Opis:: Article presents verification of LiFePO4 battery simulation model. Verification of battery model was made to assure real parameters of battery cells used for simulation. Simulation model of battery and test stand, similar to the stand used for test on a real battery, was designed in AMESim software. Data of the battery and single cell of battery characteristics were verified to assure true parameters for further tests of power transmission system of the vehicle. For verification theoretical model of the battery, real tests of battery discharging were performed in laboratory. Test stand used for battery discharging was build. Test stand was equipped in water resistor enable to set up various loads of battery. Electrical parameters of battery and battery cell were collected by voltage probes and current clamps and stored in database. Test was performed in similar condition, each time starting with fully loaded battery. Tests ends when battery management system shut down battery main switch. Tests conditions, virtual and real, were performed during similar battery load. Comparing data from unloading tests in laboratory enable to verify data of battery and battery cells designed in AMESim software. Such verification provide reliable model of the used battery. Model of the battery can be used in further simulation test of vehicle, where battery is installed.

Opis:: This article presents the influence of aging processes of the electric vehicle’s electrochemical battery. The increasing number of hybrid and electric vehicles increases the demand for durable and efficient sources of energy storage for vehicles. The vehicle's declared range is reduced over time. This is due to the aging of the battery that causes loss of its capacity and loss of its power. To minimize this phenomenon, manufacturers use counteracting solutions that include mounting additional cells in the battery that are switched on when the battery controller identifies a particular battery cell’s failure or high degradation. This is due to the deep and shallow discharges of the battery, the number of charge and discharge cycles, and the age and technology of battery packs. AMESim software was used for the simulation of the electric vehicle. The research was based on modelling the range of the vehicle whose cell capacity includes processes related to aging of the battery. An aging cell algorithm causes the capacity to drop and consequently reduces the range of one full charge. By modelling aging processes, it is possible to determine the battery’s probable capacity loss during vehicle use and to estimate how these processes affect the vehicle's range.

Opis:: Due to lack of practical energy sources – ones that are ecological, economic, portable and capable of being regenerated – storage is necessary in modern world for many areas of life to which people became accustomed. Development of many devices requires convenient electric power sources, often providing high currents and voltages, capable of ensuring large amounts of energy in short time. New technologies of lithium-ion cell batteries are a promising solution to this problem – current technologies are frequently inadequate – however they still require massive workloads in research, development, implementation to industry, and then to consumer market. Because of advancement in this area and evergrowing group of people interested in it is imperative to render an overview of the situation and knowledge of this topic. This article presents a review of most intensely studied cathode materials capable of providing high power, viable paths of improvement and short description of most important features of lithium-ion cells along with issues requiring solutions.
