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.
Turning waste into power
RePurpose Energy aims to reduce battery waste by transforming used EV batteries into safe, affordable energy storage systems.
Founded by experts, backed by grants
Founded by UC Davis engineers, the company has secured over $9.99M in non-dilutive grants, major public sector support, and founder investment.
Commercial traction with global brands
The company delivered its first commercial unit to Nissan USA in 2024 and holds a feasibility study for second-life bus batteries.

Past Deployments
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.
Since 2024, our 360-kW / 1-MWh product has been operational at Nissan North America's Headquarters in Franklin, Tennessee.
Just deployed, our 60-kW / 200-kWh system, funded by the California Energy Commission is nearing final operational status. This system provides backup power and solar energy storage for a critical local healthcare facility in California.
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.
