Abstract
A fluid cooled series/parallel battery pack is provided with a fluid flow system. A plurality of prismatic battery cells are arranged in parallel in two or more rows. Fluid flows in a series flow configuration from an upstream row of batteries to a downstream row of batteries. A bypass passageway provides additional fluid flow to an inner plenum located between the rows of batteries to reduce pressure drop and provide more uniform temperatures within the rows of battery cells.
