On first hand, traction batteries represent the main cost of an Electric Vehicle (EV, up to 25% of the whole vehicle). Moreover, this application requires very high performances and so, the lifetime in an automotive context is shorten (end of life criteria is a capacity fade at 80% of the initial value according to IEC 62660-1 and ISO 12405-1 Standards).
On second hand, the key problem with the renewable energy generation sources is that the output power is intermittent in nature (including solar and/or wind). This fluctuation affects the grid stability and reliability. Consequently, Electrical Energy Storage (EES) has been recognized as one of the most promising approaches for increasing grid efficiency, voltage stability, and reliability, especially for optimizing power flows and supporting the renewable energy generation sources.
EVs on the roads are increasing due to their environmental benefits and their positive impact, as a flexible load, on the electrical grid management by contributing to integrate renewables fluctuations. Simultaneously, the need of periodically replacement of the vehicle battery to do not affect its performance, will lead to many batteries available in the upcoming years. Furthermore, technics to extend the life of used EV batteries exist and can be implemented to attain a better efficiency in these systems. In fact, commercial solutions for the reuse of batteries have been announced. But at the same point in time, it is worse to question what is behind the hype of “second use”. Why should batteries with 80% remaining capacity get removed from the electric vehicles? Are people willing to buy a maybe 8 years old battery with lower safety standard compared with new batteries which in addition have achieved cost reductions in the meantime? How much “second use” capacity can the stationary market absorb? And finally, how much transaction cost for converting and selling the vehicle batteries to the stationary market would be acceptable.
Due to different mass and volume constraints, the requirements of stationary applications are less harsh with regard to temperature ranges and peak currents than the automotive ones but the average number of daily cycles is significantly higher. Therefore, using EV batteries in stationary application as a second life is very promising but face many issues (safety, lifetime, cost). The objective of this Special Issue/Section in the Journal of Energy Storage is to promote excellence research concerning all aspects in the field of second life of electric vehicle batteries in stationary applications, focusing on state-of-the-art researches, developments and new trends.
This special issue proposes to tackle the different dimensions and pros and cons of the theme, from the vehicle life to the stationary life. Potential topics include but are not limited to the following:
- Ageing of batteries,
- State of Health estimation,
- End of Life criteria definition for second life batteries,
- Design methodologies of the second life battery system,
- Architecture of the second life battery system,
- Management of the second life battery system,
- Safety risks of aged batteries
- Balancing systems for the cells, the batteries and the packs,
- Technic-economic and market analysis,
- Life cycle assessment of second life battery applications,
- Market volumes for second life batteries,
- Alternatives for ageing vehicle batteries beside the stationary market
