INSULATING LIQUID IMMERSED BATTERY

摘要

A multi-cell battery pack may be designed to serve as a thermosiphon. Stated another way, multi-cell battery pack may be designed to incorporate a passive heat exchange technique based on natural convection, which circulates a substance (liquid, or gas such as air) without the necessity of a mechanical pump. In this way, insulating fluid in cavities between cells greatly enhances the likelihood of preventing a thermal runaway condition. The insulating fluid in cavities between cells may result in reduced arcing and the elimination of combustion within a battery housing.

主权项

1. A multi-cell battery pack comprising:
a pressure vessel housing a plurality of battery cells and having an internal volume; an insulating fluid configured to substantially fill a void between at least two battery cells in the plurality of battery cells; and a condenser disposed in the internal volume of the pressure vessel.
