Electric Vehicle’s battery presents a new transformation in the Electric vehicle and solar industries

As the globe’s interest in electric cars increases exponentially, a surge of recycled fuel cells whose output is no more adequate for automobiles needing productive efficiency and reach will eventually encounter sales. However, recent research says that such battery cells may still be able to provide a valuable and cost-effective sustainable alternative as a storage device for electricity-scale solar PV systems. Additionally, they can play a much less challenging role for over a decade. 

Six present and previous MIT scientists, along with Postdoc Ian Mathews, Professor Tonio Buonassisi, head of Photovoltaics Research Laboratory, have been involved in the analysis published recently in the Applied Electricity journal.

The research teams also analyzed a potential grid solar plant in California in-depth as a test study. The researchers investigated the economies of various outcomes: installing a solar plant alone for 2.5 megawatts, designing a new grid alongside a current battery storage network for lithium-ion and replacing it with a grid batteries built from repurposed electric power cells which had fallen to 80%.

The analysts noticed that the current design of the cells would not have a fair net financial return. A well-managed EV battery network may be a good, efficient investment as long as the cell’s price is under 60% of the initial cost.

One uncertain consideration is the duration of the cells in this second program will keep working effectively. The findings suggest that, after decreasing to 70% of their power rating from initial 80% (the stage in which they were stripped of EV usages), batteries should withdraw from the photovoltaic-farm backup services. Moreover, Mathews states, it could well be that it may be healthy and profitable to start working until 60%, and even below. For that to be decided, long-term pilot research is needed. Many producers of electric vehicles are beginning to perform these pilot testing. 

 Mathew describes that the actual economy of a proposal may differ significantly according to national regulatory and frequency-setting systems. For instance, specific municipal laws require storage costs for rate-setting, while some fail to include them in the total value of additional clean energy production. Since the economy of such structures is unique to the location, the research project in California intends to illustrate it from the United States. 

The next move Mathew states, ‘There are several suppliers to be involved: you’ve got a supplier of the EV’s, a lithium acid battery’s maker, the solar project’s manufacturing firm, the energy-electronics people.’ The goal, he says, ‘we want it to function technologically, economically,’
