5/1/2023 0 Comments Battery pulse conditioning![]() ![]() Lead acid batteries are mostly used in the automobile industries, because of its high efficiency and low cost. Hybrid Electric Vehicle (HEV) technology is most upcoming in automobile industries, to reduce the pollution and fuel consumption. As shown in simulation results, self discharging is low and using low thermal flow mode, power loss of the battery is reduced which leads to more efficiency and more stable current and voltage in the battery output port. In addition, the analysis of cycle number, capacity and charging/discharging process is presented to provide clearer explanation of this battery behavior. The efficiency of lead acid battery based on the proposed model is shown in the simulation results. The effect of temperature in charging/discharging rate is also analyzed. In this paper, a new Finite-Element-Method (FEM)-based model using energy equations is proposed where simulation is done to present the performance of this battery in different conditions. Due to the complexity of the structure of lead acid battery, modeling and simulation of this element can be useful to diagnose its behavior and details of analysis in view of charging process, thermal effect and performance. From known batteries, Lead acid battery is attentional because of low cost, charging/discharging rate and efficiency while it is widely used in technical systems. Also, another goal is to analyze the electrical and thermal parameters of the designed battery pack and cell and suggest better solutions to make the wet battery cell maintenance free (no need of addition of water).īatteries are known as energy storage units relating between generators and consumers. Main goal of this paper is to design the suitable battery pack for UPS so that it can give maximum backup range to the computer within a certain economical range or cost limit. So, the most important integral part of UPS is the battery pack which is used as energy storage device in UPS. Batteries are used as energy storage device in UPS which store electric energy during charging state and discharge that electric energy during any kind of interruption to provide backup as additional power source for the computer. So, UPS broadly called an uninterruptible power supply device is used in computer to provide a backup power source which will maintain the consistency in voltage and flow of electricity which in turn will provide consistent power input. ![]() ![]() Those incidents have consequential effect on computer's hardware such as data losses, burning of sensitive equipment etc. Voltage interruption can be happened by several reasons like blackout, brownout, noise, spike etc. The percentage improvement in the capacity of the batteries is 89.5%, 75.9%, 1.6% and 1.4%, for batteries 1, 2, 3 and 4, respectively. The results show that the desulfation device works in desulfating lead-acid batteries as there are different degrees of improvement on the capacity of all the batteries. The desulfation experiment lasted for ten weeks but the batteries were tested to know their capacities after two, six, and ten weeks. The battery bank was connected to be charged at the same time by a photovoltaic system. Thereafter, a high-frequency pulse desulfator was connected to desulfate the battery bank consisting of the four batteries. Four fully charged 100 Ampere-hour Valve Regulated Lead-Acid Gel batteries were discharged with an electronic-load battery discharger to ascertain their capacities. This research, therefore, aims at empirically evaluating one of such products. But there are little or no systematic studies to evaluate the performance of these products to know whether they do what their manufacturers claim. Also, many products available in the market worldwide claim to use this technique to effectively desulfate lead-acid batteries that deteriorate due to sulfation. There are patents on the use of high-frequency pulse desulfators to desulfate lead-acid batteries. The major cause of deterioration in lead-acid batteries is sulfation. ![]()
