On April 25, Zero Run released the intelligent power CTC technology, which applies the body structure as the external structure of the battery pack, and cancels part of the structural design of the battery pack. Based on battery performance, space-arrangable gains and innovations in software applications, this technology comprehensively increases the vehicle's cruising range by 10% and will be the first mass-produced application on the Zero-Run C01. Zero-run cars said that with the evolution of technology, the future can be charged for 5 minutes and have a range of more than 200km.
Inspired by the integrated battery design of smart phones, the battery R&D team of Zero Run has been developing integrated battery and chassis integration technology since 2016. Song Yining, general manager of the battery product line of Zero Run Technology, introduced: "Zero Run Intelligent Power CTC Technology, that is, cell-to-chassis, refers to the cutting-edge technology of integrating 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. Reducing redundant structural design can effectively reduce the number of parts, improve space utilization and system specific energy at the same time, so that the body and battery structure complement each other, so that the battery impact resistance and body torsional stiffness have been greatly improved.
The dual innovation of software and hardware realized by this technology can fully empower the product. 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, with the potential for continuous evolution, becoming a "sustainable evolutionary energy matrix".
In terms of space, the vertical space of the vehicle is increased by 10mm, and the battery layout space is increased by 14.5%, which makes the space layout in the car more flexible and practical. In terms of endurance, this technology has better airtightness than traditional solutions, which can improve battery insulation performance, battery space, etc., and at the same time, based on the energy economy management brought by the innovative software application AI BMS big data battery management system, comprehensively improve the vehicle mileage by 10%. In terms of performance, the technology can increase the torsional stiffness of the whole vehicle by 25%, and the lightweight factor can reach 2.4, an increase of 20%.
It is reported that in the development process of zero run, for the intelligent power CTC technology, several rounds of rigorous tests have been carried out, such as bottom ball hitting, squeezing, thermal diffusion and nearly 30 tests to ensure battery safety.
