Hybrid vehicles combine a traditional internal combustion engine (ICE) with one or more electric motors and a battery pack to enhance fuel efficiency and reduce emissions. According to the U.S. Department of Energy, hybrid vehicles use these components to optimize performance and energy consumption. The core structure includes:

• Internal Combustion Engine (ICE): A gasoline or diesel engine provides primary power, especially at higher speeds.
• Electric Motor(s): Assist the ICE, providing additional power for acceleration and sometimes enabling all-electric driving at low speeds.
• Battery Pack: Stores electrical energy for the electric motor(s), charged through regenerative braking and, in some hybrids, by the ICE.
• Power Electronics Controller: Manages the flow of energy between the battery, electric motor(s), and ICE.
• Transmission: Transfers power from the engine and/or electric motor(s) to the wheels.

These components work in tandem to maximize efficiency and performance.

2. What Are the Key Operational Principles of Hybrid Vehicles?

The operational principles of hybrid vehicles revolve around energy conservation and efficient power distribution, blending the strengths of both ICE and electric propulsion systems. These principles are supported by research from institutions like the University of California, Davis, which studies hybrid vehicle technology to improve efficiency. Key operational principles include:
