Abstract

A system and method for the stabilization of battery temperature by alternating airflow through an internal ductwork of a cabinet housing electronic equipment and circuitry. Ambient air is drawn through one or more intake vents or louvers provided with the cabinet housing. Regulated airflow through the ductwork allows the cabinet housing's thermal management system to direct either cooler ambient air during warm periods or heated air during colder periods through the cabinet to stabilize the battery temperature as well electronics equipment and circuitry housed in the cabinet. At least a portion of the heated air is expelled through one or more exhaust vents. Because no active components are used for stabilizing battery temperature, thermal regulation is achieved even during utility power outages. Further, thermal energy is provided without the possibility of igniting hydrogen gas products generated by the battery units present in the cabinet.
