Embodiment 1

[0051] See Figure 4-6 , the main control cabinet AC220V or AC380V incoming line is connected to the relay, and the incoming line supplies power to 12 battery compartments. Each battery compartment has a charger and a battery. Each charger is connected to the battery one by one to form a battery charging circuit. , lead out the connecting terminals on the two poles of the battery, the positive and negative poles of each battery correspond to the corresponding connecting terminals, and the connecting terminals can be connected with the spare cabinet.

[0052] Correspondingly, the standby cabinet is also equipped with corresponding terminals on the main cabinet to ensure reliable connection between the battery on the main control cabinet and the unidirectional DC-DC power supply in the backup cabinet. A diode is added to the positive terminal of each power input of the standby cabinet to prevent the reverse connection of the input from burning out the power supply and affecting ...

Embodiment 2

[0055] See Figure 4 , 5 , 7. The difference from Embodiment 1 is that the DC / DC power supply of the backup cabinet no longer adopts a one-to-one correspondence with batteries, but uses a power supply method in which two batteries correspond to one power supply. After calculation, the power supply power of the 5G base station, Using 6 DC / DC power supplies can meet the requirements, so in the 12-storey main control cabinet, two batteries are used to supply power to one power supply. Using three batteries to supply power to one power supply, and so on, this embodiment saves a lot of cost on the premise of ensuring functions. When the power is off, take one of the backup cabinet power supplies as an example: the backup cabinet power supply starts to work, and a battery in the main control cabinet supplies power to the backup cabinet power supply. A battery provides power.

[0056] When the power supply of the base station is powered off (the main control cabinet and the base s...

Abstract

The invention relates to a standby power supply system for an intelligent battery-replacing and 5G base station. The system comprises a main control cabinet and a standby cabinet, the main control cabinet supplies power to a base station, and the standby cabinet is started to supply power to the base station after power failure, the main control cabinet comprises a power failure detection unit andbattery compartments, an inlet wire connected with the power failure detection unit supplies power to the plurality of battery compartments, a one-way DC / DC charger and a battery are arranged in eachbattery compartment, each charger is connected with a battery in a one-to-one correspondence manner, and power supply interfaces I are led out from two poles of the battery; the standby cabinet comprises a 48V output power supply and a 48V bus, each group of 48V output power supply connected with the 48V bus is composed of a plurality of 48V output power supplies connected in parallel, and a power supply interface II is led out from an output loop of each 48V output power supply and connected with the main control cabinet through the first power supply interface I. The system has the advantages that a direct-current power supply in the intelligent battery-replacing cabinet is used for timely and conveniently supplying power to the power-down 5G base station, the structure is simplified, the control is convenient, the reliability is high, and the cost is low.

Description

technical field [0001] The invention relates to the field of DC power supplies, in particular to an intelligent power exchange-cum-5G base station backup power supply system. Background technique [0002] Smart battery swap cabinets for takeaway guys and courier delivery personnel, also known as shared power swap cabinets, shared battery cabinets, swap stations, battery swap stations, as the name suggests, are used for battery replacement. In the past, when people's electric vehicles ran out of power, the first way people thought of was to find a place with a power outlet to connect the electric vehicles to the power supply to charge them. This traditional charging method is not only inconvenient, but also easily affects the work efficiency of takeaway boys and courier delivery personnel. With the power exchange cabinet, when using the power exchange cabinet, users only need to scan or scan their faces with their mobile phones to exchange fully charged batteries with dead b...
