[Abstract]:With the development of automotive electronics and embedded technology, automotive electronics is developing towards the direction of digitalization, networking and intelligence. At present, CAN bus has become one of the most suitable buses for battery management system of body system because of its low cost, high reliability and real time. As one of the key technologies of electric vehicle, battery management system determines the performance and service life of battery, and also determines the performance and cost of electric vehicle. The reliability and configuration of battery management system based on CANopen protocol are very good. It will be the development direction of battery management system in the future. This paper briefly explains the research background and introduces the CAN bus and its high-level protocol. Combined with the development of battery management system, this paper introduces the bus protocol and CANopen protocol. Then the communication protocol is changed by using the original battery management system in the laboratory. The battery management system selects the chip CY8C3866 as the main control chip, then designs the hardware of the battery management system, and selects the LTC6803 chip to collect and monitor the battery voltage. After introducing the hardware design of the battery management system in detail, the software of the battery management system is introduced and designed in detail, including the main program design and subprogram design. In the part of software design, the monitoring program of CANopen protocol is specially designed, which is used to deal with the content of CANopen protocol itself. At the same time, the paper also introduces the hardware design of battery information collection and CAN communication module, and the estimation strategy of battery charge state (SOC). Finally, based on the designed hardware platform, the software development environment of the system is built, and the related experiments of battery management system are realized. Including battery charge and discharge test, current voltage temperature collection experiment, CANopen protocol communication test experiment, battery management system automatic test system experiment. The reliability and applicability of the application of CANopen protocol in battery management system are verified, and a more reliable and extensible communication method is provided for the future communication of battery management system in the whole vehicle system of electric vehicle.
