Abstract

Batteries with 80% of their lifespan are increasingly discarded with the popularization of electric vehicles. The aim of the study is to evaluate the use of second life batteries from electric vehicles in residential photovoltaic prosumers systems. Thus, carrying out an investment feasibility analysis considering the changes proposed in the net metering tariff model in Brazil. The operating strategy for a prosumer is optimized, considering real data from a retired second life battery with 70% of its useful life and its degradation in the second life, this ranging from 60% to 50% of its useful life. Four study scenarios were considered according to the absence or presence of Net Metering and the conventional and white tariffs. The results show the attractiveness of this investment when considering the white tariff and the need to extend the battery life by up to 50% for the scenario with conventional tariff.
