These Chinese who keep copying western knowledge sure seem to teach us a few things worth learning. https://electrek.co/2024/12/24/catl-launches-worlds-first-ultra-safe-ev-skateboard-chassis/ CATL launches the ‘world’s first ultra-safe’ EV skateboard chassis Peter Johnson | Dec 24 2024 - CATL-world's-first-chassis China’s CATL launched its new Bedrock Chassis on Monday, calling it “the world’s first ultra-safe skateboard chassis.” The global EV battery leader said its newest tech “activates a trillion yuan market” as the new standard for intelligent vehicle design. According to CATL, it will also end the belief that gas-powered cars are safer than EVs. CATL launches the world’s first ultra-safe EV chassis On December 24, CATL officially launched the new Bedrock Chassis with “outstanding” safety performance. The company proved it in a video presented during the launch event. The video showed a prototype model’s front impact at 120 km/h (about 75 mph) without exploding or catching fire. CATL claims its newest tech “sets a new standard for intelligent chassis safety” with comprehensive protection across all scenarios and speed ranges. According to CATL, the Bedrock Chassis passed the world’s first “highest speed +strongest impact” dual extreme safety test. In China, the commonly used speed for frontal impact safety tests in the C-NCAP (China New Car Assessment Program) is 56 km/h (35 mph). At that speed, the collision generates energy equivalent to falling from a 12-meter-high (39-foot) building. At 120 km/h, it’s like dropping 56 meters (183 feet). According to CATL, the collision energy is 4.6 times greater. Ni Jun, Chief Manufacturing Officer of CATL, during the Bedrock Chassis launch event (Source: CATL) During the launch, Ni Jun, CATL’s chief manufacturing officer, said, “Safety is the core of CATL—it’s part of our DNA.” A trillion yuan market There has been no previous instance of a new energy vehicle (NEV) “daring to challenge a 120 km/h frontal pole impact test,” the company said during the event. With a battery-centered design, CATL’s new Bedrock Chassis directly integrates the battery cells into the unit. The design enables it to absorb 85% of the vehicle’s collision energy compared to about 60% by a traditional chassis. The unit features an “ultra-safe battery cell design,” disconnecting the high-voltage circuit instantly within 0.01 seconds. It will then complete the vehicle’s residual high-voltage energy discharge within 0.2 seconds, a new industry record.
