What is IEC 62133: 2017/Amd.1: 2018 ?

IEC 62133: 2017-Amd1: 2018 is an essential international standard that outlines the safety requirements for portable secondary cells and batteries. The standard was first published by the International Electrotechnical Commission (IEC) in 2017 and has been amended multiple times to keep up with the evolving technology.

The primary purpose of IEC 62133: 2017-Amd1: 2018 is to ensure the safety of portable secondary cells and batteries used in various portable electronic devices. The standard provides guidelines and requirements to prevent potential hazards associated with these batteries, such as overheating, explosion, or leakage.

Key Safety Considerations

The standard emphasizes the importance of key safety considerations, including the design, manufacture, and testing of portable batteries. It also requires manufacturers to ensure that their products meet specific safety requirements, such as providing adequate performance and reliability, using appropriate materials, and implementing appropriate testing procedures.

Main Safety Requirements

IEC 62133: 2017-Amd1: 2018 outlines several key safety requirements for portable batteries, including:

Short-circuit protection: The standard requires manufacturers to implement short-circuit protection measures to prevent overheating and damage to the battery.

Overcharge protection: The standard recommends that manufacturers ensure that their products are capable of withstanding at least 1.25 times the maximum charge without causing damage.

Overcurrent protection: The standard requires manufacturers to implement overcurrent protection measures to prevent damage to the battery.

Discharge rate: The standard specifies the maximum discharge rate for portable batteries, which is the rate at which the battery can be discharged.

Recharge rate: The standard specifies the maximum recharge rate for portable batteries, which is the rate at which a battery can be charged.

Short-circuit protection during charging: The standard requires manufacturers to ensure that their products can withstand short-circuits during charging without causing damage.

Conclusion

In conclusion, IEC 62133: 2017-Amd1: 2018 is an essential international standard that outlines the safety requirements for portable secondary cells and batteries. The standard is widely used in the manufacturing of portable electronic devices, such as smartphones, laptops, power banks, and more. By implementing the guidelines and requirements outlined in the standard, manufacturers can ensure the safety and reliability of their products, thereby minimizing the risk of accidents or malfunctions.
