“…The internal resistance (R 0 ) of the EEC battery model is the only parameter that can be estimated without disconnecting the battery; instead, only the float voltage mode is needed. In addition to this, this resistance is strongly related to the electrolyte level since the water loss increases the electrolyte concentration, which in turn increases the internal resistance value [4][5][6][9][10][11][12][13][28][29][30]. Consequently, R 0 is the selected indicator in this contribution to detect the low electrolyte level.…”

“…In this regard, the loss of electrolytes below the minimum level leads to a gradual reduction of performance and, consequently, the battery's end of life (EOL) [4][5][6][7][8][9]. Other aging mechanisms are: irreversible formation of lead sulfate, electrolyte stratification, positive plate corrosion, shedding, sludging, and internal short-circuits, among others [10][11][12][13]. These phenomena contribute to decrease the available capacity and to modify the battery's internal resistance (also known as ohmic resistance).…”

It is well known that a low level of electrolytes in batteries produces a malfunction or even failure and irreversible damage. There are several kinds of sensors to detect the electrolyte level. Some of them are non-invasive, such as optical sensors of level, while some others are invasive; but both require one sensor per battery. This paper proposes a different approach to detect the low electrolyte level, which neither requires invasive sensors nor one sensor for each battery. The approach is based on the estimation of the internal resistance of an equivalent electrical circuit (EEC) model of the battery. To establish the detection criterion of the low level of electrolytes, a statistical analysis is proposed. To demonstrate the feasibility of this approach to be considered a valid method, multiple experiments were performed. The experiments consisted of determining how the internal resistance is affected at eight different levels of electrolyte at different aging levels of vented lead–acid (VLA) batteries. The results have demonstrated the feasibility of this approach. Hence, this approach has the potential to be used for the reducing of sensors and avoiding invasive methods to determine the low level of electrolytes.

Battery Storage Technologies for Electrical Applications: Impact in Stand-Alone Photovoltaic Systems

Batteries are promising storage technologies for stationary applications because of their maturity, and the ease with which they are designed and installed compared to other technologies. However, they pose threats to the environment and human health. Several studies have discussed the various battery technologies and applications, but evaluating the environmental impact of batteries in electrical systems remains a gap that requires concerted research efforts. This study first presents an overview of batteries and compares their technical properties such as the cycle life, power and energy densities, efficiencies and the costs. It proposes an optimal battery technology sizing and selection strategy, and then assesses the environmental impact of batteries in a typical renewable energy application by using a stand-alone photovoltaic (PV) system as a case study. The greenhouse gas (GHG) impact of the batteries is evaluated based on the life cycle emission rate parameter. Results reveal that the battery has a significant impact in the energy system, with a GHG impact of about 36-68% in a 1.5 kW PV system for different locations. The paper discusses new batteries, strategies to minimize battery impact and provides insights into the selection of batteries with improved cycling capacity, higher lifespan and lower cost that can achieve lower environmental impacts for future applications.
