A battery module, and a battery pack and a vehicle, each including the battery module. The battery module includes a frame; a plurality of battery cells arranged in the frame; a heat sink in contact with one side of the battery cell; and a cooling fin in contact with the heat sink and in contact with the other side of the battery cell.

A battery system with a passive thermal management system is formed from a plurality of battery cells arranged on a printed circuit board assembly. In some cases, the printed circuit board assembly may include a flexible printed circuit board that is folded along an axis forming an upper and lower portion of the printed circuit board assembly. The thermal management system may include fire-blocking foam members individually attached to each battery cell. The battery cells may be arranged in a grid-like pattern to allow for a spacing arrangement between the battery cells to keep a failing battery cell from negatively affecting an adjacent battery cell. In addition, the flexible printed circuit card may include a fuse for each battery cell to shut off any current flow to a faulty battery cell if it begins to fail causing current flow to exceed beyond a predetermined current limit. The battery system may be a conformal wearable battery.

Abstract: A battery device (3) is provided. The battery device comprises a casing having a plurality of sides (10a-10f) including a bottom side, a top side opposite to said bottom side, two lateral sides, a front side, and a rear side opposite to said front side, wherein the plurality of sides are assembled to form a sealed container, and a battery cell pack (20) located within the sealed container. The casing comprises at least one outlet (31) arranged at at least one of the plurality of sides. The sealed container is configured to prevent heated gases generated upon a malfunction of the battery cell pack from escaping the casing except via the at least one outlet. The battery device further comprises a filter (13) arranged at said at least one outlet for limiting at least flames from escaping the casing, and terminals for connection of the battery device to a load, another battery device or an external power source, arranged at the front side, and wherein said at least one outlet is arranged at the rear side of the casing.

A UV curable dielectric coating is described. The curable coating can include one of more acrylate monomers, a urethane prepolymer, a crosslinker, at least one adhesion promoter, a photoinitiator, and optionally one or more fillers and/or additives. The coating can be used to insulate battery cells and battery packs, such as those used in electric vehicles. The coatings can be easily applied and quickly cured. The cured coatings can have high adhesion strength, even after exposure to wet conditions.

A battery module includes a plurality of battery cell assemblies, each battery cell assembly including at least one battery cell, and a module frame extending in a longitudinal direction of the plurality of battery cell assemblies, the module frame accommodating therein the plurality of battery cell assemblies in a row in the longitudinal direction.
