European standard charging pile communication protocol
In Europe, electric vehicle (EV) charging involves several communication protocols, each playing a crucial role in different communication scenarios. Here are the main protocols and their applications:
Main Communication Protocols and Applications
ISO 15118
Application: ISO 15118 is used for communication between electric vehicles (EVs) and charging stations. It supports smart charging, Plug and Charge (PnC) functionality, and vehicle-to-grid (V2G) energy transfer. This protocol ensures the security and efficiency of both AC and DC charging sessions.
OCPP（Open Charge Point Protocol）
Application: OCPP is used for communication between charging stations and central management systems. It is a global open standard widely used to address communication issues across private charging networks, supporting remote control, firmware updates, and session management. OCPP is considered an industry standard for charging infrastructure interoperability. OCPP industrial routers act as a bridge to enable efficient communication between charging stations and operation management platforms.
OCPI（Open Charge Point Interface）
Application: OCPI facilitates information exchange between different charging networks, supporting roaming, authorization, billing, and real-time status updates. This allows EV users to seamlessly use different charging networks globally.
CCS（Combined Charging System）
Application: CCS combines AC and DC charging capabilities, primarily used for high-speed communication and high-power transmission between vehicles and charging stations. The CCS2 standard is widely used in Europe, supporting fast charging up to 350 kW.
These protocols ensure interoperability among different manufacturers and service providers through standardized communication methods, providing users with a convenient and efficient charging experience.
Supporting Standards
IEC 61851: Defines the conductive charging system for EVs, covering both AC and DC charging to ensure safety and interoperability.
IEC 62196: Defines the physical connectors used for EV charging, including the Type 2 connector widely used in Europe.
Other Protocols
Open Automated Demand Response (OpenADR): Used for demand-side management by communicating price and event messages between utilities and distributed energy resources.
Open Smart Charging Protocol (OSCP): Communicates predictions of locally available capacity to optimize the operation of charging stations.
These protocols are crucial for creating a cohesive EV charging ecosystem in Europe, ensuring interoperability among different manufacturers and service providers while providing users with a convenient and efficient charging experience.
