A method of transfer molding a rotor core stack includes assembling a mandrel and a runner plate between a clamp press and a plunger, determining a final clamp press position, a nominal clamp press position, and a nominal plunger position, calculating a height offset, and calculating a normalized position of the plunger. The plunger moves at a first speed until the plunger contacts a liquid polymer within a reservoir located between the runner plate and the plunger. The plunger moves at a second speed until the plunger reaches the normalized position to extrude the liquid polymer in the reservoir through the runner plate and into the rotor core stack. The plunger speed is controlled to maintain a constant pressure between the plunger and the liquid polymer until the liquid polymer transfer finishes and the plunger stops at a final plunger position.

In one embodiment, a controller of the vehicle estimates a modified driver demand power at an upcoming location on a route of the vehicle, and adjusts the DCC to a fully depressurized state to maximize the fuel efficiency when the modified driver demand power is lower, and pressurizes the DCC to a touch point to reduce the time to engine start when the modified driver demand power is higher. The modified driver demand power may be estimated by the controller by applying multiplication factors to a vehicle-weight-based baseline driver demand power, where the multiplication factors are calculated based on vehicle density of traffic and route characteristics.

Abstract

A battery pack attachment assembly includes a battery pack bracket of an attachment assembly that secures a battery pack to a frame member of a vehicle. The battery pack bracket is removably secured to a battery pack. The battery pack bracket includes a flange that is received within a pocket when the battery pack is secured to the frame member with the attachment assembly.

Abstract

Retention barrier assemblies are provided for traction battery packs. The retention barrier assemblies may be multi-layered and multi-functional sandwich structures that include foam, insulation, a backer plate, and adhesive. The retention barrier assemblies serve numerous functions including but not limited to retaining/holding down battery cells within a cell stack, shielding portions of an enclosure assembly from thermal energy created when one or more battery cells release battery vent gases and/or other effluents during a battery thermal event, and controlling the flow of battery vent byproducts in the event of such a battery thermal event as part of a vent management strategy.

Abstract

Vent path management concepts are provided for traction battery packs. An exemplary traction battery pack may include a vent gas exit path that extends beneath a heat exchanger plate of the traction battery pack. During a battery thermal event, battery vent byproducts released by one or more battery cells of a cell stack of the traction battery pack may be directed through exposed openings of the heat exchanger plate and then into the vent gas exit path. The battery vent byproducts may flow away from high voltage components of the cell stack within the vent gas exit path prior to being expelled from the traction battery pack. The openings of the heat exchanger plate may be sealed by barrier sheets during normal battery operating conditions.
