| Abstract: | In order to monitor the state of the battery pack,to implement the control/query and data read-back of the battery management system(BMS) by communications,the online maintenance platform which can monitor the single battery state roundly is designed in the paper.Moreover,in order to estimate the state of charge(SOC) through updating the parameters and maintaining the battery of the BMS.The practical application indicates that the platform eases the workload and raises the estimating accuracy of the SOC. |
