  • Abhinav Kumar Santoshi IIT(BHU),Varanasi
  •  A hybrid is a combination of two or more things.  In this case we mean a vehicle powered by two different power Sources  Electric motor/generator  Internal combustion engine
  • Conventional Hybrid Battery Electric Fuel Battery Fuel Battery Engine Motor/ Generator Engine Motor/ Generator Transmission Transmission Transmission
  • NO!!!!!  Hybrids existed in the late 1800’s  Cars could be fuelled by either electricity or ethanol  No regenerative energy
  • The answer is : Technology & Cost But The invention of the IGBT and other power electronic advancements 1970 onwards has made way for the modern hybrid electric vehicles.
  •  An electric propulsion system is comprised of three main elements: power electronic converter, batteries , motor, and its controller  DC Commutator Motor  Permanent Magnet (PM) Brushless DC (BLDC) Motor  Switched Reluctance Motor ( SRM)  Induction Motor

  • Standby 8% Fuel Tank 100% Engine Aero 3% 16% Engine Loss 76% Driveline Driveline Losses 3% POWERTRAIN 13% Rolling 4% Braking 6% VEHICLE-Related EVs 101
  • Micro Hybrid Eliminates Fuel Tank: 100% Standby 8% Engine Engine Loss 76% Aero 3% 16% Driveline 13% Rolling 4% Braking 6% Driveline Losses 3% Full Hybrid •Engine downsizing Reduces •Decoupling of engine and wheel Plug-in •Can eliminate engine entirely Mild Hybrid Reduces EVs 101
  •  Regenerative braking actually makes city driving     more economical. Fuel efficiency is greatly increased (twice). Emissions are greatly decreased. Dependency on fossils fuels can be decreased. Hybrids can be run on alternative fuels as well.
  •  Currently more expensive than conventional  Heavier than conventional, due to battery pack     and electric motors weight Limited battery life and expensive battery pack if you want to replace it More complex computer controlled systems May have drivability issues Expensive to repair
  •  More efficient diesel hybrids  Plug in hybrids  Fuel cell and plug in vehicles  Powering your house/business with your fuel cell/hybrid cars  And more
  •  •Chevrolet Tahoe Hybrid  •Honda Accord Hybrid  •Honda Civic Hybrid  •Ford Escape Hybrid  •GMC Silverado Hybrid  •GMC Sierra Hybrid  •Toyota Prius  •Toyota Highlander Hybrid  •Lexus 400h
  • According to the Business News on 12thApril, 2012, M&M is planning to Launch a full Hybrid Electric Vehicles in India in a couple of Years. http://www.livemint.com/Companies/z400EtgvamnPJZSzDrl5lO/Mahindra-developing-hybrid-vehiclelaunch-in-three-years.html Soon can be seen on Indian Roads.
  • “Sometimes being different is good enough, you need not be new all the time”  So, the HEVs have more efficiency, Low Fuel Economy, High Reliability and Less Air Pollution.  Optimum Utilization of these Vehicles will yield in good Results, especially Reduction of pollution.  It can prove to be vehicle of future.  If designed well, these hybrids can equal or better the utility, comfort, performance and safety we’ve come to expect, while saving us thousands of dollars at the gas pump.
