An outdoor battery cabinet is formed to include a cooling system to extend the life of the housed batteries. The cooling system comprises a ventilation system including an air intake unit, an exhaust unit and a thermostat control. The interior surface of the cabinet is covered with a layer of insulative material. The ventilation system is configured to turn 'on' when the outdoor temperature drops below the interior cabinet temperature, thereby cooling the housed batteries. Once the outdoor temperature rises above the cabinet temperature, the ventilation system is turned 'off' and the insulation in the cabinet functions to maintain the cooler ambient temperature within the cabinet. To minimize the effects of wind forcing air through the ventilation openings, the intake and exhaust louvers are located on the same side of the cabinet.

An improved battery compartment design for use with an outdoor equipment enclosure includes a raised floor area such that a significant portion of the bottom surface area of the battery is exposed to air flow through the cabinet. The enclosure is configured such that the outdoor air used by an included heat exchanger first passes through the battery compartment. When the outdoor air is cooler than the area in the battery compartment, the heat exchanger is turned 'on' and this cooler area flows around all surfaces of the batteries, thereby reducing the battery temperature at a faster rate than conventional designs.

A cooling system for an outdoor equipment enclosure includes a nested columnar heat exchanger used in combination with a diverter for controlling the flow of outdoor air. The heat exchanger includes an interior column coupled to a upper exhaust fan for drawing outside air upward through the enclosure. An outer column, formed to surround the interior column, provides a path for interior air flow. The diverter is positioned between the main equipment compartment and an underlying battery compartment. During the period of time that the outdoor air is warmer than the air in the battery compartment, the diverter guides the outdoor air directly into the heat exchanger. When the outdoor temperature drops, the diverter closes off this path and instead forces the outdoor air through the battery compartment and then into the heat exchanger, thereby cooling off the batteries as well as lowering the temperature in the main equipment enclosure.
