The PET direct-mounted supercharging matrix integrates power electronic transformers, flexible charging stacks, and power electronic battery stacks. It features full-chain power electronics with direct medium voltage 10kV access, adopting an efficient DC architecture and a fully modular design that is both efficient and flexible. The charging power and terminal interface are designed separately, allowing charging power to be shared across various terminals. Energy storage and photovoltaic DC systems are seamlessly integrated to offer an extremely complete, simple, fast, and effective "four-pole" charging experience.
