| Abstract | Developing electric vehicles (EVs) has been chosen as national strategy as solution to energy security and urban air pollution by China. China has invested much to develop electric vehicle technologies. For EVs' penetration, China government develop `ten-city one thousand-EVs' demonstration program in 25 cities from 2008. For mass penetration of EVs, there still exist many challenges, especially for electric car for private use. How to promote EVs application based on present electric powertrain technologies has become an urgent demand for China government. Targeting to propose a kind of comprehensive trade-off method and to get the optimized powertrain parameters, such as battery capacity, in this paper, the simulation models were setup in Matlab/Simulink. The energy consumption model was setup, and based on that model, electricity consumption efficiency of electric sedan under NEDC and China city passenger car driving cycle were analyzed and compared. Based on energy consumption of a conventional reference car and a BEV, a comprehensive trade-off method for the average car user is proposed targeting to China market. The method takes into account the traction battery technology status and forecasting, vehicle daily kilometers travel, operating duty cycle, purchase price, fixed annual costs and operating costs, policy of EVs, etc. By the analysis, it can be concluded that A-compact type BEV, the AER designed sweet region should be no more than 200km under weight constrain. With higher battery capacities the amortization time becomes significantly longer, but from the systematic view, it is the less economical. Based on above analysis, the most cost-benefit designed AER with 50km VKDT should be 80km from view of minimum TCO of life cycle. So the optimized installed battery capacity threshold based on China VKDT is highly recommended. And the subsidy policy for EV should be modified more reasonable. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
