Abstract | A comprehensive economic feasibility analysis and a cost-driven design methodology are essential to the successful application of hybrid electrical energy storage (HEES) systems in electric vehicles (EVs). This paper thus focuses on designing a cost-effective and high-performance HEES system for EVs, comprising of a supercapacitor bank and a lithium-ion (Li-ion) battery bank. In particular, the paper formulates the capacity provisioning problem for the EV HEES system so as to minimize the total system cost, utilizing accurate models of the battery cycle efficiency and state of health, characteristics of the supercapacitor bank, and dynamics of the EV. The aforesaid problem is subsequently solved by combining a gradient descent-based approach with a simulated annealing-based algorithm. Simulation results show that the proposed EV HEES system achieves 21% lower total cost per day and 30% higher fuel economy compared to a baseline homogeneous electrical energy storage system comprised of Li-ion batteries only. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
