Advances in battery technology can help solve energy crisis Despite financial barriers, telecom carriers can still have better control of their diesel consumption by implementing alternatives such as using deep charge batteries as the main power source. Deep charge batteries store electricity in a chemical form, inside a closed-energy system. They can be re-charged and re-used as a power source in remote locations.
Possessing a unique combination of expertise in renewable energy and IT and communications infrastructure solutions, Emerson Network Power provides products and services that reduce diesel consumption for off-grid base stations by supplementing diesel generators with deep charge batteries.
Cope with the next billion subscribers with Emerson’s Charge-Discharge Solution (CDC) The CDC Solution is suited to remote areas where grid power is either inaccessible or unreliable. It helps telcos’ achieve their green and OPEX-saving initiatives by reducing diesel dependence and carbon emission.
The hybrid solution utilizes deep charge batteries to provide power. Instead of having 2 generators providing continuous power, only one generator charges the battery. The fully-charged battery then provides power efficiently to the load.

The CDC system optimizes existing infrastructure such as fuel tank, generators, power system and others. |
How it works The solution works in two ways:
 |
|
One: When the mains fail, the deep charge batteries will automatically support the load. When the batteries discharge to a settable depth, the diesel generator will start supporting the load and charge the batteries. When the mains return, the system will turn off the diesel generators and the mains will support the load and charge the batteries. |

|
Two: The batteries support the load. When the batteries discharge to a settable depth, one diesel generator will work to support the load and charge the batteries. Once the diesel generator works more than the settable alternation time, the system will switch off the generator and switch on another generator. Once the batteries are fully charged, the system will switch off the generator and allow the batteries to fully support the load. | The CDC solution is an intelligent suite of economic and reliable components -- it comprises a generator, the battery solution, power system, power controller, smart outdoor enclosure as well as Emerson’s environmental monitoring system that enables operators to efficiently maintain on-site power.
