Abstract

Aims: To investigate the viability of using second life electric vehicle batteries as ‘buffer packs’ for localized, in home storage of renewable energy. To investigate the potential value of such energy storage in terms of reducing energy bills. To investigate the effect, if any, of social group on energy demand patterns and the subsequent effect on buffer packs.
Methodology: Energy data was collected from 15 households and a representative daily demand pattern was formed from each. The availability of solar power was calculated based on standard assumptions regarding UK household installations. The flow of energy between the supply grid, renewable sources (i.e. solar panels) and a 10kWh battery storage system (the ‘buffer pack’) were simulated on a minute by minute basis allowing the savings in power drawn from the grid to be calculated.
Results: The simulation has indicated that the use of buffer packs has the potential to greatly increase the utilization of locally generated renewable energy. In some cases the stored energy removed the need to draw any power from the grid. The value of energy storage of this type has been estimated at approximately £250.
Conclusion: Buffer packs have substantial potential to increase the degree of utilization of renewable energy sources. However the financial viability of such systems remains questionable, even when utilizing second-life electric vehicle batteries. Further work is recommended to address some of these issues and, in particular, to investigate the effects of seasonal variations in energy use and renewable energy availability on buffer pack applications.
