ABSTRACT:
Disclosed herein is a battery insulator apparatus which in the preferred embodiment comprises an insulating enclosure within which the battery is placed. The enclosure includes a pair of vents operable to open or close passageways leading from outside the enclosure to the interior of the enclosure. A vent includes a diaphragm and a compression spring positioned to normally move the diaphragm against an opening leading to the interior of the enclosure. The space behind the diaphragm is connected to a vacuum source, and application of a vacuum to the space causes the diaphragm to collapse against the spring, and thereby to move away from the opening to the interior of the enclosure. Alternative to the vacuum-operated vents, a shutter vent is mounted over an opening of the enclosure and is operable by air movement, such as that generated by the fan of an automobile engine, to open and permit air flow. When the vacuum-operated vents are connected to the vacuum system of an automobile engine, the vents are open when the engine is running, and are closed when the engine is not operating.
