A quick top-up can come with a few surprises. When you charge an electric car in public, the bill depends on more than how much electricity you buy. The network, payment method, time of day and length of your stop can all make a difference.
According to the Irish EV Association’s price tracker, updated on 2 November 2026, headline ad-hoc DC charging rates range from 60c to 87c per kWh, with some overnight rates lower.
For a 40kWh purchase, that means an energy bill of €24 to €34.80, before additional fees. The comparison covers operators’ own charging services; third-party roaming prices may differ.
With ESB introducing updated tariffs and its new Charge Smart overnight plan, here’s how to compare public charging costs
Where can you charge an electric car?
Public chargers broadly fall into two categories:
- AC charging: typically suited to longer stops while shopping, working or parking.
- DC fast and high-power charging: designed for quicker top-ups, including motorway stops.
Your car’s navigation, charging operators’ apps and tools such as PlugShare and A Better Routeplanner can help you find a charger. Before setting off, check the operator’s app for the individual charger’s availability and price.
For AC charging, you generally use the vehicle’s own Type 2 cable. DC charging uses a CCS connector, with the cable attached to the charging unit. SEAI’s charging guide explains the different charging options.
Finding a charger on a map is only the start. Check the connector, access conditions, opening hours and parking restrictions too.
How much does public EV charging cost in Ireland?
There is no single national tariff. The table below shows selected direct ad-hoc DC prices from the Irish EV Association’s 2 November comparison, rather than subscription or roaming rates.
| Operator or payment option | DC price per kWh | Energy cost for 40kWh |
|---|---|---|
| Certa | €0.60 | €24.00 |
| Lidl | €0.63 | €25.20 |
| Circle K | €0.69 | €27.60 |
| Applegreen Fast Charge | €0.73 | €29.20 |
| IONITY | €0.81 | €32.40 |
| ESB ecars contactless | €0.85 | €34.00 |
| InstaVolt | €0.85 | €34.00 |
Parking, access and overstay charges may add to the bill.
Some networks also have location-dependent or time-dependent prices, so check the tariff for the specific charger you intend to use.
ESB charging prices: what changed in November?
ESB’s updated Republic of Ireland tariffs took effect on 2 November 2026.
| Plan | Monthly subscription | Standard AC: up to 48kW | DC fast/high-power: 49kW and above |
|---|---|---|---|
| Pay As You Go account | None | €0.70/kWh | €0.83/kWh |
| Charge Lite | €4.79 | €0.65/kWh | €0.78/kWh |
| Charge Smart: 7am–9pm | €6.99 | €0.65/kWh | €0.78/kWh |
| Charge Smart: 9pm–7am | Covered by the same €6.99 subscription | €0.52/kWh | €0.66/kWh |
| Contactless | None | €0.72/kWh | €0.85/kWh |
All charging rates include VAT. ESB’s PAYG option is a registered account with no monthly subscription; its rates differ from those charged for one-off contactless payments
Charge Smart’s discounted rates apply between 9pm and 7am. During the day, its unit prices match Charge Lite’s.
The important distinction is between a cheaper unit rate and a cheaper monthly bill. A subscription saves money only when the charging discounts outweigh its fee.
Check ESB’s price plans before starting a session.
How to calculate your charging bill
The basic calculation is straightforward:
Charging cost = kWh purchased × price per kWh
Then add any session fees, parking charges, overstay fees and the relevant subscription cost.
It also helps to understand the difference between kW and kWh:
- kW measures charging power: how quickly electricity can be delivered.
- kWh measures energy: the quantity of electricity you buy.
A charger advertised as 150kW is not selling you “150 units” of electricity.
Worked example: charging a Volkswagen ID.4
The source material lists Volkswagen ID.4 battery options of 52kWh and 77kWh. For this example – the 77kWh version and a top-up from 20% to 80%.
That represents 60% of the battery’s capacity:
77kWh × 60% = 46.2kWh
Note: The costs below assume a purchase of 46.2kWh; an actual 20–80% charging session may require more billed electricity because of charging losses
| ESB charging option | Energy cost for 46.2kWh |
|---|---|
| Contactless DC at €0.85/kWh | €39.27 |
| PAYG account DC at €0.83/kWh | €38.35 |
| Charge Lite DC at €0.78/kWh | €36.04, plus subscription |
| Charge Smart overnight DC at €0.66/kWh | €30.49, plus subscription |
| PAYG account AC at €0.70/kWh | €32.34 |
| Charge Smart overnight AC at €0.52/kWh | €24.02, plus subscription |
The table also excludes parking, overstay charges and subscription fees.
If the overnight DC top-up were your only Charge Smart session that month, adding the €6.99 subscription would bring the total to €37.48.
That is about 87c less than the PAYG account example a smaller saving than the unit prices alone might suggest.
What does public charging cost per 100km?
For everyday running-cost comparisons, the cost per 100km can be more useful than the price of a “full charge”.
Cost per 100km = energy consumption in kWh/100km × price per kWh
The supplied figures from Volkswagen Ireland put official combined ID.4 consumption at 15.5–17kWh/100km. These are standardised WLTP figures, rather than a guarantee of what every driver will achieve.
Example – suppose your car uses 20kWh/100km:
| Charging rate | Illustrative energy cost per 100km |
|---|---|
| €0.60/kWh | €12.00 |
| ESB PAYG DC: €0.83/kWh | €16.60 |
| ESB Charge Smart overnight DC: €0.66/kWh | €13.20, before subscription |
For a more useful personal estimate, substitute your car’s observed consumption and account for the other charges you pay.
Is an EV charging subscription worth it?
Start with the network you actually use regularly. A low member rate offers little benefit if you rarely visit that operator’s chargers.
ESB Charge Lite: around 96kWh a month to break even
Charge Lite costs €4.79 per month and saves 5c per kWh against ESB’s PAYG account rates on both AC and DC charging.
That means you need to buy approximately 96kWh a month to recover the subscription fee through energy savings.
ESB Charge Smart: your charging time matters
Charge Smart costs €6.99 per month, with the strongest unit-price savings available overnight.
For DC charging between 9pm and 7am:
- Compared with PAYG: the saving is 17c/kWh. The subscription breaks even at approximately 41.2kWh a month.
- Compared with Charge Lite: Charge Smart costs an extra €2.20 a month and saves 12c/kWh overnight. Approximately 18.4kWh of overnight DC charging covers that additional subscription cost.
- For daytime-only charging: Charge Smart has the same unit rates as Charge Lite, with a higher monthly fee.
These calculations assume charging on ESB’s own network within the stated hours and exclude other differences in costs.
If you spread your charging across several networks, each subscription has fewer opportunities to earn back its fee.
Extra EV charging costs to watch for
The headline cents-per-kWh figure is only part of the calculation. These are the other costs and payment conditions worth checking.
Overstay fees can apply while your car is still charging
ESB charges 50c per minute after:
- 45 minutes on fast and high-power chargers.
- Ten hours on standard chargers.
The charge is capped at €22.50 per session. Staying 15 minutes beyond the DC threshold adds €7.50.
The threshold relates to session duration, rather than simply whether the battery has finished charging.
Other operators have their own rules. For example, the Irish EV Association tracker lists Maxol Recharge at 75c per minute after 30 minutes. Do not assume another network uses ESB’s thresholds or cap.
Access fees can make small top-ups more expensive
Some services charge a fee each time you start charging.
The Irish EV Association lists a €1.50 access fee for EZO’s ad-hoc service, alongside location-dependent energy prices.
Where a per-session fee applies, several small top-ups cost more in access fees than one equivalent larger purchase.
Charging does not necessarily include parking
Paying for electricity may not cover the parking space.
Check local signs for parking charges, maximum stays and access conditions. ESB’s terms make drivers responsible for applicable parking fees.
A card hold is not necessarily an extra charge
Some operators temporarily reserve money on your card before charging begins.
The Irish EV Association lists pre-authorisation holds of €25, €40 or €50 at various networks. These are not automatically additional charging fees, but they can temporarily reduce the money available to spend.
ESB’s terms distinguish card authorisation from the final payment.
App credit is different from your charging bill
Account top-ups can also affect how much money you need available.
ESB lists:
- A €20 initial account top-up.
- A €5 minimum balance to start charging.
- A €10 minimum subsequent top-up.
These are account-funding requirements, rather than separate session charges. They are worth considering if you use a network only occasionally and leave unused credit in its app.
Roaming prices may differ
A third-party app or charging card can make it convenient to access several networks, but its tariff may differ from the operator’s direct price.
The Irish EV Association’s comparison excludes roaming rates. Check the price in the app or service you will actually use to start the session.
Five checks before you plug in
Before starting a public charging session, check:
- Your payment-method price: make sure you are looking at the rate you will pay, rather than an advertised member price.
- Access fees: check for a charge to start the session.
- Overstay rules: note the time threshold, per-minute rate and any cap.
- Parking conditions: look for separate charges, maximum stays and access restrictions.
- Your energy requirement: work out how much you need for the next part of your journey.
For an occasional motorway stop, paying a slightly higher unit rate may make more sense than taking out a subscription you rarely use.
For drivers who rely on public charging, regular locations, charging times and monthly energy purchases are the figures that will help identify the best-value plan.
Have you ever been caught out by a charging fee — or found a plan that suits your routine?
