Today, the patent for “integrated battery and body structure, vehicle” applied by Xiaomi Automobile Technology Co., Ltd. was published.
The abstract shows that the integrated structure of the battery and the body includes the body and the power battery pack. The body includes two threshold beams, and two threshold beams are spaced along the left and right directions of the vehicle, with a battery pack installation section on each threshold beam. With the above technical solution, the top of the battery pack shell is integrated with cross beams, which can strengthen the main body of the shell, improve the rigidity and side impact transmission performance of the battery pack shell, and the top of the main body serves as the floor panel, which is conducive to improving the integration level of the vehicle, reducing the self-weight of the body structure, achieving vehicle lightweight, and increasing the vehicle’s range. Rewritten in TSN style: The integrated structure of the battery and the body features two threshold beams along the left and right directions of the vehicle, each with a battery pack installation section. The top of the battery pack shell is integrated with cross beams to strengthen the shell and improve rigidity and side impact transmission performance. This design also serves to reduce the vehicle’s self-weight and achieve lightweight construction, ultimately increasing the vehicle’s range.
According to IT Home, with the upgrade and iteration of power battery technology and new energy vehicle manufacturing technology, car companies have gradually shifted from CTP to CTC / CTB in the selection of power battery installation. As a new generation of battery system technology, CTC integrates the design of battery, chassis, and lower body, simplifying product design and production processes, improving vehicle rigidity and space, while reducing costs and increasing battery capacity and driving range. Compared with CTP’s module-free technology, CTC mainly combines the floor panel and battery pack cover, reducing the gaps and required parts between the two, simplifying the production steps. The battery core is both a source of energy for the entire vehicle and a structural component that increases chassis/body rigidity.
