“…-Autonomous use: In this application, the batteries are charged by the RES but the whole system is connected to the grid, providing an energy support in case of a lack of generation from the RES (Guo et al 2014). In this case, the DOD of the battery will also be around 50%.…”

Nowadays, the electric vehicle is one of the most promising alternatives for sustainable transportation. However, the battery, which is one of the most important components, is the main contributor to environmental impact and faces recycling issues. In order to reduce the carbon footprint and to minimize the overall recycling processes, this paper introduces the concept of re-use of electric vehicle batteries, analyzing some possible second-life applications.\ud Methods\ud First, the boundaries of the life cycle assessment of an electric vehicle are defined, considering the use of the battery in a second-life application. To perform the study, we present eight different scenarios for the second-life application. For each case, the energy, the efficiency, and the lifetime of the battery are calculated. Additionally, and based on the global warming potential, the environmental impact of the electric vehicle and its battery on a second-life application is determined for each scenario. Finally, an environmentally focused discussion on battery electrodes and research trends is presented.\ud Results and discussion\ud For the selected scenarios, the second life of the battery varies from 8 to 20 years depending on the application and the requirements. It has been observed that the batteries connected to the electricity grid for energy arbitrage storage have the highest impact per provided kilowatt hour. On the contrary, the environmental benefit comes from applications working with renewable energy sources and presenting a longer lifetime. We pointed out that a correlation between cycling conditions and degradation mechanisms of the electrode materials is compulsory for proper use of the electric vehicle battery in a second-life application.\ud Conclusions\ud To limit the environmental impact, batteries should be associated with renewable energy sources in stationary applications. However, it is more profitable to re-use Li-ion batteries than to use new lead-acid batteries. Although many batteries applied for electric vehicles use graphite-based anodes, the latter may not be the most suitable for the second-life application. A better understanding of Li-ion battery degradation during the second-life application is required for the different existing chemistries.Postprint (author's final draft

“…[15,16]). In other works, small converter prototypes are interfaced with real time digital simulators achieving an hybrid configuration (the so called Hardware In the Loop technique) [17,18]. Nevertheless, the results of a validation on a full-scale, noinertia MG is still missing due to the limited number of facilities designed for research purposes.…”

The paper proposes a simple but effective model for no-inertia microgrids suitable to represent the instantaneous values of its meaningful electric variables, becoming a useful platform to test innovative control logics and energy management systems. The proposed model is validated against a more detailed microgrid representation implemented in the electromagnetic simulator PSCAD-EMTDC and then against experimental data collected on the University of Genoa test bed facility. Recorded data highlight a good trade-off in matching the results of the proposed model, confirming its suitability to be used for the preliminary testing of new control logics for islanded microgrids.

“…Battery reclamation and management is becoming an increasingly important issue [4]. On the other hand, although the retired batteries can no longer meet the high power/energy requirements of the EV, they can still be useful for less demanding scenarios, such as in domestic energy storage system (ESS) [5][6][7]. It is reported that after 8 years' EV service, the battery pack can still work as an ESS for more than 10 years together with household solar panels [8,9].…”
