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.
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.

FAQS about Relationship between soc and voltage of energy storage battery
What is state of charge (SOC) in lithium ion batteries?
The state of charge (SOC) is one of the most important states of LIBs that is monitored online. However, the model-based method state of charge estimation requires an accurate Open circuit voltage (OCV), which is an important characteristic parameter of lithium-ion batteries, that is used to estimate battery state of charge (SOC).
What is the relationship between OCV -SOC and lithium ion battery?
The OCV -SoC follows linear relation in Lead acid batteries while it's no linear in Lithium-Ion Batteries as shown in Fig. 1 and Fig. 2 respectively. The open circuit voltage needs the battery to be in unloaded condition as it takes time for voltage to reach its steady state.
Does battery voltage depend on SoC?
The battery voltage depends on the SOC, and the error of voltage-based SOC estimation will increase at the beginning and end of the SOC range . Since the SOC rate is between 20% and 80%, the voltage variations in this range are very limited (Fig. 3) so that the battery voltage can be considered constant.
How to estimate battery SoC?
Direct techniques, such as OCV method is used to validate the SoC estimation results. KF method can estimate battery SoC, even when the states are affected by external perturbations. This method can estimate battery SoC online in real time with high accuracy.
What is the relationship between voltage and SOC?
The relationship between voltage and SoC is not linear. This means that a slight change in voltage can represent a significant change in SoC at specific points of the discharge curve. For instance, a battery's voltage may remain relatively stable between 40% and 80% charged, but it can drop sharply as it approaches 20% or below.
Does SoC affect the internal resistance of a battery?
Additionally, SOC affect the internal resistance of the battery. When SOC decrease to 70 %, the effectiveness of estimating internal resistance gradually diminishes in this study because of the reduction in the size of the covariance matrix in the algorithm, and the estimated internal resistance values only fluctuated slightly.
