CATL's lithium iron phosphate battery skateboard chassis is expected to be mass-produced in the second half of the year, leading the innovation trend of new energy vehicles

At the 2024 China Electric Vehicle Hundreds Conference, CATL (Shanghai) Intelligent Technology Co., Ltd. announced that their first lithium iron phosphate battery skateboard chassis product plans to start mass production in the second half of this year. In November last year, the company launched a skateboard chassis product using ternary lithium batteries with a cruising range of more than 1,000 kilometers, and successfully completed testing in Heihe winter and Turpan summer.

Skateboard chassis, this innovative design in the field of new energy vehicles, takes batteries, motors, and electronic controls (three electrics) as the core. Compared with traditional car chassis designs, Greatly reduces the need for distributed electronic control units. According to the editor's understanding, Yang Hanbing, the managing director of CATL (Shanghai) Intelligent Technology Co., Ltd., expressed optimism about the development prospects of skateboard chassis in the field of new energy passenger vehicles. He believes that the skateboard chassis not only changes the basic attributes of the car, but also improves the user experience and conforms to the development trend of intelligence.

Since 2018, CATL has been committed to the research and development of skateboard chassis technology. This technology is based on CTC technology and pursues high efficiency, lightweight, low cost and safety. This design realizes multi-faceted decoupling of the car body, making the car a carrier that can drive independently, while also improving resource utilization efficiency and intelligent experience. Yang Hanbing emphasized that CATL’s skateboard chassis has the advantages of rapid market launch, low cost and high degree of design freedom. For example, it can help automakers launch new models within 18 months, significantly shortening the traditional 36 to 48-month development cycle. In addition, the skateboard chassis can also reduce vehicle development costs and BOM costs, bringing cost advantages to partners.

In terms of safety, CATL’s skateboard chassis can absorb up to 85% of collision energy, reducing the impact of styling on vehicle safety. At the same time, it also provides open E interfaces and mechanical interfaces, providing automotive designers and product managers with greater design freedom. In addition, the skateboard chassis also performs well in terms of power consumption and fast charging. Its power consumption per 100 kilometers is only 11 kWh, which is much lower than other cars; and the fast charging technology can charge the battery SOC from 30% to 80% in 10 minutes, thanks to the 800V electric drive system developed by the company. The overall efficiency of the system is as high as 91.7%.

Currently, CATL has cooperated with a number of car companies, including Nezha Automobile, Vietnam's Vinfast, etc., and has signed strategic cooperation framework agreements with Alt and Gecko Technology to jointly promote the industry in the field of skateboard chassis. ecological development. Yang Hanbing said that CATL is actively promoting the standardization of skateboard chassis and looks forward to participating in this process with partners upstream and downstream in the industry.

The above is the detailed content of CATL's lithium iron phosphate battery skateboard chassis is expected to be mass-produced in the second half of the year, leading the innovation trend of new energy vehicles. For more information, please follow other related articles on the PHP Chinese website!
