Battery testing services

The sporadic nature of many renewable energy sources make batteries an essential part of “always-on”, green electricity networks. But authorities, network operators and consumers need to be sure those batteries are reliable and safe. DNV GL’s standards-based battery testing services help you ensure your chosen battery solution operates correctly and safely in all conditions.

Our independent testing covers the full range of battery technologies: from single cells to complete systems with cycle capacities up to 2 MW. We offer both in-field testing and lab-based testing at our KEMA Laboratory USA (Chalfont) and BEST Test and Commercialization Center (BEST T&CC) facilities. Components are tested according to relevant international standards.
