  • Patent number: 11705604
    Abstract: 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.
