摘要： The power storage device structure according to the present invention includes a power storage device and a casing that encloses the power storage device with a gap therebetween, and has a structure in which a molded body containing an acrylic resin or a molded body containing a copolymer of a monomer used for polymerization of an acrylic resin and another monomer is placed in the gap between the power storage device and the casing. The molded body is preferably in the form of a film, sheet, or plate. With such a power storage device structure, it is possible to reduce the risk of ignition in the event of an abnormality such as damage to a power storage device, particularly to a power storage device stack in which multiple power storage devices are stacked, or overcharge.

摘要： The present disclosure relates to a battery assembly for a vehicle such as an electric vehicle or a hybrid electric vehicle, and to methods associated with such an assembly. As disclosed, there is provided a battery assembly for a vehicle, the assembly having a housing, the housing for containing a coolant fluid and at least one battery cell to be cooled by said coolant fluid, the assembly further having a first container volume having a lower portion in fluid communication with an upper portion of the housing, wherein the first container volume has a smaller cross-sectional area in a horizontal plane than that of the housing, and the assembly further having a second container volume having a lower portion in fluid communication with an upper portion of the first container volume. The disclosed battery assembly provides improved battery performance by virtue of improved cell temperature management, particularly when packaging is constrained.

摘要： An extruded hollow plate and an electric vehicle battery casing formed by combining the extruded hollow plates. The extruded hollow plate has a plate-shaped body having a constant cross-section, a cavity is provided inside the plate-shaped body, a protrusion and/or a groove is provided at an end of the body, the protrusion is bent downward, the groove opens upwards as a hook, and the arc surfaces forming the protrusion and the groove each comprise at least two involute surfaces. Compared with the existing battery box manufacturing process of friction stir welding, the combining and bonding connection manner has the significant advantages of rapid production speed, a low device cost, high flatness, etc.

摘要： A cell module includes a plurality of cylindrical batteries and a holder composed by arranging each of cylindrical batteries in a parallel posture. The holder includes: a holder body having holding spaces for arranging cylindrical batteries at fixed positions; and a sub holder stacked on the holder body. The holder body has stopper portions deformed toward surfaces of cylindrical batteries arranged in holding spaces. The sub holder has push rods that push out stopper portions to cylindrical batteries in a state of being coupled to the holder body. In a state in which the sub holder is coupled to the holder body, in the cell module, the push rods thrust stopper portions against cylindrical batteries, and press the surfaces of cylindrical batteries arranged in holding spaces.

摘要： A traction battery module for a vehicle, with a battery housing, the battery housing having a preferably extruded housing part with hollow chambers formed in it, which extend alongside one another along a central longitudinal direction and are open at the ends. The hollow chambers respectively define a cooling channel. At least one cooling connection adapter is provided, having a non-circular outer circumferential surface in an insertion portion and having been introduced or pressed at the end into one of the hollow chambers with an inner circumferential surface corresponding to the outer circumferential surface of the insertion portion. A pressing engagement is formed, at least in certain portions, between the outer circumferential surface and the inner circumferential surface.
