Abstract: This disclosure details exemplary traction battery pack venting systems for use in electrified vehicles. An exemplary traction battery pack system may include a venting system having one or more vent ducts for expelling battery vent byproducts from a battery pack. The vent ducts may include a thermal barrier configured to block heat emitted by the battery vent byproducts during cell venting events. In some embodiments, the thermal barrier includes a thermal barrier coating. In other embodiments, the thermal barrier includes both a thermal barrier coating and a thermal barrier layer. In still other embodiments, a second thermal barrier may be applied to vehicle components located near the battery pack for improving the thermal barrier properties.

Abstract: A controller, during DC fast charge of a traction battery, commands a DC charge current to have a magnitude less than a predefined value and responsive to magnitudes of resulting voltage drop data for a fast charge contactor connected between a charge port and main contactor being less than a first threshold value, commands the DC charge current to have a magnitude at a target high value.

Abstract: Electrified vehicles may be powered by traction battery packs. An exemplary traction battery pack may include an enclosure assembly having a tray and a cover. One or more hinged locking plate assemblies may be utilized to secure the cover to the tray of the enclosure assembly. The hinged locking plate assemblies may be configured to exert a clamping or compression force across an interface between the cover and the tray, thereby enhancing retention and providing a leak-proof joint.

Abstract: A modular battery and power control system provides a range of electrical power to high-voltage and low-voltage power demand systems in a hybrid vehicle. The modular battery and power control system provides a single high-voltage modular battery pack that is selectively connected to high-voltage and low-voltage demand systems by a switch system. The switch system is controlled by a voltage controller module which monitors power demand and charge states of the electrical system and determines the switch positions to effect the indicated electrical demands of the hybrid vehicle.

Abstract: A vehicle having: vehicle structure including a pair of opposed sides and a rear, with a floor extending horizontally between the sides and rear; a battery-pack mounted above the floor; a fan assembly having a housing with a motor mounted therein directly behind the battery-pack, with the housing including a pair of flanges having U-slots with slot openings facing downward; and fasteners extending horizontally through the U-slots and secured to the battery-pack.

Abstract: A modular battery and power control system provides a range of electrical power to high voltage and low voltage power demand systems in a hybrid vehicle. The modular battery and power control system provides a dual voltage modular battery pack that provides both a high voltage output and a low voltage output. The modular battery pack is selectively connected to high voltage and low voltage demand systems by a switch system. The switch system is controlled by an ignition switch module which determines the electrical demands of the hybrid vehicle.

Abstract: A gaseous fuel management system for an automotive vehicle includes at least one gas sensor for detecting the presence of gaseous fuel outside of the confines of the vehicle's fuel storage tank, fuel lines, and prime mover. In the event that fugitive gas is detected and the concentration exceeds a predetermined threshold, the fuel supply to the vehicle's prime mover will be shut off and, if so equipped, the vehicle may then be operated in a battery power mode for the convenience of the driver.
