Jiwei network news (text / Chen Wei) On April 25, the zero-running car CTC (Cell-To-Chassis) battery technology was officially released, CTC refers to the integrated design of the battery and chassis, which is the cutting-edge technology to improve the performance of the vehicle, the technology redesigned the battery bearing tray, so that the entire chassis structure of the car body is coupled with the battery tray structure, and the installation process is innovated.
It is reported that this technology can effectively reduce the number of parts by reducing the redundant structural design; 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 have been greatly improved.
CTC battery chassis integration structure has two highlights: one is to improve structural efficiency, battery and chassis integration design, battery skeleton structure and chassis body structure into one, so that both the chassis body structure and battery structure, structural efficiency is higher; the second is to solve the problem of airtightness, through the body design to achieve battery sealing, CTC technology borrows the basic structure of the chassis, the use of body longitudinal beams, beams to form a complete sealing structure, compared to the traditional car This is a major innovation.
It is worth mentioning that CTC technology increases the battery layout space by 14.5%, the vertical space of the body increases by 10mm, the vehicle comprehensive endurance increases by 10%, the utilization rate of battery space is higher, and the winter thermal insulation performance is more; the torsional stiffness of the body is increased by 25%, the chassis response is faster, the body lightweight coefficient is increased by 20% compared with the traditional solution, the same level coefficient is better, and the economic performance is more balanced; the structural complementary safety is greatly improved, 30+ tests ensure reliable safety, and AI BMS provides full-time active protection.
In addition, CTC technology and the vehicle matching degree is high, can be quickly flexible mass production, can be cross-platform adaptation to future levels, types of models; at the same time, integrated thermal management system, the future can be compatible with 800V high-voltage platform, support 400kW super fast charging, the future can achieve "refueling" charging, that is, charging 5 minutes, endurance 200 + km.
Zero-run car said that CTC battery chassis integration technology brings more core advantages, to achieve the perfect combination of space, performance, endurance, safety, CTC technology represents the latest achievements of zero-running car 7 years of global self-research routes. In addition, the zero-run intelligent power CTC battery chassis integration technology will help the world's first mass-produced car equipped with CTC technology - zero-run C01.
