CATL unveils Bedrock skateboard chassis with focus on safety - CnEVPosthttps://cnevpost.com/2024/12/24/catl-unveils-bedrock-skateboard-chassis/CATL presented a video at today's event showing a prototype built on the Bedrock Chassis that did not catch fire, explode, or suffer thermal runaway in a 120 km/h frontal central pole impact test.
The crash energy in the test is equivalent to 4.6 times the energy produced in the commonly used C-NCAP frontal crash safety test at 56 km/h.
The Bedrock Chassis utilizes a three-dimensional bionic tortoise shell structure with the body integrated into the energy unit frame to provide protection for the energy unit.
It uses submarine-grade hot-formed steel with a strength of 2,000 MPa, aerospace-grade aluminum alloys with a strength of 600 MPa, and multiple barrier structures to further enhance chassis rigidity, according to CATL.
In terms of high-voltage disconnection, it achieves instantaneous disconnection of high-voltage circuits within 0.01 seconds after impact, and completes the residual high-voltage energy release from the vehicle within 0.2 seconds, setting a new industry record, according to the company.
