A Novel Index for Batteries in Hybrid Electric Vehicles

Worldwide research is concentrated on making the Transportation Sector as environment friendly as possible. Replacing the IC Engine driven vehicles with Hybrid Electric Vehicles shall reduce the adverse impact of transportation sector on environment in a big way. But, there are inherent trade-offs between the battery goals for HEVs. Research is focused on developing a battery technology which satisfies these goals in a much better way. It can be observed that the present day battery technologies have many good performance characteristics, but have environmental issues associated with them. It is indeed a challenge to find a battery technology which has the best performance, while has a minimum environmental impact. This paper proposes a novel index for selecting the battery based on performance and environment friendliness.
