| Abstract: | For the imbalanced problems in the suspension phase of lithium iron phosphate battery pack,through the fitting equation of the open circuit voltage of the battery cell and the SOC,using the highest voltage in the battery pack,a dynamic threshold for judging the imbalance of the battery pack was obtained,and a balanced control strategy was established for the realization of the balancing process.Finally,the balancing management model was built on the MATLAB/Simulink software platform. |
