Plug-in hybrid electric vehicles (PHEVs) in Ireland
A Plug-in Hybrid Electric Vehicle (PHEV) offers the best of both worlds — combining electric power with a traditional petrol or diesel engine. You can charge a PHEV from a home or public EV charger, drive short distances on electric power, and rely on the internal combustion engine (ICE) for longer trips.
PHEVs are a practical stepping stone to full electric driving. They produce fewer emissions than traditional vehicles when used correctly and can help reduce fuel costs by running on cheaper, cleaner electricity for local journeys.

How does a PHEV work?
A PHEV has two power sources:
- An internal combustion engine (ICE), powered by petrol or diesel
- An electric motor and battery that can be charged from the mains
The car can operate using either the electric motor, the engine, or a combination of both — depending on driving conditions and battery charge levels. When the battery runs low, the vehicle switches to fuel mode, offering peace of mind for longer journeys.
The battery is recharged by:
- Plugging into a charger (home or public)
- Braking (regenerative braking)
- The internal combustion engine
Range Extender Electric Vehicles (REEVs)
A REEV is a specific type of PHEV with a small petrol-powered generator that recharges the battery when needed. Unlike traditional PHEVs, the engine in a REEV doesn’t directly drive the wheels — it simply maintains the battery charge, extending range in a more efficient way than using the fuel engine alone.
PHEV pros and cons
Advantages:
- Lower running costs: Save money on short trips by using electricity
- Extended range: Back-up fuel engine gives you ICE-level driving range
- Flexible charging: Recharge at home or use public charge points
Disadvantages:
- Limited electric range: Most PHEVs can only drive ~60km on electric power
- Must be plugged in: To get the full benefit, regular charging is essential
- Less efficient when not charged: Heavier than ICE or BEVs due to dual systems
- Still uses fuel: Tailpipe emissions are higher when driving in engine mode
PHEV vs BEV vs ICE: what’s the difference?
The key difference between these vehicle types lies in the powertrain — how energy is converted into motion:
- ICE (Internal Combustion Engine): Burns fuel to generate power through mechanical parts. Produces continuous emissions, even when idling.
- BEV (Battery Electric Vehicle): Fully electric. No emissions, no engine noise, and 90% fewer moving parts than an ICE car.
- PHEV: Has both an electric motor and a petrol/diesel engine. You can drive short distances emission-free, with the reassurance of a fuel engine for longer trips.
Charging a PHEV in Ireland
PHEVs can be plugged into standard home chargers or public charging stations. Most use a Type 2 connector for AC charging. Charging at home is usually the most convenient and cost-effective way to keep your PHEV’s battery topped up.
Charging speeds:
- Home charging (3.7kW–7.4kW): Fully recharges a PHEV battery in around 2–4 hours
- Public AC charging: Widely available across Ireland — many locations are free or low-cost

Frequently asked questions about PHEVs
How far can a PHEV drive on electricity alone?
Most PHEVs offer between 40 and 60 kilometres of electric-only range. Enough for short commutes or day-to-day errands. After that, the petrol or diesel engine kicks in to extend the journey.
Is it worth getting a home charger for a PHEV?
Yes. To maximise the benefits of electric driving, a home charger makes daily top-ups easier and cheaper than relying on fuel or public stations. Many PHEV drivers plug in overnight to keep the battery full.
Are PHEVs eligible for SEAI grants?
No. As of now, SEAI home charger grants are only available to owners of fully electric vehicles (BEVs). However, PHEVs can still be charged using the same infrastructure and equipment.
Can I use fast charging with a PHEV?
Most PHEVs are not designed for rapid DC charging. They typically use slower AC chargers (3.7kW or 7.4kW), which are ideal for their smaller battery sizes and overnight home charging.
Are PHEVs good for long-distance travel?
Yes. The fuel engine provides backup range when the battery is depleted, giving a driving range similar to a petrol or diesel car. This makes PHEVs ideal for those who drive both short and long distances.
