Abstract: A traction battery for a vehicle includes a plurality of cells stacked in an array and having a dielectric material surrounding at least a portion of each of the cells. The cells are spaced apart to define a plurality of pockets interleaved with the cells. A manifold is connected to the array and is configured to circulate liquid coolant to each of the pockets such that the coolant directly contacts the dielectric material of each of the cells.

Abstract: An exemplary traction battery assembly includes, among other things, a first portion of an enclosure, a second portion of the enclosure, and a compression limiter. The first portion is overmolded to the compression limiter. An exemplary method includes, among other things, securing a first portion of an enclosure for a traction battery to a second portion, and limiting compression of the first portion during the securing using a compression limiter. The first portion is overmolded to the compression limiter.

Abstract: An exemplary battery assembly includes, among other things, a composite structure of an enclosure. The composite structure provides at least a portion of a coolant channel that carries a coolant. An exemplary battery cooling method includes, among other things, exchanging thermal energy between a coolant and a battery component as the coolant is communicated through a coolant channel. The coolant channel is at least partially established by a composite structure of an enclosure.

Abstract: A vehicle traction battery assembly may include a traction battery and a battery tray. The traction battery is for powering a portion of an electrified vehicle. The battery tray is for supporting the traction battery and defines a coolant channel for distributing coolant in a first direction and a second direction. Battery cells of the traction battery are arranged with the battery tray such that the first direction and the second direction are oriented perpendicular relative to a longitudinal face of one of the battery cells. A plate may be secured to the battery tray without mechanical fasteners to retain coolant within the coolant channel. The plate may be made of aluminum and the battery tray may be die cast aluminum. An inlet channel may extend from an inlet to the coolant channel and may be disposed between a pair of openings defined by the battery tray.

Abstract: A traction battery for a vehicle includes a tray having an outer surface defining an open channel configured to circulate liquid coolant. A plurality of cells are stacked in an array and each has a dielectric material surrounding at least a portion of the cell. The array is disposed on the outer surface and covers the channel such that a side of the array is in direct contact with the coolant during operation.

Abstract: One general aspect includes an electric vehicle (EV) high voltage (HV) battery pack cooling system, including: at least one battery cell positioned in a first compartment of a HV battery pack, where the first compartment is communicatively coupled to a cooling fluid inlet and a cooling fluid outlet positioned on the HV battery pack. The electric vehicle also includes a cooling fluid. The electric vehicle also includes a heat exchanger communicatively coupled to the cooling fluid inlet and the cooling fluid outlet.
