When conducting battery internal resistance testing, it’s essential to adhere to relevant regulations and standards to ensure accurate measurements and compliance with safety and quality requirements. Here are some key regulations and standards to consider:
- IEC 62133:
This standard specifies safety requirements for portable sealed secondary cells and batteries, made of lithium-ion and lithium polymer chemistry, for use in portable applications. It includes requirements for testing internal resistance as part of safety assessments.
- IEEE Std 1188:
IEEE Standard for Stationary Battery Sizing, Testing, and Maintenance provides guidance on various aspects of stationary battery systems, including methods for testing internal resistance. Adhering to this standard ensures proper evaluation and maintenance of stationary battery installations. - ISO 12405:
This standard outlines test procedures and specifications for lithium-ion traction battery cells and modules used in electric vehicles (EVs) and hybrid electric vehicles (HEVs). It may include guidelines for internal resistance testing to assess battery performance and safety. - SAE J2464:
Recommended Practice for Electric and Hybrid Electric Vehicle Battery Systems Crash Integrity Testing outlines procedures for evaluating the crashworthiness of EV and HEV battery systems. While primarily focused on crash testing, it may also specify internal resistance measurement methods as part of battery characterization. - ASTM EIS Standards:
ASTM International develops standards for various testing methods, including electrochemical impedance spectroscopy (EIS), which is commonly used for internal resistance measurement. Standards such as ASTM EIS62660-2 provide guidance on EIS techniques for lithium-ion batteries. - Manufacturer Guidelines:
Battery manufacturers often provide specific instructions and recommendations for internal resistance testing of their products. Following manufacturer guidelines ensures compatibility with the battery’s design and specifications. - National and Regional Regulations:
Depending on your location and the intended use of the batteries, there may be national or regional regulations governing battery safety, performance, and testing procedures. It’s important to familiarize yourself with relevant regulations to ensure compliance. - Industry Best Practices:
In addition to formal regulations and standards, industry best practices established by trade associations, research organizations, and experienced professionals can provide valuable insights into effective internal resistance testing methodologies.
By following these regulations and standards, along with manufacturer guidelines and industry best practices, you can ensure that battery internal resistance testing is conducted accurately, safely, and in compliance with applicable requirements.Kongter is dedicated to different options of quick handheld tester for test of battery internal resistance/conductance to meet these different international and industrial standards.
