Remote Terminal Units (RTUs) are required for secondary substation
automation and telecontrol, powered by two integral valve regulated lead acid
batteries. The batteries have been subjected to high ambient temperature due to
the heat emitted from electronic components within the RTU and radiated heat
from the secondary power transformer, when located within the substation
building. Such temperature excursions can have a detrimental effect on battery
life. This project seeks to address this issue to ensure that battery longevity is
The project aims to develop a battery air conditioning solution to smooth out the
temperature variation and keep the battery ambient temperature within 20°C.
