  1. Hy-wire cars -BY ASHISH PANDEY (TE MECHANICAL)

  2. Introduction • The Hy-wire (Hydrogen drive-by-wire) is a concept car from General Motors originally introduced in January 2002. • The car runs on hydrogen fuel cells. • Uses a drive-by-wire system, meaning that the car is controlled electronically. • No need of conventional engine. • All equipments needed are in a very compact place.

  3. Why Need HY-WIRE CAR

  4. MAKING MORE ROOM • An internal combustion engine requires a lot of additional equipment to function correctly. • No matter what else they do with a car, designers always have to make room. • The same goes for mechanical and hydraulic linkages. • But the basic function of a car remains the same however they are built.

  5. POLLUTION CONCERNS

  6. HY-WIRE BASICS

  7. Drive by wire system • A computer actually operates the components that move the wheels, activate the brakes and so on, based on input from an electronic controller. • Electromechanical actuators and human-machine interfaces such as pedal and steering feel emulators are used. • Very user friendly and comforting system

  8. BASIC STRUCTURE • There is no steering wheel, there are no pedals and there is no engine compartment.

  9. CHASSIS • Every piece of equipment that actually moves the car along the road is housed in an 11-inch-thick (28 cm) aluminium chassis at the base of the car. • Enough space inside. • Better drive view.

  10. Control and transmission

  11. HY-wire Car’s X-drive • It’s the user machine interface. • Can slide to either side of the vehicle • Has two ergonomic grips, positioned to the left and right of small LCD monitor.

  12. Control of X-drive

  13. POWER – HYDROGEN FUEL CELLS • They also generate electricity by chemical reactions like batteries. • Can be continuously recharged • Very efficient.

  14. Chemistry of a fuel cell

  15. How a Hydrogen Fuel Cell Works

  16. Fuel stack • Made up of 200 individual cells connected in series. • Collectively provide 94 kilowatts of continuous power and 129 kilowatts at peak power. • The motor controller boosts this up to 250 to 380 volts and converts it to AC current to drive the three-phase electric motor that rotates the wheels

  17. Other applications of fuel cells

  18. Hydrogen fuel cells are very efficient compared to what we have now

  19. Advantages

  20. SHORTCOMINGS

  21. FUTURE OF HY-WIRE CARS • General Motors says it fully intends to release a production version of the car in 2010, assuming it can resolve the major fuel and safety issues. • It is certainly a good illustration of various ways cars might evolve in the near future.
