1 The Hybrid Car: A look at the future of cars By:Kenneth Barnett
2 What makes a Hybrid?A hybrid is anything that uses two or mores sources directly or indirectly to provide propulsionExamples of hybrid vehicles being used:Gasoline-pedal:MopedDiesel-electric:LocomotivesBusesSubmarines (can also be nuclear-electric)Gasoline-electric:Passenger Vehicles
3 Parallel HybridHas a fuel tank that supplies gas to the engine like a regular carIt also has a set of batteries that run an electric motorBoth the engine and electric motor can turn the transmission at the same time.
4 Series HybridThe fuel tank goes to the engine, but the engine turns a generatorThen the generator can either charge the batteries or power an electric motor that drives the transmissionThe gasoline engine does not directly power the car
5 Components of a Hybrid Gasoline engine Fuel Tank Much like our engines but smaller and is made with advanced technologies to reduce emissions and increase efficiencyFuel TankEnergy storing device for the gasoline engineGas has a much larger density than the batteriesExample: 1,000 pounds of batteries store as much energy as 1 gallon (7 pounds) of gas
6 Continuing Components Electric MotorAdvance electronics allow it to act as either an motor or a generatorExample: When needed it can take power from the batteries to accelerate the car. Or as the car slows down it acts as a generator and returns that energy to the batteriesGeneratorSimilar to an electric motor, just it acts only to produce electrical powerMainly in series hybrids
7 Continuing Components BatteriesEnergy storage device for the electric motorTransmissionTransmission on a hybrid performs the same as a transmission on our carsHow a transmission works is that it takes power from the engine or motor and sends to the driveshaft which turns your axle to move your car
8 Hybrid PerformanceThe key for the hybrid car is its ability to use a smaller engineA conventional engine is sized for peak power requirement, when a study shows that most drivers reach this less than 1% of our driving timeThe hybrid engine is sized for running at the average power not the peak. But when it does reach that point that it needs help up a hill or to pass someone, it draws extra power from the batteries and the electric motor to get the job done.
9 Hybrid Efficiency Recovers energy and stores it into the battery Regenerative brakingSometimes it will shut the engine offReduces aerodynamic dragLow rolling resistance tiresStiffer and inflated more1/2 the drag on the roadLightweight MaterialsCarbon fiberMetalsAluminumMagnesium
10 Hybrid Maintenance Warranties Brake pads Batteries The average warranty for a hybrid now is around either 8 yr/ 100,000 mile or even 10 year/ 150,000 mileBrake padsRegenerative brakingBatteries$6800 for new Toyota and Honda hybridBut batteries tested to go for 180,000 miles and some
