OCPP vs OCPI: Which Protocol Does Your Project Need?
Understand where OCPP and OCPI belong, how charger operations connect to roaming services, and what to verify before choosing an integration architecture.

Explore. Understand. Connect.
A focused collection from the Charge Journal.
Read about the practical lifecycle of charging: sessions, scheduling, status, integration recovery, and the cost of maintaining useful information. These resources connect engineering choices to the behavior a person sees when charging does not follow the ideal path.
Model requested actions and observed outcomes separately. The articles in this collection help you plan for interrupted sessions, missing updates, and constraints that a simple success flag cannot adequately describe.
