Patent ID: 7764496

Claim:
In an energy storage cell pack including multiple rows of vertically oriented energy storage cells that radiate heat in a longitudinal axial direction upwards and downwards towards opposite respective upper and lower electrically conductive and heat conductive terminals, the energy storage cells further including an energy storage cell body, the energy storage cell pack including an enclosure with upper and lower ends that encloses the energy storage cell bodies of the energy storage cells while exposing the upper and lower terminals out of the respective upper and lower ends of the enclosure, an energy storage pack cooling system comprising: upper and lower respective terminal heat sinks thermally connected to the respective upper and lower terminals above and below the upper and lower ends of the enclosure; a blower and cooling assembly that circulates a heat transfer fluid past the upper and lower respective terminal heat sinks outside of the enclosure to cool the energy storage cells without circulating the heat transfer fluid past the energy storage cell bodies of the energy storage cells enclosed within the enclosure.
