What is BS EN 62722-2-2:2013?

BS EN 62722-2-2:2013 is a technical standard that plays a crucial role in ensuring the safety and efficiency of residential electric vehicle charging systems. The standard provides guidelines and requirements for the installation, operation, and performance of such systems. It focuses on various aspects, including protection against electric shock, usability, electromagnetic compatibility, and electrical insulation coordination.

Safety Requirements

One of the key objectives of BS EN 62722-2-2:2013 is to ensure the safety of the users and the surrounding environment during the charging process. The standard specifies strict guidelines for protection against electric shock, both by incorporating protective devices within the system and by implementing necessary earthing measures. It also addresses potential hazards related to overheating and fire risks, putting emphasis on proper thermal management and preventing the release of flammable materials.

Performance and Usability

Apart from safety, the standard also focuses on the performance and usability of residential electric vehicle charging systems. BS EN 62722-2-2:2013 sets requirements for the power supply capabilities of the system, ensuring that it can deliver the necessary charging current to meet the demands of various electric vehicles. Moreover, the standard provides guidelines for user interface design, accessibility, and physical protection of the charging equipment, aiming to enhance user experience and ensure convenience and ease of use.

Electromagnetic Compatibility and Insulation Coordination

To avoid interference with other electrical systems and to maintain its own reliability, an electric vehicle charging system must adhere to strict electromagnetic compatibility (EMC) requirements. BS EN 62722-2-2:2013 outlines criteria for electromagnetic emissions and immunity, ensuring that the system does not cause harmful interference to other devices or suffer from external electromagnetic disturbances. Additionally, the standard addresses insulation coordination to safeguard against electrical breakdowns and maintain the isolation between circuits, protecting both the equipment and individuals.
