It’s amazing what China’s CATL has achieved with its latest product if its claims are to be believed.
CATL, the world’s largest electric vehicle (EV) battery maker, has launched the so-called Bedrock Chassis, an ultra-safe EV platform capable of withstanding a 120-kilometer-per-hour frontal pole impact without catching fire or exploding.
This groundbreaking achievement far exceeds the industry standard frontal impact test speed of 56kph set by the China New Car Assessment Program (C-NCAP).
The Bedrock Chassis integrates CATL’s advanced battery cells directly into the chassis, a design that absorbs 85% of collision energy, significantly higher than the 60% absorption typical of traditional chassis systems.
The chassis passed what CATL describes as the world’s most stringent safety tests, including a frontal pole crash at 120kph—equivalent to falling from a 56-metre-high building — setting a new industry benchmark for safety.
To achieve this, CATL incorporated a three-dimensional biomimetic tortoise shell structure, an aircraft carrier-grade arresting system, and advanced materials such as submarine-grade hot-formed steel and aerospace-grade aluminum alloy.
These features distribute impact forces, reduce cabin intrusion, and enhance overall rigidity. Further safety innovations include ultra-safe battery cells, technology that disconnects high-voltage circuits within 0.01 seconds of impact, and a system that discharges residual energy in 0.2 seconds.
Beyond safety, the Bedrock Chassis accelerates vehicle development, cutting mass production timelines from 36 months to just 12-18 months. Its modular design allows automakers to create multiple vehicle models on a single platform, supporting advanced driver-assistance systems and enabling up to L4 autonomous driving capabilities.
The chassis also delivers a range of up to 1,000km on a single charge.
Avatr, co-owned by CATL, Changan Auto, and Huawei, will be the first automaker to use the platform, though no timeline was provided for vehicle launches.
CATL chairman Robin Zeng said the platform has the potential to revolutionise EV manufacturing, reducing development costs to as low as US$10 million and enabling niche manufacturers to achieve profitability with just 10,000 units sold annually.
The Bedrock Chassis has drawn interest from automakers like Porsche and stakeholders in emerging EV markets such as the UAE.
This innovation is part of CATL’s efforts to maintain its 37% global EV battery market share and expand its presence in related areas, including battery swapping and micro power grids.
