Johnson Controls3 Transportation Sustainability – the Challenges are Well Known Economic Disruption Oil to reach $100/barrel by end of '08 Tuesday October 2, 4:29 pm ET By Adam Schreck, AP Business Writer FROM: Energy Security Environmental Risk nz/sustainable-resource- use/climate/impact-on- industries/greenhouse.jpg Resource Impact

Johnson Controls4 Globally, the Transportation Sector Accounts for 24% of all CO 2 Emissions A mid-size automobile driven 24,000 km per year will emit approximately 5 metric tons of CO 2 annually Some forecasts project that the current global population of 700 million automobiles could reach 1.2 billion by 2030 In absence of significant improvements in powertrain efficiencies, annual CO 2 emissions from the transportation sector could exceed 10 billion metric tons by 2030 The non-OECD countries will account for the majority of this increase, about 60% Non-OECD Countries  Brazil  China  India  Russia

Johnson Controls5 A Spectrum of Technologies can Reduce Oil Consumption and CO 2 Emissions Hybrid and electric technologies significantly improve overall vehicle efficiency Energy Efficiency is the Lowest Total Cost Strategy for CO 2 Abatement

Johnson Controls6 Types of Hybrid Electric Vehicle (HEVs) Micro (a.k.a Stop/Start) Low voltage Shuts down engine at idle to save fuel Example: BMW 1,3 mini series – JCI is the world leader in AGM micro hybrid batteries Mild Low to medium voltage Includes stop-start, regeneration braking and acceleration assist Example: GM Saturn VUE Full hybrids High voltage Includes all mild HEV features PLUS electric-only operating range and optionally, multiple axle electric drive Example: Ford Escape There are Multiple Types of Hybrids…

Johnson Controls7 There are Multiple Types of Hybrids… Plug-In Hybrid (PHEV) High voltage Includes all full hybrid features PLUS electric-only operation for ~20 miles Ability to recharge battery through 120V electrical outlet (in addition to regenerative braking) Demonstration vehicles: GM Saturn VUE, Dodge Transit, Ford Escape Electric Vehicle High voltage No internal combustion engine Recharge battery through 120V electrical outlet No models in production Fuel Cells High Voltage No internal combustion engine Full gas hybrid functionality Demonstration vehicles: Daimler, Ford, Honda, Toyota

Johnson Controls8 Micro Hybrid Vehicle Fleets Mild Hybrid Vehicle Fleets Full Hybrid Vehicle Fleets PHEV Vehicle Fleets Battery Innovation “Fuels” the Drive To Sustainable Transportation Technology Phased Technology Roll-out and Commercialization Fuel Efficiency & CO 2 Reduction Benefit Pure Electric Vehicle Fleets 5-8% 12-20% 25-40% 60%- 100% 100% Commercially Available Under Development Available NOW

Johnson Controls9 Incremental Steps Can Have a Significant Impact Mild hybridization of just 25 percent of the new vehicle fleet over the next 23 years would have the equivalent emissions impact of eliminating 6 percent of the current global automobile fleet 43 Million Automobiles Hybridization achieving a 20% MPG improvement in ¼ of the new vehicles Reduced CO 2 Emissions of 215 Million Metric Tons

Johnson Controls10 Nickel Metal Hydride is today’s battery technology Li-Ion is the target of every OEM as the obvious next step battery solution WHY? { 30% Smaller 50% Lighter 30% Smaller More Energy More Powerful Faster Recharge Enhanced Cycle Life Li-Ion is the Next Battery Technology for Hybrid Vehicles
