INTRODUCTION
Hydrogen fuel cellAll the conventional mechanisms
are replaced by Drive By Wire System.
combination fuel cell & Drive By wire technology.
Interiors of the Hy-Wire
Passenger Compartment – made of Fiberglass and Steel very spacious provides a magnificent view of surroundings Flooring of passenger compartment is flat
Interiors of the Hy-Wire
X-DRIVE CONTROL
-
All the engine parts are fitted in the chasis.
No brake pedals
This car being a concept car means it is not available for the public to purchase. This proves that the technology is there to make this kind of environmentally friendly car, just at a great cost.
Skateboard Chassis
• “Skateboard” Chassis – 11’’ flat piece of Aluminum metal houses all the parts
• ARTISTIC PICTURISATION OF THE CHASSIS
Advantages – for the driver
• Enhanced driving experience
• Less tiring
• Spacious interiors
• Less or nil maintenance due to near absence of any moving parts
• To steer – glide the grips up and down lightly
• To accelerate - turn either grip, just like turning the throttle on a motorcycle
• To brake – squeeze either grip
• Electronic motion sensors , translate this motion into a digital signal that the central computer can recognize
• X-drive can go anywhere in the passenger compartment – currently X-drive swings around to either of two front seats
• Two ergonomic grips , positioned to the left and right of a LCD monitor
• Braking and acceleration
WORKING OF FUEL CELL
• Producion of electrical power.
• Hydrogen + oxygen to create useable electrical current, water vapor and heat.
• Unlike a battery, they do not store energy - they convert it from one form to another.
Fuel Cell vs. I.C Engine
Energy efficiencyHeat engine: max efficiency ~30%Fuel cell: max efficiency ~60%
Emission reduction (near zero)
No moving parts no noise
Low-temperature operation
Modularity
Technical Specifications• Top speed : 100 mph (161 kph)
• Weight : 4185 pounds (1898 kg)
• Chassis length : 14 ft 3 in (4.3 m)
• Chassis width : 5 ft 5.7 in (1.67 m)
• Chassis thickness : 11 in (28 cm)
• Motor : 250 to 380 volt 3-phase asynchronous electric motor
• Crash protection : front and rear “crush zones” – to absorb impact energy
Advantages of the carBetter braking and steering
system.Negates usage of steering
column, reduces the number of moving parts
Increased capability due to fault monitoring and diagnostics
Pollution free
A Few ConcernsSafety.Inadequate crash protectionEnergy efficient methods are required.High cost of fuel cells Service and maintenance .Storage of hydrogen
Disadvantages
Lack of in-house talent for programming of software for the electronics
Electromagnetic Interference (EMI)Present limitations of technology makes it
an expensive investment
