Abstract

The embodiment of the invention provides a data processing method for a power battery and device, which are applied to a power assembly. A battery management system operates in the power assembly; thebattery management system comprises a database; historical battery data are stored in the database, and the historical battery data in the database are acquired; feature sequence data and initial sequence data in the historical battery data are extracted; according to the feature sequence data, a first training input vector and a first training sample vector are generated; the first training input vector and the first training sample vector are adopted to train a preset machine learning model, and a machine learning model after training is acquired; the initial sequence data are inputted to the machine learning model after training to acquire predicted voltage sequence data; and according to the predicted voltage sequence data, the battery capacity information of the power battery is acquired. The cost is reduced, the time is saved, and the problem of much consumed manpower bright by a capacity estimation experiment can be solved.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a data processing method for a power battery and a data processing device for a power battery. Background technique [0002] The power battery is the core component in the field of new energy vehicles. The performance of the power battery directly affects the driving experience of electric vehicles such as power performance, cruising range and safety. The performance of a power battery includes battery capacity, internal resistance, and monomer consistency. Among them, battery capacity, as the most important and intuitive performance measurement index, can directly affect the battery life of electric vehicles. The existing battery capacity estimation methods are mainly divided into the following two methods: the empirical estimation of the capacity fading mode based on the ideal condition experiment, and the black box model based on the battery characterization data and ...
