“…Batteries are more temperature sensitive than other forms of energy storage, but they are improving. Some datasheets and authors report operating batteries successfully as low as -30°C and as high as 75°C [1,8,22], however, the capacity, ESR, and cycle lifetimes of a battery will still degrade at extreme temperatures [43,46], and further study of these results is warranted. We note that supercapacitors also experience issues such as drastically increased ESR at very low temperatures [29].…”

For the past decade, the status-quo for energy harvesting sensors has been to buffer small amounts of energy in capacitors to intermittently work through a sensing task. While using capacitors for storage offers these systems indefinite lifetime, it comes at a cost -they must tolerate the decreased availability, lower energy utilization, and more complex programming models inherent to a volatile, intermittent design. We argue that many of these problems stem from insufficient energy storage and could be eliminated with the use of batteries. Recent advances in rechargeable battery technology weaken the historical arguments against their use. We believe that using batteries in energy harvesting sensors will push us closer to a class of reliable, general purpose devices that can better serve human-centric sensing applications than their capacitor-based counterparts at the cost of having a finite, but long, lifetime.

“…Self-discharge processes are complex including for example chemical and mechanical electrode corrosion, internal losses due to partial electron movements in the electrolyte etc. [14,16]. Instead of detailed mathematical description of self-discharge processes a more modest approach is suitable for our application.…”

Abstract-Energy storages are indispensable in regard to the development of the smart grid with increasing fluctuating power generation. A valid choice of energy storages is important to ensure the efficiency of the system and selected application. This study describes an initial approach to model energy storage systems as an equivalent circuit. This model is capable of analyzing different load scenarios and simulating the storage's behavior in dependence of three circuit components, i.e., resistance, inductance and capacitance. These model parameters define the storage system and can be used to test existing storage devices or find an optimal setting for selected load conditions. The model is tested in a load scenario with a residential building supported by photovoltaic generation.

“…Self-discharge Batteries are losing their charge capacity when they are stored for a certain period of time at certain temperature. During the stored period, batteries are losing a part of their charge due to the self-discharge (reversible capacity loss) [10]. The self-discharge characteristic varies from battery technology to battery technology and depends on the storage temperature and SOC at which the battery is idling.…”

“…However, the self-discharge rate is highly influenced by the storage temperature and SOC [10]; thus, the results presented in Figure 17 should be treated with caution if other storage conditions than the ones mentioned are targeted. …”

Uninterruptible power supply (UPS) systems have incorporated in their structure an electrochemical battery which allows for smooth power supply when a power failure occurs. In general, UPS systems are based on lead acid batteries; mainly a valve regulated lead acid (VRLA) battery. Recently, lithium ion batteries are getting more and more attention for their use in the back-up power systems and UPSs, because of their superior characteristics, which include increased safety and higher gravimetric and volumetric energy densities. This fact allows them to be smaller in size and weight less than VRLA batteries, which are currently used in UPS applications.The main purpose of this paper is to analyze how Li-ion batteries can become a useful alternative to present VRLA. In this study, three different electrochemical battery technologies were investigated; two of the most appealing Li-ion chemistries, lithium iron phosphate (LFP) and lithium titanate oxide (LTO) were compared with lead acid batteries, in terms of their basics characteristics (e.g. capacity, internal resistance) and their dependence on the operating conditions.
