Continuous power is essential for telecommunication companies. When a base station loses power, every device connected to that station can no longer be served. When a network node goes dark, customers in your home or business will experience outages for hours, even days. Telecommunication companies typically operate hundreds or thousands of network sites, many located in rural or harsh environments; therefore, the reliability of each network site’s energy source is their primary concern. LZY Energy has made its reputation engineering solutions with precision for the specific and demanding energy requirements of the telecommunication industry’s power infrastructure.
Why telecom sites place unique demands on energy systems
A telecom facility differs from both a residential property and commercial buildings in that it operates 24/7 without interruption. While the power requirements are typically steady, the equipment required to operate telecom networks is also extremely sensitive to fluctuations in voltage and other aspects of power quality; therefore, any potential damage can be quite extensive (e.g., a million dollars). Telcos often build sites away from populated areas, which also significantly limits their ability to access a reliable source of grid-based electricity; accordingly, maintenance visits may be comparatively infrequent and therefore expensive to coordinate.
The characteristics of a successful energy system for telecommunication facilities include: excellent reliability, reasonable thermal stability, robust remote monitoring capability, and a long design life as a result of reduced human intervention over time.
What a quality telecom energy cabinet actually delivers
LZY Energy’s telecom energy cabinet has been made so that those who are telecom infrastructure will be able to continuously and reliably draw on a dependable and high-demand energy source. The lithium iron phosphate battery system inside the telecom cabinet is what allows for these three things to happen. It has many features such as:
* High energy density
* Long cycle life
* Superior thermal stability
LZY Energy has created a battery system that has the capability to deliver 100% of the battery’s capacity over thousands of cycles and provides reliable performance even at high and low temperatures, which is unlike the lead-acid backup batteries that are currently common place in many telecom networks. In addition, with lithium iron phosphate batteries, there is minimal ongoing maintenance needed besides monitoring.
The telecom cabinet has battery storage, power electronics and communication interfaces all located inside one weatherproof enclosure that can be mounted outdoors. This design allows for quick installation, fewer components that can fail separately, and have a single integrated system to monitor instead of many different devices from many different manufacturers.
Remote monitoring that keeps operators in control
The remote monitoring technology incorporated into the LZY Energy telecom cabinet is also one of the most important features from an operational perspective. Each cabinet passes status information to the remote / central monitoring platform via the standard telecom management protocols system status, battery health, state-of-charge, temperature and fault alerts which allows operators to monitor the state of each and every site in the network from the central platform, without the need to send field engineers to do regular checks on the cabinets.
Solar integration for off-grid and hybrid telecom sites
An increasing percentage of telecom sites around the world are located in areas where there is no access to the grid or where there is very little reliability of the grid as a primary source of supply. Many of these sites are now using solar generation combined with battery storage as their standard site design in place of diesel generators, due to high-cost fuel, pollution and logistical difficulties for maintaining them over long distances in rural locations.
LZY Energy manufactures products specifically designed to seamlessly integrate with solar photovoltaic arrays, making them a natural fit for off-grid and hybrid telecom installations. The battery management system manages both forms of charging (solar & grid) intelligently by prioritising renewable forms of generation, only using backup supplies when absolutely required. This hybrid ability reduces reliance on both fuel and grid power while providing the necessary uptime for telecom operations.
Thermal management built for harsh environments
Telecom cabinet units are located on every part of earth in any type of climate. Tropical cabinets will be operated under consistently high temperature and humidity; as a result, if the telecom units’ equipment is in a northerly latitude, it will have to withstand very cold weather, lowering the performance of the batteries if they are not designed for cold weather operations. Similarly, cabinets located in deserts will experience significant variation in daily temperatures, putting mechanical and electrical stresses on the cabinets and their components.
To address these issues, LZY Energy designs an active and passive thermal management system into their cabinet, which regulates the temperature inside the cabinet to ensure that the battery halves are maintained at an optimum operational temperature, regardless of the conditions outside the cabinet, thus ensuring both highest performance and longest life.
Reducing total cost of ownership across the network
Upgrade of telecom energy systems is, by nature, an economic decision, and the total cost of ownership equation definitely tilts towards the use of new lithium-powered cabinets. The higher longevity of the lithium iron phosphate batteries translates to reduced number of replacement events during their lifetime. The removal of regular upkeep processes such as watering the flooded lead acid cells cuts down on personnel costs. Remote monitoring decreases the need for site visits. The incorporation of solar power negates fuel expenses.
A partner that understands the telecom industry
The selection process of an energy storage supplier to work with the telecom industry does not have much in common with buying any other kind of commoditized product. There is an understanding of the peculiarities of the field, high standards of performance, and severe penalties for failure, which may manifest themselves in the form of outages and costs of repairs. LZY Energy has an impressive level of experience with telecom energy requirements in every project and offers equipment designed for telecom use rather than modified from some general product.
It is these qualities that make LZY Energy a powerful ally when building a more advanced energy system for telecommunications.
FAQs
1. Why should you choose lithium iron phosphate batteries instead of the lead-acid version in telecom power supply applications?
LFP chemistry provides longer service life, doesn’t need any maintenance, works efficiently in wide temperature ranges, and demonstrates higher stability of capacities over time. Therefore, this chemistry perfectly meets needs for continuous operation at a base station.
2. Are LZY Energy cabinets compatible with current telecom infrastructure?
Yes. The cabinets are capable of working with established communication standards used by most modern telecom stations; therefore, their installation requires no complete reconstruction of a power system.
3. Can you install the battery cabinets outdoors even in severe climate conditions?
Yes. With active thermal management of battery cells, the enclosure provides optimal operating temperatures regardless of ambient air temperature outside, and its IP rating makes it suitable for harsh environmental conditions.
4. How do your batteries work in solar power plants located far from the grid?
Battery management system allows to use solar energy first, and switch to another source of electricity only if there is not enough renewable energy.
5. What occurs in case of a grid failure at a connected site?
The cabinet provides uninterrupted power generated from stored energy until the grid comes back up or until a recharge is needed using an alternate power source.
6. How long will an LZY Energy telecom cabinet operate before it needs replacing?
Using lithium iron phosphate batteries, the system is designed to perform for more than ten years with a slow, predictable drop-off in its capabilities that can be monitored and accounted for.
7. What kinds of maintenance activities are involved in the cabinet after it has been installed?
There is little need for maintenance. Monitoring is done remotely, while on-site inspections are not needed often. There is nothing to replenish or replace in the way of fluids, combustible parts, or other consumables.
