“ChaoJi”: Revolutionizing the Charging System




Did you know that "ChaoJi" was born in China a few days ago?

This innovation has the potential to reshape the world of charging systems.


Recently, the State Administration for Market Regulation of China (National Standardization Management Committee) announced the approval of a series of new national standards for electric vehicle (EV) charging. These standards, collectively known as "ChaoJi," were jointly developed by China, Japan, Germany, and other countries. Let's explore some key features of the ChaoJi charging system:



  • Enhanced Compatibility: The ChaoJi charging system addresses the issue of forward compatibility, ensuring seamless integration with existing charging infrastructure. It offers solutions compatible with four major charging systems: GB/T2015, CHAdeMO, CCS1, and CCS2. By utilizing a redesigned guiding circuit and adapters, vehicles equipped with ChaoJi interfaces can charge using existing diverse interfaces without requiring any software or hardware modifications. New-generation ChaoJi charging equipment can accommodate legacy vehicles through dual or multiple ports, eliminating the need for retrofits.


  • Improved Charging Safety: The ChaoJi charging system incorporates significant improvements in mechanical safety, electrical safety, protection against electric shock, fire prevention, and thermal safety. Experts from various countries, including members of IEC TC69 and SC23H, participated in the ChaoJi working group. The project aligns with the latest IEC standards' safety models while considering specific market requirements.


  • Enhanced Charging Power: The ChaoJi charging system employs liquid cooling for its cable components and incorporates a temperature monitoring system. This design allows for a maximum charging power of up to 900 kW, meeting the demand for high-power charging and significantly reducing charging time, akin to refueling at a gas station.


  • Innovative Design: Compared to international standards such as GB/T2015, CHAdeMO, CCS1, and CCS2, the ChaoJi charging interface boasts the smallest size. It also considers the combination of DC and AC interfaces, facilitating vehicle manufacturers' design choices. Targeting safety concerns and design flaws in existing systems, ChaoJi provides a compact design that prioritizes performance and reliability.


  • Future-Ready Applications: With the increasing adoption of electric vehicles, the charging market continuously evolves, demanding interfaces that support new functionalities and operating models. The ChaoJi charging system accommodates emerging technologies such as plug-and-charge, vehicle-to-everything (V2X), and automated charging systems. It supports future communication interface upgrades from CAN to Ethernet, leaving room for upgrades to ultra-high-power charging (above 1,000 A) and considering future technological advancements. ChaoJi offers a well-designed interface system with flexibility and scalability.

The ChaoJi technology addresses a range of deficiencies and issues present in existing international charging systems. It caters to high, medium, and low-power charging, considers charging and discharging requirements, and meets the needs of residential and various public charging scenarios. By fundamentally resolving the inherent flaws in China's existing 2015 standards, such as inadequate electric shock protection (IPXXB) and incompatibility with future communication upgrades, ChaoJi provides a unified, safe, reliable, and cost-effective charging system solution for the world.


The birth of ChaoJi marks a significant milestone in the evolution of charging systems, with the potential to revolutionize the electric
