|Thermal Management Challenges for Hybrid Vehicle PowertrainDrives|
|Keywords: HEV, Powertrain IGBT, Thermal Management|
|Hybrid and electric vehicle drivetrain development is occurring in many segments of the vehicle industry, including passenger automobiles, light and heavy trucks, construction and agricultural vehicles, military tracked and wheeled vehicles, and specialized vehicles such as mining transporters. Powertrain thermal management issues encompass both the electrical drives and, increasingly as the industry moves towards "more electric" vehicle drives, the battery packs or ultracapacitor array providing stored energy. Overall industry trends in vehicle powertrain developments, industry forecasts for battery developments, and the industry desire in some vehicle types to combine engine coolant loop and electrical drive coolant loop will be discussed. Impact of energy densification and operating temperature for battery packs and the impact on potential cooling solutions will be presented. Proposed and current development solutions for cooling systems will be presented.|
