Battery Racks & Accessories

Narada offers a complete line of standard and seismic racks designed and built exclusively for Narada standby power batteries.

Narada battery racks mainly can be divided into three groups:

1. Standard racks for both 48V and high voltage system with cell restraint equipment and electricity insulation.

2. Seismic racks for both 48V and high voltage system are designed to meet Zone 4 requirement, e.g. the Uniform Building Code (UBC), or Bellcore Network Equipment-Building System (NEBS) requirement, Telecordia standard.

3. Vertical battery racks are designed for both tubular flooded and gel batteries. The racks comply with IEEE693, NEBS, Telecordia, UBC standards for substations, Telecom, Switchgear and UPS applications.

Main concerns and advantages of Narada battery racks:

Cell restraint equipment is offered for standard racks to provide shock protection.

All shock protected and seismic racks are supplied with anti-static spacers and cell clamps to minimize cell damage caused by an earthquake.

For additional protection, all racks can be installed with a rubber coating for electricity insulation in the event of a spill and short circuit.

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.

Keeping the battery temperature below 25°C is important to the battery life.

Uniformity of the batteries’ temperature is a priority.

Cooling must be adjusted based on different scenarios.

Hydrogen management is a key concern for safe operation.

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
