Abstract: A battery cell includes a pouch, an electrolyte material, positive and negative electrodes, and one or more heat conducting members. The pouch has an inner surface defining an internal volume, within which is contained the electrolyte material. The electrodes form current collectors that are positioned within the internal volume of the pouch. The electrode terminals are connected to a respective one of the positive and negative electrodes. Each heat conducting member is in thermal communication with a respective electrode terminal fully within the internal volume of the pouch, and extends between the electrodes and the inner surface of the pouch. The heat conducting members form a parallel heat transfer path within the battery cell. A battery pack includes a housing containing multiple such battery cells.

Abstract: Systems, methods and a cooling module are described. The cooling module is configured to directly cool the plurality of battery cell tabs. The cooling module includes a generally prismatic isolation sheet contacting the battery cell tabs along a common plane and a heat exchanger The heat exchanger includes a metallic portion defining an open cavity and a lightweight portion joined to the metallic portion to define a unitary flow assembly. The metallic portion includes an outer planar surface engaging the second planar surface. The lightweight portion is formed from a thermally conductive plastic material and includes baffles integrally formed with and extending therefrom. The plurality of baffles engage an interior surface of the metallic portion to thereby define a serpentine path for the cooling fluid.

Abstract: A hybrid powertrain system includes a method for managing electrical charging of a DC power source, which includes determining an initial charge-sustaining SOC setpoint and an initial charge-termination SOC setpoint. The DC power source is dynamically monitored. An adjustment to a charge-sustaining SOC setpoint is determined based upon the ambient temperature, the device temperature and the SOC of the DC power source, and an updated charge-sustaining SOC setpoint is determined based upon the adjustment to the charge-sustaining SOC setpoint and the initial charge-sustaining SOC setpoint. An electric energy equalization factor α is determined, and an updated charge termination SOC setpoint can be determined based upon the electric energy equalization factor α, the updated charge-sustaining SOC setpoint and the initial charge-sustaining SOC setpoint. Charging of the DC power source is controlled based upon the updated charge-termination SOC setpoint.

Abstract: Disclosed are joint active thermal management (ATM) systems for electric-drive vehicles, control logic for operating such ATM systems, and electric-drive vehicles equipped with a joint ATM system for heating/cooling the powertrain's drive unit (DU) section, power electronics (PE) section, and rechargeable energy storage system (RESS) section. A disclosed active thermal management system includes a first coolant loop with fluid conduits fluidly connecting a first electronic heat exchanger and a first pump with the DU and PE sections. The ATM system also includes a second coolant loop with fluid conduits fluidly connecting a second electronic heat exchanger and a second pump with the RESS section. A coolant-to-coolant heat exchanger, which is fluidly connected to the first and second coolant loops, is operable to selectively transfer heat between the coolant fluid circulating in the first set of fluid conduits and the coolant fluid circulating in the second set of fluid conduits.

Abstract: A system for fast charging an electric vehicle includes a power plug, a charger, a stationary battery, a DC/DC converter, at least one DC fast charge connector and a control unit. The power plug may be a plug which is operatively configured to engage with a standard 120V power source or a 240V power source. The charger may be a unidirectional charger or a bidirectional charger. The DC fast charge connector is adapted to be removably affixed to an electric vehicle. The control unit is in communication with at least two of the charger, the DC/DC converter, the stationary battery, and the DC fast charge connector to provide fast charge to an electric vehicle.
