CATL has unveiled a skateboard chassis called the Bedrock Chassis, which emphasizes safety and envisions a future in which exterior design is highly customizable by customers.

The Chinese power battery giant introduced the Bedrock Chassis at an in Shanghai today, calling it the world's first ultra-safe skateboard chassis.

Key difference is that this can handle a 120km/hr front pole impact, this is 4.6 times higher impact energy compared to the a GNCAP 56km/hr frontal impact test.

The chassis is capable of absorbing 85 percent of the vehicle's collision energy, much higher than the traditional chassis absorbing about 60 percent of the energy, according to the company.

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 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.

Beyond high safety, the Bedrock Chassis, like the traditional skateboard chassis, can significantly improve the efficiency of new model development.

The Bedrock Chassis allows vehicle manufacturers to build multiple models based on a single chassis architecture, thereby reducing the time to mass-produce a vehicle from the traditional 36 months or longer to 12-18 months, according to CATL.

Moreover, the chassis breaks through safety and styling constraints, expanding design flexibility through a design that decouples the chassis from the upper body.

With the support of the chassis, the era of uniquely designed vehicles for everyone will soon come, said CATL.

The Bedrock Chassis also supports mechanical decoupling and software decoupling to realize L3~L4 intelligent driving capabilities.

China's CATL launches EV chassis, flagging safety as top selling point.

- EV battery giant says chassis withstands high impact speed
- Avatr, Changan Auto and Huawei to be first to use it
- Battery to have 1,000-km (620-mile) range



the world's largest electric vehicle battery maker, on Tuesday launched a new EV chassis that it says can withstand a 120-kph (75-mph) frontal impact without catching fire or exploding, as it touts safety as a key selling point.

The chassis has a battery capable of running for about 1,000 km (621.37 miles) on a single charge and reduces the time required for mass production of a vehicle to 12-18 months from the traditional 36 months or longer.

The company aims to sell the new EV platform - called "panshi" in Chinese, which translates to "bedrock" - to premium car makers seeking to accelerate development and reduce costs.

"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," said Ni Jun, CATL chief manufacturing officer.
The speed for a frontal impact safety test in the commonly used China New Car Assessment Program is 56km/h.

Such EV platforms are also known in the industry as "skateboard chassis", or flexible platforms that combine electric motors, batteries, controls and suspensions.

CATL has a global market share of roughly 37% in EV batteries, according to battery market tracker SNE Research.
