Battery temperature stabilization system and method

A method of passively stabilizing temperature within an enclosure including an electronic equipment compartment and a backup battery compartment, comprising the steps of:

• receiving a select amount of ambient air into said enclosure through an intake vent;
• determining said battery compartment's temperature;
• if said battery compartment's temperature is greater than a select temperature, circulating said ambient air in proximate contact with said battery compartment prior to directing said ambient air via a ductwork chamber to a heat exchanger operating to transfer heat generated in said electronic equipment compartment, thereby regulating said battery compartment's temperature in warmer ambient conditions;
• and
• otherwise, directing said ambient air via said ductwork chamber to said heat exchanger for warming said ambient air, said warmed ambient air thereafter circulating in proximate contact with said battery compartment in order to maintain said battery compartment's temperature in cooler ambient conditions.

A battery temperature stabilization system, comprising:

• a housing including at least one intake vent and at least one exhaust vent;
• a plurality of air passage ways for circulating air to an electronic equipment compartment and a battery compartment disposed in said housing, said battery compartment including at least one battery operable to provide backup power to circuitry disposed in said electronic equipment compartment;
• at least one heat exchanger unit operable for transferring heat from said electronic equipment compartment into a ductwork chamber forming a portion of said air passage ways;
• and
• means for controlling air flow through said air passage ways and said intake and exhaust vents, said means operating to route air through said ductwork chamber in one of two directions, wherein ambient air drawn in is first heated by said heat exchanger before being directed to said battery compartment when said battery compartment's temperature is lower than ambient temperature, otherwise said ambient air is directed to flow in proximate contact with said battery compartment prior to receiving heat from said heat exchanger.
