Shenzhen Communication Base Station Project

Shenzhen Lingshi Smart Energy Co., Ltd. is investing in a communication base station energy storage project, set to begin operation in Shenzhen in October 2024.
The project will have a total capacity of 3 MWh and uses a standardized solution with a single unit rated at 13 kW/40 kWh.

The system is composed of 40 kWh modules built with high-capacity 280 Ah lithium iron phosphate cells, designed to ensure both energy density and long-term reliability. Its air-cooled configuration, combined with IP54 protection, allows stable and safe operation across a wide temperature range from -30°C to 55°C and in 0–95% relative humidity (non-condensing).

With each battery pack and the overall system carefully arranged to optimize performance, this setup enhances backup power reliability and maximizes energy utilization for communication base stations under varying environmental conditions.

Communication base stations are the fundamental nodes of mobile networks. If power is lost and no backup is available, the base station stops operating, causing mobile signal outages and network disruptions.

Traditionally, diesel generators have been used as backup power, but they are noisy, slow to start, require frequent refueling and maintenance, and have environmental drawbacks.

Lithium iron phosphate (LFP) energy storage systems respond instantly, operate silently, and offer high automation. Their reliability far exceeds that of diesel generators.

During planned outages, such as grid maintenance, or unexpected outages caused by natural disasters or line faults, when the grid stops supplying power, the storage system seamlessly switches to backup mode and immediately powers the base station.

In addition, commercial electricity is often priced in peak, flat, and off-peak periods, with significant differences between them.

The energy storage system can charge from the grid during low-cost off-peak hours at night and discharge during high-cost peak hours to power the base station, thereby improving overall energy utilization efficiency.
