Abstract

The invention discloses a method and a device for determining voltage abnormity of a single battery. The method comprises the following steps of acquiring and processing monitoring data of a target vehicle in a preset time period to obtain valid data of the target vehicle in a standing scene; the valid data being processed into a corresponding valid data table, the valid data table comprising multiple rows of data, and each row of data correspondingly comprising voltages corresponding to the multiple battery cells at the same moment; processing the voltage data contained in the valid data table according to a sliding window algorithm to obtain a plurality of voltage difference deviation degrees corresponding to a plurality of moments of a plurality of battery cells; and according to a plurality of voltage difference deviation degrees corresponding to each battery cell, determining whether each battery cell being abnormal in a preset time period. According to the method, a technical problem of low efficiency of the technical means for monitoring consistency of the battery cells of the automobile in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of battery cell voltage, in particular to a method and device for determining abnormal battery cell voltage. Background technique [0002] With the popularity of new energy electric vehicles, the safety of new energy vehicles has become an urgent problem to be solved. [0003] In the existing technology, on the one hand, by improving the production process of the battery cell, the manufacturing accuracy of the battery cell is improved, thereby improving the safety performance of the whole package; Carry out vehicle battery status monitoring and fault warning. [0004] Based on the real-time data uploaded by new energy electric vehicles, the current big data algorithm mainly uploads parameter values ​​based on the maximum voltage of the single cell, the minimum voltage of the single cell, the maximum temperature, and the minimum temperature. [0005] In the existing technology, the change of voltage or temper...
