Dynamically Pressurized Pouch Battery System

A dynamically pressurized pouch battery system. One or more pouch batteries are placed in a fixed volume enclosure, which also contains coolant in direct contact with the pouch battery(s). A pump pumps the coolant into and out of the enclosure, thereby varying the pressure exerted by the coolant upon the exterior of the pouch batteries. The pump may cause the coolant to provide more or less pressure depending on battery cell conditions, such as voltage, state-of-charge, age, state-of-health, or temperature.
