Abstract
A vehicle traction battery assembly may include a traction battery cell, a case, and a thermal plate. The case may define a cavity to receive the traction battery cell and has a first side defining a first form feature. The thermal plate may be for positioning adjacent the traction battery cell and define a coolant channel sized for engagement with the case via the first form feature such that traction battery cell is in thermal communication with coolant flowing through the coolant channel. The first form feature may be serpentine-shaped or S-shaped. The first form feature may be castle-shaped from a cross-sectional plan view. The case may be multi-layered and include a first polymer layer, a second polymer layer, and an aluminum layer disposed between the polymer layers.
