Abstract: Using a self-developed economic model with a technical battery aging component, this paper provides a new approach to evaluating the economic efficiency of Li-ion battery storage. We use our model to quantify the increase in self-consumption of electricity from a solar photovoltaic system by means of a home battery storage system. Regarding battery aging, we find that the longest battery lifetimes can be achieved with the highest state-of-charge limit, which is, however, not economically efficient due to limited self-consumption. Although one of the three battery pooling concepts was identified as not being economically efficient, namely the case of Sonnen, our evaluation shows that economic efficiency can, in principle, be achieved with home battery pooling concepts. In future research, the model-based impacts on self-consumption and batteryaging found here ought to be validated by using real world data from the systems analyzed.
