Environmental testing of batteries

TÜV SÜD offers a wide array of different environmental battery testing services to support our customers in demonstrating product safety and gaining widespread acceptance of their traction batteries. We offer environmental tests against various international standards like ISO 16750, ISO 12405 and OEM specifications like LV124 standard.

WHAT IS ENVIRONMENTAL BATTERY TESTING?

Environmental testing simulates extreme environmental conditions that traction batteries encounter once in operation. The tests expose batteries to a variety of conditions such as heat, cold, corrosion and vibrations The batteries are assessed in test chambers designed specifically for environmental testing of batteries. They are subjected to an array of assessments, including humidity, thermal cycling, salt spray, vibration and shock testing.

WHY IS IT IMPORTANT TO CONDUCT ENVIRONMENTAL BATTERY TESTING TO STANDARDS LIKE ISO 16750?

Environmental tests ensure that batteries will be able to withstand 'real world' conditions during later use and fulfil the required quality and safety standards – in any use case, be it in electric vehicles, in mobile use or in stationary application.

There are several international standards such as ISO 16750, ISO 12405 and OEM specifications for environmental testing of traction batteries like the LV124 standard. The benefits of testing your batteries against these standards include:

• Demonstration of safety and reliability of your traction batteries by testing to relevant global standards.
• Being able to provide evidence to regulators and consumers that rigorous traction battery testing has been undertaken and ensure that your batteries will be able to withstand various environmental conditions during later use.
• Reveal design faults early in the development process with environmental testing for high-voltage batteries and avoid costly redesign and recalls at a later stage by early detection of potential safety gaps.

TÜV SÜD'S ENVIRONMENTAL BATTERY TESTING SERVICES

TÜV SÜD offers environmental testing for high-voltage batteries in accordance with an array of different international standards, including ISO 16750, LV 124 standard and ISO 12405. The batteries can also be actively operated, i.e., charged or discharged, during testing.

Amongst others, we can offer the following environmental tests for high-voltage batteries:

• Vibration and shock testing, with or without parallel temperature/humidity tests in simultaneous electric operation

• Thermal testing, including high-temperature, thermal shock and thermal cycling tests
• Ingress protection testing (IP testing), e.g. IP56 or IP65 via
  - Dust testing
  - High pressure jet testing
  - Splash water testing
  - Immersion testing (IPx7 and thermal-shock immersion)
• Humidity testing
• Thermal shock testing in dedicated chambers or with water to hot air change
• Altitude simulation/low-pressure testing
• Gravel impact/stone chipping testing
• Salt-spray testing
