Abstract

An energy storage system includes a container enclosing a battery cell array and having a fluid which surrounds the battery cell array. The system can include a refrigeration system to increase heat energy transfer from the battery cells. The system can include an external fluid loop configured to carry the fluid externally from the container through a heat exchanger. The system can also include a wall having a communication port which is configured to connect with an enclosure and convey electric signals through the wall.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application 61 / 781406, filed March 14, 2013, which is incorporated herein by reference in its entirety. Background technique [0003] Vehicles containing electric motors require high voltage energy storage systems in order to provide the motor with the proper amount of energy. High voltage often requires multiple battery cells to be electrically connected together in series. Because heat is a by-product of generating electricity, battery cells generate heat as they charge and discharge due to chemical reactions inside the cells. When multiple battery cells are placed in close proximity, the amount of heat generated by each cell can be multiplied throughout the system and can cause problems such as thermal runaway of the cells that can destroy the storage system. Furthermore, to optimize energy efficiency, a uniform temperature of the battery cells must be maintained. ...
