EV chargers - Tethered vs Untethered
01 Sep 2022

One of the most noticeable differences between EV charge points is whether the charge point is tethered or untethered. If you are trying to understand the difference, you are probably close to purchasing an EV charger.

There is no right or wrong answer to this question, just a series of considerations to make to help you choose the right connection for your EV charger.

First let’s explore the difference between tethered and untethered and exactly what each term means.

Tethered EV charger

Put simply, a tethered EV charge point has a charging cable physically attached to the device. This means that the cable remains attached to the device at all times and can only be used at home. However, don’t let that put you off. Most new cars are sold with a detached cable so you will have the freedom to charge your vehicle away from home.

Now something you must consider is your vehicle's connector. The latest electric vehicles are fitted with a Type 2 connector, this is currently set as the EU standard. However, there are older models which require a Type 1 connector. If your vehicle requires a Type 1 connector, you may need to purchase a Type 2 to Type 1 Converter Cable

Also, consider where you will be charging your vehicle. A tethered EV charge point will have a set cable length. You must ensure this will reach the vehicle you are charging.

Here are some pros and cons of having a tethered EV charger

Pros

  • Your cable is attached and ready to be plugged into your vehicle.

  • Never forget where you left your charging cable

Cons

  • Purchasing the wrong charger length could lead to needing a new charge point.

  • Failing to wrap the cable neatly could lead to trips and falls, or even damage to your cable.

Untethered EV charger

You have probably guessed this already but untethered is the opposite to tethered in which the cable is detached from the charge point. Your charge point might look tidier on your wall but will require double the effort when charging your vehicle. Unlike the tethered option, you will need to plug your cable into your charge point as well as your vehicle. Although, there are some charge points which allow you to lock in your cable which would make the charge point temporarily tethered.

Cables come in different sizes and would be easier to adapt to changes in your parking arrangements.

Here are some pros and cons of having an untethered EV charger

Pros

  • More adaptable when it comes to moving the position of your parking arrangements

  • The charge point looks tidier when no cables are attached.

Cons

  • When charging at home, you need to connect the charger to both your charge point and vehicle.

  • The charging cable is easier to lose

An important point to note is that, whether you choose a tethered or untethered EV charger, you should expect the same charging performance from the charge point.
