Charge Infrastructure, Charge Time and Electricity Supplier

The EV will be charged through three types of connection points (further detail on connection types and methods of payment may be found at ).  Any vehicle registered for the EV Grant Scheme by SEAI will meet the plug socket requirements for the national infrastructure planned by ESB.  The following sections list the main characteristics of the charging infrastructure which the Consumer should be aware of:

1.   Domestic Charging

·      Standard domestic Single Phase, 230 Volt, 16 Amp, 3.7kW

·      Outdoor Plug fitted externally to the Home within an appropriate distance (~1.5m) and appropriate access to the charge point on the vehicle

·      Used for every day journeys

·      Typical Overnight Charge time = 6-8 hrs

·      Electricity consumption added to electricity bill (see section below on Electricity Prices/Tariffs)

·      80% of all EV annual energy requirements are likely to be supplied through the Consumer’s own Domestic socket

·      The first 2,000 Domestic Sockets will be installed free of charge by ESB

2.   On-Street or Public Car Park Charging

·      Street Charger voltages examples:

·      Single Phase, 230V, 16 Amp, 3.7kW

·      Three Phase, 230V, 16 Amp, 11kW

·      Charge post with lock mechanism for plug socket

·      Activated by key-fob available from ESB

·      Customer Account or Pay-as-You method of payments likely to be available

·      Charge time = 2-6 hrs

·      As of the end of 2013, there were 700 public AC charge points (concentrated in urban areas). The majority of these chargers provide 22 kW. Installation locations include service stations, transport hubs, retail parks, on-the-street and car parks, among others.

- There are also 50 fast chargers (urban and intercity routes). All of these chargers support DC fast-charging (based on Chademo and CCS standards), and the future units will support 43-kW AC charging.

3.   Fast Charging

·      EVs entering the Irish market place have a forecasted range of 160km and the inter-city distances from one coast to the next in Ireland is likely to require a stop at a Fast Charger Station (or a Street Charger if time allows)

·      Example distances across Ireland:

·      Dublin to Galway = 208km

·      Cork to Dublin = 253km

·      Sligo to Dublin = 207km

·      Dublin to Belfast = 168km

·      The Fast Charging system to be deployed in Ireland will be the CHAdeMO fast charging system and vehicles must be CHAdeMO compatible in order to avail of this fast charging facility

·      This system can deliver 3-Phase DC current at 50kW

·      Charging time to fill a battery to 80% of its capacity is estimated to be 25mins

·      As of the end of 2013, ESB had installed 50 fast chargers around the country

·      Because of the higher energy involved, the transformer equipment is stored inside the Fast Charger itself which reduces the weight of the vehicle,

·      The Fast Charger will have its own unique plug type and cable with a single connection to the vehicle

·      A higher payment for the electricity purchased from these stations will be required for this electricity in order to reflect the higher equipment costs and day time electricity prices

·      More information on CHAdeMO can be found at

Electricity Payment and Tariffs

The prices and method of payment for energy sold at the On-Street and Fast Charging locations is currently under consideration but it is likely that a mixture of Pay-as-You-Go and Electricity Accounts will be available from 2011 to the Consumer.  In order to reflect the cost of installing, maintaining and administering the charging equipment together with the likely higher day time prices for energy, the electricity sold at these locations may be a little more expensive than the electricity purchased at home but still may be within the range of €1 to €2 for a typical battery charge on the Street.

It is estimated that 80% of the energy required for the EV will be sold via the Domestic electricity supply prices correct at time of writing (see <  link to Fuel Saving Calculation >).  A Consumer on for example an Urban 24hr Tariff with have an electricity energy unit price of 14.1cent per kWh (exVAT).  Alternatively a Customer on an Urban Night Saver Tariff will pay 7.45cent per kWh (exVAT).  It should be noted that switching from a 24hr Tariff to a Night Saver Tariff involves the installation of a meter which measures separate kWh consumption during day time and night time operating hours.  Night period occurs from 11pm to 8am in wintertime and 12am to 9am in the summertime.  Although there is no cost for switching to Night Rate Tariff, there may be a cost at some time in the future if the Consumer wished to change back again.  Consumers switching to the Night Rate Tariff get all of their energy consumption at the lower night rate tariff.  However the standing charge (eg 25c to 34.6c per day (exVAT) and the day time price for electricity will rise (ie 14c/kWh to 15c/kWh (exVAT).  The Consumer must therefore consider which tariff is most appropriate for their needs.

At the time of writing, there are no specific Prices or Tariffs available for the electricity sold to EV Customers (such as exist for night storage heating) but this may change in the future as the number of EVs on our roads begin to rise.

In the current electricity market a number of Domestic Suppliers are available so the Customer is advised to shop around for the most appropriate prices.  For a comparison of electricity tariffs available please see below links to a number of domestic electricity suppliers:
