The present disclosure relates to a modular battery system for use in a variety of motive and non-motive applications. The modular battery system further includes at least one module which is configured and dimensioned for receipt of at least one cell. The at least one cell includes a battery cell for providing energy and a supplementary cell for providing ancillary benefits. One aspect of the disclosure incorporates use of supplementary cells in modules for the purposes of adjusting capacity or voltage, while maintaining the desired weight.

A transport device for lithium batteries in an aircraft, in particular in a hold, includes a container and a lid, lithium batteries being arranged in the container and the lid closing the container during transport of the lithium batteries. A shutoff valve neutralizes electrolyte released by the lithium batteries within the container or conveys the electrolyte to the outside.

A battery sub-packing unit includes at least one battery cell; and a case accommodating the at least one battery cell, wherein the case comprises an end panel on which an electrode tab of the at least one battery cell is fastened to extend into an external space, and having a lower end portion in which a sub-vent hole is formed for communication between the external space and an internal space in which the at least one battery cell is disposed.

An embodiment is directed to a module-to-module power connector configured to form connections between battery modules installed in a battery housing of an energy storage system. The module-to-module power connector includes electrical interfaces and busbar(s) configured to form one or more electrical connections terminals of adjacent battery modules. The busbar(s) is flexibly configured to permit a defined range of movement of the electrical interfaces during insertion of the respective battery modules into respective battery module compartments. The module-to-module power connector may further be arranged inside in a tunnel space, whereby holes are defined in a battery module mounting area housing the battery modules that open into the tunnel space.

An energy storage module includes a plurality of battery cells, each including a vent; a plurality of insulation spacers, at least one of the insulation spacers being located between long side surfaces of each adjacent pair of the battery cells; a cover member including an internal receiving space; a top plate coupled to a top portion of the cover member and including ducts respectively corresponding to the vents of the battery cells, and opening holes respectively corresponding to the insulation spacers; a top cover coupled to a top portion of the top plate and including discharge holes respectively corresponding to the ducts; and an extinguisher sheet located between the top cover and the top plate, configured to emit a fire extinguishing agent at a temperature exceeding a certain temperature, and including opening holes positioned to correspond to the ducts.

A housing for an electrical device such as a battery includes a casing with opposing ends. The casing is made of a composite material such that the housed device is surrounded by composite walls containing intumescent material which protects the outer composite materials from high temperatures generated inside the housing. An end cap is provided having a sandwich structure with a core, configured to evenly distribute compressive pre-load across a battery stack in the housing. A height adjustable end cap is also provided.

A drive battery for a vehicle, in particular a motor vehicle, includes a housing, which has a plurality of partial regions, wherein one or more cell modules are respectively arranged in a first partial region and in a second partial region. A composite component is arranged between the first partial region and the second partial region in order to separate the partial regions. The composite component has a profile element of fiber-reinforced plastic, a foam body of a compressible foam and/or a silicone mat.
