[3] 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),[4] 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).

[7] The new EVs implementing the standard are to be fitted with a female ChaoJi DC inlet, with a vehicle-side locking mechanism.

[10] A new coupler codenamed  'Ultra-ChaoJi' with an additional set of power pins above the standard ChaoJi pinouts, is currently under development.
