BATTERY ENCLOSURE

A battery enclosure and method for manufacturing the same from organosheet materials. The battery enclosure includes a top cover with crossbeams integrated therein by overmolding that secures to a bottom panel to enclose a space for containing components of a battery. The bottom panel includes overmolded structural ribs to provide strength and rigidity to the bottom panel. An outer cover removably secure the top cover to the bottom panel and includes a honeycomb structure to crush upon impact and protect the battery components. The method comprises forming each of the components of the battery enclosure from a mixture of organosheets, reinforcing members, and overmolded elements to reduce the weight and complexity of manufacturing for the battery enclosure.

Battery module with fireproof and fire-extinguishing components

The present disclosure relates to a battery module including at least one battery unit array structure, an upper cover, a lower cover and a fireproof component disposed vertically. Each battery unit array structure includes a plurality of battery units and a plurality of busbars electrically connected to the plurality of battery units. The battery unit array structure is disposed between the upper cover and the lower cover. Each battery unit of each battery unit array structure is provided with a vent facing towards the fireproof component. Different from the related art, when thermal runaway occurs in a battery unit according to the present disclosure, flame and high-temperature particles ejected from a vent of a battery unit are blocked by the fireproof component from burning adjacent battery units, thereby preventing the thermal runaway in the other battery units from being triggered by the existing thermal runaway.

Battery pack exhaust duct and battery pack

A battery pack exhaust duct includes a guide tube, an exhaust inlet, an exhaust outlet, and exhaust guide components. The exhaust guide components include first and second exhaust guide components. Each of the exhaust guide components has a first part and a second part. The first part has a first end that is nearer to the interior surface of the guide tube. The first part extends away from the interior surface, and toward the exhaust inlet. The second part has a first end that is nearer to the first part. The second part extends toward the interior surface. The second part has a second end that is apart from the interior surface. The second end of the second part of the first exhaust guide component and the second end of the second part of the second exhaust guide component are displaced along axis X along which the guide tube extends.

Air Displacer, Traction Battery, Production Method and Motor Vehicle
20230014625 · 2023-01-19 ·

An air displacer for a traction battery of a motor vehicle is configured such that, in the installed state in a battery housing of the traction battery, it at least partially fills a free volume in the battery housing and thereby at least partially displaces air in the battery housing in the event of heat generation inside the housing. The air displacer includes a vacuum bag; a foam that can be expanded using air, which is arranged in the vacuum bag; and a manually opening air inlet point. The air displacer can be transferred from an initial state in which the vacuum bag is evacuated in the closed state of the air inlet point and the foam in the vacuum bag is compressed, into an end state provided for the installed state in which air flows through the vacuum bag by manually opening the air inlet point and the foam is thereby expanded.
