A ProoV case study · educational project, not employment
Built a complete battery-passport compliance package for a single cell: classified regulated fields, separated public vs legitimate-interest vs restricted passport views, traced unresolved gaps to the supplier tier that owns them, and drafted targeted supplier requests to close the highest-priority missing data. Also computed the cell’s carbon footprint from a bill of materials and correctly concluded that sourcing decisions drive the largest share of emissions.
