Most safety crashing tests are conducted at the novel speeds of 50 to 60 kmph. But CATL, who have been developing a new Bedrock chassis recently showcased the crash test of a new chassis at the high speed of 120 kmph. As per the statement that has been issued by CATL the risk of injury increases by 3% with every 1 km speed increase, if you increase the speed by 5 kmph the risk of injury nearly doubles. CATL have been focusing on using their new innovative technologies to develop a new EV chassis that would help the vehicle be safer and tackle high speed crashes with Ease.
The issue with EV chassis is that the battery itself can collapse under crash, and a crashed lithium battery can often spontaneously catch fire when its gets impacted. The chassis has been designed in such a manner that it can easily save the vehicle from such issues as well.
EV Crash Test
Beyond a simple crash test the vehicle was also tested against a pole . In a simple crash test the high tech chassis of the CATL showcased no A-pillar deformity and even the battery unit showcased no signs of deformity under pressure. When the Bed Rock chassis was crash tested against a pole the results were similar. The impact could not penetrate into the cabin of the vehicle and beyond that the Energy unit was not impacted as well.
EV Crash Test Results
The reason behind such a performance in crash test would be the use of Aircraft Carrier Grade Blocking Structure that transfers the impact throughout the chassis rather than collapsing. To keep the battery of the vehicle safe the company has used a 3d Bionic Tortoise shell structure that allows the battery to maintain its form even after being under the heaviest of impacts. Stepping beyond the normal the company has further coated the whole chassis in a High Ductility Energy absorbing insulation film that would absorb the impact and beyond that keep the battery away from deformation.
Since most normal carsh tests are done at 60 to 50 km/h, this one is special. Accelerating a car to a speed of around 120km/h and then crashing would most definitely increase the dangers of impact. But the Bedrock chassis by CATL seemingly withstands it with ease.
