In recent years, with the rapid development of cloud computing, big data, edge computing, 5G and other information technologies, the amount of data has increased geometrically.

In the future, the data center will inevitably move toward the direction of modularization, and the data center battery can only adapt to the future modularization requirements of the data room if it is developed in the direction of high power, long life, narrow shape and modularity.

Through the scientific design and careful selection of materials, Narada has innovatively developed the HRL series of high-power batteries that are currently most suitable for data center use.

This battery uses an embedded grid alloy suitable for the data room. By reducing the maintenance difficulty of the battery, reducing the float current of the battery, and improving the float life of the battery, the battery energy consumption can be reduced and the operation and maintenance cost of the battery pack can be reduced. The purpose is to achieve both energy saving and carbon reduction.

The actual case proves that Narada’s HRL high-power battery has increased its power by 35%, the floor area is reduced by 30%, the battery load-bearing demand is reduced by 20%, the carbon emission is reduced by 37.5%, and the primary cost is reduced by 15%. It brings great economic benefits to users and are ideal for future modular UPS power battery configurations.

At the beginning of the cooperation, the two companies will be positioned in the solid-state lithium battery for energy storage applications. Prologium will provide production licenses to Narada, and will authorize solid-state battery cell production technology with an energy density of about 240Wh/kg to provide core equipment and materials for production. And assist in the planning and guidance of the plant.

Narada will become the exclusive authorized partner of Prologium in the energy storage market.

Based on Prologium ‘s high-automated production technology of solid-state batteries and market resources accumulated in the field of energy storage, Narada will gradually promote the industrialization of solid-state lithium batteries and plan to enter the electric vehicle market after commercialization of solid-state lithium batteries for energy storage.

2019 will be the first year of 5G commercial use. It is expected that the 5G network of China’s three major telecom operators will cover the whole country by 2021.The development speed of 5G is much higher than that of 4G and 3G. Therefore, Narada has adopted a more comprehensive layout strategy in this regard.

640.jpeg

Narada has been continuously tracking the new requirements of 5G technology for power systems, and has developed new products and solutions adapted to the 5G base station model in time to adapt to the new demands of network convenience and security in the 5G era.

 

Narada 5G communication power solution is a backup power system with high security and reliability specially developed for 5G communication base station. It is superior to traditional 4G solution in power density, specific energy and battery intelligent management, and adopting international advanced technology.The system uses lithium iron phosphate technology with higher safety and reliability, and the cycle life is more than 10 times that of traditional lead-acid batteries. The battery system is highly integrated, the mass energy density is more than 5 times that of the conventional battery, and the volumetric energy density is more than 3 times, which greatly reduces the space occupied and the load bearing demand.

 

Narada 5G communication power system also adopts advanced intelligent battery management system, which can remotely monitor the running status of equipment through the Internet, WIFI, Bluetooth, etc. It has the functions of timely monitoring, diagnosis, prevention and protection of the power system, greatly improving the security of power supply. In addition, Narada 5G communication power system adopts modular design. The system adopts different external interfaces for installation and expansion. It can be installed in standard rack installation and pole-mounted, which can be quickly deployed in 5G base stations, greatly accelerating the deployment speed of 5G base stations.

 

“This system adopts IP65 and above waterproof level and corrosion resistance, and has thermal management system such as heating and cooling. It can be installed in harsh outdoor environment and is used normally at -30 °C ~ 65 °C”. Narada related technical experts said.

 

At present, Narada has completed the development of 5G communication power system, and is currently cooperating with international telecom giants. With the expansion of 5G commercial, this system will be more widely used in the 5G telecom market at home and abroad.

 

At the same time, in the promotion of base station energy-saving systems, Narada will combine energy storage technology, energy-saving and emission reduction schemes, intelligent monitoring systems and the construction of traditional communication equipment rooms together to form a new application models and system solutions to promote the transformation of business models.

Innovative Products Solutions

Many countries such as India and Pakistan have an average temperature of 30-35°C during the hot season. Inside the telecom cabinet, the temperature is even higher and climb over 50 °C. You may already know it, for every 10°C increase in temperature, the battery life will be cut by two.

Due to the nature and construction of the lead acid battery, it cannot withstand that kind of environment, this is why telecom sites have to be equipped with air-conditioner.

Not only does it increase your capital expenses (CAPEX) and operational expenditure (OPEX) by spending thousands of dollars per year and per site in maintenance & electricity fees, it will also increase the energy used and thus increase your CO2 emissions. Reduction of Energy Consumption and increase of Energy Efficiency is one of the most important keys for Telecom Operators.

Home & Commercial Energy Storage

Solar energy systems are becoming a vital part of our overall energy picture. Roof-mounted solar panels create energy instantly from the sun’s rays. However, some of this energy is not immediately required and the excess can be saved to battery a storage. This surplus energy can be used at another time when the sun is not shining. The stored energy can also act as an emergency backup in the case of main’s failure.

When considering energy storage system solutions, the battery life and safety features are critical. This is why the NARADA solution comes complete with our well proven and advanced lead carbon and lithium-ion phosphate technology in a smart, robust cabinet, providing a safe and secure storage facility.

Battery Cabinet

The Narada Coolstar battery is designed to protect VRLA type lead acid batteries in telecommunication and photovoltaic energy storage applications against stressful ambient temperature conditions.

The Coolstar’s energy efficient operation allows to significantly reduce equipment-cooling costs by targeting the thermal management efforts directly toward the 48V batteries. It will minimize air conditioning energy costs of radio base stations by splitting the thermal management into natural ventilation and forced cooling. Coolstar is ideal for countries with hot or tropical climate and for any location where cooling/heating energy is at a premium and its consumption has to be minimized.

The Coolstar cabinet has been designed on the basis of extensive CFD simulations of cell layout and airflow pattern.

DG/Battery Hybrid

With the maturing of telecom industry, competitiveness and social responsibility are becoming more and more important and energy savings and CO2 emission reduction solutions become a hot topic. Meanwhile, the continuous increase in fuel costs for generators is driving operators who are using power in off-grid or unreliable-grid locations to search for more cost-effective ways to power their operations. Therefore, choosing a reliable and optimized power supply system is vital for staying competitive. Choosing an suboptimal hybrid technology may have a major impact on the site’s operating costs and increase the CO2 emissions unnecessarily.

In an optimally balanced hybrid power system many things should be considered. Below is an illustration of an integrated system consisting of Diesel Gen set, diesel fuel tank, energy storage battery, air conditioner, thermal management system and system controller
