We make lithium ion batteries a sustainable solution.
Many electric vehicle (EV) batteries can be reused before recycling. RePurpose Energy is focused on reusing EV batteries to create reliable, low-cost “second-life” energy storage systems. In doing so, we maximize the value of these batteries, strengthen the resilience and sustainability of battery supply chains, and support the global transition to renewable energy.
A circular economy for electric vehicle batteries.

Past deployment
Since 2019, our 60-kW / 275-kWh demonstration composed of Nissan LEAF battery modules has been operational alongside rooftop solar PV at the Robert Mondavi Institute in Davis, CA.
Battery Fire Prevention
We designed and demonstrated a patent-pending, non-destructive battery fire prevention system suitable for use in both energy storage systems and electric vehicles.
Certification in Process
With support from CalSEED, we are engaging with a nationally recognized testing laboratory to gain groundbreaking certifications for our repurposing process and second-life battery product.
Testing Technology Breakthrough
Thanks to an award from the National Science Foundation, we developed artificial intelligence to quickly, accurately, and cost-effectively measure used battery health.
Microgrid in Development
With $3 million in grant funding from the California Energy Commission, we are designing and building a solar PV + second-life battery microgrid.
