Contemporary Amperex Intelligence Technology (Shanghai) Limited (CAIT-SH) is leading the development of a new CSAE standard facilitated by the China Industry Technology Innovation Strategic Alliance for Electric Vehicle. Titled “Intelligent Skateboard Chassis -- Mechanical Performance Requirements and Test Methods for Bolted Connection Interface,” the standard has successfully passed the project review and has been incorporated into the development plan of the China Society of Automotive Engineers (CSAE).

The standard is intended to standardize the design and manufacturing of skateboard chassis with rigid bolted connections between the upper and lower bodies. It mainly addresses technical areas such as body connection interfaces and sealing interfaces.

The CSAE is soliciting drafting organizations and welcomes interested parties to jointly promote the implementation of this standard. To join the standard drafting working group, please add the contact person from the Standards Management Department on WeChat and register on the CSAE Standard Information Platform at http://csae.sae-china.org/.

The standard titled “Intelligent Skateboard Chassis -- Mechanical Performance Requirements and Test Methods for Bolted Connection Interface” is being developed with Contemporary Amperex Intelligence Technology (Shanghai) Limited (CAIT-SH) as the leading drafter and facilitated by the China Industry Technology Innovation Strategic Alliance for Electric Vehicle. The standard has successfully passed the project review and has been incorporated into the development plan of the China Society of Automotive Engineers (CSAE) with the Drafting Work Program numbered 2024-019. The CSAE is soliciting drafting organizations and welcomes interested parties to jointly promote the implementation of this standard.

The intelligent skateboard chassis is an innovative technology key to decoupling the upper and lower bodies of vehicles and enabling parallel development and asynchronous iteration. It provides strong support for the personalized and scenario-based development of intelligent electric vehicles . As Premier Li Qiang emphasized at the State Council meeting in June 2023, strengthening the research and development of key technologies such as power battery systems, new chassis architectures, and intelligent driving systems is crucial for enhancing the independent and controllable capabilities and green development of the entire industry chain.

Currently, the development of intelligent electric vehicle chassis faces numerous challenges, including lengthy development cycles, high risks, and uncontrollable costs. Traditional in-house interfaces and closed architectures lead to redundant development and validation of parts, especially for low-volume models, resulting in high future maintenance costs. The new CSAE standard aims to simplify the connection and matching of chassis modules through standardized interfaces, thereby accelerating market response and reducing production costs.

The standard specifically addresses skateboard chassis with rigid bolted connections between the upper and lower bodies, focusing on the design and manufacturing specifications for body connection interfaces and sealing interfaces. It will give detailed strength and stiffness requirements of connection points, encompassing safety in the case of collision, ultimate strength conditions, durability conditions, torque decay, and corresponding test methods. It will also clarify the waterproof, anti-aging, weather resistance, water management, and anti-corrosion requirements of sealing interfaces while providing recommendations on standardizing key components such as air conditioning pipelines and high- and low-voltage connectors.

The standardization task is expected to enhance the safety and reliability of intelligent electric vehicles and drive the entire industry's healthy development, providing a solid technical foundation for the future of intelligent mobility. CATL, with its forward-looking technological innovation capabilities, takes the lead in the standardization of intelligent EV chassis technology.
