Track Your EV's Charging Costs and Service Dates

The EV owner's question: am I actually saving money?

You made the switch. Maybe the SEAI grant got you across the line (see our SEAI EV grants Ireland 2026 guide). Maybe petrol prices peaked and an EV just started making sense. Either way, six months in, the question becomes concrete: is this actually cheaper than the diesel or petrol I had before?

The honest answer: depends on your charging mix. An Irish EV owner who does 90% of their charging at home on a night tariff is running the car for a third of what a petrol equivalent would cost. An EV owner who relies on public DC fast-chargers for 50% of their kWh is only modestly ahead. The only way to know which camp you're in is to actually track it — kWh charged, where, at what cost, how many km you got from it.

What EV owners need to track differently from ICE

• kWh, not litres — every charge is recorded in kWh (energy), not volume. A 40 kWh top-up at home on a night tariff is a completely different economic event from a 40 kWh top-up at an Ionity gantry on an Irish motorway
• Charging location type — home / workplace / public AC / public DC fast. Your average cost per kWh is meaningless without knowing the blend
• Cost per kilometre — the only number that's comparable across an ICE and an EV. Your old Skoda did X cents/km; does your new EV do less?
• kWh per 100 km (the EV version of L/100km) — efficiency. Falls badly in winter, improves with experience, varies hugely by driving style
• Service items EVs still need — no oil, yes tyres / brake fluid / coolant / cabin filter / 12V battery / software updates / wiper blades. See below
• Motor tax €120 — still has to be paid annually, even though it's the lowest band
• Insurance renewal — the quote landscape for EVs in Ireland is still moving; shop around at renewal

Real Irish 2026 EV cost numbers

The numbers below are April 2026 figures for Ireland. They'll shift — but this is the current benchmark set:

How odo.ie handles EV charging

When you mark a vehicle as electric in odo.ie, the fuel page switches from "Fuel log" to "Charging log" and the fields adjust:

• kWh charged instead of litres
• Where did you charge? — a segmented picker with Public on one side and Home on the other. Home splits into your configured rate tiers (Day / Night / Average)
• Cost (€) — typed manually for public charges; auto-calculated (kWh × your home rate) when a home tier is selected
• Odometer (km) at time of charge
• Station (free-text) — only shown on Public charges. "ESB Dunkettle", "Tesla SC Athenry", "Ionity Cashel", "Workplace" — name it however makes sense. Slice the history later by station name
• Notes — optional: weather, driving mix, anything else

Home electricity rates

In Settings → Account → EV chargingenter your home tariff in €/kWh. Three optional tiers:

• Day — your standard daytime rate
• Night — NightSaver / EV-night window rate
• Average — use this if you're on a single 24-hour tariff, or for a blended all-day figure

Fill only the tiers that apply — only the configured ones appear as pills on the log form. A 24-hour-rate household sees just Ave · Public; a NightSaver household sees Day · Night · Public.

What odo.ie calculates automatically

• kWh/100km — your real-world efficiency trend
• Cost per km — the single comparable number vs your old ICE
• Home vs Public split — total spend in each category, with a per-tier breakdown (Day €X · Night €Y · Ave €Z) underneath
• Monthly spend — broken down in the running-cost analytics chart, including cost vs previous month and previous year
• Annual forecast — projected total cost based on trailing 12 months
• Cost per km (all-in) — not just charging, but including services, tax, insurance, everything logged against the car

Every charge takes about 10 seconds to log. After 3 months of data you have a clear, numbered answer to the "am I saving?" question — including exactly how much of your EV spend came from cheap home charging vs motorway fast-chargers.

The EV service schedule — what actually matters

EVs skip oil changes, cambelts, spark plugs, fuel filters and DPF regens. They still need these items, which sometimes surprises new EV owners:

Service interval for EVs

Varies by manufacturer — don't assume all EVs are on the 2-year / 30,000 km interval:

• Tesla: no mandated annual service — condition-based. Brake fluid every 2 years, cabin filter every 2 years
• Hyundai / Kia (Ioniq 5, EV6, Kona Electric, e-Niro): typically 12 months / 15,000 km — same as their ICE interval in Ireland
• Nissan Leaf: 18 months / 30,000 km
• VW / ID range: typically 2 years / 30,000 km
• BMW i3 / i4 / iX: condition-based with approx 2 years / 30,000 km target

Some Irish dealers require annual visits to maintain warranty even when the manufacturer interval is longer. Check your handbook and dealer warranty terms — and log every visit in odo.ie with date, garage, cost and what was done. A clean service record protects resale value and any warranty claim.

Motor tax & insurance for Irish EVs

Motor tax: €120/year, flat

Any pure BEV in Ireland pays €120 annually — the lowest motor tax band (0 g/km CO2). Still has to be paid each year at motortax.ie. See our motor tax rates Ireland guide and how to tax your car onlinefor the step-by-step. PHEVs are taxed on their CO2 band like any ICE — typically €140–€200.

Insurance: still 5–15% more than ICE

A persistent myth is that EVs are cheaper to insure in Ireland. In the UK this has largely come true; in Ireland the market hasn't fully re-priced yet. As of April 2026, most Irish insurers charge 5–15% more for a comparable EV vs ICE, driven by:

• Higher parts costs (bumper, lights, sensors often include aluminium structural bits)
• Fewer battery-certified body shops — repair times are longer, courtesy-car days add up
• Battery-replacement cost cap on total-loss assessments — a small collision can more easily total the car economically
• Limited data history — Irish insurers are still building the EV claims actuarial base

Mitigation: get quotes from at least 3 insurers. Some brokers (Liberty, FBD, AA Ireland) have been leaner on EV surcharge than the big incumbents; some mainline insurers have become more EV-friendly in the past 12 months. Full strategies in our car insurance Ireland guide.

Tracking seasonal variation

Irish EVs lose meaningful range in winter. Cold batteries hold less charge. Heaters draw more power. Wet tyres roll more. Your kWh/100km figure can rise 25–40% between July and January — which is a material change in your cost per km.

odo.ie's monthly-spend chart and trailing 12-month average make this visible. A typical Irish EV owner sees:

• Summer (May–August): 14–17 kWh/100km, ~€2.50–3 per 100km home-charged
• Winter (Nov–Feb): 18–24 kWh/100km, ~€3.50–4 per 100km home-charged
• Short-trip winter commute: the worst case — short trips from a cold battery don't let the pack warm up. Can hit 28+ kWh/100km

Knowing the seasonal pattern lets you plan — don't commit to a long winter trip on 80% charge if your winter efficiency figure says you'll need 90%. See our winter driving Irelandguide for the full pre-winter EV checklist.
