Abstract
The interest in electric vehicles (EVs) and Hybrid EVs (HEVs) increased and various prototypes were built to reduce the fuel consumption, which established the foundation of today's modern hybrid and electric vehicles. HEV combines a conventional propulsion system with an energy storage system, using both internal combustion engine (ICE) and electric motor as power sources to move the vehicle and therefore represent an important bridge between ICE vehicles (ICEVs) and EVs. Charging capabilities, strategies and power flow play a significant role in gaining wide acceptance of plug-in electric and hybrid electric vehicles in the market. The control of the grid operator is essential must be overridden in order to prolong the battery life and have the vehicle ready for operation. Melting and crystallization processes in polydimethyltrimethylene films were studied using temperature-modulated differential scanning calorimetry (DSC). Random copolymers with relatively high amounts of silmethylene comonomer have amorphous structure and low glass transition temperatures.
