Dynamic Battery Analog Of Electric Vehicle And Management System Measurement In The Loop

Various countries begin to develop the electric and hybrid vehicles becauseof the environment pollution and oil shortage, which become the research hotpotsof automobile industry development in the21century, the battery manufacturerand vehicles manufacturer separately focus on the research of battery ontology inchemistry and electric direction, the schism of research direction cause the matchproblem between the battery management system and battery ontology.The dissertation introduce the development background of the electricvehicle batteries, battery integrated development and the hardware loopsimulation technology which is used in battery management system in electricvehicle. Meanwhile, the dissertation analyzes the typical battery model ofdomestic and foreign countries, proposes the scheme of N order of RC model inthe loop simulation model, and confirm the selection method of RC time constantin the three order RC model, the selection method of battery RC model isdiscussed through relevant test of battery charge and discharge and extractionbattery parameters. Software and hardware is designed in the loop simulationplatform after acquisition mode parameters, the aim of electric vehicle batterydischarge is reached in the hardware loop simulation, the battery systemhardware in the loop simulation platform realize the external characteristics ofthe battery simulation, test development of battery management system, researchthe vehicle compatibility of power battery box.Battery management system of electric vehicle is mainly real-timemonitoring battery status, so that the battery controller can timely get theinformation of battery. The main testing of battery management is the rest batteryelectricity, the state of rest charge are compared and analyzed between simulation model and battery management system, so that the function of batterymanagement system is verified.
