Understand Your EV Charger Requirements

Charger Type: Determine which level of charger is needed. EV chargers typically come in two levels:

  • Level 2:
    • Single-Phase Chargers (Up to 11kW): Operates on a 230V circuit and requires a dedicated connection. This type of charger is commonly used for businesses and offers a charging rate of 10 to 60 miles of range per hour.
    • Three-Phase Chargers (Up to 22kW): Operates on a 400V three-phase power supply, providing charging speeds of up to 22kW. This allows for faster charging, typically delivering up to 90 miles of range per hour, making it ideal for commercial locations with higher power demands.
  • Level 3 (DC Fast Chargers): Operates on a 400V three-phase power supply and is generally used for commercial purposes, offering rapid charging but requiring significant electrical infrastructure.

Connector Types: In the UK, the two main types of connectors are:

  • Type 2 Connector: This is the standard connector for Level 2 charging in Europe and the UK. Most EVs are equipped with Type 2 inlets, making it a versatile option for various models.
  • Combined Charging System (CCS) Connector: Used for rapid DC charging (Level 3), the CCS connector integrates the Type 2 connector with additional DC pins for fast charging. This allows vehicles to charge quickly at high power levels, typically found at motorway service stations and commercial sites.
  • CHAdeMO Connector: Used for rapid DC charging (Level 3), the CHAdeMO connector is an older standard and was commonly used by earlier models like the Nissan Leaf. While not as prevalent as CCS, it is still supported by some charging stations, particularly in areas with a significant number of older EVs.

Assess Your Electrical System

Electrical Capacity: Your site’s electrical system must be capable of handling the additional load of an EV charger, especially for Level 2 or Level 3 chargers, which draw significant power.

Upgrades May Be Needed: If your electrical panel doesn’t have sufficient capacity, it may need to be upgraded. This is particularly common in older buildings. Upgrades might include increasing the capacity of the existing electrical panel or installing a new one.

DNO Electrical Upgrades and New Connections: In some cases, your site may require upgrades to the connection with your Distribution Network Operator (DNO) to accommodate the increased demand. This could involve significant modifications to your electrical infrastructure, including the potential for a new connection or an upgrade to your current connection. It’s important to coordinate with your DNO early in the planning process to understand what changes might be necessary.

For a detailed overview of the regulations, permissions, and planning processes involved in EV charger installation, including interactions with your DNO, refer to my white paper: “Installation of Electric Vehicle Charging Stations (AC and DC) – Regulations, Permissions, Planning, and ENA Applications.”

Installation Location

Distance from Electrical Panel: The further the charger is from the main electrical panel, the higher the installation cost due to the need for more wiring, civil works and labour.

How Long Does It Take to Install?

Installation Timeline:

  • Simple Installations: If your electrical system is up-to-date and the installation site is near the electrical panel, the process can take as little as 2-4 hours.
  • Complex Installations: If electrical upgrades or long wiring runs are needed, the installation could take up to 1-2 days.

Large Hubs with Multiple DC Chargers: For large hubs featuring multiple DC fast chargers, the installation process is considerably more complex and time-consuming. Key factors include:

  • Civil Works: Extensive civil engineering works may be required to accommodate multiple chargers, including groundworks, installation of conduit systems, and the construction of dedicated charging bays.
  • CCTV and Security: Installing surveillance systems for security and operational monitoring adds additional time and complexity.
  • New Connections: Coordinating with the Distribution Network Operator (DNO) for new or upgraded connections can involve lengthy approvals and installation times.
  • Site Management: Effective site management is crucial for coordinating the various contractors and ensuring that all work is completed to standard and on schedule.
  • Programmes and Project Controls: Large-scale projects require detailed planning and adherence to programme schedules. Project controls such as risk assessments, quality assurance, and compliance with Construction (Design and Management) (CDM) regulations are essential to manage the scope and ensure safety and regulatory adherence.

Scheduling and Permits:

  • Permits: Depending on the works required, you may need to obtain permits, which can extend the timeline by a few days to weeks or even months. Depending on your installation some of the permits or applications that may be required are listed below:
    • Planning permission,
    • ENA (Electricity Networks Association) application,
    • DNO supply upgrade application,
    • Highways noticing.
  • Scheduling the Work: Depending on the labour availability and the scale of the installation, scheduling might add some time to the overall process.

Do I Need a Site Survey?

Importance of a Site Survey:

  • Assessment of Electrical Capacity: A site survey helps determine if your current electrical system can handle the new charger or if upgrades are necessary. We will normally request a copy of your electricity bill prior to any survey, this helps us to identify if there is a MIC (Maximum Import Capacity) in place and how close your system is to its maximum available supply.
  • Installation Feasibility: The survey assesses the best location for installation, considering factors like distance from the electrical panel, ease of access, and potential obstacles.
  • Cost Estimation: The survey helps provide a more accurate cost estimate by considering all relevant factors.

Who Conducts the Survey?

  • Qualified Electricians: Typically, a qualified electrician or one of our EV charger installation specialist’s will perform the site survey. This information is then relayed to our Design Engineers who complete the electrical and layout designs to enable development of the scope and estimate.

Is It Mandatory?

  • Not Always, But Highly Recommended: While not always mandatory, a site survey is recommended to avoid unexpected costs or complications during quoting and installation.

How Much Will It Cost?

Cost Breakdown:

  • Charger Cost: A Level 2 charger for commercial use can range from £1000 to £4000, depending on the brand and features and back office compatibility. Level 3 chargers are significantly more expensive, often costing between £15000 and £80,000 or more.
  • Installation Costs: Basic installations might cost between £2000 and £10,000. If significant electrical work is needed, costs can rise to £10,000 to £40,000 or more.
  • Electrical Upgrades: If your electrical panel needs an upgrade, this could add anywhere from £800 to £2,500 or more to the total cost.
  • Main Incoming Supply Upgrades: If you need an upgrade to your supply the cost can vary, from a few hundred if you have a MIC (Maximum Import Capacity) that is in place for reduced billing purposes and your DNO head (mains fuses) are capable of managing an increased load to tens of thousands if a full supply upgrade is required with network reinforcement.

Financing and Incentives:

  • Government Incentives: Check for any government grants or schemes that can offset the cost of the charger or installation. See our Evlution website for further details.
