The invention relates to a housing for a cell stack of a battery, comprising: an integral frame from accommodating the cell stack, wherein the frame surrounds at least three end faces of a cell stack which is accommodated in the housing, and at least one electrically conductive connecting element for establishing an electrical connection between an external connection and a cell stack which is accommodated in the housing is integrated in the frame; and a cover for covering sides, in particular all sides, of a cell stack which is received in the housing, which sides are not surrounded by the frame.

A battery pack is provided. The battery pack includes first and second temperature sensors that are disposed in first and second interior spaces, respectively. The first temperature sensor generates a first signal indicative of a first temperature level of the battery cell. The second temperature sensor generates a second signal indicative of a second temperature level of the DC-DC voltage converter. The battery pack further includes a microprocessor that determines a first desired operational speed value of the electric fan based on the first temperature level, and a second desired operational speed value of the electric fan based on the second temperature level. The microprocessor selects the first desired operational speed value if the first desired operational speed value is greater than the second desired operational speed value.

The present invention relates to a battery housing for receiving one or more battery modules, in particular for an electrically powered vehicle or a vehicle having a hybrid drive, comprising a box having a frame and a base, which provides an interior space for receiving the battery module or modules, at least one mounting support which is connected at least in certain portions, on that side of the frame which faces away from the interior space, to the frame of the box and which serves for the releasable connection of the battery housing to a vehicle, and a cover for closing the box, wherein the frame, the base, the mounting support or the cover of the battery housing is manufactured from a steel sheet which has a microstructure comprising ferrite and martensite and which is provided with a zinc-based coat on one or both sides.

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 battery module includes at least one cell group, and a heat dissipating member coupled to one side of the at least one cell group to externally dissipate heat generated in the at least one cell group, wherein the at least one cell group includes at least one battery cell stack, a flame retardant cover coupled to the battery cell stack to encase both side surfaces and an upper portion of the battery cell stack, and a flame retardant member disposed between an upper surface of the battery cell stack and the flame retardant cover and formed of a porous material.

A battery pack includes a plurality of non-aqueous electrolyte single cells, each single cell being such that a rolled electrode body is housed in a flat case; a plurality of spacers; and a banding member. The rolled electrode body includes a collector portion, and a power generating portion. Each spacer has a recessed portion provided on at least one surface that faces the adjacent single cell. A side plate of the case that faces the surface of the spacer on which the recessed portion is provided includes a thick portion that contacts the power generating portion of the rolled electrode body inside the case, and a thin portion that is thinner than the thick portion and is continuous with both sides of the thick portion in the rolling axis direction. The surface of the spacer on which the recessed portion is provided abuts against only the thick portion.

An energy storage apparatus includes an outer case, and an energy storage device housed in an inside of the outer case. The outer case includes a ventilation chamber which makes the inside and an outside of the outer case communicate with each other. The ventilation chamber includes a front wall in which a through hole communicating with the outside is formed, a back wall disposed at a position where the back wall opposedly faces the front wall, a first wall disposed between the through hole and the back wall, and a first side wall disposed in an extending manner along a first direction which intersects with the front wall with a gap formed between the first side wall and the first wall. The gap is formed over a distance from the front wall to the back wall along the first direction.

A battery pack thermal management assembly is provided for use with an electric vehicle in which the battery pack is sealed and mounted under the car. The batteries contained within the battery pack are thermally coupled via a layer of thermally conductive material to the interior surface of the pack's upper enclosure panel. A shaped conduit panel is attached to the exterior surface of the pack's upper enclosure panel. A cooling panel structure containing a coolant channel is defined by the enclosure panel's exterior surface and the conduit panel's interior surface.
