Lithium Battery Backup for Small Cell Sites

Emergency and backup power are integral to the reliable operation of mission-critical systems and facilities, including telecom infrastructure and mobile switching centers large and small. Diesel generators have traditionally been used to provide emergency backup. Clean decarbonization and electrification efforts are leading to Lithium Ion batteries becoming a viable alternative to diesel generators.

Many small cell sites and mobile switching centers were constructed over the past 20-30 years and are restricted to the space available for all their operational hardware, including telecom batteries. As energy demands increase, so do the energy backup requirements. 48V Lithium Ion batteries provide nearly double the energy density of lead acid batteries traditionally used in these mobile switching centers.

Lithium-Ion batteries are the critical pillar in a fossil fuel-free economy and their uses in electric vehicles and stationary energy storage have grown exponentially in recent years, due to technological advances and significant price declines. This is making Lithium-Ion batteries a cost-effective solution for energy storage and backup in mobile switching centers.

Diesel generators have traditionally been used to provide emergency backup. Clean decarbonization and electrification efforts are leading to Lithium Ion batteries becoming a viable alternative to diesel generators.

Small cell sites can require multiple hours of backup power. 48V Lithium-Ion batteries are more energy dense, meaning they can provide more runtime in a smaller space than their 48V battery alternatives. This allows operators to store more energy for use during power outages at remote mobile switching sites in the same footprint they currently have.

Unlike diesel generators, when batteries are not used for backup, they can double up as battery energy storage systems (BESS) that help address the imbalances of the grid, coming from excess or deficits between the production of electricity and consumption in real time. This can change telecom batteries from a liability to an asset for mobile switching center and small cell sites operators.

Green Cubes offers multiple lithium ion batteries for telecom applications to meet the exacting requirements of emergency power backup. Green Cubes Battery Backup Units (BBUs) can also be a building blocks of a BESS. Green Cubes Lithium-Ion Systems provide the following benefits over Diesel Generators:

• Carbon Footprint
  Lithium-Ion Batteries offer a clean environment friendly option over Diesel Generators and their harmful CO2 emissions.
• High efficiency
  Lithium-Ion batteries have a higher energy efficiency compared to Diesel Generators.
• Less maintenance
  Lithium-Ion batteries do not require maintenance like Diesel Generators.
• Higher energy density
  Lithium-Ion Batteries offer the highest energy density enabling them to consume same or lesser space compared to Diesel Generators.
• Lower Operating Costs
  Lithium-Ion based storage provide a lower operating cost compared to increasing Diesel prices.
• Parallel Revenue Stream
  Lithium-Ion Batteries can provide a parallel revenue stream through BESS enabled services.
