or untethered. If you choose an untethered option, remember to invest in a charging cable.

Charging Stations at Work

Similar to home installations, workplaces can also feature charging stations. These may have universal sockets, necessitating a charging cable for your EV while you’re at work.

This option allows EV owners to charge over extended periods while they work, making it a convenient choice.

Other Situations Where a Charging Cable is Beneficial

Vehicles with Type 1 Connectors

If your vehicle is equipped with a Type 1 connector, locating charging points could become challenging, as this connector type has largely been replaced by newer models.

For Type 1 EVs, it's advisable to leverage untethered charging stations with their universal sockets. A Type 1 cable may be necessary.

While it’s possible to use a Type 1 to Type 2 adapter at tethered points, this approach carries potential safety risks and is generally discouraged.

Using a Standard 3-Pin Plug

If you rarely charge at home, you might find it pleasant to know that you can use a regular 3-pin plug for charging your EV in a pinch.

Charging with a standard plug is limited to about 3 kWh and is most suitable for evening charges. Most EVs come equipped with a domestic adapter, but you can purchase one separately if necessary.

Keep in mind that frequent use may strain your home’s wiring; it’s safer to install a designated home charging point for regular use.

Do Electric Vehicles Include Charging Cables?

Most modern electric vehicles come with a Type 2 charging cable, though this varies by manufacturer. Confirming the inclusion of a charging cable is prudent before finalizing your EV purchase.

In instances where a vehicle lacks a cable, there is often an option to buy one as an accessory.

Owning a second cable can also offer convenience for charging at home and on the go. A carry bag for storing the cable is recommended for longevity.

When purchasing a pre-owned electric vehicle, make sure to inquire whether a charging cable is provided.

Guidelines for Selecting an EV Charging Cable

Identifying the Appropriate Connector Type

In the UK, the untethered charging stations utilize AC chargers with either Type 1 or Type 2 connectors, rendering cables for DC connectors unnecessary.

Your vehicle model and age dictate the connector type, so keep that in mind when selecting your charging cable.

Type 1 Connector

Type 1 connectors generally facilitate charging at about 3 – 7 kWh, providing approximately 12 miles of range for every 30 minutes of charging. These are typically found only in older electric vehicles and lack any locking feature to secure your car during charging.

Securing a charging cable is imperative for those with Type 1 connectors to charge at various locations.

Type 2 Connector

Type 2 connectors offer charging rates of 3 – 42 kWh, enabling approximately 75 miles of charge in a 30-minute window at maximum speed. As the European standard for AC connectors, they are common in the UK and come with an integrated locking mechanism to ensure secure connections.

You may require a Type 2 cable for charging at untethered home, public, or workplace charging stations.

Compatibility Between Type 1 and Type 2 Connectors

Type 1 connectors are not compatible with Type 2 connectors, and vice versa. To charge using either type, locate an untethered charging station equipped with a universal socket.

Determining the Charging Cable's Maximum Speed

Your charging cable should match the maximum single-phase AC charging speed of your vehicle.

For example, the Nissan Leaf offers a max single-phase charging speed of 6.6 kW, while the Jaguar I-Pace can reach 7.4 kW.

Selecting a cable with a speed less than your vehicle's can hinder your charging efficiency. While you can purchase a faster cable, it will only charge your car at its maximum speed.

Choosing the Correct Cable Length

The ideal cable length corresponds to the distance from your charging station to where you park your vehicle. A 7.5m cable is typically sufficient for most users, allowing ease of use without compromising on storage.

Should you need variations, opting for a longer cable over a shorter one is advisable as it increases compatibility with differing charging point locations.

Additional Considerations for Selecting an EV Charging Cable

Opt for a 32A Cable

When purchasing charging cables, look for those rated at 32A. Though 16A variants are more affordable, they limit your charging speed to 3.6 kW, while a 32A option can achieve 7.2 kW.

Select a Quality, Durable Cable

Investing in a high-quality charging cable is essential, as it safeguards your investment in an electric vehicle. Quality cables tend to be more flexible, easier to handle, and longer-lasting.

On the other hand, cheaper options often compromise durability, becoming inflexible or prone to wear in unpredictable weather.

Confirm Cable Recyclability

Eventually, all cables reach the end of their usable life. Therefore, opt for cables that can be recycled to minimize environmental impact.

Avoid Shorter Cables

While shorter cables are typically cheaper, they can lead to stretching and long-term damage. Ideally, select cables that are 5 to 10m long to match most charging stations’ requirements while ensuring easy storage.
