Plug-in Hybrid Electric Vehicle (PHEV)
A Plug-in Hybrid Electric Vehicle (PHEV) combines a rechargeable battery and electric motor with a traditional internal combustion engine (ICE). The battery can be charged by plugging into an external power source, allowing short trips on electric power alone before the combustion engine engages.
How It Works
PHEVs have two powertrains working together. In electric mode, the vehicle draws power from its battery pack to drive an electric motor. Once the battery is depleted, the ICE takes over — either driving the wheels directly, acting as a generator to charge the battery, or both simultaneously.
The electric-only range of a PHEV is typically 30–80 km, enough for many daily commutes. After the battery is drained, the vehicle operates as a conventional hybrid, using the engine alongside the electric motor for improved efficiency.
Why It Matters
PHEVs can serve as a transitional step toward full electrification for drivers who need the flexibility of a combustion engine for longer trips but want to drive electrically for daily use. However, their environmental benefits depend heavily on how often the owner actually charges and drives in electric mode.
For buyers comparing options, it is important to understand that a PHEV is fundamentally different from a BEV — it still requires fuel and has significantly less electric range.
Common Values
- Electric-only range: 30–80 km (WLTP)
- Battery capacity: 8–25 kWh
- Combined range (electric + fuel): 600–900 km
- Charging: Typically AC only (3.7–7.4 kW), rarely supports DC fast charging
