Start with the charger list
A useful intake starts with the physical inventory. Collect make, model, serial number, charger type, connector type, installation date, network provider, firmware version if available, and the billing method used at the site.
Prepare the field conditions
A test can be delayed by locked cabinets, blocked parking, unavailable network contacts, unclear pricing, or charger screens that are difficult to read. The best site hosts prepare access, photos, cones or traffic control, and a technical contact before the visit.
Keep a clean record
Site hosts should keep copies of prior repair notes, inspection notices, pricing screenshots, receipts, and any settings changes made before or after the test.
