Title: What is BS EN 61800-9-2:2018 and How Does it Help?

Introduction

When it comes to the safety and reliability of electrical equipment, a relay is an essential component that ensures smooth operation and efficient power transfer. However, the selection of the right relay depends on various factors, including the specific application, the power requirements, and the environmental conditions. To ensure the quality and consistency of relays, various technical standards and guidelines have been developed. In this article, we will explore the technical aspects of the BS EN 61851-3:2018 standard and its importance in the field of EV charging infrastructure.

What is EN 61810-1:2020?

EN 61810-1:2020 is a widely recognized technical standard that sets requirements and provides guidelines for relay devices used in electrical equipment. Developed by the European Committee for Electrotechnical Standardization (CENELEC), the standard aims to ensure the safety and reliability of relays in various applications. It establishes consistent requirements for different types of relays, such as electromechanical, solid-state, or hybrid relays.

The primary purpose of EN 61810-1:2020 is to establish key requirements and guidelines for the design, construction, performance, and security of relay devices. By defining these requirements, the standard ensures that manufacturers produce reliable and compliant relay devices that meet specified performance levels.

Key Requirements and Guidelines

BS EN 61851-3:2018 is an international standard that specifies the requirements and testing methods for AC electric vehicle charging equipment. It covers both conductive charging systems (Mode 3) and wireless power transfer (WPT) systems. The standard provides guidelines for the design, construction, performance, and security aspects of charging stations.

Compliance with this standard ensures a consistent and safe charging experience for EV users across different systems and locations. The key technical requirements of EN 61851-3:2018 include:

Electrical Safety: The equipment must meet the requirements of IEC 61956-21 for electrical safety.

Environmental Resistance: The equipment must be capable of operating in various environmental conditions, including high temperature, low temperature, and vibration.

Overvoltage: The equipment must be able to withstand voltage levels that are not in accordance with the specified requirements.

Overcurrent: The equipment must be able to handle current levels that are not in accordance with the specified requirements.

Performance: The equipment must meet the specified performance requirements, including maximum current, voltage, and power.

Reliability: The equipment must be reliable and provide a continuous power supply to the connected devices.

Maintenance: The equipment must be designed for easy maintenance, including access to the connections and the ability to diagnose and repair any issues.

Conclusion

BS EN 61851-3:2018 is an essential standard for ensuring the safety and reliability of EV charging equipment. By defining key technical requirements and guidelines, the standard ensures that manufacturers produce reliable and compliant devices that meet the needs of EV users. Understanding the technical details of this standard is crucial for manufacturers, installers, and users of EV charging systems.
