Battery Management System Based on AURIX Multi-core Architecture 2019-01-1310
Battery management system (BMS) is the core component of new energy vehicle battery system. With the increase of energy density of new energy vehicle battery, its control algorithm becomes more and more complex, and the task of battery management system will be more and more heavy. The hardware, software and control strategy model of battery management system are developed based on ARIX multi-core microcontroller. The minimal BMS system is developed by using AURIX265 + LTE35584 chip which meets the functional safety requirements. The dual-core processing of control strategy and individual information acquisition is realized, and the processing efficiency is improved. The three-tier software architecture of battery management system is developed based on the software hierarchical architecture. The graphical development of battery management system strategy model is realized by using MATLAB / Simulink. The results of bench test and real vehicle test show that the battery management system developed meets the application requirements of enterprises, and the batch matching is obtained in vehicle enterprises.
