The used-EV market in Ireland is the most underrated bargain in motoring right now. Cars that cost €42,000 new in 2022 are sitting at €22,000–€26,000 in 2026, and the running-cost case for an EV is unchanged. The catch: the inspection process is genuinely different from a used petrol or diesel, and most general motor traders don't know how to check the things that matter. This guide walks through the actual inspection.
1. Battery state-of-health (SoH) — the only number that matters
The battery is roughly 30–45% of an EV's value. Its condition is by far the biggest variable in whether you've got a bargain or a money pit. Never buy a used EV without a battery state-of-health (SoH) read. Period.
SoH is expressed as a percentage of the battery's original usable capacity. Anchor figures:
- SoH 95–100%: almost-new battery. Expected on cars under 18 months old or low mileage.
- SoH 90–95%: healthy. Typical for a 2–3 year-old car with 40,000–70,000 km.
- SoH 85–90%: negotiate price down. Range will be 10–15% lower than the brochure.
- SoH 80–85%: walk unless price is genuinely rock-bottom. Range degradation will be visible day-to-day.
- SoH below 80%: only buy if you understand exactly what you're buying. The Tesla and Hyundai/Kia warranty kicks in at 70% on most models — below that, the manufacturer replaces or repairs.
How to get an SoH read: any reputable Irish EV-specialist dealer will pull one for you on demand. For private sales or general traders, buy a Bluetooth OBD-II dongle (~€30) and a copy of the relevant brand's diagnostic app:
- Tesla: TM-Spy app on Android, or via the in-car Service Mode (ask the seller).
- Hyundai/Kia: Car Scanner app + the BMS PID for the e-platform cars.
- Volkswagen Group (ID range, e-tron, Enyaq): OBDeleven app with the correct license.
- Nissan Leaf: LeafSpy Pro — the gold standard for Leaf inspection.
- Renault Zoe: CanZE app (free).
If a seller refuses to allow an SoH read, that's your answer. Walk.
2. Charging-port inspection
The CCS charging port is the second-most-stressed component on a used EV. Inspect both pins and plastic surround for:
- Bent or rotated pins: indicates someone forced a connector. Will cause intermittent charging faults.
- Pitting or burn marks on the DC pins: the high-current pins (the lower two on a CCS plug). Indicates heavy fast-charging history; not a deal-breaker but factor into negotiation.
- Cracked plastic surround: usually cosmetic but lets water in. Replacement is €200–€500 depending on the car.
- Sticky / slow flap: the motorised flap on most BEVs. A failed mechanism is €150–€400 to fix.
If the seller can't put it on a fast charger during the test drive (most franchise dealers can; many private sellers can't), insist on at least a 7 kW AC charge to confirm the port works under load.
3. Software / firmware history
EVs receive routine software updates that fix charging behaviour, range estimation, and safety systems. A car that hasn't been updated for two years is missing meaningful improvements.
Per make:
- Tesla: check the firmware version in the in-car menu. Anything older than 2024.x is unmaintained.
- VW Group: check the MEB software version (should be 3.0 or later for ID range from 2022 onward).
- Hyundai/Kia: ask for the most recent service-record update entry.
- Polestar: the Polestar app shows firmware version directly.
4. Mechanical and chassis checks (the boring stuff)
EVs are heavier than equivalent ICE cars. That has implications for the wear items:
- Tyres: check for uneven wear (tracking issue) and remaining tread (insist on at least 4 mm front and rear). Replacing four EV-spec tyres is €700–€1,100; factor into the price.
- Brakes: EVs use less brake material because of regen, but inspect for corrosion. Lightly-used brakes can rust on a car that's been parked a lot.
- Suspension bushings: heavier cars wear bushings faster. Check for clunks on a slow-speed pothole and on full-lock turns.
- Coolant level: EVs use coolant for the battery and motor. Check it; if the seller doesn't know where the reservoir is, that's a flag.
- 12V battery: the small 12V battery still exists in an EV and dies just like in any other car. Check the date of the most recent replacement.
5. The cars worth avoiding
- Pre-2018 Nissan Leaf (24 kWh and 30 kWh): no active battery cooling. Heavy DC charging cooks the cells. Cheap for a reason.
- Renault Zoe ZE40 (41 kWh) without CCS port: charging is restricted to 22 kW AC. Long trips are painful.
- Early Tesla Model S (2014–2016): battery degradation can be unpredictable and replacement is €15,000+ at this age. Buy newer.
- Smart EQ ForFour: tiny battery, slow charging, awkward to live with. The market reflects this.
- BMW i3 with REx (range extender): the petrol generator is a maintenance liability and the battery in early cars is small. The pure-EV i3s of the same vintage are fine.
- Any ex-Norway / ex-UK private import without an Irish service history: not because the car is bad, but because the warranty position with Irish dealers may be limited. Confirm before you buy.
6. The negotiation move that always works
After the SoH read, charging-port inspection, and test drive, the move:
"Battery state-of-health is X%. The brochure range was Y. That means the real winter range on this car is Z — about [N] km lower than the equivalent fresh car. Looking at carzone.ie comparable, the price gap to a fresher car with full SoH is about €[delta]. I'd want to see that delta reflected in the price here, given the battery wear."
It works because it's true, it's specific, and it gives the seller a face-saving way to come down. Most sellers expect to negotiate €500–€1,500 on a used EV; the SoH-anchored argument typically gets €1,000–€3,000 off without any drama.
7. Warranty: read the small print
Manufacturer battery warranties for the most common Irish-market BEVs:
| Brand | Battery warranty | SoH threshold |
|---|---|---|
| Tesla | 8 years / 192,000 km | 70% |
| Hyundai / Kia | 7 years / 150,000 km (UK/IE 7-year general) | 70% |
| Volkswagen Group | 8 years / 160,000 km | 70% |
| Renault | 8 years / 160,000 km | 66% |
| MG | 7 years / 150,000 km (Irish-market new) | 70% |
| Polestar | 8 years / 160,000 km | 70% |
The warranty transfers to subsequent owners, but you typically need the car to be serviced at a brand-approved garage to keep it active. If you're considering a used BEV that's two-or-three years old, the remaining battery warranty is a meaningful asset; verify it's intact before the deal closes.
The summary checklist
- SoH read — insist on it. SoH below 85% means renegotiate.
- Charging-port inspection — pins, surround, flap.
- Firmware/software up to date.
- Mechanical checks — tyres, suspension, coolant, 12V.
- Service history — brand-approved garage entries.
- Warranty status — battery warranty intact and transferring.
- Test drive — motorway speed, regen modes, AC charging on the test.
- Negotiate — SoH-anchored argument is the most reliable.
