Pure tram because the bottom is covered with batteries, so in the body structure need to be considered, zero run recently released a technology called CTC, some similar to the integrated battery design of smart phones, what is going on?
Zero-run cars' own interpretation of CTC technology is to integrate the design of batteries, chassis and car bodies to simplify product design and production processes. By redesigning the battery bearing tray, the entire chassis structure of the car body is coupled with the battery tray structure, reducing the redundant structural design, which can effectively reduce the number of parts, improve the space utilization rate 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. CTC technology uses the body structure as the external structure of the battery pack, eliminating 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, with the potential for continuous evolution, becoming a "sustainable evolutionary energy matrix".
In terms of space, by canceling the battery superstructure and reducing the 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 battery life, 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 energy economy management brought by the innovative software application AIBMS big data battery management system, comprehensively improve the vehicle mileage by 10%.
In terms of performance, CTC technology can bring a 25% increase in torsional stiffness and a 2.4% reduction in weight factor, an increase of 20%. The higher the torsional stiffness of the body, the stronger the resistance to resonance, which can also contribute to NVH performance. According to the official statement, CTC technology has carried out several rounds of rigorous tests, such as bottom ball hitting, extrusion, thermal diffusion and nearly 30 tests to ensure battery safety, of which 8 safety test results far exceed national standards; at the same time, based on the zero-run AI BMS big data intelligent battery management system, zero-run can provide users with real-time cloud security protection at the touch cell level, and have been comprehensively improved in battery safety, battery life, and battery performance.
