Abstract
A new device is provided for controlling and maintaining the ambient air temperature within a remote telecommunications battery enclosure. A thermoelectric device located in intimate contact with heat exchangers and fans configured such that at least one heat exchanger is positioned within or spaced in thermal communication with the interior of the battery enclosure, and at least one heat exchanger is positioned outside of or spaced in thermal communication with a thermal dissipation arrangement exterior to the battery enclosure. The system further has a sensor or microprocessor connected to the thermoelectric device and configured to control the system to heat or cool the battery enclosure by responsively reversing polarity of the thermoelectric device as indicated by ambient air temperature or battery temperature to maintain the air temperature within predetermined limitations. A hydrogen vent is provided to maintain sub lower explosive levels of hydrogen gas within the battery enclosure.
