Abstract: One of the fastest growing automotive fields, hybrid electric vehicles (HEVs) presents
both opportunities and challenges HEVs are more fuel-efficient and environment friendly
compared to conventional vehicles Optimizing the power intake in HEVs allows the engine operation to be kept within the range designed for best fuel economy and lowest emission, while the motor/generator system either provides additional power input, or generates electricity using the excessive power from the engine It also recovers the kinetic energy in braking or coasting These advantages have attracted worldwide development interests for HEVs in the automotive industry Hybrid vehicle sales have exceeded $250k per year with 14 models available in 2007 Experts predict that hybrid vehicles will take at least 10% of the total vehicle market share in the next 5 years, and as a result, could affect 200,000 jobs in automotive related industries
This presentation will look at the enabling technologies in the HEV field:
The pros and cons of HEVs
Parallel, series, and planetary gear architecture
Energy storage challenges
Power electronics
Plug-in and what it means
Emerging issues in HEV
New opportunities in HEV related fields
