摘要： A battery module (102) is contained in a battery pack (100) and includes plural cells (118), a first cell holder (112), a second cell holder (114), and a current collector (116). The first cell holder (112) and the second cell holder (114) each have plural pockets to retain the cells (118). The first cell holder (112) and the second cell holder (114) are assembled to form a manifold to partially submerge the cells (118) within fluid. In addition, an interface (130) between a curved surface of the cells (118) and a curved surface of the pockets of at least one of the first cell holder (112) and the second cell holder (114) is sealed using a sealant. Further, the interface between the first cell holder (112) and the second cell holder (114) is sealed.

摘要： An apparatus may include a material with different portions having different densities. In one or more implementations, the material includes beads. Despite the different densities, the material is the same for both densities, thus the material may include the same chemistry but with different densities. Based on using a material of the same chemistry, the beads may fuse together. The apparatus may take the form of a potting structure for battery cells. Alternatively, the apparatus may take the form of a battery subassembly for various battery applications.

摘要： A multi-cell rechargeable energy storage system (RESS) includes an enclosure having a tray and a cover with battery cells mounted to the tray and a structural senseline assembly having a busbar subassembly for connecting the battery cells. The senseline assembly also includes a sensing device for detecting operation of the battery cell(s) and a sensing circuit connected to the busbar subassembly and to the sensing device for communicating electrical signals therefrom to an external controller. The senseline assembly additionally includes a first interconnect board (ICB) disposed between the battery cells and the busbar subassembly to position the sensing circuit, the busbar subassembly, and the sensing device, and electrically isolate the busbar subassembly from the cells. The senseline assembly further includes a second ICB disposed between the cover and the busbar subassembly and structurally connecting the cover to the first ICB to transmit physical forces between the cover and the tray.

摘要： A battery module includes a battery pack and a first conductive member. The first conductive member includes a first connecting part, a first functional part, and a second connecting part located at a side of the battery pack and connected in sequence, and the first connecting part is electrically connected to the battery pack. The first functional part includes a first part and a first protrusion. The first part connects the first connecting part and the second connecting part. The first protrusion extends from the first connecting part towards the second connecting part along a second direction. The first protrusion is apart from both the first part and the second connecting part, enabling the first functional part to be more easily blown.
