BATTERY PACK AND METHOD OF ASSEMBLING THE BATTERY PACK

摘要

A battery pack having a battery pack housing defining an interior region is provided. The housing further includes an inlet aperture and an outlet aperture communicating with the interior region. The battery pack further includes a battery module that is disposed in the interior region of the battery pack housing proximate to the inlet aperture. The battery module has a first battery cell, a heat exchanger, and first and second end plates. The first battery cell and the heat exchanger are disposed against one another, and are further disposed between the first and second end plates. The heat exchanger defines a first flow path portion therethrough. The first end plate has a first end portion that extends longitudinally past the first end of the first battery cell, and a second end portion that extends longitudinally past the second end of the first battery cell.

1. A battery pack, comprising:
a battery pack housing defining an interior region, the battery pack housing further having an inlet aperture and an outlet aperture communicating with the interior region; a battery module being disposed in the interior region of the battery pack housing proximate to the inlet aperture, the battery module having a first battery cell, a heat exchanger, and first and second end plates; the first battery cell and the heat exchanger being disposed against one another, and being further disposed between the first and second end plates; the heat exchanger defining a first flow path portion therethrough; the first battery cell having a first end and a second end; the first end plate extending substantially parallel to a longitudinal axis of the battery module, the first end plate having a first end portion and a second end portion, the first end portion of the first end plate extending longitudinally past the first end of the first battery cell toward the inlet aperture; the second end portion of the first end plate extending longitudinally past the second end of the first battery cell; the second end plate extending substantially parallel to the longitudinal axis of the battery module, the second end plate having a first end portion and a second end portion, the first end portion of the second end plate extending longitudinally past the first end of the first battery cell toward the inlet aperture; the second end portion of the second end plate extending longitudinally past the second end of the first battery cell; a thermally conductive housing being disposed in the interior region of the battery pack housing between the battery module and the outlet aperture of the battery pack housing; the thermally conductive housing defining a second flow path portion between the thermally conductive housing and the battery pack housing, the second flow path portion communicating with the first flow path portion; and an electric fan disposed in the interior region of the battery pack housing; the electric fan adapted to urge air to flow through the inlet aperture and through the first and second flow path portions and further through a portion of the electric fan and through the outlet aperture of the battery pack housing.
