What is IEC 60335-2-108:2020?

IEC 60335-2-108:2020, also known as "Safety of household and similar electrical appliances - Part 2-108: Particular requirements for electrochemical energy storage systems," is an international standard that focuses on the safety requirements for electrochemical energy storage systems used in household and similar appliances.

Scope of IEC 60335-2-108:2020

This standard applies to electrochemical energy storage systems (EESS) whose rated voltage does not exceed 250 V AC or 320 V DC. It covers a wide range of applications, including rechargeable batteries and capacitors used in household appliances such as vacuum cleaners, power tools, and gardening equipment.

The scope of IEC 60335-2-108:2020 also includes battery management systems (BMS) and associated electronic circuits used in EESS. It aims to ensure the safe operation of these systems by setting specific requirements for construction, performance, and protection against potential hazards.

Key Requirements of IEC 60335-2-108:2020

IEC 60335-2-108:2020 outlines several key requirements that manufacturers and users of EESS need to consider:

Protection against electric shock: The standard emphasizes measures to prevent electric shock hazards to users, including insulation requirements for conductive parts and the use of safety connections.

Overcurrent and overload protection: It specifies the maximum current limits that EESS should withstand without presenting a risk of fire or explosion. Overcurrent and overload protection mechanisms need to be implemented to ensure safe operation.

Protection against mechanical hazards: The standard addresses the risks posed by moving parts, sharp edges, and potential sources of injury during normal operation and maintenance of EESS.

Protection against thermal hazards: IEC 60335-2-108:2020 defines requirements for temperature control, heat dissipation, and insulation to prevent overheating and reduce the risk of fire or burns.

Compliance with IEC 60335-2-108:2020

Manufacturers looking to comply with IEC 60335-2-108:2020 should carefully evaluate their products and ensure they meet all the relevant requirements laid out in the standard. Testing and certification by accredited laboratories are typically required to demonstrate compliance.

For consumers, it is essential to look for safety markings or labels indicating that the appliance complies with relevant standards. This helps to ensure that the products they purchase have undergone rigorous testing and meet necessary safety requirements.

In conclusion, IEC 60335-2-108:2020 sets forth safety requirements for electrochemical energy storage systems used in household and similar appliances. It plays an important role in minimizing risks associated with electric shock, mechanical hazards, thermal incidents, and more. Adherence to this standard ensures the safe use of these appliances, providing consumers with peace of mind.
