Abstract
A computer-implemented method for predicting a quality of a battery includes receiving a first battery measurement data for a first duration of soaking the battery, the first duration shorter than or equal to the soaking. The method further includes computing a plurality of features based on the first battery measurement data. The method further includes predicting, based on the plurality of features, a state of the battery after completion of the soaking. The method further includes outputting suitability of the quality of the battery based on the state of the battery as predicted.
Claims20
A computer-implemented method for predicting a quality of a battery, the computer-implemented method comprising:
- receiving a first battery measurement data for a first duration of soaking the battery, the first duration shorter than or equal to the soaking;
- computing a plurality of features based on the first battery measurement data;
- predicting, based on the plurality of features, a state of the battery after completion of the soaking;
- and
- outputting suitability of the quality of the battery based on the state of the battery as predicted.
A system for predicting a quality of a battery, the system comprising:
- a processor comprising a plurality of processing cores;
- a plurality of sensors coupled with the processor and the battery, wherein the processor is configured to receive a first battery measurement data for a first duration during a soaking of the battery, and predicting the quality of the battery after completion of the soaking by performing a method comprising:
- computing a plurality of features based on the first battery measurement data;
- predicting, based on the plurality of features, a state of the battery after completion of the soaking;
- and
- outputting suitability of the quality of the battery based on the state of the battery as predicted.
A computer program product comprising a non-transitory memory device that has one or more computer executable instructions stored thereon, and which are executable by one or more processing units to perform a method for predicting a quality of a battery, the method comprising:
- receiving a first battery measurement data for a first duration of soaking the battery;
- computing a plurality of features based on the first battery measurement data;
- predicting, based on the plurality of features, a state of the battery after completion of the soaking;
- and
- outputting suitability of the quality of the battery based on the state of the battery as predicted.
