Part 3. IEC62133 Technical Specifications

Electrical Performance

  • Voltage and capacity: Batteries must meet specified voltage and capacity requirements to provide sufficient power for electronic devices.
  • Charge and discharge characteristics: Batteries undergo testing to evaluate their ability to charge and discharge safely and efficiently over their lifespan.
  • Cycle life: The number of charge-discharge cycles a battery can undergo while maintaining its performance within acceptable limits is assessed.

Mechanical Integrity

  • Physical dimensions: Batteries are measured to ensure they meet dimensional specifications and can fit appropriately into electronic devices.
  • Durability: Batteries undergo mechanical stress testing to evaluate their ability to withstand handling, transportation, and installation without damage.
  • Terminal integrity: We assess the integrity of battery terminals and connections to ensure secure and reliable electrical contact.

Safety Considerations

  • Overcharge and over-discharge protection: Batteries must have built-in protection mechanisms to prevent overcharging or over-discharging, which can lead to safety hazards.
  • Thermal stability: We evaluate the battery’s ability to maintain stable operation under various temperature conditions to prevent overheating and thermal runaway.
  • Short-circuit protection: Batteries undergo testing to ensure they withstand short-circuit conditions without causing safety hazards such as fire or explosion.

Part 4. IEC62133 Testing Procedures

The IEC62133 certification involves rigorous testing procedures to ensure the safety and reliability of lithium-ion batteries. Here are the critical testing procedures involved:

Mechanical Abuse Testing

  • Batteries undergo various mechanical stress tests, including crushing, puncturing, and impact tests.
  • These tests assess the battery’s ability to withstand physical damage and prevent hazards such as leakage or explosion.

Electrical Abuse Testing

  • Assessors evaluate the integrity of battery terminals and connections to ensure secure and reliable electrical contact.
  • The purpose is to evaluate the battery’s response to abnormal electrical conditions and prevent thermal runaway or fire.

Thermal Testing

  • We expose batteries to extreme temperature conditions, including high and low temperatures.
  • This testing determines the battery’s performance and safety across various environmental conditions.

Environmental Testing

  • Batteries undergo environmental stress testing, including humidity, vibration, and altitude tests.
  • These tests simulate real-world conditions to assess the battery’s durability and reliability.

Safety Performance Testing

  • Evaluators assess batteries for safety features such as built-in protection circuits and thermal shutdown mechanisms.
  • The testing ensures the battery can safely handle typical usage scenarios without harming users or devices.

Capacity and Performance Testing

  • Batteries undergo capacity testing to measure their energy storage capacity and performance over time.
  • This testing verifies that the battery meets specified performance requirements and maintains consistent performance throughout its lifespan.

Part 5. What battery types does IEC62133 cover?

IEC62133 covers a range of battery types, ensuring safety standards for various chemistries commonly used in portable electronic devices. Here are the battery types covered under IEC62133 certification:

Lithium-ion Batteries

  • These are the most common rechargeable batteries in electronic devices like smartphones, laptops, and cameras.
