Key Field Judgments to Make for Charging Interoperability

A Constraint Often Underestimated

One constraint is easy to miss: a feedback loop drives improvement more than any single clever design. We value capabilities already proven in practice over concepts that look good in slides. Interoperability should be tested where it actually runs, because a standard that looks clean on paper can still fail at the connector in daily use.

Attention Shifts by Phase

Early stage watches feasibility, promotion stage watches stability, maturity watches efficiency as priorities rotate. Stages are not separate; preparation in one sets the ease of the next. We review at each boundary before moving on, so a weak pilot never quietly becomes a troubled district-wide rollout that nobody wanted.

From the User Backward

We reason backward from real experience rather than forward from the spec sheet. Handy, safe and supported outweigh any parameter that impresses at a demo. A beautiful number that fails daily use is decoration, not infrastructure. Four angles guide us together: supply cost, demand habit, service efficiency and policy rhythm, read as one picture.
