The rise of electric vehicles (EVs) has spurred significant advancements in charging infrastructure, including the development of specialized components designed to ensure the safe and efficient operation of charging stations. Among these components, relays play a critical role in managing the flow of electricity during the charging process. One such standard that defines the functionality and performance of relays in EV charging systems is IEC 61811, specifically focused on the EV Relay.

What is IEC 61811? IEC 61811 is an international standard set by the International Electrotechnical Commission (IEC) that outlines the requirements for relays used in various electrical systems. This standard is particularly relevant for electric vehicle (EV) charging stations, where relays are tasked with controlling the high-power electrical connections between the charging station and the vehicle’s battery. The IEC 61811 standard ensures that relays perform effectively under the demanding conditions of electric vehicle charging, guaranteeing both reliability and safety.
