CATL opens large-scale energy storage validation platform in Xiamen

The platform includes station-level grid integration testing, high-voltage safety labs, thermal safety and combustion testing, environmental reliability chambers, and electromagnetic compatibility facilities. CATL says the site can test more than 10 large-scale storage containers at the same time and simulate complex grid conditions. The launch matters because BESS projects are increasingly being financed and insured as critical grid infrastructure, where validated safety and performance data can affect bankability.
