Difference value differential based lithium iron phosphate power battery power loading capacity dynamic prediction method

The invention relates to a difference value differential based lithium iron phosphate power battery power loading capacity dynamic prediction method which mainly comprises the following steps: (1), performing measurement and acquisition of data including battery voltage difference value, current difference value, and temperature difference value, and establishing data dependency models in different active sections; (2), constructing data sheets, establishing a dynamic time-variable three quantities based algebraic interpolation function, analyzing an interpolation remainder, and analyzing the differential features of the interpolation remainder; and (3), analyzing the dependency, and revising each battery power loading capacity dynamic model factor in a battery pack. According to the difference value differential based lithium iron phosphate power battery power loading capacity dynamic prediction method, not only are the influences over the battery power loading capacity by the voltage, the current and the stability of a single power battery cell considered, but also influences over the power loading capacity when the batteries dynamically work by the voltage difference value, the current difference value and the temperature difference value of the power battery within a unit time and the autocorrelation and the cross correlation of the difference value variable quantity among the single battery cells of the battery pack are considered, and the discrete value differential analysis method is applied to accurately predict the power loading capacity when the single battery cells of the power battery pack work dynamically.
