    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. As such, this may provide more efficient use of energy.

    Abstract: A 12 volt automotive battery system includes a first battery coupled to an electrical system, in which the first battery include a first battery chemistry, and a second battery coupled in parallel with the first battery and selectively coupled to the electrical system via a first switch, in which the second battery includes a second battery chemistry that has a higher coulombic efficiency than the first battery chemistry. The first switch couples the second battery to the electrical system during regenerative braking to enable the second battery to capture a majority of the power generated during regenerative braking. The 12 volt automotive battery system further includes a variable voltage alternator that outputs a first voltage during regenerative braking to charge the second battery and a second voltage otherwise, in which the first voltage is higher than the second voltage.
