MARINE ENERGY STORAGE UNIT AND A METHOD TO PREVENT THERMAL RUNAWAY IN A MARINE ENERGY STORAGE UNIT

摘要

A marine energy storage unit having a thermal runaway safety barrier to prevent cell temperature rises. The marine energy storage unit comprises: a plurality of stacked battery cells (4); and at least one closed module cabinet (10) having an internal cooling system. The internal cooling system comprises a closed cabinet cooling circuit (3) having a water-air exchanger (20) for cooling air of the battery cell (4). The water-air exchanger (20) is connected to a water-water heat exchanger (30) receiving water from an external source.
