Abstract

A battery device is disclosed. In some implementations, the battery device includes at least one cell assembly including a plurality of battery cells, a housing accommodating the at least one cell assembly therein and including a bottom plate and a sidewall, and a cooling plate configured to transfer heat generated by the cell assembly to outside the cell assembly and disposed between a lower surface of the cell assembly and the bottom plate, wherein the cooling plate includes a gas discharge hole through which gas generated by the cell assembly passes, a gas flow space disposed between the cooling plate and the bottom plate to allow gas discharged through the gas discharge hole to flow, and a blocking member disposed on the cooling plate to block flames or heat in the gas flow space from being transferred to the cell assembly.

A battery device comprising:

at least one cell assembly including a plurality of battery cells;
a housing structured to include a bottom plate and a sidewall for accommodating the at least one cell assembly in the housing and;
a cooling plate disposed between a lower surface of the cell assembly and the bottom plate of the housing and configured to transfer heat generated by the cell assembly to outside the cell assembly, wherein the cooling plate includes one gas discharge hole structured to allow gas generated by the cell assembly to pass through;
a gas flow space formed by the cooling plate, the bottom plate and the sidewall of the housing and located between the cooling plate and the bottom plate of the housing and configured to allow the gas discharged through the gas discharge hole to flow;
and
a blocking member disposed on the cooling plate and configured to block flames or heat in the gas flow space from being transferred to the cell assembly.
