Traction battery thermal plate with longitudinal channel configuration

摘要

A traction battery assembly for a vehicle is provided. The traction battery assembly may include a battery cell array and a thermal plate configured to support the battery cell array. The thermal plate may define an inlet port, two outer channels each having a channel inlet in communication with the inlet port, at least three inner channels disposed between the outer channels, and an outlet port. The ports and channels may be arranged such that fluid traveling through any two adjacent channels flows in opposite directions and fluid, when exiting the thermal plate, empties from one or more of the inner channels into the outlet port without first entering the channel inlets.
