Embodiment Construction

[0030] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. In the drawings, the relative sizes of regions or features may be exaggerated for clarity. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments described herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey to those skilled in the art express the scope of the invention.

[0031] It will be understood that when an element is referred to as being "coupled" or "connected" to another element, it can be directly coupled or connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly coupled" or "directly connected" to another element, there are no intervening elements present. Like numbers refer...

Abstract

A temperature controlled battery pack assembly (100) includes a housing (120) containing at least one battery cell, defining a battery chamber (104A) and including thermal insulation (124) surrounding at least a portion of the battery chamber. The thermal insulation inhibits thermal transfer between the at least one battery cell and the surrounding environment. A thermal bridge conductor (130) is disposed in the battery chamber and engages the at least one battery cell. The battery pack assembly further includes a thermoelectric cooler device (160) having an inner surface (162A) and an outer surface (164A), operable to actively transfer heat between the inner and outer surfaces using the Peltier effect. A heat sink device (170) is in contact with or connected to the outer surface. The battery pack assembly includes a fan (178) operable to force a flow of a heat transfer fluid across the heat sink device and into the environment. The thermal bridge conductor is in contact with or connected to the inner surface.

Description

technical field [0001] The present invention relates to batteries and more particularly to temperature controlled battery pack assemblies. Background technique [0002] High temperature exposure can significantly reduce the useful life of batteries, such as those used to provide emergency backup or auxiliary power for electronic equipment that performs critical functions such as computer systems, telecommunications systems, and medical equipment. Information technology (IT) equipment is typically placed in a controlled data center environment. While the environment of a data center has traditionally been a relatively cool environment by design, there is a trend towards higher data center temperatures in an effort to reduce cooling requirements and increase operational efficiency. This trend is enabled by IT equipment that is more tolerant of higher temperatures. Also, there is a shorter standby time transition when a data center is migrated to a cloud computing environment...
