Electric Vehicle Charge Points

 

Domestic Installations

There are predominantly, two types of E-V Charger for the domestic customer.

There is a “standard” 13 Amp EV Charger which is designed to be plugged in to a standard 13 Amp Socket Outlet found in your home or work and a “Full” 32 Amp+ E-V Charge Point.

Standard 13 Amp Charger

This type is a simple E-V Charger that is generally used for Hybrid Electric Vehicles and is designed to plugged into a socket at your home. These are designed to not exceed the maximum 13 Amps allowable at a standard socket and will “trickle charge” your vehicle.
This type of E-V charging is very common and is easy to integrate into your home without much fuss and can be very cost effective.
The downside to this type of charging is that it generally takes a number of hours to get a full charge into your vehicle which may cause an issue if you need to make regular trips to and from you home or place of work.

As far as we are aware, there is no load monitoring or app management software available for this type of charger.

Full 32 Amp+ Charge Point

This type of E-V charge Point is generally used for a fully electric vehicle but can also be used for hybrids and are designed to carry large current (Amps) to charge your vehicle quickly and efficiently.
A new, dedicated circuit will be required to be installed at your consumer unit (fuse box) in order to allow this device to operate.

Commercial/Industrial Applications
The two types of E-V Charge Points available to the Commercial and Industrial industry are as follows:

Single Phase E-V Charge Point

These devices are exactly the same as the above mentioned E-V Charge Points for the domestic user. The installation considerations points 1 through 5 are still applicable with the exception of point 1 whereby the chances of there being a shared electrical supply for this type of application are slim but not impossible so still has to be considered somewhat.

Three Phase E-V Charge Point

These devices are unlike any of the above mentioned devices in that they require 3 Phases to operate and therefore, further considerations will be required. Again, as mentioned before, the 5 main points of consideration will need to be followed but the emphasis will be more geared towards point 2 – Maximum Demand and 3 – Survey. With a 3 phase installation of this type, it is common for a dedicated E-V Charge Point Distribution Board to be installed which will be fed from a panel on it’s own dedicated Distribution Circuit. Generally, with this type of installation, an E-V Charging Station is to be installed which will require significant ground works and potential disruption to the day to day running of the business.

There are a number of factors which will need to be considered before any E-V Charge Point installation at your home which are as follows:

1. Shared Supply. Is your home on a “Shared Supply” – Some dwellings have an electricity supply which is shared with one or more of your neighbours. This is very common particularly in terraced homes of a certain era. If this is the case, an E-V Charge Point cannot be installed until the shared supply is converted to a dedicated supply. This is carried out by your local Electricity Supplier who may charge you for the service.

2. Maximum Demand. This is term that most people will not be familiar with but it something electricians have to consider for every new circuit installation. Maximum Demand is determined by the main fuse at your electricity supply head. There are 3 sizes currently utilised which are: 60, 80 and 100 Amps. An enquiry will have to be made to to your local Electricity Supplier to determine the fuse size which, in turn, will determine the Maximum Demand of your property. It is an offence for an electrician to pull the suppliers main fuse to inspect its sizing as it is the property of the local Electricity Supplier.
Essentially it comes down to this simple question, can your existing electrical installation cope with the additional load (current) that installing an E-V Charge Point will bring. Think of it this way, the additional electrical energy an E-V Charge Point will consume is the equivalent of a 8-10 KiloWatt electric shower.

3. Survey. If the above two points are satisfactory, a survey will be required to determine the method by which the E-V Charge Point will be installed. Is your current consumer unit (fuse box) able to accept an additional circuit and does the consumer unit comply with the current IEE BS7671 Wrining Regulations. How will the cable that feeds the new E-V Charge Point be installed and what is the route it will take. Knowing this will determine the cable type utilised and the method by which it will be installed (buried, clipped direct to the wall, in containment) etc.

4. Permission. Do you have permission to have the E-V Charge Point installed in the first place?
If you are a tenant of a property owned by a Landlord then permission must be sought before any installation can take place.
If you rent the property from a property management business, land owner or private individual then permission will need to be sought.
If you own the property but have a mortgage still outstanding then you will have to consult the fine print of your Mortgage Terms & Conditions as you may need to inform your lender of your intentions.
If you own your home outright with no mortgage then you are free to have anything installed and can ignore this point.

5. Insurance. Please be aware that if you have an E-V Charge Point installed at your property, then your buildings & contents insurance may need to be updated to reflect this.
Your insurer may consider this installation as an additional risk and therefore, increase your premium slighlty but, at least you will be covered if the worst should happen.

The above 5 points are the main factors to consider when deciding to have an Full 32+ Amp E-V Charge Point installed at your dwelling.
