| Abstract | This paper deals with the optimized control strategy within the vehicle which is driven by a fuel cell stack hybrid with a NiMH battery. The aim is the instantaneous energy management to optimize the hydrogen consumption. At first the powertrain was modeled using data on testbed. Then the optimization control problem basing on an equivalent hydrogen consumption strategy is defined, where the motor target torque and DC/DC target current should be calculated. According to the shift signals and pedal position signals, the vehicle operation can be divided into two modes, non-brake mode (idle, drive backward, drive forward, slide) and brake mode. The optimization problem was solved respectively. Results in ldquoChina typical city bus cyclerdquo testing show the robustness and effectiveness of the strategy in improving fuel economy while maintaining drivability. The fuel economy was improved from 9.6 kg/100 km to 7.9 kg/100 km and the battery SOC was kept around 47%. |

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.
