Hybrid energy storage systems for high-performance hybrid electric vehicles

In recent years, the hybrid electric vehicle (HEV) has come to the forefront as the leader for alternative fuel vehicles. With the increased demand for HEVs, more research has gone into the improvements of these vehicles. In order to achieve better performance in terms of miles per gallon, speed, and power, researchers have focused on many elements of the vehicle and how these elements affect the overall vehicle performance. One such element that has been a highly discussed topic has been the battery systems. Current battery technology has been a limiting factor when it comes to some aspects of the overall performance of the vehicle. There have been many developments on battery technology to increase cell life and performance. In order to achieve a better performing energy storage system, the concept of hybrid energy storage systems has been discussed. With the combination of different energy storage devices, the energy storage system can be improved to be for adept to accepting high regenerative braking current as well as endure high dynamics when it comes to driving performance.
