The new-energy vehicle technical advisor can lead it. The handover material should cover the old and new identifiers, the installation date, and the software matching, and should name the provider, the person who confirmed it, and the confirmation time. Registration, certification, and filing requirements for replacement battery identity in the destination country follow local competent-authority rules, licensed-body review, and the applicable contract terms. See this procurement FAQ for the prior check on supplier and vehicle records for replacement battery identity. Copy the replacement battery identity material to the next batch only after this batch's version is confirmed, so that the error does not spread. For a review of the evidence needed for replacement battery identity, send the destination, model, and volume through WhatsApp.
