Abstract: A battery assembly includes a battery pan and battery cells. The battery cells are supported within the battery pan and disposed in a plurality of rows. The battery assembly includes a plurality of vents, and each of the plurality of vents is defined by a floor of the battery pan, support members, and a battery tray. Each vent extends a length of each row. An endcap is coupled to the structural plates of the battery pan. The endcap includes a plurality of apertures, a baffle, and a vent channel. The baffle has a baffle wall disposed opposite the plurality of apertures. The baffle wall extends to the ceiling and the floor of the elongated body. The vent channel extends along the baffle and is configured to carry vent gas. The battery assembly also includes a pack vent configured to exhaust the vent gas from the endcap.

Abstract: A vehicle assist system includes an imager coupled to a vehicle body. The imager is configured to capture a vehicle environment, and a GPS processor is configured to detect a geographical location of a vehicle. The vehicle assist system also includes a controller that stores vehicle data and a coastdown procedure. The controller is communicatively coupled to the imager and the GPS processor and is configured to detect a trigger event. In response to the trigger event, the controller is configured to execute the coastdown procedure based on the vehicle data, the vehicle environment from the imager, and the geographical location of the vehicle.
