Six things every operator should know about OCPP 2.0.1

Device model, security profiles and smart charging: what actually changes for operations teams.

1. The device model

Components and variables replace flat configuration keys.

2. Security profiles

TLS with client certificates is now first-class.

3. Transactions

One TransactionEvent message replaces Start, Stop and MeterValues.

4. Smart charging

Profiles are richer, and external limits are explicit.

5. ISO 15118

Certificate handling for Plug & Charge is built in.

6. Migration

You can run 1.6J and 2.0.1 side by side on the same platform.
