What is a Hybrid Vehicle? Any vehicle that combines two or more sources of power that provide propulsion power is a hybrid
Have you driven a hybrid before?
Hybrid-Electric Vehicles Part of the Solution Hybrid s have a long history Some of the first cars built were hybrid 1898 Ferdinand Porsche built a hybrid vehicle that could travel up to 40 miles on battery alone In the first few years of the 20 th century, thousands of electric and hybrid cars were produced.
Hybrid Propulsion
Commercial Applications
Commercial Applications
Different types of Hybrid Drives Parallel Hybrid Both the gas engine and electric motor provide propulsion power through the transmission and driveline Series Hybrid The gasoline engine turns a generator which then either charges the battery or powers the electric motor which propels the vehicle. Only the electric motor provides propulsion.
How do Hybrids Work? A Hybrid-Electric Vehicle is a cross between an all electric vehicle and todays typical gasoline powered vehicle The gasoline internal combustion engine is the primary power source It is assisted by an electric motor, powered by an on-board battery pack
How do Hybrids Work? Integration of the two power systems handled by sophisticated control software Engine off at stop Electric motor provides power from stop to approximately 15-25 MPH Gas engine takes over at that point, with assist from electric motors as required
How do Hybrids Work? Battery Pack recharges itself during the course of vehicle operation by capturing energy from braking and deceleration Plug in Charging Not Required
Azure P1 Parallel Hybrid Architecture
Azure P1 Parallel Hybrid Architecture FEAD Starter/Generator & Motor Controller are used to start engine as well as allow for power generation by the engine
Azure P1 Parallel Hybrid Architecture Traction Motor/Gen in driveshaft area & Controller are used to propel the vehicle and for power generation during regenerative braking
Azure P1 Parallel Hybrid Architecture Electric Power Assist System supplies hydraulic assist for brakes & steering when engine is off
Azure P1 Parallel Hybrid Architecture DC to DC Converters step down the high voltage system from ~ 400V DC to ~14V DC in order to supply the 12V system on vehicle when engine is off
Azure P1 Parallel Hybrid Architecture VCU controls all hybrid components as well as engine start/stop
Azure P1 Parallel Hybrid Architecture Energy Storage System (Battery Pack or Ultra Capacitors) stores energy and operates in the 200 to 400 V DC range
Energy Storage System 288 Volt (nominal) Battery Pack Nickel Metal Hydride chemistry Liquid cooled using a dedicated low temperature cooling system
Component Location
Hybrid Technology Benefits Fuel Economy Improvements of 30-40% or more With hybrid technology, a smaller internal combustion gas engine may be used and still maintain the performance characteristics of a larger engine. Not consuming fuel when vehicle stopped
Hybrid Technology Benefits Reduced Greenhouse Gas Emissions GHG emissions reduced 30%
Hybrid Technology Benefits Reduced Maintenance Costs Longer Brake Life (as electric motors slow car, reducing brake wear) Oil Changes required less often Vehicle ICE not operating when stopped. Fewer turns of the engine, longer oil life
Hybrid Benefits Driving patterns will determine fuel economy savings City routes with lots of stop and go driving will provide largest savings Engine off at stop Electric motor doing much of the work as vehicle accelerates from standing stop City mileage better than highway mileage
Azure-Ford Partnership In 2006, Ford and Azure Dynamics signed an agreement for Azure to develop a parallel hybrid electric system for incorporation into Ford s E350 and E450 Cutaway and Commercial Stripped Chassis.
Partnerships Azure Dynamics hybrid electric powertrain system on Ford s E-350 and E-450 commercial strip or cutaway chassis Chassis built at Ford s Ohio Assembly Plant Hybrid system upfit at Utilimaster
E350/450 Hybrid Program Chassis Specs: 158 inch & 176 inch wheelbase E-450 (& then E-350) GVWR: 14,050 lb for stripped, 14,500 lb for cutaway (& lower GVWR s for E-350) 5.4L Gasoline engine with 5R110 auto trans Performance Specs: 30-40% improvement in fuel economy Engine start/stop Electric launch Regenerative Braking Assembly Partner Utilimaster is Azure s assembly partner & will be responsible for the assembly of all hybrid components to chassis regardless of the body that is then installed afterwards
What s Available Today? Azure Dynamics providing parallel hybrid systems for commercial truck applications Systems installed on E350/450 strip and cutaway chassis.
What is Available Today? Azure Citibus Series hybrid shuttle bus 24 passenger capacity
What does the future hold?
Hybrid-Electric Vehicles Part of the Solution ~345,000 Hybrid vehicles sold in 2007 49% increase compared to 2006 By 2010, there will be nearly 65 hybrid models to choose from various manufacturers Forecasted sales in 2010 nearly 775,000 units, or 4.6% of all vehicle sales.
Hybrid Market Growth Favorable legislative environment will increase scope and magnitude of available buy-down funds California AB118 Technological advances will accelerate growth and market adoption rates Plug-in hybrids offer additional fuel-economy economy savings Energy Storage Systems improvements (Lithium Ion, Ultracapacitors) will help drive growth
Hybrid Market Growth Ever increasing corporate mandates to be viewed as environmentally responsible
Hybrid-Electric Vehicles Part of the Solution Technology has gained interest of large commercial truck accounts. Fed Express, DHL, AT&T, Florida Power and Light, and Purolator incorporating hybrid technology into their fleets.
Plug-in Hybrids Very promising technology Unlike today s hybrids, require user to plug in Potential of 40-60 miles of range from electric system each charge Zero tailpipe emissions while operating in electric only mode Internal combustion engine provides extended range when needed Dependent upon battery technology advances
PHEV
Lithium Ion Batteries Proven technology in cellphones and laptop computers Unproven in automotive applications Major investments in this technology to bring to market post 2010 Investment estimated to be over $1 billion annually Panasonic EV Energy, Sanyo, Cobasys, Johnson Controls
Lithium Ion Batteries Ongoing research addressing commercialization obstacles Safety Cost Temperature control very important Economies of scale projected to drive prices below NiMH batteries over time Longevity Need comparable life expectancy under more difficult charge/re-charge conditions
