Get a quoteThe base station power cabinet is a key equipment ensuring continuous power supply to base station devices, with LLVD (Load Low Voltage Disconnect) and BLVD (Battery Low Voltage Disconnect) being two important protection mechanisms in the power cabinet.
Assume the rated voltage of a communication base station’s battery is 48V, with the BLVD threshold set to 42V. When the mains power fails and the battery starts supplying power, the power system continuously monitors the battery voltage through the voltage detection circuit.
Backup power systems in telecom base stations often operate for extended periods, making thermal management critical. Key suggestions include: Cooling System: Install fans or heat sinks inside the battery pack to ensure efficient heat dissipation.
Compatibility and Installation Voltage Compatibility: 48V is the standard voltage for telecom base stations, so the battery pack’s output voltage must align with base station equipment requirements. Modular Design: A modular structure simplifies installation, maintenance, and scalability.
Among various battery technologies, Lithium Iron Phosphate (LiFePO4) batteries stand out as the ideal choice for telecom base station backup power due to their high safety, long lifespan, and excellent thermal stability.
Overall, the power supply and backup battery system provide both AC line power and DC battery backup power to ensure the base station remains powered when AC line power is disabled. Figure 4 shows the circuit blocks of the power supply and backup battery system. Figure 4. Power supply and backup battery system block diagram.
