Abstract
A battery module includes one or more cell assemblies with a plurality of unit cells, and a housing for mounting the cell assemblies therein and circulating a temperature control cooling medium through the cell assemblies. The cell assemblies are arranged in the longitudinal direction of the housing. A guidance unit is installed in a cooling medium passage formed in the longitudinal direction of the housing, and proceeds along the passage to guide cooling medium flow along the passage toward the cell assemblies.
Claims18
A battery module comprising:
- a plurality of cell assemblies spaced from each other, each of the cell assemblies having a plurality of unit cells being stacked in a first direction;
- a housing for mounting the cell assemblies within the housing, the housing having a cooling medium passage for a cooling medium and an inlet, wherein the inlet does not overlap with any of the unit cells in the first direction;
- and
- a guidance unit located between and spaced from each of the cell assemblies in the cooling medium passage to guide flow of a cooling medium along the cooling medium passage toward the cell assemblies, the guidance unit comprising:
- a guide plate extending in the first direction;
- and
- a plurality of protrusions that are spaced from each other and protrude from the guide plate toward the one or more cell assemblies.
4 more elements
A battery module comprising:
- one or more cell assemblies, each having a plurality of unit cells being stacked in a first direction;
- a cell barrier between adjacent unit cells of the one or more cell assemblies, the cell barrier comprising at least one channel;
- a housing for mounting the one or more cell assemblies within the housing, the housing having a cooling medium passage configured to allow a flow of a cooling medium in the first direction and an inlet, wherein the inlet does not overlap with any of the unit cells in the first direction;
- and
- a guidance unit installed in the cooling medium passage to change the flow of the cooling medium along the cooling medium passage from the first direction to a second direction toward the cell barrier, the guidance unit comprising a plurality of protrusions protruding from the cell assemblies toward the cooling medium passage to guide the cooling medium to the cell assemblies.
