Rivian’s factory will soon be powered partly by old batteries from its own EVs

# Rivian's Old EV Batteries Get a Second Life Powering Its Factory Rivian is installing over 100 used batteries from its electric vehicles at its Illinois factory to store power and reduce electricity costs. The recycled batteries let the company charge when electricity is cheapest and take better advantage of renewable energy from its solar panels and wind turbine, ultimately helping lower the cost of making new vehicles.
