  1. 1. Three Major Issues Accelerated Global development of 1. Energy consumption of industry & technology fossil fuels in the 21st century 2. CO2 (global warming measures) Population growth (in USA, Asia, etc.) Growing number 3. Air quality of motor vehicles
  2. 2. Prius (THS) 1997~2003 Features of System 1 Two electric motors 2 Ni-MH battery 3 Power split device Power Control Unit Generator Inverter Battery Power split device Motor Engine Reduction Gear Mechanical power path Electrical Transmission for HV power path
  3. 3. Evolution of Hybrid Units •Continuous improvements (KAIZEN) •The challenge to achieve higher performance • Smaller, lighter units with improved output Inverter Main hybrid system units Generator Traction motor Battery
  4. 4. Prius (THSII) 2003~ Features of System 1 Two electric motors 2 Ni-MH battery 3 Power split device Power Control Unit Generator Inverter Battery Power split device Motor High-voltage boost Engine circuit Reduction Gear Mechanical power path Electrical Transmission for HV power path
  5. 5. Basic components Toyota Hybrid Synergy Drive® HV battery Pack improvements:  - 26% Modules (38  28 modules)  - 30% weight (56 kg  39 kg)  - 15 % volume (- 6 l)  - 23% static current drop  more efficient Added connection portion between each cell Module (6 Cells) Cell (1,2 V) 38  28 modules 273,6 V  201,6 V
  6. 6. Battery 1600 1400 Lighter ‘03 Prius (Prismatic resin case) Output density (W/kg) 1200 35%up 1000 800 ‘00 Prius Prismatic resin case 600 ‘97 Prius 400 (Cylindrical) 200 Smaller 0 0 500 1000 1500 2000 2500 3000 3500 Output density (W/L)
  7. 7. Toyota Hybrid Synergy Drive® Improvements Toyota Hybrid Synergy Drive® vs. THS: + 8% petrol power: 53 kW  57 kW + 50% electric power: 33 kW  50 kW + 14 % electric torque: 350 Nm  400 Nm over a 3 x wider range Substantial increase in contribution of electric motor Higher voltage to electric motor/generator: 273,6 V  500 V – superior power – minimised electrical losses Enhanced charging capacity of generator: more power and speed – 33,8 kW  37,8 kW – 6,500  10,000 rpm Newly developed battery pack – more compact and lighter (-30%) – superior output density – improved charge and discharge capacity Aluminium High voltage wire harness (weight reduction)
  8. 8. HV Market: Cumulative sales (worldwide) 1500 1 million Cumulative number of hybrid sales All HVs including other company’s HVs (Total) 1000 TOYOTA / LEXUS (Thousand) HVs (Total) PRIUS(Total) 500 PRIUS (US, Europe, …) PRIUS (Japan) 0 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 (Year
  9. 9. Irish Market Experience • Hybrid sales exceed 2,500 at end of 2008 • Mainly private buyers • Toyota Ireland role in promoting Hybrid • No.1 in customer satisfaction J.D. Power • Resale value is very strong • Appeal of Hybrid reaching a wider customer base
