3-Pin Plug Charger VS Dedicated Home Charger

3-Pin Plug Charger VS Dedicated Home EV Charger

You have just bought your first electric vehicle and you are wondering how you are going to charge it. Are you going to use a 3-pin plug charging cable? Or are you going to invest in a smart dedicated home charger? What are the differences? Which option is cheaper? Which is more convenient? The questions are endless and sometimes it can be rather overwhelming for someone who has just taken the plunge into the world of electric cars.

So, in this post, we are going to take a look at some of the key terms in relation to 3-pin plug charging and dedicated home chargers, and how they both work. We will then explain which is better in the fight between 3-pin plug chargers and dedicated home charge points.

But in short, a dedicated home charge point beats a 3-pin plug electric car charger, every single time.

3 Pin Plug EV Charger

So, what is 3-pin plug charging? And is it possible for me to charge my EV at home with a 3-pin plug charger?

3-pin plug charging is where you use a standard 3 pin domestic socket in your house to charge your EV. And yes, it is possible, but typically you will need a 3-pin plug car charger, either in the form of a Type 2 to 3 pin charging cable or a Type 1 to 3 Pin charging cable. Usually, this cable comes with your electric car, but it is different for each manufacturer, so please check your manual or with your vehicle manufacturer. To charge, simply plug the charger into a 3-pin plug socket in your home and plug the other end into your EV.

What is a dedicated home charger?

A dedicated home charger is usually a smart electric vehicle charging unit that is installed on your property. These smart units usually offer a wide variety of features, such as solar charging, charge scheduling and cable lock. You can either choose between a tethered or untethered (socketed) unit. Typically these units charge up to 7kW. You would have to select a charger that is compatible with your electric vehicle, this would be either a Type 1 or a Type 2 inlet, but again, this is different for each individual electric vehicle and you will find this in your EV manual.

You might be thinking, if I can charge at home with a three-pin socket, why would I invest in a dedicated home charging point?

Well, there are many reasons, but here are just a few:

1. Using a 3-pin charger frequently can be dangerous

A 3-pin domestic socket is not designed for continuous high-power usage and so most manufacturers recommend three-pin charging only in emergency situations. A 3-pin plug charger is a high-drain device, meaning that you will need to run your 3-pin socket at 2.3kW or even 2.5kW for long periods of time. Running a domestic socket this close to its maximum 3kW capacity puts a strain on your circuit, the cables, and the socket, with the potential to cause serious problems, such as overheating and in worst case scenarios, fires. This is not the case for dedicated home chargers, as they are designed to support the electric load needed to charge an EV, without any cause for concern.

2. Using 3-pin charging is the slowest way to charge your electric vehicle

Using a 3-pin socket is a very time-consuming way to charge your EV. It can take up to, or sometimes, over, 18 hours for a full charge using a 3-pin plug charger (Depending on your vehicle and the size of the battery). A 7kW dedicated home charger on the other hand, is over three times faster than a three-pin plug!

3. Using a 3-pin charger is inconvenient for everyone

In order to reach your electric vehicle, you may have to use an extension cable, or, you might have to thread wire through your window or door if you don’t have an outside plug. If an extension lead is needed, it must be rated at 13 Amps and must be fully unwound to prevent overheating. This means messy wires in and around your home for long periods of time. If you invest in a dedicated home EV charger, you can keep cords to a minimum, ensuring more aesthetic charging. You also don’t have to worry about any potential hazards in your home! With dedicated home chargers you also have the choice between tethered and untethered (socketed) units, meaning you choose whether you want your cable permanently attached to your unit, or not.

4. You don’t have access to a wide range of exciting smart features with 3-pin plug charging

With a dedicated smart home charger, you have access to an exciting range of features. Take the Hypervolt, for example, designed and manufactured in Britain, the Hypervolt Home 2.0 offers a variety of smart features such as Alexa voice control, charge scheduling and free over the air software updates. Other dedicated home chargers, such as the Zappee, have the ability to charge your electric vehicle purely using your solar panels! How amazing is that!

So, whilst you can use a 3-pin plug to charge your electric vehicle, it is not recommended by industry experts and EV manufacturers. Ideally, you should use only be using your three-pin plug  to charge your EV in emergency situations, or as a last resort, such as if you are staying at a family  or friend’s house.

Standard Installation
Our instant price is fixed if it falls within our standard installation package plus any additions that you have selected (extra cabling for example). This package covers the majority of homes in the UK. Before we undertake your installation we will carry out a digital survey to check that nothing has been missed. After reviewing the survey results some additional work may be required in order to complete your installation safely and to the required standards. If this is the case, we will contact you well before the installation date and advise the cost of any required work. You can then continue with your installation, or alternatively we will refund you in full if you do not want to proceed.

Included in our standard installation is :
• Fitting of a single phase charge point to a brick or plaster wall or other suitable permanent structure
• Up to 10 metres of cable, run and neatly clipped to the wall between the electricity supply meter / distribution board and the charge point.
• Routing of the cable through a drilled hole in a wall up to 500mm (20 inches) thick if this is needed.
• The fitting and testing of electrical connections and protections required for the charge point.
• An additional three way consumer unit, if required
• Installation of a Type A RCBO in an RCBO enclosure
• Up to 3 metres of plastic trunking to conceal interior wiring.
• An O-pen earth protection device if the charge point requires it. (This is NOT an earth rod)
• Up to 4 hours of labour from your installer to complete the work.
• Electrical testing of the whole installation.
• Handover and setup of the charge point and any app that may be needed.

Not included in our standard installation (additional work) :
• Where the installation requires additional cabling over and above the amount you have told us about.
• Upgrade/replacement of the main incoming supply fuse where the local DNO (eg Northern Powergrid) would need to attend site.
• If the charge point is to be mounted on a post/pedestal rather than an existing wall and where you have not selected a post as an extra cost option in your order.
• Installation of a charge point to a three phase supply.
• Where gas and water mains bonding (earthing) is not in place at your property. If this is not in place, additional work would be required before installation of the charge point.
• Any groundwork that has not been selected during the order process.

A Surge Protection Device is not included in our standard installation. 

What else you need to know :
• On the day of installation, please ensure that the area around your consumer unit (fuse box), incoming electricity supply meter and proposed charge point location (including where the cable is expected to be run) is clear and free of obstructions.
• We will need your WiFi password as part of the installation process in order to connect your charge point to the internet. Please have this available for the installer. Details will not be kept.
• The charge point must be on your own designated off road parking.
• The charger will be fixed in line with current guidelines at a height where it cannot be hit by a vehicle.
• Our installers are not able to enter loft spaces; lift floorboards or flooring; take apart any furniture of work above a height of 2m. If you anticipate that any of this may be required, then please contact us and we can discuss in more detail and provide you with a quotation.
• Should there be extreme weather conditions our installers may not be able to continue with you installation if it is not safe to do so (for example flooding). They will always do their best to complete the work where they can.
