Hy wire-car

  1. 1. SEMINAR ONHY-WIRE TECHNOLOGY SARATH PRAKASH.V MECHANICAL ENGINEERING G.P.T.C KALAMASSERY
  2. 2. INTRODUCTION Cars are immensely complicated machines, but they do an incredibly simple job. Most of the complex stuff in a car is decided to turning wheel The two basic elements that largely dictate car design today are 1. The internal combustion engine 2. Mechanical and hydraulic linkages
  3. 3. HY-WIRE BASICS The defining characteristic of the Hy-wire is that it doesn’t have either of those two things: engine and mechanical and hydraulic linkages Instead of an engine, it has a fuel cell stack Instead of mechanical and hydraulic linkages, it has a drive by wire system
  4. 4. FUEL CELL –ON HY-WIRE A fuel cell is an electrochemical energy conversion device that converts hydrogen and oxygen into water, producing electricity and heat in the process. It provides a DC (direct current) voltage It can continually recharge a fuel cell by adding chemical fuel- hydrogen for an onboard storage tank
  5. 5. Proton exchange membrane fuel-cell The type of fuel cell that is used in the Hy-wire car is the Proton exchange membrane fuel cell. The four basic elements of a PEM fuel cell are:-  The anode, the negative post of the fuel cell  The cathode, the positive post of the fuel cell
  6. 6.  Electrolyte  It is the proton exchange membrane .  It blocks electrons . The catalyst It is a special material that facilitates the reaction of oxygen and hydrogen. It is usually made of platinum powder very thinly coated onto carbon paper or cloth. It is rough and porous . The platinum-coated side of the catalyst faces the PEM.
  7. 7. The working of PEMFC
  8. 8.  Chemistry of a Fuel Cell Anode side: 2H2 => 4H+ + 4e- Cathode side: O2 + 4H+ +4e- => 2H2O Net reaction: 2H2 + O2 => 2H2O
  9. 9. DRIVE BY WIRE TECHNOLOGY The ‘brain’ of Hy-Wire is a central computer housed in the middle of the chassis. It sends electronic signals to  The motor control unit to vary the speed.  The steering mechanism to maneuver the car.  The braking system to slow the car down . It is connected to an array of advanced sensors. The computer is connected to the body’s electronics through universal docking ports.
  10. 10. X-Drive X-drive is the driver’s control unit . It has two ergonomic groups , positioned to the left and right of a small LCD monitor. The color monitor in the center of the controller displays speed, mileage, fuel level and the rear- view images from video cameras on the sides and back of the car, in place of conventional mirrors. A second monitor, on a console beside the driver, shows you stereo, climate control and navigation information.
  11. 11.  THE X-DRIVE CAN SLIDE TO EITHER SIDE OF THE VEHICLE
  12. 12. Fuel-Cell stack It is made up of 200 individual cells connected in series. It collectively provide 94 kilowatts of continuous power and 129 kilowatts at peak power. It is kept cool by a conventional radiator system It delivers DC voltage ranging from 125 to 200 volts
  13. 13. THE HYDROGEN TANKS AND FUEL-CELL STACK IN THE HY-WIRE
  14. 14. ADVANTAGES 1. Fuel efficient - a fuel cell vehicle could provide twice the fuel efficiency of a comparably sized conventional vehicle 2. Environment friendly - the only bi-product formed is water, which is a non-pollutant. 3. High stability - a low center of gravity, gives the architecture both a high stability and superior handling .
  15. 15.  4. Highly spacious - As there are no linkages and engine lot of legroom space is available for the passengers. 5. Driver friendly – X-Drive can be taken to anywhere inside the car Gives the driver a clear view of the road and thus increases the drivability. 6. Freedom of individual expression – freedom of individual expression
  16. 16. DISADVANTAGES 1. Low safety -An electrical failure would mean total loss of control. 2. Storage and transportation of hydrogen fuels – production , transportation and storage of hydrogen for the on board fuel cell stack. 3. Pricing - With the current status of development, manufacturing of the Hy-wire cars on a mass scale would not at all be economical.
  17. 17. FUTURE OF HY-WIRE Fuel cells offer a promising alternative They need to be compelling, affordable, and profitable. The main challenge is in the field of storage of hydrogen
  18. 18. CONCLUSION The Hy-wire concept has so profoundly brought about changes in the automotive industry GM and other auto makers are planning to launch such a vehicle for the public usage by the year 2020.
