METHOD AND SYSTEM FOR USING SECOND LIFE BATTERIES AS ENERGY STORAGE IN A RENEWABLE ENERGY SYSTEM

A novel renewable energy system is disclosed. The renewable energy system combines second life electric vehicle batteries to form an energy storage system. The energy storage system may compensate for large variations in operational energy and power requirements. The energy storage system is enabled through reuse of unopened electric vehicle batteries after their end first life use (e.g., in automotive use). The energy storage system within the renewable storage system may include a plurality of second life electric vehicle batteries, which may be configured to controllably store and provide power for a variety of applications. In some embodiments, the energy storage system may be operably coupled to one or more photovoltaics, fast chargers, or other variable loads that operate on DC currents. In various embodiments, the renewable energy system containing the energy storage system may require only one bidirectional inverter, which may be connected to a grid.
