Safely and conveniently store energy

Energy storage systems consist of equipment that can store energy safely and conveniently, so that companies can use the stored energy whenever needed. Energy storage systems are reliable and efficient, and they can be tailored to custom solutions for a company’s specific needs.

Benefits of energy storage system testing and certification:

  • Gain access to global markets
  • Assure the safety of your energy storage systems
  • Ensure quality and sustainability for future generations
  • Enhance your brand reputation

We have extensive testing and certification experience. Our testing laboratories are A2LA and ISO/IEC 17025-accredited, and our global expertise enables us to support clients worldwide. Our experts are knowledgeable about the relevant standards, and they can guide you through the energy storage system testing and certification process. We also deliver ESS testing and certification services faster than our competitors, so you can reap the benefits of energy storage testing and certification sooner.

Energy storage system testing capabilities

We provide a range of energy storage testing and certification services. These services benefit end users, such as electrical utility companies and commercial businesses, producers of energy storage systems, and supply chain companies that provide components and systems, such as inverters, solar panels, and batteries, to producers.

For end users/producers, we can test against the following standards:

For producers, we can test against the following standard:

  • UL 9540A – Standard for Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems

For suppliers, on our A2LA or ISO 17025 scope, we can test against the following standards:

  • UL 1973 – Standard for Batteries for Use in Stationary, Vehicle Auxiliary Power and Light Electric Rail (LER) Applications
  • UL 1642 – UL Standard for Safety Lithium Batteries
  • IEC 62619 – Requirements for Secondary Cells and Batteries for use in Industrial Applications
