OCPP 2.0.1
Version 2.0.1 of the Open Charge Point Protocol (OCPP) that standardizes communication between charging stations and a Charging Station Management System (CSMS).
Technical Details
OCPP 2.0.1 replaces OCPP 2.0 with non-backwards-compatible schema fixes intended to prevent market confusion and interoperability issues. It strengthens cyber security (security profiles, certificate/key management, secure firmware updates, security event logging), formalizes an extensible Device Model for configuration/monitoring, and expands smart charging to include inputs from local controllers and external energy management systems.
Fleet Applications
Enables fleets to operate mixed charger hardware under one CSMS while improving security posture and day-2 operations (remote configuration, monitoring, and firmware management). Supports advanced depot smart charging setups and is a key building block for ISO 15118-based workflows such as Plug & Charge.
