Battery testing

Ensure battery safety and reliability with development and validation testing to current and emerging standards

TÜV SÜD assists battery and electric vehicle manufacturers in meeting battery standards and demands required. As your trusted partner, we provide solid expertise and deep experience in battery testing to maximise the safety, reliability, performance and lifetime of your products. This creates greater confidence to fulfil your customers’ expectations, comply with regulatory standards and access markets, while reducing risks of costly product recalls. We support you in a variety of sectors including the automotive, rail, consumer goods, aviation, shipping and medical devices industries.

What is battery testing?

Today, battery technology is developing at a breath-taking pace. Nevertheless, your customers’ expectations for safety and quality are as demanding as always.
Battery testing addresses these by validating the safety and reliability of the batteries used in a growing range of applications. This includes batteries for transportation applications such as electric vehicles, rail, marine and aerospace, but also stationary batteries for grid storage and balancing, backup power applications and batteries for wireless equipment and medical devices.

Why is battery testing important?

Batteries must not pose any danger to people, not even under extreme conditions. They should therefore be evaluated thoroughly before being put into use with an effective set of battery tests. The tests ensure that batteries fulfil legal, industry and manufacturer requirements.

Working with TÜV SÜD as an expert partner to ensure the safety, reliability and consequently the quality of your battery type provides multiple benefits for you:

  • Stay ahead of the technological development with experts who are at the forefront of the battery industry.
  • Save time and money with reliable tests that reduce warranty claims, time to market and R&D activities.
  • Work with a single-source provider for testing and certification, supporting you through the entire value chain from component to final product.
  • Obtain battery certification that helps you to gain customer confidence by providing the best quality and safe batteries for various industries. 

TÜV SÜD is a leading global expert in testing battery cells, modules and packs

TÜV SÜD is your trusted and neutral third-party technical service provider for battery testing. Our holistic approach and commitment to safety will ensure the reliability of your battery. Our service portfolio covers battery tests for a host of different uses: from electric vehicles and off-road, e-bikes, aerospace, rail and waterborne transport to the extensive field of stationary energy storage systems, grid storage and uninterruptable power supplies (UPS). This versatility, combined with years of international experience, modern test equipment and highly competent experts, makes TÜV SÜD the ideal partner for battery testing.

We test batteries at all levels, with tests in the electrical, chemical, corrosive, mechanical and abusive domain.

TÜV SÜD’s battery testing services

We offer battery testing services to ensure that your products meet the highest levels of quality and safety while ensuring compliance with relevant standards and regulations. Our battery testing services include:

Battery safety and battery abuse testing

Testing in extreme environmental conditions and beyond standard operating conditions helps you find out about product risks and enables more accurate risk assessments. This helps to find suitable countermeasures early enough in the development and avoid delays in the final phase of development.

Also, dynamic impact testing simulates a real vehicle accident to determine the true safety performance of the battery when the car body is deformed. TÜV SÜD can perform dynamic impact tests for electric vehicle batteries and provide advice on the optimum test design including impactor geometry.

Battery Performance and lifecycle Testing

We support you in verifying how your battery is performing against the specification, be it in terms of lifetime or in terms of the power output. Through this, you’re able to show the quality of the product to your customers and prove the efficiency of the battery system. Also, very high-power profiles can be implemented to validate fast charging or simulate some laps on the race track. Our battery tests include lifecycle testing, battery environmental cycle testing and battery calendar life testing. Our experts can customise the testing programmes according to your individual and specific customer requirements. 

Battery environmental and durability testing

We support you in demonstrating the quality and reliability of your battery. This helps you to evaluate the effect of external influences on your battery and prove performance under all circumstances by tests like vibration, shock, EMC, thermal cycling, corrosion, dust, salt and humidity tests.

Battery Certification and global market access

We support you in ensuring that your batteries can be transported safely and access markets worldwide according to the applicable legal requirements.

  • We conduct battery tests for the United Nations requirements (UN 38.3) for the safe transportation of lithium cells and batteries . In addition, we provide testing according to several safety standards (such as IEC 62133, UL 1642) and performance standards (for example IEC 61960-3).
  • We test your stationary batteries according to the special requirements towards safety, particularly for the European market, including the Low Voltage Directive (2014/35/EU), the EMC Directive (2014/30/EU) and the Battery Directive (2006/66/EC).
  • We conduct the approval tests required under ECE-R100.02 for the market access of electric vehicles in UNECE member countries and support you along the approval process.
