Abstract
A battery pack having a battery module and a cooling plate are provided. The battery pack has a bottom surface and a first plane that extends through the battery module parallel to the bottom surface. The cooling plate has a bottom pan and a top plate that are coupled together and extend along a longitudinal axis. The bottom surface of the battery module is disposed on the top plate. The bottom pan has a first cooling region with first and second flow path patterns therein that receive a refrigerant therethrough. The first and second flow path pattern are shaped and sized to maintain a temperature of first and second halves, respectively, of a cross-sectional area of the battery module within one degree Celsius of a first temperature level.
Claims13
A battery pack, comprising:
- a battery module having a bottom surface;
- a cooling plate having a bottom pan and a top plate that directly contact one another and are coupled together and define an interior region therebetween and extend along a longitudinal axis, the bottom surface being disposed on the top plate;
- and
- the bottom pan having a first cooling region with first and second flow path patterns therein that receive a refrigerant therethrough, the first flow path pattern being shaped and sized to maintain a temperature of at least a first half of a cross-sectional area of the battery module within one degree Celsius of a first temperature level, the second flow path pattern being shaped and sized to maintain a temperature of at least a second half of the cross-sectional area of the battery module within one degree Celsius of the first temperature level.
A battery pack, comprising:
- a battery module having a bottom surface and a first plane that extends through the battery module parallel to the bottom surface;
- a cooling plate having a bottom pan and a top plate that directly contact one another and are coupled together and define an interior region therebetween and extend along a longitudinal axis, the bottom surface being disposed on the top plate;
- and
- the bottom pan having a first cooling region with first and second flow path patterns therein that receive a refrigerant therethrough, the bottom pan having first and second triangular-shaped raised portions that are coupled to and contact the top plate, the first and second triangular-shaped raised portions having a first flow channel therebetween within the interior region, the first flow channel defining a portion of the first flow path pattern, the first flow path pattern being shaped and sized to maintain a temperature of at least a first half of a cross-sectional area of the battery module within one degree Celsius of a first temperature level, the second flow path pattern being shaped and sized to maintain a temperature of at least a second half of the cross-sectional area of the battery module within one degree Celsius of the first temperature level, the first half of the cross-sectional area of the battery module and the second half of the cross-sectional area of the battery module being coincident and parallel with the first plane.
