Abstract
Disclosed is a battery pack including a battery module having a plurality of battery cells, and a heat dissipation member provided in contact with a bus bar at a side surface of the battery module where electrode leads of the battery cells and the bus bar coupled to the electrode leads are disposed.
Claims20
A battery pack, comprising:
- a tray having a lower surface;
- a plurality of battery cells positioned in the tray and arranged in a linear array along a stacking axis extending parallel to the lower surface, the linear array having a width dimension and a height dimension orthogonal to one another and orthogonal to the stacking axis, the width dimension being parallel to the lower surface and the height dimension extending orthogonally to the lower surface, wherein a lateral surface of the linear array is defined by a side of the linear array extending in the height dimension and wrapping around a perimeter of the linear array in the height dimension;
- and
- a coolant channel extending along the lateral surface of the linear array, the coolant channel providing a flowpath configured to permit a cooling fluid to flow therethrough such that the cooling fluid encircles the linear array along the lateral surface.

A battery pack, comprising:
- a tray having a lower surface;
- a plurality of battery cells positioned in the tray and arranged in a plurality of groups arrayed along respective axes, the plurality of groups including a first group arranged in a first linear array along a first axis and a second group arranged in a second linear array along a second axis, the first and second axes being parallel to one another and extending parallel to the lower surface, wherein each of the plurality of groups has a width dimension and a height dimension orthogonal to one another and orthogonal to the respective axis, the width dimension being parallel to the lower surface and the height dimension extending orthogonally to the lower surface, wherein a lateral surface of each of the plurality of groups is defined by a side of the respective group extending in the height dimension and wrapping around a perimeter of the respective group in the height dimension;
- and
- a network of coolant channels defining respective flowpaths configured to permit a cooling fluid to flow therethrough so that the cooling fluid passes around the each of the plurality of groups, the network of coolant channels including a portion extending along the lateral surface of the first group and along the lateral surface of the second group, such that one of the flowpaths extends between the first and second groups.
