EN 61851-2:2020 is an internationally recognized standard that specifies the requirements and test methods for electric vehicle charging systems. This comprehensive technical document outlines the safety, functionality, interoperability, and performance criteria for EV charging infrastructure.
of EN 61851-2:2020
The standard provides guidelines for both AC (alternating current) and DC (direct current) charging modes, ensuring compatibility with different types of electric vehicles. It defines various charging levels, communication protocols, and connectors to facilitate smooth and efficient charging operations.
EN 61851-2:2020 covers different aspects of EV charging infrastructure, including:
Charging modes: The standard specifies three modes of EV charging - mode 1, mode 2, and mode 3. Each mode represents a different level of charging power and safety features. Mode 3, for example, involves using a dedicated charging station with robust safety mechanisms.
Connectors and cables: To promote interoperability, the standard defines several types of connectors and cables. These include Type 1 and Type 2 connectors for AC charging and CCS (Combined Charging System) for DC charging. The standard ensures that all connectors adhere to strict safety and performance requirements.
Communication protocols: EN 61851-2:2020 also establishes guidelines for communication between the electric vehicle, charging station, and back-end systems. This allows for effective monitoring, control, and billing of the charging process. Common communication protocols specified in the standard include ISO/IEC 15118 and OCPP (Open Charge Point Protocol).
Benefits and Impact of EN 61851-2:2020
The implementation of EN 61851-2:2020 brings several benefits to the electric vehicle industry and stakeholders:
Safety: The standard focuses heavily on safety aspects, ensuring that EV charging systems meet stringent requirements to protect users, vehicles, and infrastructure. This promotes confidence in the reliability and security of electric vehicle charging.
Interoperability: By defining common connectors, cables, and communication protocols, EN 61851-2:2020 fosters interoperability among different manufacturers and service providers. This means that electric vehicles can charge seamlessly at various charging stations, regardless of the brand or supplier.
Efficiency: The standard encourages the use of efficient charging methods and technologies, such as high-power DC charging. This reduces charging time and enhances the overall user experience, making electric vehicles a more convenient alternative to traditional internal combustion engine cars.
In conclusion, EN 61851-2:2020 is a vital technical standard that plays a crucial role in the development and deployment of electric vehicle charging infrastructure. Its comprehensive guidelines ensure safety, compatibility, and efficiency across different types of charging modes, connectors, and communication protocols. By adhering to this standard, stakeholders can contribute to the growth of electric mobility by offering reliable, interoperable, and user-friendly charging solutions.
