What is EN 61851-1:2020?

EN61851-1:2020, also known as IEC 61851-1:2020, is an international technical standard that defines the requirements for electric vehicle (EV) charging systems. This standard covers various aspects of EV charging, including safety requirements, communication protocols, and charging modes.

Safety Requirements

Safety is of paramount importance when it comes to EV charging. EN61851-1:2020 outlines stringent safety requirements that must be met by EV charging systems. These requirements include protection against electric shock, prevention of overheating, overcurrent protection, and insulation monitoring. By adhering to these safety standards, EV manufacturers and charging station operators can ensure a safe and reliable charging experience for users.

Communication Protocols

One of the key features of EN61851-1:2020 is its emphasis on standardized communication protocols. These protocols enable seamless communication between the EV, the charging station, and the utility grid. The standard specifies the use of protocols such as Mode 3 and ISO/IEC 15118 for exchanging information related to charging rates, billing, and grid integration. By adopting standardized communication protocols, interoperability between different EVs and charging stations can be achieved, allowing for greater convenience and flexibility for EV owners.

Charging Modes

EN61851-1:2020 defines various charging modes that cater to different charging scenarios. Mode 1 refers to charging using a standard domestic power outlet, while Mode 2 involves the use of an EVSE (Electric Vehicle Supply Equipment) with built-in protective functions. Mode 3, on the other hand, utilizes specially designed charging cables and connectors, ensuring safety and efficient charging. Additionally, the standard introduces Mode 4, which covers high-power DC charging using specialized charging equipment. These charging modes provide options for EV owners, catering to their specific charging needs.

Conclusion

EN61851-1:2020 plays a crucial role in establishing global standards for EV charging infrastructure. By adhering to this technical standard, manufacturers and service providers can ensure the safety, interoperability, and efficiency of EV charging systems. As EV adoption continues to grow, the importance of standardized charging practices cannot be overstated. EN61851-1:2020 paves the way for a future where EV owners can charge their vehicles reliably, conveniently, and safely, irrespective of the charging station or EV model they use.
