A full hybrid electric vehicle (EV), also known as a strong hybrid, is a type of hybrid vehicle that combines a gasoline engine with a larger battery pack and a more powerful electric motor than mild hybrids, enabling it to drive solely on electric power for short distances and at lower speeds.
Key Characteristics of Full Hybrid EVs:
-
Electric-Only Driving: Unlike mild hybrids, full hybrids can operate solely on electric power for limited ranges, typically a few miles, and at lower speeds (e.g., city driving). This allows for zero-emission driving in certain situations.
-
Larger Battery Pack: They have significantly larger battery packs compared to mild hybrids, providing more energy storage for electric-only operation.
-
More Powerful Electric Motor: The electric motor in a full hybrid is more powerful, capable of independently propelling the vehicle.
-
Regenerative Braking: Full hybrids utilize regenerative braking systems to capture kinetic energy during deceleration and convert it into electricity, which is then stored in the battery. This enhances fuel efficiency.
-
Automatic Mode Switching: The vehicle's control system automatically switches between gasoline engine, electric motor, or a combination of both, optimizing performance and fuel economy.
-
Higher Cost: Full hybrids generally have a higher purchase price compared to mild hybrids due to the larger battery and more complex powertrain.
Benefits of Full Hybrid EVs:
-
Improved Fuel Economy: Full hybrids offer significantly better fuel economy compared to traditional gasoline-powered vehicles, especially in city driving.
-
Reduced Emissions: They produce fewer emissions than conventional vehicles, contributing to cleaner air, especially when operating in electric-only mode.
-
Electric Driving Capability: The ability to drive on electric power alone reduces reliance on gasoline and lowers running costs.
-
Smooth and Quiet Operation: Electric motor operation provides a smoother and quieter driving experience.
Examples of Full Hybrid EVs:
- Toyota Prius
- Ford Escape Hybrid
- Hyundai Sonata Hybrid
- Kia Niro Hybrid
Full Hybrid vs. Mild Hybrid
The primary difference between full and mild hybrids lies in their electric driving capabilities. Mild hybrids cannot propel the vehicle solely on electric power. Instead, the electric motor primarily assists the gasoline engine, improving fuel efficiency through features like start-stop and regenerative braking. Full hybrids, with their larger batteries and more powerful motors, offer both engine assist and electric-only driving.
