| Abstract | According to the communication structure of CAN BUS network on EV, this paper works out a SAE J1939 application layer protocol meet the system functional requirements, and designs the software and hardware for the system. First, design the CAN BUS work nod for EV, including the master node, the light node, air conditioning node, doors and instrument node, etc, and the draw the CAN BUS topology diagram. Meanwhile, according to the concrete situation of EV, work out an application layer protocol that consistent with the SAE J1939 protocol, and the information allocation table and message structure chart of CAN BUS network node is also presented. Secondly, design the hardware and software for the CAN BUS communication network. Hardware interface circuit mainly consist of CAN communication controller SJA1000, high-speed opt coupler 6N137 and CAN BUS driver 82C250, and design schematic circuit diagram for CAN bus system hardware. The software designs for CAN BUS network are mainly the design of CAN BUS data communication and exchange between nodes, and communication processing for switch-signal, analog signal. The design of software communication module includes CAN initialization unit, message sending unit, message receiving unit and the interrupt service unit. Finally, the CAN BUS network communication system the paper designed is applied to the new energy bus produced by CENS Energy-Tech Co., Ltd. which is dedicated in the Shanghai World Expo. From the battery voltage data collected when EV are running, we can see that the system is accurate, stable without number lost, frame dropping and transfer error in data communication. The design has practical value promoting the application of new energy vehicles. |

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.
