    Abstract: Embodiments describe a battery system that includes a first battery module coupled to a regenerative braking system and a control module that controls operation of the battery system by: determining a predicted driving pattern over a prediction horizon using a driving pattern recognition model based in part on a battery current and a previous driving pattern; determining a predicted battery resistance of the first battery module over the prediction horizon using a recursive battery model based in part on the predicted driving pattern, the battery current, a present bus voltage, and a previous bus voltage; determining a target trajectory of a battery temperature of the first battery module over a control horizon using an objective function; and controlling magnitude and duration of electrical power supplied from the regenerative such that a predicted trajectory of the battery temperature is guided toward the target trajectory of the battery temperature during the control horizon.

    Abstract: A battery module includes a power assembly including a first battery cell and a second battery cell in a stacked orientation relative to each other, wherein the first battery cell comprises a first tab electrode extending therefrom, and wherein the second battery cell comprises a second tab electrode extending therefrom. The battery module also includes an interconnect assembly configured to facilitate electrically coupling the first tab electrode with the second tab electrode with the first and second battery cells in the stacked orientation. The interconnect assembly includes a coupling structure about which the first and second tab electrodes at least partially conform. In addition, the interconnect assembly includes a clamp disposed about the coupling structure and the first and second tab electrodes such that the first and second tab electrodes are secured in electrical communication.

    Abstract: A battery system includes a battery module, a thermal management system, and a battery system controller. The controller is configured to receive data indicative of first operational conditions of the battery module and of second operational conditions of the thermal management system, determine a desired change to the first operational conditions of the battery module by determining an amount of power available to the thermal management system and to the battery module from one or more power sources, and to enable, to effect the desired change to the first operational conditions, the one or more power sources to provide a first quantity of power to the thermal management system and a second quantity of power to the battery module, and the thermal management system to heat or to cool the battery module to a calculated extent.

    Abstract: A system includes a battery cell having an internal heat fin and a first electrically insulating layer disposed over at least a portion of a single side of the internal heat fin. The battery cell includes an electrochemical stack disposed above the first insulating layer and the internal heat fin in a stack. The battery cell also includes a pouch material film configured to hermetically seal with one side of the internal heat fin or the first insulating layer about the electrochemical stack such that the internal heat fin forms an outer boundary of the battery cell. The pouch material film includes a metallic foil layer disposed between a second electrically insulating layer and a third electrically insulating layer.

    Abstract: A battery module includes active material disposed in layers to form a generally planar electrochemical cell with an upper surface, a lower surface, and side surfaces. The battery also includes electrodes extending out of the electrochemical cell, and a frame disposed about the active material such that edges of the frame surround the side surfaces of the active material and the electrodes extend beyond the frame. The battery further includes an upper layer of pouch material disposed over the upper surface of the active material and an upper surface of the frame, and a lower layer of pouch material disposed over the lower surface of the active material and a lower surface of the frame. The upper layer of pouch material and the lower layer of pouch material function to provide a seal that seals the active material within the frame.

    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.
