“…Due to the nature of the charge-discharge characteristics of batteries there is a large variation of voltage at the battery terminals in a complete charge discharge period. [1][2][3][4][5][6][7] To protect DC loads from this unregulated voltage, many special designs are implemented such as diode droppers, DC-DC converters or float cum boost chargers. 8,9 Diode droppers provide a simple solution at the cost of reduced efficiency.…”

A wide variety of AC/DC power converter topologies have been developed in order to improve the system efficiency, input power factor and system redundancy for stationary battery energy storage systems. Due to the nature of high-power batteries, there is a big voltage difference between battery terminals from the end of discharge to the high charge value. To prevent unregulated battery voltages from harming the system loads, several techniques are used in the industry. A well-known old technique named as diode dropper is simple but suffers from low efficiency. Using a DC-DC converter is more advantageous, although it increases the cost. In this paper, the use of partial power processing converters which attract interest these days has been proposed as an alternative. The proposed full bridge/push-pull series connected partial power converter has a slight modification compared to the classical one presented in the literature. A system with 22 kW power rating was designed and tested. In order to compare the results, a two-switch buck-boost converter was also designed and tested for the same conditions. The results show that the proposed converter is superior to both the two-switch buck-boost converter and other topologies in terms of efficiency and response speed. Efficiencies of 97%–99% have been attained with the proposed converter.

“…The world's energy needs were mostly met with fossil fuels. During this period, very important researches has been done on renewable energy sources, which do not have a negative impact on natural life [2]. Energy generation systems using renewable energy sources are generally used in mountainous areas where electricity transmission is difficult and expensive, on islands with their own electricity network, to meet the electrical energy needs of settlements [3].…”

In this study, a test device is developed to measure the capacities and performances of high capacity battery banks and to detect broken cells. Batteries lose their performance over time due to their chemical properties, storage and usage conditions, production technologies. Some batteries may even become completely unusable long before the promised life cycle. Through this test device, the instant capacity of the battery banks is measured. Based on the data obtained, quantitative data such as state of health and nominal energy of the battery bank are calculating. It is determined whether the battery bank will meet the need according to its intended use. In this way, it is ensured to prevent possible losses by determining the battery cells or groups that need to be changed.

“…This capacity loss was investigated by Blank et al [6] setting depth of discharge (DOD) from 100 % to 130 %. It was stated that significant part of the initial capacity was lost because of overdischarge just after a few cycles.…”

In recent decades, more and more electronic systems (start-stop, drive-by-wire, brake-by-wire) have been developed in the automotive industry therefore reliable power sources are necessary. It is essential to understand thoroughly the detailed behavior of the battery to increase its efficiency, stability and monitorability which is the most popular field nowadays. Over-discharge plays an important role in aging because it increases the probability of initiation of grid corrosion, sulfation and loss of active mass. In this work, the effects of over-discharge of lead-acid battery have been investigated via internal resistance increase and temperature change separately for both the negative and the positive electrode. Most of the measurements were carried out in a prepared test cell (which contained a negative and a positive plate, an Ag│Ag2SO4 reference electrode, a shunt for measuring current accurately) connected to a dummy battery and an electronic load.
