“…More results can be found in [33]. The results show that, as expected, the 500W power implies a cell life of 450 cycles, the end-of-life adopted criterion being reaching the lowest acceptable cell voltage.…”

This paper gathers experiences and results from several demonstration projects in the field of grid integration of electric vehicles. The analyzed research projects are selected among research institutes and universities that are part of the European Energy Research Alliance Joint Program on Smart Grids. The paper provides an overview of recent trends in the field of electric vehicles integration issues and then dives deeper into specific aspects of each project. Twelve research projects are presented in general terms, while detailed information can be retrieved from the references and the websites. Although each project has its focus, a common element that can be devised is that the charging process can be technically controlled based on different interests and algorithms, but its role in the market is still under development. Particular focus is always given to the behavior of the user, which ultimately determines the possible level of flexibility that the electric vehicle can provide to the grid.

“…The test setup was composed of a charging and discharging system driven by a Digatron ® battery cell tester and two thermostatic chambers, wherein the cells under testing were positioned, whose main characteristics are reported in Table A1 in the Appendix A [8][9][10]. A picture of the experimental setup inside the climatic chamber is found in Figure 2, while a picture of the laboratory is shown in Figure A1.…”

“…Since life tests last long period of time, typically months, an industrial device is needed in order to automate the test process, as well as to allow tests to be performed, without interruption, for several days or weeks. The considered test is shown in Figure 1a, and, as discussed earlier, is inspired by the common needs of an electric vehicle when charged for about 15 min [8]. All the aging tests are performed on single cells; therefore, the final results will also refer to the aging phenomena at the cell level.…”

Experimental Evaluation of Aging Indicators for Lithium–Iron–Phosphate Cells

Degradation mechanism of batteries has to be carefully studied when considering their utilization in electrical power systems. This paper presents the results of an extensive experimental campaign, through which three different lithium–iron–phosphate (LFP) cells were subjected to different electrical cycling stresses. The purpose of the campaign was to evaluate the cells’ aging, as well as to try to find parameters on the cell behavior before its end of life, able to act as state-of-life (SOL) (or aging) indicators. The considered stress consists of the cyclic repetition of fixed-duration discharge steps, followed by full charge phases. The three cells under study were subjected to the very same stress pattern but with three different discharge and charge power levels: low, medium, and high. The results showed that the end-of-discharge voltage and the cell internal resistance can be used as good SOL indicators. However, both are significant functions of the cell conditions, such as the state of charge (SOC) and the cell temperature.
