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.
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.
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.
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.
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.
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.
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually. Emerging markets are adopting residential storage for backup power and energy cost reduction, with typical payback periods of 4-7 years. Modern home installations now feature integrated systems with 10-30kWh capacity at costs below $700/kWh for complete residential energy solutions.
Technological advancements are dramatically improving home solar storage and inverter performance while reducing costs. Next-generation battery management systems maintain optimal performance with 40% less energy loss, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $1,200/kW to $650/kW since 2022. Smart integration features now allow home systems to operate as virtual power plants, increasing homeowner savings by 35% through time-of-use optimization and grid services. Safety innovations including multi-stage protection and thermal management systems have reduced insurance premiums by 25% for solar storage installations.
