CHAOJI Charging Connector

On September 7, 2023, the State Administration for Market Regulation of China issued the 9th National Standard Announcement of 2023, approving a series of new standards related to electric vehicle charging. These standards are all associated with ChaoJi charging technology.

ChaoJi standards exhibit noticeable differences from the currently used GB/T 2015 standards, especially in terms of the charging plug's external appearance. With an electric vehicle inventory exceeding 17 million and a public charging station inventory of 2.27 million units, both utilizing the GB/T 2015 standard, the challenge of promoting an entirely different standard for the plug is undeniably significant.

ChaoJi charging technology originates from the high-power charging demands of electric vehicles, encompassing a comprehensive conductive charging system solution, including charging connection components, control and guidance circuits, communication protocols, charging system safety, and thermal management. It meets the requirements for fast, safe, and compatible electric vehicle charging.

Compared to existing standards, the ChaoJi charging standard has made significant improvements and enhancements in mechanical safety, electrical safety, electric shock protection, fire safety, and thermal safety design.

The most noticeable improvements include higher charging power and a smaller charging interface size.

The ChaoJi charging standard can support higher charging power, as its cable assembly adopts a liquid cooling method and incorporates a temperature monitoring system. Its maximum charging power can reach 900 kW. This means that the new standard can achieve faster charging speeds.
