What is OCPP?
OCPP stands for Open Charge Point Protocol. It is a communication protocol used between EV chargers and the software platforms that manage them. In practical terms, OCPP helps a charger talk to a charging network or charging management system.
OCPP can support functions such as starting and stopping sessions, reporting charger status, sending meter values, managing user access and updating charger settings. It is mainly used by charging operators, software providers, installers and infrastructure owners.
Why OCPP matters
For everyday EV drivers, OCPP is usually invisible. However, it matters because reliable charger communication can affect whether a charger shows as available, starts properly, reports faults and processes payments correctly.
On Penguin Power, OCPP is useful background knowledge for more technical readers and industry stakeholders. It connects to charger reliability, uptime, live status, remote diagnostics and network operations. A charging station may look simple on the outside, but software communication is a major part of the charging experience.
