    Abstract: A 12 volt automotive battery system 12 includes a first battery 30 coupled to an electrical system 66, in which the first battery 30 include a first battery chemistry, and a second battery 32 coupled in parallel with the first battery 30 and selectively coupled to the electrical system 66 via a first switch 288, in which the second battery 32 includes a second battery chemistry that has a higher coulombic efficiency than the first battery chemistry. The first switch 288 couples the second battery 32 to the electrical system 66 during regenerative braking to enable the second battery 32 to capture a majority of the power generated during regenerative braking. The 12 volt automotive battery system 12 further includes a variable voltage alternator 64 that outputs a first voltage during regenerative braking to charge the second battery 32 and a second voltage otherwise, in which the first voltage is higher than the second voltage.

    Abstract: A 12-volt automotive battery system includes a first battery coupled to an electrical system, and the first battery includes a first battery chemistry. Further, the 12 volt automotive battery system includes a second battery coupled in parallel with the first battery and selectively coupled to the electrical system via a bi-stable relay. The second battery includes a second battery chemistry that has a higher coulombic efficiency than the first battery chemistry. Additionally, the bi-stable relay 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. Furthermore, the bi-stable relay maintains a coupling of the second battery to the electrical system when the vehicle transitions from a key-on position to a key-off position.

    Abstract: The present disclosure describes a method that includes predicting terminal voltage of a battery module (14) in a vehicle (10) using a battery control module (32). Predicting the terminal voltage includes determining a gassing current of the battery module (14) using a gassing current model, in which the gassing current quantifies terminal current that is not used to charge the battery module (14), 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 (14) using a sensor (34) communicatively coupled to the battery control module (32), and determining a corrected state of the battery module (14) using the battery control module (32) 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.
