A pouch-type secondary battery includes an electrode assembly including a first electrode plate, a separator, and a second electrode plate; and a pouch film in which the electrode assembly is accommodated, wherein the pouch film includes a first side sealing portion from which a negative electrode lead connected to the electrode assembly protrudes, a second side sealing portion from which a positive electrode lead connected to the electrode assembly protrudes, and an upper sealing portion having both end portions connected to the first and second side sealing portions, and the pouch film includes a folded portion disposed on an end of the first side sealing portion and an end of the second side sealing portion, and folded toward a bottom portion of the pouch film, wherein the folded portion is folded in one direction.

Embodiments included herein are directed towards an apparatus and method for manufacturing an electrical cooling apparatus. The method may include forming a first entirely solid metal plate to generate an enclosure. The method may also include affixing a bottom metal plate to the first entirely solid metal plate, the bottom metal plate may define a channel system. The bottom metal plate may include one or more inlet openings into the channel system, where the one or more inlet openings are configured to allow coolant to enter or exit the channel system.

A heat management apparatus comprises a first heat exchange portion, a second heat exchange portion and a throttle unit, wherein the first heat exchange portion is used for exchanging heat between a refrigerant throttled by the throttle unit, and a cooling liquid; and a first wall of the first heat exchange portion and a second wall of the second heat exchange portion are arranged opposite each other, such that the structure of the heat management apparatus is relatively compact.

The description relates to battery safety and more specifically to containing battery fires. One example can include displacement sub-systems configured to physically separate an affected battery pack from other battery packs. Another example can include a 3D deployable fire curtain configured to automatically deploy around a battery pack to limit the spread of fire between battery packs. A further example can include a media reservoir positioned over a battery pack that is configured to hold non-combustible smothering media. A media retainer can be interposed between the battery pack and the media reservoir and configured to automatically release the non-combustible smothering media into the battery pack support structure when the battery pack experiences a fire.

A two-pass heat exchanger with calibrated bypass is disclosed for cooling heat-generating substrates and/or for heating a heat transfer fluid. The heat exchanger has first and second outer plate walls and an intermediate plate wall located between and spaced from the outer plate walls in the thickness dimension of the heat exchanger, and with inlet and outlet ports at the same end. An input flow passage is defined between the first outer plate wall and the intermediate plate wall, and a return flow passage is defined between the second outer plate wall and the intermediate plate wall. The first and second fluid flow passages are in a U-flow, stacked arrangement. At least one bypass opening extends through the intermediate plate wall between the input and return flow passages, and configured to permit a portion of the heat transfer fluid to bypass portions of the input and return flow passages.
