RePurpose Energy, headquartered in Fairfield, CA, focuses on reusing EV batteries to create reliable, low-cost second-life energy storage systems. Its 90-second diagnostic technology, built on machine learning, determines a battery cell’s state of health with less than 1% error, and its hand-held reader pulls data directly from out-of-vehicle packs. Dismantlers can decide between reuse and recycling in minutes. The company established a demonstration energy storage unit at UC Davis in 2018 and delivered its first commercial energy storage unit to Nissan USA in 2024. It is the first U.S. company certified to UL 1974 for repurposed batteries and is close to completing UL 1973 certification for its energy storage systems. RePurpose Energy is seeking partnerships with Michigan OEMs, battery collectors, and dismantlers to license its testing technology, jointly build energy storage systems and identify a potential in-state site.
