Shulou(Shulou.com)12/24 Report--

Thanks to CTOnews.com netizens for the delivery of clues about the past. CTOnews.com November 28 news, today, Xiaomi Automotive Technology Co., Ltd. applied for the "battery and body integrated structure, vehicle" patent announced.

It is shown that the integrated structure of the battery and the car body includes a car body and a power battery pack, and the car body includes two threshold beams, which are arranged at intervals along the left and right directions of the vehicle, and each threshold beam is provided with a battery package installation part. Through the above technical scheme, the top of the battery cladding shell is integrated with a crossbeam, which can strengthen the shell main body and improve the stiffness and side impact force transfer performance of the battery cladding shell, and the top of the battery cladding shell serves as the floor panel. it is beneficial to improve the integration degree of the vehicle, reduce the self-weight of the body structure, realize the lightweight of the vehicle, and improve the mileage of the vehicle.

According to CTOnews.com, with the upgrading and iteration of power battery technology and new energy vehicle manufacturing technology, car companies have gradually shifted from CTP (battery large module or non-module technology) to CTC / CTB (battery chassis / body integration technology). As a new generation of battery system technology, CTC realizes the integrated design of battery, chassis and lower body, simplifies product design and production process, improves vehicle stiffness and space, and increases battery capacity and driving range while reducing cost. Compared with CTP moduleless technology, CTC simplifies the production process by combining the floor panel and the battery pack cover into one, reducing the gap and connecting parts between them, and the battery core is not only a source of kinetic energy for the whole vehicle, but also a structural part to increase the rigidity of the chassis / body.
