Abstract:

Under the construction of new power system，massive batteries are connecting the power system， which makes the development of IoT and big data technologies overwhelming. A data analysis and model verification method to analyze the operation characteristics of batteries is proposed. Firstly，the data acquisition and transmission modes of a battery are studied.Based on the parser and data extraction method of Controller Area Network（CAN）message， the specific algorithm is given.Considering the second-order equivalent circuit model of the battery，the simulation scheme for the battery is carried out，including the table look-up method for the open circuit voltage and iterative algorithm for the dynamic voltage. Finally，a PC tool of the functions above is developed.The specific application example includes the interface design and function layout.The experimental results show that the tool can be used for data analysis and model validation of batteries.

Key words: battery, CAN, second-order equivalent circuit model, open circuit voltage, dynamic voltage, new power system, big data
