EVSE Markings, Displays, Receipts, and Totalizers

Commercial charging should make the quantity, unit price, and total charge understandable. If the display is unreadable, the pricing path is unclear, or the receipt does not match the transaction, customer trust suffers.

Receipts, recorded representations, totalizers, audit trails, and photos help operators understand what was tested and what changed later.

Where applicable, security seals and audit trail information can matter because they help show whether metrologically significant settings were protected or changed.
