A rechargeable battery module comprising:
- a plurality of unit cells;
- and
- a unit cell housing and adapted to channel a coolant;
- wherein a supportive plate having protrusions adapted to contact the coolant is mounted on an internal surface of the housing.
The rechargeable battery module of claim.7, wherein a supportive plate with corrugated portions is located between the plurality of unit cells.
A rechargeable battery module comprising:
- a plurality of unit cells;
- and
- a unit cell housing adapted to house the plurality of unit cells and to channel a coolant;
- wherein a supportive plate with corrugated portions is mounted on an internal surface of the housing.
