Abstract
Techniques for estimating a battery state of a battery include receiving a present battery measurement associated with an unknown battery state and a calibration measurement associated with a known calibration condition. An input set is generated based on the present battery measurement and the calibration measurement. The input set is inputted into a battery state model to receive an output of the battery state model. The output includes a present battery state estimation for the unknown battery state.

A method for estimating a battery state of a battery, the method comprising:
- receiving a present battery measurement associated with an unknown battery state;
- receiving a calibration measurement associated with a known calibration condition;
- generating an input set based on the present battery measurement and the calibration measurement;
- inputting the input set into a battery state model;
- and
- receiving an output of the battery state model, wherein the output includes a present battery state estimation for the unknown battery state.
A system comprising:
- at least one hardware processor;
- and
- at least one memory storing instructions that, when executed by the at least one hardware processor, cause the at least one hardware processor to perform operations comprising:
- receiving a present battery measurement associated with an unknown battery state;
- receiving a calibration measurement associated with a known calibration condition;
- generating an input set based on the present battery measurement and the calibration measurement;
- inputting the input set into a battery state model;
- and
- receiving an output of the battery state model, wherein the output includes a present battery state estimation for the unknown battery state.
