Battery pack

A battery pack comprising:

• a battery stack that is configured by stacking a plurality of battery cells and includes a cooling air passage between the battery cells adjacent to each other;
• a battery case that houses the battery stack;
• an intake chamber that is positioned below the battery stack in the battery case, is communicated with the cooling air passage, and receives supply of cooling air flowing from an intake port provided at one end in a stacking direction of the battery cells to another end of in stacking direction;
• an exhaust chamber that is positioned above the battery stack in the battery case, and is communicated with the cooling air passage;
• and
• a plurality of flow regulation plates provided in the intake chamber, wherein
• the flow regulation plates are positioned on a downstream side to which the cooling air flows, each of the flow regulation plates extends along the stacking direction, and the flow regulation plates are disposed at intervals in a direction orthogonal to the stacking direction in a top view of the battery stack.
