A sign-off-per-item method works well for PHEVs used without regular charging: procurement confirms engine and battery operating logic, the technical team confirms charging conditions the customer can actually get, and the delivery side confirms fuel economy, service and sales wording. If a PHEV is rarely charged, energy consumption and the customer experience drift away from the product's positioning, so check the charging conditions and explain the real usage pattern before selling. Log engine and battery operating logic first, then confirm charging conditions the customer can actually get; if fuel economy, service and sales wording changes, the earlier conclusion no longer applies.
