On April 25, ZeroCar officially released the CTC battery chassis integration technology, which can improve the vehicle's endurance by about 10%, and the C01 model will be the first to be installed. In addition, Zero Run also announced that it will be free and open to CTC technology.
Inspired by the integrated battery design of smart phones, the battery research and development team began to develop integrated battery and chassis integration technology in 2016. Zero-run intelligent power CTC technology, or cell-to-chassis, refers to the cutting-edge technology that integrates the design of batteries, chassis and car bodies to simplify product design and production processes. The installation process was innovated by redesigning the battery carrier tray so that the entire chassis structure of the car body was coupled with the battery tray structure. By reducing the redundant structural design, the number of parts can be reduced, and while improving the space utilization rate and system specific energy, the body and the battery structure complement each other, so that the battery impact resistance and body torsional stiffness are greatly improved.
It is worth mentioning that the zero-run intelligent power CTC technology applies the body structure as the external structure of the battery pack, and cancels part of the structural design of the battery pack. At the same time, it also has high adaptation and strong expansion attributes, which can achieve rapid and flexible production, and is more compatible with higher voltage platforms and models of various levels and types in the future.
In terms of space, zero-run intelligent power CTC technology innovates in hardware and structural design, and by eliminating the battery superstructure and reducing redundant structural design, the vertical space of the vehicle is increased by 10mm, and the battery layout space is increased by 14.5%, making the space layout in the car more flexible and practical.
In terms of endurance, zero-run intelligent power CTC technology has better airtightness than traditional solutions, which can improve battery insulation performance, battery space, etc., and at the same time, based on the innovative software application AI BMS big data battery management system to bring energy economy management, comprehensively improve the vehicle mileage by 10%.
In terms of performance, zero-run intelligent power CTC technology can bring 25% increase in torsional stiffness and 2.4% reduction factor to the vehicle, an increase of 20%. The higher the torsional stiffness of the body, the stronger the resistance to resonance, which means that the vehicle can have better driving control performance and chassis response efficiency, which can also contribute to NVH performance.
In terms of safety, Zero Run conducted several rounds of rigorous tests for intelligent power CTC technology during the development process, such as bottom ball hitting, extrusion, thermal diffusion, etc., to ensure battery safety, of which 8 safety test results exceeded national standards.
