4 FAQs about Base station emergency battery

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 many battery groups does a base station have?

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.

How long do base station batteries last?

After using BatAlloc to allocate suitable numbers of battery groups for base stations, the average battery lifetime has achieved to 4.3 years, roughly 1.8 times longer than that of the original allocation. The results indicate that our framework can also better protect base station batteries and significantly pro-long their average lifetimes.

What happens if a base station has multiple battery groups?

When a base station is equipped with multiple battery groups, the impact of activi-ties is actually shared by all these batteries. Then the impact on every single battery should be proportionally reduced. In practice, there may be other requirements that limit the number of battery groups being installed at a base sta-tion.
