Reuse of Electric Vehicle Batteries for Solar Energy Storage
Repurposing used EV batteries as energy storage for PV systems.
Projects Updates/The Results
This agreement was formally executed on October 15, 2020, and held its kick-off meeting on November 3, 2020.
RePurpose Energy is conducting a series of laboratory-based cycling tests to identify the degradation rate and effective useful life of individual used EV battery cells based on a variety of control strategies. The team is creating a scale model of a second life EV storage system connected to a grid emulator to validate the optimal control strategy for a solar PV and energy storage system. Finally, the team is taking the learnings from the laboratory testing and deploying a full-scale demonstration installation to collect data on actual system performance. The demonstration site showcases resiliency and cost benefits to the identified business and local economy.
The solar PV and batteries will reduce energy costs via on-site generation and time of use arbitrage, demand charges via peak load reduction and shifting, and greenhouse gas emissions via reduction in on-peak energy demand. The b
The team will subcontract with a local solar installer to deploy the onsite renewable generation and energy storage, thus spurring economic development in a low-income community.
Environmental & Public Health
The site will achieve greenhouse gas reductions via installation of rooftop solar PV and second-life EV batteries. RePurpose estimates that the solar + storage microgrid will reduce the site's carbon footprint by about 62,000 kg/
This project aims to deliver greater electricity reliability to the host site and its local community by providing backup power in the event of an unplanned outage or public safety power shutoff (PSPS). In 2019, many PG&E custome
