Mobile base station battery base station power generation

How does a battery group work in a base station?

The equipment in base stations is usually supported by the utility grid, where the battery group is installed as the backup power. In case that the utility grid interrupts, the battery discharges to support the communication switching equipment during the period of the power outage.

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.

How many battery groups are in a mobile network base station?

Fig. 1a shows two lead-acid battery groups in a mobile network base station and each battery group contains 24 cell batteries (the rated voltage of each battery cell is 2v). The rated capacity of a battery group is usually 500 AH and it can support about 10-12 hours (i.e., the reserve time of a battery group is 10-12 hours).

Why do cellular communication base stations need a battery alloc?

Current cellular communication base stations are facing serious problems due to the mismatch between the power outage situations and the backup battery supporting abili-ties. In this paper, we proposed BatAlloc, a battery alloca-tion framework to address this issue.
