Abstract: With the rapid development of the information and communication industry and “new infrastructure”, the infrastructure construction of China􀆳s 5G network is developing rapidly. While 5G networks have the characteristics of high speed, large capacity, low latency, and high reliability, the single-site power consumption of 5G base stations has also increased several times. It is particularly important to realize energy-saving operation of 5G base stations. This article discusses the energy-saving technology of 5G base station power supply system and cooling system to help 5G base station safe, reliable, green and low-carbon operation.

Key words: 5G base station, power supply, refrigeration, energy saving
