1. ELECTRICAL & HYBRID VEHICLE

2. INTODUCTION In the modern era, the automotive industry is rapidly transitioning from traditional internal combustion engine (ICE) vehicles to more sustainable alternatives like electric and hybrid vehicles. This project explores the working principles, components, advantages, and future prospects of these technologies.

3. History of Electric & Hybrid Vehicles The concept of electric vehicles (EVs) dates back to the 19th century when early experiments with battery-powered cars were conducted. However, the rise of gasoline-powered vehicles overshadowed EVs for decades. Hybrid vehicles gained popularity in the late 20th century, with the launch of the Toyota Prius in 1997, revolutionizing the industry.

4. Working Principle of Electric Vehicles (EVs) Electric vehicles operate using an electric motor powered by a battery pack. The key components include: Battery Pack : Stores electrical energy. Electric Motor : Converts electrical energy into mechanical energy. Inverter : Converts DC from the battery to AC for the motor. Regenerative Braking System : Converts kinetic energy into stored electrical energy.

5. Components of an Electric Vehicle Battery Pack (Lithium-ion, Lead-acid, Solid-state, etc.) Electric Motor (DC motor, AC induction motor, or Permanent Magnet Synchronous Motor) Power Electronics Controller Charging Port Thermal Management System

6. Types of Hybrid Vehicles Hybrid vehicles combine an internal combustion engine (ICE) with an electric propulsion system. They are classified as: Mild Hybrid : Uses an electric motor to assist the engine but cannot run solely on electricity. Full Hybrid (HEV) : Can operate on electric power alone for short distances (e.g., Toyota Prius). Plug-in Hybrid (PHEV) : Features a larger battery that can be charged externally, allowing extended electric-only driving (e.g., Toyota RAV4 Prime). Series Hybrid : The electric motor drives the vehicle, while the engine acts as a generator. Parallel Hybrid : Both the engine and electric motor can drive the wheels.

7. Advantages & Challenges of EVs and Hybrids ADVANTAGES Environmental Benefits : Reduced greenhouse gas emissions. Energy Efficiency : Higher efficiency than ICE vehicles. Lower Operating Costs : Electricity is cheaper than fuel. Regenerative Braking : Improves energy efficiency .

8. Challenges: High Initial Cost : Batteries are expensive. Charging Infrastructure : Limited availability. Battery Degradation : Over time, battery efficiency decreases. Long Charging Time : Compared to refueling a petrol/diesel vehicle.

9. Future of Electric & Hybrid Vehicles The future of EVs and hybrids looks promising with advancements in battery technology, increased charging infrastructure, and government incentives promoting sustainable mobility. Solid-state batteries, wireless charging, and hydrogen fuel cell technologies are set to revolutionize the industry.
