Abstract
The present invention is directed to an environmental control system for use with a battery cabinet having at least one battery and a fan employable to circulate air through the battery cabinet, and method of operating the fan to circulate air through the battery cabinet. In one embodiment, the environmental control system includes a voltage sensor that monitors a voltage associated with the battery, and a battery temperature sensor that monitors a temperature of the battery. The environmental control system also includes a fan control subsystem, coupled to the voltage and battery temperature sensors, that activates the fan upon an occurrence of one of: the temperature of the battery exceeding a predetermined temperature, and the voltage associated with the battery exceeding a predetermined voltage.
