Abstract
A battery management system (BMS) for a vehicle includes a module for estimating the state of a rechargeable battery, such as its state of charge, in real time. The module includes a learning model for predicting the state of a battery based on the vehicle's usage and related factors unique to the vehicle, in addition to a sensed voltage, current and temperature of a battery.

-21. (canceled)
A method, comprising:
- providing a trained machine learning battery model;
- inputting, into the trained machine learning battery model, obtained data comprising a measured voltage, current, impedance, pressure, temperature of at least one series string of battery cells, or a combination thereof;
- inputting at least one battery type;
- using the trained machine learning battery model to predict a battery state;
- and
- producing an output based on the predicted battery state.
