Abstract
A battery module is disclosed. The battery module according to the present disclosure includes a battery cell assembly including a plurality of battery cells stacked in a front-rear direction, a case configured to accommodate the battery cell assembly, and a cooling unit accommodated in the case and including a cooling bus. The cooling bus includes a cooling bus body that is accommodated in the case and extends in a direction in which the plurality of battery cells are stacked.
Claims20
A battery module comprising:
- a battery cell assembly including a plurality of battery cells stacked in a front-rear direction;
- a case configured to accommodate the battery cell assembly;
- and
- a cooling unit accommodated in the case, the cooling unit including a cooling bus,
- wherein the cooling bus includes a cooling bus body that is accommodated in the case and extends in a direction in which the plurality of battery cells are stacked.
A battery pack comprising:
- at least one battery module;
- a battery management module connected to the at least one battery module;
- and
- a cooling module including a cooling tank containing a coolant,
- wherein the at least one battery module includes:
- a battery cell assembly including a plurality of battery cells stacked in a front-rear direction;
- a case configured to accommodate the battery cell assembly;
- and
- a cooling unit accommodated in the case, the cooling unit including a cooling bus,
