NINGDE, China, Dec. 24,
2024 /PRNewswire/ -- On December 24th, CATL
officially launched the CATL Bedrock Chassis, the world's first
ultra-safe skateboard chassis. With its outstanding performance of
withstanding 120 km/h frontal impact without catching fire or
exploding, CATL's Bedrock Chassis sets a new standard for
intelligent chassis safety, providing comprehensive protection
across all scenarios and speed ranges.
Lead the industry with the most stringent safety
tests
With the battery-centered design, CATL's Bedrock Chassis
utilizes Cell-to-Chassis integration technology, which directly
integrates the battery cells into the chassis, allowing for a
shared structural design between them. And based on the decoupling
of the chassis from the upper body, the Bedrock Chassis is capable
of absorbing 85% of the vehicle's collision energy (compared to
around 60% absorbed by traditional chassis).
Through various technological breakthroughs, the Bedrock Chassis
successfully passed the world's first "highest speed + strongest
impact" dual extreme safety test. This achievement enables the
chassis to pass the 120 km/h frontal central pole impact test
without catching fire, exploding or thermal runway, redefining the
benchmark for safety in the industry.
Currently, the speed for frontal impact safety test in the
commonly used C-NCAP (China New Car Assessment Program) is 56km/h,
which, when experiencing a frontal impact at this speed, generates
collision energy equivalent to falling from 12-meter-high building.
In comparison, a frontal impact at 120km/h is equivalent to falling
from a 56-meter-high building, generating a collision energy 4.6
times that of collision at 56km/h.
In more stringent frontal pole crash tests, which simulate
crashes with non-standard objects such as power poles, large trees,
or animals, the impact area is only 1/6 of that in a full-width
frontal impact, exponentially increasing impact pressure. At a
speed of 120km/h, the impact pressure on the chassis per unit area
in a frontal central pole impact is 21 times that of the 56 km/h
full-width frontal impact in C-NCAP testing.
Due to the extremely high crash speed and intensity, there has
been no previous instance of any new energy vehicle daring to
challenge a 120km/h frontal pole impact test. With this extreme
challenge, CATL's Bedrock Chassis has blazed a fresh trail for
the industry.
Open the era of ultra-safe transportation through three
technological breakthroughs
CATL's Bedrock Chassis has delved deep into the realm of
structure and material innovation, leveraging three technological
breakthroughs to provide unparalleled protection in all scenarios
and speed ranges, ensuring rock-solid safety for the entire
vehicle.
The CATL Bedrock Chassis introduces a revolutionary
three-dimensional biomimetic tortoise shell structure, where the
body and energy unit framework are integrated, deeply coupled to
provide the energy unit with indestructible protection. And its
aircraft carrier-grade arresting structure disperses impact forces
across multiple pathways during a crash, gradually decelerating the
vehicle and significantly reducing the depth and speed at which
obstacles intrude the cabin. The utilization of submarine-grade
hot-formed steel with a strength of 2000MPa, aerospace-grade
aluminum alloy with a strength of 600MPa, and multiple barrier
structures further enhance the chassis' rigidity, making it
virtually impervious.
Moreover, the CATL Bedrock Chassis incorporates an ultra-safe
battery cell design, NP technology, and a high-ductility
energy-absorbing insulation film, leading the industry in a
groundbreaking manner. In terms of high-voltage disconnection, it
achieves instantaneous disconnection of high voltage circuit within
0.01 seconds of impact and completes the discharge of residual
high-voltage energy in the vehicle within 0.2 seconds, setting a
new industry record.
Notably, the battery cells have undergone highly demanding
tests, including high-speed sled impact tests at 60 km/h, 90-degree
bending tests, and breakthrough sawing tests, the battery did not
catch fire or explode across all three tests. These tests, all
industry-firsts by CATL, have elevated the safety standards of
battery cells to new heights.
Unlocking the era of customization, and activating a
trillion-yuan market
The launch of the Bedrock Chassis not only redefines the
standard for intelligent chassis safety but also activates a
trillion-yuan market. It greatly accelerates the shift towards
modular, personalized, and intelligent automotive design.
Addressing the common pain points of high investment, long
development cycles, and accelerated product iteration in the
industry, the Bedrock Chassis incorporates three core
characteristics: internal integration, decoupling of the chassis
from the upper body, and external openness. With a rich array of
toolkits and solution packages, it offers a scalable software and
hardware architecture and standardized interfaces, enabling
flexible configurations for different vehicle models and scenarios.
This allows the realization of a "one chassis architecture,
multiple vehicle models" concept and significantly improves
development efficiency and shortens the R&D cycle. The time
required for mass production of a vehicle is reduced from the
traditional 36 months or longer to 12 to 18 months.
Furthermore, the Bedrock Chassis breaks the limits of safety and
modeling, and expands design flexibility through the design of
decoupling of the chassis from the upper body. The
fourth-generation Cell-to-Chassis (CTC) technology and inverted
battery cell technology enhance the utilization of chassis space
while reducing the risk of chassis scraping. Additionally, in terms
of intelligence, the chassis supports mechanical decoupling,
software decoupling and EE decoupling, enabling L3 to L4
intelligent driving capabilities. It provides high adaptability
interfaces and promotes collaborative intelligent applications.
At the launch ceremony, AVATR, the first automaker to use
Bedrock Chassis, and CAIT-SH, CATL's skateboard chassis arm, signed
an agreement to deepen cooperation on CATL's Bedrock Chassis to
create a safer, higher-quality travel experience for users.
Safety is a never-ending journey. In the future, CATL will
continue to break technological barriers through continuous
innovation, and work with partners to build a safe ecosystem for EV
batteries and vehicles, safeguarding the safety of users.
