Establishes "Electric Vehicle Battery Repurposing Fund" to support repurposing, remanufacturing, and recycling of electric vehicle batteries; dedicates amounts based on certain sales of electric vehicles.

S 644 establishes New Jersey's "Electric Vehicle Battery Repurposing Fund" in the state's General Fund, funded by $500 per retail electric vehicle sale reported annually. The fund supports repurposing (using old EV batteries for stationary storage like home energy systems), remanufacturing (restoring batteries to like-new condition), and recycling of EV batteries in an environmentally safe way. It directly affects electric vehicle owners (through the sales-based funding) and businesses handling battery processing. The bill aims to prevent toxic landfill contamination from batteries containing lithium, cobalt, and graphite as EV adoption grows in the state.
