Lithium batteries have become the most commonly used battery type in modern energy storage cabinets due to their high energy density, long life, low self-discharge rate and fast charge and discharge speed.
The 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.
Energy Storage Cabinet is a vital part of modern energy management system, especially when storing and dispatching energy between renewable energy (such as solar energy and wind energy) and power grid.
STS can complete power switching within milliseconds to ensure the continuity and reliability of power supply. In the design of energy storage cabinets, STS is usually used in the following scenarios: Power switching: When the power grid loses power or fails, quickly switch to the energy storage system to provide power.
The following are several key design points: Modular design: The design of the energy storage cabinet should adopt a modular structure to facilitate expansion, maintenance and replacement. Battery modules, inverters, protection devices, etc. can be designed and replaced independently.
Assume the output voltage of a communication base station’s power system is 48V, with the LLVD threshold set to 40V. When the mains power fails and the battery starts supplying power, the power system continuously monitors the output voltage through the voltage detection circuit.
