IEC 60068-2-14 Temperature Shock Testing for Automotive Batteries
The IEC 60068-2-14 standard is a cornerstone in the automotive industry, providing detailed guidelines for temperature shock testing. This testing procedure aims to evaluate the durability and reliability of automotive batteries under extreme temperature changes. The purpose is to ensure that these critical components perform consistently across a wide range of environmental conditions encountered during use.
Battery performance under temperature stress can significantly impact vehicle safety, functionality, and longevity. Automotive manufacturers rely on stringent testing protocols like IEC 60068-2-14 to meet regulatory requirements while also ensuring product quality. This standard defines the test parameters for thermal cycling between specified minimum and maximum temperatures within a controlled environment.
The testing process involves subjecting batteries to rapid temperature changes, which simulate real-world conditions such as sudden cold snaps or heatwaves during transportation or operation. The goal is to assess whether the battery can withstand these shocks without failing or compromising performance.
For accurate and reliable results, specimens must be prepared according to specified guidelines in IEC 60068-2-14. Proper specimen preparation ensures that the test conditions accurately reflect real-world usage scenarios. This includes ensuring the battery is fully charged before testing, as a discharged battery may not provide an accurate representation of its capabilities.
The testing apparatus used for this procedure typically consists of a temperature-controlled chamber capable of rapidly cycling between defined minimum and maximum temperatures. The system must be equipped with sensors to monitor the temperature accurately and ensure it stays within specified limits throughout the test duration.
Testing according to IEC 60068-2-14 involves subjecting batteries to multiple cycles between the defined extremes, often following a predefined schedule. Each cycle consists of gradual heating or cooling until reaching the set temperature, holding for a period, and then rapidly returning to the other extreme.
During each test run, detailed data on temperature changes, duration at each stage, and battery performance is recorded. This comprehensive dataset allows manufacturers to evaluate how well their products perform under these harsh conditions. The results provide valuable insights into potential areas for improvement or optimization of product design.
The acceptance criteria specified in IEC 60068-2-14 outline the acceptable limits within which a battery must operate successfully during testing. These criteria vary based on specific requirements set by manufacturers, but generally include aspects like internal resistance measurement, voltage drop, and overall functionality after exposure to extreme temperatures.
| Temperature Range | Cycling Schedule | Data Collection Points |
|---|---|---|
| -40°C to +125°C | Multiple cycles between defined extremes | Temperature, Voltage, Internal Resistance |
