Abstract: The present disclosure describes a method that includes predicting terminal voltage of a battery module in a vehicle using a battery control module. Predicting the terminal voltage includes determining a gassing current of the battery module using a gassing current model, in which the gassing current quantifies terminal current that is not used to charge the battery module, and calculating the predicted terminal voltage based at least in part on a measurement model and the determined gassing current. The method also includes measuring terminal voltage of the battery module using a sensor communicatively coupled to the battery control module, and determining a corrected state of the battery module using the battery control module by minimizing a difference between the predicted terminal voltage and the measured terminal voltage. In other words, the corrected state of the battery (e.g., corrected state of charge) may be more accurately determined using the measurement model and the gassing current model.

Abstract: A system for providing power to a power network includes an energy storage device connected to the power network, a sensor connected with the energy storage device for measuring a state of the energy storage device during a rest period, which corresponds to a time span during which a current through the energy storage device is reduced to a level that enables an estimation of a state of the energy storage device. The system further includes a controller connected to the sensor for measuring a state of the energy storage device. The controller selectively establishes rest periods for the energy storage device. The rest periods are established by optimizing between minimization of disruption to normal operation and a need to update a measurement of the state of the energy storage device.

The transfer of the electrical energy serves to reduce the electrical energy stored in the first energy storage device thereby enabling the first energy storage device to receive from the regenerative power device when the predicted regenerative power event occurs an amount of the electrical regenerative energy.
