Hybrid Benefits

Hybrid Benefits. . 1. When stopping the vehicle, Allison Electric Drive automatically becomes an energy generator by converting vehicle energy into electrical energy.. 2. The electrical energy is then saved, by storing it in the Allison Energy Storage System for future use.. 3. When accelerating the vehicle, the stored electrical energy is used to accelerate the vehicle, saving fuel and reducing harmful emissions and noise, while improving comfort..

    3. Energy recovery through regenerative braking is key to hybrid technology Regenerative Braking

    5. Hybrid Benefits Improved Fuel Economy

    6. Hybrid Benefits Reduced Emissions

    7. Hybrid Benefits Reduced Brake Wear

    8. Hybrid Buses will yield other Fleet Cost Saving

    10. Hybrid Buses will Increase your Ridership

    11. Hybrid Buses will yield other Fleet Cost Saving

    13. Series Hybrid Architecture

    15. Parallel System Propulsion

    16. Engine operates independently (Series) CVT operation Electric dominated launch Mechanical path to final drive (Parallel) Lower costs Smaller overall package volume/mass Higher transmission efficiency An EV Drive-based hybrid system contains aspects of both Series and Parallel HEV powertrains HEV operating capability (both) Regenerative braking Strong acceleration assist Instant transient response Allison Parallel Hybrid

    18. Traditional package Looks like a familiar B 400R Therefore not intimidating to technicians Concentric electric motors provide electrically variable drive ratios .40 overdrive “Two-mode compound split parallel hybrid architecture” for

    19. A Continuously Variable Transmission (CVT) except it is done electrically (it is an EVT or Electrically Variable Transmission) Referred to as a “Vehicle Designer’s Dream” since it is infinitely variable with respect to output speed and torque Cool running since no torque converter or output retarder as heat generators. Only cool running AC Induction Motors for

    20. Input rating (continuous): 330 hp (246 kW) Rated input torque: 1050 lb-ft (1424 Nm) Rated input speed: 2300 rpm Mass: 919 lb (417 kg) for

    21. Target life is 6 years on a 12 year 40’ transit bus At 6 years, maintenance should be done on Allison Energy Storage System Customer can remove entire ESS and send to Allison Authorized Service Outlet Allison Authorized Service Outlet will: Replace battery cells Salvage and reuse ESS Enclosure ESS Electronics 6 Variable-speed Brushless Fans Customer can reinstall the ESS and run bus for its remaining 6 years of useful life Allison Energy Storage System

    22. No “end-of-life” battery failures to date in customer vehicles or Allison test vehicles ! Some have reached 3-4 years of operation Still targeting 6-years life Allison ESS continues be an excellent energy storage system for transit duty Allison Energy Storage System

    23. System Controllers Allison Transmission 1000/2000/2400 Series™ controller As used in 2005 Silverado HD pickup truck Very high quality Automotive volumes Two used with Mass: 6.7 lb (3.1 kg) total weight for 2 controllers

    24. Dual Power Inverter Module (DPIM) Specifically designed by Allison to meet customer needs Core Allison business One DPIM includes two inverters 600 Volts nominal DC 150 kW continuous 3-phase AC output Simply cooled by EVDriveTM cooling circuit Mass: 165 lb (75kg) SAE J1939 Control Communications

    25. Driver’s Selector Same as World Transmission 3000 Series, 4000 Series, B 300, B 400 or B 500 Driver instructions same as 3000 Series, 4000 Series and B Series Diagnostic code accessible for technician through selector

    26. Hybrid Engines Allison is engine neutral Smaller than normal Popular engine optimized for Allison Electric Drive Low noise and emissions Rated power: 40 foot: 245-270 hp 60 foot: 330 hp New Flyer 40 foot: ISL-280 hp 60 foot Artic: Caterpillar C9-330 hp Gillig 35 & 40 foot SF & LF: ISB02-210/260 dual hp

    27. Hybrid Engines Engine Longevity Engine will have an easy life with our hybrid Much less fuel consumed and lower horsepower demand = longer engine life (ask any engine expert) Longer oil change intervals: King County hybrid articulated bus didn’t change engine oil at 6K or 12K or 18K but did at 24K even though it didn’t need to be changed!

    28. Product Support

    29. OEM Releases – North America

    30. Warranty Coverage
