    Opis:
    The paper presents an approach to the modelling of a cyclic battery tester and contains observations about lithium-ion (Li-ion) batteries, charging/discharging procedures, conditions and protections which must be observed during the testing process. The main goal was to create and simulate a schematic which will be capable of cyclically testing Li-ion battery cells. Regulation of the final schematic is based on cascade connections of operation amplifiers, which work as a voltage source with current-limiting functions. The power part is created by two MOSFETs connected as a half-bridge. This topology allows current to flow in both directions (from and to the battery). Final simulation is supplemented by protections such as reverse polarity protection, short circuit protection and overvoltage protection during charging. Proper operation of the whole connection is demonstrated by the simulation outputs in the final section.

    Opis:
    The dynamic growth of mobile technologies is a driving need for portable power sources. The most popular division of electrochemical cells relies on the type of chemical reaction within the cell. Current data coming from the Polish market show that despite the growth in the sale of secondary power sources, zinc-carbon and alkaline batteries are still the most popular. The results of non-reductive acidic leaching of zinc and manganese from the waste batteries stream have been presented. Manganese was leached with almost 100% yield in an experiment with a solid to liquid ratio equal to 4/1, pH of 1.04, and H2SO4 concentration of 72.5 wt. %. High yields were also obtained for zinc recovery from the waste stream (100% for two series with solid to liquid ratio 4/5, pH of 0.80; H2SO4concentration of 37.2 wt. %, and solid to liquid ratio 1/2; pH of 1.01; H2SO4 concentration of 27.3 wt. %). Besides, the quantitative and qualitative analysis of Zn-C and Zn-Mn batteries introduced to the Polish market and waste generated in the years 2010-2018 has been presented.

    Opis:
    The article discusses a method of assessing the of dependence of the number of batteries that would be needed to achieve energy balance in distributed generation systems with wind turbines on ambient temperature and on the error involved in predicting the parameters of wind flow (wind speed). To describe the relationship between current rate and capacity in a given current range, Peukert’s law is used. Dependence of the Peukert's constant on ambient temperature for the lead-acid battery HZB12-180FA is calculated. Taking the lead-acid battery and wind turbine VE-2 as a reference, dependence of area of controlled operation of the battery on the wind speed forecasting error is calculated. The technique of considering ambient temperature, depth of discharge, and wind speed forecasting error when deciding the size of energy storage of the balancing system (the number of batteries and their capacity) is provided. A family of curves representing the dependence of the number of batteries constituting the balancing system on the ambient temperature and the wind speed forecasting error are presented. It is shown that as the wind speed forecasting error increases from 0% to 15% and the ambient temperature decreases from 20 °C to 20 °C, the number of batteries should be increased by approximately 2.81 times in order to maintain the same area of controlled operation of a battery.

    Opis:
    In this paper, recovery of manganese and zinc from alkaline battery paste by leaching under atmospheric condition using elemental sulfur as a reductive agent and sulfuric acid was investigated. Different dissolution parameters, acid concentrations, liquid-to-solid ratios, reaction temperatures, leaching times and amounts of elemental sulfur were studied in detail. According to results, the Mn dissolution in reductive acidic media was an intermediate-controlled process with activation energy of 10.21±2.60 kJ/mol. After the leaching step, Mn and Zn were selectively precipitated from the leaching solution using sodium hydroxide. After solid/liquid separation, manganese(II,III) oxide (Mn3O4) was obtained by drying at 105 °C in air. Next, Mn3O4 was converted to manganese(IV) oxide (MnO2) by heating at 800 °C in air. After that the solution containing Zn(OH)42- was treated with sulfuric acid to form zinc hydroxide, separated and next converted to zinc oxide by heating at 600 °C in air. The final products were characterized by XRD. The results showed that the proposed process can be effectively used for recovery of Mn and Zn from alkaline batteries.

    Competitive flotation and solvent sublation of Zn(II) and Mn(II) ions from diluted, model and experimental, aqueous solutions (after leaching of spent Zn-Mn battery) by proton-ionizable lariat ethers in the presence of octylphenylodecyl (ethylene glycol) ether (Triton X-100) as a nonionic foaming agent were investigated. The influence of ether crown size variations (from DB-16-C-5 through DB-19-C-6 to DB-22-C-7) on separation of zinc(II) and manganese(II) ions as well as influence of structural variation within the collectors (identity of the pendent acidic group and lipophilicity) and pH of the aqueous solutions were presented. It was found that among seven tested proton-ionizable lariat ethers, the most effective removal of Zn(II) and Mn(II) ions from diluted aqueous solutions may be achieved with the use of sodium 3-[sym-(Decyl)dibenzo-22-crown-7-oxy]propane-sulfonate).

    Opis:
    The present work describes a control methodology for a hybrid energy storage system (HESS) to improve its transient performance under dynamic load conditions. The proposed coordination control enhanced life cycle performance by segregating the power between battery energy storage systems (BESS) and a supercapacitor (SC). The BESS and SC are connected parallel to each other, and two individual DC–DC bidirectional converters connect them to a common DC bus. The coordination control is established between the controllers of BESS and the SC of HESS, which helps to utilise the usable energy capacity of the HESS. The charging/discharging current of the BESS is controlled within the allowable safety range based on the slope and magnitude of the BESS current. The high-frequency power component is handled by the SC, which helps to reduce the extra exhaustion on the BESS during operation with a higher current. The proposed coordination control of HESS is validated through simulation and the results show the effectiveness of the proposed controller.

    This paper presents a novel concept of a circuit for voltage balance of three series-connected capacitors or batteries, as well as the research results. The problem is related to the control of voltage sharing on series capacitors, supercapacitors or battery banks in energy storage systems or direct current (DC)-link of four-level neutral-point-clamped inverters. The proposed circuit is a switched-capacitor (SC) resonant converter composed of a single capacitor and seven transistor switches. Control of the converter makes it possible to transfer energy between any capacitors, by switching selected transistors. This paper presents the basic concept of the converter, an analysis of control strategies and the simulation results for various cases of voltage balancing.

    Opis:
    This paper studies innovative application of sliding mode control (SMC) for a Hybrid Renewable Energy System (HRES) in grid-connected and autonomous modes of operation. The considered HRES includes a photovoltaic (PV), wind turbine (WT) based on a Permanent Magnet Synchronous Generator (PMSG). The PV generator is coupled to the common DC bus via a DC/DC converter. The latter is controlled by an MPPT algorithm based on the Adaptive Perturbation and Observation Algorithm Method (APOAM) to search the optimum working of this source. A SMC is utilized to manage the PV voltage to achieve the Maximum Power Point (MPP) by altering the obligation duty cycle. The battery interfaced by a bidirectional buck-boost DC/DC converter can be charged or discharged depending on the production situation. On the one hand, the wind turbine conversion chain is equipped with a PMSG and a rectifier controlled to regulate the operating point of the wind turbine to its optimum value. During a Stand-Alone Mode (SAM) operation, the Voltage Source Converter (VSC) was used for controlling the output voltage in terms of amplitude and frequency delivered to the AC load. However, in Grid-Connected Mode (GCM) operation, the VSC was adapted to control the electrical parameters of the grid. To better appreciate the advantages of the proposed SMC approach, we have proposed a series of comparative tests with the conventional PI control in the operating modes GC and SA and under different scenarios. The proposed control strategy has undeniable advantages in terms of control performance and very low total harmonic distortion THD value compared with the conventional PI control. Finally, It is concluded that the proposed approach improves the quality and provides a stable operation of the HRES.

    Opis:
    Over the past ten years, the automobile manufacturing basis has shifted to Thailand, thus transforming the country into an automobile industrial hub in Asia. An integral part of this industry, lead acid battery manufacturing has exhibited tremendous growth with increasing trends toward new manufacturing technology. This research aimed to study life cycle assessments of lead-acid automobile battery manufactured in Thailand by comparing conventional batteries with calcium-maintenance free batteries. Global warming and acidification are the largest environmental impacts associated with both battery types. Changing from conventional batteries to calcium-maintenance free batteries is able to reduce environmental impact by approximately 28% due to longer usage life and reduced utilization of manufacturing resources and energy. The greenhouse gases and acidification caused by one conventional battery amounted to 102 kg CO 2 and 0.94 kg SO2, respectively. These amounts decrease to 72 kg CO2 and 0.56 kg S02, respectively, when calcium-maintenance free technology is used. Raw material procurement is found to have the greatest environmental impact, followed by product usage. In this study, the information on environmental impact is incorporated with MET matrix principles to propose guidelines for environmental improvement throughout the battery life cycle.
