Abstract: A bipolar solid-state battery includes N solid-state battery cells. Each of the N solid-state battery cells includes M solid-state cores each comprising a first current collector, cathode active material, a separator, anode active material, and a second current collector, where N and M are integers greater than one. The M solid-state cores are connected in parallel by connecting the first current collectors of the M solid-state cores in each of the N solid-state battery cells together and by connecting the second current collectors of the M solid-state cores in each of the N solid-state battery cells together. N−1 clad plates including a first side made of a first material and a second side made of a second material. The N−1 clad plates are arranged between adjacent ones of the N solid-state battery cells and the N solid-state battery cells are connected in series by the N−1 clad plates.

Abstract: A vehicle system is provided and includes a modular dynamically allocated capacity storage system (MODACS) and an active management module. The MODACS includes blocks of cells. The active management module is configured to: detect a first state of a first block of cells of the blocks of cells; determine whether a safety fault condition exists with the first block of cells based on the first state of the first block of cells; in response to detecting existence of the safety fault condition, isolate the first block of cells from other ones of the blocks of cells; subsequent to isolating the first block of cells, actively discharge and detect a second state of the first block of cells; and based on the second state, continue isolating the first block of cells or reconnecting the first block of cells such that the first block of cells is no longer isolated.

Abstract: A capacitor-assisted hybrid lithium-ion electrochemical cell assembly includes two positive electrodes having a first polarity, each having at least two electrically conductive tabs disposed on at least one first edge and at least one second edge. Further, two negative electrodes having a second polarity each having at least two electrically conductive tabs disposed on at least one first edge and at least one second edge. At least one of the two positive electrodes or negative electrodes are distinct from one another. The electrically conductive tabs are substantially aligned in the electrochemical cell to respectively define a plurality of positive electrical connectors and a plurality of negative electrical connectors to reduce current density during high power charging and discharging.

Abstract: A battery control system includes T contactor paths connected in parallel between a battery and a load, where T is an integer greater than one. Each of the T contactor paths includes a first contactor and a second contactor connected in series with the first contactor. Each of the T contactor paths includes at least one of a first voltage sensor configured to sense a first voltage between the first contactor and the second contactor; and a current sensor configured to sense current flowing through the first contactor and the second contactor. A second voltage sensor is configured to sense a second voltage at one end of the T contactor paths. A third voltage sensor is configured to sense a third voltage at an opposite end of the T contactor paths.
