Introduction to CATL's Bedrock Chassis
CATL has officially launched the Bedrock Chassis, which has made waves as the world's first ultra-safe skateboard chassis. This innovative design is capable of enduring a frontal impact at speeds of up to 120 km/h without igniting or exploding. The introduction of this chassis sets a new benchmark for safety in the automotive industry, ensuring comprehensive protection in various scenarios.
Leading the Charge in Safety Testing
With a commitment to exceeding safety standards, CATL has developed this chassis through rigorous testing. The Bedrock Chassis has been subjected to the most stringent safety tests designed to simulate extreme conditions. This included the "highest speed + strongest impact" dual extreme safety test, demonstrating its resilience by surviving a frontal impact test at 120 km/h without any thermal runaway, fire, or explosion.
Collision Energy and Impact Tests
In conventional tests like the C-NCAP (China New Car Assessment Program), the frontal impact safety speed is capped at 56 km/h. A collision at this speed is equivalent to falling from a 12-meter-high building. In contrast, the Bedrock Chassis, enduring impacts at 120 km/h, reaches an energy equivalent to falling from a staggering 56 meters. This increased intensity translates to a collision energy 4.6 times greater than that of the C-NCAP standards.
The Challenges of High-Speed Testing
The complexity of crash tests at such high speeds involves various factors. For example, the pressure experienced per unit area in non-standard impact tests, simulating hits with objects like trees or poles, can reach alarming levels. The impact pressure at 120 km/h is approximately 21 times that experienced at 56 km/h, showcasing the chassis's capability to manage and diffuse incredible forces.
Innovative Design Features of the Bedrock Chassis
One of the notable features of CATL's Bedrock Chassis is the innovative structure that combines the body and energy units, effectively employing a three-dimensional biomimetic design inspired by natural systems. This structure not only protects the energy unit but enhances the overall structural integrity of the vehicle. The chassis includes aircraft carrier-grade arresting structures that help distribute impact forces more effectively during a crash.
Material Technologies for Enhanced Rigidity
The design also employs advanced materials such as submarine-grade hot-formed steel and aerospace-grade aluminum, which enhances the overall rigidity and durability of the chassis, ensuring that it can withstand significant forces during collisions. This commitment to materials science positions the Bedrock Chassis as a leader in automotive safety technology.
Advanced Safety Features in Battery Design
Safety is also paramount in the battery design of the Bedrock Chassis. The inclusion of NP technology and a specialized energy-absorbing film allows for immediate disconnection of high-voltage circuits upon impact. Remarkably, it can discharge residual high-voltage energy quickly, representing a significant advancement in battery safety protocols.
Redefining Market Standards and Customization
The introduction of the Bedrock Chassis heralds a new era of automotive design, activating a significant market potential worth trillions. The design allows for rapid customization and modular applications, addressing long-standing challenges such as extensive development cycles and high costs in vehicle production.
Improving Efficiency in Vehicle Production
By incorporating internal integration and external openness, the chassis enhances flexibility in overall design. It drastically reduces the time for mass production—from 36 months to a mere 12 to 18 months—effectively streamlining vehicle development processes and accelerating the introduction of innovative vehicle models.
Supporting Advanced Driving Technologies
Intelligent features also play a role in the Bedrock Chassis, accommodating various intelligent driving technologies while providing adaptability for different models. This innovative approach promotes not only safety but also enhanced user experiences within the vehicle.
Collaboration with Automakers
At the launch, CATL showcased its commitment to collaboration with industry partners. AVATR, the first automaker to implement the Bedrock Chassis, has entered into a partnership with CATL to further enhance the safety and quality of transportation for consumers.
As CATL continues to innovate and push automotive safety standards higher, its goal remains consistent: to create a safer ecosystem for EV batteries and vehicles, ensuring user safety well into the future.
