The ChaoJi connector, also referenced as CHAdeMO 3.0, is a high-power charging standard for electric cars, released in 2020. The connector has a lemniscate shape (∞), with a flat bottom edge and is planned for charging battery electric vehicles at up to 900 kilowatts using direct current. The design incorporates backward compatibility with CHAdeMO and the GB/T DC-charging, using a dedicated inlet adapter for each system. The circuit interface of ChaoJi is also designed to be fully compatible with the Combined Charging System, also known as CCS.
