1. A battery pack comprising
a battery pack housing, the battery pack housing comprising a container, and lid that closes an open end of the container and is joined to the open end of the contained via a fluid-impermeable seal, the battery pack housing being filled with a first fluid that is dielectric; and
a battery module disposed in the battery pack housing, the battery module including
a module housing that is fluid permeable and includes a fluid passageway,
a plurality of electrochemical cells disposed in the module housing in such a way that terminals of the cells are exposed to fluid disposed in the fluid passageway, and
a thermal management system that includes
an inlet plenum assembly disposed at a first end of the battery module, the inlet plenum assembly comprising an inlet plenum, and an inlet flow diverter that is disposed between the inlet plenum and the module housing:
an outlet plenum assembly disposed at a second end of the battery module, where the second end is opposite the first end, the outlet plenum assembly including an outlet plenum; and
a fluid pump that directs fluid to the inlet plenum assembly via a fluid delivery line and receives fluid from the outlet plenum assembly via a fluid return line.
