What is a battery energy storage system?

A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.

What is a cellular base station battery?

Batteries used in cellular base stations are typically located in cabinets that are vented to protect the vital equipment from the fumes and corrosive chemicals found in the wet cell batteries, which are often lead– acid or valve regulated lead-acid (VRLA).

Why do cold batteries need a higher charge voltage?

Specifically, cold batteries require a higher charge voltage in order to push current into the battery plates and electrolyte, and warmer batteries require a lower charge voltage to eliminate potential damage to VRLA cells and reduce unnecessary gassing if flooded cells are used.

How long does a battery last in a cellular base station?

The heat generated within the battery cabinet can vary depending on the ambient temperature. For reliable operation and maximum useful battery life, the enclosure must be maintained between +10°C to +30°C. Batteries used in cellular base stations are usually placed in cabinets to protect the equipment. No battery lasts forever.
