  • Publication number: 20230268613
    Abstract: A battery device (100) comprising a battery cell pack including a plurality of battery cells (118). The battery device further includes a structure (104) disposed on top of the battery cell pack, the structure including an insulating material (106), and a housing (102), in which the battery cell pack and the structure are arranged. At least an upper surface (110) of the structure has heat- and fire-resistant properties. The insulating material includes a plurality of weakened portions or cuts (112) extending through the insulating material. The structure is arranged such that, in case of burnout of a cell (118a), a ventilation passage (116) is formed over the cell through a weakened portion or cut in the insulating material.

  • Publication number: 20230261314
    Abstract: A battery device (1) is provided. The battery device (1) comprises a casing (10) and a battery cell pack (20) located within the casing (10). The battery device (1) further comprises a flame-retardant encapsulant (30) located within the casing (10) and placed around the battery cell pack (20) to isolate the casing (10) from the battery cell pack (20). The encapsulant (30) forms an envelope comprising an outlet (31) coupled to a ventilation space for ventilation of gases and/or heat generated upon a malfunction of the battery cell pack (20).

  • Publication number: 20230238645
    Abstract: 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.

  • Publication number: 20120085122
    Abstract: A cabinet for refrigerating electronic equipment positioned in a compartment of a cabinet body, said cabinet further being arranged with a cabinet door for closing an access opening to said compartment; at least one partitioning means for partitioning the compartment into at least two sub-compartments, wherein the at least two sub-compartments are in fluid communication; a cooling system arranged in the cabinet door, the cooling system being in fluid communication with the compartment via a fluid outlet and a fluid inlet, the cooling system comprising a fan for discharging cooling fluid via the fluid outlet into at least a first sub-compartment of said at least two sub-compartments and for exhausting fluid via at least a second sub-compartment of said at least two sub-compartments through the fluid inlet; and at least a gasket for abutting, upon closing the cabinet door, the at least one partitioning means to said cabinet door, thereby hindering fluid to pass between the sub-compartments at the cabinet door,

  • Patent number: 6879767
    Abstract: A method and an arrangement in which the assemblies or assembly parts like fiber lengths, opto- and optoelectronic components are transferred between processing modules (46). The assembly parts (22) including a fiber length (23, 24) are arranged on a pallet means (14), which is transferred on a track (16) between the different processing modules. A free end (25, 26) of the optical fiber length is picked up by a robot device (40) and is processed at one of the processing modules. Finally, the robot device holding the fiber end and the pallet means are transferred to another processing module in a common sequence.
