Telecom Battery Cooling

by Falk von Wildenradt24. März 2013

In more remote locations a reliable power supply is not always possible. Power can come from a variety of sources such as solar panels, wind turbines or even a diesel generator.

Avoid unnecessary battery drain

Telecom Battery backup is typically used when the main power supply fails, for example when there is no power grid or where the grid is unstable due to grid failure. In such cases batteries become the main power source until the normal electrical supply resumes. Although convenient, batteries are expensive to buy and replace.
They are also a challenge to handle, due to the fact that storing them at high temperatures significantly reduces their lifetime.
The optimal temperature for batteries is 25°C. Anything above this will shorten their life expectancy and provide their owners with an inconvenient replacement cost.

In some geographical regions, the batteries will experience tempe-ratures 20-30 degrees above zero, reducing their lifetime to a mere 25% compared to batteries that are kept within optimal temperatures.
In fact, for approximately every 10 degrees the temperature around the batteries increases, their lifetime can drop by as much as 50%.

Optimal Telecom battery cooling

A key issue for the base station’s overall performance is that the batteries are stored in an environment that will provide maximum cost efficiency and performance.
A few years ago battery packs were typically placed in the same areas as the electronics systems. Such base stations were kept at 25°C to ensure that the lifetime of the batteries was maintained.
This is somewhat lower than the required temperature for the electronics, which can comfortably handle temperatures of around 32°C. In recent years designers have therefore begun to move the battery packs outside, allowing the cooling system to ensure the optimal temperature for both electronics and batteries.
