Abstract: An exemplary battery assembly includes first and second pieces of an enclosure, a flange of the first piece, and a clamping device compressing together the flange and a portion of the second piece to seal an interface. The clamping device has an interior area that receives the flange such that the clamping device extends continuously from a first side, about an outer edge, to an opposite, second side of the flange. An exemplary battery enclosure securing method includes receiving a flange of a first enclosure piece within an open area of a clamping device while the clamping device compresses together the flange and a portion of a second enclosure piece. The clamping device extends continuously from a first side of the flange, about an outer edge of the flange, to an opposite, second side of the flange when the flange is received within the open area.

Abstract: A battery pack includes a heat exchanger plate assembly that includes a plate body, a retention cradle protruding outwardly from the plate body, and a coolant conduit secured to the plate body by the retention device. The coolant conduit may snap into the retention cradle to secure the coolant conduit to the plate body.

Abstract: A battery pack includes an enclosure assembly including a tray and a cover system secured relative to the tray. The cover system includes a first cover and a second cover that overlap one another. At least one of the first cover and the second cover includes a stepped design. Another battery pack includes an insert received within a tray and adapted to establish a first compartment and a second compartment within the tray. A first cover is positioned to cover the first compartment and a second cover is positioned to cover the second compartment.

Abstract: A vehicle includes an engine, a traction battery, a generator coupled to the engine and battery, and a controller. The controller may be configured to, in response to a current flowing from a battery charge station to the battery being less than a maximum charge current, a selection of a fast charge mode, and a temperature of the engine being less than a predetermined temperature, operate the engine to generate a supplemental current to charge the battery.

Abstract: A vehicle includes an electric machine arranged to exchange power with a traction battery. The vehicle also includes a thermal conditioning system for influencing a battery temperature and a controller programmed to schedule battery charging. In response to a temperature of the traction battery exceeding a threshold, the controller issues a command to operate the thermal conditioning system prior to a scheduled battery charge to achieve a predetermined battery temperature at a start of battery charging.

Abstract: A vehicle includes an engine arranged to output torque and an electric machine arranged to apply a reaction torque against engine output torque to generate power for charging a traction battery. The vehicle also includes a controller programmed to issue a command to adjust the engine output torque and an output speed corresponding to a predetermined optimal brake specific fuel consumption while providing power to charge the fraction battery, satisfy an accessory power demand, and propel the vehicle.
