1. A method of making an electric vehicle battery cold plate assembly, said method comprising:
providing a top plate having a lower major surface with at least one patterned open-faced cooling channel formed therein and intermediate land area;
providing a bottom plate having an upper major surface or a battery tray having an upper major surface;
masking so as to close the opening of the cooling channel;
applying a layer of organic bonding agent/adhesive, in liquid and/or tape form onto at least most or all of the lower major channeled surface of the top plate and optionally onto at least partially, mostly or all of the masking;
after a layer of the organic bonding agent/adhesive is applied, removing the masking to open the coolant channels; and
bonding the lower major surface of the top plate and the upper major surface of the bottom plate together using the applied organic bonding agent/adhesive,
wherein the intermediate land area of the top plate is bonded to the upper major surface of the bottom plate, and a surface of the enclosed cooling channel is formed by a corresponding portion of the upper major surface of the bottom plate or the battery tray.
