Electronic control in electric vehicle based on CAN network

Bus-multiplexed structure of electronic systems in electric vehicle has many advantages. The most important is the connective reduction (size and length of wires) that reduces the electromagnetic interference, which is agreed with EMC (electromagnetic compatibility). In addition, only two wires are required to manage a different system, which necessitates an exchange of date between them. This can only done by networking, using a controller area network (CAN) bus. After a brief introduction of the need for the CAN network in embedded system particularly in electric vehicle application, we describe necessary acquired data in electric vehicle system. Then we present the new developed unit band on CAN network, for date control and acquisition in different levels: conception, structure and links with other systems.
