    摘要: A system includes a rechargeable energy storage system (RESS) having an enclosure, battery cells, contactors, a first pair of high-voltage interlock (HVIL) ports, and female blind-mate electrical sockets selectively connected to the battery cells via the contactors. The battery cells and contactors are within the RESS enclosure. The system includes a high-power distribution module (HPDM) having another enclosure, male blind-mate electrical pins, a second pair of HVIL ports engagable with the first pair, ring-terminal connections connected to the blind-mate electrical pins and connectable to high-current components, and HV280 electrical connectors electrically connected to one or more of the male blind-mate electrical pins. The male blind-mate electrical pins insert directly into and engage with the female blind-mate electrical sockets of the RESS enclosure. A vehicle includes the system, a transmission, and an electric machine.

    摘要: A dual-function, combined thermal/structural structure for simultaneously holding and cooling one or more battery cells that are stacked inside of a battery pack. The dual-function structure comprises: (1) a first cooling plate with a first plurality of parallel internal coolant channels; (2) a second cooling plate with a second plurality of parallel internal coolant channels; (3) a first structural side plate; (4) a second structural side plate; and (5) fasteners for joining the first cooling plate, the second cooling plate, the first structural side plate, and the second structural side plate together into an rectangular, box-like, cooled structure. The first and second cooling plates simultaneously structurally support and thermally cool one or more battery cells on at least two opposite sides. Additional horizontal cooling plates can be used to thermally cool and structurally support the underside of each battery cell, thereby providing a 3-sided cooling effect.

    摘要: An electrochemical assembly includes a case defining an interior region, an electrochemical cell, a device, and a pressure relief valve. The electrochemical cell is disposed within the interior region. The device includes a spreader component. The spreader component includes a polymer matrix and an additive embedded in the polymer matrix. The additive includes an endothermic phase change material, a flame retardant material, an intumescent material, or any combination thereof. The device defines a device outlet. The pressure relief valve has a valve inlet fluidly connected to the interior region and a valve outlet fluidly connected to the device. The pressure relief valve is configured to transfer a gas from the interior region to the device when a pressure in the interior region exceeds a predetermined pressure. The spreader component is configured to be in fluid communication with the gas and direct the gas to the device outlet.
