1. ADVANCEMENT IN HYBRID VEHICLE BY S.Pragalathan

2. 2 A HYBRID VEHICLE A hybrid vehicle is a vehicle that uses an on- board rechargeable energy storage system (RESS) and a fuel based power source for vehicle propulsion. These vehicles use much less fuel than their counterparts and produce less emissions Examples:  Diesel – electric  Fuel – electric  Gasoline - electric

3. 3 PARALLEL HYBRID Gasoline motor Batteries which powers an electric motor Both can power the transmission at the same time Electric motor supplements the gasoline engine

4. 4 SERIES HYBRID Gasoline motor turns a generator Generator may either charge the batteries or power an electric motor that drives the transmission At low speeds is powered only by the electric motor

5. 5 HYBRID VEHICLES –MICRO HYBRID Mahindra & Mahindra introduced the stop start based Micro Hybrid system to INDIAN AUTOMOTIVE MARKET

6. Electric Motor Drive/Assist  Additional Power to assist engine Accelerating, Passing and Hill Climbing.  So, allows Smaller and More Efficient Engine to be Used.

7. Automatic Start/Shutoff  Automatically shuts off the engine when the vehicle comes to a stop and restarts it when the accelerator is pressed. This prevents wasted energy from idling.

8. HEV Advantages  Reduced fuel consumption  Excellent gas mileage  Fewer tailpipe emissions  Lighter batteries than electric vehicles  Regenerative braking system stores electrical energy in Batteries  Uses less fuel to recharge batteries

9. CONCLUSION:- Thus we conclude that hybrid vehicle can reduce less emission and greater fuel consumption. And we can get more power from regenerating braking.
