Battery data analysis of communication base stations

How many base stations and backup battery features are there?

In this paper, we closely examine the base station features and backup battery features from a 1.5-year dataset of a major cellular service provider, including 4,206 base stations distributed across 8,400 square kilometers and more than 1.5 billion records on base stations and battery statuses.

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.

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.

How long does a battery last in a cellular communication base station?

for a new battery cell. According to the industry standard, the battery used in cellular communication base station is designed to provide power supply for about 10 to 12 hours and we thus set to 10. The second low voltage disconnect

Why do cellular base stations have backup batteries?

Abstract: 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).
