Embodiment Construction

[0018] One or more specific embodiments are described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be understood that in the development of any such actual implementation, as in any engineering or design project, many implementation-specific decisions must be made to achieve the developer's specific goals, such as compliance with system-related and business-related constraints , these constraints may vary according to the implementation. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0019] The battery systems described herein can be used to power various types of electric vehicles (xEVs) and other high voltage energy storage / consumption applicatio...

Abstract

The present disclosure includes a battery system with a battery module (20) having electrochemical cells (32) inside a housing (30) which includes a first side (42) and a second side (44) opposite to the first side. The battery module includes a heat sink (49) coupled with the second side (44) of the housing and a thermal interface (50) disposed between, and in contact with, the heat sink (49) and the electrochemical cells (32). The thermal interface (50) contacts the base ends (53) of the electrochemical cells (32). The system further includes a cage (80) disposed about the battery module (20) wherein the cage includes a cage side (85) positioned next to the second side (44) of the housing and having openings (82) which enable air to be drawn into the cage and to pass over the heat sink (49).

Description

Background technique [0001] The present disclosure generally relates to the field of batteries and battery modules. More specifically, the present disclosure relates to passive thermal management features of lithium-ion (Li-ion) battery modules. [0002] This section intends to introduce to readers various aspects of technologies that may be involved in various aspects of the present disclosure described below. This discussion is considered helpful in providing the reader with background information to facilitate a better understanding of various aspects of the disclosure. Accordingly, it should be understood that these statements are read in this light and do not constitute admissions of prior art. [0003] Vehicles that use one or more battery systems for providing all or a portion of the vehicle's motive power may be referred to as xEVs, where the term "xEV" is defined herein to include all vehicles in which the vehicle uses electrical power for its vehicle motive power ...
