EAX, an intelligent charging and swapping operations management platform developed based on IoT and big data technologies, innovatively integrates battery VR imaging technology to visualize the internal battery status through 3D modeling. Equipped with an AI diagnostic system, the platform analyzes battery state of health (SOH) in real time, predicts degradation trends, and simultaneously provides early warning of electrical and electrochemical failure risks. Integrating blockchain technology to build a trusted data chain for the entire battery lifecycle, it provides an accurate basis for residual value assessment and helps operators achieve efficient asset management.
