recently, the energy storage testing center of the central research institute of the state power investment group has obtained the laboratory accreditation certificate issued by the China national accreditation Committee for conformity assessment (CNAS), which indicates that the energy storage testing center has established a laboratory management system that meets the "general requirements for testing and calibration laboratory capabilities" ISO/IEC 17025:2017 international standards, and its hardware facilities, management level and technical capabilities have all met the requirements of internationally recognized standards, the test report issued by the global authority and credibility.

As the first comprehensive laboratory in the group that integrates energy storage detection, operation monitoring, intelligent operation and maintenance, and safety evaluation, the energy storage testing center has a high-quality team composed of 18 professional and technical personnel, accounting for more than 90% of the professional and technical personnel, and has set up a comprehensive testing experimental platform covering electrical performance testing, battery management system (BMS) sampling testing and new energy grid-connected testing.

This time, CNAS has been approved, making the energy storage testing center the first laboratory in the group to obtain this qualification in the field of new energy grid-connected testing. Its approved grid-connected detection capability covers the voltage level of 6 kV to 35 kV. Relying on advanced mobile grid-connected detection devices, it can provide authoritative and compliant grid-connected performance verification for new energy and energy storage power stations. The establishment of this key capability not only fills the technical gap within the group, but also ensures the safe and stable access of large-scale new energy and energy storage systems to the power grid, providing solid technical support.
