Abstract

The present invention relates to the technical field of energy management, in particular to a fuel cell energy management system for base station backup power supply; including a main power circuit, control logic, control circuit, Hall sensor and relay; the energy management unit is switched by the control logic When the input current of the fuel cell, commercial power or lead-acid battery is selected, the input current of the fuel cell is first connected to the sampling board for sampling through the lead wire, and the collected power is compared with the set power, and then passed through the Hall sensor Measure the size of the input current, adjust the protection through the relay, and finally realize the closed-loop control through the power main circuit and the control circuit according to the established control strategy, and output the power required by the load; the invention designs reliable control logic to realize the mains, The automatic energy switching management between lead-acid batteries and fuel cells improves the reliability of the backup power supply; real-time reporting of alarm information and remote monitoring meet the requirements of unattended operation.

Description

technical field [0001] The invention relates to the technical field of energy management, in particular to a fuel cell energy management system for a base station backup power supply. Background technique [0002] In the field of base station communication power supply, the power supply system is required to be highly reliable, and its reliability is usually guaranteed by the backup power supply system. In order to ensure the uninterrupted power supply of communication bureau stations and base stations, lead-acid batteries and diesel generators are generally used as backup power. When the mains power of the base station is naturally interrupted, the backup power supply is activated to supply power for the communication equipment of the base station. Stationary or mobile diesel generators, whether they are diesel generators or gasoline generators, have disadvantages such as loud noise, serious exhaust pollution, and large consumption of primary energy. [0003] Because the h...
