When reviewing battery temperature uniformity, which information has to be tied to a specific vehicle?

Battery temperature uniformity has to be tied to individual vehicles. Each vehicle's temperature distribution sheet should trace to the individual measuring points, the ambient temperature, and the cooling state, and a batch summary cannot replace per-vehicle evidence. As long as readings taken right after a fast charge are being treated as a static condition and that has not been ruled out, the item is not ready for technical or documentary release. See this vehicle identity verification FAQ for guidance on managing battery temperature uniformity records by VIN.
