What is IEC 61851-3rd edition (2017)?

IEC 61851-3rd edition (2017) is an international standard that defines the technical requirements for electric vehicle charging equipment. It provides guidelines for the design, construction, and testing of such equipment to ensure interoperability and safety.

The Importance of IEC 61851-3rd edition (2017)

The third edition of IEC 61851 plays a crucial role in promoting the widespread adoption of electric vehicles (EVs) by establishing a common framework for charging infrastructure. This standard helps ensure that EVs can be charged safely and efficiently across different charging stations, regardless of the manufacturer or location.

Prior to the introduction of this standard, there was a lack of consistency among charging systems, leading to compatibility issues and potential safety risks. IEC 61851-3rd edition addressed these concerns, providing clear guidelines for the industry to follow.

Key Features of IEC 61851-3rd edition (2017)

The third edition of IEC 61851 includes several important features that contribute to the overall improvement of charging infrastructure:

Compatibility: The standard ensures compatibility between the charging infrastructure and electric vehicles by defining uniform electrical characteristics and communication protocols.

Safety: Safety is a key consideration in this edition, with stringent requirements for protection against electric shock, fire hazards, and other potentially dangerous situations.

Efficiency: The standard focuses on improving the efficiency of charging equipment, optimizing power transfer, and reducing energy losses during the charging process.

Interoperability: IEC 61851-3rd edition promotes interoperability by specifying common communication interfaces and protocols between the EVs and charging infrastructure.

Reliability: The standard sets performance criteria for both AC and DC charging modes, ensuring reliable and consistent charging capabilities across different systems.

The Impact of IEC 61851-3rd edition (2017)
