Abstract
A system or method for determining a battery state can include generating a set of models based on a measured response of a plurality of batteries to an applied load, measuring battery properties of a battery, and using a state estimator to determine a battery state associated with a battery.
Claims21
A method comprising:
- for each battery of a plurality of batteries:
- applying a load profile to the respective battery;
- and
- characterizing a response of the respective battery to the applied load;
- generating a set of models based on the responses, wherein each model comprises at least one of:
- a thermal model;
- an electrochemical model;
- or
- a heat generation model;
- validating a model of the set of models;
- measuring battery properties of a second battery using a sensor;
- and
- using a state estimator to determine a state of the second battery based on the battery properties and the validated model.

A method for estimating a battery state of a battery comprising:
- generating a set of models based on a measured response of a plurality of batteries to applied loads;
- selecting a model from the set of models based on at least one of:
- an application in which the battery is used;
- a battery property of the battery;
- a target accuracy of the battery state;
- or
- a processor bandwidth;
- and
- determining the battery state using a state estimator running the selected model.
