Abstract: A rechargeable energy storage system (RESS), in accordance with a non-limiting example, includes a first energy storage cell including a first outer surface, a second outer surface, a first lateral side, and a second lateral side. The second lateral side includes a first structural side plate including a first side member extending from the first outer surface toward the second outer surface. A second energy storage cell includes a first outer surface portion, a second outer surface portion, a first lateral side surface, and a second lateral side surface. The first lateral side surface includes a second structural side plate including a second side member extending from the second outer surface portion toward the first outer surface portion. The first side member stacks with the second side member to form an interface joining the first energy storage cell with the second energy storage cell.

Abstract: A framing assembly for a battery module having at least one battery cell stack. The framing assembly includes end plates for forming ends to the battery cell stack, side plates for forming sides to the battery cell stack, and locking plates for securing each end of the side plates to an end plate. The end plates have studs that project from the end plates, the side plates have open-ended slots to receive the studs and pins near the open-ended slots that project from the side plate. The locking plates have stud openings and pin openings that contain the studs and pins when securing the side plates to end plates. Fasteners engage with the studs to retain the locking plates on the studs and pins. Framing assembly maintains compression of the battery cell stacks.

Abstract: A coolant containment system for a battery pack includes a coolant retention container defining a containment space, an inlet connected to the coolant retention container, the inlet connected to an inlet line configured to receive a coolant, an outlet connected to the coolant retention container, the outlet connected to an outlet line, the outlet line configured return a coolant, a drain plug connected to the coolant retention container and in communication with the containment space. The inlet line and the outlet line are disposed entirely within the containment space and any coolant from a leak is retained within the containment space and exits the containment space to an environment outside the battery tray via the drain plug.

Abstract: A battery system includes neighboring first and second groups of battery cells. The battery system also includes a battery system enclosure configured to house each of the first and second groups of battery cells. The battery system additionally includes a vent channel mounted to the battery system enclosure. The vent channel is configured to expel high-temperature gases to external environment separately from each battery cell of the first group of battery cells and divert the high-temperature gases away from other battery cells of the first group of battery cells and from the second group of battery cells. The vent channel minimizes transfer of the high-temperature gases between the battery cells of the first group and from the first group of battery cells to the second group of battery cells and thereby mitigates propagation of a thermal runaway event in the battery system.
