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 of base stations is usually set as 1.8 v, and we set the end voltage vE as 1.85 v to avoid extreme deep level discharge.
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.
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.
Among various battery technologies, Lithium Iron Phosphate (LiFePO4) batteries stand out as the ideal choice for telecom base station backup power due to their high safety, long lifespan, and excellent thermal stability.
The original battery allocation result is largely skewed that over 65 percent base stations are equipped with only one battery group. Our framework considers both the base station situations and battery fea-tures, allocating 2 battery groups to most base stations and 3 or 4 battery groups to those with long-time power outages.
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.
