Abstract:
This invention relates to an intelligent information process technology field for electromotive cars characterizing in including the following steps: carrying out compound pulse experiment of a cell set to get its charge/discharge voltage curves, getting the parameter of a standard cell model based on said experiment data, picking up the Ohmic internal resistance-SOC curve of the standard celll model and an open-circuit voltage-SOC curve and computing the abserved matrix, setting up a complete Kallman filtering SOC estimation algorithm based on the model and a cell management system to compute the SOC value of each point with the SOC estimation algorithm.
