From September 27 to 29, 2024, the World New Energy Vehicles Congress (WNEVC) 2024 was held in Haikou, Hainan. As an influential international conference in the auto industry, the WNEVC 2024 aimed to promote innovation and cooperation in the global new energy vehicle market.

At the New Energy Vehicle Platform and Key Technology Innovation Forum, Dr. Wu Kai, Chief Scientist of CATL, announced the official release of the Concept, Design Principles and Standardization Initiative of Integrated Intelligent Chassis (Standardization Initiative). This document was edited by CATL (Shanghai) Intelligent Technology under the guidance of the China Society of Automotive Engineers.

CIIC (i.e. skateboard chassis) demonstrates a novel concept for auto design. The core features of “decoupling of the upper body and the chassis and parallel development” make “shared chassis” possible. With the maturation of electrification and AI applications, auto hardware and basic technologies are becoming more homogenized. CIIC will give a considerable boost to the efficiency of the auto industry, streamline the vehicle development cycle, and open up unlimited possibilities for scenario-based vehicle manufacturing and upper body design that allows for a higher level of freedom.

Zhang Junzhi said that electrification and AI applications are two factors propelling rapid chassis development and transformation. The recent years has seen the rapid development of the intelligent chassis. The integrated design and control of the power system (e.g., motors and batteries) and the chassis, in particular, has given a new boost to the transformation and development of chassis technologies.

(Zhao Lijin, Deputy Secretary-general of the China Society of Automotive Engineers)

Zhao Lijin said that vehicles have transformed from merely a means of transportation to an intelligent terminal for mobile travel, and that the demand for multi-scenario and versatile auto product forms poses new challenges to the chassis architecture. As a crucial path for chassis development in the future, CIIC deserves industry-wide attention and concerted efforts to explore standard formulation and the industrial ecosystem.

Dai Dali said that CIIC has brought massive changes to the model for vehicle development. As the industry’s first vehicle developed based on CIIC, the CIIC 800V model of Neta S Shooting Brake has been put into mass production and will soon be delivered. The CIIC also charts a new path for the manufacturing and R & D of smart cars.

Based on technologies and practices related to the CIIC, CATL (Shanghai) Intelligent Technology has proposed a highly intelligent skateboard chassis design concept which focuses on batteries. Through scalable architecture and standardized interfaces, it can adapt to a versatile range of vehicle models.

With the rapid development of the new energy vehicle industry, there is a surge of demand for integrated intelligent chassis. Under the “shared chassis” model, there are urgent requirements for standardized interfaces and fully developed application ecosystems to overcome barriers, achieve common technology development and system compatibility despite the needs for different models, promote the healthy development of the auto industry, achieve sharing of resources and strengths, and provide users with a safer, smarter and more personalized travel experience.

The Concept, Design Principles and Standardization Initiative of Integrated Intelligent Chassis (Standardization Initiative) at the conference is the first attempt of the auto industry to elaborate on the concept and basic attributes of the skateboard chassis, and call on all partners in the new energy vehicle industry to formulate standards with concerted efforts.

In July 2024, the C-SAE standard Intelligent Skateboard Chassis: Mechanical Performance Requirements and Test Methods for Bolted Interface was reviewed and approved. The formulation of this standard was led by CATL (Shanghai) Intelligent Technology and promoted by the China Industry Technology Innovation Strategic Alliance for Electric Vehicle. “We welcome partners to join us in the formulation of technical standards for integrated intelligent chassis. We also anticipate to work with global partners to create a bright future for new energy vehicles and travel!” said Cai Jianyong, CTO of CATL (Shanghai) Intelligent Technology.
