The invention discloses an application algorithm of a battery online protector. The application algorithm comprises the following steps: S1, collecting an instantaneous voltage value of each detection monomer at each moment and a and b at corresponding moments to establish a training set; s2, establishing a neural network prediction model of the predicted value of the instantaneous voltage value at the next moment; s3, establishing a value neural network prediction model; s4, inputting the voltage value at the current moment into the neural network prediction model established in the S2 to obtain a predicted value of the instantaneous voltage at the next moment; and S5, inputting the instantaneous voltage predicted value of each detection monomer obtained in the step S4 and the average value of the instantaneous voltage predicted values of all the detection monomers into the neural network prediction model established in the step S3, and judging whether the detection monomer at the next moment needs to be subjected to equalization operation or not. According to the method, the neural network prediction model is adopted to intelligently predict the instantaneous voltage value and the threshold value, and manual parameter adjustment is not needed, so that the online protector can quickly make a charging and discharging decision.
Description
technical field [0001] The invention relates to the technical field of battery protection, in particular to an application algorithm of a battery online protector. Background technique [0002] The equalization algorithm of the traditional battery online protector adopts the strategy of keeping the equalization threshold constant. During the charging process, this method has a low charging saturation of the battery pack. When the overcharge threshold is reached, other monomers may be far from saturated. If the equalization opening threshold is set too small, it will greatly affect the charging efficiency of the battery pack and prolong the charging time. Manually adjusting the threshold parameters will greatly improve the threshold calculation. The time is not conducive to the battery protector to make a quick decision. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide an ...
