SEMINAR ON HY-WIRE TECHNOLOGY
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
HY-WIRE BASICS

• The defining characteristic of the Hy-wire is
  that it doesnt 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
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
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

• 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.

• Cathode side
• O2 4H 4e- gt 2H2O
• Net reaction
• 2H2 O2 gt 2H2O

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 bodys
  electronics through universal docking ports.

X-Drive

• X-drive is the drivers 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.

• THE X-DRIVE CAN SLIDE TO EITHER SIDE OF THE
  VEHICLE

13
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

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 .

17

• 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

18
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.

19
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

20
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.
