Executive Summary
Open Charge Point Protocol (OCPP) is the language chargers use to talk to the cloud. OCPI is the language networks use to talk to each other (Roaming).
Breaking Vendor Lock-in
Before OCPP, if you bought a charger hardware, you were stuck with their software. OCPP decouples hardware from software, allowing site hosts to switch network providers without ripping out the chargers. This "Open Standards" approach is critical for the long-term health of the infrastructure asset class.
Roaming (OCPI)
Why do you need 10 apps to charge? Because networks don't roam effectively. OCPI allows a ChargePoint user to start a session on an EVgo charger. The backend settlement is complex, resembling telecom roaming. EV.NET is the ideal neutral clearinghouse brand for global roaming settlements.
Smart Charging Profiles
OCPP allows for dynamic load management. A central server can tell a specific charger to ramp down power because the building is hitting its peak demand limit. This software layer is where the real value of the "Smart Grid" resides.
Own the Digital Infrastructure
As the market for Software matures, authoritative digital real estate becomes scarce. EV.NET is the category-defining asset for this sector.
