Wu Kai reveals: Ningde era skateboard chassis achieves a cruising range of over 1,000 kilometers

November 16 news, recently at the 2023 International Automotive Electronics and Software Conference Dishui Lake Summit, Wu Kai, chief scientist of CATL, announced a major technological breakthrough. He said that Times Intelligence, a subsidiary of CATL, has successfully developed a new type of skateboard chassis. This technology has been applied on B-class cars in cooperation with CATL and has been fully tested under extreme climate conditions

Wu Kai introduced the skateboard in detail Various technical features of the chassis. This chassis enables battery assembly efficiency to reach 75%, pushing the cruising range to exceed the 1,000-kilometer mark. Under extreme low temperature conditions, battery performance degradation is controlled to less than 30%, and it remains stable even in an environment of minus 7 degrees. In addition, this model has also achieved significant optimization in power consumption per 100 kilometers, requiring only 10.5kWh. The most eye-catching thing is that this model supports fast charging and can charge for 300 kilometers in just 5 minutes, which greatly improves the convenience of use. In terms of safety, the chassis meets the CNCAP five-star crash test standard and can absorb more than 80% of collision energy to ensure passenger safety.

The editor learned that Wu Kai emphasized the advanced integrated design of this skateboard chassis. The chassis integrates high and low voltage systems, as well as steering and braking systems, and is equipped with a dedicated chassis domain controller. This highly integrated design not only optimizes vehicle performance, but also heralds the technology’s near future, that is, the third quarter of 2024, which is expected to achieve mass production

Introducing the design concept of the skateboard chassis, CATL Representatives of the company pointed out that the so-called skateboard chassis is a design that integrates key components such as batteries, electric drive systems, suspensions, and brakes into the chassis in advance. This design can not only reduce the purchase cost and operating energy consumption of the vehicle, but also effectively expand the vehicle's internal space. In addition, this chassis design also has high flexibility. Through the reserved electrical and car body interfaces, the upper and lower car bodies can be separated and decoupled, so that the upper car body can be replaced according to actual needs, so that a set of chassis A number of different types of models can be developed. Because of its high degree of integration, flat surface, and shape similar to a skateboard, it is named "skateboard chassis". This design concept heralds an innovative trend in the field of future automobile design and manufacturing
