CATL has opened what it describes as the “world’s largest and most comprehensive testing and validation platform for energy storage systems” at its headquarters in Ningde, China.
The facility, which CATL says spans over 100,000 square metres, is designed to simulate real-world operating conditions for battery energy storage systems (BESS) across multiple grid applications, including frequency regulation, peak shaving, renewable energy integration and black start capabilities.
The company said the platform can test systems ranging from individual battery cells to multi-megawatt containerised units, with the capacity to validate performance across temperature extremes, cycling patterns, and grid disturbance scenarios.
