Abstract: A traction battery assembly includes, among other things, a plurality of battery cells disposed along an axis, an endplate at an axial end of the plurality of battery cells, and a corrugated area of the endplate. The corrugated area has a plurality of corrugations that flatten to accommodate expansion of the plurality of battery cells along the axis.

Abstract: A vehicle having an engine, a battery, and an electric machine configured to propel the vehicle and selectively coupled to the engine to start the engine includes a controller configured to prompt for input to activate a cold weather mode in response to an expected ambient temperature to be below a first temperature threshold for a time period during which a subsequent engine start is anticipated, and to operate the engine and electric machine to maintain a state of charge (SOC) of the battery above a first SOC threshold in response to activation of the cold weather mode, and a second SOC threshold lower than the first SOC threshold otherwise.

Abstract: A vehicle includes an electric machine, a battery, an electrical circuit, an overcharge limit device, and a controller. The electric machine is configured to propel the vehicle. The battery has a plurality of cells and is configured to provide electrical power to the electric machine. The electrical circuit is configured to deliver the electrical power from the battery to the electric machine. The overcharge limit device is configured to individually disconnect each of the plurality cells from the circuit in response to an internal pressure of a respective cell exceeding a pressure threshold. The controller is programmed to, in response to detecting a first set of parameters that are indicative of a first of the cells being disconnected from the electrical circuit via the overcharge limit device, discontinue control the first of the cells.
