“…This is also consistent with the different voltage values at the peak of the distributions, battery "a" is higher than battery "b." Moreover, poor initial state of health has been repetitively mentioned as a reason for accelerated battery ageing [12]. This is also consistent with the different tilt of the observed RMSE evolution for both batteries (see figure 2b).…”

A battery ageing estimator based on the observed voltage distributions over a one month timescale has been defined and experimentally verified at different set-ups: the 450 PV-stand alone systems operating at the Pierre Auger Observatory and the 40 meteorological stations of Meteo Galicia. The systematic consideration of this indicator has allowed for the detection of prematurely ageing batteries, before they cause a lack of energy supply. This paves the way for a rather simple but still very effective surveillance of the state of health of stand-alone PV systems.

“…This approach reduces the converter stages and improves the system efficiency [5]. The variability of the power production of PV systems and stochastic nature of energy demand by loads forces to use indispensable energy storage devices with the optimal size [6] in DC microgrid to smooth the power flow and provide high-quality electric power. The use of battery bank energy storage (BBES) systems is a popular alternative to maximize penetration level of variable power coming from PV into DC microgrid.…”

This paper proposes a new demand-side management (DSM) scheme for the autonomous DC microgrid for the future building. The DC distribution system is considered as a prospective system due to the increase of DC loads and DC power sources such as photovoltaic (PV), and battery bank (BB). The BB responds to the changes in a power imbalance between PV generation and demand within an autonomous DC microgrid. The power loss during charging/discharging of the battery is the great challenge for the autonomous DC microgrid supplied by PV. It decreases the system efficiency. The control objective of the proposed DSM scheme is to use the PV energy more efficiently. The proposed control algorithm shifts the deferrable load from non-sunny hours to sunny hours and decreases the building demand during non-sunny hours. In this way it decreases the charging/discharging cycles of the batteries. This is reducing the power losses in the battery and improves system efficiency. The proposed scheme reduces the size of the PV plant, storage and capital cost of the system. The results showing a clear shifting of the load so that to get significant reduction in the system cost which is given numerically as percentatge saving.

“…Despite being a mature technology and relatively low priced (£150/kWh), lead acid batteries are sensitive to incorrect use. They are sensitive to temperatures above the design 25 • C; releasing more energy at high temperatures but also deteriorating more quickly, which reduces battery life by as much as 50% for each 8-10 K temperature increase [2,3]. Discharging beyond 25% depth of discharge for starting, lighting and ignition (SLI) batteries results in accelerated deterioration [4].…”

“…Discharging beyond 25% depth of discharge for starting, lighting and ignition (SLI) batteries results in accelerated deterioration [4]. Lead acid batteries need to be stored fully charged to avoid sulfation, and storage temperatures should not exceed 25 • C to slow down self-discharge [3]. When used with isolated PV systems, it is not always possible to charge the battery before storage as availability of electricity is dependent on local weather [2].…”

“…When used with isolated PV systems, it is not always possible to charge the battery before storage as availability of electricity is dependent on local weather [2]. Even when used as recommended, the longest lasting lead acid (valve regulated) batteries last a maximum of five years, well before other components of a power generation system need replacing [2][3][4][5]. Redox flow batteries are emerging as a viable option for stationary energy storage [6][7][8].…”

Developing Electrolyte for a Soluble Lead Redox Flow Battery by Reprocessing Spent Lead Acid Battery Electrodes

2017

Abstract:The archival value of this paper is the investigation of novel methods to recover lead (II) ions from spent lead acid battery electrodes to be used directly as electrolyte for a soluble lead flow battery. The methods involved heating electrodes of spent lead acid batteries in methanesulfonic acid and hydrogen peroxide to dissolve solid lead and lead dioxide out of the electrode material. The processes yielded lead methanesulfonate, which is an electrolyte for the soluble lead acid battery. The lead (II) ions in the electrolyte were identified using Inductively Coupled Plasma Mass Spectroscopy and their electrochemistry confirmed using cyclic voltammetry. The concentration of lead (II) ions was determined and it was found that using the higher concentration of hydrogen peroxide yielded the highest concentration of lead (II) ions. The method was therefore found to be sufficient to make electrolyte for a soluble lead cell.
