Abstract
In an energy storage cell pack including at least one energy storage cell that radiates heat in a longitudinal axial direction outwards, towards opposite electrically conductive and heat conductive terminals, a terminal heat sink includes a receiving section for structurally receiving a terminal of the opposite electrically conductive and heat conductive terminals, and more than one heat conductive cooling fin radiating outwardly from the receiving section, wherein the more than one cooling fin radiates outwardly from the terminal when the receiving section structurally receives the terminal for dissipating heat from the terminal to cool the at least one energy storage cell.
