Improved grid utilization, resulting from EV charging management combined with a solar-powered “second life” battery system, is expected to reduce stresses on the grid and reduce the need for additional peaker plants, thus reducing consumer costs while supporting the integration of renewable energy.

The program also includes a “second life” for used MINI E batteries, by repurposing these batteries into a stationary solar-powered electric storage system located at the BMW Technology Office in Mountain View, California. Grid efficiency through managed charging, combined with a used EV battery “second-life” system.

Classification of potential electrical storage for stationary applications. For example, they note, to regulate frequency, the energy storage capacity may not need to be long-lasting—minutes can be sufficient—but it must have a long cycle life because the system is likely to encounter multiple daily discharge events.
