How many batteries does a communication base station use?
Each communication base station uses a set of 200Ah·48V batteries. The initial capacity residual coefficient of the standby battery is 0.7, and the discharge depth is 0.3. When the mains power input is interrupted, the backup battery is used to ensure the uninterrupted operation of communication devices.
Why do cellular base stations have backup batteries?
[...] Cellular base stations (BSs) are equipped with backup batteries to obtain the uninterruptible power supply (UPS) and maintain the power supply reliability. While maintaining the reliability, the backup batteries of 5G BSs have some spare capacity over time due to the traffic-sensitive characteristic of 5G BS electricity load.
When does a base station need a backup battery?
When the power supply of the grid is good or the base station load is in a state of low energy consumption, the backup battery of the base station is usually idle. Reasonable evaluation of the reserve energy required by the base station is the premise of its response to the grid dispatching.
How does the power load of a 5G base station affect communication load?
Therefore, the variation of the power load of the 5G base station is closely related to the communication load. It is divided into two kinds of structure, the one that doesn't change is the first structure, such as lighting and air conditioning load; due to the communication load. The second structure of the power load is proportional to the flow.
