Three positions that shape the work.
Battery performance is coupled.
Load, heat, cell behavior, power electronics, controls, enclosure design, and operating context belong in one risk picture.
QA/QC is engineering memory.
Inspection records are useful when they connect deviations to owners, closure evidence, and acceptance decisions.
AI must improve an engineering decision.
Diagnosis, sizing, forecasting, simulation, and traceability matter more than surface-level automation.
