A common misreading
A frequent error is treating echelon use in isolation. Its result depends on coordination, and verifying small before scaling is the needed correction here at the very start of the work program.
Metrics and stages
Utilization and coordination outrank capacity. Turning cases into mechanism speaks louder than dazzling demos. Feasibility first, stability in rollout, efficiency when mature, across diverse Yantai districts and their many sites.
A comparison lens
Compare paths by maturity, local fit, cost standard alignment, and daily impact. Pace matters more than speed; verify then expand the echelon use program so the batteries stay safe through their entire second life of service.
Reach echelon use daily through a checklist that verifies small then scales. Turn cases into a mechanism. In Yantai we compare by maturity and fit and expand carefully, so the second life batteries stay safe through their service and the checklist becomes the habit that keeps the program honest each week. Small repeats beat one grand attempt that skips the lesson.
