Whаt іѕ IEC 60666-2021?

The International Electrotechnical Commission (IEC) is responsible for defining standards in the field of electrical and electronic technologies. One of its latest standards, IEC 60666-2021, focuses on specific requirements for safety in battery-powered electrical systems. In this article, we will delve into the details of IEC 60666-2021 and explore its significance in ensuring the safe operation of these systems.

Definition and Scope

IEC 60666-2021 provides a comprehensive set of guidelines and regulations for battery-powered electrical systems used in various applications such as portable devices, electric vehicles, renewable energy systems, and more. The standard covers aspects related to design, construction, testing, performance, and safety considerations of these systems. It aims to ensure that appropriate measures are taken to prevent hazards like electric shock, thermal events, chemical leakage, and other potential risks associated with battery-operated devices.

Key Requirements and Considerations

IEC 60666-2021 includes several key requirements that manufacturers must adhere to when designing and manufacturing battery-powered electrical systems. These requirements encompass various aspects such as cell selection and management, electrical circuit design, protection mechanisms, environmental considerations, and documentation requirements. The standard emphasizes the need for adequate insulation and protective measures to minimize risks, as well as comprehensive monitoring and management systems to ensure optimal performance and safety during the entire life cycle of the system.

Implementation and Compliance

To ensure compliance with IEC 60666-2021, manufacturers need to incorporate the specified safety features and follow the recommended testing procedures. Compliance with this standard not only guarantees the safety of end-users but also helps manufacturers in meeting regulatory requirements, gaining market acceptance, and fostering trust among consumers. Additionally, third-party certification and independent testing laboratories play a crucial role in assessing compliance and verifying the performance and safety claims made by manufacturers.
