Advantages of EV Charging Infrastructure
An EV charging infrastructure serves as the "fueling station" for battery electric vehicles and plug-in hybrids. It offers designated parking spaces equipped with charging ports, enabling drivers to recharge their car batteries. For EV enthusiasts, this is a critical utility, especially as the UK moves toward phasing out petrol and diesel vehicles in the coming years. Therefore, building more accessible charging stations is crucial for widespread adoption.
UK officials are actively strategizing to expand the country's charging infrastructure, aiming to install around 300,000 units throughout the UK. But you might wonder, “Is such a large number really necessary?†The answer is yes, and here’s why:
- Convenient public charge points: Having more publicly accessible charging stations ensures that people can charge their vehicles regardless of location. This is particularly beneficial in rural areas and suburban neighborhoods where charging opportunities are limited.
- On- and off-street charging flexibility: While charging at home is ideal, having readily available charging stations while parked—whether at work or during long-distance trips—is incredibly convenient. This is especially useful for travelers who need to refuel quickly and efficiently.
- Smart charging capabilities: Smart charging systems offer cost savings through low-tariff usage and support vehicle-to-grid technologies. Such infrastructure not only benefits individual car owners but also helps reduce the strain on the national grid during peak charging hours.
Types of EV Charging Stations
Drivers with electric vehicles can choose from three charging levels or station types: slow, fast, and rapid.
Level 1 Charging (Slow Charging)
Also known as slow charging, Level 1 stations were among the earliest adopted methods for EV charging. These chargers are now predominantly found in homes, workplaces, and other locations where vehicles remain stationary for extended periods.
Rated at 3.6 kilowatts (kW), slow chargers take approximately 8-12 hours to fully charge a vehicle. This makes them perfect for overnight charging or when leaving a car parked for an entire day.
Level 2 Charging (Fast Charging)
Level 2, or fast charging, is the most common type of charging infrastructure in the UK. These alternating current (AC) stations typically range between 7-22 kW, offering a noticeable speed improvement over slow chargers.
Using a 7 kW charge point, a full charge can be completed in 4-6 hours, while a 22 kW charger can do the same in just 1-2 hours.
Level 3 Charging (Rapid Charging)
Rapid charging stations are the fastest method for EV charging, often located near major roads and motorway service areas. Rated at 43-50 kW, these chargers can deliver an 80% charge in just 20 minutes. After reaching this level, the system automatically cuts off to preserve the battery’s lifespan.
Unlike slower chargers, rapid chargers are tethered to the station via cables, and vehicles equipped with rapid charging capabilities can utilize these stations effectively.
Locations of EV Charging Stations
Both slow and fast chargers are available for both private and public use.
Private Options: Homeowners typically install chargers in their garages or driveways, preferring to charge their vehicles overnight. Consequently, slow chargers dominate this space.
Public Use: On the other hand, public charging stations are often found in communal parking areas, standalone units, or integrated into street furniture like lampposts. Dedicated hubs are also available near major roads and in public places like gyms, airports, hotels, and train stations, where vehicles are frequently left for extended periods.
Home Installations
Residential or home installations represent the most common type of EV charging hubs. Most homeowners opt for chargers in their garages or driveways, taking advantage of overnight charging to ensure their vehicles are ready for the next day.
About 70% of households in England already have off-street charging facilities installed, reflecting the growing popularity of EV ownership.
Public Charging Stations
Approximately 90% of UK EV drivers occasionally rely on public charging stations to top up their vehicles. These chargers are typically found in on-street locations, either as standalone units or integrated into existing infrastructure like lampposts.
Additionally, dedicated hubs are strategically placed in communal parking areas and along major roads to facilitate long-distance travel. Major destinations like airports, hotels, and train stations also feature charging stations, catering to drivers who leave their vehicles unattended for extended periods.
EV Charging Station Networks in the UK
National Charge Point Network (NCPN)
The National Chargepoint Registry maintains a database of EV charging networks across the UK, focusing primarily on public access points. Several notable networks operate in the UK:
- ESB Energy: Covers London, Birmingham, and Coventry, featuring over 140 chargers in each location.
- Osprey: One of the fastest-growing networks, stretching from Scotland to Cornwall with over 170 sites.
- Fastned: Offers renewable energy solutions across Europe, including stations in the UK’s North East, South England, and Scotland.
- BP Pulse: Operates an extensive network in the UK with over 8,000 fast and rapid charge points.
- Ecotricity (formerly GRIDServe): Features charge points in Wales and Southern England, plus EV forecourts in Norwich and Braintree capable of charging up to 24 vehicles simultaneously.
Open Charge Network
Open charge networks allow drivers to connect to multiple stations without needing separate accounts for each provider. This eliminates the hassle of managing numerous memberships and ensures seamless access to charging services across different regions.
EV Charging Station Costs
Regardless of whether you charge your vehicle at home or in public, there are associated costs involved.
Home Installation Costs
The average cost of a home battery charger ranges from £800 to £1,500, depending on the provider. A basic 3.6 kW slow charger may cost around £800, while tenants in rented properties can claim up to 75% of the cost, capped at £350, if eligible for grants and incentives related to plug-in hybrid electric vehicles.
However, the expense doesn’t end with installation. As consumers, we must also consider the cost of electricity. Assuming a vehicle with 60 kW automotive batteries and a 200-mile range, a full charge would cost approximately £17.
Public Charging Station Costs
Most public charging stations are free to use. However, some advanced RFID card- or app-enabled stations may require payment based on demand. Rapid chargers, for instance, could cost around £22 for a 30-minute, 90-mile charge.
