ChaoJi
The ChaoJi connector, also referenced as CHAdeMO 3.0, is an ultra-high-power charging standard charging 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 (used globally) and the GB/T DC-charging (used mainly in mainland China), 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 (used mainly in Europe and North America).

A joint agreement between the CHAdeMO association and the China Electricity Council (with State Grid Corporation of China) was signed on 28 August 2018 after which the development was enlarged to a larger international community of experts.
