When paired with other manufacturing innovations like giant Giga cast machines (used by companies like Tesla and Hyundai), the production process becomes even more efficient. These machines can create large sections of a car's body in a single piece, further simplifying assembly.

Democratizing Car Production

While it's unlikely that this will lead to a flood of new car companies (established manufacturers like BYD and Tesla still have significant advantages in scale and efficiency), it does open up new possibilities for niche manufacturers or companies looking to enter the EV market.

Safety: The Bedrock Chassis's Standout Feature

Perhaps the most impressive aspect of the Bedrock chassis is its safety features. CATL has gone to great lengths to ensure that this platform sets new standards for vehicle safety.

Unparalleled Crash Protection

The Bedrock chassis has been tested in frontal collisions against a pole at speeds of 120 km/h (75 mph). In these tests, the battery did not catch fire or explode - a remarkable achievement considering the severity of such an impact.

Advanced Materials and Design

CATL has used a combination of high-tech materials in the construction of the Bedrock chassis:

• Submarine-grade hot-formed steel for structural components
• Aerospace-grade aluminum alloy for non-impact areas
• Multiple barrier structures for increased rigidity

This combination of materials contributes to the chassis's exceptional strength and safety performance.

Rapid Safety Systems

The Bedrock chassis incorporates advanced safety systems that activate almost instantaneously in the event of a collision:

• The high-voltage circuit can be disconnected in 0.01 seconds after impact
• Battery discharge is completed in 0.2 seconds

These rapid response times significantly reduce the risk of fire or other electrical hazards following a crash.

Superior Energy Absorption

One of the most impressive features of the Bedrock chassis is its ability to absorb 85% of the vehicle's collision energy. This is a substantial improvement over traditional chassis designs, which typically absorb around 60% of collision energy.

Rigorous Testing

CATL has put the Bedrock chassis through a series of demanding tests to prove its safety credentials:

• High-speed sled impact tests at 37 mph
• 90° bending tests
• Sawing tests
• Nail penetration tests

In all these tests, the battery cells demonstrated remarkable resilience, refusing to catch fire or explode.

Comparing EV Safety to Traditional Vehicles

The safety features of the Bedrock chassis highlight the growing safety advantage of electric vehicles over their internal combustion engine (ICE) counterparts.

EVs: The New Safety Standard

Even before the introduction of the Bedrock chassis, EVs were already proving to be safer than ICE vehicles in many scenarios. The top-scoring vehicles in Euro NCAP safety tests are consistently electric models.

Structural Advantages

The inherent design of EVs, with their large battery packs typically located in the floor of the vehicle, provides several safety advantages:

• Lower center of gravity, reducing the risk of rollovers
• Large crumple zones in the front and rear, due to the absence of a traditional engine
• Increased rigidity from the battery pack's integration into the vehicle structure

The Bedrock Chassis: Raising the Bar

The Bedrock chassis takes these inherent EV safety advantages and pushes them even further. Its ability to withstand high-speed impacts without fire or explosion sets a new benchmark for vehicle safety.
