Testing and certification at a glance
Certifying battery systems to meet regulatory standards involves a coordinated mix of electrical, mechanical, and safety testing. Depending on the application and target market, different standards may apply. We support and advise you through every step—tailored to your specific requirements:
- Battery cell testing
We test battery cells according to customer-specific requirements, focusing on key electrical parameters such as capacity, internal resistance, charge/discharge behavior, and thermal performance. - Standards-Based safety testing
We test battery systems for key safety parameters such as overcharge, short circuit, deep discharge, and thermal runaway. This is followed by preparation for UL2054 certification, which defines safety requirements for stationary and portable battery systems used in residential and commercial settings. We develop and test your solutions in accordance with these standards—ensuring a smooth market approval process in the U.S. - IEC 62133 Certification
IEC 62133 is the key safety standard for rechargeable lithium and nickel batteries used in device applications. It defines the electrical, thermal, and mechanical safety requirements—making it essential for international market approval. - UN38.3 Certification
Lithium-ion and lithium-metal batteries may only be transported by road, sea, or air if tested in accordance with UN38.3. The standard simulates real-world transport conditions—including low air pressure, temperature fluctuations, vibration, shock, short circuit, and free fall—to ensure that batteries can safely withstand these stresses. - Mechanical and environmental testing
Vibration, shock, drop, ingress protection, and temperature cycling—our tests are tailored to your specific application, whether in medical technology, aerospace, or other demanding fields. - EMC testing (Electromagnetic compatibility)
These tests ensure electromagnetic immunity and functional safety of battery systems in sensitive operating environments. System testing and final battery certification
The final approval stage includes system integration tests under real-world conditions, complete documentation, audit preparation, and delivery of all required certificates.All tests are conducted in close coordination with you—either in our in-house lab or with certified partner facilities.

Battery testing and certification—briefly explained
Battery system certification refers to the complete process from development and safety testing to approval for the intended target market or specific application areas (such as aerospace, medical technology, or robotics). The certification process includes compliance with international standards, transport regulations, and industry-specific requirements.
Before a battery system can be certified, the individual battery cells must first undergo testing. This includes assessing electrical properties (such as capacity and internal resistance), thermal behavior, and safety under load. Battery cell testing forms the foundation for subsequent system certification—preventing series defects and increasing operational safety.
UN38.3 is a mandatory certification for the global transport of lithium batteries, especially by air freight. The testing includes, among others, altitude (pressure) tests, temperature extremes, vibration, shock, and short circuit. Without successfully passing the UN38.3 test, no lithium battery may be shipped by truck or aircraft—regardless of its application.
This international standard applies to rechargeable batteries and battery systems using lithium or nickel chemistry. IEC62133 certification is required for products in medical technology, mobility, and information technology, among others. It assesses electrical safety, chemical stability, and mechanical durability.
This standard is primarily applicable in the USA and defines safety requirements for household and commercial batteries and accumulators. It tests behavior under conditions such as short circuit, overcharge, vibration, and temperature stress. UL2054 certification is often mandatory for products marketed in the US or used in safety-critical applications.
