Recently, Wu Kai, chief scientist of CATL, was invited to attend the 2023 International Automotive Electronics and Software Conference - Dishui Lake Summit hosted by the China Society of Automotive Engineers. During the event, he delivered a keynote speech titled “CTC-focused Skateboard Chassis Design.”

Abstract

As consumer demands for electrification and intelligence continue to grow, the traditional integration of the chassis with the body has started to evolve. The skateboard chassis offers more efficient integration, greater adaptability, and rapid iteration capabilities, allowing for swift responses to consumer needs. Here are the key points shared by Dr. Wu Kai with the industry from this event.

Features of Integrated Intelligent Skateboard Chassis

The vehicle body is separated into upper and lower parts, allowing for independent motion and control of the chassis.

Different interfaces are decoupled while functional modules are combined, reorganized, and redistributed.

The upper body serves as the vehicle's 'brain' and intelligent space, while the lower chassis acts as the 'cerebellum', the carrier of energy and motion units.

CATL's CTC-focused Integrated Intelligent Chassis Design

Leveraging Cell To Chassis (CTC) technology maximizes the battery layout space within the chassis.

The high integration of the e-Drive, thermal management, and suspension systems cuts down weight and cost while maximizing the efficiency of the battery, e-Drive, and thermal management systems.

The Smart Integrated Chassis Controller (SICC) effectively manages energy and motion.

Four Major Innovations of CATL's CTC Energy Unit Technology

Integration of battery into chassis - enhancing energy efficiency

All-in-one and SICC technology - optimizing energy intelligence

Multi-source heat pump technology - improving energy stability

Multi-level active and passive security protection technology - enhancing energy security

The Significance of Skateboard Chassis to the Industry

The skateboard chassis promotes the development of an industrial ecosystem through standardization. With six major standardized interfaces including mechanical, electrical, software, communication, data, and service interfaces, the skateboard chassis is poised to become the cornerstone of the future industrial ecosystem.

Model Innovation with the Skateboard Chassis Product Form

The skateboard chassis enables an industry “sharing” model. Leveraging higher volume group efficiency for cost advantages, it assists partners in cost reduction and efficiency improvement while significantly shortening the launch cycle of new vehicles.

“We hope to work closely with all partners to shape the future of intelligent travel through Integrated Intelligent Chassis”, said Dr. Wu Kai.
