What is FHEV?

Published in Hybrid Vehicles 2 mins read

FHEV stands for Full Hybrid Electric Vehicle; it combines a combustion engine with a battery, enabling operation using either power source independently or both together.

Understanding Full Hybrid Electric Vehicles (FHEVs)

A Full Hybrid Electric Vehicle (FHEV) offers flexibility in how it uses its power sources. Unlike mild hybrids, an FHEV can run solely on its electric motor for certain distances and at lower speeds, significantly improving fuel efficiency.

Key Characteristics of FHEVs

  • Dual Power Source: FHEVs utilize both a combustion engine and an electric motor, offering a blend of power and efficiency.
  • Electric-Only Mode: They can operate solely on electric power for limited distances, reducing emissions in certain driving conditions.
  • Regenerative Braking: FHEVs use regenerative braking to capture energy during deceleration, which recharges the battery.
  • Automatic Switching: The vehicle automatically switches between the engine, electric motor, or a combination of both, depending on driving conditions and power demands.
  • No Plug-in Charging Required: The battery is charged through regenerative braking and by the combustion engine, eliminating the need for external charging.

FHEV vs. Other Hybrid Types

Feature FHEV (Full Hybrid)
Electric-Only Mode Yes, for limited distances
Battery Charging Regenerative braking and combustion engine
Plug-in Required No

Benefits of FHEVs

  • Improved Fuel Efficiency: Utilizing electric power reduces fuel consumption, especially in city driving.
  • Lower Emissions: Electric-only operation results in lower emissions.
  • Reduced Fuel Costs: Greater fuel efficiency leads to savings at the pump.
  • No Range Anxiety: Having a combustion engine eliminates range anxiety associated with pure electric vehicles.

Practical Insights

  • FHEVs are ideal for drivers who want better fuel economy without needing to plug in their vehicle.
  • The electric-only range is typically shorter compared to Plug-in Hybrid Electric Vehicles (PHEVs).
  • FHEVs offer a good balance between traditional combustion engines and fully electric vehicles.
